"How is Deng Ruoyi's side?" Shen Zezhi asked.

Qi Kai said: "I went to see the scene of the crime and found no valuable clues. This Deng Ruoyi is an ordinary college student, her social interaction is not very extensive, and her interpersonal relationships are also very average. One noteworthy point is that her roommate said that she seemed to have a new boyfriend before she died, whom she met online. They said that Deng Ruoyi had been chatting with him online, but Deng Ruoyi said that his boyfriend was chatting online, and this seemed to be a student in a college town. But the specifics are not clear. ”

Zhao Jiyong said: "So this mysterious boyfriend is very suspicious? ”

Shen Zezhi asked, "What about her computer?" College students should have computers. ”

Qi Kai said: "Her computer was sent for repair a month before she died, and he didn't know the mysterious boyfriend at that time. So she has been using her mobile phone to contact him all this time. I went to the communications unit to call up her call logs, and there was no strange number. ”

Ji Ziyue: "Such a coincidence? Don't they have to call? Don't couples nowadays have to keep their phones on the phone or something? ”

"Don't forget that there are QQ, WeChat and Momo now. There are a lot of chat software, and you can also voice. Qi Kai said.

Kiko looked at him strangely.

Qi Kai asked, "What's wrong?" ”

"Do you have all these apps on your phone? That's how you connect with your girlfriend as well? Noriko asked.

Qi Kai said: "No, I only have QQ and WeChat on my phone, and I don't download Momo." Besides, I don't have a girlfriend yet. But I think you should use these apps then, you haven't had a girlfriend...... Mr. Ji. ”

Everyone couldn't help laughing, and Ji Ziyue's face turned red. For the fact that he hasn't been in love for 25 years, he has been laughed at many times.

"Ahem, get down to business." Shen Zezhi said: "Judging from the method of killing, the second deceased cannot be judged to have been committed by the same murderer. After all, his methods of killing people are all too common. ”

Qi Kai said: "But her hand also has the totem that was branded at night." ”

Zhao Jiyong said: "The murderer is telling the police that Deng Ruoyi's death was committed by him." ”

Ji Ziyue asked: "Is it possible to imitate the crime and imitate the previous murderer to divert the attention of the police?" ”

Shen Zezhi shook his head: "Impossible, Deng Ruoyi is the second person to be killed, and the previous case has not been made public, not to mention that if another murderer imitates the crime, at least the means of committing the crime should be the same as the previous one." It should be the same murderer. From a psychological point of view, the murderer should be a mature man who desperately wants to be noticed and recognized. The purpose of the killing was just to attract our attention and show off his methods and wisdom to the police. But he'll soon be content to just show off to some people, and I think he'll continue to commit crimes. ”

Zhao Jiyong said: "I guessed that he should be a man with a strong body of 170 to 180. Now, based on the clues available, it can be inferred that the murderer is not in very good health. First of all, he will not be very strong, because traces of ether were found on the bodies of the four deceased, which shows that the murderer will not be very strong. ”

Ji Ziyue said: "Judging from the method of his crime, he should have a higher education and know a lot about the use of some medicines." Moreover, he had been trained in medicine before, otherwise the body of the first deceased would not have been dissected so neatly. ”

Qi Kai said: "The murderer should not be engaged in a job that requires frequent contact with other people, he should live in a relatively closed place." He will not work in manual labor. ”

Shen Zezhi summed up and wrote: "So the murderer we are looking for should be a person about 30 years old, male, thin, highly educated, engaged in medical-related work or engaged in related work." He now works in a relatively closed environment, and there is a high possibility that he will live alone. ”

Zhao Jiyong said: "But such a person is very difficult to find. Now we have to determine how he is looking for the target, randomly, or for some particular reason. ”

Qi Kai said: "The identities of the four deceased, family relationships, and social connections are not connected at all, will it be random." Indiscriminate killing? ”

Shen Zezi said in a deep voice: "I think it's unlikely that it's random, there must be something related to the four deceased." What about Deng Ruoyi's mobile phone? ”

Qi Kai said: "It's already been sent to Guan Xin." ”

Ji Zikai used the computer in their temporary office to contact Guan Xin, and Shen Zezhi asked, "Have you found the place where the four deceased are related?" ”

Guan Xin shook her head, and she said: "I'm afraid I have to tell you a bad news, I found a similar case in Zhongzhou City." ”

"What?"

Everyone's brows furrowed.

Guan Xin fed back the information. In a homicide case in Zhongzhou City on May 6, there were two deceased, a man and a woman, and they were in a relationship. The male deceased, Zhu Feng, was 25 years old, an ordinary clerk of a bank. The female deceased, Liu Yanyan, was 21 years old and a junior at school. The bodies of the two were found in a hotel, and both died of intracranial hemorrhage after being hit on the head with a blunt object. A woman has had sex before she dies, and the semen in her body belongs to the male deceased. The strange thing is that the female died wearing clothes, but the male deceased was completely clothed. There is a totem of imprint on the inside of the wrist of the deceased's left hand.

Noriko thought for a while and said, "Stripping a man's corpse naked alone is actually a bit insulting. Zhao Jiyong said: "I originally thought that this case was only in Jinjing City, but now I found that there was a similar case in Zhongzhou City." This makes it more difficult for us to determine the extent of the murderer. ”

Shen Zezhi said: "But we are more sure that the murderer did not commit the crime randomly, and there will definitely be some connection between these deceased." It's just that we haven't found out yet. Mr. Zhao will go to Zhongzhou City tomorrow to determine whether it is a series of cases. ”

Zhao Jiyong: "Okay." ”

Shen Zezhi looked at his watch and said, "It's not early, let's get off work today." Yunqing is still undergoing an autopsy, and it is estimated that it will have to be overnight today, so let's wait for the results tomorrow morning. ”

The Tianjin Municipal Public Security Bureau has arranged a hotel for them, just one street away from the Public Security Bureau. They lived in a standard room, two people in one room, Shen Zezi and Ji Ziyue lived together.

In the evening, Shen Zezhi came out of the shower and found that Ji Ziyue was watching something on the Internet, so he asked, "What are you watching?" ”

Noriko Yue said: "I looked up the top ten perverted killers in the world, and I think the murderer in this case is likely to imitate them and continue to kill." ”

Shen Zezhi nodded, and he said: "We still don't know what his motive for killing is, and it's difficult to determine the direction of our investigation if we don't know it." ”

Ji Ziyue said: "I also think it's very strange, this person can't be a crazy person with careful thinking, his killing methods are extremely brutal without the slightest mercy." I always felt that he should have a lot of anger in his heart, and he was venting. But what is the purpose of imitating these perverted murderers? ”

Shen Zezhi sat down beside him and said, "This is indeed very strange, what does he want to express?" ”

As soon as everyone arrived at the office the next day, they saw Sang Yunqing, who was already there in advance. Sang Yunqing, who has always been a cold beauty, also has two heavy dark circles under her eyes today.

"Sister Yunqing, it's hard work." Noriko smiled and put the breakfast she had brought her in front of her.

Sang Yunqing picked up breakfast and ate a few bites, and after staying up all night and dissecting the corpse all night, he didn't have much appetite, so he put it down after eating two bites.

Shen Zezhi asked, "Did you find anything?" ”

Sang Yunqing said: "I have dissected four corpses, and according to the wounds of the deceased, it was found that although the murderer's method of killing was very cruel, he was very steady, and there were no extra wounds on the deceased's body. When the murderer killed Qin Qiaomei, he was very skilled in dissection, I think he probably studied medicine, and he should still be a major in surgery, and he is a professional in technique. ”

Sang Yunqing's discovery proved everyone's previous speculation that the murderer had been involved in medicine.

"As for the ether used by the murderer, I don't have any clues. However, the heparin detected in the blood of the third female deceased was a breakthrough. This drug is dangerous to use, so this drug will be very strict in clinical use in hospitals. Sang Yun Qingdao.

Shen Zezhi nodded after hearing this, and arranged: "Qi Kai will go and check the line of heparin."

and see if there is any catch. Mr. Zhao has already left for Zhongzhou City, and I hope he can bring us some good news. ”

At this time, there was a knock on the door of the office, and it was a clerk from the bureau.

"Team Leader Shen, Qin Qiaomei's son is outside."

Shen Zezhi nodded: "Got it, thank you." ”

Shen Zezhi stood up and said, "I'll go talk to him." ”

Qin Qiaomei's son is 25 years old and works in other places. The police contacted Qin Qiaomei after his accident, and now he lives in Qin Qiaomei's supermarket and waits for the results.

Shen Zezi saw Qin Qiaomei's son outside the reception room, and he glanced at the information in his hand. This young man's name is Qin Fei, his father divorced Qin Qiaomei when he was one year old, and then left Tianjin, and he has not been in touch for more than 20 years. Qin Fei's mother's surname, it can be seen that Qin Qiaomei's relationship with her ex-husband is really bad to a certain extent.

Qin Fei works as an editor on a similar website, with a monthly salary of about five or six thousand yuan. Not much in his city. He has a stable girlfriend, Qin Qiaomei bought him a house at the beginning of this year, and the two plan to get married at the end of the year.

Judging from the information, this is an ordinary single-parent family, and it should not cause such a murderous disaster.

Shen Zezhi pushed open the door: "Hello." ”

Qin Fei raised his head to reveal a haggard face, he couldn't find the original Qin Fei after being tortured by his mother's tragic death.

"My mother's killer has been found?" Qin Fei asked in a low tone.

Shen Zezhi put the folder on the table and sat down: "Unfortunately, not yet." ”
