Stuart Lynn Dunn made an unauthorized departure Saturday around 8 p.m. from a secured mental health facility in Pomona where he was being confined to post-release supervision, Los Angeles County Sheriff’s Department Lt. Martin Rodriguez said. Dunn was previously convicted of stalking Kunis, when he allegedly violated a restraining order by repeatedly trying to contact the “Black Swan” actress and temporarily lived in a vacant home she owned, the Los Angeles Times reported in 2012.
