At approximately 11:20 a.m.
CST, Devin Patrick Kelley exited from a vehicle at a gas station across the street from the First Baptist Church in Sutherland Springs wearing black tactical gear, a
ballistic vest, and a black face-mask featuring a white skull,
 and wielding an AR-15 pattern
 He immediately fired in the direction of the church.
 He crossed the street and approached the building from the right while firing, and continued to fire while entering the church building with worshipers attending regular Sunday service.
 Inside, he yelled, "Everybody die, motherfuckers," as he proceeded up and down the aisle and shot at people in the pews.
 Police found 15 empty AR-15
magazines capable of holding 30 rounds each.
 According to investigators, the shooting was captured on a camera set up at the back of the church to record regular services for uploading online. The footage shows Kelley methodically shooting the victims, pausing only to reload his rifle.
As Kelley left the church, he was confronted by local resident and former
NRA firearms instructor Stephen Willeford,
 armed with an
AR-15 pattern semi-automatic rifle. Willeford took cover behind a truck and shot Kelley twice.
 Kelley dropped his rifle and fled in his
Ford Explorer as Willeford fired several rounds through the vehicle's window.
 Willeford flagged down a passing pickup truck driven by Johnnie Langendorff, and they 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, the men called 911 and reported their location to the operator; they assumed that the police were on their way to the church. During the chase, Kelley called his father to tell him that he was injured and thought that he would not survive.
 Kelley lost control of his vehicle, and it hit a road sign and flipped before landing in a
bar ditch in
Guadalupe County, near the city of
 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
9 mm and a Ruger
.22-caliber, both of which Kelley had purchased.
