In the 1970s and early 1980s, Kraft, a bland-looking computer consultant with an IQ of 129, picked up hitchhikers and plied them with drugged beer, so that he could torture, sexually abuse and kill them, before dumping their bodies on freeway ramps.
He was caught when he was stopped by California Highway Patrol officers on a freeway in 1983. Inside Kraft's Toyota, the officers discovered a dying young Marine, a hitchhiker whom Kraft had picked up and drugged.
Also in his car, investigators found what apparently was a coded list of victims. At his Long Beach home, they further discovered snapshots that he had taken of them, and a collection of their possessions — trophies of his murders.
At Kraft's trial, his lawyers unsuccessfully argued that his violent acts were caused by brain damage. In 1989, he was convicted by a jury of 16 murders, and after prosecutors introduced evidence that he had killed as many as 65 men, he was sentenced to death. Decades later, Kraft is still on death row in San Quentin, as his case makes its way through the appeals process [source: Hicks, Kiger].
