Reports of a mother and son still trapped in a Brewster home fully engulfed in flames Wednesday morning turned out to be unfounded. Brewster Fire Department was dispatched to Carmel Avenue on a report of a fire around 8:30am.  Firefighters made several attempts to enter the burning home to search for the trapped residents but were driven back by the intense fire. A short time later it was learned that the two escaped before firefighters arrived.  The gas-fed fire was difficult to extinguish, until NYSEG was able to shut the gas main.  No injuries were reported.  The Red Cross is assisting the displaced families.  Mutual aid was provided by Carmel, Mahopac, Putnam Lake, Patterson and Croton Falls.  South Salem and Bedford Hills covered Brewster and Croton Falls fire districts. North Salem, Carmel ambulance, Putnam County Medic 3 and Ambulanz EMS supervisor stood by at the scene.
