Doris Stalker, of Hilliards, PA, Washington Township, Butler County, was last seen on Monday, November 28, 1983 in the parking lot of an Emlenton, PA supermarket. Mrs. Stalker and her husband had reportedly driven to a pharmacy in Mariasville, PA to have a prescription filled but found that the pharmacy was closed. They then rode over to the (former) Super Duper market in Emlenton, PA. Mr. Stalker went into the store while Doris waited in the car. Mr. Stalker said that he was only gone for six or seven minutes. When he returned to the car, at around 8:00 PM, the passenger side door of the car was open, and Doris was gone. Her purse was still in the car. The following day, state police, volunteer firefighters and bloodhounds searched the area around the supermarket and scuba divers searched the nearby Allegheny River, but no trace of Doris was found.
