The report quotes the mother -- not exactly and impartial source either -- saying that the father deserted her. The old, "I'm a victim, too" excuse.
You have now filtered something through two biased sources.
What do you actually *know*?
That the mother was responsible for the child, he was filthy and he hung himself, and that's all you know.
If you want to rant about the father, long absent for whatever reason, feel free, but don't expect anyone to take you or the mother seriously.
The boy is dead because of the mother. Period.
