Officials have confirmed that the man who fired at a Dallas police building on Saturday morning was killed by a police sniper after an hours-long standoff. Dallas Police Chief David Brown added that police believe the suspect acted alone in the attack.
While officials still haven’t confirmed the suspect’s identity—the man told officers his name was James Boulware—NBC News caught up with Boulware’s mother who said that her son suffered from mental illness and had a history of violence.
The family also confirmed his death in a statement released on Saturday. "We tried to get him mental help numerous times, but the system failed him, because he was declared 'sane.' He was very delusional. It was very obvious."
