‘There was no thinking about it. Act now. Ask questions later.’ Johnnie Langendorff

SUTHERLAND SPRINGS, TEXAS — Johnnie Langendorff said Monday he was driving to Sutherland Springs to pick up his girlfriend when a barefooted man who’d been exchanging gunfire with the suspect in a deadly Texas church shooting jumped into his pickup truck and exclaimed, “We need to go get him!”

Moments later, the two men were in hot pursuit of a vehicle driven by Devin Patrick Kelley, 26, who police say went on a shooting rampage Sunday at First Baptist Church in Sutherland Springs that left 26 people dead and about 20 others injured.

“He jumped in my truck and said, ‘He just shot up the church, we need to go get him.’ And I said, ‘Let’s go,’ ” Langendorff, a 27-year-old Seguin resident, said Monday.

Langendorrf said he didn’t know the name of the armed resident who had sheltered behind a parked pickup truck while exchanging gunfire with Kelley. But when the armed resident jumped into Langendorff ’s truck, the pair immediately began pursuit of Kelley’s vehicle in a chase that clocked speeds upwards of 90 mph.

Texas Department of Public Safety Regional Director Freeman Martin said at a news conference Monday that the armed resident riding with Langendorff was toting an “AR assault rifle and engaged” the shooter.

Langendorff said Kelley eventually lost control of his vehicle and crashed, prompting the armed resident to cautiously approach the vehicle with his gun drawn. But Kelley didn’t move.

Police arrived about five minutes later, said Langendorff, who did not know if the resident had wounded Kelley during their earlier gunfire exchange. Based on evidence at the scene, investigators believe Kelley died of a self-inflicted gunshot wound.

“There was no thinking about it,” Langendorff said. “There was just doing. That was the key to all this. Act now. Ask questions later.”

Asked if he felt like a hero, Langendorff said: “I don’t really know how I feel. I just hope that the families and people affected by this can sleep easier knowing that this man is not breathing anymore and not able to hurt anyone else. I feel I just did what was right.”

While Langendorff did not identify the man who returned gunfire with Kelly before jumping into his truck, Sutherland Springs resident Julius Kepper said the man was his neighbor, Stephen Willeford, whom he has lived next door to for about seven years. Kepper said he was home when the shooting started Sunday and heard Willeford exchange gunfire, but by the time he got out of his house and looked around police already were arriving.

Kepper described Willeford as a gun and motorcycle enthusiast who regularly takes target practice at property out in the country, and has as many as five Harley-Davidsons.

“Avid gun collector, a good guy,” Kepper said.

Kepper and other neighbors said Willeford’s family has been in the Sutherland Springs area for at least three generations, including a father and grandfather who were in dairy farming. Stephen Willeford is married with two grown children and works as a plumber who installs lines on major projects such as hospitals, Kepper said.

Willeford, 55, told The Dallas Morning News for a story published Monday that he was the first person to confront Kelley.

“I didn’t want this and I want the focus to be on my friends,” he told the newspaper. “I have friends in that church. I was terrified while this was going on.”
