I'd guess with close family members - either on Mother's or dad's side. I'm unaware if they might have aunts and uncles, but if not with dad, then think maybe with close relatives if able/willing to take them in. MooThank you. I didn’t go back to check.
I think this is even more confusing wording. I’ve definitely heard those words used to describe children being taken into care. In this case I still think it probably quite literally means removed from the house, which is a crime scene.
I think they’re probably with family. I hope the media don’t go looking for them or bothering them.
