Here's some other info from Villgecrazylady on twitter.

Apparently this is a photo - a SELFIE from one of the guys wounded in the attack

So...he's just been shot, blood on him. Ten other people are dead. He TAKES A SELFIE of himself, with a "please help me" caption. Are you kidding me?

Here's this persons LinkedIn. Not suspicious at all. /s
