The Cook County Medical Examiner told us Jennifer Hudson showed up to identify the bodies of her mother, Darnell, and brother Jason.
It's "standard operating procedure" for a family member to do this, but that doesn't mean it's easy.
UPDATE: William Balfour is now under the custody of the Illinois Department of Corrections. Cops told us the IDOC have taken Balfour for breaking the terms of his parole.
The nature of the violations are unclear, but we're told that although Balfour is in the custody of the IDOC, the "homicide investigation is still active and ongoing."
