CORNVILLE — Speed and poor road conditions are being looked at as contributing factors in an accident that killed a Skowhegan man and injured two others Sunday morning, police said.

Gregory Griffeth, 43, was pronounced dead at the scene of the crash on Shadagee Road, which is also Route 43, said Chief Deputy James Ross of the Somerset County Sheriff’s Office in an email.

Griffeth was driving a 2000 GMC pickup truck towing a utility trailer when his vehicle struck a 2018 Chevy Traverse operated by Sinan Deris, 23, of New York, just before 11 a.m.

The accident remains under investigation and it was unclear Sunday who was at fault, Ross said. He said preliminary indications are that road conditions and excessive speed may have been contributing factors.

Deris suffered possible broken bones in his legs and hand injuries. A passenger in the Traverse, Tunc Sarden, 20, of New York, reported chest pains from the seat belts, Ross said.

The impact of the crash was so severe it caused the truck bed of the pickup to separate from the frame and land in the ditch.

The sheriff’s office and the Cornville Fire Department, Madison Fire Department and Redington-Fairview EMS responded. Maine State Police also assisted the sheriff’s office with reconstruction of the accident.

Ross said blood alcohol tests will also be done on the drivers of the vehicles, as required by law. Upon completion of the investigation, the Somerset County District Attorney’s Office will review the information.

The National Weather Service on Sunday issued a winter weather advisory for northern and central Maine, warning drivers of the possibility of freezing rain and ice accumulation.
