The Maine Press Hearld reports that 55 year old Neil Begin was shot by an agent of the Maine State Police. Begin died the next day.
According to the Associated Press report in the Press Herald, the medical examiner conducted an autopsy but has not been able to determine a cause of death. Maybe the cause of Begin's death was shock from being shot by the cops? I don't know. Clearly you don't want to leap to conclusions in these matters.
