48. Joaquín 'El Chapo' Guzmán

Title: Leader, Sinaloa Cartel

Country: Mexico

Age: 60

Mexican drug lord Joaquín "El Chapo" Guzmán is perhaps the wealthiest and most notorious gangster on the planet, with a net worth of $1.1 billion. The leader of the infamous Sinaloa Cartel, El Chapo has been accused of importing over 180,000 kilos of cocaine into the US. Drug-enforcement experts estimate his cartel's annual revenues at greater than $3 billion.

Cunning and evasive, El Chapo escaped from a Mexican prison in July (not for the first time) by way of a labyrinthine tunnel he may have paid $50 million in bribes and construction costs to have built. The US State Department is offering a reward of up to $5 million to anyone with information leading to his arrest.
