brittany-murphy-wrongful-de.jpgBrittany Murphy's father, Angelo Bertolotti, is suing the Los Angeles County Coroner's Office because he claims her autopsy was "never fully investigated.”

Bertolotti, who is also suing the Los Angeles Police Department, has requested samples of his daughter’s hair for his own testing. “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 in a press release.

In 2009 the coroner’s office ruled that the 32-year-old actress died of pneumonia, anemia and prescription drug intoxication, but Bertolotti believes toxic mold in her Hollywood Hills home could have caused her death, according to The Hollywood Reporter.
