Investigations are ongoing into the circumstances leading to his death at the CasaSur hotel. Toxicology tests identified traces of alcohol, cocaine, and a prescription antidepressant in Payne’s system, while a post-mortem examination attributed his death to "multiple trauma" and "internal and external hemorrhage" linked to the fall. Argentine authorities have conducted nine raids around Buenos Aires and are also probing into Payne’s damaged laptop and other electronic devices recovered from the scene.
