NSR : What happens to drug money the government finds?

I am watching 60 Minutes about a Super Cartel and how they found 41 million in 1 shipment being hidden. They think billions come in every year. Escobar was super rich he Forbes said he was one of the 20 riches people on earth. He died but WTF did his money go?

Does US take it? Do they split it with Colombia? Or it all get stolen?
