When I think about it,even the " proper ?" pic of Sheila is far too clean to be true,as I have to wonder after killing those people,why she isn't literally up to her eyes in blood which would have catapulted off those who she'd killed. The splashes from wounds at such close quarters would have rendered her looking like June. ? It's not unusual for the shooter to have ended up being as splattered as the rest.
Then again,it IS believed that Sheila was in a mess once at the mortuary.
