Shirley Anne Gladney, 20, of Okolona, Mississippi, went missing after leaving her home on foot on April 9, 1999. She was said to be walking to pay an electric bill and never returned; her family reported her missing on April 12. At the time she disappeared Shirley was 5 feet 7 inches, about 125 pounds, with medium-length black hair and brown eyes. She was last seen wearing a white t-shirt and blue jeans.

Very few details have emerged since 1999 and investigators report no significant leads. Authorities have not announced developments, and the case remains unsolved more than two decades later. If anyone has information about Shirley’s movements on April 9, 1999, or saw her in Okolona that day, please contact the Chickasaw County Sheriff’s Department.
