An indictment unsealed in the Western District of Texas is the first in the nation to charge a Mexican national with providing material support to a designated foreign terrorist organization based on her involvement with the Cartel de Jalisco Nueva Generación (CJNG), including providing the cartel with grenades and engaging in alien smuggling, firearms trafficking, bulk cash smuggling, and narcotics trafficking on its behalf.
“Cartels like CJNG are terrorist groups that wreak havoc in American communities and are responsible for countless lives lost in the United States, Mexico, and elsewhere.” said Attorney General Pamela Bondi. “This announcement demonstrates the Justice Department’s unwavering commitment to securing our borders and protecting Americans through effective prosecution.”
According to court documents, Maria Del Rosario Navarro-Sanchez, 39, of Mexico, conspired with others to provide and did attempt to provide grenades to CJNG, a designated foreign terrorist organization. Additionally, Navarro-Sanchez, is charged with conspiracy to smuggle and transport aliens in the United States, straw purchasing and trafficking in firearms, bulk cash smuggling conspiracy, and conspiracy to possess a controlled substance with intent to distribute. Co-defendant Luis Carlos Davalos-Lopez, 27, of Mexico, is charged with conspiracy to smuggle illegal aliens into and transport aliens in the United States, straw purchasing and firearms trafficking. Co-defendant Gustavo Castro-Medina, 28, of Mexico, is charged with straw purchasing and firearms trafficking, conspiracy to possess a controlled substance with intent to distribute, and possession of a controlled substance with intent to distribute.
On Feb. 20, the U.S. Department of State announced the designation of eight international cartels, including CJNG, as Foreign Terrorist Organizations (FTOs) and specially designated global terrorists. This designation makes available much stronger criminal charges in the fight to secure our nation’s borders. CJNG is a transnational criminal organization that controls a significant portion of the narcotics trafficking trade and has a presence in nearly every part of Mexico and dozens of other countries, including the United States. In addition to trafficking fentanyl, CJNG engages in money laundering, bribery, extortion of migrants, taxing of migrant smugglers, and other criminal activities, including acts of violence and intimidation. According to the State Department, CJNG has conducted attacks on Mexican military and police with military grade weaponry, the use of drones to drop explosives on Mexican law enforcement, and assassinations or attempted assassinations of Mexican officials.
On Jan. 20, President Trump directed the Justice Department and other agencies to pursue total elimination of cartels and transnational criminal organizations because they pose extremely serious threats to the United States, including by jeopardizing a stable and secure border. These and other criminal organizations commit brutal and intolerable violent crimes related to narcotics and firearms trafficking, money laundering, extortion, and other criminal acts. They also are responsible for huge flows of illegal immigration into the United States. They organize and facilitate all manners of illicit travel and immigration into the United States through the southern and northern borders and rely on co-conspirators and organization members operating in various countries throughout North and South America. This situation is untenable and threatens our national security. The Department of Justice and its law enforcement partners are committed to protecting the United States against invasion, working urgently toward the goal of total elimination of cartels and transnational criminal organizations, aggressively enforcing our immigration laws, and maximizing the impact and effectiveness of all available law enforcement tools.
“We will never allow criminal gangs and cartels to terrorize American communities,” said Secretary of Homeland Security Kristi Noem. “The days of unchecked gang and cartel violence are over.”
“As alleged, the defendant engaged in multiple of the most insidious kinds of criminal activity: firearms trafficking, narcotics trafficking, human and bulk cash smuggling, and even providing grenades to CJNG,” said Matthew R. Galeotti, Head of the Justice Department’s Criminal Division. “Today’s announcement demonstrates the Criminal Division’s hard work and commitment to eliminate cartels and foreign terrorist organizations like CJNG."
“The slew of federal charges we have brought against Navarro-Sanchez sends a monumental message through the ranks of cartels like CJNG—now designated as a terrorist organization—along with those who support them in various capacities, that U.S. law enforcement is turning up the pressure to crack down on unlawful immigration practices and to dismantle the smuggling of illicit drugs and firearms,” said Acting U.S. Attorney Margaret Leachman for the Western District of Texas. “These crimes, all included as allegations in the indictment, do nothing but place human lives on both sides of the border in grave danger, while loading the pockets of criminals who profit off of them.”
“The arrest of Maria Del Rosario Navarro-Sanchez should send a clear message to people who wish to align themselves with terrorist groups that they will be sought out and held to the highest extent of the law,” said FBI Director Kash Patel. “I'm extremely proud of the dedicated men and women of the FBI and its law enforcement partners who work tirelessly every day to protect Americans and keep our communities safe.”
“The brutality and destruction inflicted by cartels and terrorist organizations is devastating communities across the United States and around the world,” said Bureau of Tobacco, Firearms and Explosives (ATF) Acting Director Dan Driscoll. “The capture and arrest of Maria Del Rosario Navarro-Sanchez demonstrates what international law enforcement cooperation can achieve when united against the threat posed by these violent networks. ATF and our partners will use every tool at our disposal to relentlessly hunt down, dismantle, and bring to justice every trafficker, every cartel operative, and every individual who dares to threaten the safety and sovereignty of our communities.”
“This case lays bare the true nature of the threat we face,” said Drug Enforcement Administration Acting Administrator Robert Murphy. “A cartel associate providing support to a designated foreign terrorist organization is not just a criminal threat—it is a national security threat. DEA will use every tool of law enforcement to dismantle CJNG and its network that floods our streets with poison, traffics in human lives, and wages violence against law and order. We are not just keeping our communities safe from dangerous, illegal drugs—we are fighting a national security crisis.”
“Supplying grenades to a designated terrorist organization—while trafficking firearms, narcotics, and human beings—is not just criminal; it’s a direct assault on the security of the United States,” said Acting U.S. Immigration and Customs Enforcement (ICE) Director Todd M. Lyons. “Sanchez acted as a key enabler of violence who empowered cartels and terrorist organizations. Her crimes extended beyond smuggling; she was involved in firearms trafficking, bulk cash smuggling conspiracy, and a conspiracy to distribute controlled substances. Her actions endangered countless lives and undermined our efforts to protect the nation’s borders and communities. Confronting this level of criminality demands more than resolve—it requires a unified, all-of-government response, and that’s exactly what we demonstrated today: a coordinated effort to identify, disrupt, and bring to justice those who profit from violence and human suffering.”

Since its establishment, Joint Task Force Alpha’s (JTFA) work has resulted in increased coordination and collaboration between both domestic and foreign law enforcement; precedent setting indictments, extraditions and prosecutions; more than 365 domestic and international arrests of leaders, organizers, and significant facilitators of these crimes; more than 334 U.S. convictions; more than 281 defendants sentenced, including significant jail sentences imposed; and substantial seizures and forfeitures of assets and contraband including millions of dollars in cash, real property, vehicles, firearms and ammunition, and drugs.
The FBI, ATF, DEA, and Homeland Security Investigations in El Paso, assisted by the U.S. Border Patrol, investigated the case. ATF Legal Attachés in Mexico City and the Mexico Attorney General’s Office also known as FiscalÃa General de la República (FGR) Firearms Trafficking Unit provided substantial assistance. The CBP’s National Targeting Center, and ICE HSI’s Human Smuggling Unit in Washington, D.C. also provided assistance with the investigation.
The case announced today is being prosecuted by Assistant U.S. Attorney Kyle Myers and JTFA Associate Director Ian Hanna of the Western District of Texas, and Trial Attorney Marie Zisa of the Criminal Division’s Human Rights and Special Prosecutions Section. The Justice Department’s Office of International Affairs and Judicial Attachés in Mexico provided substantial assistance. The Justice Department thanks its Mexican law enforcement partners, who arrested Navarro-Sanchez on May 4, during an enforcement operation.
This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Project Safe Neighborhood (PSN).
This case is also part of an Organized Crime Drug Enforcement Task Forces (OCDETF) Strike Force Initiative, which provides for the establishment of permanent multi-agency task force teams that work side-by-side in the same location. This co-located model enables agents from different agencies to collaborate on intelligence-driven, multi jurisdictional operations to disrupt and dismantle the most significant drug traffickers, money launderers, gangs, and transnational criminal organizations. The OCDETF El Paso / Las Cruces Strike Force is comprised of agents and officers from CBP, HSI, DEA, FBI, IRS Criminal Investigation, the U.S. Marshals Service, ATF, the El Paso County Sheriff's Office (EPSO), and the El Paso Police Department (EPPD).
The charges contained in an indictment are merely allegations. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
