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.

Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division and U.S. Attorney Gregory W. Kehoe for the Middle District of Florida made the announcement.

IRS Criminal Investigation is investigating the case with assistance from Homeland Security Investigations. ICE ERO Miami (Orlando sub-office), Florida Highway Patrol, U.S. Customs and Border Protection, U.S. Marshals Service, State Department and the Florida Department of Law Enforcement have assisted in arrest operations.

Russian Citizen Sentenced to Prison for Hacking into U.S. Companies and Enabling Major Cybercrime Groups to Extort Tens of Millions of Dollars

A court in the Southern District of Indiana today sentenced a Russian citizen, Aleksei Volkov, to 81 months in prison for assisting major cybercrime groups, including the Yanluowang ransomware group, in carrying out numerous attacks against U.S. companies and other organizations. Volkov facilitated dozens of ransomware attacks throughout the United States, causing over $9 million in actual losses and over $24 million in intended losses. Volkov was indicted for this activity in both the Southern District of Indiana and Eastern District of Pennsylvania. Police in Rome, Italy, then arrested Volkov, and he was extradited to the United States. He pleaded guilty to charges from both indictments.

According to court documents, Volkov, 26, of St. Petersburg, Russia, was an “initial access broker,” that is, a person who specializes in gaining unauthorized access to computer networks and systems of corporations and organizations and selling that access to other cyber threat actors such as ransomware groups. Volkov found vulnerabilities in computer networks and systems, identified ways to access those networks and systems without authorization, and sold that illicit access to conspirators who were also cybercriminals.

Volkov’s co-conspirators then used the access Volkov provided to infect the affected computer networks and systems with malware. This malware encrypted the victims’ data and prevented the victims from accessing it, damaging their business operations. The conspirators then demanded that the victims pay them a ransom in cryptocurrency — sometimes in the tens of millions of dollars — in exchange for restoring the victims’ access to the data and promising not to publicly disclose the hack or release victims’ stolen data on a “leak” website. In some cases, the victims paid the ransom and in others the conspirators posted the victims’ confidential data on the leak site. If the victims paid the ransom, Volkov received a share of the money.

On Nov. 25, 2025, Volkov pleaded guilty to four counts from the Southern District of Indiana indictment, namely, unlawful transfer of a means of identification, trafficking in access information, access device fraud, and aggravated identity theft; as well as two counts from the Eastern District of Pennsylvania indictment, namely, conspiracy to commit computer fraud and conspiracy to commit money laundering after the  two cases were consolidated in the Southern District of Indiana. As part of his plea, Volkov admitted that he and his co-conspirators hacked into numerous victims’ computer networks, stole their data, deployed ransomware, demanded payment in cryptocurrency to exchange for restoring access to the data, and divided the ransom payments among themselves. In fact, they demanded tens of millions of dollars in ransom and received millions. Volkov agreed to pay full restitution to victims including at least $9,167,198.19 to known victims to compensate them for their actual losses as well as to forfeit equipment he used for his crimes.

Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division, U.S. Attorney Thomas E. Wheeler II for the Southern District of Indiana, U.S. Attorney David Metcalf for the Eastern District of Pennsylvania, Special Agent in Charge Timothy O’Malley of the FBI Indianapolis Field Office, and Special Agent in Charge Wayne A. Jacobs of the FBI Philadelphia Field Office made the announcement.

The FBI is investigating the case.

Miller for the Southern District of Indiana, and Assistant U.S. Attorney Sarah Wolfe for the Eastern District of Pennsylvania are prosecuting the case. The Justice Department’s Office of International Affairs worked with the Government of Italy to secure the arrest and extradition from Italy of Volkov.

Guilty Pleas


United States v. Willam Randolph Hires

  • No. 3:25-CR-00784 (District of New Jersey)
  • ECS Senior Trial Attorney RJ Powers
  • AUSA Jessica Ecker

On February 9, 2026, William Randolph Hires pleaded guilty to a one-count Information charging him with illegally importing hydrofluorocarbons (HFCs) in violation of the American Innovation and Manufacturing Act (AIM Act) and the Clean Air Act (42 U.S.C. §§ 7675, 7413). Sentencing is scheduled for June 17, 2026.

Hires was the chief executive officer of Extreme Residential, a Georgia-based heating, ventilation, and air conditioning company. In April 2022, Extreme Residential illegally imported 500 cylinders of HFCs into the United States from Peru. Over the next several months, U.S. Environmental Protection Agency (EPA) officials explained to Hires’s employees that, under the AIM Act and its implementing regulations, Hires’s company could not lawfully import the HFCs into the United States because it failed to obtain the required allowances from EPA. In a July 2022 email to one of Hires’ s employees, an EPA official stated, “it is not possible to import bulk HFCs without consumption allowances.”

Company employees relayed this information from the EPA to Hires several times. On one occasion, an employee forwarded Hires an email from an EPA official that stated, “[t]he HFC you listed (R-410A) is a regulated substance. So, if you do not have allowances, you cannot import those bulk HFC refrigerants.” Hires nevertheless instructed his employees to illegally import the HFCs into the United States. Hires stated to his employees: “ [y]eah you have to be careful what agencies you’ re reaching out to because the EPA . . . can create a hassle and they can hold our stuff up in customs there[.]” In a subsequent email, Hires instructed his employees to “get [the HFCs] on the ship and get it out to sea . . . don’ t care what it takes[.]” Hires later told his employees via email: “Do not call the EPA please do not.”

Extreme Residential was administratively dissolved and will not be prosecuted.

United States v. Sebastian Cruz-Amaya

  • No.7:25-CR-02953 (Southern District of Texas)
  • AUSA Roberto Lopez, Jr.

On February 24, 2026, a court sentenced Sebastian Cruz-Amaya to 24 months’ incarceration, with no supervised release. The defendant pleaded guilty to smuggling reptiles from the United States to Mexico (18 U.S.C. § 554(a)).

In October 2025, Cruz-Amaya attempted to enter Mexico from Texas with a number of exotic animals concealed within his vehicle. Upon questioning, Cruz-Amaya told officials that he was exporting the animals on behalf of another individual in Mexico and expected to be paid approximately $500-$600. Cruz-Amaya also said he had transported animals over the last five years for the same individual, estimating he had made more than 100 trips. Over this period of time, Cruz-Amaya charged approximately $120,000, netting $40,000 for himself.

Investigators found numerous communications between Cruz-Amaya and others on his cell phone discussing the receipt and export of wildlife as well as various invoices for animals. 

In his vehicle, authorities found an invoice dated October 21, 2025, from a company in Ohio that had shipped approximately 54 snakes to a UPS store in McAllen, Texas, for delivery on October 22, 2025. The animals recovered from Cruz-Amaya’s vehicle included more than 100 snakes, lizards, frogs, spiders, centipedes, and a turtle. Wildlife agents identified several species listed under Appendix II of the Convention on International Trade in Endangered Species, as well as at least one species, the Indian Star Tortoise, that is listed on Appendix I.

Agents served subpoenas on various vendors and discovered members of the conspiracy were involved in the unlawful exportation of at least $580,000 worth of wildlife, as well as an additional 1,088 snakes with undetermined value, from Hidalgo County, Texas, to Mexico since 2020.

Homeland Security Investigations; the Bureau of Alcohol, Tobacco, Firearms, and Explosives; and the U.S. Fish and Wildlife Service Office of Law Enforcement conducted the investigation.
