Law enforcement officials investigating the mass shooting at the First Baptist Church in Sutherland Springs, Texas, said they have not yet been able to get into suspect Devin Kelley's phone. The phone was flown to FBI headquarters in Quantico, Virginia, on Monday for further tests.
Why it matters: Kelley's phone may contain key details about his motives. Authorities said Monday that Kelley was engaged in "a domestic situation" with his in-laws. He reportedly sent angry messages to his mother-in-law before the attack on the church, and his grandmother-in-law was among the people he gunned down.
