David Berkowitz (born June 1, 1953), also known as the Son of Sam and the .44 Caliber Killer is an American convicted serial killer who terrorized New York for a year. He would roam the streets in search of victims. He would send letters to the police telling them about his crimes. He described himself as an evil demon and called himself the Son of Sam. He killed 6 people and wounded 7. He was caught and tried in New York where he said demons told him to do it. In 1993, he claimed a cult did some of the murders but most people who worked with him find this story unbelievable.
