Multiple sources told ABC News that hotel surveillance cameras show drug buys involving a hotel employee and a drug dealer.

Payne fell from the third-floor balcony of his hotel room in Argentina on October 16.

An autopsy revealed that there was a dangerous drug cocktail in Payne's body when he died.

The police are now actively looking for the drug dealer.

Payne has long been open about his battle with addiction.

In July 2023, he posted a video in which he said that he was sober for six months after treatment.
