Killer Profile
"The Ice Truck Killer"
Number of Victims
At least 15
Modus Operandi
Killing Method
Moser straps his victims to a table, tilts them upside-down (or suspends them from the ceiling,) slits their carotid artery and allows them to simply bleed out. Death by exsanguination. In a few occasions he just kills them in any way possible.
Method of Disposal
Usually none. Bodies are displayed in plain-sight.
As with his biological brother Dexter Morgan, Brian Moser witnessed the brutal dismemberment of his mother at the age of five. This left him mentally scarred and gave him very strong inclinations toward homicidal acts. Unlike Dexter, he did not have the guidance of Harry Morgan along with The Code of Harry to prevent him from killing the innocent.

This Character is also a Dark Passenger

"You can't be a hero and a killer. IT DOESN'T WORK THAT WAY!" ~Brian Moser to Dexter

Brian Moser[2] (also known under the pseudonym Rudy Cooper[3]) is a Character in DEXTER, introduced during the show's debut season. During the season finale, Brian is revealed to be Dexter Morgan's biological older brother and the son of Laura Moser. He is one of Debra Morgan's past lovers.[4] It is never specified whether or not Joe Driscoll is Brian's father.

Brian is the First Main Antagonist in the series and the first major Serial Killer (aside from Dexter), with a body count of over twenty victims. The police refer to him as The Ice Truck Killer or ITK. Of note, he is the only serial killer to appear in both the Novels and the television series. In the series, he is mentioned in every season by either Dexter or Debra Morgan, except in season eight. There is, instead, a visual nod to him in the series finale in the form of a Miami Chills ice box.

Season Six sees Brian's partial return, acting in place of the role of Harry Morgan, when Dexter chose his darkness over the light in dealing with the savagery of Nick, the man who killed his friend, Brother Sam. Brian, as a strong personification of Dexter's Dark Passenger, urges Dexter to forgo The Code of Harry and embark on a life of killing without restraint. However, Dexter manages to fight off the temptation in favor of Harry's teachings.


Brian is a rather tall and thin man with curly black hair and a distinct facial structure. He is handsome, just like his brother Dexter Morgan, but more rugged and rough around the edges. He's also fairly strong and could be on par with Dexter, minus the martial arts training that Dexter has had. He has green eyes and a scar on the left side of his top lip (due to an injury received earlier in the season).

His typical work attire consists of a lab coat, dress shirt with a tie, and dress pants. Casually, he is often seen wearing a red button-down shirt and, beneath it, a white undershirt. When killing his victims, he typically wears all black clothing, an apron, protective gloves, and something to protect his face (much like his brother).


Brian's personality is complex. He shows different personas, depending on the circumstances. Brian is also very intelligent, as shown throughout the first season. He evades the police, tricks Debra Morgan into loving him, and even deceives Dexter. Brian has a fascination for prostheses and limbs which stems from a traumatic event that he experienced at an early age. He watched his mother being brutally dismembered in a cargo container. Like his younger brother, Dexter, he can easily hide his true self by putting on a mask of deception. Brian was never taught a Code which left him free to claim any life.

Young "Biney"

Brian was a playful child and had a quiet nature about him. He spent most of his time with his younger brother, Dexter, and his mother, Laura Moser. He was very fond of his little brother and hugged him often. When Dexter fell off his skateboard, he complimented the wipe-out, but told him to be more careful next time.

After their mother was dismembered in front of them, they were abandoned together inside the blood-filled shipping container. Caring about his little brother was the only part of Brian's innocence that did not die during that traumatic event. It took two days before Brian and Dexter were found by police, sitting in blood. Despite Brian's pleas, the two of them were separated. Dexter was taken in by a foster family while Brian was admitted into a Tampa mental hospital, where he grew up. Brian was left with nothing but a memory of the family he once had.

Mental Patient

Brian spent his youth in a mental institution and was diagnosed with Antisocial Personality Disorder. While there, he learned ways to adapt to society, but he also picked up on the ability to mask his true self. Despite having the obvious dysfunction of needing to kill, he was able to hide it so well that he was released in 1989, at the age of twenty-one.

Little else is known about Brian during this time, except what he reveals during a conversation with Dexter in Born Free: “You’re trapped in a lie, little brother, the same lie they tried forcing me into...doctors, therapists, group leaders - the family they were...When Harry found me, all he saw was a fucked-up kid. They all did, so they locked me up...I know what you’ve gone through all these years -- the isolation, the otherness, the hunger that’s never satisfied, but you’re not alone, anymore, Dexter. You can be yourself with me, your real, genuine self. It takes the breath away, doesn’t it?”

Ice Truck Killer

The witnessing of his mother's murder instilled dark urges in Brian that drove him to kill. It is unclear whether he dismembered his victims in the past or if he started doing it as part of his plan to reconnect with Dexter.

2013-08-23 2151

Brian spills his blood-buckets into Room 103 of the Marina View Hotel, in order to jog Dexter's memory.

It's revealed that before Brian cuts up his victims, he drains them of their blood. Later, he covers a hotel room with their collective blood in his scheme to force his brother to remember the Shipping Yard Massacre.

To spark Dexter's memory, Brian leaves many detailed and encrypted clues. They include body parts and doll pieces, different colored fingernails, photos of Dexter's past, the blood-filled room, and the actual Moser home. In the end, the brothers do reunite - briefly. Brian, although he is very intelligent, calculating, and cautious, did not anticipate Dexter's reaction to his demand for Debra's death.

In the Mask, as Rudy

Rudy Cooper is the the name of a man that Brian murdered in 1998. He then stole his identity in order to get close to Dexter. Under the alias of Rudy Cooper, Brian comes off as a kind and charming man whose occupation is to help severely injured patients. According to Rudy, he became a prosthetist because his mother had lost both of her legs in an accident and he regretted his inability to help her.

Rudy is the opposite of Dexter in outward personality. He doesn't mind kicking back and having fun with others. He shows an appreciation for rock and classical music. Rudy also knows how to dance as well as "air guitar," and appears to be ambidextrous. Rudy seems to be just a normal guy with no issues - the perfect mask for the public.


Brian (Rudy) and Deb kiss

After he (as ITK) cuts off Tony Tucci's leg and hand, Rudy provides treatment for his victim, fitting him with an artificial hand and leg. This gives Rudy the opportunity to start a casual flirtation with officer Debra Morgan. After surprising Tucci with a prostitute named Shanda, Debra stands guard outside his room and notices Rudy who gives her a wide smile before he departs. Later on, at Tucci's release from the hospital, Debra and Rudy have a moment to speak with one another. He remarks that he studied the human form at the University of Paris-Sorbonne which impresses her.

Debra's romantic feelings toward Rudy escalate after he asks her to dinner and it results in the two of them sharing a passionate kiss. Rudy's affection for Debra seems sincere but Brian's goal is to get close to Dexter. Before long, she falls in love with Rudy. Unfortunately, Debra is a part of Brian's plan and, after she serves his purpose, he wants her to die

Around Dexter, Rudy appears as a concerned friend and Debra's caring boyfriend. However, Dexter is somewhat evasive when talking to Rudy and finds it awkward that this guy wants to be close with him. Brian likely feels this rejection but he needs to keep his guise until his big reveal to Dexter.

Without the Mask

Brian, without the mask, is a man determined to establish a bond with his brother, Dexter Morgan. To make this happen, he devised a complex plan that took years to bring to fruition. This included setting up a large refrigeration unit in his apartment where he could dismember his victims in order to display them as public messages to his brother. Brian also bought his childhood home under his real name (per Born Free and his driver license address).

Human life has little to no value to this Brian. He has no code and will kill anyone, especially those that get in his way or have something that he wants (e.g. Rudy Cooper's identity, Fred's car). He is quite ruthless and kills in a casual manner. Often, he makes cocky, sarcastic remarks, and prefers not having to hide behind another personality. Except for the murder of Rudy Cooper (in 1998), Brian's kill count and methods are unknown from 1989 (when he was released from the mental hospital) until 2006 (when The Ice Truck Killer appeared on the scene),

When it comes to Dexter, Brian still feels the same way toward him that he did as a child - caring and protective. Toward anyone else, he feels nothing but derision.

In Season Six, Brian is represented by the Passenger - a joking, energetic, evil man that seeks fun and freedom.

Modus operandi

  • Although Dexter and Debra speculated that Brian committed his murders in a stolen ice truck (hence his name), it is revealed in episode 8 that he had a custom refrigeration unit in his apartment. He often dismembered his victims there, wrapped up the pieces, and left them in public areas for the police to find. One of his habits was to drain the blood from his victims (which earned Dexter's admiration). Brian did this by using a machine to hoist his victims up by their legs and then slice their carotid arteries. The blood was pumped by their hearts into a bucket. Brian later used the collective blood of his victims to cover an entire hotel room. This caused his brother, Dexter, to remember a part of his past. Dexter used this same ritual to make his brother's death look like a suicide.
  • Apart from his ITK modus operandi, Brian killed people in other ways, one of which was used to murder Joe Driscoll (and possibly Irma Holt). Joe was slipped a sedative and then injected with diabetic insulin, which caused his death to appear as cardiac arrest. This method proved to be very successful as Joe was never suspected of being murdered (except by Dexter). The fact that Brian could kill and leave no clues or witnesses made him one of the most dangerous serial killers in the series.


Note: It is probable that Brian has a much higher victim count.

Other Kills


Early life



The Moser Household

Brian Moser was born in 1968 to Laura Moser and Joe Driscoll. Based on his shy, quiet nature when he's five it's likely he grew up in a time where Joe may have either been abusive or neglectful (as their exact relationship with one another is unclear however Brian did eventually kill his father so it is suggested that they weren't close). In 1971, his mother Laura gives birth to a second child named Dexter and from that moment on Brian looked out for his little brother. They would continue to live in a small house at 1235 Mangrove Drive in Miami, Florida and as Brian became old enough, he started to attend school.


Brian playing hide and seek with his brother


Dexter, his older brother "Biney" and his mother Laura

The earliest known event in Brian's life were the times he spent at his mother's house roughly around the age of 5, often playing hide and seek with her as well as his little brother Dexter. Dexter was the more energetic, happy child that laughed happily and teased with joy when hiding from his mother who treated him in just the same generous way. Brian was more quiet, reserved and kept in the back but he had a deep affection for his little brother, often cradling him in his arms or holding onto him as a protector and caring brother would.


Brian comforts his brother after a skateboard accident


Some time later Dexter actually managed to ride on Brian's skateboard and had a wipe out, Brian comforted him by telling him it was the best wipe out he'd ever seen and puts a band aid on his knee while giving him tips to bend his knees the next time he tries while Dexter nods in agreement. The two can often be seen playing together and Brian/Biney will usually be hugging Dexter, the two having a great childhood together.


Laura and Dexter at an interview for Harry

Unfortunately Dexter's mother was a drug addict (likely entering the trade when her boyfriend at the time, Joe Driscoll, returned from the Vietnam War and started becoming an addict himself), this never affected her love for her boys but it put her at high risk with certain parties. She met Detective Harry Morgan and began acting as his informant in the Estrada cartel, trying to provide intel that would help bring down the drug kingpin. On Friday September 28, 1973 she met with Harry in an interview while bringing her youngest son Dexter along, while her older son Brian was in school. Laura told him that she wanted out of this, that it was far too risky for her and her boys and Harry assured her that nothing would happen to her or her children. She felt that her life may be on the line believing they were followed to the park the previous day, information that would later turn out to be a love affair. While Harry was seeing Laura despite being with his wife Doris Morgan, Laura was in fact also cheating on her boyfriend Joe. Harry closed out the interview, patting Dexter on the head even then somewhat symbolizing the later fatherhood figure he would become.

Shipping Yard Massacre


On Wednesday October 3, 1973 Laura Moser, her two sons Dexter and Brian, as well as three other drug users were herded into the shipping container CBAN 348 9 by Estrada's henchmen: Santos Jimenez, Lipsey and Welsh. It is believed that just Santos wielded the chainsaw, as the other two are often seen likely standing there to prevent anyone from escaping.


"Close your eyes, Dexter...don't look. Mommy loves you Dexter.."


Dexter in a pool of his mother's blood, "reborn".

The three unnamed victims were all slain by the chainsaw, leaving Laura Moser for last begging them not to do this in front of her baby. She screamed and cried as they revved the chainsaw, turning then to give a final smile to Dexter (most likely because he was the youngest at the time and the baby in the family) She said to close his eyes, not to look and that she loved him before Santos finally cut into her, killing Laura in front of both of her sons with no remorse.


Dexter and Brian, forced to sit in blood for two days

Santos and his comrades fled the area while Dexter and Brian sat there, for two entire days sitting in blood that would forever change both boys. Brian, who was older, would always remember this experience but Dexter was shut down emotionally for the next 30 years he wouldn't know how to be human anymore. A happy childhood ended in tragedy, to create two boys who would grow up to be serial killers. Only one of them, however, was given the means to control and focus these urges thanks to the first man on scene, Harry Morgan. Brian suffered with the memories of this event, it helped fuel his curiosity in the human body as well as dismemberment and likely the amount of blood in the container helped in his style to drain the victims of all of their blood.


Dexter losing grip of his brother's hand as he's carried away

Detective Morgan opened the shipping container door, startled by the absolute carnage inside. He spotted the two children however and moved in to pick up the younger, Dexter. As Harry was picking up Dexter, he held on tightly to his brother's hand before it slipped from his grasp and both boys called out to one another. Harry looked Brian in the eyes and saw (what Brian later claimed in his adult years) "a fucked up kid", rather than taking him as well he left the container while Brian screamed "please don't leave me Dexter!".

As he got outside, he told the other officers with him to get in there immediately and Brian was recovered but Harry held onto Dexter, holding him close as he said everything would be alright. He made his way to the car while Dexter looked on without emotion to this accident, eventually blocking it out of his mind for most of his life. Santos Jimenez and the other two were arrested shortly thereafter for the crime, Santos managed to cut a deal and moved to Naples when given the chance but one of the other two died while the other has life without parole in prison. Joe Driscoll, their father, found out about the carnage and fearing for his own life fled Miami leaving behind his children behind and apparently settled in Dade City, where he'd eventually drop his drug addiction after a stay in prison and went on to live a quiet, lonely life. Dexter was brought into the Morgan family, where he'd be raised by Harry and become the brother of Debra Morgan.

Growing Up

According to Brian, all Harry saw in him was a "fucked up kid" as did the other officers so rather than approve him to go with his brother Dexter, he was placed inside of a mental facility in Tampa Bay, Florida. His only family now was a group of other disturbed children and then the psychiatrists working with him, the only thing he held onto were the memories of what happened to his mother and the thought of his brother, Dexter. It's unknown where Brian acquired the ability to mask himself and blend in the way Harry taught Dexter, as there was no such guidance to aide him in his life. With the uncontrollable urge unchanneled but never unleashed, Brian never learned restraint or a Code to choose which people to kill...meaning that he was free to claim any life he desired. It is likely without Harry's guidance that Dexter would have been the same way Brian is in his adult life.

This ability to hide who he truly was made him appear fit for society, so as he grew up studying in the mental hospital rather than an actual school he eventually was released at the age of 21. His life after that seemingly vanished from record however, as the man named Brian Moser disappeared...


Dexter Morgan - As a child, Brian loved and protected his younger brother, Dexter. After they were separated following their mother's murder, Brian held onto the memory of him. As an adult, he tracked down Dexter, who was still living in Miami. Once Brian discovered that his brother was a killer like him, he decided to play a game with Dexter to stir his remembrance. Everything Brian did during the Ice Truck Killer Investigation was a message to Dexter. Brian was smart, cunning, and even spent time with Dexter under the alias, Rudy Cooper. However, Brian couldn't tolerate Dexter's loyalty to his adoptive sister, Debra, whom he used as a part of his plan. When Brian insisted that Debra must die, Dexter decided to kill him. In the end, Brian still held onto the affection he felt for his brother despite Dexter's choice, and did not show anger toward him in his final moments.

Debra Morgan - Because Brian was skilled at hiding his true self and faking his emotions, his romantic feelings towards Debra (under the guise of Rudy) appeared sincere. However, after he captured Debra, he made it clear to her that he never actually loved her. Of note, he had a deep interest in Debra's legs, fitting in with his career in prosthetics.

Laura Moser - In contrast to Dexter, Brian remembered his mother's brutal murder. The event warped him into becoming a ruthless serial killer. During the Ice Truck Killer Investigation, Brian carefully dismembered and drained his victims of their blood, in order to send a message to Dexter. Also, he was seemingly fascinated in the way that his mother painted her fingernails in five different colors. Using distinct colors, Brian painted the fingernails of Monique's prosthetic hand, the doll's hand, and the frozen fingertips. He then left them all as clues for Dexter. Of note, only his female victims were cut up into pieces.

Joe Driscoll - His relationship with Joe, his (assumed) father, is unclear, but he hadn't seen him since childhood. As a way to reconnect with his long lost brother, Brian killed Joe, knowing that Dexter would inherit his house. After he tracked Joe down and accessed his house while disguised as a cable repairman. Brian was able to slip Joe a sedative, and then inject him with diabetic insulin. This caused Joe's death to appear as a non-suspicious heart attack. As Rudy Cooper, Brian accompanied Debra to help Dexter clear out Joe's house. While there, he was able to spend time with Dexter. After Dexter stole Joe's cremated remains, Dexter and Brian together scattered Joe's cremated remains near his favorite bowling alley.

Connections to Others

Dexter Morgan - The Ice Truck Killer's crime scenes in Miami were meant entirely for his brother, Dexter. Before Brian tracked down Dexter, he may have used other ways to dispose of bodies since, at least, one of his victims was not left out on display.

Debra Morgan - She fell in love with Brian (under the name of Rudy) while he was using her as part of his master plan to get close to Dexter. It blindsided her when he revealed himself as the ITK. Even after Brian's death, Debra was still so fearful that she temporarily moved in with Dexter. Of note, she rarely calls Brian his actual name, but still uses his alias, "Rudy."

Harry Morgan - Harry knew about both Brian and Dexter before the Shipyard Massacre as he was intimate with Laura Moser, their mother and his informant. Harry even made a promise that he would let nothing happen to her or her boys, though she unfortunately meets her death in the shipping container. When Harry enters the container he picks up Dexter and looks Brian in the eye, seeing that he's a "fucked up kid" (according to Brian) and rather than go back to get him by himself he takes Dexter out then orders several other police officers to get in there immediately. Harry continued to hide Brian's existence from Dexter and it's unknown whether or not he ever met Brian again in his lifetime, as Brian had already been released by the time Harry eventually killed himself. Brian personally despised Harry for taking Dexter away from him and implementing the "code".

Laura Moser - As his mother, Laura cared for both her boys lovingly. After Dexter was born, he became her baby of sorts but it's likely she still cared greatly for Brian. After her death, Brian never forgot her and became obsessed with the way she died, in addition to the color that Laura painted her fingernails.

Joe Driscoll - As his father, it's unknown the relationship between the two. Brian eventually ended his life despite the importance of family, likely suggesting that Brian didn't care that much for his father (for either letting their mother die or for reasons between the two).

Tony Tucci - His first attempted victim, a man he continued to cut body parts off of only to make sure that he was medically tended to and kept healthy. Brian planned on Tucci being Dexter's kill, so the longer Dexter took to realize the truth the more likely body parts would find themselves showing up at various locations in Dexter's past. At first Brian insured that Tucci would be a fall guy, leading the police on a wild goose chase but in the end after Dexter decided to spare Tucci, Rudy ended up helping put him back together. It is likely that Brian (as Rudy) felt some sort of pride in "fixing" taking him apart, he made the man appreciate life more once he was saved and as gratitude he didn't seem to mind creating the prosthetic parts needed for Tucci to have a life again.

Angel Batista - Angel begins following up a lead based on a woman he met named Monique, leading him to talk to Brian (as Rudy Cooper) regarding prosthetics. At first Brian readies himself to kill Angel if he knew too much but decides not to when it seems Angel has no idea it's him...that is until Angel begins to snoop further and Brian strikes him down in a garage to protect himself. Angel survives the attack and is later able to figure out that Rudy's true identity is Brian Moser.

Monique - Monique is a prostitute that met with Brian over a year before his killings in Miami, she had a strong fascination for him and how he was to her as a John. At first he was violent until he noticed the imperfection as well as the prosthetic arm, then his tune changed to a gentle (and worshiping) attitude. Ultimately however, to cover his tracks he turns Monique into one of his victims despite the fact that "Imperfection saved her the first time".

Camilla Figg - Camilla knew about Brian's existence, but insured that this data would never reach Dexter to protect him. After she is on her death bed, she reveals to Dexter that she was able to connect the truth about the Ice Truck Killer to Dexter's brother and is one of the few people that knows this reality. Dexter, before helping her pass on, tells her that she was right about Brian and that he killed him. Before she dies, she says that he did good killing him.

Ryan Chambers - Ryan is an intern for Vince Masuka that joins the department during the events of the Doomsday Killer Investigation. Masuka feeling that he wants to impress her, takes up evidence from the investigation to show her and says that he remembered her saying she was "really into the case". Ryan admits that she was actually obsessed with it, following it night and the box is opened and she sees first Brian's hospital badge, then the Prosthetic Hand worn by Monique. She looks at it in awe, placing her hand close to where the fingertips show each differently colored nail, claiming that she painted her nails just like that herself. Following this event, Ryan actually steals the hand from evidence and sells it on a website...something that Masuka doesn't take lightly to (ultimately removing her as an intern). Of note, Ryan also mentioned the Bay Harbor Butcher and Trinity Killer.

Louis Greene - Louis is the replacement intern over Ryan Chambers for Vince Masuka. He's a computer genius who aides in the Doomsday Killer Investigation while also helping Vince out with the "problem" regarding the sold hand. In reality, it's revealed that Louis is actually the buyer of the hand and was the original caller who asked about it back when Ryan was still working there. Louis is a mysterious character whose exact connection to ITK or Dexter is unknown, however he idolizes Dexter Morgan and in a way similar to Brian himself, appears to be getting close to Jamie Batista in order to get closer to Dexter. However he may genuinely have feelings for her, it can't be denied that his fascination in Dexter is noteworthy.

Michelle Ross - In Debra's confessions to her therapist, she reveals that not only was she dating a serial killer but that he was Dexter's biological brother. Recently Ross has put a lot of focus on that fact, that she chose to be with a serial killer and she's responsible for that decision even though Debra feels she couldn't have known that truth about him.

Travis Marshall - While not technically connected, many comparisons are made between the way Travis kills people and the way Brian did. First the dismemberment of Nathan Roberts, similar to the way Brian cut up his victims. Second, the need to convey a message...but as Dexter says, Brian's were "tailor-made for him"...the message Travis conveys is to the world. Third and most recently, Trent Casey was strung up to bleed out much like the way Brian handled his victims and the buckets of blood (used as part of a trap) is also similar.

Season One

Season One primarily follows the exploits of a man dubbed the Ice Truck Killer and his game of wits with serial killer Dexter Morgan.

Prior to Miami Kills

Brian traveled the country and even across the world following his release from the Tampa Mental Institution after being cleared at Age 21. It is believed that due to his isolation in the facility, he chose to travel in order to secure a life for himself and see what had passed him by growing up from the 1970s and part of the 80's. At some point in his lifetime he traveled to Paris, France where he would study the human form at the University of Paris-Sorbonne,[5] that helped provide an acute knowledge of the human body (which would be used later in his life for the dismemberment of his victims). Brian states that a little while after he entered Prosthetics, though it's likely at this time he had already killed the man named Rudy Cooper in 1998, assuming his identity including all of his information in order to enter the medical field.

It is unknown how long Brian assumed the style he adopted of draining the victims of their blood then dismembering them piece by piece or when he made his first actual kill (by the way Brian describes it, the original Rudy does not sound like the first victim) but one thing was for certain: the hunger never stopped. It is likely that before he finally tracked down his brother Brian killed more than 50 people but this number can't be confirmed only the three prior to his arrival in Miami. It is likely that in a way similar to Arthur Mitchell, Brian transferred himself to various locations throughout the country in search of his brother while also working as a Prosthetic surgeon, allowing him the funds he needed while pursuing a field that best fit his interest in the human body and dismemberment (formed by watching his mother chainsawed to pieces in front of him). Here he would practice on his victims while trying to find the elusive Dexter Moser but was never clear on a location, until 2006. After leaving two bodies in Broward, Brian's travels brought him back to Miami where he discovered that Dexter Moser was in fact named Dexter Morgan.

Brian did his research at this point, able to trace back to the cop who found them at the scene Harry Morgan as well as his adoptive sister Debra Morgan. The more surprising fact is that in this time he learned about Dexter's life growing up (most likely when Dexter went out, he would sneak in to learn everything about him), at some point in one of Dexter's many victims Brian tailed him and observed the way his brother was. A feeling deep inside both made him feel overjoyed that his brother was just the same way that Brian had always been and also prompted him to finally make a move to show him there's someone else out there just like Dexter.

He started to construct an elaborate plan that would guarantee that he would not only show Dexter who he truly was (as he figured out that Dexter must not have had memory of the past, in addition he knew of Dexter's choice to only target criminals based on Harry's teachings), but reunite the two of them after making all the facts of Dexter's past come to light. So he started with a single victim, a prostitute left at a hotel...

Bloodless Victims

Dexter: "No blood. No sticky, hot, messy awful blood. No blood at all. Why hadn't I thought of that? No blood. What a beautiful idea"


First crime scene for ITK

Dexter Morgan returns home to find a message on his answering machine from his sister Debra Morgan regarding a murder at the Seven Seas Motel, she personally requests that he appears there with a "pretty fucking please with cheese on top" which causes him to laugh and he readies himself to show up on scene. As he arrives, he passes through the yellow tape looking around slightly until he spots his sister (in her undercover outfit) who pulls him into her motel room. She does a run-through on the body, saying that it's the third victim in the past five months, with the other two victims found in Broward chopped up just like this one. Dexter seems a little surprised at a Serial killer but Debra asks him if he can help her out, get a hunch on the situation that may enable her to finally transfer out of Vice into Miami Metro Homicide, where her brother works alongside the department as a forensic blood spatter analyst. Dexter agrees and heads outside, probably not expecting more than the usual work.

Dexter stunned by the amazing work of the hooker killer.


Angel points out an oddity about the leg

As he moves down into the pool he is greeted by the always perverse Vince Masuka, his coworker with a sense of humor. After making a joke about his attraction to Debra, he asks why Dexter is even here and Dexter replies by saying it's a crime scene though Masuka points out that he does blood spatter and there isn't any at the scene. This catches Dexter by surprise, something he hadn't thought of before as Masuka explains there's no blood in, on or around the body at all before he asks Detective Angel Batista to go ahead and show the body to Dexter. He approaches anxious to see the body, his face lined with an expression of awe while viewing the corpse of this dismembered corpse wondering to himself just how could he get rid of the blood? He begins to praise the work in his mind, saying that he's never seen such clean and neat dead flesh feeling it's unique. Angel describes that the body isn't complete however, pointing out a rough cut that seems interrupted on the left thigh (leaving it in just three pieces, not four as the other leg) and they begin working on the angle of there possibly being a witness in the area. Dexter stands up, believing he can't think if there's no blood and finds a way to head out of there since he's the blood guy then there's nothing he can do there. As Dexter leaves the scene, he looks back thinking that perhaps this guy has exceeded his own abilities.


Second victim


Bone is "filet'd", no skin or muscle tissue period.

Debra Morgan is added to the case thanks to their father's old friend Captain Tom Matthews and Dexter later visits his girlfriend Rita Bennett in order to go out on a date with her. The two arrive at a festival of sorts, where all sorts of food items and partying commences while Dexter sort of plays along to seem normal enough. As the two stand at a crab table with Rita smashing the claws to find the meat inside, Dexter notices police off in the distance having sealed off a crime scene. Dexter's curiosity gets the best of him and he brings Rita towards the edge of the crowd before telling her he'll be right back. As he equips his forensic ID he notices a body laid out just like the one from earlier, beautifully preserved as well as bloodless.


"Damn. This guy is good"

Angel insults the killer by calling him a "Son of a Whore", a savage, an asshole killer...mainly because of the fact that they have to come in and work on a Friday Night. Dexter plays along agreeing, stating that this seems like the same guy and same pattern with Angel confirming no blood, absolutely bone dry. He begins to inform Dexter that the left leg has a difference in cut this time (it's rough at the ankle, not so much at the knee and midthigh is completely smooth). In addition, the very top of the thigh has the muscle and skin completely filet'd off revealing nothing but bone. Dexter claims that their killer is experimenting, trying to find the right way when Angel suddenly mentions the head missing, which causes Dexter some surprise. He thinks to himself now that this guy is good at what he does, smirking. In an awkward situation, Dexter later describers his fascination with the killer as pure artwork and even demonstrates his technique by "slicing" Rita's thigh at just the right point before getting somewhat sexually aroused by the incident. Rita isn't quite ready for that kind of contact and leaves Dexter feeling a bit out in the open, his head filled with thoughts of this new killer.

ITK Gets His Name


The moment Dexter says "Refrigerated Truck." Meaning Brian used them as a way to kill his Victims.

The following day Dexter Morgan meets with his sister Debra Morgan for lunch, having common small talk until Debra mentions an interesting fact: cell crystallization. She overheard a coroner say the word and brings up her observation about realizing the body parts looked cold, something that hits Dexter as an eye opener. He figures the cold would slow the blood flow and since this most recent victim was the only one showing those signs, the type of storage facility would have to be mobile so he discovers that the transportation has to be a Refrigerated Truck. Dexter figures then that Deb should check for any stolen refrigerated trucks in Miami, a point that she later mentions during a briefing by Lieutenant Maria LaGuerta regarding the case. Because of the nature behind Debra's attempt at explaining her observation (it's fairly nervous and stuttering), LaGuerta dismisses it as something she should "keep to herself".


Dexter sees the Ice Truck and decides to follow it

Dexter had been tracking a potential kill of his own during this investigation into the yet unknown Serial killer and he found this in a violent-rapist turned murderer named Jamie Jaworski. After ambushing him at a factory, Dexter went through his usual ritual before ending Jamie's life to appease his own Dark Passenger while also picking up the pieces to dispose of in his boat (as a note: these body parts were likely disposed of before seeing the Ice Truck and he was simply on his way home from the Mariana). Dexter parks in front of a hotel to take some time to admire the bloodslide for Jamie, feeling that it was a good night. From behind him a truck pulls up and turns on its light, rather bright to get Dexter's attention. He sits there for a moment until it decides to pass by him, surprisingly turning out to be a Refrigerated Truck, in fact it's an Ice Truck the perfect size to act as the transport for bodies, keeping them cold and preserved. Dexter can't believe his luck and begins to follow the truck, unknowingly reaching a dead end...and the truck begins to turn itself around, facing Dexter.


Dexter and Brian see each other for the first time in over 30 years, unknowingly to Dexter.


Head of the Party Victim thrown at the car.

Dexter begins to feel that he's in a dangerous situation, the Serial killer knew exactly that he was being followed and lured Dexter into a trap. The man faces Dexter's car for a moment before driving slowly towards him, turning up the brights on his high beams so that it prevents Dexter from getting a good look into the driver's seat. As Dexter tries to get glimpse something flies from the window and smacks against the windshield: it's the head of the woman from earlier, having been preserved in the front seat up there with him. Dexter gets out but is unable to see anything more of the truck before police arrive to deal with the situation. They paramedics give Dexter a basic eye test to see how he's doing and Maria LaGuerta arrives to talk about Debra's theory with the Ice Truck panning out seeing as Dexter pretty much just backed it up.


The Dismembered Doll

While Dexter is out, Brian sneaks into his house (for what may be referenced as the first instance but it is likely he has been here before) to figure out more about his brother. He leaves a Dismembered Doll in his freezer, with the head of the doll stuck to the front of the door before leaving. When Dexter returns during the day he notices the head "calling out" to him in a sense, as he moves forward playfully flicking the hair...he opens the door to discover the rest of the doll's body. The same expression of awe and curiosity fills Dexter, he enjoys the company of this new "playmate" and welcomes the challenge while admiring his opponent: this is more than just hunting a killer or being hunted by's a friendly gesture of wits and Dexter accepts.


"Hey, wanna play? And yes, I wanna play. I really, really do"

"Dexter: I suppose I should be upset. Even feel violated. But I'm not. No, in fact I think this is a friendly message. Kind of like..."Hey, wanna play?". And yes, I wanna play. I really, really do..."


Different colored nails, an oddity.

What is believed to either be the same day or the next, after Dexter returns home from a swim in the river he gets a knock on the door from his sister Debra Morgan thus prompting him to remove the head from the fridge and place it in the freezer along with the body before answering the door (feeling that trying to explain it would be "awkward"). Deb comes in and explains that Lieutenant Maria LaGuerta has everyone out looking for a hidden Refrigerated Truck, while Deb personally feels that this guy would more likely hide it in plain sight than attempt veiling it. LaGuerta, still feeling a strong distaste for Deb, dumps her "witness" theory on Deb to keep searching for one rather than actively join the investigation. Dexter suggests that if Deb can find that truck, she'll find her golden ticket into homicide. After she heads out and Dexter prepares himself for court, he looks in the freezer once more to fiddle with the parts admiring the doll head while putting each body part in a position like a "puzzle", until he discovers that one of the hands has an oddity: each of the five fingernails is colored differently (pink, yellow, purple, orange and green). This frustrates Dexter in a sense because he has no idea what it means (at the time...).


The Ice Truck (minus the Killer)


Bringing new meaning to the term "Put that finger on ice!"

The following day as Dexter is sleeping he receives a call from his sister saying that she found an Ice Truck (first time use of the word). Debra mentions that a cop named Juan Pierre called her about it following her mention of having Patrol keep an eye out on it. The truck was left there overnight and she asks Dexter if that was the truck he saw. He knows it is, but tells her that he wasn't sure (just to play along, he wants to keep the fact that the killer knows who he is a secret). She then notices that the truck's still on, something that results in Angel Batista as well as half the department arriving to turn it into a crime scene. They open up the back and step inside to notice a large ice block featuring the fingertips of a victim displayed perfectly in the center of the block in an surreal fashion. Dexter mentions that no blood was spilt, that the body was already drained beforehand then both he and Batista claim that it was done the old fashion way by slitting the jugular and hanging the body upside down to allow the heart to pump out the rest. Tom Matthews arrives and learns that Debra Morgan was responsible for the find, so he asks LaGuerta to compliment her on his behalf. LaGuerta instead grills her over it, saying that another "stunt like that" will not end well for her.


The truck is taken apart bit by bit.


Dexter realizes the messages are meant for him specifically

As part of protocol and in an attempt to find any type of clue as to who the killer is, the police department orders the deconstruction of every single piece of the Ice Truck. Dexter stands on watching, knowing that this guy is too careful to leave any kind of evidence...because he knows that if it were him, he'd do the same. Debra walks up and makes the same observation, something he acknowledges in his head as the real focus is wheeled off to the side: the ice block featuring fingertips. Later on at the lab, while Vince Masuka slowly melts the ice, Dexter stands on anxious to see what puzzle this killer has in store for the department. When enough of the ice clears to reveal the differently colored fingernails of each fingertip, it finally occurs to Dexter that these messages aren't for them...they're meant specifically for himself. The thrown head, the doll's body as well as the one hand painted different colors (the same colors as this victim's fingertips)...he feels that the killer is trying to impress him and as he smiles, he does feel impressed.


Dexter reveals the tips were removed postmortem


Deb finally gets her transfer to Homicide

A little later on it is Dexter himself (while in his mind) who verbally first says the name Ice Truck Killer, ultimately the name must have been decided shortly after finding the truck as the rest of the department begins using it as well. Interestingly, Brian does not use an Ice Truck after this point yet the name sticks regardless. Back at the lab Dexter confirms that because of the postmortem gloving around the joints, suggesting that the victim was already dead before she was relieved of her fingertips. While Dexter believes this is a sign of letting Dexter make the next move, he asks if there's an ID and Debra says that the victim was ID'd as Sheri Taylor, another prostitute. Deb is called in to talk with Captain Tom Matthews who makes the decision to have Maria LaGuerta transfer Deb out of Vice into Miami Metro Homicide due to her tremendous work on the case thus far. Debra is overexcited that she finally gets to pursue her dream and chase after the Ice Truck Killer as well. After Deb leaves and Tom is about to head out, LaGuerta asks him if he made the right decision...before he tells her that he promoted her after all as well. He exits saying that he wants this "Ice Truck Son of a Bitch" caught.


Pieces of the Puzzle Missing

Dexter returns home following a congratulations dinner with his sister as well as dealing with recent victim Matt Chambers, placing his slide in the box. As he turns around he notices a startling sight: the doll head he had placed in the freezer now sits pasted on the door again, something that proves that Brian had returned yet again inside of his house. He opens up the freezer though to see that the entire body of the doll is missing, something that he was not expecting and feels that this is a message that he needs to come find the killer. He is left with the head, something that Dexter later equips as sort of an unusual key chain.

Tony Tucci - Suspect

When leaving his latest victim at an ice hockey pitch, Brian encountered security guard Tony Tucci, forcing Tony to leave the victim's body parts in the field goal before taking Tucci prisoner. While LaGuerta initially assumed that Tucci was the killer, this theory was disproved when Brian began to leave Tony's disembodied limbs in various locations around the city, selecting his locations based on places where Dexter had been photographed with the Morgans after studying Dexter's family photo album, specifically choosing locations whose names had changed since the original photographs were taken. Eventually tracking Tucci to the basement of the hospital where Harry Morgan's

father had worked- the last photograph Dexter and Harry had taken together before Harry's illness left him incapacticed-, Dexter discovered Tucci, blindfolded and begging for death. Dexter deduced that the Ice Truck Killer had left him Tucci as a 'gift', but Dexter refused to kill Tucci as he didn't fit the Code, instead leaving an anonymous tip for Debra to find him (so she could be the hero). Whether through chance or deliberate planning (most likely the latter), Brian, under the guise of Rudy Cooper, was the doctor assigned to provide Tucci with prosthetic limbs, but Tucci never recognised his abductor (Brian had him blind-folded and was most likely wearing a mask when he abducted him).

Neil Perry - Fraud

Shortly after Tucci's rescue, Neil Perry was arrested as evidence emerged suggesting that he was the Ice Truck Killer. Although he was able to provide detailed descriptions of the crimes, Dexter doubted his claim from the beginning as his taxidermy suggested an attempt at creating fake images that the real killer would regard as pathetic, with his theory being confirmed when he met Perry in person and Perry had no idea who he was. LaGuerta, sharing this belief, was able to confirm Perry's innocence when he freaked out when she presented him with a decapitated head while allegedly asking for his 'expert opinion'; Perry had hacked the department's computers and claimed to be the killer for the notoriety of it.

Dexter Meets "Rudy"

Dexter Morgan, unaware of the identity of the killer or his relationship to him, is immediately fascinated with the Ice Truck Killer's methods. Brian hopes to reunite with his brother, who has shut out the traumatic memories of their past. Rudy uses the murders as a way of getting close to Dexter, with the hopes of encouraging him to abandon his double life and commit his murders freely with Brian. He starts leaving victim's body parts in significant places from Dexter's childhood. He also kidnaps a security guard named Tony Tucci and leaves him tied up for Dexter to find, hoping his brother will finish him off, but Dexter does not kill Tucci because of the principles he inherited from Harry.

When this plan fails, Brian decides to get more directly involved with Dexter's life. He starts dating Dexter's sister by adoption, Debra Morgan, as a way of getting closer to Dexter. Debra falls in love with Brian, but feels discouraged when he starts showing more interest in Dexter than in her. Brian starts easing Dexter into the truth of their past by killing their birth father, so that Dexter will get his inheritance and start learning about his past. He also continues to leave Dexter clues as the Ice Truck Killer, spraying a hotel room with blood to recreate the place their mother was murdered.

Brian stabs Angel Batista when the detective finds clues to the Ice Truck Killer's identity, but Angel fights Brian off and survives. When Dexter discovers that Brian is the one who stabbed Angel, he realizes that Brian is the Ice Truck Killer. Brian kidnaps Debra and leads Dexter to their old family home, where he reveals his true identity, their relationship as brothers, and the truth of their past. He tries to convince Dexter to join him in killing Debra, thus leaving his old life behind and starting a new life with his real brother, but Dexter stops hi

transports him to Brian's apartment, where he suspends him in the air, just as Brian did to his victims as the Ice Truck Killer. Brian tries to convince Dexter to set him free, telling his brother he can be free to be his true self with him. A frustrated Dexter loudly dismisses this, causing a single tear to run out of Brian's eyes. Dexter says he can't let Brian live because he knows he will always want to kill Debra. Brian continues to lecture Dexter on how he's being irrational and choosing to live a lie for people who will never really know or care about his real-self, instead of embracing his family who is just like him and accepts him for who he is, without apology. Dexter is tempted, but ultimately slices Brian's throat, telling him he can't hear anymore, while admitting Brian is right.
2013-08-21 0302

Dexter, grief-stricken, just as he slices Brian's throat.

Dexter convinces the police that Brian committed suicide in the same way he committed his crimes; forensic evidence even supports this theory as the cut on his throat becomes notably less tight as it nears the end, which is assessed as the result of Brian dying as he inflicted the wound rather than Dexter's own reluctance at what he is doing. Dexter is the only person to mourn his brother's death and he is the first victim that he does not take a souvenir blood sample from (that is, after he started with Alex Timmons), since he is the first victim he wishes he could have set free and in all reality, did set him free (through death).

Season Two


After killing his brother, the one person who understands and accepts him, Dexter find himself in a rare state of mourning, so much so that he is unable to kill one person, and botches the kill of another target.

Letting Go

Brian is seen only briefly (or referred to) in Season two, being a part of the plot in It's Alive! and Waiting to Exhale, respectively). Dexter comes to the realization that he cannot forgive himself or be able to kill again until he gets rid of reminders of his brother. This includes the barbie doll head that Brian left in Dexter's freezer. As Dexter drops it into the water from his boat, it seemingly transforms into Brian who latches onto Dexter's hand. However, Dexter lets go and Brian sinks back into the depths of the water, figuratively submerging the memories and influence of Brian.

Season Four

Debra's Discovery

His former love Debra Morgan begins an investigation into the past of the Ice Truck Killer She learns of Laura Moser and through extensive research, finally discovers the truth about Dexter's relation to Brian as his actual biological brother. She confronts him about this, informing him of this information while also realizing that Brian was using her just to get to Dexter. The matter is never spoken of again following the Trinity Case, although Brian is often mentioned in Dexter's thinking in relation to events where he deals with someone's brother, and other characters often refer back to the case through the series. In Season Seven, Debra connects the method that Dexter used to kill Travis Marshall to the same way that she was wrapped in plastic on Brian's kill table.This leads to her discovering that Dexter is the Bay Harbor Butcher.

Season Six

Stolen Evidence

For the most part, the Ice Truck Killer case had been buried. That is until a new intern in the Miami Metro Homicide forensics department came on scene, the beautiful young Ryan Chambers. In getting close to Vince Masuka, he eventually brought up the evidence from the Ice Truck Killer case for her to look through as sort of a gift. She expressed her fascination with the case, having followed it since the details were made public and that she even painted her fingernails to match the coloring that Brian used on his victims. The mannequin arm left in the evidence box was later stolen by her as a purpose of selling it on the internet. Brian was later mentioned again when Dexter saw Nathan's body during the "Four Horses of Apocalypse" crime scene, cut into separate parts similar to Brian's M.O. Masuka's requested his new intern Louis Greene to find a way to get the prosthetic arm back, unfortunately it was too late to get it back (in reality, Louis was the one who bought it). However he was able to erase all traces of it being on sale in the auction as well as any evidence linking the department, and with the Ice-Truck Case being frozen, all seems to be fine. Or so Masuka thought...

The Dark Passenger


Brian makes his long-awaited return

At the end of Just Let Go, he is seen clapping his hands after Dexter drowns Nick for the murder of Brother Sam. When Dexter comes back on the shore, he asks, "Hey, little brother. Miss me?"

During Nebraska, he talks Dexter into going to Nebraska.

TV Appearances

The following is a list of episodes that Brian Moser has appeared in.

Season One

Season Two

Season Six

In the novels

Main article: Brian

In Darkly Dreaming Dexter (unlike in the TV series), Brian does not use the name Rudy Cooper and does not get romantically involved with Deborah. He is noted as having a very strong resemblance to Dexter, to the point that upon seeing an image of Brian with dismembered corpses, Dexter and Deborah are convinced that Dexter is the murderer of the novel. The only physical differences noted by Dexter when they meet are that Brian is an inch or two taller, thicker through the shoulders and chest, and paler. He first meets Dexter face-to-face in a shipping container located in the same place as the one where their mother was murdered, with Deborah tied up and ready for Dexter to kill. Rather than killing either Deborah or Brian, Dexter lets him go. Their professions differ as well; the books have Brian working with imports, while the series has him as a prosthetic surgeon. The age gap between Brian and Dexter is noted as being only 1 year in the book. In the books he is known as the Tamiami Slasher.

Brian returns in Dexter is Delicious after learning of the birth of Dexter's daughter. He introduces himself to Dexter's family, and he worked for the cannibalist coven that would later lure Dexter, Deborah and Kyle Chutsky into a trap, later saving them from the cannibals.

In Double Dexter Brian still shows up for the weekly Friday dinners at the Morgan/Bennet household, while he works with real estate. He also helps Dexter removing a problem.
