KITTERY — The police chief says an autopsy will determine whether a medical problem contributed to the death of a man who was unresponsive when he was pulled from a pond in Kittery.

Chief Edward Strong says 56-year-old Paul Hodgkins was not a strong swimmer and was wearing a life vest when he first went into a pond on Martin Road on Wednesday. He says the man’s wife screamed for help when she saw the life vest floating but did not see her husband.

Hodgkins was pulled from the water by a friend and firefighters and was taken to Portsmouth Hospital, where he was pronounced dead. Strong says investigators were told Hodgkins had underlying medical conditions. A New Hampshire medical examiner was performing an autopsy.
