It's the third day that the task force has been here, Song Wenjia got up very early this morning, and the weather today is much sunnier than before, which makes people feel comfortable, Song Wenjia is worried about the work that was not done yesterday, so he walked quickly towards the police station, and he has been here for three days unconsciously, but there has not been much progress in the case, Song Wenjia thinks that these elites are really a little embarrassed.

As soon as Song Wenjia walked into the office, he saw a person, but this person Song Wenjia didn't know, this person stood in front of the blackboard full of photos of the scene, quietly looking at these photos, from the back it was a man, very strange.

Song Wenjia was startled at first, and then slowly approached, out of vigilance, her hand kept touching her gun.

"Who are you"? Song Wenjia said in a very serious voice: "Turn around."

The man was stunned when he heard the voice, turned around and said, "Who are you, you walk without a sound, you startle me."

Song Wenjia took out the matching gun, and in order to bluff, she deliberately made her voice loud and said: Who are you?

The man was a little annoyed and said, "Who do you care who I am?"

Song Wenjia said loudly: No matter who you are, now raise your hands above your head.

The man slowly raised his hands above his head, and looked at Song Wenjia with unscrupulous eyes, and Song Wenjia's eyes when he looked at him instantly had a feeling of being seen through, which made her very uncomfortable.

"The way you hold a gun, I have several ways to snatch your gun."

Song Wenjia was a little annoyed and angry: ...... you

Before the words were finished, the man interrupted: This kind of 9mm caliber pistol, although the recoil is not large, but it is not something that you can hold with one hand as a girl, not to mention that you are just a forensic doctor, you should not have fired a gun.

Song Wenjia was stunned for a moment, looked at the person in front of him who didn't know and said: How do you know that I am a forensic doctor?

"You smell of formalin".

Song Wenjia said again: Then how do you know that I don't know how to use a gun?

"That's because ......"

Before the man finished speaking, he stepped forward and grabbed Song Wenjia's hand, and easily snatched the gun down with a lift up.

Song Wenjia looked stunned and a little overwhelmed.

"Remember to turn on the safety next time you point a gun at someone."

"Put the gun down and raise your hand," Lin Yunfei shouted as he burst in.

Li Yong also came in at this time: put down the gun and his own people.

Lin Yunfei said reluctantly: The team leader ...... this person just now

Li Yong waved his hand and said: They are all their own people

"Old Gu, you're finally here, great, let me introduce you to you, this is my old friend named Gu Yue, the one I mentioned before." Li Yong said: With him to help us, this case will be solved soon.

Li Yong pointed to Lin Yunfei and Song Wenjia to introduce Gu Yue.

Gu Yue smiled and said: I'm sorry just now, it's nice to meet you.

Li Yong: Now that you've arrived, let's help solve the case as soon as possible.

Gu Yue looked at a few people and said: No, aren't these elites you are looking for, why haven't you solved the case for a few days.

Li Yong said with a smile: The elite is the elite but they don't have much experience, and this case is really tricky.

Gu Yue said: How bad is it?

Li Yong said: It can't be worse.

Li Yong wanted to lead Gu Yue to understand the detailed process of the case, but he didn't expect the second body to appear.

This is the third day that the murder happened again, followed by the report of the missing person, the missing person is Tang Zhuzhu, female, 29 years old.

The place where the body was dumped was still by the lake, the task force and the local police immediately rushed to the scene, the scene was already full of onlookers, the family of the deceased held the body and wept bitterly, a woman screamed and wailed, no one was allowed to touch the body, the police had no choice but to separate it first, and the police confirmed that the deceased was the missing Tang Zhuzhu.

Director Xu realized the seriousness of the matter again, and this time it was likely to be a serial BT killer.

Tang Zhuzhu's mother passed out crying and crying, and the police took a lot of effort to cordon off the scene and investigate the scene for photo collection. This case is a little different from the first one, the first case the female corpse was naked, and in this case the female corpse was wearing clothes, and this case was also a throat cut, sexual

, cut the flesh and stick the scales.

After studying the case file, Gu Yue let out a sigh of relief and said: Let me ask a question, what is the murderer's motive for killing?

Gu Yue continued: In the first case, the female corpse was naked and the clothes were gone, and in the second case, the clothes of the female corpse were still there, and the clothes of the deceased were missing, and there were two possibilities: one was thrown by the murderer, and the other was collected by the murderer, I think the latter is more biased, because if he was thrown by the murderer, then he could have thrown it away together when he threw the corpse, but he didn't.

Lin Yunfei questioned that it was possible that he had thrown the deceased's clothes somewhere else, buried them, or burned them.

Gu Yue said: He hasn't buried the body yet, so why bother to hide the clothes of the deceased?

Gu Yue saw that everyone did not question it anymore and continued: If the clothes of the deceased were collected, then why didn't the second corpse collect the clothes, was it only interested in the bride's clothes? The killer we are dealing with is likely to be picking the victim at random.

Song Wenjia saw that Gu Yue finished speaking and continued, in the comparison between the first female corpse and the second female corpse, some differences were found, first of all, the difference in knife marks, and secondly, the time of cutting the skin was different, the first female corpse was cut long after death, and the second female corpse was cut at the first time. Moreover, the scales on the abdomen of the female corpse Tang Zhuzhu have traces of being rubbed off, which is likely caused by the murderer carrying the deceased when he threw the body.

Song Zetao said: Is it possible that the murderer didn't want to do this at first, but then suddenly thought of it and got out of control.

Li Yong said: You said this to remind me of a thing, the corpse abandoned by the murderer died three days ago, so where were the two corpses in these three days?

Everyone was taken aback by Li Yong's words, the perverted murderer may be a necrophile.

Gu Yue said: My psychological profile has written a rough model, the murderer is in the prime of life between 35-40, has mental problems, is unmarried, and has a very poor living situation.

Lin Yunfei said: This is just your conjecture.

Gu Yue said: To be precise, this is called psychological profiling, and for a long time in the United States, there has been a behavioral analysis department about psychological profiling, although many people think that this is a pseudoscience, but its solving rate is beyond doubt, and this is calculated step by step, not random conjecture.

Serial killing, that's a terrible word.

In the United States, a pair of brothers immediately killed and extracted bone marrow, and used their limbs to feed pigs, which are omnivores, killing 89 people and leaving 89 pairs of shoes.

According to Gu Yue's profile, the police cooperated with the Beihu Village Committee and the surrounding village committees to investigate, and finally found a person who matched him, this person's name is Fang Dawei, 41 years old and no daughter-in-law, and everyone in the village calls him Fang Fool, which is why he can't find his daughter-in-law.

The task force immediately went to Fang Fool's residence, only those who had been to the countryside knew what the wall of earth looked like, when the task force and everyone stood in front of this crumbling earthen house, Fang Fool staggered over and looked at everyone.

The village secretary shouted loudly: Fool, what have you done, this gang has come to arrest you.

Fang Fool said: Arrest me, arrest me and beat me?

The village secretary seemed to be a little happy and said: You can't be arrested if you kill someone.

Fang Fool said: This is not nonsense.

The task force watched as Fang Fool opened the door, but there was no lock on the door, it was tied with a wire.

So far, there are still some rural households whose doors are tied with wire.

The task force followed Fang Fool into his small courtyard, the courtyard was full of weeds and dilapidated, the task force conducted a series of inquiries, Gu Yue walked around the room during the question, the room was not ordinarily small, and it was divided into two with a piece of cloth with a rope in the middle, the inside was a sleeping place, and the outside was a place to eat, and the arrival of several people in the task force made the room extremely crowded.

Li Yong said: Where were you on October 28th?

Fang Fool said: I don't know how many numbers there are today.

The task force asked a few more questions one after another, and found that this Fang fool did have some problems in terms of spirit, not like he was pretending, just when the task force was about to leave, Gu Yue found a basin under the bed in the other half of the room, there were two fish in the basin, there were no fish scales on the fish, and it was a carp. The task force took Fang Fool back to the police station for interrogation According to Fang Fool's answer, the two fish were scraped and ready to be eaten, and Director Xu asked him where he got the money to buy fish, and he replied that he caught it in the lake, and the police could only keep it for a while and take DNA.

Director Xu was a little embarrassed and said: DNA identification will take three days at the earliest.

Li Yong said: We can't wait that long, the two murders, not to mention how the media reported them, and the families of the deceased have no way to comfort them.

A policeman said: Otherwise, we will go to his house and search him, find evidence, and then arrest him.

Gu Yue said: What if you can't find it?

The policeman stopped talking.

Everyone was silent for a while, Gu Yue also stayed aside and didn't speak, he looked at the photos of the scene carefully, the more he looked at it, the tighter his brows became, and he muttered to himself while watching. Li Xuemeng, what connects you to Tang Zhuzhu? Li Xuemeng's clothes are gone, Tang Zhuzhu's is still there, and the knife cuts on the necks of the two deceased do not belong to the same knife, is it just the murderer who changed the knife?

Isn't there really anything strange about the first deceased being cut long after his death, and the second being cut in the first place?

Where is the murder scene?

What exactly is the murderer trying to do?

Gu Yue's mind was like a movie, passing all the pictures in front of him one by one, Gu Yue remembered what his master said, there is no absolutely perfect crime.

There are many cases that have been solved with just a few subtle clues.

A woman was stabbed to death in Lunan District, Tangshan City, and the police cracked the case based on a white plastic bag 20 meters from the scene.

Gu Yue wrote all the relationships and all the possibilities with a pen in front of the blackboard plastered with photos of the scene, and for nearly an hour, Gu Yue stopped and turned around and picked up the cup of boiled water on the table that had been cooled and drank it all and said: I have a bold idea.

Li Yong hurriedly said: What do you see?

Gu Yue glanced around at everyone and said: There is also a murderer.
