Charged were Evelyn Minott, the chamber's former executive director of finance, and Freddy Luna, former finance manager, The Miami Herald reported Thursday.

Both face fraud and racketeering charges. Minott is charged with three counts of money laundering.

The Miami-Dade County State Attorney's Office said the low-tech scheme involved the use of carbon copies of checks, an old typewriter with a white correcting ribbon and a rubber signature stamp.

"This is the old fashioned method," said State Attorney Katherine Fernandez-Rundle. "The chamber is made up of some of the best and brightest. And they, too, can be a victim."

She said the investigation in the case would continue.
