Liam Payne may have been ‘semi-conscious or completely unconscious’ when he fatally fell from a third floor hotel balcony, Argentina’s prosecutor office has said.

The 31-year-old star plunged 45ft from the third floor into the courtyard of the Casa Sur Hotel in Argentina’s capital yesterday, before medics confirmed his death. 

Detectives confirmed that a series of substances were seized from the hotel room ‘indicating previous situation of alcohol and drug consumption’. 

It contradicts police reports that the 31-year-old had ‘jumped’ from the third-floor hotel balcony.

Prior to Payne’s death, hotel staff franticly called 911 regarding ‘an aggressive man who could be under the influence of drugs or alcohol’ who was ‘smashing up his room’.

Hotel guests claimed to hear ‘violent noises’, and assumed there was construction work was ongoing in the room, according to the BBC. 

Photos have also emerged from inside his luxury suite, appearing to show a trashed television, surfaces covered with tin foil and white powder as well as scorch marks on the wooden surface.

A preliminary report into the popstar’s death said ‘everything indicates’ Payne was alone when he died. 

According to local news outlets, Payne was taken to the Judicial Morgue where medical staff conducted an autopsy last night. 

After conducting a preliminary report, they suspect into Payne died from external and internal bleeding after sustaining several injuries.

Authorities have requested further tests including toxicological, biochemical, and histopathological examinations. 

The prosecutor’s office said forensic reports showed no injuries were observed that suggest third-party involvement and that the autopsy is compatible with a fall from height. 

However officials are still launching a probe into the ‘possible involvement of third parties’ in the events before his passing. 

It comes as police investigating the sudden death of One Direction star Liam Payne are searching for two ‘key witnesses’ who could be among the last people to see him alive.

The 31-year-old singer died instantly after suffering multiple injuries that led to ‘internal and external haemorrhaging’, when he fell from a third-floor balcony at a hotel in Buenos Aires, Argentina, on Wednesday.

Argentine investigators are now hunting for two women who spent time with Payne at the Casa Sur hotel the night before his shock death.

Both women are said to have left the hotel yesterday after waiting for the star in the lobby, Argentine outlet Infobae reports. 

There is no indication that the women could be involved in his death, but police hope they can help piece together Payne’s final moments before he plunged to his death at around 5pm local time. 

Payne’s girlfriend, Kate Cassidy, had returned to Florida four days prior to his death, telling her followers ‘I just needed to go home’ after their planned ‘five-day trip’ was extended to two weeks.

As more details emerge from the hours before Payne’s death, one hotel guest staying in the same hotel as Payne recalled hearing ‘violent noises’.
