Texas law enforcement officials ignored pleas from distraught parents as a gunman was left alone for up to an hour at a Texas elementary school - killing 19 children and two teachers, before a Border Patrol agent charged into the school and killed the suspect.

"Go in there! Go in there!" women shouted at the police soon after the attack began, according to neighbor Juan Carranza, who told the Associated Press about the parents' efforts to get the police to confront the shooter. Carranza said the officers did not go in.

Minutes earlier, Carranza had watched as Salvador Ramos crashed his truck into a ditch outside the school, grabbed his AR-15-style semi-automatic rifle and shot at two people outside a nearby funeral home who ran away uninjured.

Officials say he "encountered" a school district security officer outside the school, though there were conflicting reports from authorities on whether the men exchanged gunfire. After running inside, he fired on two arriving Uvalde police officers who were outside the building, said Texas Department of Public Safety spokesperson Travis Considine. The police officers were injured. -RealClear Politics
