The cops never found him but told her in all likelihood it was the Zodiac killer and that she was a very lucky girl.
I remember there was a young girl picked up by the Night Stalker (or was it the Hillside Strangler - one of the serial killers of the 1980s in L.A.), and he had her captive in his car and went looking through her wallet. She had a photo of the actor Peter Lorre in her wallet because he was her grandfather. When the killer asked her about it and she said it was her grandfather, he threw her out of the car.
Her late grandfather saved her life.
