Misty Upham, who appeared in August: Osage County and 2008's Frozen River has been missing for six days, according to People

The Native American actress, 32, who lives with her parents in Auburn, Wash. was last seen leaving her apartment on Oct. 5. She was reported missing by her father, Charles Upham, on Oct. 6.

Unfortunately, Upham's disappearance does not fit the criteria dictated by Washington law to be classified as a "missing and endangered person." According to Commander Steve Stocker, the person's disappearance must be "unexplainable, involuntary or suspicious."

"Our officers responded to her apartment where she lives with her parents on Sunday for a suicidal call," Stocker told the magazine. "When our officers got there, she had already packed up some belongings and left the apartment, so the officers were not able to contact or find her."

Upham's father fears his daughter may be suicidal, he told The Hollywood Reporter"She had recently changed her medication, so she was sort of having erratic behavior," he said. "She told me and her mom that we didn't have to worry about her any more. ... I thought it sounded suicidal myself, so I called the police. She's always been a suicidal person."

"She used to make [suicide] threats sometimes, but she never went through with it," he added.

According to Stocker, this was the fourth time in a year that police have been called to Upham's residence for suicide calls. It's also not the first time she's disappeared without warning.
