Leaders of Los Zetas, a Violent Mexican Drug Cartel, Arraigned on Drug Trafficking, Firearm, and Money Laundering Charges

Mexican nationals and former leaders of the Los Zetas cartel were arraigned today in Washington, D.C., on charges of engaging in a continuing criminal enterprise that involved multiple murder conspiracies, conspiring to manufacture and distribute large quantities of cocaine and marijuana destined for the United States, using firearms — including a machinegun — during and in relation to drug trafficking crimes, and conspiring to launder monetary instruments.

According to court documents, Miguel Trevino Morales, also known as Z-40, Zeta40, and 40, age 52, and Omar Trevino Morales, also known as 42 and Z-42, age 48, ascended to the highest level of leadership in Los Zetas, a violent cartel comprised of former Mexican military officers that began as an armed militaristic wing of the Gulf Cartel. Miguel Trevino Morales allegedly took over leadership of Los Zetas in October 2012 until his arrest by Mexican authorities in 2013, at which point, his brother, Omar Trevino Morales, allegedly assumed primary leadership of the cartel until his arrest by Mexican authorities in 2015. After their arrests, the defendants allegedly renamed Los Zetas to Cartel del Noreste (CDN) and continued to control the cartel while incarcerated in Mexico. Through the date of the fifth superseding indictment, CDN allegedly continued Los Zetas’ criminal drug trafficking activities and acts of violence including murders, assaults, kidnappings, assassinations, and acts of torture. On Feb. 20, 2025, the U.S. Department of State designated CDN as a foreign terrorist organization.

“The Criminal Division is dedicated to achieving the Attorney General’s goal of the Total Elimination of Cartels,” said Supervisory Official Matthew R. Galeotti, head of the Justice Department’s Criminal Division. “As alleged, former Zetas cartel leaders Z-40 and Z-42 engaged in conspiracies to kill members of the Mexican government, Mexican citizens, members of rival cartels, members of the Guatemalan government, and Guatemalan drug traffickers. We will aggressively pursue and bring to justice in the United States violent transnational criminals and leaders of cartels and hold them accountable for the death and violence they have committed here and abroad and for the large amounts of dangerous drugs that devastate our communities.”

“As alleged, the defendants represent some of the world’s most vicious cartel leaders, who oversaw Los Zetas’ reign of terror with grotesque impunity and ruthlessness, and a sheer disregard for anything beyond their wealth, power, and control,” said Acting Special Agent in Charge Michael Alfonso of ICE Homeland Security Investigations New York. “I commend ICE Homeland Security Investigations’ El Dorado Task Force for consistently proving itself as a formidable opponent against cartels intent on causing harm. We will use whatever means necessary to protect the safety and security of Americans from threats both here and abroad.”

The defendants are charged with one count each of continuing a criminal enterprise, conspiracy to distribute five kilograms or more of cocaine and 1,000 kilograms or more of marijuana for importation into the United States, use of a firearm in relation to drug trafficking crimes, and international money laundering conspiracy. As part of the continuing criminal enterprise count, the defendants are alleged to have engaged in conspiracies to kill members of the Mexican government, Mexican citizens, members of rival cartels, members of the Guatemalan government, and Guatemalan drug traffickers. Because the defendants are charged with engaging in a continuing criminal enterprise, they face a maximum penalty of death or life imprisonment.    

The defendants were subject to longstanding U.S. extradition requests, that were not honored during the prior Administration, but the Mexican government elected to transfer to the current U.S. government in response to the Justice Department’s efforts pursuant to President Trump’s and the Attorney General’s leadership against Mexican drug cartels. On Feb. 27, the defendants were transferred by Mexican authorities to the United States.   

The Drug Enforcement Administration, ICE HSI, and the FBI are investigating the case.

Acting Deputy Chief Melanie Alsworth and Trial Attorneys Jayce Born and Kirk Handrich of the Criminal Division’s Narcotic and Dangerous Drug Section, Assistant U.S. Attorney Andrew Wang for the Eastern District of New York, and the U.S. Attorney’s Office for the Western District of Texas are prosecuting the case.

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 Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhoods (PSN).
