Dexter (episode)
Dexter is contacted by his foster sister Debra (Jennifer Carpenter), a vice officer in the Miami Metro Police Department. Dexter, a blood spatter analyst for the department, assists Debra in investigating an apparent serial killer targeting prostitutes. Dexter examines the latest victim and is shocked to find no trace of blood on the dismembered corpse. At the police station, Dexter discusses another murder case being handled by James Doakes (Erik King), a detective who dislikes him. Later, Dexter watches Jamie Jaworski, a murderer who escaped justice due to a faulty warrant, and breaks into his home to find evidence. Once he confirms that Jaworski is guilty, Dexter meets with his girlfriend Rita Bennett (Julie Benz), a former victim of domestic abuse victim; Rita has two young children, Astor and Cody. While on a date with Rita, Dexter finds another murder scene with no traces of blood, this time with the victim's head missing. Dexter theorizes that the killer murders his victims in extreme cold, explaining the absence of blood, and might be using a stolen refrigerated truck. Dexter allows Debra to pitch the theory, but their superior officer, Lt. María LaGuerta (Lauren Vélez), dismisses it.
Dexter (TV series)
Orphaned at age three, when his mother was brutally murdered by a man with a chainsaw, and harboring a traumatic secret, Dexter (Michael C. Hall) was adopted by Miami policeman Harry Morgan (James Remar), who recognized the boy's homicidal, sociopathic tendencies and taught him to channel his gruesome passion for killing in a "constructive" way—by killing only heinous criminals (such as child molesters, mob assassins, rapists, serial killers of the innocent, etc.) who had slipped through the justice system. To satisfy his interest in blood and to facilitate his own crimes, Dexter works as a forensic technician specializing in blood spatter pattern analysis, for the Miami Metro Police Department (based on the real-life Miami-Dade Police Department). Although his drive to kill is unflinching, he is able to simulate, and in some cases feel, normal emotions and maintain his appearance as a socially responsible human being. Dexter is extremely cautious in his kills – e.g., he wears gloves and uses plastic-wrapped kill rooms, carefully cleans up afterward, segments the bodies and disposes of them in the ocean – to reduce the chances of detection.
