Uvalde school shooting report reveals border officers couldn't access school map or keys

As U.S. Customs and Border Protection personnel arrived on the scene of the deadliest school shooting in Texas history, none were able to find a map or keys needed to gain access to critical areas of the building, according to a federal report released Thursday.

While the 18-year-old gunman opened fire while barricaded inside a classroom of Robb Elementary School in Uvalde, Texas, only one of the 188 CBP law enforcement officers who responded had a halligan tool — a device capable of forcibly opening the locked door. 

Amid the chaos, some victims with gunshot wounds were placed on a school bus without first receiving medical attention, the report said. The victims survived, but the report faulted officials for not providing them immediate medical treatment.
