Nigerian Man Sentenced To 19 Years Imprisonment In US For $4m Wire Fraud, Romance Scam, Fraudulent Marriage Attempts

Leslie Chinedu Mba, a 40-year-old Nigerian man living illegally in Houston, has been sentenced to nearly 20 years in federal prison for his involvement in a romance scam and a business email compromise scheme.

The U.S. Attorney Nicholas J. Ganjei, announced this in a press statement issued by the Department of Justice on Thursday, February 26, 2026.

Mba pleaded guilty to conspiracy to commit wire fraud and conspiracy to commit false statements in immigration documents December 4, 2025.

U.S. District Judge David Hittner has now ordered Mba to serve 228 months in federal prison. 

Not a U.S. citizen, he is expected to face removal proceedings following his imprisonment. 

At the hearing, the court heard that victims were defrauded of over $4 million. 

Out of all the frauds perpetrated by Leslie Mba and his co-conspirators, their weaponization of romance scams to deliberately target vulnerable and elderly Americans is most disturbing,” said FBI Houston Special Agent in Charge Jason Hudson. 

“Romance scams cruelly manipulate trust, callously exploit the fear of loneliness, and leave victims both financially devastated and emotionally shattered. The FBI will continue to combat fraudsters whose schemes leave a wake of misery behind.”

From April 2018 to December 2023, Mba and others inside and outside of the United States carried out business email compromise and romance scams targeting unsuspecting victims.

The schemes began overseas, where co-conspirators gained unauthorized access to business email accounts and redirected payments to fraudulent bank accounts.

Victims believed they were sending money to legitimate businesses, but Mba and others instead funneled the funds to accounts they controlled. 

Mba and others acted as money mules, opening or using existing bank accounts to collect and move proceeds from the fraud.

Additionally, Mba tried to obtain U.S. permanent residency through multiple fraudulent marriages after his initial application was denied and he was ordered to be removed from the country.

The scheme resulted in a total loss of $4 million.

Four others had also previously pleaded guilty Grace Morisho, 30, Rodgers Kadikilo, 30, Kristin Smith, 38, and Alexandra Golovko, 36, all of Houston. 

Morisho, Kadikilo and Smith received sentences ranging between 15 to 25 months while Golovko received five years probation.

Mba will remain in custody pending transfer to a Federal Bureau of Prisons facility to be determined in the near future.

FBI conducted the investigation with the assistance of Houston Police Department. Assistant U.S. Attorney Alexander Alum prosecuted the case.
