MIDLOTHIAN (CBSDFW.COM) – According to a search warrant obtained on Thursday, mother Missy Bevers died from a head wound Monday morning, when a suspect used an unknown instrument to strike her down. The fitness instructor’s body was discovered inside of Creekside Church in Midlothian.

Bevers was getting ready to lead a 5:00 a.m. boot camp class at the church. Authorities stated that the murderer broke into the building before Bevers arrived, assaulted the 45-year-old woman and left her unresponsive on the ground. Surveillance video shows the suspect wandering the halls of the church dressed head-to-toe in police SWAT gear. The killer had so much clothing on that authorities have not even been able to identify the individual’s gender.

The motive behind the attack remains unclear. Police first said that Bevers may have interrupted a burglary, but that has been called into question. Some clues have even indicated that this may have been a targeted attack. Bevers had advertised the date, time and location of her class online.

The woman’s family in Red Oak was worried about her safety during these early morning workout classes. She leaves behind a husband and three children.

Attorney and former police officer Pete Schulte said, “This is not your routine burglary. I don’t want to say anything’s routine but, if somebody’s going to try to go burglarize a business, they’re going to get in and get out and try to grab as much stuff as they can and then leave.” In the security video, the suspect is never seen taking anything from the church.

“Is it real yet? No, it’s not real yet,” stated husband Brandon Bevers, who asked for privacy during this hard time, and pleaded with the public to review the surveillance video and help him, and police, find the killer. He had gone on an annual fishing trip to Mississippi on Sunday night.

The husband could not think of a reason that anyone would have to harm his wife. “This world is full of evil people,” Brandon Bevers said. He does not believe that this was a targeted attack.

“We want to offer our heartfelt condolences to the family,” added Chief Carl Smith of the Midlothian Police Department. “This is a tragic event for all involved, including our community.”

This was the first murder in Midlothian in the past seven years. Oak Farms Dairy is offering a $10,000 reward for information that leads to the suspect’s arrest and indictment. Since the surveillance video was released on Monday, authorities have gotten several tips. The FBI is also assisting with the investigation.
