Nineteen children and two teachers were killed when Salvador Ramos targeted Robb Elementary School in Uvalde. The video shows the 18-year-old gunman crashing his truck and entering the building – carrying an AR-15 assault rifle and walking unhindered down a hallway at 11.33am on May 24. Moments later, a child is seen coming around the corner of the hallway and running away. Image: Photo: Austin-American Statesman The police first arrive two and a half minutes later. Two approach the class, but retreat after shots are fired. At 11.52am, more police arrive – armed with guns, wearing body armor and ballistic shields, but seen milling about in the corridor. At 12.30, another police officer is seen stopping to get hand sanitiser.

The footage was captured by the school’s hallway CCTV, and portions have been published by the Austin American-Statesman and KVUE. Delays in the law enforcement response have been the focus of federal, state and local investigations into the massacre and its aftermath.

The result of an investigation by the Texas state legislature is also to be released. Residents in Uvalde have been outraged by what the video shows, and at a council meeting Tuesday night, they called for action and asked police to face consequences.

In a statement, that department’s director, Steve McCraw, said the video provided “alarming evidence” that the law enforcement response was a failure. But he said the families of the dead should have had the chance to see the video first and was “deeply disappointed” by the newspaper’s decision to publish the video. Brett Cross, whose 10-year-old son Uziyah Garcia died in the shooting, said: “We’re tired of seeing things after the media picks up on it. Nobody’s telling us anything. And it’s disrespectful not just to us, but to our children’s memories ».
