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 cause of death is still pending investigation.
Upham’s family released a press release earlier on Friday that stated their theory around Upham’s death:
We believe that Misty’s death was accidental. She did not commit suicide. 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.
The actress was reported missing by her family on Oct. 6. A three-person search party, including one family member, found Upham’s purse and ID 10 days later near the White River. They discovered a body nearby, at the bottom of a 150-foot embankment and called 911.
On Oct. 5, Police had responded to a call of a possible suicide at the apartment, but Upham was gone by the time officers arrived, according to Auburn police commander Steve Stocker. Upham’s parents told police she had been taking medication for mental health issues, Stocker said. She was listed missing a day later in the Washington Crime Information Center database.
The Native American actress, a Blackfoot, played housekeeper Johnna Monevata in “August: Osage County” and was nominated for an Independent Spirit Award for best supporting female for “Frozen River.” She also appeared with Benicio del Toro in last year’s “Jimmy P.”
