BOCA RATON, FL (BocaNewsNow.com) (Copyright © 2026 MetroDesk Media, LLC) — Four people have pleaded guilty and been sentenced for their roles in a massive business email compromise scheme that drained more than $38 million from victims across the United States and overseas. The transnational fraud operation worked by hacking into victims’ email accounts, monitoring legitimate financial conversations, and then impersonating trusted business partners to redirect payments into accounts the criminals controlled.
Kelvin Owusu Nkwantabisa, 33, of Georgia — who went by “Kevin Brown” and “KO” — led the U.S. side of the operation, coordinating with overseas co-conspirators and directing the movement of stolen funds through accounts across multiple states. He received the stiffest sentence: 17 years in federal prison.
Leshea Moore, 29, also of Georgia, set up shell companies and opened bank accounts under fake identities to launder proceeds, earning her more than 11 years behind bars. John Jouissance, 33, of Ohio, and Justice Amoh, 37, of New York, played similar supporting roles and were sentenced to four years and three years in prison, respectively.
Federal prosecutors didn’t mince words. “This was organized international fraud carried out through deception, stolen trust, and financial manipulation,” said U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida, adding that the scheme could devastate companies and individuals in a matter of hours. The case was investigated by Homeland Security Investigations and prosecuted by Assistant U.S. Attorney Quin Landon.
