There loft is partly seperated i read.
I think the washing powder is totally irrelevant, if they were trying to wash away evidence forensic would notice that parts of the house or certain unusual things had been recently scrubbed and that would become suspicious, maybe the gran was expecting to have to stay away from her home and needed to wash her clothes if i had to leave my home I think one of the few things id take is washing powder to clean your clothes, they wouldn't of had Tias clothes to wash as shed still be wearing them or police would of found them. It's a very strange case.
