Hilary Harmon Stagg Jr., known to some as Bill or Billy, disappeared from Baton Rouge, Louisiana, in November 1977 at age 23. He was 6 feet 3 inches, slender, with brown hair. The exact date in November is unclear.

His abandoned car was found parked on the west side of the new Mississippi River bridge. Inside were his wallet and a suicide note, which led authorities to conclude he likely jumped from the bridge into the river. No body was ever recovered. A passerby that same day reported seeing a young man walking away from the bridge at the Plaquemine exit, but it is not known whether that person was Hilary.

Hilary remains classified as a missing person; the presence of a note points toward suicide but the lack of a recovery leaves uncertainty. Does anyone have memories of Hilary or information about his movements in Baton Rouge that November?
