PITTSBURGH (AP) — A house fire that killed a young child and two women in Pittsburgh was set by a man who smelled of gasoline and bragged "yep, I did it" as he watched the house burn, police said. Pittsburgh police believe Martell Smith, 41, set the fire early Wednesday after getting into a bar fight with a relative of the victims who also lived at the home. A witness told police he overheard Smith muttering "yep, yep, I did it," while fire crews battled the blaze around 2 a.m. Wednesday.
