Ramos wrecks his truck near the school after fleeing from the house where he shot his grandmother. He jumps out of the passenger side with a rifle and a bag. He sees two witnesses at a funeral home across the street and fires at them.
He walks toward Robb Elementary School, climbs a fence into the parking lot and starts shooting at the school.

The shooter walks into the west side of the school, apparently through an unlocked door, and fires multiple rounds.

Officers from multiple law enforcement agencies begin to converge on the school. The gunman shoots at the first officers responding to the scene. The officers move back and take cover, then approach the suspect again.
Around this time, the shooter enters a classroom and massacres the students and teachers inside. Officers report hearing at least 25 gunshots from the classroom soon after arriving at the scene.
From 11.40am to about 12.40pm
Officers on the scene call for more help, requesting tactical teams, specialty equipment, body armour, precision snipers and hostage negotiators.
About 12.40pm
US Border Patrol tactical teams arrive, enter the classroom, and kill the suspect.
