You know, he is so large, that management of him in juvenile detention is going to be significantly different from other kids, especially due to his charges, Capital Murder, killing a child under age 16 by abuse or torture. I don't know if he has actually been charged yet, but that would be pretty close.
He will be in solitary confinement and lockdown. He would just be too risky to be allowed any movement with other detainees. If I was doing his risk assessment, he is definitely a 10. High risk of violence, and risk to staff.
Due to that, any time he would be transferred or transported anywhere, it is going to be full shackles. That kid is really going to have a reality check on his new life. Guards, even in juvenile, are not the most sympathetic people, for good reason, that way they don't get manipulated, however, their demeanor isn't the friendliest. Good.
