The talented vocalist, known for his time on The X Factor and as a member of the globally successful boyband One Direction, was discovered to have traces of alcohol, cocaine, and a prescribed antidepressant in his system. Toxicology reports and a post-mortem analysis revealed that his cause of death was "multiple trauma" stemming from the fall, which resulted in both internal and external haemorrhage.

Ongoing investigations by authorities have involved multiple home raids in Buenos Aires and scrutiny of Payne's damaged laptop and other electronic devices in hopes of unraveling further details surrounding this heartbreaking incident.
