A Houston man who spent years posing as a lovestruck suitor — and a legitimate businessman — has been handed nearly two decades in federal prison for pulling off a $4 million fraud scheme that preyed on the lonely, the trusting, and the unsuspecting alike.
Leslie Chinedu Mba, a 40-year-old Nigerian national illegally residing in Houston, was sentenced to 228 months — 19 years — in federal prison after pleading guilty to conspiracy to commit wire fraud and making false statements on immigration documents. Federal prosecutors say his operation, which ran from April 2018 to December 2023, combined the emotional manipulation of romance scams with the cold, calculated mechanics of business email compromise fraud. The result: millions lost, lives upended, and a case that federal officials say illustrates just how sophisticated — and cruel — these schemes have become.
A Double-Edged Con
Mba didn’t rely on just one playbook. On one side, he and his co-conspirators built fake romantic relationships online, using emotional hooks and manufactured intimacy to drain victims of their savings. On the other, they compromised legitimate business email accounts and deceived companies into wiring payments directly into fraudulent accounts. It’s a one-two punch that federal investigators say resulted in $4 million in total losses across the five-year operation.
Four Houston co-defendants — Grace Morisho, Rodgers Kadikilo, Kristin Smith, and Alexandra Golovko — also pleaded guilty in connection with the conspiracy, according to court documents. Mba, however, was the last to enter his plea, and prosecutors made clear he bore significant responsibility for the scheme’s scale and duration.
Preying on the Vulnerable
Who gets targeted in a romance scam? More often than not, it’s older adults — people who are widowed, isolated, or simply looking for connection in an increasingly digital world. U.S. Attorney Nicholas J. Ganjei didn’t mince words about it. “Romance scams are among the lowest and most despicable form of fraud because they prey upon the lonely and vulnerable, and disproportionately victimize senior citizens,” he said.
That’s not just rhetoric. The FBI has consistently ranked romance fraud among the costliest forms of internet crime in the country, with elderly Americans losing hundreds of millions annually. Mba’s operation fit the profile almost exactly — fake personas, manufactured affection, and a slow financial pivot once victims were emotionally invested.
An Immigration Angle That Made It Worse
Still, the fraud didn’t stop at wire transfers and broken hearts. Mba — who had already been ordered removed from the United States — allegedly attempted to arrange fraudulent marriages in a bid to secure U.S. permanent residency. That added charge, making false statements on immigration documents, carries an additional five years on top of the twenty-year maximum for wire fraud conspiracy.
It’s a brazen move, even by the standards of federal fraud cases. The man was running a multimillion-dollar scam ring while simultaneously trying to game the immigration system through fake matrimony. Federal prosecutors charged him on both fronts, and ultimately, the sentence reflected the full weight of that conduct.
The Mechanics of the Scheme
How exactly does a business email compromise work? Broadly, attackers infiltrate or spoof legitimate corporate email accounts — often those of executives or finance departments — and then impersonate them to redirect payments. A vendor expecting a routine wire transfer suddenly finds the money has vanished into an account controlled by criminals. By the time anyone notices, it’s often too late to recover the funds.
Mba’s crew ran this alongside the romance operation, layering two distinct fraud methodologies into a single, sustained criminal enterprise. The U.S. Attorney’s Office noted that the conspiracy netted its operators millions while leaving victims — both individual and corporate — scrambling to understand what had happened to their money.
What Comes Next
Mba’s sentencing is a significant moment, but it’s hardly the end of the story for this type of crime. Romance scams and BEC fraud have continued to surge in recent years, fueled by social media platforms, encrypted messaging apps, and the sheer scale of the internet. Investigators and prosecutors can win individual cases — and they did here — but the broader ecosystem that enables these schemes remains largely intact.
The Justice Department’s Southern District of Texas has made fraud prosecutions a stated priority, and this case will likely be cited as a benchmark for future sentencing arguments. Nineteen years is a long time. Whether it deters the next would-be operator is, as always, the harder question.
For the victims — the ones who sent money to someone they believed loved them, or the businesses that wired funds to an account they thought was legitimate — the sentence offers some measure of justice. But as any fraud investigator will tell you, the money rarely comes back. And the trust, once broken, takes even longer to rebuild.
