I'm really hoping the baby is ok.
Imo, if the baby is alive and with someone, I don't see them telling anyone where it is until they are sentenced and that's only if it is a very long time when it's clear they may never get to be in their child's life. Even then, they may not tell anyone because having the chance of letters, perhaps visits later on will be better than nothing to them.
Otherwise, I'm really saddened to think that the baby didn't make it. They had a pram (a buggy type for an older toddler maybe) shortly after going missing whilst in Whitechapel I believe and disposed of it quite soon after when going to get a taxi. I'd wondered why because a taxi will usually have room for a buggy.
DH pointed out earlier there are so many questions and uncertainties unless they were wanted for something else prior, it seems really muddy water for a conviction. The manslaughter charge must be to try and get them to tell them everything.
Re getting no medical assistance, I read very early on that they called for an ambulance initially but gave up. I can't find it anywhere but that was not mentioned much again. Did anyone else read this?
