Salvador Raimondo Ramos, the young man identified as the Uvalde elementary school shooter, barricaded himself with his victims in a center assembly hall before executing them, according to the spokesman for the Texas Department of Public Safety, Lt. Chris Olivarez.

Ramos barricaded himself around his victims and shot them, killing two teachers and 19 children, Olivarez said, for whom this way of acting shows “simply the total evil of the shooter,” reports CNN.

Olivarez has said that the agents in charge of arresting Ramos toured the school almost completely before they could find him, force the lock on the assembly hall and shoot him down.

The 18-year-old was wearing a bulletproof vest “used by tactical teams, such as SWAT”, and was carrying an assault rifle.

For the moment, Olivarez has not dared to give a figure of how many more children could be injured. «It was a small assembly hall, there could have been between 25 and 30 students there (…) I don’t have the exact number (…). It was the typical one where there are large groups of children (…) all together, with nowhere to go », he said.

“There are many unanswered questions,” said Olivarez, who has reported that the Texas authorities are already working with the FBI to determine if the school was a specific target of Ramos. “We are looking if there was any indicator, any red flag, looking at social networks,” she explained.

“What we know about the shooter is that he resided here in Uvalde, attended one of the local high schools, lived with his grandparents, was unemployed, with no friends, no girlfriend that we can identify at this point, no criminal record, no affiliation with gangs either,” he said.

Olivarez has said that Ramos’s first victim, his own grandmother whom he shot before breaking into the school, is alive and that they are trying to locate his grandfather and other close relatives.
