A New York State trooper was shot and killed early Monday near Corning, N.Y., after arriving outside the home of a school principal who was said to be suicidal, the authorities said.
The deadly encounter took place sometime after 3:30 a.m., on a secluded, dead-end road not far from the Pennsylvania state line, in Steuben County.
The state trooper who was killed, Nicholas Clark, 29, was one of several officers who went to the home of the 43-year-old principal, after the man’s estranged wife had called 911 saying he was suicidal and might be armed, the authorities said.
