Investigators say they know what caused the Jay Street fire that left four dead and dozens homeless.
The origin of the March 6 fire was traced back to a single apartment in the 100-102 building: city officials told local media late Friday afternoon that a chair in Apartment C1 caught fire. The room had various smoking materials inside, including ashtrays and incense.
The tenant opened a window and dragged the chair toward the hallway, which apparently fanned the flames. Arson charges have been ruled out, but there may be other charges.
A demolition team is taking down the fire-ravaged buildings.
