WELLS — A man who was holding at a yard sale at his home was killed this morning after two trucks collided and a 30-foot-trailer flipped off Route 9, also known as North Berwick Road.

Jeff Dickerson of Wells died, police said. Claudette Desjardins, a second person who was pinned beneath the trailer, was transported to a hospital with injuries that were not life-threatening. Their ages were not immediately available.

The accident happened around 8:45 a.m.

David Hoyt Sr., 72, of Wells was driving a Dodge pickup east on Route 9 when he attempted to make a U-turn, said Wells police Officer John Riegel.

Hoyt apparently did not see an oncoming Toyota Tundra, hauling a 30-foot trailer. The driver of the Tundra could not avoid the Dodge, and the two trucks collided, Riegel said. The trailer jackknifed, flipped over and tumbled off Route 9 and onto the property at 1123 N. Berwick Road, where several people were looking at yard sale items.

Dickerson and Desjardins were struck and pinned by the metal trailer, and emergency crews needed to bring in airbags to lift it off the ground. The victims were then rushed by ambulance to Maine Medical Center in Portland, where Dickerson was pronounced dead.

The driver of the Tundra was not injured.

Hoyt, the driver of the Dodge pickup, suffered non-life-threatening injuries and he is being treated at Maine Medical Center.

There is no indication that alcohol was a factor, Riegel said.

An accident reconstruction team from the Maine State Police is leading the investigation to determine what happened, and whether any criminal charges are warranted.
