If Bamber had been the killer, why would the prosecution and the police try to hide and conceal the bloodied finger and hand marks that were present at seven key locations, (1) the front lower part of Sheila's nightdress, (2) on the bible, (3) on the edge of the kitchen worktop near the ammunition and the telephone, (4) upon one of the 30 live rounds in the kitchen, (5) upon an empty cartridge box found in the gun cupboard, (6) upon the throat of June Bamber, and (7) on the top part of Sheila's right hand?
