Brittany Murphy's father is demanding a new investigation into his daughter's death.
Angelo Bertolotti has filed suit against the Los Angeles Coroner's Office and the Los Angeles Police Department, in an attempt to get them to do additional toxicology testing on a sample of the star's hair, and in turn re-open the investigation into her death.
An autopsy on Brittany concluded she died from pneumonia, anemia and excessive use of prescription medications in December 2009. Five months later her husband, Simon Monjak, also died, with the cause of death ruled as pneumonia and anemia.
Both Angelo and Brittany's mother, Sharon Murphy, believe the deaths were both caused by toxic mould.
Angelo said in a statement: "Years after my daughter's untimely death, toxicology testing on her hair still has not been completed. Office of the Los Angeles Coroner and the Los Angeles Police Department admitted that such tests were not done and refused to conduct them.
