Brittany Murphy - Murphy's Father Demands More Answers About Daughter's Death

Angelo Bertolotti has filed suit against the Los Angeles Police Department and the Los Angeles Coroner’s Office, asking the authorities to re-open the investigation into his daughter's 2009 death from reported pneumonia, anaemia and excessive use of prescription medications.

In court papers filed in Los Angeles on Wednesday (11Jan12), Bertolotti, who was estranged from his daughter for much of her adult life, is seeking an order to release Murphy's hair and tissue samples so they can be independently tested for toxic substances, poisons and heavy metals.

He states, "Years after my daughter’s untimely death, toxicology testing on her hair still has not been completed. (The) office of the Los Angeles Coroner and the Los Angeles Police Department admitted that such tests were not done and refused to conduct them. At this point, I am asking the court to intervene and allow me to get the specimens independently tested.

"Brittany’s hair and tissues were about to be destroyed, but I’ve paid to have them preserved, so that they could finally be examined. 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 recently announced plans to team up with screenwriter Julia Davis to write a book about his estranged daughter's life.
