The Texas mass shooter had the small town of Sutherland Springs in his cross-hairs before Sunday’s horrific killing inside a church.

Devin Patrick Kelley spent the months before his attack “starting drama” with strangers on Facebook — and he specifically targeted people from “within 20 minutes” of the population-400 town where he committed Sunday’s heinous attack, according to resident Johnathan Castillo.

“It’s like he went looking for it, you know what I mean?” Castillo told the LA Times, referring to Kelley’s Facebook beefs. “You can tell people who are defending their opinions versus someone who’s looking to start something.”

Others described Kelley as a militant atheist who berated the religious online.

Several people un-friended him after social media tirades became too much to handle, according to Castillo.
