A "domestic situation" might lie behind the massacre that unfolded at a small South Texas church during Sunday services, authorities say. At a news conference Monday, law enforcement officials explained that the gunman — identified by police as 26-year-old Devin Patrick Kelley — had sent threatening text messages to his mother-in-law, who is has attended the First Baptist Church in Sutherland Springs, Texas.
Currently, officials say they do not believe the attack was racially or religiously motivated.
