In a statement to CBS 11 News, Bevers’ husband, Brandon Bevers, expressed gratitude for the increased reward, saying: “We are extremely pleased with the additional reward money, and pray the notion that an individual with any knowledge surrounding the individual responsible for Missy’s murder will come forward to receive this money.”

Anyone with information can contact the tip line at 972-775-7624. Tipsters can also remain anonymous by contacting Ellis County Crime Stoppers at 972-937-PAYS (7297). 

Midlothian Police said last week, they have brought in a ‘new set of eyes’ to look at the case from a fresh perspective.

Experienced homicide detectives from other departments and agencies are reviewing the Bevers case and trying to help put together pieces of the mystery.

It was on April 18, 2016 that Bevers was found murdered inside the Creekside Church of Christ. She had gone to the church in the early morning hours to set up for a Camp Gladiator workout class.

Surveillance video shows a suspect with a distinctive walk, dressed in police tactical gear, inside the church before Bevers arrived.
