The violin, which dates back to 1939, was recovered during a stolen-property seizure last week in the 600 block of Admirals Road.
The violin has been returned to its owner, an 80-year-old Duncan woman. It was stolen from her car on Aug. 8.
Police are still sorting through thousands of dollars in stolen goods found during the search, including laptops, cell phones, cameras, iPods, E-readers, guitars and credit cards.
Natasha Day, 26, Nancy Klein, 39, Michael Merrick, 31 and Theodore Turko, 36, have been charged with possession of stolen property, break and enter, and breach.
