U.S. Attorney Announces Fentanyl Importation And Firearms Charges Against Major Fentanyl Producer For The Chapitos

An Indictment has been unsealed charging IVAN VALERIO SAINZ SALAZAR, a/k/a “Mantecas,” with fentanyl importation and related weapons offenses in connection with his participation in a conspiracy to produce fentanyl for the Sinaloa Cartel and import it into the United States, according to United States Attorney for the Southern District of New York, Jay Clayton, and Administrator of the U.S. Drug Enforcement Administration (“DEA”), Terrance C. Cole. The Mexican government announced the arrest of Sainz Salazar and his associates in Badiraguato, Sinaloa on January 19, 2026. “As alleged, Sainz Salazar served as a major producer of the Sinaloa Cartel’s fentanyl shipments bound for the United States,” said U.S. Attorney Jay Clayton. “Fentanyl kills, and violent dealers in fentanyl must be taken off our streets. Today’s charges target a major producer behind the Chapitos’ supply chain and underscore the commitment of the women and men of our Office to holding traffickers at all levels of the production and distribution chain accountable.” “Fentanyl is the deadliest drug threat this nation has ever confronted, and today’s indictment makes that unmistakably clear,” said DEA Administrator Terrance Cole. “The Chapitos, a faction of the Sinaloa Cartel, a foreign terrorist organization - ran an enterprise protected by armed sicarios and military-grade weapons, producing millions of counterfeit pills that have killed many people, and leaving devastation in their wake. This is not just alleged drug trafficking. Fentanyl is a weapon used to destroy lives. The DEA is dismantling these networks from the top down, and we will not relent until the laboratories are shut, the traffickers are behind bars, and these cartel organizations are destroyed piece by piece.” According to the allegations contained in the Indictment:1 The Sinaloa Cartel (the “Cartel”) is one of the most powerful drug cartels in Mexico and is largely responsible for the manufacturing and importing of fentanyl for distribution in the United States. Fentanyl is a dangerous synthetic opioid that is more than 50 times more potent than heroin. Fentanyl represents the single deadliest drug threat that the United States has ever encountered—it has ruined lives, devastated communities, and killed Americans at an unprecedented rate. The sons of the Cartel’s notorious former leader, “El Chapo,” who are themselves collectively known as the “Chapitos,” have variously and at times led the most powerful faction of the Cartel. To protect and further their fentanyl trafficking operation, the Chapitos and their confederates have relied on armed enforcers, known as sicarios, who commit acts of violence to protect the Chapitos’ operation and its leaders, territory, labs, trafficking routes, and money, and regularly use military-grade weapons smuggled from the United States, including machine guns, to perpetrate violence, including murder, torture, and kidnapping. From at least in or about 2022, up to and including in or about 2025, SAINZ SALAZAR served as a key fentanyl producer for the Chapitos. Among other things, SAINZ SALAZAR worked with others to produce millions of fentanyl pills on behalf of the Chapitos, participated in meetings to arrange fentanyl transactions, carried firearms and relied on armed security personnel at those meetings, and reported to high-ranking lieutenants of the Chapitos who themselves relied on sicarios armed with AK-47s and FN Minimis for the protection and promotion of their fentanyl operations. In or about 2023, the Chapitos consolidated fentanyl production at labs operated by SAINZ SALAZAR and his associates and issued orders authorizing only SAINZ SALAZAR and his associates to produce and distribute fentanyl in territories controlled by the Chapitos. SAINZ SALAZAR, 40, a Mexican national, is charged with conspiring to import fentanyl into the United States, which carries a mandatory minimum sentence of 10 years in prison and a maximum sentence of life in prison; conspiring to distribute and possess with intent to distribute fentanyl in the United States, which carries a mandatory minimum sentence of 10 years in prison and a maximum sentence of life in prison; using, carrying, and possessing machine guns and destructive devices in connection with the fentanyl importation conspiracy, which carries a mandatory minimum sentence of 30 years in prison and a maximum sentence of life in prison; and conspiring to use, carry, and possess machine guns and destructive devices in connection with the fentanyl importation conspiracy, which carries a maximum sentence of life in prison.
