The bible is a rectangular and straight object making it ideal to set the grid. The primary refence points I am using is the creases and folds in the nightdress going along the rifle.
Sorry mate but you're undermining your claims as far as I can see.
One of three things happened, when the rifle was moved. Bear in mind that the drop earring sits partially exposed, within a bloodied fold of the nightdress.
1 A police officer has removed the drop earring.
2 The drop earring has moved and is now fully covered by the bloodied fold
3 The drop earring has become dislodged from her person and / or as a result of dislodgement, is no longer visible.
It's not brain surgery.
