Law enforcement agencies were facing questions and criticism over how much time elapsed before they stormed a Texas primary school classroom and put a stop to the rampage by a gunman who killed 19 children and two teachers.
Investigators were also unable to say with any certainty whether an armed school district security officer outside Robb Elementary in Uvalde had exchanged fire with the attacker, 18-year-old Salvador Ramos, when he first arrived on Tuesday.
