After questioning the witnesses, Song Wen and Lu Siyu went to the forensic doctor's office on the second floor of the city bureau together. Recently, the forensic doctor has also started to work overtime for this troublesome serial murder case, especially the case that happened just this morning. By afternoon, the autopsy report had come out.
Now Lin Xiuran and the other forensic doctors went to the police, and only Dragon Boat Festival stayed to watch the house.
Song Wen was also not seen, and self-sufficiently went to get the autopsy reports of the three cases and lined them up together. Then open the photos and look at them one by one. He had already seen these pictures and volumes during the morning meeting, and at this time he planned to read them carefully.
Lu Siyu also picked up the information on the first case and sat quietly watching.
I just ate at this point on the Dragon Boat Festival, and I ate a bowl of pork liver noodles next to me, making the entire forensic room smell of food. He looked at Song Wen and Lu Siyu attentively, moved a stool and sat next to him: "Song team, I have always been interested in your criminal police solving cases. Your team has always solved cases quickly and accurately, why don't you teach me..."
Song Wen didn't lift his head, and continued to organize the information in his hands, saying: "It's not that difficult, you go back and try to apply with Brother Lin to see if he will let him go."
"Hey, I'm just joking." Duanwu said, and looked carefully, making sure that Lin Xiuran did not come back suddenly, and then continued, "Song team, these victims died of suffocation. The cause of death is simple and clear. As for the corpse, Director Lin inspected it personally, Team Tian has already looked through these documents many times before, the corners are all wrinkled, and nothing new can be seen."
Song Wen flipped through the documents: "If you can't see anything, that's because he's stupid."
"No... I mean, can you solve the case after reading these again?" Dragon Boat Festival asked the question in his heart.
Song Wen finally raised his head and glanced at him, "Do you know what it means to read a book a hundred times and see for yourself? I am looking at the materials now because we have not been to the scene of the first two cases. If we have been to the scene, many scenes The information was imprinted in my mind, and now I can only rely on reading materials to make up lessons. To solve the case, these basic conditions have to be memorized.”
Having said that, Song Wen touched Lu Siyu who was beside him, his voice lowered an octave unconsciously and softened: "Look at this photo, I think the first victim and the other two Not quite the same."
Lu Siyu turned his head to look, and the Dragon Boat Festival also turned his head curiously.
It was a detailed picture of the scar on the neck of the first victim. Song Wen pointed to the scar on the victim's neck. Pale neck swollen, with a lot of red bruises, looks more serious than the second and third.
"Well, the reason is that the body of the first victim was laid for two days. When we arrived, it was swollen and rotten..."
Before the Dragon Boat Festival was finished, he was interrupted by Lu Siyu. He took the photo and looked at it carefully, then nodded to Song Wen and said, "That's right. The first case is really different."
Dragon Boat Festival suddenly felt that his face hurt from being beaten, but he opened his eyes and couldn't see anything abnormal: "This... What's the difference?"
Lu Siyu explained: "In general, the strangulation marks are deeper, wider and more uniform than the other two. Such scars may not be left by one strangulation, but by multiple strangulations. It's just that the strength is not big each time, and the corpse was swollen at that time, so it's not very obvious."
In other words, those red marks are not one or two, but multiple, connected together. The resulting scars are wider and more pronounced.
Dragon Boat Festival turned over the other two files, and as expected by Song Wen, he did not expect that these two people would find something in the previous files so quickly, and he sighed in praise: "Song team, you observe this. The power is really good…”
Song Wen didn't have time to compliment the Dragon Boat Festival, and discussed the case with Lu Siyu: "That means, the first victim is probably not killed by strangulation, and may have been strangled several times until she was unconscious, and the murderer killed her. As a toy, Le fainted and played with it for a while, and then she woke up and committed the murder again. There may be three or four such actions, relatively speaking, the second and third cases are much easier to start with."
This kind of killing method is undoubtedly long and tortured. The victim is repeatedly injured, extremely desperate, unable to break free, as if in an endless hell. It may be more painful than killing her directly.
"It's not necessarily intentional." Lu Siyu blinked, biting his nails and deduced, "perhaps, he didn't make up his mind to kill the victim at first; maybe, he was enjoying this kind of cat playing with mice. the fun of it; maybe, the first female victim reminded him of someone who inspired him to commit the crime; maybe, there are other reasons we don’t know now.”
This first case is indeed a bit special. What kind of murderous and perverted person is this murderer? Lu Siyu became more and more interested in him. He closed the file and said, "I want to go to the places where the first two crimes happened."
Song Wen and Lu Siyu asked Fu Linjiang to stay in the police station, and the two drove out of the police car. The police car drove all the way and arrived at the first place where the woman was killed, which was by the river in Lotus Hall. The surrounding greenery is very good, it is said to be a river, but it is a small ditch two meters wide.
Several months have passed now, and the traces of the river have long been wiped out by the wind, sun and rain. People pass by from time to time during the day, and it is quite fragrant.
When he arrived at the location, Song Wen took out the photos of the scene and checked it before he dared to confirm that it was here.
The two circled around, and Song Wen asked Lu Siyu, "Have you found anything?"
Lu Siyu licked his lips: "I'm thinking about a question, why is the first victim so old..." He pondered for a moment, recorded it in the notebook, and asked himself, "Maybe... it was with the murderer's subconscious. Oedipus is related."
Then Lu Siyu made a mark. The two simply simulated the scene, calculated the time and route of the crime, and then went directly to the location of the second crime. The two locations were not too close or too far apart. It took twenty minutes.
Then came the third time. Song Wen and the others believed that the third attack should have been in the small park behind the community where Zeng Minyi was located. This place happened last night. The staff just left. There were still some messy fighting marks on the ground, as well as a bloodstain or two, all of which were consistent with Zeng Minyi's testimony.
Finally, there is the fourth place, which is the place where Wang Xiaopei was murdered. They had come to this place in the morning.
Four victims, all over the place of the crime.
Song Wen's car followed the murderer around the city. By the time he was done, it was almost six o'clock in the afternoon.
The two returned to the car, and Song Wen started the driveway: "Let's go home, you didn't rest well this morning."
Lu Siyu snorted, and looked down at the map research, with a very focused expression: "The murderer should be familiar with this urban area, and often walks in these places, so the chosen location seems random, but in fact, some are just at night. In a very quiet place, he may have been lurking nearby for a while, waiting for a victim to his liking to enter his attack range."
Then Lu Siyu looked for the murderer's starting point between several points: "Assuming that the murderer started from home, then he needs to go back and forth, especially yesterday, he failed the first crime at eleven o'clock at night, and then The dog bite was bandaged and the victim appeared at another location just after 3am. I'm thinking about what means of transport the killer used to move between these locations."
Song Wen thought for a moment: "From the descriptions of the witnesses before, the murderer has calluses on his hands. He is obviously a person who does manual labor. His clothes are also very ordinary... I tend to think that he does not have a car or other means of transportation."
Lu Siyu nodded in agreement: "Tian Ming has been looking for surveillance video for a long time before, if the murderer is driving or taking a taxi, he will be found, leaving traces... So the rest, bicycles, night buses... After being bitten by a dog , according to the size of the wound, it is inferred that his injury is not minor, in this case, it will cause difficulty in his movement, and walking and cycling can basically be ruled out."
He frowned when he said this, "And his pending cooperating accomplice, the theory that Zhuang Yi said before, I always feel that some parts make sense, and I feel that there are some problems."
Song Wen continued to drive: "Follow these clues to investigate first. I think the city bureau's police force may not be enough. I will apply for it with Gu bureau and investigate the nearby area."
He thought for a moment and then said, "You need to call the monitoring of the night bus, pay attention to the nearby 24-hour clinic, the visit will take time, and there may be some results. However, on the night bus, the camera is not very clear, and there are blind spots, only Can check."
Lu Siyu drew another circle on the map. The murderer was obviously not a "wandering attacker", but a "waiting hunter". According to the "criminal circle hypothesis theory", a map was drawn, and the murderer had a high probability of living here. within the range.
The so-called crime circle is a circle formed once in a series of cases.
Within this area, there are a demolition building, several shanty towns, a bus terminal, several residential areas, several construction sites, a very large wholesale farmers market, and the only wharf in Nancheng.
The range is still too big...
Song Wen drove the car, Lu Siyu pondered the case, looked sideways out the window, and the two became quiet for a while.
As dusk is approaching outside the window, it is the peak time for get off work and meals. Adults leave work, children leave school, elderly people prepare for square dance, ordinary people enjoy the fun of life, and the whole city is in a peaceful state.
Many people don't know that there is a murderer in the city now. He ate the same food, drank the same water, and breathed the same air as they did.
He might be hiding somewhere in the city, he might be a street vendor buying fruit, he might be a construction worker carrying steel, or he might be a man sitting on the side of the road.
Three women have already died at his hands, and soon, there may be more victims...
Because of the case, the two of them were very worried and the air pressure was too low. Song Wen couldn't help but ask Lu Siyu: "So what... what to eat at night... "
"What do you want to eat?" Lu Siyu said casually: "Red braised beef? Tianma chicken soup? Panlong eggplant? Hot spring egg pork bone udon noodles?"
"It's okay." Song Wen nodded quickly, and said that his saliva was about to come down. He added: "The case has not been solved yet, don't work too hard, just do something simple. Today, Bureau Gu sent a message, In the evening, Zhu Xiao's information will come, and I have to check it." He paused and said, "Anyway, as long as it is made by you, I like to eat it."
Lu Siyu hummed: "When the case is solved..."
As soon as the two drove the police car into Lu Siyu's community, Fu Linjiang's phone number arrived, Song Wen pressed out, and Fu Linjiang's voice came out: "Song team, we have some situation here. The family of the last deceased. , Wang Xiaopei's parents, who just recognized the body in the afternoon, and then... They told reporters the news of their daughter's murder, and just now a group of media came in here to cover this case." He paused, "And, more The worst thing is that someone posted the statement that the police suspected that there were two murderers on the Internet..."
Song Wen frowned. Those are still under investigation, especially the theory that there are many murderers. Although there is now Zhou Yi's theory and a vague testimony of a witness, it still cannot be used as a basis for deciding the case. How can this matter let outsiders Does anyone know
Song Wen asked, "How did Gu Ju deal with it?"
"Seeing that things can't be sealed, he just called us for a meeting in the bureau, and Zhuang Yi was there. At the meeting, we discussed it urgently, and then Gu Bureau thought of a way. He heard that Zhuang Yi will record in the near future. A program. On the program, I want Zhuang Yi to disclose the case information and profile to the public, and publish the portrait of the perpetrator."
Song Wen immediately felt that this behavior was too risky: "This may change the case. It will also cause public panic."
Fu Linjiang said: "Yes, Professor Zhuang didn't agree at the beginning. He said that his previous analysis was only a theory, and there was no more evidence to support it. He should not disclose some remarks to the public."
Song Wen also understood this line of thinking and asked, "And then what?"
"Gu Bureau said that there is a lot of noise on the Internet now, and the media already know that, instead of letting the media scribble, it is better to take the initiative to tell them everything about it. Public criminal profile is also a common method of criminal investigation at home and abroad, and the media's disclosure will put pressure on the murderer. There are some cases in China that have done this before. For example, the murder case of a boy’s dormitory that shocked the whole country before, and the case of a college student killing his mother, were disclosed to the media early, and the public’s report also played a role in the pursuit and escape. some positive effects."
"Does Professor Zhuang agree?"
"In the end, I was persuaded by Bureau Gu." Fu Linjiang said again, "In short, it's basically settled now, and the superiors have given instructions. Bureau Gu asked me to say hello to you."
Song Wen hummed, then hung up the phone with a few polite words.
"Now that the situation has expanded, it's not an option to hide it." Lu Siyu whispered aside, the more evasive he was at this time, the more counterproductive it was, "Since you can't stop it, just let them go, and like this It is also a good thing to do, and the public can be vigilant, and it can also reduce the occurrence of murders.”
Song Wendao: "I understand that disclosing the information will be beneficial to the investigation. You can open a reporting hotline and set a bounty to see if there are more clues. But I am still afraid of irritating the murderer."
Overall, this thing has pros and cons. Just publicizing the information will increase a lot of unstable factors. It's just a gamble now.
"You don't have to worry too much." Lu Siyu said, "If the news is not made public, the murderer will not stop killing people. After it is made public, whether the murderer moves or doesn't move, he will be passive. It's just that I think... "
He stopped talking here.
"What do you think?" Song Wen heard something in his words.
"I think... It seems that it was intentional to leak the case information to the media and reveal the police investigation situation." Lu Siyu said softly, this was just his vague feeling, and there was no actual evidence, some people seemed to think Online, in the media, make the case big.
Song Wen frowned slightly. Are these deliberately manipulated by someone behind
The people's memory and energy are limited, and this case quickly overshadowed the previous Wushan Nursing Home, the Christmas car accident case.
Nothing captures the attention of the public more than a sudden appearance of a serial killer.
So behind this, is someone diverting people's attention
Is the appearance of Zhuang Yi by accident
