**UPDATE** (5:58 PM EST)
Devin Patrick Kelley has been identified as the gunman who killed at least over 20 people at a church in Texas, a U.S. official told The Daily Beast and reported just moments ago.
The Daily Beast reports Kelley, 26, was a resident of New Braunfels, a suburb of San Antonio, according to public records. He was married and Kelley’s mother-in-law listed a P.O. box in Sutherland Springs as a mailing address. A LinkedIn account that looks to belong to Kelley describes him as serving in the U.S. Air Force from the year he graduated high school (2009) until 2013. It also shows he taught at a summer Bible school, per their report here. The cover photo of his alleged Facebook profile eerily displays a gun that appears to be an assault rifle.
