GREEN BAY, WI (WTAQ) - Fire investigations are looking into what caused a duplex fire in Green Bay early Wednesday.
The call went out just after midnight to 1361 Smith Street. Fire officials say the building is condemned.
No one is supposed to be living there, but authorities say it appears someone may have been staying in one of the units.
Fire officials say they are treating it as a possible crime scene, but it's too early to say if the fire was arson.
Firefighters had the fire out in about 15 minutes, and the damage was limited to one room.
