A vacant building in Sioux City that was a former meatpacking plant turned into a shopping area, known as K-D Station , is now smoking rubble after a fire Wednesday.
Sioux City fire marshal Chuck Hirsh was on the scene all day and believes the fire started on the fourth floor that once housed a bowling alley.

Hirsch says it will take a couple of days before conditions are right for anyone to enter the building and look for the cause of the fire. The K-D Station was closed down two years ago when an electrical fire broke out and the city declared the building unsafe.
