"What a ruthless murderer...... Jiang Kai swore that he had never seen such a bloody scene.

In the living room of the room, a tall and thin man lay sideways, his snow-white shirt was stained black and red with blood stains one by one, and the flowers spread and shaped in irregular shapes, and the number was so large that it was conceivable that the murderer was crazy and irregular in his attack on him. Face up, upper body slightly tilted to the left, dead and blind. The pupil focus in his eyes was completely dilapidated and he was not angry at all. On the left-hand side is a bunch of keys, which are quietly parked there.

For a while, Jiang Kaisheng felt shuddered, and there was a chill behind him. And Rogier had already put on gloves and stepped forward to conduct an autopsy, explaining the situation while examining: "The body was about five meters away from the door, and the victim died on the floor, with extremely deep wounds and flat and small wounds. The murder weapon is suspected to be a dagger or something, and on the left and right sides of the corpse are bookshelves that have been turned over, and there are no books in them, they are empty cabinets. Not far from the victim, there was a transparent fiberglass coffee table and several neat plastic chairs. The glass door from the living room to the balcony was locked, and his wife, who found the victim, said that the door was also locked, but the key was in his hand. There was very little blood on the ground, so it was not supposed to be an indoor murder. So why did the killer deliberately make the scene look like a fight? And what is the murderer's motive for killing? ”

Rogier said while inspecting the scene, his glasses reflected the miserable Xiao Li, and he said, "And it's been two days since I died." ”

"Dead for two days? Posthumous stiffness lifted? I studied it when I was in the police academy. Jiang Kai thought for a moment.

"That's right. Generally speaking, when a person dies, it is in a state of relaxation at first. Two to three hours after death, the stiffness begins to become stiff, six to eight hours the stiffness pervades the whole body, the peak value is reached in twelve hours, and then it begins to soften, and in one to two days the stiffness is completely relieved, which is what the victim is in now. Rogier said feverishly with his glasses on top, and then said, "The murderer is very cunning. ”

"Report to Director Jiang! The on-site investigation team has done fingerprints on the room and found no fingerprints, but has taken notes of the surrounding neighbors. Li Xingxing handed the notebook to Jiang Kai, who scratched his head and flipped through it as if he hadn't found any useful clues. Rogier went to the gate and crouched down, took out a magnifying glass and looked for something on the ground around him, and suddenly he squatted down, stroked a slender white mark on the concrete floor with his gloves, and measured the gap under the wooden door with his fingers, and then his eyes gathered on the face of the deceased, as if he understood something.

"Huh? How is this possible? Jiang Kai suddenly pointed at a passage on the transcript and questioned, he read: "Last night, when I came home from work, I saw that the lights in Officer Li's house were not on, and I felt strange, usually he would turn on the lights in his room at this time. Maybe I was working overtime or going for a nightlife, but I heard a strange loud noise that was "Bang! "It came from his room and startled me, it must have been a hallucination or a haunting, right?"

"Li Xingxing! Hurry up and arrest this person for me and interrogate him properly. ”

"Wait." Rogier stretched out his hand to stop him, then said with a sneer: "This person is telling the truth, which happens to be in line with my reasoning. The "murderer" is in the mouth of the deceased.

"Huh?! You're talking nonsense, aren't you? I don't feel comfortable with this nonsense! Li Xingxing hurry up and take a look! Jiang Kai exclaimed, looked at the deceased, and saw that the deceased's cheeks were a little bulging, there should be something inside.

Li Xingxing put on gloves and stepped forward to play with the deceased's jaw, but it was surprisingly tight, he rolled up his sleeves, and made a lot of effort, his face was red, and finally "clicked" with a dislocated bone. In the deceased's mouth, Li Xingxing then used tweezers to take out a dry yellow-white cigarette butt. The cigarette end is white and the cigarette is yellowed by the nicotine in the tobacco because of the saliva.

"I think this cigarette butt is familiar." Rogier asked, then took off his gloves and said, "It was the same person who killed the deputy county magistrate, thanks to his wit before he died." I'm going to show you the murderer's modus operandi now, and you can interrupt me at any time if you have any questions. ”
