Pennsylvania State Police say a deer struck by a vehicle crashed through the windshield of another vehicle headed in the opposite direction, killing a Butler woman riding in the second car.
Troopers from the Butler barracks say the dead woman is Carol Mitch but they didn't immediately release her age.
State police said the crash happened about 6:20 p.m. Sunday when a car traveling south on Route 8 in Brady hit the deer. The driver and passenger in that car weren't hurt.
But the deer was knocked into the path of a northbound car driven by Raymond Mitch, of Butler, state police said. His front-seat passenger was killed and a female riding in the back also suffered minor injuries, state police said.
State police were still investigating Monday.
