It was first degree manslaughter- the article says she was facing “up to 25 years.” She threw a tantrum about being asked to leave a park that was closing, threw her dinner on her fiance, “stormed down the street” then saw a little (100lbs vs her 175) old lady across the street, crossed the street while calling her a bitch, then shoved her onto her head. I don’t think 9 years is too long for society to be protected from her.
The court ruled “not a murder” because it was just a shove, but anyone could have seen than a shove like that would likely kill a small 87 year old woman and it certainly wasn’t an accident. The woman wasn’t just in her way while she was angry walking down the street. She went out of her way to attack the woman.
Then there’s the part where she evaded police for weeks, hiding her phone at a separate location, changing locations multiple times. I don’t think the longer end of her sentencing options would have been unreasonable at all.
