Mike Groll/AP/Shutterstock The story of the Son of Sam, David Berkowitz, who was found guilty of six murders committed in New York City in the late 1970s, once again returns to prime time in Netflix’s new documentary The Sons of Sam. Though Berkowitz is the titular focus, the four-part series organizes events around a different Yonkers resident. The series chronicles the white-whale search of investigative reporter Maury Terry, who maintained Berkowitz was not the sole perpetrator of the New York City killing spree. His investigations and his book, The Ultimate Evil, attempted to connect Berkowitz’s crimes to other occult-linked killings in the United States, while also proving the Berkowitz murders required accomplices—namely Berkowitz’s neighbors John and Michael Carr, the actual sons of Sam (Sam Carr).
