Disnard Elementary lockdown lifted after armed man arrested nearby
Disnard Elementary was locked down for about 20 minutes Thursday after a knife threat near campus ended with an armed Springfield man in custody.
Parents tied to Disnard Elementary faced an urgent afternoon disruption Thursday when the school went into lockdown shortly after 2:53 p.m. and stayed that way for roughly 20 minutes while Claremont police searched the area around Hanover Street and North Street.
School officials at the Hanover Street campus ordered the protective response after receiving a report of a person in crisis who was reportedly armed with a knife in the nearby forest. Police said officers moved quickly into the neighborhoods around the elementary school as they checked the woods and nearby streets, treating the call as a potential threat to students and staff during the afternoon dismissal window.
The lockdown was lifted once police determined the danger was no longer present. By then, the incident had ended in the arrest of Trevor Kellyhinterberger, 21, of Springfield, after a chase and standoff in the area. Police said Kellyhinterberger was reportedly wearing a ballistic vest and carrying a knife when he was taken into custody. He faces a resisting-arrest charge.
Disnard Elementary sits at 160 Hanover Street in Claremont and serves grades K-5. U.S. News lists the school at 255 students and 26 full-time teachers, a relatively small campus where any safety response can ripple quickly through pickup routines and nearby traffic. The school’s mission statement says it aims to provide a safe, positive, and personalized learning environment for students in Claremont and Unity, a promise that was tested as officers worked to clear the surrounding area.
The episode also followed a familiar pattern for Claremont schools. In 2024, a separate lockdown at Stevens High School prompted a multi-agency response and a room-to-room search before police determined the firearm involved was fake. The latest incident adds to public pressure on the Claremont School District, which has also been dealing with a multimillion-dollar budget shortfall, according to WMUR reporting.
For families on Hanover Street and in the surrounding neighborhoods, Thursday’s response showed how quickly a report near campus can trigger a schoolwide lockdown, a police search, and a fast decision to restore normal operations once officers say the threat has passed.
