Orlando Man Pleads Guilty to His Role in Years-Long Off-the-Books Payroll Scheme

A Honduran national pleaded guilty today to conspiring with others as part of a years-long off-the-books payroll scheme that caused more than $38 million in losses to the U.S. government.

According to court documents and statements made in court, Mario Lisandro Flores Moradel operated an illegal, off-the-books cash payroll system for construction workers to avoid paying employment taxes to the IRS and to defraud workers' compensation insurance companies. Through the scheme, Flores and his co-conspirators also facilitated the employment of illegal aliens impermissibly working in the United States.

From 2015 to 2022, Flores and his co-conspirators used a series of shell companies to run an unlicensed check cashing and cash courier service business. These businesses cashed approximately $89 million in checks from subcontractors in the construction industry, charging them a percentage of the dollar amount of the checks they cashed as a fee for this service. The scheme allowed construction contractors and subcontractors to pay their workers in cash without making required payroll taxes and without regard to whether the workers were legally authorized to work in the United States. Flores and others also caused the filing of false tax documents with the IRS to conceal the scheme. Of the total loss amount, Flores admitted to causing a tax loss to the United States of more than $9.4 million.

Flores pleaded guilty to one count of conspiracy to defraud the United States and one count of conspiracy to operate an unlicensed money transmitting businesses. He is scheduled to be sentenced on June 24. He faces a maximum penalty of five years in prison for each count of conspiracy. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

Several of Flores' co-conspirators previously pleaded guilty for their roles in the scheme. Michael Mayorga and Francisco Alvarez pleaded guilty on May 22, 2025. Iris Villafranca and Osman Zapata pleaded guilty on Oct. 9, 2025.
