So did the search go something like this ...
PC responsible for searching, finds a chair, stands on chair and removes hatch. Sticks his head through the opening and shines a torch (flashlight) around the loft area, doesn't see anything worth looking in to, so replaces the hatch and calls it a day.
I don't see how it could be otherwise, as it wasn't until they actually decided to get a ladder and do a proper search, that they found the body. It looks like laziness and incompetence played a big part in this. That's just like opening a door to each room without actually going inside, just eyeballing the place and deciding that she is not there.
