Four people were sentenced to prison for their roles in one of the biggest heists in Florida history — a brazen daylight armed robbery of $7.4 million in cash from a warehouse near Miami International Airport.

The cash was part of an $80 million deposit shipped by a bank in Frankfurt, Germany, to the Federal Reserve Bank branch in Miami on Nov. 6, 2005. The masked robbers, at least one armed with a gun, ordered warehouse and security personnel to lie on the floor while they loaded bags of currency into a pickup truck that had pulled into one of the cargo bays.

The ringleader, Karls Monzon, and getaway driver, Jeffrey Boatwright, were each sentenced to more than 17 years in prison on Friday. A former Brink's security guard who provided inside information for the robbery, Onelio Diaz, was sentenced to 16 years.

Monzon's wife, Cinnamon Monzon, was sentenced to nearly 3 years for being an accessory, including helping her husband conceal about $80,000 in vacuum-wrapped cash in the attic of their home.

Some has been recovered from various sites in Miami, including money that was buried outside at least one home. More than $6 million remains unaccounted for, according to the FBI.

"This is, if not the biggest, one of the biggest armed robberies in Florida history," said Anthony Lacosta, the chief federal prosecutor on the case.
