In the documents, Bertolotti states that he disagrees with the findings in the autopsy report, writing that the "testing/toxicology was incomplete and the death of Brittany Anne Murphy Monjak was never fully investigated."
The autopsy reportedly attributed Murphy's death to community-acquired pneumonia and iron deficiency anemia.
In the lawsuit, Bertolotti requests that a judge release his daughter's hair samples so that he might investigate further.
