SANTA FE, Texas: Like some of her classmates, senior Brooke Williams had mixed emotions about returning Tuesday to classes at Santa Fe High School, where a student fatally shot 10 people in the nation’s deadliest school attack since the massacre in Parkland, Fla.

“I’m not excited to go back to school. I’m actually pretty scared to, but I feel like that’s the reason why I need to go back. I don’t want to be scared of this the rest of my life,” Williams said.

Less than two weeks after the shooting, students at the school near Houston were greeted by more than 20 law enforcement vehicles and supporters holding signs saying “Santa Fe Strong” and “United We Stand.”

Students who had classes in the area of the shooting were the first allowed back in, followed by the rest about two hours later. The teens lined up in front of the school’s main entrance, which was the only approved entrance. They were not allowed to carry backpacks or large purses and were required to show an ID before entering.

All students then gathered for a two-hour assembly honoring the victims, and counselors were available for anyone who needed to talk about the May 18 slayings of eight students and two substitute teachers.

Texas Gov. Greg Abbott visited the campus Tuesday, speaking with students, parents, teachers and staff privately and presenting first responders with an award for their actions.

Hailey Hubbard, another senior, was returning for her final week of high school.

“Honestly, I just want to go back so I can see my friends and not spend my last three days of senior year just being secluded in a room,” Hubbard said. She said she did not want the shooting to be her last memory of high school.

Hubbard said some of her friends were more ambivalent about returning to campus and that she had to help calm down a friend who suffered a panic attack at the thought of going back to school.

She hopes returning to campus will also give her mother peace of mind because “she’s terrified of me going to school.” The teen had wanted to ride the school bus she normally takes. But her mother said no because there’s no security on the bus.
