Yet another case of a young teenager finally getting back at his sperm donor for years of abuse. I'm not going to cry for the daddy. He should have spent more time loving his son and less time traumatizing him and beating the hell out of him. If the boy hadn't killed the dad, then the dad would have probably ended up killing the boy or someone else.
Wow, what rage this kid has. Definitely sounds like an insanity plea is appropriate.
