Mexico has captured the head of the notoriously vicious Zetas drug cartel. Miguel Angel Trevino Morales, known as “Z-40,” was caught in Nuevo Laredo by Mexican Marines. He’s reputed to be exceptionally dangerous and violent—he's known to burn his enemies alive in 55-gallon drums. The Zetas have spread terror through Mexico in the brutal drug war as they’ve made their name displaying bodies of their murdered victims throughout the country. Trevino Morales’s capture is thought to be the first major blow against organized crime by President Enrique Peña Nieto, whose campaign promised to drive down crime figures.
