Or maybe William Bonin... he was around in that time also
https://en.wikipedia.org/wiki/William_Bonin
Two years after his arrival at the Atascadero State Hospital, Bonin was sent to prison, declared unsuitable for further treatmentlargely due to his repeatedly engaging in forceful sexual activity with male inmates.[28] On June 11, 1974, he was released from prison after doctors concluded he was "no longer a danger to the health and safety of others."[27]
Further offenses and imprisonment[edit]
On September 8, 1975, Bonin encountered a 14-year-old named David McVicker[29] hitchhiking in Garden Grove; McVicker accepted Bonin's offer to drive him to his parents' home in Huntington Beach; shortly after McVicker had entered Bonin's vehicle, he was taken aback by Bonin asking him if he was gay. When McVicker asked Bonin to stop his car, Bonin produced a gun and drove the youth to a deserted field, where he ordered McVicker to undress, then beat and raped him.[30] After beating and assaulting McVicker, Bonin began to strangle the youth with his own T-shirt, then immediately became apologetic when McVicker began screaming. He then drove McVicker home before casually stating, "We'll meet again."[31]

I've wondered if Larry Dean Williams might have been a Randy Kraft victim.

He was known to be a frequent hitchhiker. Kraft operated in the Long Beach/Orange County areas and many of his victims were hitchhikers.
