Jennings Hart disappeared sometime after 3pm on Monday, January, 21, 1980. He was last seen at a gas station in Marienville, where he purchased gasoline for his car. When state police received a call that Mr Hart was missing, they went to his home, located in a heavily wooded area along Rte 899, south of Marienville. There they found his car in the garage, the car keys in the house, and change scattered in the driveway. Initially, it was thought that Mr Hart may have gotten lost in the woods while walking his dogs, but police later learned that he had recently sold the dogs. State Police organized a search the weekend after Mr Hart disappeared. About 50 volunteers conducted a foot search in the woods surrounding Mr Hart's home, but no trace of him was found. Bloodhounds were brought in, but they failed to pick up his scent. Foul play is strongly suspected in Jennings Hart's disappearance, but his body has never been found.
