New York City's fire commissioner says it appears arson caused a weekend blaze that killed five people in Brooklyn.
Commissioner Salvatore Cassano told reporters, "It's very likely that this was an incendiary fire."
Tests for accelerants were incomplete. But Cassano said accidental fires don't usually start at the front door of a building.
Four men and a woman, all Guatemalan immigrants, perished on Saturday. The woman's 2-month-old daughter suffered a fractured skull. The baby's father tossed her from a third-floor window of the burning building.
The fire was the city's deadliest since 2007. That blaze killed 10 people, nine of them children, in the Bronx. - AP
