PENN TWP — A woman was flown by medical helicopter to Allegheny General Hospital in Pittsburgh Thursday morning after her car and a truck crashed on Route 8.

Township officer Jack Ripper said Krystal Koch, 21, of Mars had severe injuries to her legs from the 9:53 a.m. accident.

Ripper said the truck, driven by Steve Lichina, 35, of Gibsonia was pulling out of NES Rentals when Koch's vehicle collided with the rear of the flatbed trailer.

Ripper said Lichina had pulled into the northbound lane, but the bed of the tractor trailer was still angled in the southbound lane.

Koch was driving south when the truck pulled onto the road. Ripper said she tried to swerve right to avoid the truck, but crashed into its rear axle.

Koch was taken to Butler Memorial Hospital before being flown to Pittsburgh. Police said Lichina was not injured.

Township police were assisted by the Middlesex Township Police, the Penn Township Volunteer Fire Department, and the Butler County Sheriff's office.

No charges have been filed as the investigation is ongoing, Ripper said.
