Do we know if they are looking for her shoe or his shoes?
See the brown shoe and flipflop in post #515.
They were also looking for the white shoe in McFayden's room:

I'm not sure. I assumed it was her white shoe. It has been listed on the previous two search warrants as items to be seized. I didn't see it listed on the inventory of items actually seized.
