Sources say police never believed Payne’s death was a suicide or intentional.

Earlier, sources told ABC News that a partial autopsy also found that he had several substances in his system that day, including “pink cocaine” — a recreational drug that is usually a mixture of several drugs, including methamphetamine, ketamine, MDMA and others – as well as cocaine, benzodiazepines and crack. A makeshift aluminum pipe for ingesting drugs was also found in his hotel room, sources said.

According to multiple sources with direct knowledge of the investigation, police also identified the presence of two female escorts at the hotel in the hours before Payne’s death.

Payne offered $5,000 for two female escorts who were allegedly summoned from the hotel lobby where Payne was staying at the time of his death via an app. He did not pay the escorts, sources said.

Sources also noted that a Rolex was also found missing from Payne’s hotel room.

Payne’s body is expected to be handed over to his family next week, sources added.

Payne’s father, Geoff, has been in Buenos Aires since Oct. 18 trying to repatriate his son’s body for burial in England, according to officials at the British Embassy in Buenos Aires. The release of Payne’s body depends on the court’s findings in the criminal case.

Payne died on October 16 after falling from his top-floor hotel room in Palermo, Buenos Aires, according to Argentina’s state police. He was 31 years old.

Emergency services were called to deal with a man who was acting erratically and possibly under the influence, Alberto Crescenti, director of SAME, Buenos Aires Emergency Medical Services, previously told ABC News. Payne’s body was found in the courtyard of the hotel where he was pronounced dead at the scene, according to Crescenti.

A preliminary autopsy report by the Argentine Prosecutor’s Office revealed on October 17 that Payne died of “multiple trauma” and “internal and external bleeding”.

Twenty-five wounds were reported on Payne’s body. The report said Payne’s head injuries were sufficient to cause death, and the cause of death was related to the height of his fall.
