SELINSGROVE — One day after the motorcycle accident death of a 34-year old Port Trevorton man on Route 35 near Selinsgrove Speedway, at about 7:30 p.m. Thursday, state police are asking possible witnesses to the accident to step forward.

Jason Blair, of Port Trevorton, was riding west on Route 35 when his motorcycle was clipped by another vehicle, sending the bike out of control and into a nearby field. Blair flew off the bike and tumbled onto the pavement. No information about the cause of his death is currently available. Police continue to investigate the accident.

“We’re looking for anyone who was traveling on Route 35, on or around the above date and time that might have seen a black Nissan truck and or a Blue Suzuki motorcycle passing other vehicles on the road,” said state trooper Rodney N. Shoeman, Jr., of the Selinsgrove station.

Shoeman also said they are looking for information about a white passenger car that was being passed by the black Nissan truck.

Shoeman would not comment on whether Blair was wearing a helmet at the time of the accident.

He also would not comment on James Mottern, 42, the driver of a 2009 Nissan, allegedly involved in the incident.

Mottern had no comment Friday, when asked about the accident.

Any witnesses or anyone with information is asked to contact police at 570-374-8145.
