Lisa Marie Waddle, 46, of Burkburnett, Texas, was found shot to death on April 8, 2015, at a vacant farmhouse west of Quanah. She was one of two victims; 41-year-old Terrance Besaw of Chillicothe was also found shot at the scene.

Authorities arrested 31-year-old Gary Andrew Callaway of Quanah several days after the bodies were discovered at a Wichita Falls motel on an outstanding credit card abuse warrant. He was charged with two counts of capital murder. Prosecutors presented physical evidence and a confession in which Callaway said he shot Besaw in self-defense and admitted killing Waddle because he believed she would be a witness.

A jury of seven men and five women convicted Callaway, and in June 2016 he was sentenced to life in prison. The families of Waddle and Besaw were left to grieve after the verdict.
