Prior to the theft, the shoes, estimated to be worth at least US$1 million, had been kept in a Plexiglas case atop a podium inside the Judy Garland Museum in Grand Rapids, Minnesota.\r\nOn August 28, 2005, a burglar or burglars broke into the museum and smashed the case with a baseball bat. Investigators estimated that the theft took only seconds.\r\nThe search for the famous ruby heels, which Garland wore while playing Dorothy, has taken investigators to a collector\u2019s mansion in San Diego, California, and to the bottom of the Tioga Mine Pit, just outside Grand Rapids.\r\nBut the slippers reported to have been in the collector\u2019s mansion were phoneys, and divers found nothing at the bottom of the pit.\r\nThe FBI said a man approached the company that had insured the shoes about a year ago and said he had information about how the shoes could be returned. The FBI said it set up a sting operation and recovered the slippers.\r\nThe slippers\u2019 authenticity was verified by comparing them with another pair at the Smithsonian Institution\u2019s American history museum in Washington.\r\nThe FBI said it has multiple suspects in the extortion case and that the investigation continues.\r\nSeveral pairs of ruby slippers were made for the 1939 MGM film, and at least four, including the stolen pair, are known to exist.\r\nOne pair was found in the basement of MGM\u2019s wardrobe department in 1970. An anonymous buyer bought it at an auction for US$15,000 and donated it to the Smithsonian in 1979. The pair was removed from display in April 2017 to be preserved.\r\nThe Smithsonian raised nearly US$350,000 through a Kickstarter campaign to pay for the shoes\u2019 restoration. They will be back on display in October.\r\nLeonardo DiCaprio and Steven Spielberg bought one other pair for display at the Academy Museum of Motion Pictures. Another pair is owned by a private collector.\r\nThe once-missing slippers are owned by Michael Shaw, a collector who lent the slippers to the Judy Garland Museum every year.\r\nMuseum officials wanted to keep the slippers in a safe every night, but Shaw did not want other people touching the delicate artefact. So Shaw delivered the slippers himself and placed them in the Plexiglas case.\r\n\u201cWe kicked ourselves in the butt for not putting them in the safe,\u201d said Jon Miner, one of the museum\u2019s board members, in 2015. \u201cOf course, the owner was dumbfounded. And so were we.\u201d\r\nThat year, a wealthy fan of the movie volunteered to give US$1 million to the person who could help find the missing slippers.\r\nThe shoes are famously connected to the line, \u201cThere\u2019s no place like home.\u201d Toward the end of the movie, Glinda the Good Witch reveals to Dorothy that her magic slippers could take her back home.\r\n\u201cThen close your eyes and tap your heels together three times. And think to yourself, \u2018There\u2019s no place like home,\u2019 \u201d Glinda instructs Dorothy.\r\nDorothy does as she is told, chants \u201cThere\u2019s no place like home,\u201d and wakes up in her family\u2019s house in Kansas.
