Mexico’s government said the army netted Mario Armando Ramírez Treviño, a drug boss in Reynosa who had been vying to take over the cartel since the arrest of the Gulf’s top capo, Jorge Eduardo Costilla Sánchez, alias “El Coss,” last September. Some say he succeeded, while others say the cartel continues to be split into factions.
The US State Department is offering a reward of USD 5 million for his capture. Ramírez, who was born in 1962 according to the US government, is wanted on several federal drug violations.
Tamaulipas state government spokesman Rafael Luque said there was a major operation of the Mexican military about 1 p.m. local time Saturday with helicopters in the town of Rio Bravo. He could not confirm if there were deaths or injuries in the offensive.
The once-powerful Gulf Cartel still controls most of the cocaine and marijuana trafficking through the Matamoros corridor across the border from Brownsville, Texas, and has an international reach into Central America and beyond. But the cartel has been plagued by infighting since Costilla’s arrest, while also being under attack in its home territory by its former security arm, the Zetas.
In the Gulf succession fight, Ramírez and rival Michael Villarreal, known as “Gringo Mike,” have been at odds, according to US law enforcement, and the cartel divided into two major factions of those loyal to Costilla and those loyal to former boss Osiel Cárdenas Guillén, who was arrested in 2003 and extradited to the US in 2007, where he is serving a 25-year prison sentence.
The split is blamed for much of the violence in the border city of Reynosa across from McAllen, Texas, where there have been regular, public shootouts between Gulf factions and authorities in the last six months.
In recent years, the Mexican government has made major hits on the leadership of both the Gulf and Zetas, who were aligned until 2010. Their falling out also caused an unprecedented spike in violence in the border state of Tamaulipas.
In 2010, government forces killed Cardenas’ brother and successor, Antonio Ezequiel Cárdenas Guillén, then captured a third brother and leader, Mario Cárdenas Guillén, just days before Costilla.
Mexican authorities have said the Gulf Cartel divided after Antonio Ezequiel’s 2010 death into one group led by his brother Mario and the other by Costilla.
On July 15, in the first major arrest of a capo during Peña Nieto’s administration, authorities in northern Mexico captured Miguel Ángel Treviño Morales, alias “Z-40,” leader of the brutal Zetas cartel. Last October, Mexican marines killed Zeta leader and founder Heriberto Lazcano Lazcano, alias “El Lazca.”
Authorities are still waiting for the fallout from Treviño’s capture as lieutenants battle to take over the Zetas.
