Choate Mental Health and Developmental Center

No one was charged when staff were caught on a 911 tape threatening violence against a Choate Mental Health and Developmental Center resident who has developmental disabilities. New reporting shows a culture of cover-ups at the facility.

Federal and state officials have urged reforms at the rural facility for people with mental and developmental disabilities. But the state-run center still has more allegations of abuse and neglect than any other in Illinois.

The 24-year-old with developmental disabilities was brutally beaten by his caretakers inside an Illinois-run facility with a long history of patient abuse.
