Summary based on the NamUs case record (MP11083) and 5 other sources
Allister Mackenzie, aged 35, disappeared from Mill Valley, California, on October 3, 1977. He left his home and was never seen again. His car was later found abandoned on the Golden Gate Bridge in San Francisco, which raised concerns that he may have taken his own life, as the bridge is known for such incidents. However, no definitive evidence has surfaced regarding his fate.

Mackenzie's case remains unsolved after several decades. Despite the mysterious circumstances of his car being located on the bridge, authorities have not uncovered substantial leads, and his whereabouts are still unknown. His disappearance is classified as endangered, and the investigation remains open, with the public encouraged to provide any tips that could help resolve the case.
