” I assume the Arkansas kid didn’t burn down the youth jail and then rob someone and then shoot at police. .”
As to his age when he died, he may have been in his early 30s. The shooting occurred in 1998 and he would have been say 12-14 at the time. Five were killed.
I gather he stayed out of trouble after getting out.
The girl had to have been in trouble several times before going to the youth center and then several time after. Her future odds of staying out of trouble are not very good.
