NEWPORT (AP) – A 73-year-old Connecticut man was injured Thursday in a gas explosion at his summer lakeside home.

Donald Lamson of Westbrook, Conn., was taken to a Pittsfield hospital and then airlifted to Eastern Maine Medical Center in Bangor after the explosion, which happened at about 7:30 a.m., officials said.

Neighbors found Lamson inside the doorway of his camp after hearing the blast, spokesman Stephen McCausland of the Maine Public Safety Department said. Lamson had been staying at the camp along the shore of Sebasticook Lake for most of the summer.

Investigators from the state fire marshal’s were trying to determine the cause of what appeared to be a liquid propane explosion, McCausland said.

The camp, which was destroyed, was heated by gas.
