The head of the Gulf Cartel has been indicted in Brownsville on various drug charges.

Jose Alfredo “El Contador” Cardenas-Martinez is currently in custody in Mexico pending litigation on the U.S.’s extradition request, the United States Attorney’s Office announced Thursday.

According to the charges, Cardenas-Martinez, 42, has been the head of the Gulf Cartel, or Cartel del Golfo, since 2015 following the arrest and later conviction of Jorge Eduardo Costilla-Sanchez aka “El Cos”.

If convicted, Cardenas-Martinez faces up to life in prison and a possible $10 million fine.
