A fatal accident occurred about 4:55 p.m. Monday on Route 22 west of Allentown.

It happened on eastbound Route 22 in Upper Macungie Township, just east of the point where that highway splits from Interstate 78 in Lehigh County.

Leibensperger was a passenger in the pickup truck that collided with a tractor trailer.

An autopsy will be performed Tuesday.

The Lehigh County coroner's office and the Pennsylvania State Police are investigating.
