PABLO ESCOBAR (aka King of Cocaine)
Escobar was responsible for killing about 4,000 people, including an estimated 200 judges and 1,000 police, journalists, and government officials.(600 Police officers According to Wikipedia)
Escobar is said to have smuggled cocaine into plane tires. Depending on how much product pilots flew, they could earn as much $500,000 per day.
He started off as a criminal in the streets of Medellin in his teens, smuggling cars, tombstones, cigarettes and even kidnapped people for ransom. He entered the drug business in the 1970s.
In 1989, Forbes listed him as the 7th richest man in the world with assets close to around $25 Billion($30 Billion in other Sources ).
During the height of its operations, the Medellín Cartel brought in more than US $70 million per day (roughly $22 billion in a year). Smuggling 15 tons of cocain per day, worth more than half a billion dollars, into the United States, the cartel spent over US $1000 per week purchasing rubber bands to wrap the stacks of cash, storing most of it in their warehouses. Ten percent (10%) of the cash had to be written off per year because of "spoilage", due to rats creeping in and nibbling on the bills they could reach.(In the 1980s, Escobar's Medellin cartel was responsible for 80 percent of the cocaine that was sent to the United States.)
His drug trade flourished so much that he was smuggling nearly 15 tonnes of cocaine every day!
In an attempt to change the laws of extradition, Escobar offered to pay off Colombia’s national debt – an estimated 10 billion dollars.
