The Willer Tomaz Money Laundering Probe: The Federal Police aren't going after him for his political opinions. He's tied to a massive money-laundering probe with lawyer Willer Tomaz, who moved R$ 5 billion through online betting sites (Blaze) and pulled out R$ 200 million. PF investigators found Flávio listed as a privileged "master" user on an offshore account belonging to Tomaz's firm (Alcazar Holdings), alongside another R$ 130M moving through shell accounts.
Rachadinha & Real Estate Laundering: Before the Senate, he spent years running a public-salary embezzlement scheme (rachadinha) in Rio through his fixer Fabrício Queiroz, laundering stacks of physical cash through a chocolate shop and shady real estate deals. He only got off because sympathetic judges threw out the financial evidence on a jurisdictional technicality.
Rio's Paramilitary Militias: Through that exact same cabinet scheme, Flávio put the mother and wife of Adriano da Nóbrega—head of the Escritório do Crime death squad—on the public payroll as ghost employees, and personally honored Nóbrega with Rio's highest medal from his prison cell.
