Lisa Michele Smith, a 17-year-old girl, disappeared on March 16, 1971, after hitchhiking in Santa Rosa, California. She had been living in foster care and was reported missing by her foster parents and boyfriend. The last known sighting of Lisa was along Hearn Avenue at approximately 7:00 PM, where she was seen wearing a white blouse with ruffles, a dark pea coat, green bell-bottom jeans, and cowboy boots.
Authorities initially labeled her as a runaway, despite there being no clear reason for her disappearance.
Nearly two weeks later, on March 26, 1971, a young woman matching Lisa's description was involved in a traumatic incident on Highway 37, near the Petaluma River. She reportedly leaped from a moving vehicle traveling at approximately 55 miles per hour, sustaining a skull fracture and multiple severe abrasions. The woman identified herself as 'Lisa Smith' and claimed she had been hitchhiking from San Francisco to Sausalito. She alleged that the driver of the red-and-white late-model Ford truck had assaulted her and demanded sex in exchange for a ride. In an act of desperation, she jumped from the vehicle to escape.
Hospital staff estimated that the woman appeared to be around 21 years old, though she provided little specific information about herself. Authorities began linking her case to the missing 17-year-old Lisa Michele Smith, and local newspapers reported that they were the same person. However, conflicting reports emerged regarding Lisa's whereabouts after the hospital incident. Some sources suggested that she had been found by her birth parents and taken to a different hospital before returning to their home in Livermore. Others speculated that this information was a hoax, as a 2011 article stated that Lisa was still missing, with authorities seeking public assistance.
The case remains shrouded in uncertainty, with lingering questions about Lisa's fate and whether she was a victim of the Santa Rosa Hitchhiker Murders. No confirmed arrests, suspects, or litigations have been publicly linked to her disappearance or alleged assault. The mystery surrounding Lisa Michele Smith continues to perplex investigators and those who seek answers about her tragic story.
