This article is mostly about the family problems but at the bottom it says there were two council bin collections from the horseshoe area on the Monday morning, before Corrie was reported missing. These lorries don't record the weight of the collections. Seeing as the collection on the Saturday morning was 11kg, Corrie can't have been in that load, but it remains an open question as to whether he could have been in one of those Monday morning collections.
I don't know if they are two separate collections by two lorries or by one lorry. I'm just paraphrasing the bit of the article that stood out to me as relevant to the current discussion.
The family side of the article is very sad. The only important thing to me is that Corrie loves them and they love him, the rest of it is their private business and isn't relevant to the case. I hope they will work things out, though. It adds insult to injury for a family to have a major breakdown at a time like this, though it happens in many families, I believe.
