Liam Payne had multiple drugs in his system at the time of his death: sources

Toxicology test results shed light on the tragic death of Liam Payne last week.

A partial autopsy revealed that the former One Direction singer, who died at age 31, had multiple substances in his body when he fell to his death from the third-floor balcony of his hotel room in Buenos Aires, Argentina, on October 16 crashed, sources tell ABC News. These substances included “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 cocaine. According to the sources, an improvised aluminum pipe for taking drugs was also found in his hotel room.

Payne's body will remain in Argentina until the autopsy is completed, the sources also told ABC News.

Before Payne's death, hotel officials called authorities and asked them to “send someone urgently” because a guest was reportedly “drunk on drugs and alcohol.”

“We need to send someone urgently because I don't know if the guest's life is in danger because he is in a room with a balcony and we are worried that he might do something that is life-threatening,” the worker opposite said the emergency services.

When authorities arrived about seven minutes later, Payne's body was found in the hotel's courtyard, where he was pronounced dead at the scene, Alberto Crescenti, the director of SAME, Buenos Aires' emergency medical service, told ABC News.

A preliminary autopsy report from the Argentine prosecutor's office found that Payne died of “multiple trauma” 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.

The Buenos Aires Ministry of Security previously told ABC News that “multiple substances and broken items” were found in Payne's hotel room.

A hotel employee suspected of supplying Payne with drugs on the day of his death was questioned by officers, Argentine state police told ABC News. This employee has not been arrested and no charges have been filed against him at this time.
