SLIPPERY ROCK, Pa.—State police say a western Pennsylvania man died in a crash shortly after police tried to pull him over for driving with an expired inspection sticker.

Troopers say the dead man is 20-year-old Adam J. Williams, of Karns City.

Trooper Dan Kesten, the Butler barracks' spokesman, says a trooper noticed the sticker and turned around to chase Williams who passed in the other direction about 1:20 p.m. Wednesday in Brady Township. That's about 40 miles north of Pittsburgh.

Kesten says Williams was thrown from the car when it flipped over about 200 yards away after striking a small hillside. Two girls in the car, 1 and 2 years old, survived, with the 2-year-old suffering only minor injuries.

Online court records show Williams had past citations for driving with a suspended license.
