"The hostess was grabbed from bed by the murderer and had her carotid artery cut in front of their wedding photo, so her blood splattered onto the photo. ”

It was not Ling Qingyan who answered Li He's question, but Chai Jun, a forensic doctor who walked in with Zhao Yong. This rookie forensic doctor, who looked thin and small, and thought he was a student when he was not paying attention, said: "I was also fortunate to participate in the special case discussion of the forensic team this morning, and the forensic doctor Chen, who presided over the case, put forward this inference I just mentioned based on the blood splatters, the restraint injuries on the female deceased's body, and the sorting and restoration of the items on the bed by the trace examination. ”

Ling Qingyan said: "This is an extra move, even if the female deceased has already discovered the murderer when the male deceased is killed, it is still easy for the murderer to kill her in bed." Or if the female deceased had fled, and the murderer followed her and killed her, the location should not be on the bed, and there is no reason why the blood would splash on the wall. What is this concept? In addition to committing murder, the murderer also behaves very abnormally?"

Li He looked at Zhao Yong and smiled, and said, "Brother Yong, come, let's simulate it." ”

Zhao Yong leaned in and expressed his resolute opposition, but Ling Qingyan took the initiative to say, I'll come, I'll play the female deceased. The reenactment of the case is an important auxiliary link in the detective reasoning.

Of course, Ling Qingyan would not lie on that bed, they changed to the small living room outside the master bedroom, Zhao Yong lay on the ground and made a throat cut, while Ling Qingyan lay on the ground and made a discovery, poking up his upper body. At this time, Li He rushed forward with a stride, grabbed her collar, and first threw her to the ground (of course, the last force was left), which was enough to make her temporarily in a state of confusion, and then Li He turned her body over, it was she face down, covered her mouth and pulled her body up to stand on the bed, at this time Ling Qingyan struggled fiercely, but her chin was lifted up strongly, and then the murderer let her stand and cut her carotid artery.

"Yes," Chai Jun said: "The scene is likely to be like this, the female deceased still has a knife wound on her arm, it is likely that the murderer tried to block her carotid artery when she tried to block it, but the murderer was quite professional, and the murder weapon used was very sharp, so that all the struggles of the female deceased were in vain." According to the photos taken at the scene, the male deceased died in a deep sleep, with almost no facial expression, while the female deceased's facial muscles were distorted and her pupils were violently dilated.

Ling Qingyan covered his neck with his hands, and was stunned for a moment before saying, "Extreme fear and despair." ”

Zhao Yong said: "In such a comparison, the male deceased is considered happy." But why did the murderer do this?"

"Because the female deceased discovered him, which aroused his tyrannical psychology and distorted his psychology in an instant, it is likely that he would get more pleasure by killing the female deceased in this way, which is enough to show that he is a habitual offender," Li Hyuk concluded. ”

Ling Qingyan turned his head to look at him and asked, "Is that what you call a professional killer?"

Li He spread his hands and said, "Okay, I take back what I said before, maybe this is not a profession, but all indications indicate that he does not commit a crime once in a while." He should not have committed murder as soon as he entered, but entered the house late at night and lurked for a period of time, until the master fell asleep in the middle of the night. And then his murder weapon was professional......"

Chai Jun added: "It should be a scalpel, the wound of the deceased is very thin, but the incision is extremely deep, and if it is a thick-bladed murder weapon, the wound left will be very open." ”

Li He said: "And fierce, calm. After the hostess was killed, he did not immediately go downstairs to kill the old man, but waited at the top of the stairs, and when the old man heard the hostess's screams and went upstairs to ask, he killed the old man on the stairs, because he was a latent attack, and the old man was put down without any reaction at all. He didn't even let the old man roll down, but hugged the old man from behind and let her slowly spread it to the end of the stairs, so just now we saw that there was a lot of blood at the top of the stairs. ”

Chai Jun said in disbelief: "Oh my God, you seem to have seen it with your own eyes." ”

"It's just speculation," Li He said. ”

Chai Jun said: "This is very similar to my master's inference, but my master is an experienced old forensic doctor, who are you sacred?"

Li He did not answer her question, and continued: "The old man was killed in his room, but he was awake at that time, and he wanted to go with his wife to see what was going on, but he probably didn't think it was appropriate, so he stayed in the room, but the door was not closed, and the murderer followed and pushed the door in and killed him, so he fell under the bed near the door." As for the child, he was also killed in a deep sleep, and the child's sleep level was relatively deep, and he should have no idea what was going on at home, so until he left this world, he was still asleep in his own small bed. ”

Ling Qingyan gritted his teeth and said, "The murderer is ruthless, cruel, psychologically distorted, and has a lot of blood debts!"

Zhao Yong thought for a moment and said: "But none of these characteristics can be used, this city is so big, there are millions of people living in it, and a large part of them are floating population, can you tell who is such a ruthless murderer?"

Li He said with a serious expression: "There has never been a so-called perfect crime, no matter how clever a criminal is, he will leave clues." At the very least, we can know that the murderer is not tall, but he is skilled in killing methods, has excellent psychological quality, and is cold-blooded and cruel, such a person does not exist in ordinary citizens. There are all possible police personnel, forensic doctors, retired soldiers, strong thugs involved in gangs, etc., although the scope is still very large, but it has been narrowed down a lot. Combining these groups of people, and then continuing to investigate the interpersonal relationships of the deceased, there is always a direction. As for the extent to which it can be found in the limited time, that is a matter for the Force. ”

Ling Qingyan glanced at Li He, Li He helplessly spread his hands and said: "Sister, I have this ability, even if my father is here, he can only make similar inferences based on these clues, if you are not satisfied, I have no choice." ”

"Okay," Ling Qingyan said, "Collect the team, let's stop here today." I'll go back and sort out these clues, and try to talk to Team Gu. Everyone has worked hard, after going out for a while, Zhao Yong sent Xiaochai home, and Li He accompanied me for another walk. ”

"Still leaving?" Li He looked at his watch, it was two o'clock in the morning, he didn't say anything in front of Chai Jun, but he wanted to say to Ling Qingyan, sister, I still have class tomorrow...... Okay, I can skip class, but the question is, can't you solve the case and toss yourself so sleeplessly?

Coming out of the Senna Sunshine Community, Zhao Yong sent Chai Jun to leave first, and Ling Qingyan pulled Li He to continue walking aimlessly on the streets in the middle of the night. It was really pulling, and her hand was tightly gripping his. Li He felt that her hands were trembling a little, so he stopped, turned her body to face him, and said, "You are a policeman, and it is your duty to catch the murderer, but you are not a superman, and you can't solve all the crimes." Whether it's out of anger or self-blame, I want you to be clear that these emotions don't help you analyze the case. If you want to be a good criminal policeman, staying calm is the most basic condition. Well, that's what my dad said. ”

Ling Qingyan lowered his head and didn't speak, Li He simply didn't say anything, and reached out to hold her in his arms. Ling Qingyan didn't struggle, and of course he didn't cooperate with him, and after a while, Li He felt that there was no sense of accomplishment in hugging her like this, so he could only let go of her helplessly, and said, "Okay, go home and sleep, and discuss with your boss tomorrow." Even if the murderer can't be found, the person who bought the murderer may have clues, one is the most contradictory, the other is the most vested interest, and the murderer has a strong psychological quality, which does not mean that these people also have it. ”

Ling Qingyan raised his head violently and said, "Yes, we are all accustomed to staring at the murderer, in fact, there is no one who buys the murderer, how can there be such a perverted murderer?" But after a burst of excitement, he said: "I can only find someone to investigate, after all, the murderer has not made a breakthrough here, and it is impossible for the person who bought the murderer to confess, and even if the murderer is caught, as long as the evidence is insufficient, others can die and not admit it." But no matter what, you've been with me until now, and you've helped me analyze so much, maybe it's a bystander, I can't see a lot of things. I promised you, and I did what I said. ”

Completely unexpected by Li He, the young lady seemed to have mustered up enough courage, just stood at a distance of only 0.01 cm from Li He, raised her head slightly and closed her eyes. Li He was stunned for a moment, and then there was a burst of ecstasy, no matter what the young lady thought, if she had to let go of such an opportunity, she was still not a man? So he also unceremoniously stretched out his hand and first supported Ling Qingyan's waist, only to feel that her waist was as hard as an iron plate, as for being nervous to this extent?

However, just when Li He was about to kiss first, Ling Qingyan suddenly opened his eyes, and as soon as he pushed his hand on Li He's chest, he took two steps back and said, "I suddenly remembered one thing, among these cases, the one that is closest to solving it is the one that happened in Faith City, do you think my master will have a clue?"

I'll go, Li He didn't even care about his father at this time, so he pulled Ling Qingyan over, put one hand around her waist, and the other hand around her head, and kissed her fiercely first. Yes, yes, the young lady's lips are really soft, and she won't be asleep.

But it can only be regarded as a kiss, not a kiss, because the young lady gritted her teeth and did not cooperate with him, if it had to be a kiss, it would be a strong kiss. Even if he kissed Li He, he didn't plan to give up, but there were two cars passing by them, not only passing, but also stopping and retreating.

Nima is going to make trouble again, Li He sighed in his heart, put his lips to Ling Qingyan's ear and asked, "Do you want to fight or run?"
