To answer about the violin - from https://tarisio.com/cozio-archive/cozio-carteggio/lost-and-found-stolen-instruments/

One of the most unusual disappearances involved the 1732 ‘Duke of Alcantara’ Stradivari, on loan to UCLA’s resident Roth String Quartet member, David Margetts, in 1967. It vanished after an evening rehearsal in Los Angeles when the violin was either stolen from Margetts’s car, or, according to a police report, “[i]t is possible the violin was left on the back of the car and fell off.” Nadia Tupica, a Spanish teacher and string player, said she found it on the side of a Los Angeles freeway. She took the violin home and placed it beneath her bed, where it remained for years until she gave it to her nephew before she died. He passed it on to his ex-wife, who had the violin taken to the Joseph Grubaugh and Sigrun Seifert violin shop in January 1994. As with the discovery of the ‘Ames, Totenberg’, red flags were raised for Grubaugh and Siefert when they confirmed the violin’s authenticity using Goodkind’s Iconography and discovered from the stolen property registry maintained at that time by the American Federation of Violin and Bow Makers that it had been listed as stolen 27 years earlier. They immediately reported their discovery to the owner, UCLA, which obtained the return of the Stradivari, but not before an ownership battle waged in court for nearly a year.
