On February 15, 2003, a group of thieves broke into an allegedly airtight vault in the international diamond capital of Antwerp, Belgium and made off with over $108 million dollars worth of diamonds and other valuables. They did so without tripping an alarm or injuring a single guard in the process. Although the crime was perfect, the getaway was not. The police zeroed in on a band of professional thieves fronted by Leonardo Notarbartolo, a dapper Italian who had rented an office in the Diamond Center and clandestinely cased its vault for over two years. The “who” of the crime had been answered, but the “how” remained largely a mystery.
