Four students were arrested Monday for allegedly bringing a firearm onto the campus of Corsicana High School.

The weapon was discovered in the backseat of a vehicle after school administrators noticed the students sitting in the car around noon during routine checks. Corsicana ISD police were called, and the students were taken into custody.

The Corsicana ISD officials determined there was no threat to other staff members or students and confirmed the firearm was never taken out of the vehicle. Another student was later questioned and detained.

Once the school day has started, the only way for students to enter or leave the school is through the security check in the front office.

The Dallas Express reached out to Superintendent Diane Frost, who refused to comment on the incident further than the ISD’s press release.

Gun violence has been the number one cause of death in teens since 2020, according to the CDC. Just last year, two students were arrested in Irving ISD at Nimitz High School after gunshots rang out in an on-campus parking lot during a fight, as previously reported by The Dallas Express.

Dallas ISD updated its Comprehensive Safety Plan in 2022. During a press conference, DISD Superintendent Stephanie Elizalde claimed safety and security top the district’s list of priorities.

“At the campus level, our secondary schools have metal detectors for entrances. We also have moved some of our campuses to have clear and mesh backpacks,” said Elizalde. “Ultimately it’s going to take a team approach but we’ve been able to keep our schools very safe and we want to continue to do that.”

Amid concerns about gun violence, community members started a campaign called “Be Smart” to raise awareness for parents to secure, unload, and lock up firearms at home to prevent incidents like the arrests in Corsicana ISD from happening.

Weapons law violations in Dallas rose by 15.2% from 2020 to 2022, according to data from the City of Dallas crime analytics dashboard.
