Natasha Vaughn-Holdridge is reporting for Columbia-Greene Media a lockout of all buildings in the Ichabod Crane school district on November 1, lasted approximately 30 minutes. A lockout means there was thought to a possible threat outside of the school, The threat that gave rise to district officials taking the action in Kinderhook on Monday was later determined to be false. “Our high school principal was notified by a parent of a possible threat to the campus,” Ichabod Crane School Superintendent Suzanne Guntlow said. “Out of an abundance of caution, while we investigated with the Columbia County Sheriff’s Office we put the buildings on lockout.” The lockout keeps students in the buildings and prevents visitors from entering, Guntlow said. “It was first thing this morning; it only lasted about half-an-hour,” she said. The superintendent said she could not reveal any other details about the incident. The tip was shared by a parent with the high school principal and the Columbia County Sheriff’s Office investigated, she said. The county Sheriff’s Office deferred all questions to the school district. Read the full story at HudsonValley360 [dot] com.
