Brittany Murphy’s father has sensationally claimed that the tragic ‘Clueless’ actress was poisoned to death by after offering her celebrity backing to a whistleblower fighting the government.

Angelo Bertolotti, 87, alleges that at the time of her death his daughter was under surveillance from shadowy government operators who wiretapped her phone and terrorized her after she spoke out in support of a Department of Homeland Security whistleblower.

Julia Davis, who claims to have once worked as a stunt double for Angelina Jolie, says Brittany was being persecuted for standing up for her.

Davis claimed she was branded a ‘domestic terrorist’ after she exposed security flaws that were allowing terrorists to sneak into the U.S. while she was working as a border security guard in California.

The extraordinary claims are what drove Brittany’s father to campaign to have a separate toxicology test conducted on the star. 

The new report found rat poison may have caused the shock death – in stark contrast to the official coroner’s report that concluded it was natural causes.

The latest twist to the growing mystery over the actress’s death came as relatives called on police in Los Angeles to re-open the investigation.

‘I called it two weeks after it happened,’ one family member told MailOnline. ‘You just don’t have two people die like that under those circumstances.’

Officials insist there is no evidence to support a more sinister motive behind 32-year-old Brittany’s sudden death in the bathroom of her Los Angeles home on December 20, 2009.
