Fiore added that the troopers who visited his home where unable to make contact with Kiley and that he was later found dead inside his home.

“After Trooper Clark was hit by gunfire, a deputy sheriff put his own life in danger to pull Trooper Clark to a position of safety,” Gov. Andrew M. Cuomo told reporters.
