Gulf Cartel
Without a clear successor of Costilla Sánchez, his faction – the Metros – could come to an end, although it is still likely that there are other old-crime boses of lesser importance still trying to keep the Gulf Cartel standing. With the recent arrest of a Gulf Cartel representative in Colombia, the drug business could be disrupted even further. One clear benefactor of the fall of the Gulf Cartel is its rival group, Los Zetas. It is also possible that the several within the Gulf Cartel may decide to join the Sinaloa Cartel or Los Zetas, although the latter seems unlikely given the bitter sentiment both groups have planted.
