BROWNSVILLE, Texas — The man who once had full command of the Gulf Cartel during its heyday pleaded guilty to drug conspiracy and charges of assaulting a federal officer.
Jorge “El Coss” Costilla Sanchez went before U.S. Magistrate Judge Ronald Morgan and entered a guilty plea to one drug conspiracy charge and two separate counts of assault on a federal officer.
From 2003 until his arrest in 2012, Costilla controlled the criminal organization known as the Gulf Cartel (CDG). According to the U.S. District Attorney’s Office, since the 1990’s the Gulf Cartel has been Mexico’s leading drug trafficking and money laundering organization in the northern part of Tamaulipas.
Costilla inherited the command of the Gulf Cartel from its previous leader, Osiel Cardenas Guillen, who is currently serving a 25-year sentence in a U.S. prison. Cardenas was arrested in 2003 and extradited to Texas in 2007.
According to prosecutors, Costilla-Sanchez was responsible for making strategic decisions and trying to manage the various factions of the Gulf Cartel, including Los Zetas who eventually broke away. Beginning in 1998, Costilla helped the Gulf Cartel move tons of cocaine and marijuana into the country through the international bridges in Hidalgo and Cameron County, as well as through the waters of the Rio Grande and through the Gulf of Mexico into the Texas coast.
