Guzman's fortune is estimated at $1 billion, making him the biggest drug lord in his country currently. According to a report by India Times, here are a few other things you need to know about the drug lord:
1. His full name is Joaquín Archivaldo Guzmán Loera, and he started selling oranges and soft drinks soon after he turned 6.
2. Stricken by poverty, Guzman started growing marijuana and poppies at 15. He said that was the only way for him and his impoverished family to survive.
3. Chapo does not consider himself a violent man.
4. If you ask him the rights and wrongs of his business, he would tell you that "drugs destroy."
5. He managed to escape jail twice and remained one of the world's most wanted criminal for a very long time.
6. But the most surprising of all - Despite being the world's deadliest drug lord, Guzman hasn't touched drugs in 20 years. He tried them when he was very young, but has never been an addict.
