ALNA, Maine — A Jefferson man died Friday night after losing control of his pickup truck and driving into the Sheepscot River.

Steven Parlin, 27, was traveling east on Dock Road in a 1995 Ford Ranger pickup truck at a high rate of speed when it crossed into the westbound lane, and he lost control of the vehicle, according to a release from the Lincoln County Sheriff’s Office. The truck re-entered the eastbound lane, struck a guardrail and a tree, and fell several feet to the river below.

Members of the Alna Fire Department, Wiscasset Fire and Rescue and Wiscasset Ambulance Service responded with the sheriff’s office. Lincoln County Sheriff’s Deputy Kenneth Hatch and a member of the Alna Fire Department found Parlin deceased in the truck.

The crash is being reconstructed by Sgt. Jason Nein of the sheriff’s office. Sgt. Ronald Rollins and Detective Terry Michaud conducted forensic mapping of the crash site.

Parlin was not wearing a seat belt at the time of the crash, according to the release. A blood sample will be taken by the office of the medical examiner.

Hatch, Maj. Ken Mason and Deputy Kevin Dennison, all of the sheriff’s office, continue to investigate the incident.
