Three Injured in Stabbing at Black Hawk Middle School in Warrenton, Missouri

Three people — two students and a teacher — were injured on Thursday morning, November 12, when a student stabbed them inside a classroom at Black Hawk Middle School in Warrenton, Missouri. One student was airlifted to a children’s hospital in St. Louis and was later reported in stable condition, while the teacher was taken by ambulance and a second student suffered only superficial wounds. Police arrested a male student nearby, and officials said there was no ongoing threat to the public.

The attack happened during the first hour of classes at the school, which serves nearly 700 students in sixth, seventh and eighth grades. The Warren County R-III School District put its schools on lockdown, and hundreds of parents waited for hours outside the building to be reunited with their children.

What happened inside the school

Warren County R-III Superintendent Gregg Klinginsmith said the stabbing began during first period. The student, whom the superintendent identified as male, arrived late to class and stabbed a teacher almost immediately after he arrived, then attacked two students.

Around 7:45 a.m., a Missouri Highway Patrol dispatcher said over the radio that a teacher may have been stabbed at the school and that Warren County and Warrenton officers were on their way. A short time later, a broadcast description went out for a young male with shaggy blonde hair, wearing a black T-shirt, last seen heading west from the school. Seconds later, an officer responded: “Got him detained.”

At 8:06 a.m., Klinginsmith emailed parents that “a student stabbed several students” and that district schools were on lockdown. The Warrenton Police Department posted its first public notice of the incident at 8:30 a.m.

The three victims

The Warren County Ambulance District said it responded to the school around 8:00 a.m. and treated three patients. One student was flown by medical helicopter to a trauma center, and the teacher was transported by ground ambulance. Both were in serious condition at the time of transport. A third person was treated and released at the scene.

The student who was airlifted was taken to Cardinal Glennon Children’s Hospital in St. Louis. By early Thursday afternoon, police confirmed to First Alert 4 that the student was in stable condition.

The second student, the school district superintendent’s son, was stabbed in the hand and suffered superficial wounds, police said. He was released to his parents.

Police have released no information about the suspect beyond identifying him as a male student at the school, and they have not said what charges he may face. According to First Alert 4, police said there were no threats leading up to the incident. The motive remains unknown.

School lockdown and reunification

Students inside the school spent hours in lockdown. Eighth grader Gretchen Looman told the St. Louis Post-Dispatch that her classroom was locked down for about two hours, and she was able to text her father during that time.

All classrooms had been cleared by 10:41 a.m., and the district dismissed all of its schools early, at 12:41 p.m. Black Hawk Middle School sports were canceled for the day. Parents were directed to meet their children at Binkley Park, across the street from the school, where hundreds gathered and embraced their children as they were released.

Klinginsmith called the attack “an isolated incident by one student, who is in custody,” and said the district would go through “the due process and discipline of that.” He said he expects Black Hawk to open on Friday with additional counseling available for students.

Background: a small community shaken

Warrenton is a town of about 9,600 people, roughly 55 miles west of St. Louis. Black Hawk Middle School sits off Highway 47 and is one of the Warren County R-III district’s schools.

Parents at the scene described the shock of an attack in a place they considered safe. Corey David Parton, whose eighth-grade son messaged his mother from a tablet to say he was okay, said the incident raised questions about school security.

“It’s kind of frightening to send your loved ones to a place they can’t come back from,” Parton said.

Why this matters

School stabbings remain far less common than shootings, but any attack inside a classroom raises the same urgent questions about how schools detect warning signs, respond in the first minutes, and protect students and staff. Thursday’s incident also tested the district’s emergency communication: parents received an email within minutes of the attack, and the school moved hundreds of students through a controlled reunification in a matter of hours. It came on the same day as a deadly shooting at a Washington gym, in which one person was killed and four wounded — a reminder that violent incidents in public places can unfold with little warning.

The speed of the police response — officers detained the suspect within minutes of the first radio call — limited the attack to a single classroom. But for families in Warrenton, the incident is likely to reopen a local debate about school safety measures, including whether the district should install metal detectors. One parent at the scene said the attack “is going to open up discussions about metal detectors,” noting the school does not currently have them. Just this week, hoax bomb threats forced evacuations at thousands of schools across Europe, a reminder that school safety is under strain well beyond one Missouri town.

Latest developments

The hospitalized student is in stable condition at Cardinal Glennon Children’s Hospital, according to a police update reported by First Alert 4 on Thursday afternoon. The Warrenton Police Department is leading the investigation, and police said there is no threat to the public. Black Hawk Middle School is expected to reopen on Friday with extra counselors on hand, and district officials have not yet announced any charges against the student in custody.
