While unfortunately this is probably the case, I wouldn't be so quick to judge the parents. I know a few 12-14 year olds who are very bad and manipulative kids. The one in particular that comes to mind, is very good with mind games, and can expertly point the blame on anyone for his reasons of acting out, he also can lie better than a fisherman. His parents are good people with a problem child. Parents just don't cause all mental illness/problems. Some are actually caused by other factors. 13 year olds are pretty smart, and they learn a lot in school about child abuse, domestic violence etc. There is a good possibility he ate the dessert, the little brother was going to tell on him, and he beat the tar (death) out of him. Hopefully an autopsy was done, and the contents of his stomach checked. I think this kid knew he could put a spin on this to make his parents look like they where the bad ones.
