Finally, the money would be wired back to the U.S. into accounts Onwuhara controlled. At one point he received a 40-million-euro transfer. He would further launder the money by depositing it in casinos and cashing out in checks days later. He would also buy ultra-expensive luxury cars, drive them for a few months, then ship them to Nigeria, where they would be resold at a steep markup. Onwuhara was clearing about $7 million every two weeks, according to the FBI.
