"The blood content of an adult is equivalent to 8 percent of body weight, and the amount of blood that an adult man has to use continuously to wash after his body is mutilated."

Lu Yan continued, his voice was flat, "I just said that the murderer's cleaning is to hide his own bloodstains, and secondly, to take away the bone ballast that cannot be stirred, so that it is not noticeable, so it is inevitable that there will be bone ballast in the cleaning flow, which will be broken and stuck between the sewers, causing poor drainage, which will cause water accumulation in the bathroom and floor infiltration." The reason for this speculation is that the tenant of the same corpse mutilation in the bedroom, the eyewitness girl, had clearly stated that after living in the kitchen for three months, she had asked the landlord twice, and each time the reason was that the water was blocked and there was a problem with waterproofing......"

"Wang Ju, it's confirmed", the voice fell, and he saw that the personnel of the second team had already panted and ran over to report, "The room downstairs, the roof of the room, there are indeed traces of water stains penetrating, although it has become moldy and cannot be seen, but now there is still a strange fishy smell, after identification, it should be blood and water......

When the words fell, everyone looked at Lu Yan's expression, and they had a little more admiration-

Such subtle evidence and conversation can be noticed by experts, and applied to reasoning, and the conjecture is seamless...... An expert, a genius!

"And the probability of knocking on the door three times", Lu Yan slowed down his voice and stated plainly, "It is based on the experience of previous corpse shredding cases to speculate on the murderer's psychological activities and time progress, plus what Fang just said when he visited his neighbor, the last time he saw the deceased was when she went up and down the stairs at night and quarreled with others, then, it is not difficult to guess that night was the night when the murderer's corpse was broken, and it was also the night when the old man was tragically killed...... Night of the Revenant! “

As soon as the four words fell, everyone trembled, for that sense of reality!

But looking at Lu Yan, he still didn't have any feelings, his tone was flat, and he continued to state.

stated, belonging to the scene at that time, the most cruel truth———

"The murderer, open the door, knocked down the old man with one blow, and didn't give her a chance to make a sound."

Turning to the bedroom, Lu Yan's tone was calm, "After blocking his tongue, he dragged and came to the bedroom." ”

He moved to the door and stayed in the direction of the door frame, "At first, the murderer's killing intent was not strong, so the first blow didn't even leave a trace on the old man's body, but, as soon as he arrived at the door and saw the scene of the corpse, the old man showed fear and reacted more and more intensely. ”

He stopped, not moving.

Tang Xiaonian stepped forward as a foreshadowing, supported the back of his chair, walked forward, pushed him indoors, and heard him say again: "The murderer who has just completed the corpse mutilation, the endorphins in the brain have not completely declined, and after being stimulated from the outside world, the excitement is ignited again, and in order to achieve his own psychological satisfaction, he has begun, the first batch of abuse." ”

He turned around and signaled, Tang Xiaonian stopped, Lu Yanyan, and looked at the door frame, "At first, in front of the door, it was just a beating, this move, but because the old man struggled to resist and grabbed the door frame, he caused a fracture when he struggled." ”

His eyes went all the way in, "Then, pulled to the bedroom, the old man who had lost his mobility, facing the corpse crushing field, wanted to scream in fear, but because he was blocked by the murderer, the reaction was even stronger, and the murderer was more stimulated, in order to increase the visual feast, he picked up the fruit knife and began to stab. ”
