The Hillside Strangler, later the Hillside Stranglers, is the media epithet for a serial killer who terrorized Los Angeles between October 1977 and February 1978, with the nickname originating from the fact that many of the victims' bodies were discovered on the sides of the Hollywood Hills. The police, however, knew because of the presence of multiple distinct DNA traces and the positions of the bodies that two individuals were killing together, but withheld this information from the press. These two individuals were discovered to be cousins Kenneth Bianchi and Angelo Buono, who were later convicted of kidnapping, raping, torturing, and murdering ten females, ranging in age from twelve to twenty-eight years old.
