David Ronald Hart was 31 when he was last seen on the morning of Friday, September 24, 1993. His mother gave him a ride to the corner of Route 18 and Walker Lane in South Franklin Township, Pennsylvania, and he was headed to a local masonry job that he reportedly completed later that day. He received his paycheck, but someone else cashed it. After that, he was never seen or heard from again.

David was dressed in blue jeans, a dark-colored shirt, work boots and wore glasses. He had brown long hair, blue eyes, a mustache and a tattoo on his right arm. He had a history of alcohol and drug use and had disappeared briefly before, but he always stayed in contact with family; this time he did not, and his family reported him missing on November 5, 1993. He had been planning to move into a new apartment and had applied for a state job, which family say made a voluntary disappearance unlikely.

Investigators tracked several unverified leads: a possible sighting at a Green Street bar in Canton Township the weekend he vanished, a tip he might be buried in state game lands that produced no evidence, and an acquaintance who turned in his wallet two months later with a concert ticket stub suggesting attendance at the Starlake Amphitheatre. The Pennsylvania State Police continue to seek information. Does anyone who knew David or remembers seeing him in late September 1993 have information to share?
