William Bonin

William George Bonin (January 8, 1947 – February 23, 1996) was an American serial killer and twice-paroled sex offender, who committed the rape, torture and murder of a minimum of 21 boys and young men in a series of killings between 1979 and 1980 in southern California. He is sometimes referred to as "The Freeway Killer", a nickname he shares with two other – separate – serial killers, Patrick Kearney and Randy Steven Kraft. Bonin is also suspected of committing a further fifteen murders. He was convicted of 14 of these murders and subsequently executed in 1996.

Bonin became known as the Freeway Killer due to the fact that the majority of his victims' bodies were discovered alongside numerous freeways in southern California.
