What We Know: He was the brother of Osiel "the Friend Killer" Cárdenas, who led the Gulf cartel until his arrest in 2003. He now runs the organization along with Jorge Eduardo Costilla.

On November 5, 2010, the Mexican government announced that Cardenas had died that day in a shootout with security forces in the border city of Matamoros. The death came after hundreds of soldiers moved into Matamoros, across from Brownsville, Texas, and launched a full-scale assault on Cardenas' cartel.
