Texas Couple Pleads Guilty for Operating Website Selling Smuggled Pesticides and Veterinary Drugs

Thao Duong of Garland, Texas, pleaded guilty today for conspiring to smuggle and sell unregistered pesticides and misbranded veterinary drugs. Duong’s husband, Lam Mai, also pleaded guilty for conspiring to sell unregistered pesticides and misbranded veterinary drugs. The couple operated a website selling those drugs and pesticides, which had been smuggled into the United State from Mexico. They are scheduled to be sentenced on June 9.

“Stopping transborder crime is a top priority for the Department of Justice,” said Principal Deputy Assistant Attorney General Adam Gustafson of the Justice Department’s Environment and Natural Resources Division (ENRD). “We will continue to investigate and prosecute those who flout our customs laws and endanger the health and safety of Americans.”

“No one should profit from bringing illegal chemicals into the United States and poisoning American communities,” said Assistant Administrator Jeffrey A. Hall for EPA’s Office of Enforcement and Compliance Assurance. “Illegal Mexican pesticides and animal steroids are a toxic combination. The guilty plea in this case underscores the importance of the cooperative efforts of federal, state, and local agencies to disrupt smuggling operations and secure our nation’s borders from foreign harm.”

“This case highlights the need to protect unwitting consumers from dangerous, misbranded products smuggled in from foreign sources at the expense of the health and safety of our citizens,” said U.S. Attorney Ryan Raybould for the Northern District of Texas. “We applaud the diligent work of our law enforcement partners to interrupt these illegal practices and punish those who commit them.”

“Smuggling prohibited and misbranded products into the United States, and then selling them to unsuspecting consumers, greatly endangers public health,” said Acting Special Agent in Charge Jonathan Lamb of the Food and Drug Administration (FDA) Office of Criminal Investigations, Kansas City Field Office. “The FDA will continue working with our federal government partners to bring to justice anyone who carries out these illegal actions.”

According to filings and evidence presented in court, in approximately 2011, Duong began using various online platforms to sell animal care products to customers throughout the United States. The products she sold were used primarily by people engaged in rooster fighting ventures. Duong was not a veterinarian and did not require customers to provide veterinary prescriptions to purchase veterinary drugs. She also sold products such as Cipio Vet, Baytril Max, and Caterrol, which are produced in Mexico and not approved by the FDA for use in the United States. In 2017, she added the pesticides Taktic and Bovitraz to her inventory. Taktic and Bovitraz are not registered with the EPA for sale or use and cannot be sold legally in the United States.

In 2018, Duong started a website which she used as her primary means of selling and distributing veterinary drugs and pesticides. After launching the website, Duong entered into agreements with several co-conspirators to purchase veterinary drugs and pesticides that she knew had been smuggled into the United States from Mexico.

The smuggled pesticides and veterinary drugs were brought into the United States through the Calexico Port of Entry in Imperial County, California, and placed in storage units near the border. Duong’s co-conspirators then shipped the products from California to Texas. Between 2018 and 2022, Duong obtained approximately $2.4 million worth of smuggled merchandise from her co-conspirators.

Lam Mai was the shipping manager for the website. After orders were received he packaged the pesticides and veterinary drugs and distributed them to customers throughout the country using the United States Postal Service and other shippers.

According to the EPA, the active ingredient in the pesticides Taktic and Bovitraz is amitraz, which is toxic to bees if released into hives, and then ultimately to humans when it ends up in honey, honeycomb, and beeswax. Misuse of amitraz-containing products in beehives can result in exposures that could cause neurological effects and possibly reproductive effects in humans from the consumption of contaminated honey. Signs of neurotoxicity from exposure to amitraz have been documented in multiple animal species and include central nervous system depression, decrease in pulse rate, and hypothermia.

The EPA and FDA investigated the case, with assistance from Homeland Security Investigations and the United State Postal Inspection Service.

Trial Attorney Lauren D. Steele of ENRD’s Environmental Crimes Section is handling the prosecution with assistance from Assistant U.S. Attorney Vincent J. Mazzurco for the Northern District of Texas. 

Health Care Executive Pleads Guilty to Kickback Scheme in Vermont

A Florida businesswoman pleaded guilty today to an information in the District of Vermont for participating in a conspiracy to pay health care kickbacks.

According to court documents, Evelyn Herrera, 62, of Loxahatchee, Florida, owned a durable medical equipment company called Merida Medical Supplies Inc. (Merida). After obtaining the identities of individuals residing in Vermont, across New England, and elsewhere in the United States, Herrera, using Merida, submitted fraudulent claims to Medicare for wrist, knee, and back braces that were never requested or received by patients. In total, Merida fraudulently billed Medicare approximately $6.5 million, and Medicare paid Merida approximately $2.8 million based on those claims.

As part of the scheme, Herrera tried to hide the source of the funds generated fraudulently by Merida. For example, she transferred more than $300,000 in fraud proceeds to a cryptocurrency exchange and sent another $125,000 of illicit funds via international wire transactions for the purchase of a property in Tulum, Mexico. After the Centers for Medicare and Medicaid Services issued a payment suspension letter to Merida for suspected fraud, Herrera withdrew large amounts of cash from a bank and transferred some of the funds to benefit herself and members of her family.

Herrera is scheduled to be sentenced on May 11, and faces a maximum penalty of five years in prison.

Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division; Special Agent in Charge Roberto Coviello of the Department of Health and Human Services, Officer of Inspector General (HHS-OIG), and Special Agent in Charge Ted E. Docks of the FBI made the announcement.

HHS-OIG and FBI are investigating the case.

Trial Attorneys Sarah Rocha, Thomas Campbell, and Tiffany Wynn of the Justice Department’s Fraud Section are prosecuting the case.

The Fraud Section leads the Criminal Division’s efforts to combat health care fraud through the Health Care Fraud Strike Force Program. Since March 2007, this program, currently comprised of nine strike forces operating in 27 federal districts, has charged more than 5,800 defendants who collectively have billed federal health care programs and private insurers more than $30 billion. In addition, the Centers for Medicare & Medicaid Services, working in conjunction with the Office of the Inspector General for the Department of Health and Human Services, are taking steps to hold providers accountable for their involvement in health care fraud schemes.

Two Plead Guilty to Drug-Involved Murder

Two individuals connected to a drug trafficking organization (DTO) pleaded guilty last week to charges stemming from a 2022 murder in Miami. Tsvia Kol, 37, of Hallandale, Florida, and Jimmy Sanchez, 37, of Spring Valley, California, face up to life imprisonment for their crimes.

“This case illustrates that drugs and violence go hand in hand,” said Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division. “As part of their drug operation, these defendants shipped large amounts of methamphetamine, and when they thought the victim stole their product, they killed him in cold blood. The Criminal Division will continue prosecuting serious drug crimes, with and without violence involved, to protect the public from the grave consequences that occur, like they did here.”

“These guilty pleas lay bare the deadly reality of drug trafficking,” said U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida. “This was a cold-blooded murder driven by the drug trade, where intimidation and greed turned narcotics trafficking into violence and death. Our Office will use every federal tool available to dismantle these organizations and hold accountable anyone who chooses violence as a means of doing business.”

“This transnational investigation is the result of law enforcement partners pulling resources and working together to bring these criminals to justice,” said Acting Special Agent in Charge Kevin Bobbitt of the Drug Enforcement Administration (DEA) Miami Field Division.

“Illegal drug trafficking inherently results in violence which is inflicted by the criminal drug networks that distribute them,” said Special Agent in Charge Brett Skiles of the FBI Miami Field Office. “The impact on our communities is real and devastating. The FBI is committed to working with our federal, state, and local partners in our common goal of making our communities safe by combating drug-related violence.”

“Postal Inspectors are committed to maintaining the safety of the community and employees of the U.S. Postal Service,” said Inspector in Charge Bladismir Rojo of the U.S. Postal Inspection Service, Miami Division. “We will continue to work with our law enforcement partners to pursue anyone who uses the nation’s mail system for illegal or dangerous use.”

Court documents and statements made in court show that the defendants admitted to murdering a Miami man (the victim) in connection with a missing package containing about 11 pounds of methamphetamine, the street value of which totaled approximately $90,000. Kol and Sanchez believed that the victim stole the package of drugs. In retaliation, Kol and Sachez met the victim in a hotel room. Kol armed Sanchez with a firearm. While inside the room, the victim called 911 and attempted to provide his location, but the audio of the call portrayed a physical altercation ensuing and gunshots firing. Sanchez admitted that he shot and killed the victim in the hotel room and left his body, which was not discovered until the following morning. Hotel security footage revealed Kol and Sanchez fleeing the property after the murder.

As part of their plea agreements, the defendants admitted that they each committed the murder and that they distributed almost 11 pounds of methamphetamine. Their sentencing hearings are scheduled to take place later this year.

The DEA, the FBI, the U.S. Postal Inspection Service, Immigrations and Customs Enforcement Homeland Security Investigations (HSI), the Miami Dade Sherriff’s Office, the Hialeah Police Department, and the San Diego County Sheriff’s Office investigated this case.

Trial Attorney Jessica A. Massey from the Criminal Division’s Violent Crime and Racketeering Section and Assistant U.S. Attorneys Monique Botero and Jacob Koffsky for the Southern District of Florida are prosecuting the case.

This case is part of the Criminal Division’s Violent Crime Initiative to prosecute violent crimes in Miami. The Criminal Division and the U.S. Attorney’s Office for the Southern District of Florida have partnered, along with local, state, and federal law enforcement agencies, to confront violent crimes committed by gang members and associates through the enforcement of federal laws and use of federal resources to prosecute offenders and prevent violence.
