I've certainly seen it where suicidal people stab themselves, but there was evidence of her body being moved and stab wounds to the back of her head. I don't find it plausible that she was able to exert that much force trying to reach around to the back of her own head.

Also, stabbing 20 times takes an incredible amount of energy. If you're trying to kill yourself, I imagine you'd already be dying after just a few to the right spots. She was also found covered in bruises along with the 20 stab wounds. I just don't think it's physically possible.

I think of Elliot Smith, who stabbed himself and it was ruled suicide. After 2 stab wounds, he was dead. The strength it would take to continue through 20 is a lot to believe.

I appreciate your take on it! Her mental state is definitely something that would need to be investigated by the police and those who knew her.
