No, and that is because Sheila did not die inside whf until after 9am, that morning...
The smell of death is associated with putrefaction which is the scientific term for bacteria from the digestive system devouring the body. This doesn't happen right away. It is not likely that any of the bodies smelled.
After corpses sit a couple of days then they begin to smell and that is why people often discover bodies after several days not right away.
