Criminal Investigation Files

At ten o'clock in the morning, Song Wen brought Lu Siyu and Fu Linjiang to the conference room of the Nancheng Bureau. Tian Ming and Zhang Ziqi from 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.

To Song Wen's surprise today, there was a freshman sitting beside Gu Ju.He turned his head to look at Tian Ming with some doubts. Tian Ming obviously didn't know him either. He waved his right index finger at him, and then spread his hands to show that he knew nothing.

The man looked about 35 or [-] years old. He wore glasses and had curly hair. He looked refined. Seeing that this man looked familiar, Song Wen couldn't help but take a few more glances.

Seeing that everyone was looking at the man, Gu Ju introduced with a light cough: "Because this case is special, I invited Mr. Zhuang Yizhuang, a professor of criminal psychology who was recently recording a program here, to help us analyze the case together, let's see Could you have some more clues?"

The man named Zhuang Yi was modest: "I'm just an ordinary researcher, and I'm here to discuss and study with you."

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

Over the years, Zhuang Yi has also appeared on many legal programs, and is a frequent visitor to several variety shows.Song Wen has also watched some of those programs, and this teacher Zhuang would throw out amazing opinions every time, and the words were not surprising. Those analyzes sounded appalling at first, but when you think about it carefully, they make sense.His eloquence is good, he has an obvious personal style, and he has many fans on the Internet.

However, Zhuang Yi's style has aroused opposition from some old scholars. Those old experts think that Zhuang Yi's psychological foundation is not solid. applied to actual cases.

Some people even pointed out that Zhuang Yi's academic qualifications were fake, and the analysis was based on the script of the TV station. , copied from the paper.

But they scolded, Zhuang Yi was still very popular. This time he came to Nancheng to participate in the new popular science program on the rule of law opened by Nancheng TV Tower.Just in time for a serial murder case to occur here, Bureau Gu was at a loss what to do, so he invited this expert to see if he could help the case.

At the beginning of the meeting, Lin Xiuran and Xu Yao presented various evidences and autopsy results of the third victim at the scene. It was exactly the same as the previous two cases. The victim was 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. At present, the identity of the suspect has not been confirmed."

Compared with the existing database, there is no result, which means that the suspect has no criminal record and his fingerprints have not been entered into the system.

Theoretically, anyone who has a criminal record should be able to find information in the database, but our country is vast and sparsely populated, with a complex structure and high turnover of personnel, so the accuracy of this database can only be used as a reference .

"I think the murderer in this case has a certain tendency to violence and may be a habitual offender. Although we didn't find it in the database, you should not take it lightly. Some civil lawsuits and referees who have not been sentenced should also be investigated. Take a moment." Gu Ju turned his head and asked, "Tian Ming, your team has been pursuing this case for several months, let me introduce the situation of these three cases."

Tian Ming nodded, and gestured to Zhang Ziqi, the deputy team member of his team. Zhang Ziqi then projected the pictures and information of several victims on the projector.

For a while, the scene of several victims being killed appeared on the projector one by one. They were all female corpses one by one. The scene was not bloody enough, but it was scary enough to make people shocked.

"The first victim, Li Ling, was 38 years old... The second victim, Zhang Yajie, was 27 years old... The third victim was killed this morning and his identity has just been confirmed. 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 murder time, murder location, murder process, most of the situation is similar to what Lin Xiuran said before, Lu Siyu looked at the projection, Write down all the information in a notebook.

"...The victims were all female, with long hair, wearing stockings, and were killed when they were alone at night. There were traces of assault on the suspect's body, but the sperm spot was not found in the body of the deceased, but was only found on some belongings. Considering that the murderer may have some functional impairments. No connection was found between the three victims, and our findings suggest that this is a random crime targeting young women..."

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

Tian Ming was held accountable by the leader, bowed his head and said: "There are no witnesses in this case, and there is very little effective information. We have been investigating it as a long-term case. At present, we have obtained the suspect's DNA, fingerprints, footprints and other information. We have also found Some suspicious suspects, but none of the comparison results match..."

Hearing this, Song Wen understood the difficulty Tian Ming encountered. Since the murderer committed the crime in the middle of the night, although he left a lot of physical evidence, there was very little witnessing information, so he could not narrow down the range of suspects. There are millions of men of the right age, and there are 10,000+ who meet the requirements. Finding that man among them is no less than finding a needle in a haystack.

Gu Ju snorted: "What about the line of action? The murderer must have met the victim somewhere. Have you analyzed the logic of the action?"

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 starting methods for detection.

In the past, cameras were missing and various criminal investigation techniques were not perfect, which led to many cases becoming unsolved or unsolved for many years, but now, electronic eyes are everywhere in the city, and DNA can be revealed in a few hours. result.It's a bit unreasonable that the suspect has not been found for so long, and there are not even effective leads.

Tian Ming was even more aggrieved: "After the first case happened, we spent a month looking for various cameras, but because the location of the crime was remote, there were only two videos showing a single victim. It was impossible to deduce that the meeting At this point, after the second victim appeared, we also conducted an investigation, but found nothing..."

Then Tian Ming projected and released route analysis maps one by one, and superimposed them, and three routes with no 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 out and returned home. The second victim was killed when he left home after a quarrel with his boyfriend. His boyfriend had an alibi. The third victim I went home temporarily and was killed after getting off the night shift bus. Except for the first of these three victims, the remaining two were on temporary trips, and they might not even go out that night. They were killed in different places in the city ..."

These three cases all have strong randomness.

Gu Ju heard that the second team worked hard but gained little, rubbed his temples, and softened his tone: "In the three cases, there must be something in common that you haven't found yet." At this point, he turned to Song 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. There were some dried blood stains on it in a circular arc shape. It seemed that the murderer might have been bitten by some animal not long ago. The specific physical evidence has been submitted to the The Center for Biological Sciences." Song Wen continued, "Others, we just got involved in this case, and we don't know the details of the case yet... I just think that the victim's face was covered with clothes and makeup, and this phenomenon is very special."

Tian Ming and the others searched for several months but found no effective clues. Song Wen and the others only got in touch with the case for one morning, so it is difficult to make more progress.

Gu Ju pulled out the cap of the pen in his hand and put it back on again. He bowed his head for a while, knowing that he was a little anxious. In the past few months, the second team has been working overtime. The stalemate in the case is something that no one wants to see. This is 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 by the side, said: "Gu Ju, after hearing about your case, I have some ideas now, but they are not perfect yet."

After Gu Ju heard this, the wrinkles on his face loosened a bit: "Professor Zhuang, if you have any opinions, don't make a fool of yourself. You are best at those psychological analysis. Even if you are immature, you can still provide them with ideas, say If the uncertain direction is correct, the case can be solved as soon as possible.”

Only then did Zhuang Yi stand up and said to Tian Ming, "Captain Tian, ​​please project the first few photos of the scene again."

Tian Ming hurriedly projected those photos. The three murdered women were lying flat on the ground. Their postures were almost the same. Their faces were all covered by clothes. There were red marks of strangulation on their necks. Their skin was pale and somewhat creepy.

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

"For a long time, this way of death has also been favored by various murderers. There are countless similar serial cases, the most typical of which is the Hwaseong serial murder case that was just cracked in country H. There is also the famous rainy night butcher before. However, the current case is somewhat different from the conventional similar cases in the past, and I have been thinking about it. It is still common to cover the face with clothes, and what does the feature of helping the victim take care of the remains explain.”

Tian Ming raised his head and said, "Guilty?"

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

Hearing this, Lu Siyu stopped recording, bit his thumbnail, 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 is necessarily owned by the brutal murderer. I think there are other possibilities."
