Mexico says its Navy killed a cartel operator wanted by the United States in a gunfight in the northwestern state of Sinaloa on Monday, 26 October 2026. Security Secretary Omar García Harfuch, the federal minister in charge of national security, announced it on Wednesday, 28 October.
Harfuch named one of the two dead men as Jesús “Chuy” González Peñuelas, whom the United States wants as a fugitive and for whom the US State Department offers a reward of up to US$5 million. A joint statement by the Navy and the Security Secretariat says DNA and fingerprint tests must still establish the identity of both men.
The case matters to US readers because Washington says his network moved drugs including fentanyl into the United States, with distribution cells in six states, and has sanctioned him twice. Every statement about his role here is an allegation by the Mexican or US government, not a court finding.
In Plain English
Navy (SEMAR): Mexico’s naval force, which also carries out security operations on land. Security Secretariat (SSPC): the federal security ministry, led by Harfuch.
Cártel de Guasave: the criminal group from northern Sinaloa that Harfuch linked to the dead man. FGR: the federal Attorney General’s Office, which now holds the seized weapons and trucks.
What Happened
Navy personnel working on naval intelligence leads located vehicles carrying armed people, the joint statement says. Two men got out of a pickup truck, hid in brush and opened fire on the approaching naval personnel, who returned fire.
Both men died, and the site was preserved until prosecutors arrived, according to the statement. Federal forces seized four pickup trucks reported stolen, three long guns, three magazines and 46 cartridges for the FGR case file.
Harfuch wrote on X that the operation advanced the pacification of Sinaloa and that two people lost their lives, among them Chuy Peñuelas. He added that the US government had offered a US$5 million reward for him.
The statements announce no arrests. Relatives told prosecutors the dead could be two named men, but no name beyond Harfuch’s has been confirmed.
Who the Dead Man Is Said to Be
Harfuch called him one of the operators of the Cártel de Guasave, a group named after the city of Guasave in northern Sinaloa. Mexican authorities describe him as a second-level operator below its leader, Fausto Isidro Meza Flores, known as El Chapo Isidro.
The US State Department lists him as Jesus Gonzalez Penuelas, alias Chuy Gonzalez, born in 1969, and offers up to US$5 million for information leading to his arrest or conviction. The DEA, the US federal anti-drug agency, also lists him as a fugitive, and the reward dates from January 2024.
The Treasury Department says he heads an organisation in Sinaloa that has supplied methamphetamine and heroin to the United States since 2007, with distribution cells in six US states. It says he was indicted in Southern California in 2017 and in Colorado in 2018.
Treasury sanctioned him under a US drug-kingpin law on Wednesday, 12 May 2021, and again on Wednesday, 20 May 2026, as a cell leader of the Sinaloa Cartel. The State Department designated the Sinaloa Cartel a foreign terrorist organisation in a notice published on Thursday, 20 February 2025.
What Officials Say About Sinaloa
President Claudia Sheinbaum said at her morning news conference on Wednesday, 28 October, that homicides in Sinaloa have risen over the past two months and particularly in recent weeks. She told residents the government is there to protect them and will keep working.
She added that Harfuch was meeting Sinaloa’s governor that day, and the Navy statement says federal forces will keep their presence in the state. The Treasury Department said in May that turf wars between cartel factions had left more than 600 people dead in Sinaloa since September 2024.
Why It Matters to the United States
Treasury says the Sinaloa Cartel is responsible for a significant portion of the illicit fentanyl that kills tens of thousands of Americans each year. The killing therefore lands in the wider debate over relations between Mexico and the United States.
Mexico presents the operation as the result of its own naval intelligence work. The statements name no US agency as taking part.
What It Means for You
The State Department’s Mexico travel advisory lists Sinaloa under “Do Not Travel” because of crime and lets US government employees visit only Mazatlán, Los Mochis and Topolobampo, by air or sea. A guide to safety in Mexico by state shows how other states compare.
Anyone with business or family in Sinaloa should expect federal forces to stay visible. Travellers should check the current advisory before any trip, and the latest security news is collected in Mexico coverage.
What Is Not Known
The identity of both dead men is not formally confirmed, because the joint statement says DNA and fingerprint tests are still needed. No US statement on the death had been found by midday on Wednesday, 28 October.
The exact place is also open, since the joint statement names only the locality of Alfredo V. Bonfil in Sinaloa state, while an earlier report on the chase had placed it near Guasave on local accounts. It is also unknown whether the killing triggers retaliation, or whether the US reward can be paid for a man who has died.
