Do you mean like Shannan's jacket appearing in Brewer's driveway, or Shannan's sister finding her earring near his Steps? how about her belongings being found in the shrubs or her remains being found a year after her disappearance? give me a break. you know better. evidence can be there - right in front of your God damn nose and be missed. it happens to the best of them.
We allready know she was running around. If she was running around she would have been dropping things. Finding things she dropped is evidence that she was running around.
But we allready knew that.
She went to Brewers house on an outcall. Finding things near Brewers house is evidence that she was at Brewers house. Which we allready knew, because that is where she went.
This surprises anyone, how?
Finding her body and other items pretty much in straight line from where she was documented as moving along is evidence that she continued moving on that straight line.
Basically, we are finding exactly the sorts of things we would have expected to find.
