The maniac who went on a deadly shooting spree in a Texas church in November once choked a woman while forcing her to perform oral sex and also “waterboarded” his ex-wife, according to a newly released police report.

Devin Patrick Kelley, 26, who opened fire in the Sutherland Springs First Baptist Church on Nov. 5, had pinned a woman down on his bed and forced her to give him oral sex in 2013, even choking the poor woman with his penis, according to a copy of the incident report that Comal County sheriffs released in response to a freedom of information request.

Police marked the case “inactive” after three months because the victim was not cooperating with the investigation, records note.

The woman, who was 20 at the time, told police that she was in Kelley’s bedroom at his parents’ house June 17, 2013, when he tried to kiss her and she rebuffed him. So he pushed her down on his bed and climbed on top of the woman, sitting on her chest and pinning her arms beneath his legs, and forced her into performing oral sex.

She told cops that he raped her a few weeks before in the same bedroom as well.

The victim reported the second incident to Kelley’s ex-wife, Tessa Brennaman, who explained to cops that Kelley was also violent with her for the roughly one year they were married starting in 2012.

“We had only been married one month the first time he choked me,” she told sheriffs. “For a whole year he slapped me, choked me, kicked me, waterboarded me and held a gun to my head.”

Kelley beat his wife and their infant son so badly in 2012 that he was kicked out of the Air Force after spending 12 months in the brig for the assault. The incident should have precluded him from buying the guns used in the November massacre, but the Air Force failed to enter his military criminal record into the FBI’s National Crime Information Center database.

Kelley killed 26 people in the church massacre before crashing his car while fleeing authorities and shooting himself in the head.
