Multiple police officers armed with rifles and at least one ballistic shield were at the site of the Robb elementary school mass shooting in
The timeline the American-Statesman and KVUE reported from the documents included footage from inside the school that showed the 18-year-old gunman casually entering a rear door at 11.33am, walking to a classroom and immediately spraying gunfire before barricading himself. Video showed 11 officers entering the school three minutes later, the outlets reported.
Another officer with a ballistic shield arrived at 12.03pm, and another came with a shield two minutes later. About 30 minutes before officers finally breached the classroom door, Arredondo is heard wondering aloud if the gunman could be shot through a window. At 12.46pm, Arredondo told the tactical team members to breach the door when ready, the outlets reported.
On 2 June, state senator Roland Gutierrez said it was a “system failure” that Arredondo received no word of the pleas for help from people inside the school because he had no two-way radio link with city police. “I want to know specifically who was receiving the 911 calls,” Gutierrez said during a news conference.
