Miami-Dade deputies sweep Columbus High campus after armed-person report; lockdowns lifted with no injuries reported

Rapid response and campus lockdowns

Miami-Dade Sheriff’s Office deputies swarmed Christopher Columbus High School in Southwest Miami-Dade on Wednesday, February 4, 2026, after a report of a potential armed person on campus. The school was placed on lockdown while deputies and a specialized response unit conducted a search of the campus.

The law-enforcement response extended beyond the high school. Nearby St. Brendan Elementary School was also placed on lockdown, and officials with associated St. Brendan church and school facilities reported securing their campuses as the search unfolded in the surrounding area near Southwest 87th Avenue.

What authorities said during the search

Deputies described the situation as an active investigation while they worked to verify the initial report. As the search continued, authorities indicated the call was believed to be a hoax, but the sweep proceeded out of caution.

Law-enforcement vehicles and personnel remained visible around both campuses during the response, with road closures and traffic delays reported in the immediate area. Parents gathered outside the school during the lockdown as deputies continued clearing the grounds and buildings.

Officials later stated there was no shooting and no reported injuries, and that the schools were ultimately cleared.

Outcome: no injuries, lockdown lifted

Authorities reported that no one was hurt and that students and staff were safe. After the search concluded, the lockdowns were lifted and normal operations began transitioning back toward routine dismissal and family reunification procedures.

By late morning, officials’ public messaging emphasized that the threat described in the initial call was not substantiated, while also underscoring that the response required a full sweep of the campuses and nearby grounds.

Why hoax emergency calls draw large-scale responses

Calls alleging an armed person or an active shooter typically trigger a high-priority, multi-unit response because of the potential for mass casualties and the speed at which such incidents can unfold. Standard practice in these scenarios includes immediate lockdowns, perimeter control, and a methodical search of buildings and surrounding areas.

Even when a report is suspected to be false, agencies often continue a comprehensive sweep to confirm there is no threat, account for students and staff, and reduce the risk of misinformation driving unsafe movement on or near campus.
