EAST CAMERON TOWNSHIP - A Coal Township man was in critical condition Monday after jumping from a moving vehicle following an argument with his girlfriend.

Trooper Brian Ronk from state police at Stonington said Christopher Powell, 25, was a passenger in a 2003 Buick Rendezvous driven by Jessica A. Long, 23, also of Coal Township. Ronk said Powell "exited the vehicle for unknown reasons" following the argument.

The incident occurred about 11:09 a.m. along Upper Road about three miles east of Gowen City.

Two small children were seen getting in and out of the SUV while state police interviewed Long and another woman who arrived at the scene and was visibly shaken. The vehicle was parked nearly sideways, the rear end still partially on the eastbound lane.

According to state police, Powell suffered a substantial head injury.

He was transported by an AREA Services ambulance to a field approximately a mile away, where he was taken by a MedEvac helicopter to Geisinger Medical Center, Danville.

As of 9:45 p.m., Powell was listed in critical condition.

The investigation continues, Ronk said.
