Brittany Murphy "was poisoned by government spooks in revenge for star's support of whistleblower," according to the actress's father. Brittany Murphy's father is calling on the Los Angeles Police Department to re-open the investigation.

Angelo Bertolotti, 87, claims that Brittany Murphy and her husband were poisoned because they supported a Department of Homeland Security whistleblower Julia Davis. The whistleblower claimed that low security let terrorists coming over the Mexican border into the U.S. Brittany Murphy's father says Julia Davis' supporters were spied on. Bertolotti and Davis writing a book, Britt" and Davis will release a documentary called "The Terror Within" about the conspiracy charge.

Brittany Murphy died December 20, 2009. At the time, the Los Angeles County Coroner gave the cause of death as pneumonia. Brittany Murphy's husband, British screenwriter Simon Monjack, 40, died in the same house five months later in the same house.

Brittany Murphy's father ordered a new toxicology report that found ten heavy metals in the her system. The findings indicate that rat poison may have caused the Brittany Murphy's death. The legal action also names arsenic as a possible cause of death. Brittany Murphy's father had hair, blood and tissue samples tested by an independent laboratory.

Brittany Murphy's father claims that his daughter was under surveillance by government spies at the time of her death. Bertolotti says Brittany Murphy's phone was tapped and that after she made comments supporting the Department of Homeland Security whistleblower she was terrorized.

Julia Davis says she once worked as a stunt double for Angelina Jolie, who costarred with Brittany Murphy in "Girl, Interrupted."

Julia Davis claims that her exposure of border security flaws that let terrorists into the U.S. got her branded as a "domestic terrorist." She exposed security flaws after working as a border security guard in California.

A family member told MailOnline  "I called it two weeks after it happened. You just don't have two people die like that under those circumstances.'

Officials say there is no evidence to support Brittany Murphy's father's claims.

The toxicology report says "If we were to eliminate the possibility of a simultaneous accidental heavy metals exposure to the sample donor then the only logical explanation would be an exposure to these metals (toxins) administered by a third party perpetrator with likely criminal intent."

Brittany displayed all symptoms of heavy metal poisoning at the time of her death. She experienced headaches, dizziness, abdominal cramps, coughing, sweating, disorientation, wheezing, congestion and pneumonia. Her husband exhibited similar symptoms before his death.

In a YouTube video Davis claims her supporters were followed by Blackhawk helicopters and wiretapped.

Bertolotti told Los Angeles-based Fleur De Lis Film Studios, "They were, in fact, under surveillance, including helicopters. Their telephones were wiretapped, Brittany was afraid to go home, because of the sneak-and-peek incursions into their residence and other terror tactics she suffered after speaking out in support of Julia Davis and being named as a witness in her lawsuit against the Department of Homeland Security. Brittany was afraid to go home, because of the sneak-and-peek incursions into their residence and other terror tactics she suffered."
