PRESS CONFERENCE: Uvalde authorities release new details on Texas school shooting

Texas Department of Public Safety Director Steven McCraw said Friday that nearly 20 officers were in a hallway outside of the classrooms for more than 45 minutes before agents used a master key to open a door and confront the gunman, Salvador Ramos. The on-site commander believed the gunman was barricaded in a classroom at the school during Tuesday's attack and that the children were not at risk.
