Leslie Gale Mears, 52, disappeared from Tulsa, Oklahoma, after leaving work on the afternoon of June 28, 2010. She finished her shift at 4:30 p.m., called her employer afterward to say she would not be back the next day because of a family emergency, and that call is the last confirmed contact with her.

Her parents reported her missing when they could not reach her. The Tulsa Police Department opened an investigation that later became a cold case. Investigators at one point followed a tip that she might be in Florida, but that lead did not locate her. No arrests or publicly identified suspects have been announced and her whereabouts remain unknown.

If anyone knew Leslie’s routines, movements on June 28, 2010, or has information about the Florida lead, please come forward.
