Gustavo de Jesús Gaviria Rivero, Pablo Escobar’s cousin and closest confidant, was a powerful force behind the Medellín Cartel, operating from the shadows until his death at the hands of Colombian police on August 11, 1990, at the age of 43. Many consider Gaviria to have been the true mastermind of the cartel, as its downfall accelerated after his death, leaving Escobar increasingly vulnerable.
Born on December 25, 1946, Gustavo de Jesús Gaviria Rivero was nearly three years older than his cousin, Pablo Emilio Escobar Gaviria, who was born on December 1, 1949.

The two grew up together in the Colombian town of Envigado, forming a tight bond. According to Mark Bowden, author of Killing Pablo: The Hunt for the World’s Greatest Outlaw, both came from well-educated, middle-class families, making their decision to abandon conventional careers for organized crime all the more surprising.
Gaviria revolutionized the cartel’s smuggling operations, favoring innovative methods over brute force. Rather than flying cocaine directly into the U.S., he used legitimate cargo ships carrying household appliances, hiding the drug inside refrigerators and televisions.

According to The Wall Street Journal, cocaine was also smuggled in Guatemalan fruit pulp, Ecuadorian cocoa, Chilean wine, and Peruvian dried fish. In one particularly creative scheme, the cartel soaked blue jeans in liquid cocaine, allowing chemists to extract the drug upon arrival in the U.S.

The Medellín Cartel’s profits were staggering. Producing a kilogram of cocaine cost around $1,000, yet it could sell for as much as $70,000 in the U.S. The cartel’s pilots were so expendable that they often flew one-way trips, ditching their planes in the ocean before swimming to awaiting ships.
While Pablo Escobar craved power, Gustavo Gaviria was primarily focused on money. With extensive global connections, Gaviria played a crucial role in the cartel’s cocaine distribution network. His death on August 11, 1990, marked a turning point.

Colombian police tracked him down in an upscale Medellín neighborhood and killed him—officially, in a shootout. However, Escobar insisted his cousin had been kidnapped, tortured, and executed.
“When Gustavo was killed, the police claimed it was in a shootout,” Bowden explained. “But Pablo always claimed he’d been kidnapped, tortured, and executed. The phrase ‘killed in a shootout’ kind of became a euphemism.”

Gaviria’s death sent shockwaves through Colombia, shattering a delicate peace agreement between the cartels and the newly elected president, César Gaviria (no relation). The result was several more years of extreme violence.
Without his cousin’s financial expertise and logistical prowess, Pablo Escobar’s empire began to crumble. Forced into hiding, Escobar became a fugitive. On December 2, 1993, he met the same fate as his cousin—gunned down by Colombian police.
He had a son named Gustavo Gaviria Restrepo.
He had a brother named José Luis Gaviria Rivero who died.
