They're both monsters. If they've given this child to someone to keep it "safe" I don't trust their judgement. God only knows who that is, could someone pass a child off as their own and provide it with medical care, a nurturing environment etc without it being flagged? I don't think so. The type of people who hide children aren't good, they don't have good intentions.
If the child has died they've disposed of it.
If the child was in their care at the time of arrest they've left it alone, cold, dehydrated, starving, in distress, possibly open to the elements and easy prey for things like foxes.
None of those scenarios are good.
