Natasha Jaitt claimed to have evidence about a number of well known politicians abusing children.
Jaitt, 41, said after her claims, she had been receiving death threats and was the victim of rape.
The model's naked body was found in a bed at a private house party in Buenos Aires, Argentina.
She is believed to have gone to the party with friend Raul Duarte to meet the owner of a property rented out for private parties.
Autopsy results show she suffered multiple organ failures, with cocaine residue found in her nose.
But according to her brother, the mum-of-two never took drugs after being warned by doctors it could be fatal if mixed with her medication.
Her lawyer and brother have told local media her death may have been murder.
