Jorge Mas Canosa Middle School in southwest Miami-Dade County went into a temporary lockdown Thursday after police activity broke out near campus, with video showing two men scuffling and a sound resembling a gunshot. Miami-Dade Fire Rescue treated one person at the scene, and Local 10 reported that the person was not transported to an area hospital.
The disturbance occurred in the area of the 15000 block of Southwest 140th Street, according to WPLG Local 10, which obtained video showing the altercation near the school. Miami-Dade County Public Schools said the lockdown stemmed from non-school related police activity in the area, and the station reports the lockdown was later lifted. Police have not yet released official information about what occurred or what they are investigating, per the same report.
Jorge Mas Canosa Middle School sits at 15735 SW 144th Street in Miami's Country Walk neighborhood and has served students since it first opened in August 2007, according to federal school data compiled by the National Center for Education Statistics. The school serves students in grades 6 through 8, per the same data. The school is led by Principal Juan Ramirez, while Assistant Principal Lorena Garrote-Lee Sang was named a district finalist for Miami-Dade County Public Schools' 2026 Assistant Principal of the Year in April, according to information published on the school's administration page.
Why the Lockdown Happened So Fast
Florida law includes emergency-preparedness requirements for public schools, as outlined by Broward County Public Schools. The same statute mandates that schools implement Alyssa's Alert mobile panic button systems, which connect school personnel directly to 911 dispatch centers during active emergencies, according to SaferWatch. That infrastructure, enacted after the 2018 Parkland school shooting, helps explain why administrators at a campus of over 1,000 students moved quickly to secure the building even though the disturbance did not originate on school grounds.
The middle school carries the name of Jorge Mas Canosa, the Cuban exile leader who founded the Cuban American National Foundation and the infrastructure company MasTec before his death in 1997, according to the Los Angeles Times. Mas Canosa remains one of the most influential political figures in South Florida history.
What Florida Law Says About Weapons Near Schools
Possessing a firearm or deadly weapon on school property or within 1,000 feet of a school zone is a third-degree felony in Florida, punishable by up to five years in prison and a $5,000 fine, under Florida Statute § 790.115, according to Leppard Law. The same statute classifies actually discharging a firearm or weapon on school grounds or at a school function as a second-degree felony, which can carry up to 15 years in state prison, according to Pumphrey Law. It remains unknown whether any weapons or shell casings were recovered from the scene, or whether charges will be filed, and police have not identified the individuals involved or their motive.
Other Recent Incidents Near Miami-Dade Schools
Thursday's lockdown is discussed alongside other incidents reported near Miami-Dade County schools this year. A separate September 2 report was also cited, but the available sources do not verify its details. On August 18, a fatal shooting occurred near Laura C. Saunders Elementary School in Homestead, though the school was unaffected and no lockdown was imposed.
For now, the key facts at Jorge Mas Canosa Middle School remain limited to what district officials and the video obtained by Local 10 News have shown: a scuffle, a sound resembling gunfire, one person treated at the scene, and a brief lockdown that has since been lifted. Investigators have not said what led to the confrontation or whether it is connected to any ongoing case in southwest Miami-Dade County.
