Open door turned Brooklyn fire into deadly inferno, fire officials say

An open door helped fuel the Brooklyn blaze that raced like a blowtorch through the building, killing a beloved retired schoolteacher and injuring dozens of others, fire officials said Sunday.

The front door to the fourth-floor apartment where the fire began was left open, feeding the vicious flames that killed Mary Feagin and injured 20 firefighters and 11 residents Saturday evening, officials said.
