National media outlets such as Reforma and El Universal, which have accessed the document, reveal that the death certificate of Nemesio Oseguera Cervantes, alias 'El Mencho', identifies him as the leader of the Jalisco New Generation Cartel (CJNG), and states that his death was a direct result of multiple wounds caused by firearm projectiles. They report that according to the certificate issued by the Civil Registry of Mexico City, Oseguera Cervantes died on Sunday, February 22, 2026, at 10:30, while being transferred from Tapalpa, Jalisco, to Mexico City, within the context of a federal operation implemented for his capture. The document lists the cause of death as: 'Set of penetrating and perforating thoracic, abdominal, and lower limb trauma, secondary to injuries caused by projectiles fired from a firearm,' a description that corresponds to gunshot wounds to the chest, abdomen, and legs. The death certificate, issued by the Civil Registry of Mexico City on Saturday, was handed over to the family along with Oseguera's remains. He was identified by Mexican and U.S. authorities as the leader of the Jalisco New Generation Cartel (CJNG), an organization declared a terrorist group by the government of U.S. President Donald Trump. The registry lists the burial as the final disposition of the body. In a statement, the Attorney General's Office (FGR) reported on Saturday that after exhausting the necessary protocol procedures, the body had been handed over to his family. It added that genetic tests were performed to confirm that 'there were indeed blood ties between the person who requested the body and the deceased.' Nemesio Oseguera Cervantes, known as 'El Mencho' and also as 'El Señor de los Gallos,' was born on July 17, 1966, in the state of Michoacán de Ocampo, specifically in the community of Naranjo de Chila, municipality of Aguililla, in the Tierra Caliente region. According to official data, he was living in a common-law marriage.
