UVALDE, Texas – A report, published by the Advanced Law Enforcement Rapid Response Training (ALERRT) Center in 2022 provided minute-to-minute details about the May 24 Robb Elementary School in Uvalde.
The timeline is similar to the timeline provided by Texas Department of Public Safety Director Steven McCraw several days after the mass shooting but gives additional information and a more in-depth look at what exactly took place as a teenage gunman opened fire during the last week of school.

A combination of internal school surveillance (ISS), video footage from a nearby funeral home (FH), body-worn cameras (BWC), radio logs (RL), officer statements and interviews were used to determine the timeline.
Below is the timeline provided by ALERRT. The abbreviations at the end of each entry indicate how that piece of the timeline was determined.
- 11:27:14, a female teacher (Female 1) exits the exterior door in the west hall propping the door open with a rock to prevent it from closing behind her. (ISS)
- 11:28:25, the suspect becomes involved in a motor vehicle crash in a dry canal near the elementary school. Two people from a nearby business approached the crash scene at 11:29:02. The suspect engaged them both with a rifle. The two people were able to flee back to the business unharmed and called 9-1-1. (FH)
- 11:29:40, Female 1 returns through the west entry deliberately kicking the rock from the door jamb. Female 1 pulls the door shut and continues to look out of the exterior door as she is frantically speaking on her cell phone. Female 1 attempts to enter a door on the south side of the west hallway only to find it locked. Female 1 knocked on the door, and it was eventually answered by another female (Female 2). Female 1 appears to advise Female 2 of the emergency whereupon Female 2 re-enters her room and secures the door. Female 1 moves into a room closest to the exit on the north side of the west hallway. Female 1 re-enters the hallway numerous times yelling down the hall for students to get into their classrooms. (ISS)
- 11:30:14, the suspect, wearing dark clothing and carrying a bag, left the crash scene and climbed a chain-link fence onto the elementary school property. The suspect walked deliberately across the open grounds between the fence and the teachers’ parking lot. The suspect moved towards the school buildings on the westmost side of the campus. Although a defect that might have been caused by a bullet was located on a building south of the affected structure, it could not be substantiated at this time that any rounds were fired at a teacher and children on the playground at the time of the crash. (FH)
- 11:31:36, the suspect is captured on video between the cars shooting, and a Uvalde Patrol unit is captured arriving at the crash site. (FH)

- 11:32:08, the suspect reached the west teachers’ parking lot adjacent to the affected building and fired through windows into the westmost rooms prior to entering the building. (FH and audio file from ISS)
- Prior to the suspect’s entry into the building at 11:33:00, according to statements, a Uvalde Police Officer on scene at the crash site observed the suspect carrying a rifle outside the west hall entry. The officer, armed with a rifle, asked his supervisor for permission to shoot the suspect. However, the supervisor either did not hear or responded too late. The officer turned to get confirmation from his supervisor and when he turned back to address the suspect, he had entered the west hallway unabated. (OS per investigating officer interview).
- 11:33:00, the suspect enters the school from the exterior door in the west hall while holding a rifle. The suspect looked around the hallway and then continued to walk down the west hallway before turning right (down the south hallway).
