Lisa Michele Smith was 17 when she disappeared after hitchhiking in Santa Rosa, California, on March 16, 1971. She was living in foster care and was reported missing by her foster parents and her boyfriend. The last known sighting placed her at about 7:00 PM on Hearn Avenue wearing a white ruffled blouse, a dark pea coat, green bell-bottom jeans, and cowboy boots.

On March 26, 1971, a young woman fitting Lisa’s description was involved in a traumatic incident on Highway 37 near the Petaluma River. She reportedly jumped from a moving red-and-white late-model Ford truck going about 55 miles per hour after saying the driver had assaulted her and demanded sex. Hospital staff estimated the woman’s age at about 21; she identified herself as Lisa Smith but gave few details.

Reports conflict about what happened next. No confirmed arrests, suspects, or litigation have been publicly linked to her disappearance, and her fate remains uncertain. Did anyone in the Santa Rosa or Livermore area know Lisa or see her in March 1971?
