Mexico: Will Los Zetas Unravel Without Their Leader?

The arrest of Los Zetas leader Miguel "Z-40" Trevino Morales marks the most significant capture involving a Mexican organized crime leader since 2008. On July 15, Stratfor sources confirmed Mexican and U.S. media reports saying that Trevino was arrested in Nuevo Laredo, Tamaulipas state, and that he was being transferred to Mexico City. Reports indicate that he was arrested late July 14, though that has not been confirmed. At least one source claims Trevino's nephew was also arrested. 

Trevino became the leader of Los Zetas, one of Mexico's most prolific and most territorial organized crime groups, sometime in 2012 shortly before then-leader Heriberto "El Lazca" Lazcano Lazcano was killed by the Mexican navy. Trevino's arrest could change Mexico's criminal landscape substantially if Los Zetas begin to unravel in his absence.
