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

Sources previously told ABC News that a partial autopsy also revealed 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, benzodiazepine and crack. According to sources, an improvised aluminum drug pipe was also found in his hotel room.

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 to two female escorts who were allegedly called in the lobby of the hotel where Payne was staying at the time of his death, via the app. According to sources, he did not pay the escorts.

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

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

Payne’s father, Geoff, has been in Buenos Aires since October 18 trying to get his son’s body back 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 the third floor of his hotel room in Palermo, Buenos Aires, according to Argentine police. He was 31 years old.

Emergency services were called to deal with the man, who was acting erratically and possibly under the influence, Alberto Crescenti, director of the Buenos Aires SAME emergency medical service, told ABC News earlier. Payne’s body was found on the hotel’s patio, where he was pronounced dead at the scene, Crescenti said.

A preliminary autopsy report from Argentine prosecutors on Oct. 17 found Payne died of “multiple injuries” and “internal and external bleeding.”

Twenty-five injuries are reported on Payne’s body. The report stated that Payne’s head injuries were sufficient to cause death and that the cause of death was related to the height of the fall.
