Police said speed was likely a contributing factor in a fatal single-car accident in Northport June 29.

At about 10:20 p.m. police said Scott N. Riley, 35, of Stockton Springs was traveling “at a high rate of speed” on Route 52 when the car he was driving began to skid along the road. Police said they believe the car then spun around 180 degrees, entered a ditch on the north side of the road and rolled over “at least two times” before finally landing on its wheels.

A couple who live nearby heard the accident, investigated the noise and immediately notified police after they spotted Riley’s car in the ditch. Deputy Dan Thompson of the Waldo County Sheriff’s Office arrived at the scene shortly after and found Riley, who had not been wearing a seatbelt at the time of the accident, unconscious and “partially on the passenger’s side of the vehicle compartment.”

Police said Belfast and Northport rescue crews who arrived at the scene attempted CPR on Riley, but were unable to save him. According to police, Riley died as a result of head trauma he suffered from the crash.

The 2008 Ford four-door Riley was driving was totaled in the accident.

Keating said the crash, which is currently being reconstructed by Deputy Benjamin Seekins, is still under investigation by Thompson.
