Looking again at the pictures of Zahra's bedroom, a few things come to mind:
1). The pieces of drywall removed appear to be relatively low to the floor. Which makes me wonder if death occured on the floor of the bedroom, rather than on the bed.
2). The curtain that was on window by hole in drywall, has been been removed. Search warrants do not list curtains retrieved, but they do mention "cloth material".
3). It appears, near the other window, that a small piece of drywall was also removed. Either that, or it's a hole in the wall created by someone other than LE.
