Most likely, a 10-year-old would not be incarcerated.
The only reasons I can think of that this might not be the case is if the parents requested she be locked up, or an evil, corrupt judge, or a good judge needed some reason to quickly separate the child from the parents and used the hearing as an opportunity to do that.
Yeah, I read that. It's the 10-year-old part of it that I'm having trouble with.
If she was 15, yeah, no problem, 6 months in juvie.
13 with priors, maybe 30-90 days.
10 years old? There's going to have to be some sort of special circumstances to justify incarceration. The severity of the crime isn't going to do it.
You're going to have to show that she should be treated as a much older teenager, or that the judge is excessively, abusively harsh.
