I respect that you believe they are injuries however, why didn't Vanezis refer to them in his original notes? His notes were written before any conspiracy grew legs. He mentioned the old cut on her abdomen - why would he mention that and not the 'lacerations' on her arm?
She had blood on her palm which made the print on the bible the trails on her arm lead from her palm to form the trails and the dark spots are just where the blood trail came to an end the the blood thickened and dried.
How do we know all of his notes survived?
You were right when you originally posted that 'lacerations' was an exaggerated term for these wounds.
If /when you see clearer images - you will see that the trails are fainter / less viscous than the spots.
