EVANS CITY — Justin Enslen was high on a five-drug cocktail when he headed home from his regular visit to a methadone clinic, according to testimony Tuesday at a hearing.

He was impaired by heroin, morphine, methadone, marijuana and a prescription anti-seizure drug, a trooper said.

But that didn’t stop Enslen. Neither did not having a valid driver’s license.

The 25-year-old suspect, state police said, shortly after 10:30 a.m. Feb. 18 crossed over the center line on Route 68 in front of an elementary school in Connoquenessing Township.

The other driver, Mark Bishop, 52, of Oakland Township, who was on his way to the auto show in Pittsburgh, barely had time to react and was killed in the head-on collision.

Bishop’s sister, who was riding in his pickup truck, is still recovering from her injuries.

Following testimony at Enslen’s 40-minute preliminary hearing, District Judge Wayne Seibel of Evans City ordered Enslen held for trial on vehicular homicide, drugged driving and other charges.

Enslen, of Connoquenessing Township, remains in the Butler County Prison on $10,000 bail.

Police said Enslen was eastbound on Route 68 when his Dodge Ram pickup traveled into the other lane, heading right at Bishop’s Nissan Frontier.

“It happened so fast; (Enslen) just crossed the center line,” testified Bishop’s sister and front-seat passenger, Holly Merkner, 41, of Lyndora. “He looked like he was almost the whole way in the (westbound) lane.”

The last thing she remembered before the collision was her brother trying to swerve out of the way.

But the pickups collided violently. The force of the impact left a gouge in the pavement’s westbound lane, Trooper Kenneth Walker testified.

Leading from the gouge was a scrape mark that cut back across the eastbound lane, where Enslen’s pickup ended up on the south berm.

The physical evidence and witness accounts indicated Enslen caused the deadly crash, Walker told prosecutor Mark Lope, a county assistant district attorney.

Bishop’s truck stopped on the north berm partially on the Connoquenessing Elementary School lawn. There was no school that day because it was the Presidents Day holiday.

Bishop was trapped in his truck. But by the time Connoquenessing volunteer firefighters got him out, it was too late, police said.

He was pronounced dead at the scene of injuries to his body and extremities.

Merkner was taken to Butler Memorial Hospital and treated for a broken rib, sprained wrist, bruises to the forehead and chest, and cuts to the hand.

Also injured, Enslen was “screaming for help” and unable to get out of his truck when the first emergency crews got there, said Trooper Brian Mechling.

Other motorists eventually helped Enslen out of the truck. Before long, police suspected he was impaired.

He was “very moody,” Mechling testified. The trooper said Enslen also appeared “unsteady” on his feet and had a “glassy look on his face.”

Enslen was taken to Allegheny General Hospital in Pittsburgh where he reportedly told an investigator he had been driving home from a methadone clinic in Cranberry Township.

Methadone is a prescription commonly used to treat heroin addiction.

A police drug recognition specialist went to the hospital and examined him.

Walker said police eventually obtained a search warrant for Enslen’s blood that was drawn at the hospital within 90 minutes of the crash.

The blood as well as the defendant’s urine was used for toxicology testing.

The results, Walker said, showed the presence of a heroin metabolite, which is indicative of heroin use.

Also is his system were a methadone metabolite and morphine, as well as THC, the hallucinogen found in marijuana, and clonazepam, an anti-anxiety medication that is also prescribed for sleep disorders.

On cross-examination by Enslen’s attorney, public defender Ryan Helsel, Walker acknowledged that he was unaware if paramedics had given Enslen any narcotics while being treated for injuries at the scene.

The trooper also admitted he did not know if Enslen had prescriptions for any of the drugs identified in his toxicology report.

Enslen is charged with homicide by vehicle while driving under the influence, a felony.

Additionally, he is charged with an accident involving death while not properly licensed, driving under the influence of drugs, driving with a suspended license, driving on the wrong side of the road, careless driving, reckless driving and a seat belt violation.
