You doing alot of rambling. No one here has an obligation to this kid, that's the local government of where he's from (Milwaukee's) job, since apparently the family, whether voluntary or nor, failed their obligation to him...
There needs to be extensive screening on this kid's mental state, which shouldn't be rushed. This also means the deepest dive into what home was really like, the influences and adults who were around him, all of that. At the same time he should still be educated---->he's 10. Locking him up in a regular juvie, with downright mediocre rehabilitation and education prospects, would be "insane". With kids older and bigger and more mature and developed than him, how would this make sense?
Put him in a crazy house throughout the entire process it takes to determine his mental capacity, while limiting (not eliminating) his interaction with others, and assigning tutors or age-appropriate instruction with him several times a week...
Monitor his entire progress but under no circumstances should he be jailed beyond 21, that's 11 years there. If there is significant progress in his mental state, his behavior, his ability to learn at age level, let him out between 15 to 18, that's 5 to 8 years put away, and release him to state custody (halfway houses and shyt like that) if the family doesn't want him, and then he has to abide by all the rules and structures parolees have to...
I wouldn't transition him into a regular juvie until he's 15, if I have to...
So you're locking him up a minimum of 5, maximum of 11 years, getting him extensive therapy, testing, counseling, while also providing age-level education services. If he reoffends, it's over, and it would be made clear to him that a kid who murdered his mother can't do anything wrong again or the full extent of the law applies to him...
I don't think anyone under 18 deserves adult penalties, but it's unconscionable to me to me that yall think a 10-year old does...
Locking him up and throwing away the key is not the fix...
If he was my close kin (brother, son, cousin), I wouldn't want him with me anytime soon, but I'd have the same suggestions I had earlier, and I'd want to maintain a semblance of contact (periodical letters or visits) t9 check on his development with my own eyes. Kids have to know they are loved and cared for, if his family washes their hands with him they are further contributing to his delinquency...
Maybe they can be, but I wouldn't put this on him without doing the work first. No one is born bad...
That turn the other cheek shyt doesn't start with the law, it started at home. The amount of passes he got for his behavior at home is probably numerous, we know that many of US don't do the work required for children who need more accountable parenting. Lifetime custody wouldn't help shyt with this boy...
