AUSTIN, Texas (AP) — County leaders in Uvalde, Texas, released police body camera video and documents on Tuesday detailing the law enforcement response during one of the deadliest classroom attacks in U.S. history that left 19 students and two teachers dead.

The documents offer a deeper portrait of the teenage gunman and actions of hundreds of law enforcement officers who rushed to the rural South Texas campus.

School officials in Uvalde, Texas, on Monday released text messages, personnel files and student records of the shooter from the 2022 attack at Robb Elementary School, following a yearslong legal battle over public access to the material.
