Former One Direction singer Liam Payne had multiple drugs including crack cocaine and methamphetamine in his system when he fell to his death from a hotel balcony in Argentina, according to anonymous Argentinian sources familiar with the initial toxicology reports. The British singer and former One Direction member died last week at the age of 31 after plunging from a third-floor hotel room in Buenos Aires. ABC News and TMZ reported that a cocktail of drugs called “pink cocaine” – containing methamphetamine, ketamine and MDMA – had been found during a partial autopsy, along with crack cocaine and benzodiazepine. Both outlets cited anonymous sources familiar with the preliminary tests. Associated Press reported an anonymous official had said the preliminary toxicology report suggested evidence of exposure to cocaine, but stressing that these initial results don’t offer an accurate reading of just how much was circulating in his blood when he died. The final toxicology results are not expected to be made public for some weeks. Associated Press reported that the official spoke on condition of anonymity because he was not authorised to brief journalists. The preliminary report was widely reported in local media on Monday. Argentina’s public prosecution is investigating the case, which is not uncommon when a death is sudden or unexpected. Payne’s autopsy concluded that the traumatic injuries that caused his death were consistent with his three-story fall from the hotel window. Prosecutors have ruled out anyone else being involved. Argentinian investigators found what appeared to be narcotics and alcohol strewn about broken objects and furniture in 31-year-old Payne’s hotel room, leading the public prosecution to surmise Payne had suffered a substance abuse-induced breakdown around the time of his fall. The prosecution said Payne could have plunged from his hotel room balcony in a state of “semi or total unconsciousness”. Photos purportedly taken from inside Payne’s hotel room published by local media showed snowlike powder left on a table and a smashed-in TV screen. Police also discovered a blister pack of clonazepam, a central nervous system depressant, and over-the-counter medications scattered among Payne’s belongings. Shortly before Payne’s death, the hotel manager called 911 to report a guest acting aggressively and under the influence of drugs and alcohol. Investigators are also trying to figure out who sold Payne the drugs he took at the CasaSur hotel in Palermo, a chic neighbourhood of the Argentinian capital. Police have taken statements from at least three hotel employees, as well as two women who visited Payne’s hotel room a few hours before his death. Fans and major pop industry figures around the world have reacted with an outpouring of grief. The late singer’s father, Geoff Payne, was still in Buenos Aires meeting with the prosecutors and other local officials on Monday in an effort to organise the repatriation of the remains. Argentinian authorities expect to release the body next week, clearing the way for Geoff Payne to fly home and hold a funeral back in England, where on Sunday hundreds of fervent One Direction fans gathered to mourn the musician.
