Police are responding to reports of a shooting in the New York village of Ellenville.
Three people were reported killed, and a fourth person was also injured, local police said during a press conference.
The incident was being treated as a murder-suicide.
Nearby schools were placed on lock down pending police activity Thursday morning, according to the Ulster County Sheriff's Department.
A police officer with the Ellenville Police Department had confirmed that officials were responding to "a shooting", but declined to comment further on the evolving situation.
The village, located less than 20 miles west of Poughkeepsie, is small, with a population of just over 4,000 people.
