FRANKLIN, Pa. (EYT) —  The case of a McKean County man set to face trial on DUI homicide charges in Venango County next month has taken another strange and tragic turn.

According to a recent story in the Bradford Era, a witness in the case against Paul Morrisroe was seriously injured in an accident Tuesday morning on U.S. Route 6 in Liberty Township.

Kane-based state police said a mid-size pick-up truck driven by Louis Sean Bacha, 53, of Crosby, was traveling west on Route 6 while a tractor-trailer was driving east. As the two passed each other a huge chunk of ice from the roof of the tractor-trailer slid off and flew through the windshield of Bacha’s truck.

The truck veered off the road and came to rest in a field with Bacha suffering severe injuries. He was transported to the Erie County Medical Center in Buffalo, N.Y., for medical treatment, police said.

Bacha had testified at the preliminary hearing in the fatal hit-and-run case against Morrisroe that he had seen Morrisroe driving his truck in the time leading up to the fatal crash. While police forensic evidence allegedly shows Morrisroe was the driver, Bacha is the only witness who came forward to say Morrisroe was driving.

Morrisroe, 40, of Marshburg, is facing charges including homicide by motor vehicle while under the influence of alcohol and marijuana for the June 2, 2015, hit-and-run crash on Route 646 in Cyclone which caused the death of Dakota Heinaman, 20.

Court records said Morrisroe was driving a full-sized pickup truck when he struck a motorcycle driven by Heinaman. Morrisroe allegedly left the scene, driving his truck — without a passenger side front tire — back to his home on Sunny Lane in Marshburg. Police allegedly followed a pavement groove from the scene of the crash to Morrisroe’s garage, where his truck was parked inside.

The trial is scheduled to begin Jan. 17.

It is not known what impact, if any, Bacha’s injury would have on scheduling in the trial.
