SUTHERLAND SPRINGS, Texas - ABC NEWS:
The suspected shooter who opened fire in a rural Texas church has been identified as 26-year-old Devin Kelley, federal and state law enforcement sources told ABC News.
Kelley is from New Braunfels, Texas.
The investigation into his background is unfolding. The suspect's Facebook profile appeared to show a recent picture of an AR-15-style gun.
The U.S. Air Force confirmed Kelley served from 2010 until his discharge, which the Department of Defense's service verification website reports was in 2014. Ann Stefanek, an Air Force spokeswoman, said records confirmed Kelley served in the logistics readiness department at Holloman Air Force Base in New Mexico.
A source at the federal Bureau of Alcohol, Tobacco, Firearms and Explosives told ABC News the agency is searching for explosives at the suspect's home. The FBI is also searching the man's home.
Texas Department of Public Safety Regional Director Freeman Martin said this afternoon the suspect was wearing all black, including a ballistics vest, at the time of the shooting.
Martin said the suspect was found dead in his truck after running off the road near the county line after fleeing and being fired upon at the church by a resident. Investigators are unsure whether the resident killed the suspect or he killed himself.
Kelley lived at his parents' home with his wife and child, according to neighbor Mark Moravitz.
Moravitz told ABC News he didn't notice anything unusual about Kelly, but said he would sometimes hear gunshots coming from near that house in the evening around 10 or 11 o'clock, which Moravitz said was not unusual, given the area.
At least 26 people died and 20 were injured in the shooting. The exact details of how the shooting unfolded remain unknown.
