Doris Jean Stalker, 54, vanished from a supermarket parking lot in Emlenton, Pennsylvania, on the evening of November 28, 1983. She and her husband had driven from Mariasville after a pharmacy was closed; at about 8:00 PM he went into the Super Duper Market and returned six or seven minutes later to find the passenger door open and Doris gone. Her purse remained in the car.

A large search began the next day. State police, volunteer firefighters and bloodhounds combed the area around the supermarket, and scuba divers searched the nearby Allegheny River, but no trace of Doris was found. She was described as a white female, brown hair and brown eyes, 5 feet tall and 100 pounds, last seen wearing blue jeans, a three-quarter length imitation brown leather coat and brown suede shoes; she was wearing a diamond ring, a wide wedding band and a birthstone ring.

The abrupt disappearance, with personal belongings left behind and no witnesses or physical evidence reported, left investigators and the family with unresolved questions. Does anyone in the Venango County area remember seeing Doris that night or have information that could help explain what happened?
