It actually looks like she's accused of shooting someone who'd been with her friend group that night

Doesn't make it right in the slightest, at least as far as I can tell

I'm firmly of the opinion that US prisons in particular are barbaric, inhumane institutions, though. As it stands, she's been held without bail awaiting trial for over half a year. I don't think that'd be appropriate, even if she was kept prisoner in safe and comfortable conditions.
