Police said Terri Bevers, a 45-year-old mother of three, arrived at the Creekside Church of Christ in Midlothian at 5 a.m. to teach an exercise class – about an hour after the suspect was seen on camera roaming the church's halls.
In a news release posted to Facebook on Tuesday, Midlothian police said that contrary to earlier statements referring to the suspect as a man, the gender of the suspect has not been determined.
"To clarify, at this point there are insufficient facts to justify referring to the suspect as either a male or female, as we acknowledge either is possible," police said in the release.
"The department's desire is for the public to analyze the video to see if the walk and stature of the suspect is recognizable."
Police added that they are not speculating on the suspect's motive.

Midlothian Police Chief Carl Smith told reporters at a Monday press conference that the suspect's outfit was "designed to look like a police officer" – the suspect was seen in the footage wearing a helmet, shin guards, gloves, a tactical vest and a shirt with the word "POLICE" across the back.
During a Tuesday press conference, Bevers's husband, Brandon, described his wife as a "Godly woman" who "will be missed by many people."
"We are very proud of all the passion and effort she has put into so many people's lives."
