Brittany Murphy Death Update: The death of Brittany Murphy, known for her roles in such films as "Girl, Interrupted" and "8 Mile," is subject of debate that split the Murphy family. 

Brittany Murphy's father, Angelo Bertolotti, believes his daughter was poisoned because of contact with a government whistleblower. The actress' mother, Sharon Murphy, disagreed strongly. Julia Davis, the investigative reporter who's story is at the heart of the conspiracy at the center of the controversy, clarified media discrepancies to Kpopstarz.According to CNN, the Los Angeles County coroner ruled Murphy's death a combination of pneumonia, iron deficiency and intoxication from several drugs.

But Julia Davis, who co-starred with the actress in "Girl, Interrupted," believes Murphy was "not on drugs like so many speculated."  

Julia Davis was a stunt double for Angelina Jolie, who costarred with Brittany Murphy in "Girl, Interrupted." She was also an armed Customs and Border Protection Officer with the Department of Homeland Security who blew the whistle on security holes that allowed people from countries deemed as terrorist to enter the United States. Her work was featured by the National Whistleblowers Center.

"There have been so many suspicious symptoms," Davis told KpopStarz in an exclusive interview on Monday. Davis says Murphy "was followed and investigated ...because of her participation in my case."

According to According to Britain's MailOnline, The Carlson Company, which conducted toxicology tests at the request of Murphy's father Angelo Bertolotti last year, the actress was experiencing symptoms of heavy metal poisoning at the time of her death, including headaches, dizziness, abdominal cramps, coughing, sweating, disorientation, wheezing, congestion and pneumonia.

The Daily Mail reported last year that Bertolotti has said he believes his daughter was poisoned because of contact with Davis.

Davis said "Mr. Bertolotti never said she was poisoned because of it." He only commented on the surveillance and investigation. 

In November 2013, the actress's mother, Sharon Murphy, wrote an open letter in The Hollywood Reporter claiming "Brittany never cooperated with Julia Davis, never signed any statement in support of her, never met with her and barely knew she existed."

"Davis did try to contact Brittany through her agent, but all she got back was a letter from [her agent] which we have, telling Davis that their client knew nothing about her claims and would not meet with her," Murphy's mom added.
According to Davis, while working as a Customs and Border Protection Officer,  "I made a whistleblowing disclosure to the FBI/JTTF about 23 people from terrorist countries being admitted into the U.S. without proper checks and system enrollment."

One week before Sharon Murphy published her statement in the Hollywood 

Bertolotti claimed his phone was tapped after he voiced support for Davis.

"Mr. Bertolotti never identified any suspects in Brittany's murder," Davis said."He merely pointed out that his daughter was terrorized and placed under surveillance by the Department of Homeland Security."

Sharon Murphy calls the whole thing an attempt to "smear my daughter's memory by a man who may be her biological father but was never a real father to her in her lifetime."

"[The Carlson Company] report conveniently ignores what any good scientist will tell you; a hair sample can be affected by many outside factors, including hair dye, hair spray, prescription medications, foods, smoking the occasional cigarette and environmental factors," she wrote in her November statement.

"One cause we now know may have been toxic mold that was eventually discovered in that house, which may have been what really killed her. We will never know for sure. However, we do know the Los Angeles County Coroner did extensive tests and found that she died of natural causes. And now she is a real living angel in heaven."

Davis clarified, that the "LA Coroner specifically investigated the mold allegations and found them 100% false. Google it." 

The film "Top Priority: The Terror Within" is a documentary about the events that was written by Davis and directed by Asif Akbar. It premiered at the Academy of Motion Picture Arts and Sciences on May 16, 2012.
