A woman who was found murdered last month in a Texas church received a "creepy and strange" message days before her death, according to a search warrant. 

Terri "Missy" Bevers, 45, was found dead early on the morning of April 18 at the Creekside Church of Christ in Midlothian. She had gone there to prepare to lead an exercise class and her body was found by several of her students. Authorities said Bevers had suffered multiple puncture wounds to her head and chest. 

Surveillance video showed an unidentified person wandering through the church in SWAT gear in the moments before the murder.

According to an affidavit, Bevers had shown a friend a message that had been sent to her on LinkedIn, a business networking social media site. The document said that neither Bevers nor her friend knew the man who sent the message and both agreed that it was "creepy and strange."

Police said Bevers' friend did not remember the name on the account that sent the message. 

The affidavit also reveals that Bevers and her husband Brandon had been struggling with marital and financial problems. Police said Bevers had been receiving "flirtatious and familiar" LinkedIn messages from another man since January. 

Police told FOX 4 the man messaging Missy has been cooperating with investigators and is not considered a suspect or a person of interest.

The affidavit seeks access to Terri and Brandon Bevers' phone records, as well as those of seven other people. Police reportedly believe Bevers had been in contact with her assailant. The documents state it is possible that Bevers' killer had a cell phone on him or her, and may have used it to document the murder. 

"I loved my wife," Brandon Bevers said in a statement Thursday. "My children will always know that as well. The children are my greatest concern right now given the information they will eventually receive in one form or another. This is concerning to all of us."
