Gunman Devin Kelley's in-laws attended the Texas church he shot up before killing himself on Sunday, a local lawman said.
The in-laws weren't at the Baptist church in Sutherland Springs when Kelley _ decked out in tactical gear and armed with an assault rifle _ killed 26 people, Wilson County Sheriff Joe Tackitt told CNN.
An armed resident first wounded Kelley as he left the church, authorities told the network. The disgraced airman then later turned the gun on himself.
The civilian and another man trailed Kelly for 11 miles until he crashed his car, one of them told ABC affiliate KSAT.
His carnage killed 4 percent of the population in Sutherland Springs, a small town about 35 miles east of San Antonio, Tackitt said.
Kelley's victims ranged from age 5 to 72, and practically everyone inside was wounded.
"I think nearly everyone had some type of injury," Tackitt told reporters Monday morning.
