About Mario Ramírez Treviño
- Mario Armando Ramírez Treviño (born 5 March 1962), commonly referred to by his aliases El Pelón and/or X-20, is a Mexican suspected drug lord and former leader of the Gulf Cartel, a drug trafficking organization. In the early 2000s, Ramírez Treviño was a close associate of Jaime González Durán (El Hummer), a founder and top leader of Los Zetas drug cartel.
- In 2008, González Durán was arrested and sentenced to 35 years in prison; by 2010, Los Zetas, who were working as the armed wing of the Gulf Cartel, separated from the organization to operate independently.
- Both criminal organizations went to war with each other, but Ramírez Treviño remained in the Gulf Cartel.
- Under the tutelage of Samuel Flores Borrego (El Metro 3), he worked as the second-in-command for the criminal organization in Reynosa, Tamaulipas.
- In an apparent power struggle within the Gulf Cartel, however, El Metro 3 was killed, and he became the regional kingpin in September 2011. With the death of El Metro 3, several groups within the Gulf Cartel went to war with each other, but Ramírez Treviño remained loyal to his faction, Los Metros.
- In late 2012, the Gulf Cartel leaders Mario Cárdenas Guillén and Jorge Eduardo Costilla Sánchez were arrested by the Mexican Armed Forces, forcing him to take the lead of the criminal organization.
- To keep the Gulf Cartel under his control and in a single command structure, Ramírez Treviño resorted to kill El Metro 4, Miguel "El Gringo" Villarreal, and other cartel leaders who stood in his way.
- He was arrested by the Mexican Army and Navy on 17 August 2013 in Reynosa.
