Spanish police last week launched an investigation into the disappearance of $125,000 worth of diamond jewelry last seen in the possession of Winona Ryder. The actress, who was convicted of shoplifting in 2001, borrowed the Bulgari bracelet and ring to wear to a party, and later reported them missing, saying she had given them to the staff at her Madrid hotel for safekeeping. Hotel executives said they combed surveillance tapes and found no footage of Ryder handing over the jewels.
