Canisteo fire officials declared a "mass casualty incident" Saturday night after a car slammed into a tree, injuring four, some seriously. State police said the crash happened at 10:10 p.m. on Pierce Road in the town of Canisteo. A female passenger was trapped in the vehicle for some time. Ambulances were brought in from Canisteo, Hornell, Jasper and Greenwood. Multiple advanced life support units responded from Hornell. Life Net helicopter landed near the scene while Mercy Flight landed at the Canisteo Elementary School. The others who were injured were transported to St. James hospital. State police said the vehicle was operated by Kyle James Howland, 17, of Canisteo. Troopers have not released any additional information at this time. The conditions of the injured is unknown.
Note: I've been asked why this was considered a mass casualty incident, with 'just' four patients: A mass casualty incident (often shortened to MCI and sometimes called a multiple-casualty incident or multiple-casualty situation) is any incident in which emergency medical services resources, such as personnel and equipment, are overwhelmed by the number and severity of casualties. For example, an incident where a two-person crew is responding to a motor vehicle collision with three severely injured people could be considered a mass casualty incident. An MCI is declared anytime the injured overwhelm the immediately available EMS response.
