The Texas gunman who killed at least 26 churchgoers after opening fire with an assault rifle had a criminal background.
Devin Patrick Kelley, 26, had been dishonorably discharged from the U.S. Air Force in 2014 after he assaulted his wife and child, CBS News reported. He was previously court-martialed for two counts of assault in 2012, and served a year in confinement along with the bad conduct discharge, according to Air Force spokesperson Ann Stefanek.
Kelley showed up at First Baptist Church of Sutherland Springs on Nov. 5 wearing all black, tactical gear, and a ballistics belt. He was armed with a rifle and began firing at churchgoers.
"My dad saw the gunman run into the church building and then he heard shots and saw people running," David Flores told CNN. "People covered in blood and screaming. It was pandemonium everywhere."
As Kelley was leaving the church, he was shot at by a local resident who was also carrying a rifle, said Freeman Martin of the Texas Department of Public Safety. Kelley then dropped his weapon and fled from the church.
Another witness, Johnnie Langendorff, told CNN affiliate KSAT he saw Kelley and the armed resident shooting at each other. He said the resident "briefed me quickly on what had just happened and said we had to get him, and so that's what I did."
Langendorff and the resident chased Kelley and called police. Langendorff said Kelley "eventually lost control on his own and went off into the ditch."
"The gentleman that was with me got out and rested his rifle on my hood and kept it aimed at [Kelley], telling him to get out," Langendorff recalled. "There was no movement, there was none of that. I just know his brake lights were going on and off, so he might've been unconscious from the crash or something like that. I'm not sure."
Police eventually found Kelley dead in his vehicle with a gunshot wound.
"At this time, we don't know if it was a self-inflicted gunshot wound or if he was shot by the local resident," Martin said.
Authorities said they found multiple weapons in Kelley's car. The case is currently being investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives and the FBI.
According to his Facebook page, which has since been deleted by the FBI, Kelley became a Bible studies teacher after he was discharged from the Air Force. He had recently shared a picture of an AR-15 on his Facebook page with the caption, "She's a bad b***h," according to the Daily Mail.
President Donald Trump took to Twitter to respond to the mass shooting.
"May God be w/ the people of Sutherland Springs, Texas. The FBI & law enforcement are on the scene. I am monitoring the situation from Japan," the president tweeted.
"...Americans do what we do best: we pull together. We join hands," Trump added. "We lock arms and through the tears and the sadness, we stand strong…"
During a news conference on Nov. 6, Trump added that he believes the shooting was a result of a "mental health problem," not U.S. gun laws.
