The bullet case count for the bedroom cannot be correct.
Ralph cannot have been shot 4 times in the bedroom and not have left a trail of blood from there , all the way down the stairs and into the kitchen. 4 hits would have included 2 shots to his face/head so the chances of mobility by then would be very reduced.
It does not make sense .
In my view the 2 bullet cases that are claimed to be accountable to Sheila being shot are questionable .
As far as Ralph is concerned it seems he may have been shot while at the bottom of the stairs and in the kitchen only.
Bullet cases can be moved too easily to be relied on as giving safe evidence as to locations where shots were fired from. These bullet cases with no accompanying blood trail fall to be rejected as misleading and may be viewed as part of a cover up by a person or persons trying to mislead others.
