Stradivari violins are some of the most sought after and valuable instruments in the world. With violins from his golden period of 1700 to 1725, it is a rare honor to lay your eyes, or hands, on one. That's why the FBI was faced with a one-of-a-kind case when in January 2014, Milwaukee Symphony Orchestra concertmaster Frank Almond was attacked and robbed of the Lipinski Strad-a 1715 Stradivarius violin valued at over $6 million. The Milwaukee Police Department and FBI jumped swiftly into action, aware of what was at stake of being lost-and that time was of the essence.
