FAIRFIELD - A Fairfield 911 dispatcher played the role of local hero earlier today. Authorities say the dispatcher successfully instructed 17-year-old Richard Granger how to perform the Heimlich Maneuver on his choking father. The two were having dinner at home when the incident happened. Once calling 911, the teenager said he had tried the move, but that it failed to work. The dispatcher walked him through the process again, which eventually dislodged the piece of food. Fairfield police say the dispatcher followed protocol.
