The pattern remains unclear

The shooter shot his grandmother, who was hospitalized in critical condition, before heading to school.

The shooter legally owned two AR-15 type long rifles, a Smith & Wesson M&P 15 and a Daniel Defense DDM4 V7. He left one behind and took the other to the school.

He also wore at least a tactical vest, but it’s unclear if he was wearing a body armor, Olivarez told MSNBC. The Bureau of Alcohol, Tobacco, Firearms and Explosives is working with investigators, who are trying to obtain video from inside the school.

The shooter had no adult criminal history and investigators are struggling to find any traces of friends, Olivarez said. He bought the guns shortly after his birthday, officials said.

He had attended high school in the close-knit community about 85 miles west of San Antonio. Abbott said investigators believe the shooter was a high school dropout.

Juan Alvarez, 62, who has been in a relationship with the shooter’s mother for about a year and lives with her, said the suspect left the house about two months ago after he and his mother had a falling out after he disconnected the Wi-Fi. . The two often fought, Alvarez said.

“He was a little weird. I never got along with him. I never socialized with him. He doesn’t talk to anyone,” he said. “When you try to talk to him, he sits still there and walks away.”

An overwhelming number of school shooters — 80% — show warning signs of their attacks, such as discussing them online or in person, said Jillian Peterson, associate professor of criminology and criminal justice at Hamline University in Minnesota.

“The most common is that they tell their classmates,” said Peterson, who has studied hundreds of mass shooters. “We studied school shootings where 50 students knew the attacker was thinking about it.

“We tend to think of these writers as monsters, these outside, bad, horrible people who do these horrible things, and of course what they do is monstrous. But we don’t think of them as insiders — that they’re our classmates, our neighbors, our friends, our children,” Peterson said. “It’s hard to imagine the person sitting across from you doing that.”

The shooter’s grandfather told ABC News he didn’t know his grandson bought guns or that they were at his house.

Because the grandfather, Rolando Reyes, 72, is a criminal, he cannot live in a house with guns, the outlet reported. Had he known, Reyes would have reported his grandson, he told ABC News.
