Well if they are totally innocent, they also must have had the world's worst luck-standing up there (with a mop) when postal police arrive and the dead body is inside. I still don't buy the mop story. Who waits until the next day to mop up a spill? And then goes to borrow a mop from another house? If they truly did not have a mop at RS why not use a towel or something else to mop it up?
