In two days, thanks to the efforts of the police in the city, the investigation of medical and drug-related workers has almost come to an end, but no one who meets the conditions for investigation has been found.

Chen Yi and the others were not disappointed in this matter, the direction was not necessarily correct, at least one possibility could be ruled out.

Early this morning, when Xin also checked all the things that should be checked, and printed out a copy of the information and handed it to Chen Yi.

At this time, Chen Yi was sitting there and reading carefully.

After a long time, he closed the document and handed it to Zhao Qiming beside him.

Looking at Chen Yi's expression, there should be no major discoveries, so Zhao Qiming was not ready to look carefully, flipped through it casually, and said: "Zhu Yulei said that Cao Yuning is an introvert and is not good at communicating, so the Internet should be the most suitable place to obtain information and express emotions." ”

"Didn't you find anything?"

Shi Xin looked over and said, "I can't say that I haven't found anything." ”

"After the death of Cao Yuning's father eight years ago, the text style of all the software and forums under Cao Yuning's name has obviously changed, and all articles about history have been deleted."

"This shows that he switched to psychology, definitely not because he lost interest or anything, according to your previous investigation, he should have received a huge stimulus from Cao Maojun."

"Also, Cao Yuning once published a controversial paper entitled "Academia cannot be a tool for crime."

"Captain Zhao, Team Leader Chen, according to this series of clues, the possibility that Cao Maojun once committed a crime is not low, right?"

Chen Yi didn't speak while thinking about the problem, Zhao Qiming said: "I don't think it's low, Cao Yuning said the word redemption, and also pointed out that Cao Maojun went crazy, although redemption has a variety of meanings in different contexts, but put it here, it should be atonement." ”

"It is not his own sins that are atoned for, but the sins of the father."

"Cao Yuning suddenly changed so much, it can be considered that he knows that the father he has always respected has committed a crime, and the matter is not small."

"Not excluded...... There is a possibility of human life. ”

After speaking, he turned his head to look at Chen Yi, wanting to ask what the other party thought, but found that the latter gave up after pondering.

Shi Xin said: "For this new case, the progress of our investigation is still considerable, but I don't know...... Whether it is highly related to the serial murder case more than ten years ago. ”

"This matter is very important, and it needs to be supported by clues, otherwise it will be troublesome if the case is wrong."

"Two months, but it's going to pass soon."

The last sentence made the attention of everyone present invariably focus on Chen Yi.

The military order was set up by Chen Yi in front of Fang Songping, and his pressure was the greatest.

Seeing that Chen Yi still didn't speak, several people continued to chat.

"Captain Zhao, in fact, I have a stupid way to this new case." When to make a new opening.

Zhao Qiming: "Oh? What's the solution? ”

When is new: "Use the Skynet system to find as much as possible the trajectory of Cao Yuning after leaving the school at the time of the crime, and then radiate to the surroundings according to the trajectory before disappearing, locking all passing vehicles without exception." ”

"Then, we will investigate the nearest surveillance sites around the crime scene, lock on to passing vehicles in the same large area, and then find the overlap point."

Hearing this, Zhao Qiming thought for a while and said: "It's easy to say near the university, and it shouldn't be missed, but the suburbs where the crime occurred are too remote, the murderer is very good at choosing places, and the surrounding roads extend in all directions, so how many cars do you need?" ”

"Moreover, it cannot be ruled out that the murderer is familiar with the local road conditions, and he took the small road to return to the city or even leave Jiangcheng."

"Besides, if there are a lot of overlaps, it is quite difficult to do."

Shi Xin was silent for a while, then nodded: "So I said, this is a stupid way, if there is no major progress in a month...... I'm going to have to try everything. ”

At this time, Chen Yi raised his head slightly and said, "The murderer should not risk doing it in public. ”

The voice sounded, and several people turned their heads, and it turned out that the other party had been listening.

Chen Yi continued: "Cao Yuning's activity trajectory is very simple, it is either home or school, the murderer may have chosen the school from the beginning, or he may have chosen the school after failing to squat near Cao Yuning's house. ”

"If it's a vendetta, Cao Yuning knows something, and the murderer naturally knows it."

"Then, it doesn't sound difficult to use this to deceive Cao Yuning."

"Just imagine, many years later, Cao Yuning would be shocked when someone suddenly mentioned that incident again."

"Doesn't he want to figure it out? Don't want to know who the person in front of you is? ”

"Therefore, in terms of risk and difficulty, it is safer to trick Cao Yuning to the designated place and then do it."

"If I were a murderer, I would definitely do this, make full use of the intelligence advantage to bluff Cao Yuning, at least let Cao Yuning leave with me."

Chen Yi's words made several people nod, and when did they speak: "It makes sense, this is indeed safer and will not be discovered." ”

Chen Yi: "Therefore, the possibility of gaining from monitoring is lower. ”

"But although it's low, you still have to do it, what if the murderer makes a mistake?"

"Let the network supervisor not stop, just come normally, and don't have psychological pressure."

Zhao Qiming nodded: "Okay." ”

Shi Xindao: "By the way, I heard you say that you suspect tomb robbery, if it is tomb robbery, how many possibilities are there?" Is it a murder for the sake of money? ”

Zhao Qiming looked at Chen Yi, and Chen Yi said: "Based on the assumption of the tomb robbery incident, it is certainly possible to make money, but there was no connection between the five victims more than ten years ago, so why did they achieve such unity?" ”

"I don't think about this problem first, just think of it as a temporary unity, or that the victims actually know each other, and then cut off contact and part ways, and because of the long time, Captain Kong didn't find out."

"It's a matter of getting rich."

"The second possibility, if the victims don't know each other, this possibility is more likely."

"The third possibility is that the victim agrees to go to the tomb, and the owner of the tomb is highly related to the murderer, and the murderer thinks that the other party has desecrated the owner of the tomb or is dissatisfied with the loss of family property, and decides to retaliate and kill."

"The fourth possibility, sealing, the murderer was blackmailed by the victim and decided to kill people, but the time interval between killing so many people is fifteen years, it doesn't seem very reasonable."

Several people were silent.

There are too many possibilities to extend a variety of scenarios based on the word tomb robbery, and there are more than these four, and it is impossible to judge which one is more accurate, but can only be used as a reference to verify it according to new clues in the future.

Chen Yi glanced at a few people, and finally set his eyes on Zhao Qiming: "Captain Zhao." ”

Zhao Qiming raised his head: "Team Leader Chen, you say." ”

Chen Yi: "Do we still have anyone who can use it?" ”

Zhao Qiming: "Yes." ”

After speaking, he turned around and shouted: "Pan Cheng!" Come here! ”

"Yes!"

A man walked over quickly, looking about the same age as Zhuo Yun.

"Team Leader Chen, this is the leader of the investigation team of our criminal investigation detachment, Pan Cheng."

Pan Cheng looked at Chen Yi and said rightly: "Team Leader Chen." ”

Chen Yi nodded slightly, and said, "I worked hard to comprehensively investigate the interpersonal relationship between Cao Maojun's father and son. ”

"The focus is on Cao Maojun, see if there is a certain connection between him and the five victims more than ten years ago, check carefully, do you know how to investigate?"

Pan Cheng said loudly: "I know! Friends of friends, relatives of relatives, relatives of friends, friends of relatives, are all in the check! ”

"Also, visit to find out where Cao Maojun has been, what he has done, and look for points of overlap with the five victims."

Chen Yi snorted: "Go ahead." ”

Pan Cheng: "Yes! ”

After Pan Cheng left, Chen Yi smiled: "Captain Zhao, your subordinate is good. ”

Zhao Qiming said with a smile: "Team Leader Chen has won the award, and he will follow me when he joins the company, and I will bring it out." ”

On the other side, "resentment" appeared in Zhuo Yun's eyes: I don't think I'm worse than him, who is from the investigation team?

"Team Leader Chen, next, are we going to investigate the old case more than ten years ago?" Zhao Qiming asked.

Chen Yi nodded: "That's right." ”

"From the murder of Cao Yuning, we have found something unusual, reducing the likelihood of characteristic killings and random killings."

"Then, if the first five victims also have them, it is basically certain that the murderer has a clear purpose for committing the crime, and it is very likely to be a vendetta."

"How are their family statuses checked now?"

Zhao Qiming replied: "It's basically clear, the situation of Sun Jianli and Yao Jing has been determined, and the other three are still visiting." ”

Chen Yi recalled the dossier: "A farmer, a factory laboratory technician. ”

Zhao Qiming: "Yes. ”

Chen Yi took out a cigarette and said, "When it comes to Sun Jianli, his state of death is different from others, and he has obvious external injuries on his body, why do you think this is?" ”

Zhao Qiming had the most say in this, and said: "Before, Master and I thought that the murderer lacked experience and stable mentality in the first crime, which led to problems in the process of committing the crime, which may be a failure of anesthesia, or the victim wakes up halfway. ”

This explanation is reasonable, even if it is a frenzied serial killer, the first crime will inevitably be nervous, leading to mistakes.

Chen Yi nodded slightly: "What if it's based on the assumption of vendetta?" According to our investigation in the past few days, the possibility of vendetta has increased. ”

Zhao Qiming blurted out: "Forced to ask? ”

Chen Yi: "The murderer wanted to kill six or more people, but he didn't know the identities or whereabouts of these people at first, so he could only check, and then he found Sun Jianli first. ”

"After controlling Sun Jianli, I wanted to get the identity or whereabouts of other people through forced questioning, but there was no answer."

"Because if we had an answer, the crime cycle would not have lasted five or even fifteen years."

"If I were a murderer, and my heart was full of grudges that must be washed away by blood, I would like to kill them in one day."

Zhao Qiming agreed: "That's right, if it's a vendetta, Sun Jianli probably went through the process of questioning and didn't ask it, which shows that the five victims really cut off contact, so they couldn't find it back then." ”

"If that's the case, the murderer is a bit powerful, and the police can't find him."

Chen Yi took a puff of cigarette and said, "The time of the crime was fifteen years ago, but the preparation cycle is not necessarily. ”

"If he had started to check twenty years ago or even longer, he would have gotten more information than us, and he would have an innate advantage as a person in the bureau."

Zhao Qiming: "That's the same. ”

Chen Yi: "In any case, Sun Jianli is the first victim of the case, and it needs to be paid attention to. ”

"Let's go for a trip, what's his current family structure?"

Zhao Qiming replied: "My wife has not remarried and has been single, and Sun Jianli already had two sons and a daughter at that time. ”

"The daughter is now married to another place, the younger son is going to college, the eldest son dropped out of junior high school, and later opened a plate processing factory in Fangyi Town, Jiangcheng."

Chen Yi: "How old is the eldest son?" ”

Zhao Qiming: "Thirty-three years old. ”

Chen Yi thought for a while and said, "Sun Jianli had a child at the age of nineteen. ”

Zhao Qiming: "Yes, Sun Jianli graduated from primary school without much education, and got married early. ”

Chen Yi nodded slightly, he knew Sun Jianli's academic qualifications, and there was information in the dossier.

Now that the case has been found here, Sun Jianli's question has come out, if this case is really related to tomb robbery, will an uneducated farmer be involved?

Or did he know one of the victims and brought him with him?

So why can't you find it? I can't find out about 20 years of things...... It's normal.

"Let's go, let's go to Fangyi Town." Chen Yi got up, "This time, Deputy He will also go, bringing the computer." ”

When new: "Okay. ”

Soon, the five people drove the vehicle out of the Jiangcheng City Bureau and rushed to Fangyi Town.

Fangyi Town does not belong to a certain county, and it has long been classified as Jiangcheng, so it is not particularly far from the city, and it can be reached in more than an hour.

On the way, several people didn't talk about the case again,

"Last time I heard Team Leader Chen mention his girlfriend, is she also a police officer?" Zhao Qiming smiled and chatted.

I was also curious about when this matter was new, and I looked at it.

Chen Yi said with a smile: "The forensic doctor of our city bureau is considered ...... Office romance bar. ”

"Forensics?" Zhao Qiming was surprised, "Female forensic doctors are rare now, and in some places, the gender card is relatively dead, and female forensic doctors are not recruited at all." ”

There is definitely a difference between men and women, but it is not sexist, and women may not be able to do jobs that are suitable for men, and vice versa.

Chen Yi: "She...... It's special. ”

Zhao Qiming: "What's special?" ”

Chen Yi: "This ......"

He didn't expect that when he came to Jiangcheng, he would inevitably be gossiped about, and he blamed himself for being idle, and he had nothing to do with Fang Shuyu.

Seeing that Chen Yi didn't want to say more, Zhuo Yun changed the topic: "Team Zhao is married, right?" ”

Zhao Qiming turned his head: "Of course, for sure, the children are all there." ”

Zhuo Yun smiled: "Me too, the child is two years old, what about yours?" ”

Seeing that several people were chatting, Chen Yi did not participate and looked out the window.

Looking at Jiangcheng from the elevated distance, you can only see the community and company buildings in the distance, and the people in it are idle or busy, living in the city peacefully.

Who would have known that a serial murder case that spanned many years would happen next to him.

All you see is light because someone has blocked the darkness.
