Coroner’s Assistant Chief Ed Winter said he understands why Bertolotti filed the case.

“He’s trying to get a resolution to his daughter’s death,” Winter said.

Murphy became unconscious in her Hollywood Hills home on Dec. 20, 2009, after exhibiting flu-like symptoms. She was pronounced dead at Cedars-Sinai Medical Center.
