Almost a month after somebody murdered a fitness instructor inside a church in Texas, police on Friday signaled progress in the case, saying investigators were able to reconstruct video evidence from the crime scene.

That evidence could help the Tarrant County District Attorney’s office give a more detailed physical description of the killer, KLRD reported. Police did not give any other details.

Investigators previously said surveillance video showed the suspect wearing a helmet, gloves and a jacket labeled "Police." They said the killer was so covered up that they could not determine whether it was a man or a woman.

Terri "Missy" Bevers had arrived at the Creekside Church of Christ in Midlothian early in the morning of April 18 to prepare for her class. Police said evidence of forced entry, including broken glass on the floor, pointed to a possible robbery.

Nearly two weeks ago, police revealed that Bevers and her husband, Brandon, both exchanged flirty messages with other people. The husband's mother last week described the news as "devastating" to the family. The couple had three daughters.

Two companies each pledged $10,000 rewards for information leading to an arrest in the woman's case, Fox 4 reported.
