Man identified as Louie's shooter had posted on social media about being 'under hardcore demonic attack'

A man who police say shot three people at an Oklahoma City restaurant before being shot and killed himself posted videos on YouTube in which he said he was under demonic attack.

In a video dated April 27, Alexander Tilghman sits alone in a room and speaks directly to a camera, saying his life is in danger and he is under "hardcore demonic attack." Tilghman says he constantly hears cracks and booms throughout the house. He asks for "real people" to get in contact with him.

In a comment on the video, Tilghman pleads for help.
