Melissa Sue Flores, 27, disappeared from Cordell, Oklahoma, after being last seen on January 27, 2007, at the home of her ex-boyfriend, Ronnie Denny Jr. She had called her sister-in-law that morning saying she was on her way to pick up her children but never arrived. Her car was later found at Denny’s residence with her purse and cell phone inside.

Melissa was the mother of three and had a history of a volatile relationship with Denny; she had sought a protective order against him months before her disappearance but later asked that it be dismissed. Years passed with no sign of her. A childhood friend of Denny’s, Jason Canterberry, later said Denny confessed to shooting Melissa with a rifle during an argument, and that testimony became central to the case.

A grand jury indicted Ronnie Denny Jr. for first-degree murder in 2014, and a jury convicted him in 2015. No body has been found and searches have not located Melissa’s remains. Anyone with information about where Melissa might be should contact the Oklahoma State Bureau of Investigation.
