Three people have been charged with “the crime of abandonment of a person with subsequent killing, supply and brokering of narcotics” in connection with the death of former One Direction singer Liam Payne last month, Argentine prosecutors said in a statement on Thursday.

The three people charged in connection with Payne's death include a person who accompanied Payne “daily during his stay in the city of Buenos Aires.” That person was charged with the “crime of abandonment of a person resulting in homicide,” a charge that carries a possible sentence of 5 to 15 years in prison, prosecutors said.

The other two people charged are each charged with the “crime of delivery of narcotics,” prosecutors said. They include a hotel employee who is believed to have supplied Payne with two supplies of cocaine during his stay at the hotel, and a drug supplier who is accused of supplying Payne with drugs “at two separate times on October 14,” according to prosecutors.

According to Argentine State Police, Payne died on October 16 after falling from his third-floor hotel room in Palermo, Buenos Aires. He was 31 years old.

Payne's father, Geoff Payne, left Buenos Aires for Britain on Wednesday with his son's body. He had been in the country for weeks, waiting for authorities to allow him to return to Britain with Payne's body after the criminal investigation was completed.

The inquest into Payne's death found that he was “not fully conscious or in a state of noticeable unconsciousness or unconsciousness at the time of the fall,” leading prosecutors to rule out “self-harm of any kind.”

“For the public prosecutor, a conscious or voluntary act by the victim would also be ruled out in this situation, since in his condition he neither knew what he was doing nor could understand it,” said the public prosecutor.

“In the moments before his death and for at least his final 72 hours, Payne had only traces of polydrug use of alcohol, cocaine and a prescription antidepressant in his system,” toxicology test results showed, prosecutors said.

“All injuries suffered by Payne were consistent with those caused by a fall from height and excluded self-harm of any kind and/or physical interference by third parties,” the prosecution said.

Following the death of Liam Payne, police raid the homes of hotel workers

The news comes after two officers involved in the investigation confirmed to ABC News that police searched the homes of hotel workers and a friend of Payne's.

A total of nine raids were carried out, during which police confiscated cell phones, a hard drive, three laptops and drugs, including marijuana, according to prosecutors.

Last week, multiple sources with direct knowledge of the investigation told ABC News that police had reviewed CCTV footage that appeared to show several drug exchanges between a dealer and a hotel employee before Payne's death. Sources said at the time that police were investigating whether the hotel employee had supplied Payne with drugs.

Previously, sources told ABC News that a partial autopsy also found he had several substances in his system that day, including “pink cocaine” – a recreational drug that is typically a mixture of several drugs, including methamphetamine, ketamine , MDMA and others – – as well as cocaine, benzodiazepines and crack. According to the sources, an improvised aluminum pipe for taking drugs was also found in his hotel room.

A preliminary autopsy report from the Argentine prosecutor's office revealed on October 17 that Payne died of “multiple traumas” and “internal and external bleeding.”

Twenty-five injuries were 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 his fall.
