(Fox News) Brittany Murphy's parents are at odds over their daughter's cause of death.
Andrea Bertolotti, the 87-year-old estranged father of the deceased actress, submitted a hair sample for independent testing that revealed his daughter had abnormal amounts of heavy metals in her system at the time of death. This led some to speculate that the "Clueless" star could have been poisoned.
According to Radar Online, Bertolotti is also suggesting that Murphy, who was said to be convinced she was under surveillance in the weeks prior to her death, was targeted by government rogues mistrustful of her daughter's support of Department of Homeland Security (DHS) whistleblower turned filmmaker and journalist Julia Davis.
