Misty Upham, the “August: Osage County” actress who was found dead in Auburn, Washington in October, died of blunt-force injuries to her head and torso.
According to an update from the King County Medical Examiner’s office on Thursday, however, the manner of death is still undetermined.
The coroner concluded that the 32-year-old actress died on Oct. 5, the day she first disappeared from her sister’s apartment on the Muckleshoot Indian Reservation, 16 miles east of Tacoma.
The Auburn Police Department is still investigating the suspicious death that began making headlines after Upham was reported missing by her family on Oct. 6. Her purse and identification were found near her body at the bottom of a 150-foot embankment. Police have said there were no signs of foul play.
Upham’s family’s theory about her death is that she slipped and fell off of the embankment.
“We believe that Misty’s death was accidental. She did not commit suicide,” a the family said in a statement. “We believe she ran into the wooded area behind her apartment to hide from the police. The area in question has a hidden drop off and evidence suggests that she slipped and fell off of the steep embankment when she tried to get out of a view from the road. She simply did not see the drop off.”
