The Sutherland Springs church shooting occurred on November 5, 2017, when Devin Patrick Kelley, age 26, of New Braunfels, Texas, perpetrated a mass shooting at the First Baptist Church in Sutherland Springs, Texas. Kelley killed 26 people, including an unborn child, wounded 22 others, and killed himself. The attack is the deadliest mass shooting in Texas history, and the fifth-deadliest in the United States. It was the deadliest shooting in an American place of worship in modern history, surpassing the Charleston church shooting of 2015 and the Waddell Buddhist temple shooting of 1991.
Kelley was prohibited by law from purchasing or possessing firearms and ammunition due to a domestic violence conviction in a court-martial while in the United States Air Force. The Air Force failed to record the conviction in the Federal Bureau of Investigation (FBI) National Crime Information Center database, which is used by the National Instant Check System to flag prohibited purchases.

Kelley was [...] confronted by and traded fire with Stephen Willeford, a local resident and former NRA firearms instructor who was armed with an AR-15 semi-automatic rifle. Willeford had taken cover behind a truck across the street from the church and shot Kelley twice, once in the leg and once in the upper left torso under his tactical gear. Kelley, who had dropped his rifle during the initial firefight with Willeford, fired back with a handgun before fleeing in his Ford Expedition. Willeford fired one more round as Kelley sped north on FM 539. Willeford then noticed a pickup truck parked at the intersection of 4th St. and FM 539, driven by Johnnie Langendorff.
Willeford approached and entered Langendorff's truck on the passenger side. They then pursued Kelley at high speed for about five to seven minutes. According to Langendorff, they drove at speeds up to 95 miles per hour (155 km/h). While chasing Kelley, Langendorff called 9-1-1 and reported their location to the operator as they assumed that the police were on their way to the church.
During the chase, Kelley called his wife and spoke to her and his parents, informing them "I just shot up the Sutherland Springs church", and telling his father that he was injured and thought that he would not survive. Kelley reportedly repeatedly emphasized how sorry he was. Bleeding from his injuries, Kelley soon lost control of his vehicle, hitting a road sign before crossing a bar ditch at the Hartfield/Sandy Elm Road intersection and finally stopping about 30 feet into the field on the opposite side.
Willeford and Langendorff observed that he was motionless, and police took over the scene when they arrived. Police found Kelley dead in his car with three gunshot wounds, including a self-inflicted head wound. Two handguns were found in the vehicle: a Glock 19 9mm and a Ruger SR22 .22-caliber, both of which Kelley had purchased.
