Mario Ramirez Trevino

Mario Armando Ramírez Treviño
, alias El X-20 and Pelón, is a Mexican drug lord and high-ranking lieutenant in The Gulf Cartel. He reportedly became the regional boss of the cartel in Reynosa, Tamaulipas after the death of the drug lord Samuel Flores Borrego alias El Metro 3 in 2 September 2011. Prior to his death, Ramírez Treviño was a frequent contact and close associate of Jaime González Durán (El Hummer).

After the September 2012 arrest of Jorge Eduardo Costilla Sánchez, the supreme leader of the Gulf Cartel, unconfirmed reports indicated that Ramírez Treviño, the right-hand man of the fallen Flores Borrego, may possibly be the next in line to take the lead of the cartel.

Death of Flores BorregoEdit

On 2 September 2011, the Mexican authorities discovered the bullet-ridden corpse of Samuel Flores Borrego inside a Ford Lobo truck on the Mexican Federal Highway 40, which connects Reynosa with Monterrey and is directly across the U.S-border with McAllen, Texas. His body was found along with the corpse of a high-ranking policeman named Eloy Lerma García from Gustavo Díaz Ordaz, Tamaulipas. Initial reports from the Mexican government indicated that Flores Borrego had apparently been killed by "members of his own cartel." The two men were first stripped to their under wears, severely beaten, tortured and then shot dead; their corpses were then left on the bed of the Ford Lobo along with a message against the cartel faction Flores Borrego commanded – a group known as Los Metros. A jeweled pistol was found nearside his body too. The Mexican authorities never confirmed it, but the execution-style killings bore the signs of an internal adjustment within the cartel, and sources outside of law enforcement confirmed that Juan Mejía González (El R-1) and Rafael Cárdenas Vela (El Junior) were responsible for Flores Borrego's assassination.

Within a few hours, however, the Gulf cartel replaced Flores Borrego with Ramírez Treviño (known for his aliases X-20 and Pelón) as the new plaza boss in Reynosa. Ramírez Treviño was a frequent contact of Flores Borrego and a former close associate of Jaime González Durán (El Hummer).

Metros and Rojos infightingEdit


In the late 1990s, Osiel Cárdenas Guillén, the former leader of the Gulf cartel, had other similar groups besides The Los Zetas Organization established in several cities in Tamaulipas. Each of these groups were identified by their radio codes: the Rojos were based in Reynosa; the Metros were headquartered in Matamoros; and the Lobos were established in Laredo. The infighting between the Metros and the Rojos of the Gulf cartel began in 2010, when Juan Mejía González, nicknamed El R-1, was overlooked as the candidate of the regional boss of Reynosa and was sent to the "Frontera Chica," an area that emcompasses Miguel Alemán, Camargo and Ciudad Mier – directly across the U.S-Mexico border from Starr County, Texas. The area that Mejía González wanted was given to Flores Borrego, suggesting that the Metros were above the Rojos.

Unconfirmed information released by The Monitor indicated that two leaders of the Rojos, Mejía González and Rafael Cárdenas Vela, teamed up to kill Flores Borrego. Cárdenas Vela had held a grudge on Flores Borrego and the Metros because he believed that they had led the Mexican military to track down and kill his uncle Antonio Cárdenas Guillen (Tony Tormenta) in 5 November 2010. Other sources indicate that the infighting could have been caused by the suspicions that the Rojos were "too soft" on the Gulf cartel's bitter enemy, Los Zetas. When the Gulf cartel and Los Zetas splited in early 2010, some members of the Rojos stayed with the Gulf cartel, while others decided to leave and join the forces of Los Zetas.

InSight Crime explains that the fundamental disagreement between the Rojos and the Metros was over leadership. Those who were more loyal to the Cárdenas family stayed with the Rojos, while those loyal to Jorge Eduardo Costilla Sánchez, like Flores Borrego, defended the Metros.

Originally, the Gulf cartel was running smoothly, but the infighting between the two factions in the Gulf cartel triggered when Flores Borrego was killed on 2 September 2011. When the Rojos turned on the Metros, the largest faction in the Gulf cartel, firefights broke throughout Tamaulipas and drug loads were stolen among each other, but the Metros managed to retained control of the major cities that stretched from Matamoros to Miguel Alemán, Tamaulipas.
