A pair of ruby slippers that were used in The Wizard of Oz have been recovered in a sting operation after being stolen from a Minnesota museum 13 years ago. The slippers were on loan from a memorabilia collector to the Judy Garland Museum in Grand Rapids, the hometown of the late actress who played Dorothy, when someone climbed in through a window and broke into a display case before making off with the shoes. The ruby slippers were insured for $1 million. The FBI said a man told the insurer last year that he could help get the shoes back, and after a nearly year-long investigation, they were recovered in a July sting operation in Minneapolis. No one has been arrested or charged so far, but the FBI said they have multiple suspects and are continuing to investigate. Three other pairs of ruby slippers that Garland wore in the movie are currently in the possession of the Academy of Motion Picture Arts and Sciences, the Smithsonian and a private collector.
