David Berkowitz, known as the "Son of Sam", was an American serial killer who terrorized New York City from 1976-1977. He killed 6 people and wounded 7 others, claiming a demon possessed his neighbor's dog and commanded him to kill. Berkowitz targeted young couples, often blondes, shooting the women fatally but wounding the men. He became known as the ".44 Caliber Killer" and left taunting letters and notes at crime scenes to taunt the police. Berkowitz was eventually caught after receiving a parking ticket near one of his crime scenes.
