A 16-year-old student allegedly walked a loaded handgun straight through the metal detectors at Kalamazoo Central High School on Oct. 16 and headed to class without being stopped. The weapon wasn’t discovered until later that day, when another student reported it to school administration, setting off a scramble that has now prompted Kalamazoo Public Schools to overhaul how it screens students for weapons.
According to mlive.com, the student entered the school at 2432 Drake Road that Friday carrying the firearm, and the presence of the gun only came to light after a fellow student flagged it to administrators. Kalamazoo Public Schools said surveillance video showed the student passing through the weapon-detection system without triggering an alert, and because the system never went off, officials said no secondary search was conducted at that time, per the same report. The 16-year-old reportedly showed the gun to another student during third period before it was eventually found in his backpack during a search.
But there’s a conflicting account on the record. Per wwmt.com, the student told police a different version of events — that the detector did in fact activate when he walked through, and that he was searched afterward, but the gun wasn’t found. That account directly contradicts the district’s video-based version, and the discrepancy between what the student told investigators and what officials say the footage shows has not been resolved publicly.
How the Gun Was Finally Found
Once police did search the student’s bag, the firearm wasn’t easy to locate. WOOD TV8 reports that officers only found the gun tucked into a concealed rear pocket of the backpack after searching through it twice. The search ultimately uncovered the gun in a concealed rear pocket of the backpack.
Notably, when police later tested the same backpack with the gun inside — but without the student’s Chromebook or other belongings in it — the weapon detection system did go off, according to the police report cited by the outlet. Slade told the district that a review found staff followed procedures, while also maintaining that all procedures were followed during the district’s response.
District Pledges Tighter Screening and More Sensitive Detectors
In response, Kalamazoo Public Schools says it will increase the sensitivity of weapon detectors across the district, according to wwmt.com's follow-up report. The station notes that under the revised procedures, students will have to pass through the weapon detector again until the alarm stops sounding, and staff will use handheld wands both for initial searches and whenever a detector does activate, per the woodtv.com account.
The screening system in question, known as OPENGATE, began rolling out across the district in fall 2025, the same outlet reports. That rollout came after Kalamazoo Public Schools added metal detectors to its middle and high schools that same fall — a shift that followed the district’s purchase of 11 new metal detectors for $171,000 in November 2024, according to an earlier mlive.com report.
Parents Push Back at School Board Meeting
Superintendent Slade and school board members discussed school security on Oct. 22, where Kalamazoo Public Schools officials fielded concerns directly from parents in the room. Parents shared worries about how the metal detectors actually work in practice and asked to see video footage of the student passing through the detector that day, according to the seed reporting from MLive.com.
The case has since been submitted to the prosecutor’s office for review, with officials listing possible charges that include carrying a concealed weapon, carrying a concealed weapon in a school zone, disturbing the peace and possession of a stolen firearm, mlive.com reported. The 16-year-old was lodged at the Kalamazoo County juvenile home following the incident. It is not the first time a weapon has surfaced at the school — a Kalamazoo Central student was arrested in April 2024 after flashing a gun at another student, according to the same outlet’s reporting.
A Rare Setup Among Michigan Schools
Kalamazoo Public Schools says it is the only local district in Kalamazoo County with metal detectors and one of only a handful statewide to use them, according to WKZO. That rarity is borne out statewide: a district presentation cited by wwmt.com found that at least 95% of Michigan secondary schools don’t use weapon detectors at all, making Kalamazoo Central something of an outlier even as it now grapples with a detection failure.
Outside experts note that weapon-detection systems generally allow operators to adjust sensitivity to target different sizes of metallic objects, according to schoolsecurity.org.
Similar Scares Playing Out Elsewhere
Kalamazoo isn’t alone in confronting gaps in school weapons screening this fall. In Texas, Willis ISD ramped up security at Willis High School, including installing metal detectors, after multiple firearm-related incidents over the past year, according to Houston Public Media. That came after a 15-year-old Willis High School student was detained when an anonymous tip led authorities to a loaded firearm in the student’s backpack, the outlet reported. Willis ISD now requires all students to pass through metal detectors and have backpacks searched, with plans to bring in explosives-detection K-9s and roll out a clear-backpack policy in the weeks ahead.
A scoping review on school weapon-carriage prevention, published via pmc.ncbi.nlm.nih.gov, notes that despite the widespread use of measures like metal detectors and law enforcement presence in schools, evidence supporting their overall effectiveness remains mixed. Kalamazoo Public Schools has scheduled a community forum on school safety for Wednesday, Oct. 28, at 5 p.m. in the Kalamazoo Central High School auditorium, where families are expected to press officials further on how the detection system failed and what changes will follow.
