A four-minute video compiled from footage obtained by the Austin American Statesman and KVUE-TV opens with surveillance footage outside the school as the gunman crashes a truck before firing three shots at two men in the street on May 24. The video also includes audio of a teacher calling 911 saying “I can’t see him” and “the kids are running” before shots are fired toward the school. The teacher shouts ‘get down’ and go to your rooms.’ Footage from inside the school, after the gunman entered at 11.33am, shows him walking down the corridor with a high-powered rifle. He releases his grip on the rifle with his left hand and brushes his hair aside. A student at the other end of the hallway looks at a corner as the gunman walks down the hallway. Seconds later, he unleashes a burst of gunfire in a classroom. He fires his AR-15 rifle for two and a half minutes, according to the video. Law enforcement said more than 100 rounds were fired. Several officers are then seen entering the school hallway about three minutes later at 11:36 a.m., according to the video, where they stand for about a minute. Police entered Robb Elementary School minutes after a gunman walked unimpeded and opened fire in a fourth-grade classroom on May 24. It would be over an hour before officers caught him. (Austin American Statesmen) Then a burst of gunfire. The officers at the far end of the hallway near the classroom where the gunman entered run back to the other end of the hallway. More heavily armed and armored officers arrive and crouch with other officers about 19 minutes after the gunman enters the school. The gunman is still inside the classroom on the other side of the hallway. The officers carry shields, wear body armor and hold high-powered rifles, pointing across the hall. No officers move toward the classroom. About 48 minutes after the massacre began, while officers continue to stand or kneel in the hallway, the gunman is heard firing four more bullets. At one point, around 12:30 p.m., an officer in ballistic gear can be seen dispensing hand sanitizer. A police officer is seen using hand sanitizer about 57 minutes after a gunman walked into Robb Elementary School in Uvalde, Texas, killing 19 children and two teachers on May 24, 2022, as law enforcement waited more than an hour to enter the classroom and Kill him. (Austin American Statesman/KVUE) Seventy-seven minutes later, at approximately 12:50 p.m., police officers burst into the classroom and kill the gunman. More than a dozen officers, most of them heavily armed, line the hallway at that point. The video — compiled from an investigative file that includes security footage from a nearby funeral home, officers’ body camera footage, audio of 911 calls and officers talking to each other in the hallway and surveillance footage from a camera on the school’s hallway ceiling — underscores severe lack of law enforcement response as families and bystanders gathered outside the school pleading with police to save their children. The director of the Texas Department of Public Safety, Steve McCraw, identified school district police Chief Pete Arredondo as the commander of the incident, which Mr. McCraw said publicly he mistakenly identified as a scenario involving a suspect with a barricade, not a active shooter. However, the video shows multiple law enforcement agencies — including officers from the Uvalde Police Department as well as the Texas Rangers and federal agents with the US Border Patrol and the US Marshals Service — stepping up in their response to engage the gunman. Mr. McCraw testified at a recent Texas state Senate hearing that there were enough armed officers on the scene to stop the gunman within three minutes after the shooting began. The US Department of Justice has also launched a parallel investigation into the police response. The release of the footage follows weeks of requests from victims’ families, survivors, Uvalde’s mayor, Gov. Greg Abbott and the media to better understand the failures of that day, with prosecutors citing an active investigation into the massacre in their denial to publicize the video. . Salvador Ramos, 18, fatally shot 19 children between the ages of nine and 11, as well as two fourth-grade teachers. The massacre marks the deadliest school shooting since the 2012 killings at Sandy Hook Elementary School in Newtown, Connecticut, where 20 children between the ages of six and seven were killed, along with six adult staff members.
