Show: 'Dexter'



Arthur Mitchell is an unassuming suburbanite and family man — who for 30 years has been living a double life as a serial killer. Frank Lundy dubs him the "Trinity Killer" because of a recurring pattern of three killings. First, Mitchell would kill a young woman in a bathtub by slicing her femoral artery with a straight razor while putting her in a choke hold, and holding up a small mirror so that he can see her face as she dies. His second victim is a married mother of two, whom he kidnaps and forces to jump to her death from an abandoned building. His third victim is a father of two, whom he bludgeons to death with a hammer. At each site he places a small sample of his sister's ashes, and arranges the victim's arm to point at the ash. He has repeated this cycle in different cities all over the United States.

Arthur would use a 'Four Walls Build' to cover his killings, and bury his first victim under the house being built.
