BULVERDE, Texas – New details are emerging after a deadly school shooting Monday at Hill Country College Preparatory High School in Bulverde.

The Comal County Sheriff’s Office said in a statement Tuesday that a 15-year-old student used a .357 revolver he brought from home. Investigators have not identified a motive, though officials say they are reviewing the student’s academic history and other factors.

Authorities executed a search warrant at the boy’s home, seizing several electronic devices for forensic examination as they work to determine what led to the shooting.

Investigators said the student shot a teacher before turning the gun on himself. The teacher remains hospitalized, but her condition has not been released. The identities of both the teacher and the student have not been made public.

No other injuries were reported at the campus, which serves about 250 students in the growing community north of San Antonio.

The school was placed on lockdown shortly after 8:30 a.m., and students were later bused to a nearby middle school for reunification with their families. Some parents waited in long lines, some praying, as they were reunited with their children. The shooter’s family members were also present at the reunification site, officials said.

“We’re trying to collect as much information as we can from witnesses,” said Comal County Sheriff Mark Reynolds.

Reynolds said investigators are working to understand the relationship between the student and the teacher and how the firearm was obtained.

Classes were canceled Tuesday, but counselors are being made available to students and families, Principal Julie Wiley said in a statement.

“Our hearts are with everyone impacted, especially that teacher, their family, and our school community,” Wiley said. “We know this has been a difficult day.”

The school, part of the Comal Independent School District, focuses on preparing students for college through a STEAM-based curriculum, including courses in cybersecurity and engineering.
