In 1986, a twenty-year-old San Diego State University student named Cara Knott was pulled over by a California Highway Patrol officer on a dark, isolated off-ramp along Interstate 15. It was the same spot he’d chosen for making creepy overtures to other women drivers. When she resisted his advances, the officer grew enraged, strangling her with a rope and heaving her body off an abandoned bridge. Cara Knott had been Dave Holmes’s babysitter.
