Patrick Wayne Kearney (born September 24, 1939) is an American serial killer who preyed on young men in California during the 1970s. He is sometimes referred to as 'The Freeway Killer', a nickname he shares with two other separate serial killers, William Bonin and Randy Steven Kraft. Patrick Kearney is possibly among the most prolific serial killers in United States history, claiming possibly as many as 43 victims according to law enforcement. He was the youngest of three sons and was raised in a reasonably stable family. His early life was not without some trauma, however; as a thin and sickly child, he was often a target for bullies at school. In his teens, he became withdrawn and fantasized about killing people. Born in East Los Angeles, Kearney also lived in Texas. Kearney moved back to California after a brief marriage ended in divorce, and eventually worked as an engineer for Hughes Aircraft.
