Dear GCISD parents,
On Tuesday, CHHS was placed in lockdown late in the afternoon as a precautionary measure after a note referencing a possible school safety threat was discovered on campus. The district also placed nearby schools Heritage Middle and Heritage Elementary on a temporary lockdown as a precaution.
District leaders have worked closely with the Colleyville and Grapevine police departments to ensure that the building, lots and field areas are safe. Police and GCISD personnel have conducted a full sweep of the CHHS building and perimeter. Since the note referenced the possibility of weapons, the district also has called in a third-party service to sweep the building using a dog trained to detect gunpowder-based weapons. Additionally, we will have an increased presence of police and administration on these campuses throughout the week.
Police and school leaders continue to investigate the source of this threat. I want to assure you that we take the responsibility of student safety very seriously and our staff works closely with the Colleyville, Euless and Grapevine police departments in preparing for situations such as this. GCISD has an active emergency management team that partners with local law enforcement agencies to review and revise the district’s emergency management procedures.
As part of our procedures, we conduct safety audits of all schools and each campus practices safety drills, including those for a building lockdown. I want to commend the students and staff for their efficiency in putting what they have learned through these drills into practice. I also thank the police for their swift and thorough response.
We are dedicated to providing a safe and secure environment for the students, faculty, staff and visitors on our campuses. Our awareness remains heightened about the safety of our schools and we ask your continued help by reporting any concerns you notice. Working together, we can ensure our schools and facilities continue to be safe places for our students and staff. Thank you for your vigilance and your cooperation.
Sincerely,

Robin Ryan, Ed.D.
GCISD Superintendent of Schools
