Kenney was last seen at the Quality Convenience Store on Business 71 Highway in Nevada, Missouri on the evening of February 27, 1991. She usually worked until midnight, but it was a slow night and she evidently decided to close the store early. Her time card shows she clocked out of work at 10:00 p.m. She never arrived home and has never been heard from again. Her vehicle was later found abandoned in the store parking lot. The store's janitor left a few minutes before Kenney closed up. He stated there weren't any customers' cars in the parking lot when he left, but there was a male customer inside the store whom he didn't recognize. The customer hasn't been identified and it's unclear whether he had anything to do with Kenney's disappearance. Two witnesses in the area reported hearing a woman scream right around the time Kenney would have gone out to her car. Her case remains unsolved.
