From: Photo Flash: BODY OF PROOF's 'Committed,' Airing 4/23

On BODY OF PROOF's upcoming episode, titled 'Committed,' a schizophrenic teenage girl at a mental institution is found murdered. When Megan and Tommy interview a young patient named Darby, who seems extremely sane and lucid, she tells them that she saw the killer climb down from a heating vent in the ceiling, but most shocking of all -- he meant to kill her, not the actual victim. Could the killer be Dr. Malcolm (Craig Bierko), the ward director, who is obstructing their investigation? 'Body of Proof' airs TUESDAY, APRIL 23 (10:01-11:00 p.m. ET) on ABC.
