blue25 - you say, 'one of them was at home.' That answers a question for me. I couldn't understand how this young couple had got into the house of the victims and no-one had reported them missing.I guess one of them lived with the victims and that is why they could watch TV, take a bath etc., after the crime.
TriciaF - Yes, I remember the harrowing tale of Mary Bell and I still have the report that was produced afterwards. It describes how she had visited the victim's mother more than once to express sympathy for her loss. I was a young social worker at the time and we were encouraged to read it. Mary went on to lead an acceptable life in adulthood.
Let us hope that there will be a future for these 2 children too although they will likely have to change their identities.
