The Code of Harry

He is a 'gentle' killer. He is a 'blood' expert investigating the murders in Miami. He kills to bring justice to the world. His name is Dexter, and his goal is to survive in his personal view of the justice of his cult.
Dexter Morgan, who draws a photo of both a competent serial killer and a social person, has been erasing bad guys from the face of the earth since 2006 according to his own morality.

Brian Moser, along with his brother Dexter, was sent to a mental hospital after their mother was killed in front of their eyes, and he remained estranged from his brother. He killed 9 prostitutes and no blood was found on any of their bodies. Miami Metro Police officers named him the "Ice Truck Killer", thinking that the blood was frozen in the ice truck.
