ANDOVER – A body found along South Arm Road this past weekend was that of the Rev. G. Michael Chaisson, a Rumford pastor reported missing nearly two weeks ago.

Police on Monday said they still did not know how the 46-year-old Chaisson died, although foul play was not suspected. The pastor’s body was found Saturday afternoon, 10 days after he was reported missing from his Rumford home.

“The manner of death is not suspicious,” said Oxford County sheriff’s Capt. James Miclon. “The cause of death is undetermined.”

Pastor of the North American Old Roman Catholic Church, Chaisson was reported missing Sept. 29 after he failed to return to the Hotel Harris, where he lived.

For more than a week, police from several departments searched for the pastor on the ground and from the air. On Saturday morning, a person driving through Andover found a body lying off to the side of South Arm Road.

Investigators said the body was found on the ground, near a vehicle, and appeared to have been there for a while. An autopsy was conducted Sunday, but the exact time of death had not been pinpointed.

“The body may have been there for a couple days,” Miclon said.

Investigators on Monday were still waiting for results of toxicology testing to help determine the precise cause of death. That typically takes several weeks.

In 1978, Chaisson founded the St. Michael’s Orthodox Old Catholic Church in Providence, R.I. He later moved to Tampa, Fla., before heading to Maine.

Chaisson arrived in Rumford a year-and-a-half ago and established the Catholic sect, chapel and store at the Hotel Harris.

Besides pastoring the small church, Chaisson has also managed the hotel almost since its new owner, John Roza, bought the historic building a year ago. Police said Roza’s books were all in order, and no money or other items were missing from the hotel when Chaisson vanished.

While he remained missing, Rumford and Maine State Police searched many of Chaisson’s favorite spots from Rumford to Rangeley, west to Errol, N.H., and south to the Lewiston area. Officials from the Maine Warden Service also flew over the areas in a search for the missing pastor.

Most of Chaisson’s surviving relatives are in Connecticut, where he grew up. Police contacted his family members shortly after the body was found on Saturday.

A memorial service has been scheduled for Thursday, with the funeral Friday.
