Authorities believe California gunman posted on Facebook around time of shooting, official says

In it, the writer says: “I hope people call me insane … (laughing emojis).. wouldn’t that just be a big ball of irony? Yeah … I’m insane, but the only thing you people do after these shootings is ‘hopes and prayers’.. or ‘keep you in my thoughts’… every time… and wonder why these keep happening. ”

When CNN read the post to a friend of Long’s, who did not want to be publicly identified, the friend said, “That does not sound like Ian to me at all. I don’t know what was going through his head when he wrote this. It must have been terrible.”

Hours after Long was found dead, apparently from a self-inflicted gunshot wound, police searched for clues at the home where he lived with his mother.
