Former Gulf Cartel Boss Mario Cardenas Guillen Approved for US Extradition

Mario Cárdenas Guillén

Mexico's Attorney General's Office (FGR) announced yesterday that former Gulf Cartel boss Mario Cárdenas Guillén, alias "El M-1" and/or "El Gordo", had been approved for U.S. extradition. Mario is the brother of Osiel Cárdenas Guillén, who was once the top leader of the Gulf Cartel and its former paramilitary group, Los Zetas.

Mario issued a motion arguing that U.S. Embassy employees Dorothy Krebs Sarro and William H. Duncan were not eligible to request an extradition request on behalf of the U.S. government. However, a federal judge in the State of Mexico said that the request was valid and approved his extradition.

Mario is currently imprisoned at the Federal Social Readaptation Center No. 1 ("Altiplano"), a maximum-security prison in the State of Mexico. He is wanted in the U.S. state of Texas for drug trafficking.

Earlier this year, Borderland Beat reported that Mario had been successful at halting his extradition to the U.S. His attorneys were able to convince a federal judge to re-review the prerequisites required for his transfer and that the prosecution had violated several articles of the Extradition Treaty between the U.S. and Mexico.


Mario was born in Matamoros, Tamaulipas, the historic home base of the Gulf Cartel, in 1964. He was imprisoned at a penitentiary in Matamoros in 1995 for drug trafficking and organized crime involvement.

While in prison, Mario was also known for holding large parties, inviting prostitutes, organized gambling rings for horse races and cockfights, and having all sort of commodities. He was also suspected of coordinating drug trafficking activities for the Gulf Cartel. Federal authorities then transferred him to the Federal Social Readaptation Center No. 2 ("Puente Grande"), a maximum-security prison in Jalisco.

He was released from prison in 2007 and resumed his organized crime activities. He rose through the ranks of the Gulf Cartel after the November 2010 death of his brother Antonio Ezequiel Cárdenas Guillén ("Tony Tormenta").

Mario was part of a faction known as Grupo M/Los Marinos, which was reportedly made up of former marines and was based in Matamoros. His code name was "M-1", but it is often confused with the code names from another Gulf Cartel faction, Los Metros. Cartel member Lorenzo Cuéllar Botello from Los Metros also had the code name "M-1". In September 2012, Mario was arrested by the Mexican Navy in Altamira, Tamaulipas.

Mario Cardenas Guillen - U.... by MX


  1. He's FUCKED BIG TIME upon 🇺🇸 soil.

  2. What's AMLO's extradition count in 2 years? We need a number to quiet down all of his doubters.

  3. Who gave him up? Possibly Oziel ?

    1. The rumor I've heard is that El Coss gave up Tony Tormenta, so I assume he also gave up ol' chubster Mario.

    2. No. Rumor was that el coss gave him up but theres no proof. Why wld oziel give his own brother up for. Thats just stupid.

    3. Hay otro rumor donde se dice que Costilla vio la debilidad de los Cardenas y la aprovecho, ahí el fuerte era Tormenta murio en 2010 a meses comenzar la Guerra y pues el resto de Cardenas se entregaron o se alinearon, Coss solo duro 2 años pues la tuvo dificil con la muerte del Metro 3, al final se decia que Coss y Lazca habian tenido un acercamiento y eso provoco que una parte de su personal se alejara ejemplo X20.

      Osiel no tiene oportunidad de regresar, su Yerno se quedo son su lugar, sus sobrinos jamás le daran algo que a ellos les ha costado sangre y fuego, lo respetarán por ser su Tio pero jamás como lider.

      Osiel debe aprovechar quedarse en USA porque tanto en Matamoros como en otros Municipios de la Frontera Tamaulipeca hay muchas personas que le quieren cobrar cuentas.

    4. That rumor also started the war between factions from reynosa and matamoros

  4. DON'T WORRY. They won't stick you within shouting distance of El Chapo.

  5. Stupiro gave himself up when he took eagerly the position of "Replacement of Tony Tormentos", nobody was asking him anout his sexual problems

    1. The mexican military, they needed reliable leadership in the CDG, and they got it.

    2. Mexican Marines
      Some say a women gave up his location.
      Others say el coss told the military of his whereabouts

  7. Animo Sicarios!

    El M-1 was the code of a legendary CDS Sicario, his name was José Manuel Torres Félix.

    He was highly trained in Kali Eskrima which explains why he was so effective with his knife.
    This is a reserved code and cannot be used by anyone else .
