Chapter 9 A Ghost on The Road (II)(3)

 “You mean, a veteran armed policeman robbed with a rubber truncheon?” The captain also began his speculation. “When he met the victim on the road, he stunned the victim with the rubber truncheon and took the money from his pocket?”
 “No.” Master shook his head and resumed his firm expression. “First, if it is a road robbery, there is no need to rummage in his wallet on the road, take the money instead of wallet, just take the wallet is Okay? Secondly, I think the victim was attacked indoors, not outdoors.”

 “What? Can you see it indoors?” The captain’s eyes on Master have changed from eye-level to head up view.
 “Yes. Just now I mentioned that there was obvious bleeding in both knees of the corpse. Such bleeding is caused by squeezing and rubbing between the patella and hard objects.” Master said, “What is the situation in which patella and hard objects are squeezed and rubbed?”
 “On bended knees.”
 “Since there is a kneeling process, it must certainly not be on the road. Moreover, there is no scratches on the patellar epidermis and the pants of the corresponding parts, which indicates that the ground on which he kneels should be very smooth, such as floor tiles, marble, at least certainly not asphalt road.”
