Colombian drug trafficker Pablo Escobar reportedly killed some 4,000 people and was the Medellin Cartel's head during the 1980s and 1990s.In the early 1970s, Pablo Emilio Escobar Gaviria entered the cocaine trade and began buying high-grade coca from Bolivia and Peru. He processed it into cocaine, which he transported to America for distribution. He was the Colombian narcotics trafficker and head of the Medellin Cartel, an organized group of drug suppliers and smugglers based in Medellin, Colombia. He was even elected to Congress in 1982. At that point, 80 percent of the world's cocaine trade was going through Escobar, and his estimated net worth was $25 billion. While in Congress, Escobar became known for his Plata o Plomo tactic, which roughly means bribery or death.

In 1989, Escobar blew up a plane filled with innocent people in an attempt to kill one of his enemies. One hundred and seven people died when a bomb was detonated on Avianca Flight 203. In the 1980s, and up to his death in 1993, Escobar's Medellin Cartel was involved in a brutal violence campaign and murdered thousands. In 1991, Medellin's homicide rate was at the rate of 381 for every 100,000 inhabitants. Escobar reportedly killed some 4,000 people, including numerous police officers and government officials.

Some of the most prominent men in Colombia fell victim to Escobar's murderous plans, such as the head of Colombia's National Police Anti-Narcotics Unit and the Colombian Justice Minister. Escobar commanded the death of an estimated 600 police officers during his lifetime. In 1991, he faced multiple drug charges. Escobar had built his prison and choose his guards, which lasted until 1992. Later, the public found out that Escobar had abused and killed people inside his prison. The Colombian government decided to place Escobar in a real jail, but he disappeared before they could arrest him.

On Dec. 2, 1993, police forces located Escobar hiding in Medellín and shot and killed him on the roof.
