Michael Lawrence Mondini, 22 and living on 22nd Street in San Francisco, was last seen on December 31, 1979. The circumstances of his disappearance are unclear: after that date no confirmed sightings or communications were reported and the family’s efforts to find him have produced very little verifiable information.

Accounts of when he was last heard from conflict. Some relatives recall a last contact in early January 1985 when Michael reportedly said he had taken a job with a chemical company, although he had no known background in that field. A friend later said Michael’s motor scooter was found abandoned at the San Francisco Airport. In the mid-1990s there were possible indications he might be alive, but those leads were likely the result of a family member mistakenly using his Social Security number rather than actual sightings.

The case remains unsolved and the family continues to seek answers. If anyone has information about Michael’s movements around 1979–1985 or about the scooter found at the airport, please share what is known.
