Investigators say a fitness instructor found dead at a North Texas church had multiple puncture wounds to her head and chest when her body was found.

According to a search warrant affidavit obtained Tuesday by KXAS-TV of Fort Worth and Dallas, the wounds on the body of Terri "Missy" Bevers were "consistent with tools the suspect was carrying throughout the building," as captured on a surveillance video.

The 45-year-old Red Oak woman had driven to the Creekside Church of Christ in Midlothian before dawn April 18 to teach an exercise class. The surveillance video showed a person clad in a police jacket and helmet and roaming the church before Bevers' arrival.

No arrests have been made.
