Actress Misty Upham – who played a housekeeper in August: Osage County and was nominated for an Independent Spirit Award for her role in 2008’s Frozen River – has been missing for six days.
Upham, 32, was reported missing by her father on Oct. 6, and was last seen leaving her apartment on Sunday in Auburn, Washington, 20 miles south of Seattle, PEOPLE confirms.
“Our officers responded to her apartment where she lives with her parents on Sunday for a suicidal call,” Commander Steve Stocker tells PEOPLE. “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.”
The following day, Upham’s father, Charles, wanted his daughter listed officially as a missing person. However, Upham does not fit the criteria for a “missing and endangered person,” per Washington state law, in which the person’s missing occurrence has to be “unexplainable, involuntary or suspicious,” according to Stocker.
“As far as the information we have, she took some things with her, she has a bus pass and even access to some money, and [the case] has been assigned to a detective, but we aren’t putting resources [to look for her],” says Stocker.
In the last year, police have responded to Upham’s apartment four times for suicide calls, and according to past police reports, this is not the first time Upham has left home, Stocker says.
“She has not been in contact with her family or friends since her disappearance,” Charles Upham wrote in a statement to media, saying his daughter had an unspecified “medical condition.”
“We are doing everything within our means to bring our daughter home safe,” her family posted on Upham’s Facebook page.
Speaking to the Hollywood Reporter, her father said, “She had recently changed her medication, so she was sort of having erratic behavior. She told me and her mom that we didn’t have to worry about her anymore. … I thought it sounded suicidal myself, so I called the police. She’s always been a suicidal person.”
He added, “She used to make [suicide] threats sometimes, but she never went through with it.” He also said that he and his daughter have never been separated for long.
“I think that she is either in a place where she can’t get help maybe she fell down and broke her leg and something, or she got in with the wrong crowd. I don’t think she would have taken her own life. I don’t want to think she is dead.”
The acclaimed Native American actress had been working recently, including filming a role alongside Jennifer Aniston earlier this year in the upcoming movie Cake.
