BEAR CREEK TWP. — A motorist committed suicide during a traffic stop on the Pennsylvania Turnpike on Friday night, according to state police.

The incident happened shortly after 10:30 p.m. in the north travel lanes of the turnpike's Northeast Extension, near mile marker 98.5 in Bear Creek Township, police said in a news release. A trooper stopped a 2001 Chevrolet Impala "that was being operated in an erratic manner," police said.

The trooper asked the male driver to exit the vehicle to perform field sobriety tests, but the man instead pulled out a revolver and shot himself in the head, killing him instantly, police said.

Officers found illegal drugs when they searched the Impala, according to police.

The dead man was a 22-year-old from Philadelphia, police said. His name is being withheld pending notification of his next of kin.
