US influencer Kate Cassidy, 25, hit back at critics who accused her of abandoning Liam in Argentina where he fell to his death from a hotel balcony last October.
Grassi was one of the three men identified alongside Martin in the last harrowing photo of Liam to emerge showing him being carried back up to his room from his hotel lobby shortly before his fall.
The other two men now in the clear are Esteban Grassi, the chief receptionist at CasaSur Palermo Hotel in Buenos Aires who made a 911 call moments before Liam died, and its head of security Gilda Martin.
It came as part of the move to drop manslaughter charges against two hotel worked and Liam's friend Rogelio "Roger" Nores in relation to his death.
LIAM Payne’s devastated girlfriend broke her silence about the One Direction star’s final days — and her regret at leaving him alone before his death.
