A federal court in Florida has sentenced Ghanaian-American Kelvin Owusu Nkwantabisa to 17 years in prison. He masterminded a US$38 million Business Email Compromise (BEC) fraud scheme. This scheme targeted businesses and individuals globally. Nkwantabisa is 33 years old. He operated under the names Kevin Brown and KO. He led the United States branch of a crime network. This network stole over US$38 million. They used sophisticated email fraud tactics.
Court documents show how the scheme worked. Network members accessed victims' email accounts without permission. They then watched communications about business payments. The fraudsters pretended to be trusted business partners. They redirected money to their own bank accounts. Investigators stated the network used many bank accounts. They also used shell companies. This helped hide the stolen money. It also helped them avoid authorities.
Prosecutors explained Nkwantabisa's role. He managed overseas accomplices. He also arranged for bank accounts. These accounts were in various US states. He monitored the incoming fraudulent money transfers. He told others how to launder the crime proceeds. His key role led to the longest sentence in this case. Three other network members also received sentences. Leshea Moore, 29, of Georgia, got over 11 years. She created shell companies and opened fraudulent accounts. John Jouissance, 33, of Ohio, received four years. He set up shell companies and accounts for illicit money. Justice Amoh, 37, of New York, got three years. He used false identities to open accounts and process fraud.
United States Attorney Jason A. Reding Quiñones commented on the case. He said the defendants abused trust. They stole millions of dollars by exploiting business relationships. He stated these convictions send a strong message. They warn those using the US financial system for fraud. Homeland Security Investigations led the inquiry. The US Attorney's Office for the Southern District of Florida prosecuted the case.
Business Email Compromise schemes are a major global cybercrime threat. They cause billions of dollars in losses each year. This sentencing is part of a broader crackdown. US authorities are targeting transnational financial and cybercrime networks. These operations often involve victims in countries like Ghana. The sheer scale of financial loss underscores a growing digital security challenge for businesses everywhere.
