just a quick note - I know now why I thought Anne had taken the clothes home . When she talks about what the police asked her to say in court in 1991 statement there is also a page where it says she did eventually take the bins home - she does not say the clothes were in them - but I knew I had the "impression" she took them home from somewhere. Probably not important , but you never know 
She noted in her trial testimony the garbage was thrown away and no longer existed as of the time fo the trial. So the dirty kid's clothing and bloody panties were at a garbage dump.
However, in her COLP testimony she mentions that to that day she still had some of the clothes she took from the bedrooms that she thought could have been relevant. So she still had some of the clothes at that point.
Whether she got rid of them between then and now we don't know and the only way to know would be ot ask her.
