“August: Osage County” actress Misty Upham was found dead by search party in a Seattle ravine. The actress, who suffered from bipolar disorder, had been missing for more than 10 days, and her family had taken to social media to help search for her, as the local police was not cooperating.

Upham, 32, a Native American actress and activist, was found dead Thursday night in a ravine by a search party that included her uncle Robert Upham, according to the Hollywood Reporter. The group of three had gone to search for her Thursday night when they discovered her body

“We waited at the site where the team found the body,” said Tracy Rector, a Seattle filmmaker and friend of Upham’s. “It took about five-and-a-half hours to confirm. Then we gathered around the body to say prayers, and now we’re all gathered at the church.”

Her father, Charles Upham, confirmed the body’s identity and the Kings County Coroner’s Office will release a statement later on Friday. The cause of death remains unknown.

However, the family wants to emphasize the Auburn Police Department’s lack of involvement in the search for Misty.

"First and foremost," Rector told the Hollywood Reporter, "the family wants everyone to know that the Auburn police did not help with this situation at all. They refused to help. When she disappeared on Oct. 5, the family knew something was seriously wrong -- it was out of character for her to be gone so long without being in touch -- and they repeatedly went to the police, who insisted there was no cause for concern."

The Upham family reported Misty missing on Oct. 6, but the local police department did not list her because she left on her own free will despite her parents worries about her mental health state.

Hollywood began reacting to the actress’s death on social media and in interviews. “August: Osage County” costar, Juliette Lewis, expressed her sadness on Twitter.

Her other costar, Meryl Streep, told Hollywood Reporter, “So sad to hear this news. All our thoughts are with her family and her beautiful spirit.”
