Brookfield Volunteer Fire Department responded to Candlewood Lake last night on a report of a swimmer in distress.  Hearst Connecticut Media reports that emergency medical personnel were called to the area near Echo Bay Marina and Blueberry Island around 5pm.  A bystander pulled the man in his 50s from the water and started CPR.  Paramedics reached the man, who was in cardiac arrest, and transported him to Danbury Hospital.
