Liam Payne’s distraught girlfriend Kate Cassidy has been spotted for the first time since his tragic passing. Liam’s father Geoff Payne arrived over the weekend to the hotel in Buenos Aires where his son died, and he took in the growing memorial outside. The investigation into Liam’s death continues, as ABC News reports a partial autopsy reveals he had multiple substances in his system when he fell to his death, including “pink cocaine” — usually a mix of meth, ketamine, MDMA, and others.
