The Trinity Killer

The Trinity Case is a police investigation into cycles of killings. Each one was found to consist of a ten-year-old boy encased in cement, a young single woman killed in her own bathtub, a mother of two forced to jump from a tall building, and a forty-year-old father of two beaten to death.

This case is the sixth major case in the series. The major case preceding this one is the Lundy Shooting and the next major case after this is the Santa Muerte Case.

History of Killer

When Arthur Mitchell was ten years old, he accidentally startled his sister, Vera Mitchell, as she took a shower, causing her to fall, slice her femoral artery, and bleed to death. After this event, Marsha, his mother, fell into a deep depression and his father, Henry, began to drink heavily and exhibit abusive behavior. Arthur's mother eventually committed suicide by jumping off a bridge. After she died, Henry became even more abusive towards his son, blaming him for his sister and mother's deaths. One night, Henry was beaten to death outside a bar, and Dexter suspected that Arthur was the one who had killed him.

Summary

Arthur returned to his original murder sites and completed another kill cycle. He sliced the femoral artery of a young woman in her bathtub, after which he took a scalding hot shower. For his next murder, he forced a mother of two to fall to her death. He then provoked a drunken man into beating him up, after which he bludgeoned another man to death. After each kill, Trinity placed a smudge of his dead sister's ashes near the victim. Later, a fourth victim was discovered -- a ten-year-old boy buried in cement prior to the other three victims .Although he was retired from the FBI, Frank Lundy returned to Miami to hunt down Trinity. In "Blinded by the Light," Lundy told Dexter that he had counted 15 kill cycles in the past 15 years. He acknowledged an additional 15 years dating back to the murder of Vicky Noonan in 1979.

Case Detectives

  • Detective Debra Morgan - Trinity was one of her top priority cases

Other operatives involved in the case:

Suspects

  • Eddie Noonan - Thirty years ago, he was the primary suspect in the murder of his wife Vicky. Although he was innocent, he was convicted of the murder and sent to prison. When Lisa Bell was murdered in his old house thirty years later in the same fashion, Debra Morgan interrogated him. Later, Eddie was exonerated for both murders when it was revealed that Arthur Mitchell had killed his wife.
  • Stanley "Stan" Beaudry - Stan had previously murdered a prostitute, but was released due to broken chain of custody for the murder weapon. Due to his criminal record and because Dexter had planted evidence against him, Stan was suspected as being The Trinity Killer. Later, he was cleared of suspicion when he was alibied for some of the murders.
  • Arthur Mitchell - He showed up on Homicide's radar when they learned that Trinity had killed a little boy. This led to the discovery of other boy burials around the country connected to Arthur's construction sites. He was confirmed as The Trinity Killer when his history of family deaths was revealed, and it matched his kill pattern.

Unsuspected Killer

  • Jonah Mitchell - He was the son of the real Trinity Killer. After his sister committed suicide (due to abuse by their mother), he lost his temper and killed his mother. He then set it up to look like his father was the murderer of both his sister and mother. Later, Jonah told Dexter what really happened ("Nebraska").

Kill Schedule

In November 2009, Debra Morgan discerned a pattern when she noticed that the murders were being committed in certain months. At this point, she had counted up to 75 individual killings. They included young women found bled out in bathtubs, mothers who had fallen to their deaths, and men that had been bludgeoned. On Thanksgiving Day, she realized that Trinity's kill schedule matched school breaks ("Hungry Man")

Kills Outside Cycle

  • Henry Mitchell - Arthur's father. Although it is never confirmed that Arthur killed him it is likely, as Arthur shouts verbal abuse to his later victims of bludgeoning. It is possible that Henry was Arthur's first kill.
  • Kyle Butler - A victim that Arthur bludgeoned while he was trying to find Dexter. It was done after he had failed at starting a new cycle. This man doesn't fit into Trinity's cycle because Arthur just wanted to kill him to silence him. Soon after, Arthur tracked down another Kyle Butler, but did not this one.
  • Rita Morgan - A bathtub victim. She is considered outside of his cycle for two reasons: He had yet to succeed in burying a young boy in cement, and, as a mother, she didn't fit the normal characteristics of his bathtub victims.

Indirect Deaths

  • Vera Mitchell - She accidentally died while taking a shower. She was startled when she noticed Arthur watching her and fell. She broke the shower door, cut her femoral artery, and bled out.
  • Sally Mitchell - She was angrily bludgeoned by Jonah Mitchell, after his sister committed suicide. Sally had continually blamed Jonah and Rebecca for the circumstances surrounding Arthur.

Attempted Victims

Alleged Victims

  • Frank Lundy - He was believed for some time to be a victim of Trinity, until it was confirmed that the person who shot him and Debra Morgan (she survived) was shorter than Trinity.
  • Rebecca Mitchell - She actually committed suicide in a bathtub, although Debra blamed Trinity,
  • Sally Mitchell - She was beaten to death by Jonah Mitchell, but Debra believed her to be a victim of Trinity.

Closure of Case

The FBI forced Miami Metro Homicide to turn the case over to them, after Trinity was identified as Arthur Mitchell.

Fate of Killer

Arthur Mitchell was assumed to be alive and in hiding. Eventually, Dexter revealed to Jonah Mitchell and Debra Morgan that he had killed Arthur.

    • If he's smart enough to kill for 30 years and still roam free I don't think finding the correct adress is too much for him.
