Jim Sullivan
A local musician in Malibu, California, he released an album called U.F.O in 1969. Despite his popularity, he never made it big. He did get an offer from a producer from Nashville, who told him to drive out there.
So with his guitar in hand, $120 in his pocket, he got into his truck and drove away, leaving his wife and son. His truck was found abandoned in New Mexico, with the guitar still in the back.
Even more chilling, is that his album U.F.O was about a man who drives off into the desert, leaving his family behind, and getting abducted by aliens.
