Miguel Treviño Morales
Miguel Ángel Treviño Morales (a.k.a. Z-40) is a Mexican drug lord and top leader of a criminal organization known as Los Zetas. Unlike the original founders of Los Zetas, Treviño Morales has no military experience, and instead worked for a local gang as a teenager before being recruited in the 1990s. He is known by his adversaries and law enforcement officials for his violent reputation and as a "brutal assassin" responsible for being behind much of the violence in Mexico.
Treviño Morales is an important figure in the Zetas, who acted as regional boss of Nuevo Laredo, Tamaulipas and as the second-in-command of the organization. Since early 2010, Treviño Morales began to have a bigger role in Los Zetas. Los Zetas are responsible for the smuggling of multi-ton quantities of cocaine, marijuana and heroin into the United States from Mexico annually.
He is currently on Mexico's most-wanted list, with a $30 million MXN ($2.3 million USD) reward offered to information leading to his arrest. The United States Department of State is offering up to $5 million USD ($62.4 million MXN) for his arrest and conviction.
