A Placentia family missing since Saturday turned up in Lone Pine looking "tired, dirty and hungry," but apparently unhurt. Computer consultant Floyd Braun, 41, telephoned the Inyo County Sheriff's Department to report that the family had been stuck in the desert and needed help, said Lt. Bill Lutze. The Brauns had pulled off U.S. 395 Wednesday night to spend the night in the desert south of Lone Pine, and the car somehow got stuck, Lutze said. The Brauns "were very vague about it, and they (sheriff's investigators) haven't found (the) car yet. "The family had no destination," Lutze said. " . . . They were not kidnaped or coerced. They had just walked into town today, went to a local market, and called us for help. We picked them up. They looked tired, dirty and hungry."
