3 people face charges as his body returns to UK

The internal and external injuries Payne suffered were the result of his fall from a third-story balcony, and third-party involvement has been ruled out, according to Madrea. Tests showed Payne had traces of alcohol, cocaine and a prescription antidepressant. Investigators believe he was in a state of partial or complete unconsciousness and ruled out the possibility that the fall was voluntary.

The statement said: “From the beginning of the investigation and within a few days, comprehensive and careful measures were taken to understand the circumstances of the artist's death.” According to the statement, this included several dozen witness statements, including hotel employees, family and friends, medical professionals, Biochemist and psychiatrist.

“A detailed analysis of more than 800 hours of video footage from various surveillance cameras in the hotel and others on public streets was also carried out,” the statement said.

In investigating what led to Payne's death, Argentine authorities “conducted the forensic extraction of the contents of (Payne's) cell phone. Their calls, messages, chats in messaging applications and social networks were then analyzed.”
