Wu Rui suddenly asked, "Dongzi, have you ever killed someone?" ”

Xu Dong was stunned for a moment when asked, and after a moment of silence, he said, "Killed." ”

Wu Rui continued to ask, "How did you feel about killing someone for the first time?" ”

Xu Dong recalled: "I remember that I was very nervous, and when I watched the suspect fall to the ground, the cold sweat on my body came out, as if all the strength in my body had been drained, and it took me a long time to recover, and then I had nightmares for a long time." ”

In the process of recalling, Xu Dong's breathing became rapid due to nervousness, and he swallowed his saliva after speaking. Wu Rui knows that when people are nervous, they will feel that their throats are dry, and they will naturally swallow saliva.

Wu Rui said: "These are normal physiological and psychological reactions of yours, but the murderer does not seem to have any signs of such psychological and physiological reactions.

His entire criminal process is divided into three steps, two steps are required to kill the victim, and another step is to tie up the deceased's son, you know the allusion in one go, right? ”

"You know, all at once! Then decline, three and exhaustion, the director always likes to say this sentence when he directs the task. Xu Dong smiled.

Wu Rui knew that Xu Dong's smile was to relieve the emotional tension before, which was a kind of psychological self-regulation, maybe he didn't realize it himself.

Wu Rui continued: "The murderer's entire murder step is divided into three steps, and under normal circumstances, no matter how these three steps are combined, they will have a certain alleviating effect on the murderer's criminal psychology.

His killing rhythm will stop because of this, but I analyzed the trace rhythm of the crime scene, but I didn't find this, and I have that inference from the above. ”

"If that's true, it's not easy to check! Even if it is true, if the Tattered King does not admit it, and we do not find the body, there is no way to investigate. ”

Wu Rui suddenly smiled mysteriously: "If my guess is correct, the drunkard father of the Tattered King was really killed by him, I know where the body is buried?" ”

"You know all this?" Xu Dong asked in surprise: "If this is the case, where is the body buried?" ”

"It's buried in his house, or within 10 meters of the backyard, and I think it's most likely to be buried in the house." Wu Rui said in surprise.

"Why is it more likely to be buried in the house?" Xu Dong asked puzzled.

Wu Rui glanced at him and said, "You are stupid! If the assumption is true, the tattered king was only thirteen or fourteen years old at the time, and he was disabled and thin, and it was understood that his drunkard father was about 1.7 meters tall.

It is naturally not easy for him to kill him head-on, but his father is a heavy drinker, and when he is drunk, he can easily kill him, and after killing, he will naturally throw his body in order to cover up the crime.

With the physical condition of the Tattered King at that time, it was not easy to throw the corpse, and it was easy to be found, and the easiest and most effective way was to bury him nearby, because of the situation in his family, few people came to his house, so he had plenty of time to complete the burial. ”

"Oh, I see." Xu Dong only felt suddenly realized, thought about it along his train of thought, and said happily: "Naturally, the burial of the corpse should choose a place that will not be discovered, there is no one behind his house, the pit dug in the courtyard is easy to be seen, and few people go to his house, so the house and the back of the house are the most difficult places to be noticed." ”

"Bingo." Wu Rui snapped his fingers and said.

Xu Dong stopped and said, "Since that's the case, let's hurry up and report to Team Xue." ”

When Xu Dong called Xue Zhengnan, they were having dinner in a restaurant, and after listening to the report, Xue Zhengnan attached great importance to it, and immediately communicated with Hu Bo with the attitude of believing it rather than believing it.

Then Hu Bo decided to send an investigation team to excavate the scene, and he replied to Wu Rui and the others, Xue Zhengnan and others originally wanted to go, but because the case was in speculation, and it was possible that it was done by one person, Hu Bo used this to keep the members of the serious crime team in the county.

The excavation work at the scene did not need Wu Rui and the two, so the two did not return to the tattered Wang family, and the two came to the crime scene while talking, although the case was basically clear, but Hu Bo still left two policemen to guard the scene, Wu Rui said in his heart that the director of the county public security bureau is not a fool.

The weather in the Northeast in January has a huge temperature difference between morning and evening, especially in recent years, when there is less snow in winter, but it is exceptionally dry and cold.

The two policemen inevitably destroyed the scene, did not guard in the house, but locked the door and wore a thick coat to stay in the car outside, although the current public security system equipment has been improved, but sometimes the conditions for handling cases are still very difficult, especially the tasks such as squatting and tracking are not day or night.

The two policemen knew Wu Rui and the others, and when they saw them coming over and hurriedly got out of the car, they stepped forward and said enthusiastically: "Thank you two comrades." ”

"It's not hard, you're really hard!" Xu Dongzui said sweetly.

"It's all about work, not hard work." A policeman said honestly.

Wu Rui smiled: "That's right. ”

"Are you going back to the county? Still is? A police officer asked.

Wu Rui expressed his intention and said: "We want to go to the scene of the crime and take a look." ”

A policeman took out the key and took them to open the door, and said with admiration: "Your city's serious crime team is amazing, and the case was solved before you arrived at the scene, how did you find out that the murderer was the king of rags?" ”

"This is a bit complicated, it is inferred based on the psychological portrait of the suspect, but I didn't expect it to be him." Wu Rui said.

"Mental portraits?" Listening to his tone, this policeman was obviously a little unfamiliar with the word.

After the police opened the iron door, Xu Dong glanced at Wu Rui and said to the two policemen who were following him: "Just give us the key, you know the house of the Broken King, right?" ”

A policeman who had participated in the previous arrest operation, went to the house of the Rag King, and said, "I know. ”

Xu Dong said: "You two go to his house and guard outside!" After a while, the county will send a survey team to excavate the site. ”

The honest-looking policeman asked curiously: "Excavation site?" What's going on? Is it excavated there? ”

Another policeman also asked: "We have checked all the places and all the valuable clues have been brought back to the bureau, what else do we need to unearth?" ”

Wu Rui said solemnly: "It is possible to excavate a white bone. ”

"A white bone?" The two policemen immediately asked curiously.

Wu Rui said in his heart that these two people are so curious and exploratory, no wonder they will come to be a policeman, Wu Rui turned his head sideways and gave Xu Dong a look, Xu Dong knew that Wu Rui was most afraid of this kind of trouble, and when he was about to tell the two of them the general situation, the two looked at the direction of Wu Rui, who had entered the scene of the crime, and their expressions were full of respect.

Xu Dong sent the two into the room, only to see Wu Rui wandering around the bedroom of the East House where the crime occurred, wearing shoe covers on his feet.

Xu Dong also came to the scene of the crime for the first time, and found that the interior furnishings were very simple, just a bed and a wooden combination wardrobe, a group of sofas and several sets of heating, a computer desk under the window, on which computers and some small ornaments were placed, the windows were intact, and the floor was covered with common dark red wood grain floors.

The ground was clean, so the lines of the deceased's death drawn by the survey team with white lines and the five dark red blood stains were particularly glaring.

Xu Dong put on shoe covers and walked into the scene, looking at the photos of the scene and coming to the crime scene to see it with his own eyes, are two completely different sensory experiences, and the 3D picture is always more shocking than the 2D picture.

Xu Dong squatted down to check, and saw that the traces of death left by the deceased were very clear, and even the direction of the blood splash was not destroyed, and the protection of the scene was very complete and shocking.

"The scene of this crime is very well preserved, and it seems that the teacher who found the scene is still very knowledgeable! He has the potential to be a criminal policeman. ”

Xu Dong still carries forward the optimistic character of being able to do everything, in order to relieve the discomfort in his heart, he picked up a crystal ball on the computer desk and played with it, he has been a police officer for four or five years, but he is still not very used to these bloody pictures.

"Yes! Thanks to that teacher's awareness of protecting the scene, you must know that there are many cases, and it is because the scene is not well protected that there are many detours in the process of solving the case. Wu Rui looked at the messy bed and said thoughtfully.

At this time, the door opened, and the two of them were shocked and touched the pistol in their arms, knowing that some perverted killers would return to the scene of the crime after killing people, and after a while, the two breathed a sigh of relief, it was they who were too worried.

It turned out that the honest-looking policeman from before went and returned, and he came to the door with a plastic bag of things in his hand, and said embarrassedly: "This is the food that Comrade Xiao Zhang asked people to bring to you, and I forgot to give it to you in a hurry before leaving, I'm sorry." ”

Xu Dong let go of the hand holding the gun and said with a smile: "What's polite." As he spoke, he carefully bypassed the marks on the ground, walked to the door and took the plastic bag in the hands of the police.

The two said a few words, and the police looked into the house a few times, nodded and said hello to Wu Rui before leaving.

Xu Dong lifted the plastic bag in his hand and looked at it: "There are bread, ham sausages, roast chicken, and drinks." I still hope to be considerate and know how to take care of people. ”

Wu Rui looked at him and smiled playfully: "You don't really like Zhang Panpan, right?" ”

Xu Dong smiled a little embarrassedly: "You can see this?" I really can't hide anything from you studying psychology. ”

"It has nothing to do with understanding psychology or not." Wu Rui smiled evilly: "It is a person who can smell the strong, male hormonal breath exuded from your body." Oh yes, your situation is called estrus in layman's terms. ”

Xu Dong picked up the things in his hand and was about to throw them over, scaring Wu Rui and then putting them down, he asked embarrassedly: "Seriously, little Angs, do you think I have a chance?" ”

"I majored in psychological criminology in college, not love counseling." Wu Rui spread his hands and made a helpless gesture: "It's useless for you to ask me, but I know that if you don't chase it, you will definitely have no chance." ”

"But... I'm just an ordinary criminal policeman, but I'm a high-profile and beautiful student from a prestigious university, can she take a fancy to me? ”

Xu Dong used a question sentence, it seems that he really has no bottom in his heart.
