Federal prosecutors say Irving Froilán León Alvarado worked inside Los Chapitos’ security structure for years, but narcocorridos had already publicly linked him to Ovidio Guzmán and El Nini long before his 2026 arrest.
Two narcocorridos released in 2023 and 2025 portrayed “El 18” as part of the Los Chapitos organization. Before the FBI built its case file, two narcocorridos had already done much of the work: name, nickname, hometown, boss, and weapons.
Irving Froilán León Alvarado, alias “El 18,” currently detained in the United States, was portrayed in lyrics and music as a personal bodyguard for Ovidio Guzmán López. The first song appeared in 2023, when “El Ratón” was still operating in Sinaloa, and the second in 2025, during the ongoing war between Los Chapitos and La Mayiza.
Federal authorities reached him through a different route: an ex-girlfriend who cooperated, a cellphone filled with photos, and a chain of Facebook messages linking him to the cartel since 2015, according to journalist Ángel Hernández.
U.S. federal authorities arrested him in January 2026 on a minor marijuana possession charge. But once his information entered Department of Justice databases, a much larger case emerged: methamphetamine production and trafficking, along with firearms possession charges.
On June 9, 2023, the label Del Records, the same label later linked to the CJNG, released the song “Clave 18,” performed by Panchito Arredondo with Los Novillos de la Sierra.
The song opens with an operational image: armored trucks moving in convoy, carrying rocket launchers and heavy weapons. The lyrics explain that the scene signals El Ratón is nearby, which is why his men wear tactical vests tightened and ready.
The second section describes the narrator in first person. He mentions grenades and an RPG launcher prepared for use, along with an engraved pistol strapped to his leg. He presents himself as armed and ready for war while protecting one of “General” Guzmán Loera’s sons.
Another verse references “a random Thursday in Culiacán,” a direct allusion to the Culiacanazo on October 17, 2019, when federal forces captured Ovidio Guzmán but released him hours later after cartel blockades and violence overwhelmed the city.
Then comes the identification.
The narrator says he protects Ovidio Guzmán day and night and claims he earned that role through actions that gained the cartel leader’s trust. In the final verse, he identifies himself openly: originally from Agua Caliente, member of the Sinaloa Cartel, assigned by El Nini to guard the boss.
“24/7 you’ll see me alert,” the verse concludes.
The second song arrived under radically different circumstances.
“Irvin El 18,” by the group Decisión Efectiva, was released in 2025, after Los Chapitos had already spent months in open war against the faction aligned with Ismael “El Mayo” Zambada. That conflict exploded on September 9, 2024.
The tone is drastically different from the 2023 corrido.
There is no longer a convoy escorting El Ratón through Sinaloa. Instead, the narrator speaks about controlling sectors, operating with a team at his side, and carrying heavy weapons. He reaffirms both his identity, Irving “El 18,” and his loyalty within the cartel.
“The Chapos know I always answer for them,” one lyric states.
The song also carries the absence of Ovidio Guzmán. One verse laments what happened in Jesús María, the Culiacán neighborhood where El Ratón was arrested in January 2023, describing it as a mistake that made too much noise and where “the Navy came down.”
Another lyric says he struggles to “get his head straight” and that the event shattered him.
In that context, the song’s declaration of loyalty takes on greater weight:
“My line is one thousand percent Guzmán. El Nini left us the school here.”
El Nini, the former head of security for Los Chapitos who has been imprisoned and extradited since 2023, remains a symbol of authority within the organization even from prison.
The corrido also describes caravans still patrolling both cities and rural areas, along with a narrator who says he arrives heavily armed and equipped.
It closes with a line echoing the first song, now carrying even more weight:
“I’m Irving. I’m from the cartel. Chapo’s cartel.”
What is known about his arrest?
What the FBI spent months building reached federal court through the smallest possible doorway.
Immigration and Customs Enforcement (ICE) detained León Alvarado in January 2026 for marijuana possession, a minor offense. There was no large operation and no visible long-term surveillance beforehand. It was a routine arrest that escalated the moment agents entered his name into federal databases.
The Department of Justice immediately requested custody.
The case waiting for him was far from minor: methamphetamine production and trafficking, along with firearms charges. He appeared before a federal judge on January 16, 2026.
The maximum sentence he faces is life in prison.
It was not his first arrest in the United States.
He had previously been arrested in the U.S. in 2017 and deported in 2018. According to court records, his return to Mexico marked the beginning of his rise within the cartel. He allegedly started as a “halcón,” or lookout, monitoring and reporting movements, before climbing the ranks until Ovidio Guzmán integrated him into his personal security team.
After El Ratón’s arrest in January 2023, León Alvarado was reassigned as a bodyguard for Guzmán’s immediate family.
Authorities say he remained active in that role at least until July 19, 2024, the date of a photograph the FBI recovered from his ex-girlfriend’s cellphone. In the image, he allegedly appears carrying a Barrett rifle while dressed in full tactical gear.
The case was sealed by the court after his initial appearance before the judge. There is currently no public confirmation on whether León Alvarado is negotiating a plea agreement or preparing for trial.
