A team of doctors had examined the bodies and had concluded that none of the Riddles had been poisoned, stabbed, shot, strangled, suffocated, or (as far as they could tell) harmed at all. In fact (the report continued, in a tone of unmistakable bewilderment), the Riddles all appeared to be in perfect health -- apart from the fact that they were all dead. The doctors did note (as though determined to find something wrong with the bodies) that each of the Riddles had a look of terror upon his or her face -- but as the frustrated police said, whoever heard of three people being frightened to death?
