Seventy-seven minutes of video footage assembled from the massacre at Robb Elementary School in Uvalde, Texas, reveals the real-time assault after a gunman violently crashed a truck across the street then entered the school unimpeded, killing 19 children and two teachers, while law enforcement spent a painstaking hour waiting in the hallway as shots can be heard inside a classrrom.
A four-minute video assembled from footage obtained by the Austin American Statesman and KVUE-TV opens with surveillance footage from outside the school, as the gunman crashes a truck before firing three shots at two men on the street on 24 May.
