Santa Fe High is located in Galveston County about 35 miles outside Houston.
Asked if there was a moment where she felt as though the shooting could not be real, could not be actually happening at her school, Paige shook her head. “No, there wasn’t,” she said with a small hitch in her voice.
“I’ve always kind of felt like eventually it was going to happen here, too,” she said. “So, I don’t know. I wasn’t surprised, I was just scared.”

The gunman opened fired in or near an art classroom, according to multiple media reports.
“I heard really loud booms, and I didn’t know what they were at first,” Paige reportedly said.
The sounds of screams told her what she was really hearing, she said. She and others took shelter backstage at the school, according to station KPRC.
In a statement later Friday, the Sante Fe Independent School District superintendent, Leigh Wall, called the shooting “an unthinkable tragedy.”
“We are grieving the loss of members of our SFISD family,” she said. “We have received an outpouring of support from across the state, and we appreciate your continued prayers for our students, staff and community.”
