The family of actress Misty Upham, whose body was found Thursday at the bottom of a suburban Seattle ravine, says local police wouldn't take them seriously when they first reported her missing.

Upham, a Native American actress known for her roles in August: Osage County, Django Unchained and indie film Frozen River, went missing on October 6. Her body was discovered this afternoon at the bottom of a 150 foot ravine after a search party led by a family member stumbled across her purse.

Upham's family told reporters she suffered from bipolar disease and had recently gone off her medication, but a spokesperson told the Hollywood Reporter "The family has stated that, after seeing the body, they still do not feel that Misty Upham committed suicide."

The family has criticized the police response, telling reporters long-standing tensions between the Native American population and the Auburn police force hurt the investigation.

There is apparently a history of hostility between the Auburn police and the Muckleshoot Reservation, on which several thousand Muckleshoot reside, that falls largely within Auburn.

First and foremost," a family spokesperson 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."
