5 (in season 4)
Modus Operandi
Large knife, Etorphine (M99), Garrotting wire. Occasionally a cordless drill, hammer and chainsaw, set of scalpels and other surgical equipment.
Killing Method
Dexter first sedates his victims with M99, wraps them up, ties them down and stabs them in the heart (specifically the left ventricle). He has been known to alter his method for certain victims, for example he kills Arthur Mitchell with the same hammer Mitchell used to kill one of his victims.
Method of Disposal
Bodies are subjected to post-mortem dismemberment. The severed pieces are then put in biodegradable bin liners and dumped in the Atlantic Ocean via the Gulf Stream, where they are carried throughout the country until deposited in the North Atlantic.
Dexter (along with his brother Brian) witnessed the brutal murder of their mother in a cargo container at a very early age. After seeing Laura Moser chainsawed to pieces, they were then left in the cargo container for three days.

Dexter Morgan is the protagonist of both the DEXTER television series and the Dexter Book Series. Dexter is a blood spatter analyst who happens to hobby in being a Serial killer. He has an adoptive sister by the name of Debra Morgan and the former biological brother of the deceased Brian Moser. His adoptive parents are Harry and Doris Morgan, unfortunately both have passed away prior to the events of this season.

After the events of Season Three, Dexter is now married to his wife Rita Morgan where they've had a son named Harrison Morgan, in addition to Dexter's stepchildren Astor and Cody. Dexter has officially moved in with Rita at her house and thus live a suburban life where he goes to work each day while coming home to provide for his family. Needless to say, his "hobby" of being a Serial killer has become more difficult to sustain now that he's a husband and father to a young baby, thus the desire to figure out how he can survive the years to come goes into question and he seeks this assistance from a man named Arthur Mitchell, a Serial killer also known as Trinity whom has survived (with a family) for over Thirty Years.



Introducing Harrison Morgan and Arthur MitchellEdit

Harrison MorganEdit

Dexter is shown driving around Miami, as he was seen in the first episode. He stops in front of a house, which has not been seen before by the viewers, and then steps out. A few steps away from the car, and the cries of a baby are heard from the back of the car. Dexter goes back, and opens the back seat, revealing a child around three months old. This child is the same one Rita was pregnant with the entire third season, Harrison.

Arthur MitchellEdit

"It's already over"Edit

After killing Arthur, Dexter returns home, intending to meet up with Rita later on. However, upon arriving home, he finds a message from her, on his phone. The message reveals that she forgot her passport at home, and had to return for it. After hearing the message, he calls her back, only to hear her phone ringing nearby.

From the bathroom, Harrison is heard crying, and Dexter rushes to help his son. When he gets into the bathroom, he sees a familiar scene: That of a child sitting in the blood of its mother. He picks up his child, and then walks away from the scene, realizing that "It doesn't matter what I do... what I choose... I'm what's wrong".
