Texas Man Sentenced to 11 Years in Prison and Ordered to Pay $2M Fine for Conspiring to Monopolize International Transit Industry, Fix Prices, Extort $9.5M, and Launder Money

Carlos Martinez, 39, of Mission, Texas, was sentenced today to 11 years in prison and a fine of $2 million for his conduct in a long-running and violent conspiracy to monopolize the transmigrante forwarding agency (TFA) industry in the Los Indios, Texas, border region. Martinez and his co-defendants controlled the TFA industry through monopolization and extortion of competitors.

Transmigrantes transport used vehicles and other goods from the United States through Mexico for resale across Central America. There are only a few locations where transmigrantes are permitted to cross from the United States into Mexico, one of those being the Los Indios Bridge in Texas. TFAs are U.S.-based businesses that provide services to transmigrante clients, including helping clients complete the customs paperwork required to export vehicles into Mexico. According to court documents and statements made in court, Martinez and his co-defendants fixed prices for TFA services and created a centralized entity known as “The Pool” to collect and divide revenues among the conspirators, limit competition from other agencies, and increase prices for their services.

“The defendants exploited hardworking professionals in the freight forwarding business using extortion and illegal price-fixing schemes to manipulate the market and inflate the cost of moving goods,” said Matthew R. Galeotti, Head of the Justice Department’s Criminal Division. “The lead defendant’s 11-year prison sentence reflects the serious economic harm inflicted on the business community along the southern border. The Criminal Division will continue to pursue and prosecute those who threaten fair competition and the integrity of our markets.”

“Today’s sentence reflects the significant danger and harm the American people face from violent and extortive actions aimed at fixing prices and monopolizing the market for essential services in the Texas border region,” said Assistant Attorney General Abigail Slater of the Justice Department’s Antitrust Division. “The Antitrust Division will continue to aggressively pursue violent criminals who aim to corrupt America’s free markets and advocate for their incarceration.”

“Price fixing is not a victimless crime; it harms customers in the form of artificially high prices. Consumers need to have faith that the prices they pay are fairly determined by the market, rather than the product of illegal collusion,” said U.S. Attorney Nicholas J. Ganjei for the Southern District of Texas. “The 11-year sentence Mr. Martinez received reflects the size and scope of his criminal operation, as well as his leadership role in organizing and facilitating the unlawful scheme.”  

“All of these defendants used their positions with the TFA to extort hardworking individuals who relied on these services to support their families and livelihood,” said Assistant Director Jose A. Perez of the FBI Criminal Investigative Division. “The FBI is committed to dismantling criminal enterprises that prey on vulnerable communities, and today’s sentencing sends a clear message that those who abuse systems will be found, stopped and brought to justice.”

“This case underscores the serious threat posed by transnational criminal networks operating at our borders,” said Special Agent in Charge Craig Larrabee of Immigration and Customs Enforcement Homeland Security Investigations (HSI) San Antonio. “Carlos Martinez and his co-conspirators orchestrated a violent scheme that extorted small businesses, fixed prices, and laundered millions of dollars — all while threatening the safety and integrity of lawful commerce. HSI will continue to aggressively pursue those who exploit legitimate industries through corruption and intimidation, and we remain steadfast in our mission to protect our communities and our economy.”

Individuals in the industry who were not part of the conspiracy were forced to join and pay into The Pool or face financial and violent consequences. Martinez and other members enforced the rules by monitoring whether forwarding agencies were charging the agreed-upon prices and whether the forwarder was making payments to The Pool.  

Martinez and some of his co-defendants also conspired to force forwarding agencies to pay other extortion fees, including a “piso” for every transaction processed as well as a “fine” for operating in the market outside of Pool rules. Martinez and his co-defendants intimidated, coerced, and used threats and acts of violence in furtherance of the antitrust and extortion conspiracies.

Martinez was responsible for collecting at least $9.5M in extortion payments. Cash obtained from the extortions was laundered through bank accounts controlled by Martinez and his family, with the cash deposits disguised to hide the nature, source, ownership, and control of the dirty money.

Martinez is the son-in-law of the former leader of the Gulf Cartel in Mexico, a violent criminal syndicate that operates at the U.S.-Mexico border and elsewhere. Martinez took control of  Los Indios Bridge and employed individuals who worked to track TFA transactions to calculate the piso owed by each forwarding agency. Pool and piso payments were made in cash to the individuals working for Martinez. Martinez ordered disciplinary actions against those operating in the transmigrante market without permission, those who violated Pool rules, those who did not charge the fixed prices, and those who did not pay the piso. Disciplinary actions could include clients not being allowed to cross Los Indios Bridge, cars being stolen, or more serious repercussions such as kidnappings, beatings, firebombings, shootings, and murder.

Carlos Martinez pleaded guilty in February  to conspiracy to illegally fix prices and allocate the market for TFA services, conspiracy to monopolize the transmigrante market, conspiracy to interfere with commerce by extortion, interference with commerce by extortion, and money laundering conspiracy. The government will also seek forfeiture of at least one house, luxury vehicles, a boat, and expensive watches.

Prior to Martinez’s sentencing, his co-defendants were sentenced as follows:

Carlos Yzaguirre, 66, of McAllen, Texas, was sentenced to two years in prison, after pleading guilty to conspiracy to interfere with commerce by extortion.

Sandra Guerra Medina, 70, of Rancho Viejo, Texas, was sentenced to eight months of home detention, after pleading guilty to conspiracy to illegally fix prices and allocate the market for TFA services and conspiracy to monopolize the transmigrante market.

Juan Hector Ramirez Avila, 59, a citizen of Mexico, was sentenced to time served, after pleading guilty to one count of structuring a financial transaction to evade reporting requirements.

Jose Tapia, Mireya Miranda, Pedro Calvillo and Roberto Garcia Villarreal pleaded guilty and are awaiting sentencing. Three other defendants, Rigoberto Brown, Miguel Hipolito Caballero Aupart, and Diego Ceballos-Soto, were also charged in the superseding indictment and remain fugitives.

The Court will determine the final restitution amount owed to victims of the conspiracies at a hearing set for Sept. 3, 2025. 

Immigration and Customs Enforcement Homeland Security Investigations and the FBI investigated the case.

Trial Attorney Christina Taylor of the Criminal Division’s Violent Crime and Racketeering Section; Senior Litigation Attorney John Davis and Trial Attorneys Brittany E. McClure, Anne Veldhuis, and Michael G. Lepage of the of the Antitrust Division; and Assistant U.S. Attorney Alexander L. Alum for the Southern District of Texas prosecuted the case.
