MEXICO CITY (July 16, 2013)—Trevino Morales, the head of Mexico's notorious Zetas drug cartel has been arrested in Nuevo Laredo across the border from Mexico.
Mexican Marines captured Morales Monday.
The capture of Morales, known as "Z-40," represented the biggest victory in President Enrique Pena Nieto's efforts against cartels, according to Mexican media.
Morales took control of the Zetas after the death of group founder Heriberto Lazcano in October 2012.
The U.S. State Department had offered a $5 million reward for him.
Experts, however, say his arrest is unlikely to diminish violence in border states where the cartel dominates through terror.
