MEXICO CITY, Mexico – Mexican law enforcement officials confirmed Tuesday that security operatives have taken into custody a nephew of infamous incarcerated drug kingpin Joaquin “El Chapo” Guzmán, who faces extradition requests from U.S. authorities. The arrest was carried out in Sonora, a northern Mexican state that shares a long border with the United States.
Omar García Harfuch, Mexico’s top security official, announced the capture via the social platform X, confirming that the detainee is a close nephew of the former Sinaloa Cartel leader, who is currently serving a life sentence at a U.S. maximum security prison. García Harfuch also noted that the suspect has been actively wanted by U.S. law enforcement agencies on unspecified charges related to organized crime.
In line with Mexican privacy protocols for criminal suspects, official authorities only publicly identified the detainee by the initial “Isai N.” However, multiple independent Mexican media outlets have named the suspect as Isai Martínez Zepeda. Press representatives for the Mexican security secretariat told Agence France-Presse they could not immediately verify or comment on additional local media reporting that the suspect was first apprehended by authorities back in 2008 while in possession of a cache of high-caliber military-grade weapons. Officials also declined to answer questions about when the suspect was released from prior custody, leaving a gap in the public timeline of his criminal history.
The capture of the younger Guzmán associate comes amid a years-long coordinated crackdown on the remnants of the Sinaloa Cartel led by both Mexican and U.S. authorities. El Chapo, the cartel’s founding leader, was extradited to the U.S. in 2017 following two high-profile escapes from maximum security Mexican prisons. He was convicted on a range of federal charges including large-scale drug trafficking, organized crime conspiracy, and money laundering, and is currently held at the ADX Florence supermax prison in Colorado.
In recent years, multiple other close family members of El Chapo have also been taken into custody and extradited to the U.S. Two of El Chapo’s own sons, Ovidio Guzmán López and Joaquín Guzmán López, both key leaders in the cartel’s operations, are currently imprisoned in the U.S. facing similar narcotrafficking charges.
