Pablo Emilio Escobar Gaviria was a Colombian drug lord and narcoterrorist. ... He was often called "The King of Cocaine" and was the wealthiest criminal in history.
He was born in Rio negro, Colombia and grew up nearby Medellin. He studied briefly at Universidad Autónoma Latino Americana of Medellin but left without a degree. He later began to engage himself in criminal activity that involved selling contraband cigarettes and fake lottery tickets, and he participated in motor vehicle theft. In the 1970s, he began to work for various contraband smugglers, often kidnapping and holding people for ransom before beginning to distribute powder cocaine himself, as well as establishing the first smuggling routes into the United States in 1975. 
His infiltration to the drug market of the United States expanded exponentially due to the rising demand for cocaine and, by the 1980s, it was estimated that 70 to 80 tons of cocaine were being shipped from Colombia to the United states on a monthly basis. His drug network was commonly known as the Medellin Cartel, which often competed with rival cartels domestically and abroad, resulting in massacres and the murders of police officers, judges, locals, and prominent politicians.
I believe this man is very brutal and he doesn't joke with his business. Nothing stand in his way...
Nice one.
