Michael John Nangle, 37, was last seen in San Francisco on September 26, 1995. His rental car was found abandoned on the Golden Gate Bridge, with footprints leading from the vehicle to the bridge’s railing. A U.S. Coast Guard search turned up no sign of him and he has not been heard from since.

The circumstances are classified as suspicious because of the location and the possibility of a jump from the bridge, a scenario sometimes associated with suicides there, but no conclusive evidence has been reported and investigators have not recovered his body. Despite being entered in missing persons databases and searches at the time, no substantial leads have emerged.

If anyone saw Michael, knew where he was headed that day, or has information about the footprints or the car on the bridge, please come forward.
