Dansville High School went into lockdown for about 90 minutes Thursday after an unnamed distraught high school student entered his classroom with alleged intentions to harm himself with a knife.
The classroom was subsequently evacuated and all adjacent school buildings went into a modified lock down, Superintendent Paul Alioto said. The middle school, located off the main campus, was on high alert.
High School Vice Principal Thomas Roote entered the room and spoke with the student, listening to him more than anything else, Alioto said.
Roote stayed with the student until law enforcement officers arrived. A trained hostage negotiator spoke more with the student and convinced him to disarm.
The student was then taken into custody without having caused any injury to himself.
School Resource Officer Dan Rittenhouse, a Livingston County Sheriff’s deputy, was present and took control of the scene.
Livingston County Sheriff John York, sheriff deputies, Dansville police, state police and Department of Environmental Conservation police responded to the scene and ensured the school’s security.
Alioto commended the school staff, administrators and law enforcement officials who acted dutifully in response to the situation.
All after-school activities were cancelled, and school resumed as usual the following day.
Alioto sent out a recorded telephone broadcast to parents and staff once the situation had ended, explaining what had occurred.
