Since his highly publicized escape from a maximum-security Mexican prison in July, it has been assumed that notorious drug lord Joaquin “El Chapo” Guzmán Loera has once again taken the reigns of the powerful Sinaloa cartel. By his side for years has been Ismael “El Mayo” Zambada Garcia, who has so far escaped arrest. However, both drug lords are estimated to be in their early sixties, which means successors must be designated and groomed. The question is, will any of El Mayo’s four sons—known as “Los Mayitos”—fit this bill?
