From the early morning of the 13th to the discovery of four serial cases and the discovery of gaps in the criminal investigation direction on the evening of the 18th, it took six days. Overall, it was quite fast.

During the video call on the night of the 18th, Ying Mingyu did not discuss the murderer's inference with Fang Jinshi in detail, but asked them to come back quickly so that they could work together.

"We will go back to Meishi City tomorrow and bring back the corresponding evidence." Fang Jinshi and the others were in a hurry to go to Jinyang City and did not have time to bring these things. Moreover, it is not appropriate to take them to another business trip place, which may cause unnecessary

trouble.

"Thanks for your hard work."

Counting it all at this moment, Fang Jinshi and the others have been on a business trip for a whole week, and it will be the same for him tomorrow. He hasn't visited Qianqian for a week.

After hanging up, they discussed it internally, and the trace examination and forensics were not involved.

"It seems that there is a high probability that this murderer/snatched the manuscript of Chen Tongtong's novel. Maybe she was a very good writer and the murderer wanted to keep it for himself." Luo Yin felt that this was most likely the case.

"Although this possibility cannot be ruled out, the murderer did not clear the records on the other deceased's computers, nor did he take away Liu Sisi's tablet. Isn't he afraid that we will find out that he published someone else's novel?"

For the idea mentioned by Ding Yuan, they have used technology to check the entire network. If the person who plagiarized is found, it is very likely to follow the clues and catch the murderer.

"Perhaps he does not have such good anti-reconnaissance capabilities, or he will make modifications before publishing. After all, online search is not that advanced. As long as it is not plagiarism from the original text, it may not be found at all." Bao Zhan actively participated.

Ying Mingyu still lacked this kind of computer knowledge and did not interrupt.

"According to my psychological description, the murderer is not a person who plagiarizes other people's works. He has a deep literary literacy and can chat with the deceased on novel creation." Chen Chen tried to turn the tide. He did not think the murderer was

Killing people to steal other people's works.

"Perhaps it was a writer with hidden medical problems who found these dead people through communication and writing, but after meeting him, it was to vent his illicit desires." Liu Minmin did not insist on going against Chen Chen, her intuition told her

Her guess was similar to Chen Chen's, but she didn't want to agree with his statement.

"Master, what do you think?"

Seeing that Ying Mingyu didn't speak for a while, Liu Minmin pulled him.

"The cause of the murder should still be physical and psychological problems. We have only found the link between the murderer and the deceased. Next, we still need to start with the murder weapon, make a clear profile of the suspect, and narrow down the screening scope."

It seemed that Ying Mingyu had already thought very far, and Chen Chen felt that even if he didn't come to help, their speed of solving the case would probably not be too slow.

"Then let's wait until Sister Jin Shi and the others come back tomorrow, let's discuss the deduction?" Chen Chen stretched out and prepared to evacuate.

After all, we have to wait for the results of various inspections. It is rare that everyone has finished the discussion before the clock turns. Next, we still have to continue looking for files. This night, Bao Zhan and Ding Yuan took turns to take a rest. Meili rarely worked overtime at night, so Ying Mingyu

Liu Minmin also rushed back.

After everyone left, Ying Mingyu really wanted to have a late-night snack, but someone was not at home. It would not be good to wake up Chen's mother so late. He and Luo Yin went outside to eat some snacks, but for some reason he felt particularly desolate.

.I wanted to go to the hospital to see Qian Qian, but I was afraid of waking her up and delaying her rest.

After relaxing, they returned to the station and, together with other police officers recruited, continued to search for case information that should have been available a year ago. However, the focus was on the summer vacation in July and August last year.

suspected cases.

On the morning of the 19th, the technology side gave them countless disappointments and a big discovery.

They searched the Internet and found corresponding novels published by four deceased people. After investigation, they were the ones who published it. In addition, they found no traces of other people's theft or plagiarism, and there were no similar readers' comments.

When the persevering technicians checked the forum where Liu Sisi published her novels, they captured an account that frequently left messages. At the same time, they found an account with the same name in the postgraduate entrance examination forum where Ye Xiaojia often visited, and the two had private messages.

After verification by looking for IP and other methods, it was indeed the same person with the same address, and the registration information was that of a male. His real name was also found, his name was Tian Cheng, and he looked pretty good.

"You are so good now?!" Bao Zhan praised people for not being afraid of sore throats, and he was really surprised. In order to find out Chu Lili's address a few years ago, they asked Lu Ju for help and spent a lot of time.

Now the technology department has actually introduced so many high-tech talents.

"Technology is progressing." Technology is very modest.

Chu Lili used a switch at the time, but Tian Cheng did not this time. Moreover, the current technical means have indeed improved, which will be of great help to them in investigating the case.

Ying Mingyu felt that he should really sign up for a computer training class to learn technical things. Now the probability of technological crimes is also increasing, and he can hardly keep up with the times.

"How about we go catch this kid before the deputy team comes back?" Bao Zhan asked the boss for instructions.

Seeing his complacent expression, Ying Mingyu glared at him: "First understand his situation, go meet and ask."

Although there is a particularly convenient way to check Tian Cheng's physical condition, this method is not available for the time being. It may be just a coincidence like Lu Min.

After all, the relationship between him and the other two deceased people has not yet been found, and they still know nothing about this man.

"Master, aren't you going?" Liu Minmin really wanted to make this trip. She thought this Tian Cheng was suspicious.

Ying Mingyu shook his head: "If you want to go with Dingzi and the others, please pay attention to safety."

"Then I won't go, I'll follow you." Liu Minmin responded to the situation, "Master, are you still looking for files?"

"They're looking for it. Let's go to the forensic and trace examination department."

In addition to last year's case files, he also asked people to search for the summer rape and murder cases in the case files from five and six years ago to see if it was possible to push forward the first case.

Because the case this time was initially suspected of being a serial case, more focus was placed on merging old cases and re-investigating them. He had not even gone to see Liu Sisi's autopsy in detail. Because of the physical evidence involved in the trace examination,

Fan Fan, when he and Luo Yin went last time, everyone had no clue.

"How's it going? Do you have any clues about the murder weapon?"

When Ying Mingyu left, Fan Hua had just finished the autopsy on another case and looked at him speechlessly.

"Do you think I'm usually working on that case in your hands from morning to night?" This young man is really temperamental and self-centered.

"So there's still no direction?"

"Isn't this just to give you an opportunity to find Qianqian for personal gain?" Fan Hua didn't want to admit this.

Ying Mingyu rolled his eyes at him. He didn't want to bother his wife yet. Even if he could meet her once, it would cost her a lot of effort, and he would have to show her such a picture, which would affect the pregnancy.

Bao Zhan and Ding Yuan quickly contacted Tian Cheng. He worked as a clerk in a foreign trade company. He studied Chinese language and literature in college and was taking postgraduate entrance examinations while working. He was twenty-six years old and unmarried.

After learning this information, the two people quickly exchanged glances. In some places they were consistent, and in other places they were completely different.

"Can you tell us your itinerary from the 11th to the 13th of this month?"

"It's... normal work and get off work, just like usual."

"Do you live with your family or in a flat?"

"I live alone. What happened?" Tian Cheng was confused.

"Do you have a girlfriend?"

This time Tian Cheng nodded: "Yes, it has nothing to do with her, right? What's wrong with Miaomiao?"

If he is the murderer, he is very good at pretending to be stupid.

"No, do you know Liu Sisi?" Seeing the other party shaking his head, Ding Yuan asked, "What about Ye Xiaojia?"

"We know her. She is my comrade who took the postgraduate entrance examination. Did she pass the examination?"

The two detectives couldn't help but feel sad. Judging from Tian Cheng's reaction, he was still concerned about things that were closely related to him, such as the postgraduate entrance examination, and he did not deny the fact that he knew Ye Xiaojia. This person had drifted away from the murderer.

"Do you mind if we ask about your health, especially in men's medicine?"

Tian Cheng looked embarrassed: "I am in good health... There is no way to ask Miaomiao to have an abortion. We also wanted to have a baby, but we really didn't have the conditions at the time... Aren't we free to choose whether to have children now? You still care about this kind of thing?

?”

"When did it happen? Please provide the name of the hospital so we can verify it."

Ding Yuan, on the principle of doubting everything, still asked for relevant information, and then visited the hospital with Bao Zhan and confirmed that Tian Cheng was not lying.

His girlfriend had an abortion two years ago after getting pregnant, which happened to be around the time Ye Xiaojia was killed. It was obvious that Tian Cheng did not have the hidden disease of the murderer. Not to mention the problem of motive, he could not leave such on-site physical evidence.

When the two of them returned to the bureau dejectedly, Fang Jinshi and Da Zhuang had returned early and were taking a break from reading the case files, waiting for them to discuss together.

Bao Zhan first reported the details of Tian Cheng's exclusion, and then sat down angrily.

This was the second plenary meeting since the investigation started, and Teacher Ji also participated, so everyone reviewed the progress first.

The forensic doctor determined that the four cases could be combined and determined that the murder weapon was of the same type. Trace amounts of residue were extracted from Liu Sisi's wound and were submitted for technical examination. After decomposition, the residue was mainly polyester and some other chemical fiber materials. It was speculated that the murder weapon

It is a rough object such as a woven belt. This special woven belt has not yet been found.

The trace inspection side examined the places where the bodies were dumped, combined with the investigation on the criminal investigation side, and determined that the murderer had a car. Especially in the two cases in other cities: Ye Xiaojia from Meishi City lived in the north of the city, but the body was found in the woods in the south of the city. Even though

The murderer arranged for her to be near the south of the city, and it was impossible to dump the body without transportation. Secondly, in Shantai County, Jinyang City, the body was abandoned in the woods on the road to the countryside. At that time, there was only one person going to the countryside from the city.

It is a short-distance bus and does not stop midway.

The criminal investigation determined that the four deceased people had a hobby of writing novels and published them online. It is possible that the murderer was also a member of the same hobby. After getting to know them through some channels, he lured them out and committed the crime.
