Nicholas Clark

CORNING, N.Y. -- Twelve illegal firearms were recovered from the home of the man state police said shot and killed a New York State trooper on Monday near Corning, state police announced Friday.

Trooper Nicholas F. Clark, 29, was fatally shot responding to a call that a suicidal man was barricaded inside his home in the town of Erwin, state police said.

The suspect, Steven M. Kiley, 43, was a pre-K to 12th grade principal in the Bradford Central School District.

During the investigation, state police recovered 12 illegal firearms owned by Kiley, including eight assault rifles, one rifle and three handguns. Two silencers and numerous high capacity magazines were also recovered, state police said.

Autopsy results show that Clark died as a result of being struck with buckshot from a 12-gauge shotgun fired by Kiley, police said.

Kiley's autopsy determined that he died as a result of a self-inflicted gunshot wound to the head. Kiley also sustained a gunshot wound from law enforcement to his chest, which would have been fatal had he not taken his own life, police said.

The investigation into Clark's death is continuing.

Funeral services for Clark will be held on at 11 a.m. on Sunday at Alfred University.
