Police say the body was recovered near Camp Cobbossee, which had been rented by two Massachusetts high schools for a weeklong football camp.
The victim, Aaron Ortiz, was entering his first year at Oliver Ames High School in North Easton, MA.
Officials say the boy, an inexperienced swimmer, went into the water without a life vest on. He went out about 50 yards into the lake when he went underwater.
The body was recovered after a search by divers from the Maine Warden Service and Kennebec County Sheriff’s Department. The football camp has been canceled and the rest of the football players are leaving the camp today.
