Devin Patrick Kelley

An angry young loser from Texas drove 35 miles to shoot up a church, killing 26 people and injuring others before getting into a high speed chase with police, getting shot and dying at the scene. At this point not much is known of Kelley other than he served four years in the military before being dishonorably discharged and court marshaled. Oh and he has a wife apparently... who is probably fat. More to come later.
Nobody Could Have Seen This Coming
Oh, wait a minute. Here's a fun thought; if you have someone friended on social media and they unexpectedly start posting pictures of guns just completely out of the blue... probably not a good sign. Especially if they happen to be a loser, socially awkward, a virgin or Muslim.
