Antigo - We have more information for you about the fire that devastated an Antigo apartment building Sunday.

Antigo fire crews and state fire marshals wrapped up their investigation and the cause of the fire is undetermined. But Fire Chief Jon Petroskey says they can't rule out careless use of smoking materials.

The fire started on an upstairs balcony and the wind spread it to the attic area. Upper apartments were destroyed by water and falling burning material, while the downstairs has some smoke and water damage. Chief Petroskey says an insurance adjuster will inspect the building and determine whether it's a total loss.
