Texas media outlets released a new video showing a number of armed Uvalde police officers waiting in a school hallway, where a lone teenage gunman massacred 19 students and two teachers on May 24.

The officers waited nearly an hour before they moved into the classrooms, despite the fact that the doors apparently were not locked, according to the daily Austin American-Statesman and Channel KVUE-TV, which released the images on Monday night.
