Agents from three federal agencies confiscated records, files and computers from Robbie's Marina during a Thursday morning raid of Islamorada Mayor Michael Reckwerdt's business on Stock Island and Islamorada.
Members of the Internal Revenue Service's Criminal Investigation Division, which executed the search warrant, briefly questioned Reckwerdt inside his marina office in Islamorada, as agents loaded several crates of documents into a U-Haul outside.
The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives and the FBI assisted in the operation.
No arrests were made.
IRS Special Agent Ellie Michaud, who participated in the raid, would confirm the agencies were there on "official business," but would not comment further. Her division investigates tax fraud and other financial crimes.
Reckwerdt told The Citizen he was instructed by his attorney, Jay Hershoff of Tavernier, not to speak to the press.
"I haven't done anything wrong," he said. "I'm fine."
Reckwerdt, who is serving his second term as mayor, was first elected to the five-member Village Council in 2004 and has been re-elected three times. The mayor's job is a mostly honorary position that the council bestows upon a member each year.
About 30 federal agents met at an Islamorada restaurant before swooping down at 9:30 a.m. on the bayside marina at Mile Marker 77.5.
While agents gathered up files and records, tourists fed the tarpon from the docks -- a popular Robbie's Marina attraction -- unaware of what was going on just a few yards away.
A yellow police line was set up around the office building in front of the marina's main entrance and some agents asked that their faces not be photographed.
Authorities later repeated the exercise at the Stock Island location.
Reckwerdt is listed as president or manager of about a dozen businesses registered with the state, most of which are associated with his two marinas. Among them are Robbie's Investment LLC, Rent-A-Boat Inc. and Flamingo Air of Florida Keys.
Financial investigations are complex and can take more than a year, according to the IRS website.
Among the 163 convictions during the past fiscal year, those who have been sentenced during that time averaged 24 months of incarceration in federal prison.
