😬 someone noticed posts on Instagram, contacted the Anne Arundel County police, who in-turn passed it off to Fairfax County Police, who then notified Prince William County Police about the potential threat.

Police said he was carrying a loaded, semi-automatic pistol with another magazine, plus a knife.

Hours later, police searched his home and made a disturbing discovery.

“[Officers] found a kill manifesto, the likes of which I’ve never read,” Davis said. “But he also articulated that he didn’t know anyone at that church. He articulated that his would-be victims, and he put it out there … He knew he was going to take many lives yesterday and he also said, ‘I don’t know any of them.’”
