Criminal Investigation Notes

At ten o'clock in the morning, in the large conference room of Nancheng City Bureau, Song Wen brought Lu Siyu and Fu Linjiang to the meeting. Tian Ming and Zhang Ziqi of the second team sat opposite them, Lin Xiuran and Xu Yao sat beside them, Gu Ju personally Presiding over the meeting is enough to show the importance attached to this case.

What made Song Wen a little surprised today was that there was a new face sitting beside Gu Ju.He turned his head to look at Tian Ming with some doubts. Tian Ming obviously didn't recognize him, and put his right index finger at him, and then spread his hands to show that he knew nothing.

The man looked about thirty-five or sixteen years old. He was wearing glasses, and his hair was a little self-curling. He looked gentle. Seeing that he was a bit familiar, Song Wen couldn't help but look at him a few more times.

Gu Ju saw that everyone was looking at the man, coughing and introducing: "Because this case is special, I invited Mr. Zhuang Yizhuang, a criminal psychology professor who recently recorded a show here, to help us analyze the case together and take a look. Can you have more clues."

The man named Zhuang Yi was humbled: "I am an ordinary researcher, and I will discuss and study with you here."

Song Wen finally remembered why that person looked familiar. Zhuang Yi was different from Zhou Yining, an expert who only assessed the psychology of police officers. He studied criminal psychology and was said to be good at analyzing the behavior of criminals.

In recent years, Zhuang Yi has also appeared on many legal programs and is a frequent guest of several variety shows.Song Wen has also watched some of those programs. This teacher Zhuang always throws out amazing opinions every time, and his words are not amazing. The analysis sounds shocking at first, but when you think about it, it makes sense.His eloquence is good, he has an obvious personal style, and he has a lot of fans on the Internet.

However, Zhuang Yi’s style has aroused opposition from some old scholars. Those old experts believe that Zhuang Yi’s psychological foundation is not solid, and many of his speeches are thrown out just for grandstanding, inferring that he is a clown who is subservient to the current media. Applied to actual case solving.

Some people even pointed out that Zhuang Yi’s academic qualifications are false, and the host is his trust in the analysis of the TV station. Many of the surprising analyses are actually the effects of the program, and some opinions are based on foreign programs. , Copied from the paper.

However, Zhuang Yi is still very popular. This time he came to Nancheng to participate in the new law science program on Nancheng TV Tower.Just as there was a serial murder case happening here, Gu Ju was unable to do anything, so he invited this expert to see if he could help the case.

At the beginning of the meeting, Lin Xiuran and Xu Yao showed various evidences and autopsy results on the scene of the third victim. Just like the previous two cases, the victims strangled to death.

At the end of the introduction, Lin Xiuran concluded: “We have now collected the murderer’s fingerprints, as well as semen and DNA, which have been compared with the existing database, and the identity of the suspect has not been confirmed.”

The comparison with the existing database has no result, indicating that the suspect has no criminal record and the fingerprint has not been entered into the system.

In theory, if you have a criminal record, you should be able to find information in the database. However, our country is sparsely populated, has a complex structure, and has high mobility. Therefore, the correctness of this database can only be used as a reference. .

"I think the murderer in this case has a certain tendency to violence. He may be a habitual offender. Although we did not find it in the database, you should not take it lightly. Some civil lawsuits, such as non-criminal referees, should be investigated. Just a moment." Gu Ju turned his head and asked, "Tian Ming, your team has been pursuing this case for a few months. Let me introduce you to these three cases."

Tian Ming nodded and made a gesture to Zhang Ziqi, the deputy team of his team. Zhang Ziqi projected the pictures and information of several victims on the projection.

Suddenly, scenes of several victims being killed appeared on the projector one after another. They were all female corpses. The scene was not bloody enough, but shocking enough.

"The first victim, Li Ling, thirty-eight years old...The second victim, Zhang Yajie, twenty-seven years old...The third victim was killed this morning and has just been identified. His name is Wang Xiaopei, 22 years old. ..."

Tian Ming introduced the situation of several victims, including the age of the victim, family situation, detailed time of the murder, location of the murder, and the process of the murder. Most of them are similar to what Lin Xiuran said before. Lu Siyu looked at the projection. While recording all the information in the notebook.

"...The victims were all women, with long hair, wearing silk stockings, and were killed alone at night. There were traces of the assault on the suspect’s body, but the speckles were not found in the body of the deceased. They were only found on some belongings. Considering that the murderer may have some functional impairments. No connection was found between the three victims. Our investigation results believe that this is a random crime committed against a young woman..."

When Tian Ming said this, Gu Juju interrupted his report with a ugly expression: "Team Tian, ​​this is the result of your investigation in the past few months? You don't need to repeat what everyone knows. You can read the file. You can pick the key points. Just say it."

Tian Ming was held accountable by the leader and bowed his head and said: "There are no witnesses in this case, and there is little effective information. We have always investigated as a long-term case. We have obtained the suspect’s DNA, fingerprints, footprints and other information, and we have also found it. Some suspicious suspects, but the comparison results are not consistent..."

Song Wen heard this and understood the difficulty Tian Ming encountered. Because the murderer committed the attack late at night, although he left a lot of physical evidence, but there was very little witness information, he could not narrow the scope of the suspect. There are some in Nancheng city. There are millions of men of the right age, and there are hundreds of thousands who meet the conditions. To find that person is no less than finding a needle in a haystack.

Gu Ju snorted: "What about the behavioral route? The murderer must have met the victim in some place. Have you analyzed the behavior logic inside?"

The occurrence of the case shows that the murderer must have met the victim at some point in the past, and finding the meeting point is one of the ways to start detection.

In the past, the lack of cameras and the imperfect criminal investigation techniques led to many cases becoming unsolved or unsolved for many years. But now, there are electronic eyes everywhere in the city, and DNA can be released within a few hours. result.It's a bit unreasonable that the suspect has not been found for so long, and there is even no effective clue.

Tian Ming was even more aggrieved: "After the first case, we used to spend a month looking for various cameras, but because of the remote location of the crime, only two videos showed a single victim. It is impossible to infer the meeting. Point, after the second victim appeared, we also carried out investigations, but nothing was found..."

Subsequently, Tian Ming projected and released one by one route analysis maps, and superimposed them. Three routes without intersection appeared on the map of Nancheng.

"Gu Ju, the routes of these victims are completely different. The first victim was killed when he went home, and the second victim was killed when he left home after quarreling with her boyfriend. His boyfriend had an alibi. The third They went home temporarily and were killed after getting off the night bus. Except for the first one, the remaining two were on temporary trips. They might not even go out that night. They were killed in different locations in the city. ..."

All three cases are highly random.

Gu Ju heard that the second team had worked hard but gained little, rubbed his temples, and his tone eased: "Of the three cases, there must be common points that you haven't found." When asked about this, he turned to ask Song Wen, "Where is Song Wen, you went to the scene today, did you find anything?"

"At the scene this morning, we found a piece of gauze dropped by the murderer, with some dried blood on it, in an arc shape. It seems that the murderer may have been bitten by some animal not long ago. The specific material evidence has been submitted. Material Appraisal Center.” Song Wen continued, “Others, we just intervened in this case, and we don’t know the details of the case yet... I just feel that the victim’s mask and clothes were put on again. This phenomenon is very special.”

Tian Ming and the others did not have any effective clues after investigating for several months. Song Wen and the others only contacted the case for one morning, and it was difficult to make more progress.

Gu Ju unplugged the pen cap from his hand and plugged it in. He bowed his head and said nothing. He also knew that he was a little worried. In the past few months, the second team has been working overtime and the case is deadlocked. This is something no one wants to see. Scenery, this is also the reason why he introduced Song Wen and the others.

Thinking of this, Gu Ju sighed: "I hope that no new victims will appear."

At this time, Zhuang Yi, who had been listening next to him, said: "Gu Ju, after listening to your case, I have some ideas now, but they are not perfect yet."

Gu Ju heard this, and the wrinkles on his face dispersed for a moment: "Professor Zhuang, don't let it go if you have any opinions. You are the best at psychoanalysis. Even if you are immature, you can provide them with ideas. If the uncertain direction is correct, the case can be solved as soon as possible."

Zhuang Yi stood up and said to Tian Ming: "Thank you, Captain Tian, ​​to project the first few photos of the scene."

Tian Ming hurriedly projected the photos. The three victims were lying flat on the ground. Their postures were almost the same. They all covered their faces with their clothes. The necks were marked with red strangulation marks, and their skin was pale. Crippled.

Zhuang Yi coughed lightly and began to analyze in a deep voice: "Death by suffocation is a completely different method from other deaths. It is not so bloody, but it is violent enough. Especially for male murderers, this is a kind of death. A manifestation of power."

"For a long time, this method of death has also been relied on by various murderers. There are countless similar serial cases, the most typical of which is the recently cracked Hwaseong serial murder case in Country H. There is also the famous Rainy Night Butcher. The case. But the current case is a little different from the usual similar cases in the past. I have been thinking about it. Clothes covering the face are still ordinary. What does the feature of helping the victim take care of the remains?"

Tian Ming looked up and said, "Guilty?"

In the general interpretation of criminal psychology, this type of behavior is explained in this way.Song Wen also mentioned this view before.

When Lu Siyu heard this, he stopped recording, bit the nail of his thumb, and looked at Zhuang Yi.He also wanted to hear how this person analyzed this.

Zhuang Yi nodded: "Yes, but I don't think this kind of guilt may belong to the brutal murderer. I think there are other possibilities."
