Trooper Scott Graham was found by another law enforcement officer who was passing by shortly after 7:30 a.m. Wednesday.
Graham was in a marked patrol car on an exit ramp off the Parkway in Wall Township and was pronounced dead at the scene.
The 35-year-old Graham graduated from the state police academy in 2001 and had been a trooper for 10 years.
He is survived by a wife and three young children.
Graham's death comes less than two weeks after Trooper Marc Castellano was struck and killed nearby on Interstate 195 while assisting in a search for two people believed to have abandoned a vehicle.
