David Berkowitz is an American serial killer who terrorized New York City from July 1976 to July 1977. Over the course of his crimes, he wounded 7 people and murdered 6 people. His typical pattern involved targeting couples that were parked in cars and shooting them with a .44 caliber pistol. He became known as the "Son of Sam" after leaving a letter at one of his crime scenes that stated:

"I am the "Son of Sam." I am a little "brat". When father Sam gets drunk he gets mean. He beats his family. Sometimes he ties me up to the back of the house. Other times he locks me in the garage. Sam loves to drink blood. "Go out and kill" commands father Sam."

Berkowitz came under suspicion when his car was ticketed for being parked too close to a fire hydrant at the scene of one of the Son of Sam shootings around the time the shooting happened. When police tracked down the car they found it parked outside of Berkowitz's apartment building in Yonkers with a gun in the back seat. They searched the vehicle and found ammunition, maps of the crime scenes, and a threatening letter to police. This evidence was enough for them to arrest Berkowitz for the Son of Sam murders.

On Aug. 10, 1977, Berkowitz exited the apartment building and sat in the drivers seat of his car. After sitting in the front seat, the two police officers that were staking out the car arrested Berkowitz. Berkowitz immediately confessed to being "Sam", and said "Well, you got me." Investigators described the inside of Berkowitz's apartment as "a typical bachelor pad", messy without sheets on the bed. After being arrested, Berkowitz confessed to all of the shootings and ultimately pled guilty in court. He was sentenced to 25-years-to-life in prison for each murder, to be served consecutively. He remains incarcerated at the Shawangunk Correctional Facility in New York.
