If you're familiar with the phrase "throw the book at," it refers to a maximum severity punishment: https://www.merriam-webster.com/dictionary/throw%20the%20boo...

Citing a random source for CA vehicular manslaughter law, it looks like you can get up to six years: https://www.kannlawoffice.com/california-penal-code-section-...

So, like, a six year prison sentence? Maybe more for multiple counts here? At least revocation of driving privileges forever (she's not getting any younger)? None of that happened.
