EDINBERG TOWNSHIP -- The Highway Patrol is investigating a fatal traffic crash that happened just after 2 p.m. Saturday.
It happened in the eastbound rest area of Interstate 76.
Frank C. Shackelford, 57, of Lake Geneva, Wisconsin, had parked his semi-tractor trailer in a commercial parking space behind another semi-tractor trailer in front of the rest area service building.
He got out of the semi- and walked in front of the cab. At the same time, the semi- rolled forward, pinning him against the trailer of the unoccupied vehicle in front, killing him.
Troopers say a preliminary investigation revealed that the emergency brakes on Shackelford's truck were not engaged.
The investigation is ongoing.
