I've just been reading online about poor Hakeem. I think that it's probably not attracted as much press outside the local area because (not that this makes it any better, she was still a terrible parent) it sounds more like his mum appallingly neglected him, causing his death hence the manslaughter charge, rather than murdering him as in the case of Arthur and the other poor little children like Star and Logan.
(I hope that doesn't sound like I'm defending her in any way, that's not how it's meant).
It seem Hakeem's mum wasn't even charged until last year, 4 years after he died. I can't understand why it took so long though? I know cases often take a long time from being charged to the trial actually taking place, but 4 years to just be charged seems a really long time.
