David Berkowitz, also known as the Son of Sam, killed six people and injured a number of others during his 13-month shooting spree in 1976 and 1977. Here is everything to know about the survivors of Berkowitz’s attacks.

Berkowitz, who is now 72, is currently incarcerated at the Shawangunk Correctional Facility in Ulster County, New York. He was found guilty of six counts of second degree murder and seven counts of attempted second degree murder in 1978 and sentenced to 25-years-to-life in prison for each murder.

Why was David Berkowitz called "Son of Sam"? Unlike most serial killers, Berkowitz bestowed this nickname upon himself. Its origin is certainly odd.
