I think what happened with this guy was there was a shot of the shooter with long blonde hair. And this dude thought it looked like him. He commented on that first picture and somebody on Twitter who seemed like a friend who knew him was like dude. No way.

So then he took a picture in his house in that pose where he's like from behind looking over his left shoulder.

So he posted a picture of himself because he resembled a picture taken of the shooter and it just blew up like insane
