On the way back to the police station, Daji had a guess that she would go headlong into the autopsy room when she returned. In fact, in the police station of a prefecture-level city like Mozhou, there is no special DNA testing equipment, but I don't know what method Daji used, and soon, she came to a conclusion that the two mutilated kidneys were all female deceased.

This was both expected and unexpected, and I felt bloody and disgusting when I thought of those two kidneys, especially since they were crawling with white maggots.

I didn't think about it anymore, but what made me amazing was that he actually ate people, and he ate half of those kidneys.

This was not until the next day, after other colleagues from the police station also went to work, I asked Xiao Liu about the situation. Xiao Liu is the technical police officer who is responsible for tracking down Caicai's mail this time.

He replied that the conch butcher sent emails with his mobile phone, and the IP of the mobile phone was determined by the base station near the mobile phone, and the Internet IP was different each time. In addition, that guy is very cunning, and after he finishes on the Internet, he turns off his phone. In other words, there is no progress on his side at the moment. I gave him a few more words of encouragement.

Xiao Liu was not discouraged, he also had a trick, telling me that he would go to the hostess, to install a monitoring software in the other party's computer, as long as the conch butcher sent an email to the hostess, the software would automatically remind and track the other party's IP address, if we were lucky, maybe we could catch the conch butcher in time!

I think of a sentence, knowledge changes fate, Xiao Liu's move is really likely to make a contribution.

And an hour after Xiao Liu and I ended talking, something happened that I didn't expect, Caicai called.

She went straight to me. I guess Xiao Liu gave her my phone.

I thought there was another case, who knew that Nana was okay at all, she just wanted to talk to me, and finally clicked again, hoping that I could save her contact information, so that if there was any news about the conch butcher, she could find me as soon as possible.

I casually agreed, but also told her that I was not on duty 24 hours a day, and when I was in danger, calling 110 was the most effective.

Daji didn't know where she knew the news, so she took the time to find me and said coldly, "The dishes from the radio station I saw yesterday are very beautiful." ”

I didn't think about it that much, and replied along the way, "That's a must, the person is a TV host, a long water spirit!" ”

As a result, she was pinched by Daji, and she was so angry that she wanted to run to Tie Jun to suggest, which means that the conch butcher may go to the TV station to be unfavorable to Caicai, and let me be Caicai's 24-hour personal bodyguard.

No matter how stupid I am, I understand that Daji is jealous, so I laughed and interrupted to get this over.

I also took the opportunity to go to Tie Jun's office, wanting to talk to him about the TV station. But I wasn't sure if he was there, so I tried knocking on the door. Tiejun shouted, "Come in!" ”

When I pushed open the door and walked in, Tie Jun was reading the file there, and he probably smoked a lot of cigarettes, and the room was full of smoke.

I looked at the faces of all brothers, and suggested, "Brother Tie! You smoke less. ”

Tie Jun pressed the cigarette in his hand into the ashtray and sighed.

I opened the window for him, let the smoke in the house run out, and then told him about going to the TV station, and after listening to it, Tie Jun didn't say anything for a long time.

In fact, he already knew, but when I said this, it reminded him of such a messy problem.

After about four or five minutes, Tie Jun suddenly asked me, "Circle! Have you ever heard of a word called 'criminal mind mutation?' ’”

I recited two sentences silently, and my heart said what does this mean? Although I studied criminal psychology when I was in the police academy, I didn't understand this kind of advanced technical word at that time, and even if I heard it, I forgot it.

Tie Jun went on to explain, "The term criminal psychology mutation was first proposed by the French police, and later the term was deepened and elaborated by professors of criminal psychology in the United States. To put it simply, the psychology of a criminal will change constantly with the increase in the number of crimes. ”

Tie Jun lit another cigarette. I motioned for him to continue, and Tie Jun said with a smoke ring, "When the criminal is committing a crime, because he has not been caught by the police, his criminal psychology will change dramatically, and this change may also stimulate his emotions, making him contempt or contempt for the police, because he does not take the police seriously, so he will be even more crazy to commit crimes!" ”

I kind of understood, and then said, "In other words, quantitative changes will change qualitatively!" It's like a thief who starts out as a petty thief, and because he hasn't been caught, over time, he's likely to become a thief or a robber! ”

Tie Jun nodded, "That's what it means!" ”

My heart tightened, and my heart said to take the case of the conch butcher as a look, the murderer may have committed the crime randomly at the beginning, but because he has not been caught, I have a kind of conceit in my heart, thinking that we police are a group of fools, and our ability to handle cases is nothing more than that! So, he began to provoke and declare war on our police, and the letter he sent to the TV station illustrates the situation.

I suddenly had a headache, and I didn't want to persuade Tie Jun to smoke less or anything, so I took out a cigarette from my pocket and lit it.

Tie Jun has a bad guess, saying that the murder has stimulated the murderous nature in the conch killer's body, and he is likely to be no longer satisfied with simple killing, and the target of the murder is likely to be transferred! As a result, many of the clues we have previously grasped may be invalid.

I couldn't help but think of the note again, with two patterns on it. The Conch Butcher said that there is a hint of the next murder?

I didn't have the heart to say anything to Tie Jun, and it didn't take long to leave his office.

I want to try to find something through the pattern. But by noon, not only did I make no progress, but I also went to a small restaurant near the police station to eat a pound and a half of dumplings......

I also called Daji and asked her if she had eaten. I'm afraid that this little girl will be too energetic to solve the case and neglect to eat.

Daji didn't answer my call, so I simply packed one and sent it to the forensic clinic.

At this time, there was only a small forensic assistant in Mozhou in the outpatient clinic, and his eyes lit up when he looked at the dumplings.

I told him that it was for Daji, but the moment I turned to go out, I heard the little assistant's stomach growling.

I had a bad premonition, but I also secretly sighed and said forget it.

I didn't go back to the police station in the afternoon, not because I was lazy, but because I felt that my body was very dirty.

I drove straight home, took off my clothes, and went straight to the bathroom.

Originally, I thought that I would sleep comfortably after taking a shower, but after being drenched in a hot bath, I was refreshed. It's all my own home, and I don't shy away from it, so I went naked to the refrigerator and got a bottle of canned beer and sat on the sofa to drink it.

As I drank, I took out a piece of paper from under the coffee table and wrote it down. I wrote down all the characteristics of the murderer on paper, but after reading it for a long time, I still didn't have a clue.

I'm even a little strange, why would a smart murderer like him go out and find a job at will? It's not scientific!

I took a pen and drew the two patterns on the waste paper, the conch and the "cricket", but I drew it more ugly, and finally I drew the conch as a snail, and the cricket was directly drawn by me as a fluttering moth. It's completely more distracting. I stared at the two pictures for a long time and didn't have a clue.

In the end, I didn't think about it, closed my eyes and fell asleep on the couch.

At night, when I was asleep, someone knocked on my door. I woke up and inked for a moment before I leaned over to open the door.

I didn't expect it to be Daji, Big Mouth and Bai Laoxi.

The big mouth is still eating steamed buns. He didn't shy away from it, and when he saw me, he said with a spittle star, circle, why did you open the door?

The spittle was sprayed right in my face. I suddenly felt a chill, and my heart said to his grandmother, will Lao Tzu's bath be washed in vain?

I lifted my hand, touched the spittle, and told them to come and sit in the room.

Daji was very concerned about me and asked me why I didn't go to work in the afternoon. I replied simply.

I also asked them, "Is there anything about the case that came to me?" ”

Daji didn't rush to answer, but looked at Uncle Evil. I suddenly reacted that it was Bai Laoxie who took the initiative to come.

At this time, Bai Laoxie found out that the two paintings I had drawn. He changed his sad face, looked very happy, and took the painting and said yes again and again.

I felt a sense of shame, and my heart said what was good? It's all clearly out of shape.

Bai Laoxie was also in a hurry to say something serious, and after admiring the painting, Daji first talked about some of her discoveries in the afternoon. She did find the murderer's DNA from the female deceased's fingernails, and she also compared it with all the data in Mozhou and Hei Province, and there was no data match!

I understand what Daji means by this, the current DNA data comparison can only be compared with the database, and the DNA in the database is some criminals with criminal records. Due to the large number of people in the Black Province, it is impossible for everyone's DNA to be in the database, so although there is a clue to the murderer's DNA, it is likely that it is useless.

I sighed in my heart, and my heart said that another clue was broken.

Without waiting for others to say anything, Bai Laoxie pointed to the painting and interjected and asked, "Small circle, come on, tell me what you found about these two patterns?" ”

I can't help but answer, so I simply contacted the criminal psychological mutation that Tie Jun said before, and played it temporarily.

I said, "Needless to say, this conch pattern is the special symbol of the conch butcher, and he uses this pattern to prove that the letter was written by him." As for this insect, I just looked at it carefully for a long time, isn't this insect a bit like ...... Moth. ”

I didn't dare to say crickets, and Bai Laoxie didn't refute me, so I continued, "In these cases, the murderer was very cruel to the female victims, and the moth has a saying among the people that the moth has become a chrysalis and a butterfly. I wonder if the killer's next target will be to target women in the beauty industry? For example, if you are a woman in a beauty salon or a medical plastic surgery facility, I suggest that you should focus on these places and catch any suspicious clues. ”

After I finished speaking, I actually didn't have confidence in myself, but I didn't expect the evil uncle to giggle and praise and say, small circle, amazing!

I was stunned, and my heart said that it couldn't be that I was confused, right? Then I'm too genius.

And I was actually "narcissistic" too early, Bai Laoxie stiffened his face violently, and took out a rubber band from his pocket, aimed at me and threw it.

He also muttered, "You kid is messing around, you can get this!" ”
