VIDEO: A 95-year-old man and his 71-year-old son were both critically injured in an apartment fire in SoHo. Officials say flames broke out on the fourth floor of the building on Sullivan Street just before 9 p.m. Neighbors say the fire smelled electrical and that they didn't her a smoke detector go off. Video from inside the building shows water damage to some neighboring apartments. "I heard a knocking on my door, a loud bang, then I hear someone yelling in the hallway," resident Korey Benesh recalled. Both men who were injured have been there for decades as longtime residents. Authorities say one other resident and three firefighters were treated for minor injuries. FDNY Deputy Chief Michael Barvels says there was clutter in the apartment and the narrow hallways made the operation difficult.
