The Second District Appellate court building in Elgin remains closed Tuesday after some suspicious powder was found in a letter at the facility on Monday.

The letter came from an inmate at the Tamms Correctional Center. An FBI spokesperson confirms the substance was found to be non-toxic and non-threatening. But they are still trying to determine exactly what it is. As a precaution, 28 people were decontaminated and examined.
