Cause of Central City fire may never be determined

The state fire marshal says we might never know the cause of a Thanksgiving Day fire in Central City.

Authorities say the fire started about 8 a.m. Thursday at the Iowa Gold Distributing recycling business.

Smoke and flames from the fire could be seen for 10 miles. The fire destroyed two of the business's buildings and caused an air quality concern for part of the day.

The state fire marshal's office says the fire started in a west building. But because of the destruction, investigators say they are unable to determine the cause.
