TOWNSHIP C — The Maine Warden Service is continuing its investigation into a boating accident on Lower Richardson Lake that seriously injured three of four people from Rumford and Dixfield on Saturday night.

Cpl. John MacDonald identified the four as Christopher and Ann Broughton of Rumford and Gary and Cynthia Giroux.

The Girouxs reside in Dixfield and own a camp on the lake, according to a relative.

MacDonald said in an email that Giroux was driving the boat to the public landing at South Arm at the southern tip of the 6-mile-long lake when the accident occurred.

He said Christopher Broughton told investigators he and his wife, and the Girouxs and two other people had had dinner at a camp and left in a boat between 9 and 9:30 p.m. for the landing. Broughton told authorities that both shorelines were visible when the boat struck a rock near Spirit Island at the southern end of the lake.

It is unclear who the two others in the boat were.

Gary Giroux, who had the most serious injuries, was taken by LifeFlight from Rumford Hospital to Central Maine Medical Center in Lewiston. Cynthia Giroux and Ann Broughton were taken from Rumford Hospital to the Lewiston medical center.

Gary and Cynthia Giroux were not at CMMC on Tuesday, and information on Ann Broughton was not being released, a hospital spokesman said.

Christopher Broughton suffered a laceration over his eye and drove himself to Rumford Hospital.
