Semaj's death remains under investigation by Will County authorities more than four months after she was found wedged under a couch in her home, where at least six adults and as many as 15 children lived. On Friday, the coroner announced she had died of asphyxia and declared the death a homicide. The case has rattled DCFS and lawmakers, who asked how the agency could have failed to protect Semaj despite 11 investigations at her home beginning in April 2015.
