Trapped residents broke windows for air and stuffed wet towels under doors as smoke rose from a lower-floor apartment where the fire started. Firefighters found victims on every floor, many of them in cardiac and respiratory arrest. More than 5 dozen other people were hurt and 13 people were hospitalized in critical condition. Most of the victims had severe smoke inhalation. There are also reports of shared and common ductwork throughout the building that was constructed under “Federal” codes from years ago.
