"NOV. 5, 2017 A gunman identified as Devin Patrick Kelley, 26, opened fire at a Sunday service in a rural Texas church, killing at least 26 people. The authorities said Mr. Kelley used a Ruger AR-15 variant, a knockoff of the standard service rifle carried by the American military. 2012 Mr. Kelley, who was in the Air Force, was convicted of assaulting his wife and breaking his infant stepson’s skull. An airman first class, he was sentenced to 12 months’ confinement and a reduction to the lowest possible rank, E-1. 2014 Mr. Kelley received a “bad conduct” discharge from the Air Force. 2016 - 2017 Mr. Kelley purchased two firearms — one in 2016 and one in 2017 — from two Academy Sports & Outdoors stores in San Antonio. He passed a federal background check in both cases, according to a statement released by the store. NOV. 5, 2017 Twenty-six people were killed and at least 20 more were wounded at the church shooting in Sutherland Springs. Mr. Kelley was later found dead in his vehicle. The police recovered two additional handguns from the car. NOV. 6, 2017 The Air Force admitted that it had failed to enter Mr. Kelley’s domestic violence conviction into federal databases, which could have blocked him from buying the rifle he used in the massacre."
