Honduran National Sentenced to 8 Years in $89 Million Payroll Fraud Scheme Involving Construction Workers

Mario Flores, a Honduran national present in the United States without legal status, was sentenced to eight years in federal prison for his role in a fraudulent payroll scheme that ran from 2015 to 2022, according to the Department of Justice.

The mechanics were straightforward but sprawling. Flores and his co-conspirators created a series of shell companies that operated an unlicensed check-cashing and cash-courier business. Those companies cashed roughly $89 million in checks from construction subcontractors, charging a percentage fee for the service. The cash went directly to workers, bypassing payroll tax withholding entirely.

By paying workers in cash, construction contractors avoided verifying whether those workers were legally authorized to work in the United States. Flores also filed false documents with the IRS to conceal the scheme's operations, according to court records cited by the DOJ.

The fraud didn't stop there. Flores and his associates also defrauded workers' compensation insurers by leasing out insurance certificates to contractors and submitting false information about how many workers were covered and how much they were paid. This represented a separate layer of financial crime on top of the tax fraud.

Government's Assessment

Assistant Attorney General Colin McDonald put the taxpayer damage at more than $38 million. "This case exposes how unchecked illegal immigration fuels widespread payroll tax fraud and underground economies that harm American workers and taxpayers," McDonald said in a statement reported by Breitbart News.

Homeland Security Investigations Special Agent in Charge John Condon added that HSI "is committed to protecting the integrity of our financial system and enforcing our nation's laws."

Flores pleaded guilty to two counts: conspiracy to defraud the U.S. government and conspiracy to operate an unlicensed money transmitting business.

Co-Conspirators

Flores was not alone. Three co-defendants, Iris Villafranca, Osman Zapata, and Francisco Alvarez, were sentenced before him. Their sentences ranged from four to 17 years in federal prison, according to the DOJ.

The 17-year sentence at the top of that range is notably steep for a financial fraud case, suggesting at least one co-conspirator's conduct or criminal history warranted a significantly harsher outcome than Flores's eight years.

Worker Exploitation and Labor Protections

The workers at the bottom of this scheme were also its victims in a real sense. Cash-paid construction workers, regardless of immigration status, had no payroll protections, no workers' compensation coverage they could actually rely on, and no documented employment history. If they were injured on the job, the fraudulent insurance certificates their employers carried were worthless. Nobody in this case appears to have been charged specifically with protecting those workers' labor rights, and no source addresses whether any restitution flows to them.

This concern coexists with the documented tax fraud and immigration law violations. But it represents a factual gap in the enforcement picture: the contractors who hired these workers and knowingly used Flores's cash-payment system to avoid scrutiny are not named in the DOJ announcement as defendants. Whether those contractors faced or will face separate charges remains an open question based on the available sourcing.

The Scheme's Economic Structure

The scheme worked because multiple parties had financial incentives to stay inside it. Contractors got cheap labor with no payroll overhead and no immigration paperwork. Flores and his network collected percentage fees on $89 million in transactions. Workers got paid, even if off the books.

The IRS and state tax agencies lost withholding revenue. Workers' comp insurers paid out on fraudulent policies. Legitimate construction businesses competing for the same contracts faced higher costs because they were actually withholding taxes and verifying employment eligibility.

Underground payroll schemes don't just steal from the government. They create a cost disadvantage for law-abiding competitors and can suppress wages across an entire sector.

Sourcing Note

The sole source for this story is Breitbart News, which reported the DOJ's press release and statements. The DOJ's underlying case documents are the primary factual record. No major wire services or center-left outlets had independently covered this sentencing in available sources as of June 25, 2026. The core facts, names, dollar figures, and guilty plea come from court records and DOJ statements, not from Breitbart's editorial framing, so the factual basis is solid. Breitbart's framing emphasizes immigration enforcement. The DOJ's own language is notably similar, which means the editorial tilt in this case happens to track the government's stated position.

The unresolved question is whether federal prosecutors pursued or are pursuing the construction contractors who used Flores's service. The DOJ announcement names and sentenced the operators of the cash scheme but says nothing about the subcontractors who paid for it.
