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.

The gunman, who was killed by police, fatally shot his neighbor in her driveway before firing at responding officers, who survived with serious injuries.

Two Pennsylvania state troopers were shot and wounded Thursday, Aug. 7, while on duty, police said. The shooting happened around 11:15 a.m. after Trooper Joseph Perechinsky and Trooper William Jenkins responded to a call near State Route 171 in Thompson Township, Susquehanna County, Pennsylvania State Police said in a press release.
