Texas school shooter was hiding in closet when cops broke in: report

The Texas school shooter emerged from a closet and opened fire when police burst into the classroom where he was killing children, according to a report.

A hodgepodge tactical unit led by Border Patrol agents returned fire and killed 18-year-old Salvador Ramos inside Robb Elementary School in Uvalde, an official told the Washington Post.

The Border Patrol agents had arrived to a chaotic scene.

“They told me it was hard to discern who was in charge,” the anonymous person told the Post.

While police were struggling to get their act together, Ramos gunned down 19 children and two teachers inside a classroom.

Law enforcement officers on site didn’t have any breaching material, the Post reported, so they were desperate for a master key provided by a janitor.

Once they got the key, they used a tactical shield provided by a U.S. Marshal for cover, according to the Post. A motley crew of law enforcement officers followed behind a Border Patrol agent carrying the shield.

When Ramos opened fire, three Border Patrol agents and at least one Uvalde County sheriff’s deputy returned fire and killed him.

When officers entered the classroom, they found the surviving children huddled in a corner, the official told the Post.

The first Border Patrol agent arrived on the scene around 12:15 p.m., approximately 45 minutes after Ramos entered the school, the Post reported. The agent spotted bullet holes in the classroom door.

Ramos entered the school at 11:33 a.m., according to Texas state police. He was not dead until 12:50 p.m.
