Sinead O'Connor has reportedly gone missing and has been classified as "suicidal" by Chicago-area police after she went on a bicycle ride Sunday afternoon and never returned. The Irish singer-songwriter was wearing a black parka, black leather pants, and a sweatshirt at the time she disappeared; her bicycle has a pink basket. O'Connor was also considered at risk in November after leaving an angry note directed at her family. She received medical treatment following that event.
