When Brittany Murphy died after collapsing in her home, the Coroner’s office claimed that her death “[appeared] to be natural.”
The primary cause of her death appeared to be pneumonia, but was also linked to anemia and multiple drug intoxication, which the coroner report explained as over-the-counter and prescription medications potentially used to treat an infection.
To add to the mystery, Brittany’s husband Simon Monjack was found dead at the same home mere months later, with pneumonia and anemia as the cause of death.
Brittany’s death is still a mystery, though many believe that toxic mold killed both her and her husband.

Ronni Chasen, who starred in Driving Miss Daisy and The Hurt Locker, died from gunshot wounds on November 16, 2010, on her drive home from a Hollywood film premiere.
A man believed to be associated with the murder committed suicide the next month according to The Los Angeles Times. However, the Beverly Hills Police Department deemed Chasen’s death as a random act of violence connected with a robbery.

When Elvis Presley was found dead on his bathroom floor at the age of 42, the immediate cause of his death was ruled as a cardiac arrest. However, both the competence and ethics of the attending professionals have been cast into question.
It took nearly two years after Elvis’s death for officials to make the connection between his cardiac arrest and his reliance on prescription drugs. To this day, there is still controversy about the way Elvis acquired the large amounts of drugs and how large of a role they played in his death.
