Two Nigerians And One Other Convicted In U.S. For $4.9M Stolen Identity Tax Fraud Scheme

Two Nigerian nationals, Imafedia Adevokhai and Osazuwa Peter Okunoghae, alongside one other, have been sentenced to US federal prison for their involvement in a tax refund fraud scheme.

The Acting U.S. Attorney for the Eastern District of Texas, Abe McGlothin, Jr. announced this in a statement obtained on Sunday, April 6.

Imafedia Adevokhai, 47, of Alpharetta, Georgia, pleaded guilty to money laundering on February 15, 2023, and was sentenced to 46 months in federal prison by U.S. District Judge Robert W. Schroeder, III on April 2, 2025. Adevokhai was ordered to pay $90,380.60 in restitution and $3500 in forfeiture.

Michael Martin, 52, of Texarkana, Texas, pleaded guilty to conspiracy on February 14, 2023, and was sentenced to 18 months in federal prison by Judge Schroeder on November 21, 2023. Martin was ordered to pay $90,380.60 in restitution and $121,623.41 in forfeiture.

Osazuwa Peter Okunoghae, 46, of Houston, pleaded guilty to money laundering conspiracy on November 12, 2019, and was sentenced to 78 months in federal prison by Judge Schroeder on January 13, 2022. Okunoghae was ordered to pay $451,117.63 in restitution and $451,117.63 in forfeiture.

"The Eastern District of Texas is committed to prosecuting individuals who participate in schemes to steal personal information, prepare and file fraudulent tax returns, and launder the proceeds,” said Acting U.S. Attorney Abe McGlothin, Jr. “Crimes like these affect all of us, the individual victims whose identities are stolen and used to file fraudulent tax returns, the taxpayers, who are left with the bill, and our financial institutions, which are manipulated and misused to launder the proceeds.”

“Adevokhai, Martin, and Okunoghae, along with others, created a complex scheme to steal the tax refunds of law-abiding U.S. taxpayers through stolen identity refund fraud,” said Christopher J. Altemus Jr., special agent in charge of the IRS Criminal Investigation’s Dallas Field Office.

“The women and men of IRS-CI did an outstanding job of uncovering this fraudulent activity and bringing the individuals to justice. Their sentences should be a warning to anyone who would try to defraud the U.S. Government or prey on law-abiding taxpayers.”

According to information presented in court, Adevokhai, Martin, Okunoghae, and others were involved in a multi-year stolen identity refund fraud (SIRF) conspiracy involving the theft of victims’ personal identifying information and the use of the stolen information to file fraudulent tax returns.

The total tax refunds claimed by the fraudulent returns was $4,945,886, and the U.S. Department of Treasury, Internal Revenue Service, suffered at least a $390,220.40 loss.  

Adevokhai was involved in the preparation and filing of many of the fraudulent tax returns. Okunoghae and Martin were involved in the laundering of the stolen funds. To that end, they worked together and with others who would transfer fraud proceeds through United States financial accounts and ultimately to foreign financial accounts. The investigation connected Adevokhai, Martin, and Okunoghae to dozens of victims whose taxpayer identities were stolen.

In January 2019, individuals from three states and other individuals from Nigeria were charged for their roles in the conspiracy.

One of the Department of Justice Tax Division’s top priorities is prosecuting individuals who use stolen identities to steal money from the United States Treasury by filing fraudulent tax returns. SIRF schemes threaten to disrupt the orderly administration of the income tax system for law-abiding taxpayers and have cost the United States Treasury billions of dollars.

The case was investigated by the Internal Revenue Service-Criminal Investigation (IRS-CI) and prosecuted by Assistant U.S. Attorneys Nathaniel C. Kummerfeld and Sean Taylor.
