Uvalde teacher closed propped-open door before shooting, Texas officials say

The gunman used the door to get inside, where he killed 19 students and two teachers.

The finding, released by Texas department of public safety on Tuesday, contradicts an earlier account in which they said a teacher had propped the door open shortly before Salvador Ramos, 18, entered the building. Law enforcement did not intervene in the attack for approximately one hour and 20 minutes.

Travis Considine, chief communications officer for the department, said investigators had determined that the teacher, who has not been identified, propped the door open with a rock but removed it, closing the door, when she ran back inside to get her phone and call 911 after the gunman crashed his truck on campus on the elementary school campus.

The account comes as official accounts of the timeline of the mass shooting shifted in the days following the shooting on 24 May. Investigators are still trying to interview the Uvalde Consolidated Independent school district police chief, Pete Arredondo, who took charge of the law enforcement response. He was sworn into an elected Uvalde city council post on Tuesday.

Several students called 911 pleading for help as gunshots were heard. It was not until 12.50pm that border patrol forced their way in and killed Ramos. Investigators have said they found 142 spent cartridges in the classroom.
