When state troopers Joseph Perechinsky and William Jenkins were tasked Thursday morning with checking on a call of shots fired at a home in rural northeastern Pennsylvania, they had no idea about the danger they were driving toward.

Police say a 61-year-old man fatally shot a neighbor in rural Pennsylvania and then ambushed responding state troopers, wounding two while firing dozens of rounds from a semiautomatic weapon.

State police asked the public to avoid the area of Route 171 north of Thompson. Two state troopers have been shot.
