If Lee Bowers was watching the back of the picket fence where he said there were two men, and Sam Holland ran immediately around after the shots were fired and saw no one at the picket fence, then which one is telling the truth? Bowers or Holland?
Furthermore if the assassin (or assassins) went into the trunk of a car after firing the shots, as Holland suggests is a possibility, then why didn't Bowers see a man or men getting into a trunk of a car?
