The gunman accused of the shooting massacre that left 22 people dead at an El Paso, Texas, Walmart on Saturday was in his car — nearly a mile away from the horrific scene — when he surrendered to Texas Rangers, according to an arrest affidavit.
"Agents and police officers at the intersection then observed a male person — the defendant — exit out of the vehicle with his hands raised in the air and stated out loud to the agents, 'I'm the shooter,' " the document states.
