Pablo Escobar's nephew has just discovered a plastic bag worth $18 million worth of money hidden in the wall of one of his uncle's houses.

Nicolás Escobar told the Colombian media that "a vision" suggested where to search for money in the apartment in the city of Medellín where he lives.

It wasn't the first time he discovered money in ways his uncle used to escape arrest. He said since Escobar allegedly concealed millions in property.

Pablo Escobar is the seventh-richest individual on the world at the height of his career. In 1993, he died in a police shooting.

After his assassination, rumors of Escobar's secret riches have spread in Medellín. The United States spent decades battling the Colombian state to avoid his extradition.

A whopping $18 million behind a wall? How is it possible?

In an interview with the Colombian Red+ Noticias TV channel, Nicolás Escobar also discovered a typewriter, satellite phones, a gold pen, a camera, and a film roll that had yet to be made.

"Every time I sat in the dining room and looked towards the car park, I saw a man entering the place and disappearing," he said.

"The smell [inside] was astonishing. A smell 100 times worse than something that had died."

Nicolás Escobar said that some of the decades-old banknotes had decayed and no longer useable. His nephew is staying in the said apartment for the past five years.

He said in the interview that Pablo Escobar followed him several times. Nicolás added people searching for the Escobar abducted him. According to him, they tortured him for seven hours.

Who is this notorious drug lord?

Pablo Escobar was born in 1949 in Rionegro, Colombia, and founded a cocaine cartel in the 1970s in Medellín.

The group supplied approximately 80 percent of the cocaine imported into the United States at its most successful stage.

For seven years, his fortune catapulted him onto the Forbes ranking of global billionaires. Escobar avoided arrest after the US released an extradition warrant and his crew attacked officials, police and journalists.

In total, authorities assumed Escobar is liable for about 4,000 killings.

His modest origins made him famous with some of the Colombians whose patronage he cultivated by spending vast sums of money and investing in Medellín's impoverished communities.

Since it's drug money, checking Escobar's wealth is challenging. However, figures run as high as $30 billion.

For seven years running, from 1987 until 1993, Escobar made the Forbes list of world billionaires. He was ranked as the world's seventh-richest man in 1989.

In 1991, authorities detained Escobar, who is also known as "El Patron." Officials also imprisoned him in a self-designed jail called the Cathedral. That is where he could pick prisoners and begin his activities.

The Escobar cartel, officials believe, is behind more than 5,000 killings between 1989 and 1993 alone.

More than 60 million people viewed the Netflix series "Narcos," which spent three seasons concentrating on the drug lord, became obsessed with Escobar.

Brazilian actor Moura Wagner, who spoke of his happiness when he finally quit playing the part, played Escobar in the show.
