APPLETON, Wis. — An apartment building is destroyed in a fire in Appleton.
It broke out around 2 a.m. Wednesday near the 200 block of North Appleton Street.
The building's owner says 7 people lived in these apartments and were home at the time of the fire.
Fire crews say 8 tenants were evacuated safely.
Officials say they believe this is a natural gas fire but they still can't confirm a cause.
The heaviest smoke and fire was found in the kitchen area of the downstairs restaurant.
The building is a total loss.
