Darling was last seen at the Choctaw Casino and Resort in Grant, Oklahoma, at approximately 1:30 a.m. on June 10, 2011. She left the casino with Jeremy Blake Upchurch and has not been seen or heard from since. Her vehicle, a black 2010 Ford Sport Trac with Texas license plate AW4-8951, was discovered abandoned a few days later near Hugo Lake, Oklahoma. The vehicle was locked and had two flat tires. Upchurch has been named a person of interest in her disappearance. Authorities suspect foul play, and Darling’s case remains unsolved. She left behind two children.
