The timeline of how the school shooting in Uvalde, Texas, unfolded, according to a federal report

UVALDE, Texas (AP) — A scathing Justice Department report into law enforcement failures during the Robb Elementary School shooting in Uvalde, Texas, included a minute-by-minute account of missteps by police at the scene. Heavily armed officers did not kill the 18-year-old gunman until about 77 minutes after the first officers arrived at the school. During that time, terrified students in the classrooms called 911 and parents begged officers to go in and save them. Nineteen children and two teachers were killed during the May 24, 2022, massacre in the rural South Texas town.
