If you’re planning a musical heist, it doesn’t get bigger than stealing a Stradivarius. That’s why Salah Salahadyn spent a decade plotting the theft of “Lipinski,” a 299-year-old violin worth close to six million dollars. The first part of his plan was ingeniously simple — he used a Taser to disable the concertmaster of the Milwaukee Symphony Orchestra, grabbed his violin case and ran. Unfortunately for him, the second part of the plan didn’t exist. Milwaukee’s police amped up, an accomplice blabbed, Salahadyn was arrested and the Lipinski was returned, safe and sound.
