In the Netflix docuseries, “Conversations With a Killer: The Son of Sam Tapes” (now streaming), director/ producer Joe Berlinger explores David Berkowitz and his reign of terror on 1970s New York City — and even includes the killer’s claim that he wasn’t the culprit who shot one of his surviving victims, Wendy Savino.

The serial killer’s voice in previously unreleased 1980 recordings provides the hook to director Joe Berlinger’s documentary, which also offers interviews with detectives, survivors and others connected to or obsessed with the case.

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.
