The nephew of drug kingpin Pablo Escobar found a plastic bag hidden in the wall at one of his uncle's houses with £ 14 million of cash.
He had a 'vision' which showed him where to look for the money in the Medellin, Colombia apartment, Nicolas Escobar said.
It was not the first time he had found money in unusual places where his uncle used to hide from the authorities, he told the local media.
It was said that Escobar, who died in a police shooting in 1993, was the seventh richest person in the world at the peak of his power.
In his many properties across Colombia, the 'King of Cocaine' reportedly hid millions.
By the time of his death, he had amassed an estimated net worth of US $30 billion, equivalent to $59 billion today.
For years since his death, rumours of his hidden fortunes have been circulating.
He also found a gold pen, satellite phones, a typewriter, a camera and an undeveloped film roll, Nephew Nicolas told Colombian TV channel Red+ Noticias.
He said: 'I saw a man entering the place and disappearing every time I sat in the dining room and looked toward the car park.
'[Inside] the smell was astonishing. A smell that's 100 times worse than the one that died.'
Many of the old notes stashed on the wall had decayed and were no longer usable.
Pablo Emilio Escobar Gaviria was a drug trafficker from Colombia.
He controlled over 80 per cent of the cocaine shipped to the US during his time at the helm of the Medellin Cartel.
This earned him the rank of one of the world's ten wealthiest people in Forbes Magazine.
In the early 1970s, Escobar joined the cocaine trade, collaborating to form the Medellin Cartel with other criminals.
Escobar earned popularity by sponsoring charity projects and soccer clubs, despite his role as a drug lord.
However, Escobar's terror campaigns resulted in the murder of thousands of people who turned the public against him.
More than 15 tons of cocaine were reportedly smuggled each day, netting the Cartel as much as $420 million a week.
Colombian law enforcement finally caught up to Pablo Escobar on December 2, 1993 in a middle-class neighborhood in Medellin.
A firefight ensued and, as Escobar tried to escape across a series of rooftops, he and his bodyguard were shot and killed.
