Juliette Lewis has released a statement of sorts about the passing of her August: Osage County co-star Misty Upham, and she seems to think the late actress was murdered!

Upham, 32, had been missing since October 5, but her body was found "at the bottom of a 150 [foot] embankment near the White River," according to local authorities. Misty's father Charles told The Hollywood Reporter that he believed his daughter could have be suicidal after not taking medication for bipolar disorder.

Lewis posted the photo above and wrote:
    "Misty Upham survived many things that many don’t early on in life,” Juliette wrote in an Instagram post. “She fought for the voiceless fiercely. She understood suffering and the deepest pain. She had a presence everyone saw and felt. It is this presence that will continue. Out of the dark space in which her light got dimmed. I will remember her as tuff. Wise. Funny. Spiritual. And hopeful. This is another great reminder to call and check on someone when you think to. Not when its too late. RIPMistyUpham."

But it was her tweets that sent a much stronger message:
    "#RIPMistyUpham I am in shock and greif [sic]. I pray the police do a murder investigation. They're saying not "foul play" when of course it is ... Misty spoke out alot against injustices within Native community. And had known enemies. Police must do an investigation ... Misty told me about horrible violence she suffered on NA reservations She felt she coul be murdered! Bcuz she was vocal #ThisIsNOTaSUICIDE."

Our thoughts are with Misty's friends and family...
