Newly released records surrounding the May 2022 massacre, including hundreds of pages of files and hours of body camera video, show in greater detail the heartbreak and failures of one the worst school shootings in U.S. history. Nineteen children and two teachers were killed.

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.
