Dennis W. Duhart was 21 when he left his parents’ St. Louis home at about 4:40 a.m. on November 13, 1996, apparently heading for a shift at Target. He never arrived. At about 7:00 a.m. that morning his black 1996 Pontiac Grand Am was found abandoned and locked on the shoulder of the westbound lane of the Jefferson Barracks Bridge.

He also left his credit cards and about $70 in cash. Searches of the river near the bridge turned up nothing. His parents later received repeated hang-up calls from a blocked number from shortly after Christmas 1996 through the summer of 1997 that they believed were from him. Coworkers mentioned a girlfriend at the University of Missouri, but the family could not confirm her existence.

What details might someone in the area from that time remember that could help explain why Dennis’s car was left on the Jefferson Barracks Bridge?
