Tampa police are searching for three suspects who used hammers Tuesday to smash open a case at a jewelry store and took off with $300,000 in Rolex watches. Authorities are studying surveillance footage from the Mayors Jewelry Store. The suspects were in and out in less than a minute and took about a dozen watches with them, MyFoxTampaBay.com reported. The smashing of the case sounded similar to gunshots, causing a panic among shoppers at the International Plaza Mall, where the store is located.
