A Kammerer Middle School student was arrested Thursday after a weapons detection system flagged a gun hidden in a backpack before the school day even began. The arrest happened without incident, and the middle school at 7315 Wesboro Road in Louisville continued operating on a normal schedule for the rest of the day.
According to WDRB, the gun was found inside the student's backpack after the campus weapons scanner alerted staff. A Risk Assessment Coordinator escorted the student to a secure, private location and took the backpack, gun still inside, before Jefferson County Public Schools police arrived, arrested the student, and took the firearm into custody. Principal Shannon Corrigan said all systems worked exactly as intended, crediting the Risk Assessment Coordinator and the JCPS Police Department for what she called a swift and dedicated response.
How the Scanner Caught the Weapon
The detection system at Kammerer is part of a district-wide rollout of Evolv AI-powered weapon detection technology, which Jefferson County Public Schools finished installing across all middle schools in early 2025 at a cost of $4.2 million, following an earlier deployment in high schools, according to WHAS11. A JCPS informational letter sent to families in October 2024 explains that the Evolv Express system scans students in real time using low-frequency radio waves, flagging concealed weapons without requiring backpacks to be emptied at the door, though independent testing has noted the system can produce false alarms from items like metal binders.
District data reported by the same station showed guns found during school hours across JCPS dropped from 28 in the 2022–2023 school year to just four in 2024–2025, a decline district officials attribute directly to the weapon detectors. Kammerer, which serves roughly 780 students in grades 6 through 8 with a 15-to-1 student-to-teacher ratio, has seen its own security scares before: in May 2022, the school was placed on lockdown following student fights and an unconfirmed report of a firearm, though a joint search by LMPD and JCPS security turned up no gun on campus at that time.
What Happens Next for the Student
The student arrested Thursday will face discipline according to JCPS policy, per WDRB's reporting. Kentucky law treats gun possession on school grounds seriously: under Kentucky Revised Statute § 527.070, possessing a firearm or deadly weapon on public or private school property is a Class D felony carrying up to five years in prison and a fine of up to $10,000. Separately, under Kentucky Revised Statutes § 527.100 and § 527.110, possession of a handgun by a minor under 18 is charged as a Class A misdemeanor for a first offense, while unlawfully providing a handgun to a minor is itself a Class D felony — a distinction that could matter if investigators look into how the student obtained the weapon.
State law also required the swift protocol Kammerer staff followed. Kentucky Revised Statute § 158.155 mandates that any school employee who knows or has reasonable cause to believe a firearm is present on school property must immediately notify local law enforcement and school administration. The JCPS Police Department, which employed 50 sworn officers and command staff alongside non-commissioned security personnel as of July 2024, oversees safety for more than 96,000 students across the district.
A Budget-Strapped District Leans on Technology
Thursday's incident underscores how central the Evolv scanners have become to school safety just as JCPS grapples with serious financial strain. As Hoodline reported earlier this month, the district entered the 2026–2027 school year after cutting roughly $115 million in tentative budget expenses and eliminating hundreds of positions while still managing an $82 million working deficit. Against that backdrop, Thursday's arrest offered a real-world test of whether the district's multi-million-dollar investment in detection technology can keep working as intended even as other resources tighten.
