U.S. officials say the man who opened fire in a Texas church had sent threatening text messages to his mother-in-law before the attack.
At least 26 people were killed in the small town of Sutherland Springs on November 5, when a man wearing a tactical-style suit burst into a church and opened fire with an assault rifle.
Texas Department of Public Safety Regional Director Freeman Martin said on November 6 that the attack appeared to stem from a domestic situation.
"This was not racially motivated, it wasn't over religious beliefs," Martin said.
He also said it appeared that the shooter, 26-year-old Devin Patrick Kelley, died from a self-inflicted gunshot wound after first being shot by a bystander.
Wilson County Sheriff Joe Tackitt said that members of Kelley’s family were not present in the church at the time of attack.
Kelley received a bad-conduct discharge from the U.S. Air Force for assaulting his spouse and child and a court-martial sentenced him to 12 months of confinement.
The ages of those killed in the attack ranged from 5 to 72. About 20 other people were wounded.
U.S. President Donald Trump, who is on an Asia trip, described the gunman as a "very deranged individual," and said the shooting was the result of a "mental health problem at the highest level."
