ABC will air a special Casey Anthony-inspired episode of Body of Proof on Jan. 17 that features Marcia Gay Harden as its “Nancy Grace.”

As first reported by EW, the episode is about a young woman named Hillary Stone who is acquitted for murdering her son. The action will begin on the day Hillary is released from prison. Harden has been cast as Sheila Temple, a Nancy Grace-like “journalist” who has doggedly reported the story of Hillary’s case, while Rita Wilson will play Hillary’s mom Ruth.
