Hollywood was shocked by Brittany Murphy's untimely death back in 2009. The actress, who starred in the classic 1995 movie "Clueless," was found dead in her LA home at the age of 32. Although the LA coroner's office ruled her death as the result of pneumonia, iron deficiency anemia and prescription drug intoxication, Murphy's father never fully accepted those results and launched a private investigation into his daughter's death.

After sending hair samples to a private lab, Angelo Bertolotti says the results suggest that his daughter was poisoned.

On Monday, Bertolotti sent an e-mail to The Huffington Post saying that the lab results show that "high" levels of heavy metals were found in her hair.

"Ten heavy metals were found in abnormally high quantities... These types of heavy metals/toxic elements are commonly found in rat poison, pesticides, insecticides, etc... they may have been introduced by a third party with criminal intent," wrote Bertolotti,

He also told ABC's "Good Morning America," that "I have a feeling that there was a definite murder situation here. It's poison, yes, I know that."

In response to the new lab report, a spokesman for the coroner told ABC News that they "stand by our report."

In 2012, Bertolotti vowed to find more answers surrounding his daughter's death, telling The Hollywood Reporter, "I'm not going to rest until my daughter's untimely demise is properly investigated, which hasn't happened so far. Her case deserves more than a superficial glance," Bertolotti said.

"Vicious rumors, spread by tabloids, unfairly smeared Brittany's reputation. My daughter was neither anorexic nor a drug junkie, as they repeatedly implied," Bertolotti told the paper. "I will not rest until the truth about these tragic events is told. There will be justice for Brittany."

Ironically, Murphy's husband, Simon Monjack, died five months after his wife and his autopsy showed the causes to also be pneumonia and anemia.

According to Bertolotti, Murphy and Monjack suffered from headaches, abdominal cramps, wheezing, disorientation, congestion and pneumonia -- some of the same symptoms caused by heavy metal poisoning.

However, Bruce Goldberger, a toxicologist and the director of UF Health Forensic Medicine at the University of Florida, said the hair lab results are not enough to suggest that Murphy was poisoned. More importantly, Murphy lacked the telltale sign of heavy mental poisoning when she died: lines across her fingernails.

These lines are a key tool toward diagnosing heavy metals poisoning, Goldberger said. Without them, it's unlikely heavy metals played a role in Murphy's death.

The bottom line is these hair test results cannot be used to support any allegation of poisoning, and cannot be used to establish a cause and manner of death," Goldberger told ABCNews.com. "I feel what really contributed to her death were the drugs that she had ingested... I'm satisfied with the original findings of the coroner."
