Poor poor boy! What a dreadful short life he must have endured at the hands of his so called parents (albeit the male was his mums partner, and not his biological father).
I hope they get life, and made to serve life! Ideally in squaller like conditions, but that's unlikely with British prisons.
Here's hoping in mates get wind of what they done and give them a proper prison treatment.
I don't condone violence but when people commit crimes of this nature, especially towards such a young, fragile, vulnerable child, they deserve all they get when behind bars!
