Former One Direction band member Liam Payne died Wednesday after falling from the third floor of a hotel in Buenos Aires. The exact circumstances surrounding his death are under investigation.

In the autopsy report obtained by TODAY, the Argentina National Prosecutor’s Office noted in a press release that Liam died from “polytrauma and internal and external bleeding.” The release also noted that “a series of substances were seized from the musician’s room, which would prove a previous situation of alcohol and drugs consumption.”
