Three people, including two students and a teacher, were injured in a stabbing at Black Hawk Middle School in Warrenton, Missouri, on Thursday, November 12, 2026. Police said a student suspected of carrying out the attack was taken into custody, while authorities worked to secure the school and reunite students with their families.
The incident happened at approximately 7:55 a.m. inside a classroom at Black Hawk Middle School, according to reporting by First Alert 4. The Warren County Ambulance District said emergency crews were called to the school at about 8 a.m. following reports of an assault.
Warrenton police said the suspect, described in local reports as a male student, was taken into custody. First Alert 4 reported that the school district’s superintendent, Gregg Klinginsmith, said the student allegedly stabbed a teacher before attacking two other students and then fled the building. Police detained the student shortly afterwards.
Authorities and local media reported differing levels of injury among the victims. One student suffered what police described as superficial wounds. The second student was airlifted to a St. Louis children’s hospital and was initially reported in serious condition. The teacher was transported to hospital by ambulance.
In a later update, First Alert 4’s report carried by WBKO said the hospitalised student had been upgraded to stable condition and the teacher had been discharged. One of the students was treated and released at the scene, according to the Warren County Ambulance District’s updates reported by ABC 17 News.
The superintendent told First Alert 4 that the student allegedly used a knife with a blade measuring approximately four to five inches. He said he was not aware of recent threats involving the suspect and could not say how the weapon entered the school. Police have not publicly established a motive.
The school went into an emergency response as officers cleared classrooms. By approximately 10:41 a.m., all classrooms had been checked, and school officials and law enforcement were working to reunite students with their parents. The district dismissed students early and cancelled Black Hawk Middle School sports for the day, according to local reporting.
Police said there was no continuing threat to the wider public after the suspect was detained. The investigation remains ongoing, and authorities have not publicly released the suspect’s identity or announced specific charges. Because the suspect is a student and may be a juvenile, officials have provided limited identifying information.
The incident has renewed attention on school safety and the challenges of preventing weapons from entering educational facilities. The superintendent said the district would review its security procedures following the attack and arrange counselling support for students and staff as they return to school.
Families and the school community are now facing the difficult task of returning to normal routines after a frightening incident. Further details about the investigation are expected as Warrenton police and school authorities release additional information.
