Detective: Open your eyes, I am handcuffed in the interrogation room

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

Regarding this matter, Chen Yi and others were not disappointed. The direction was not necessarily correct in the first place, and at least one possibility could be eliminated.

Early this morning, Shi Xin also checked everything that needed to be checked, printed out a copy of the information, and gave it to Chen Yi.

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

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

Judging from Chen Yi's expression, there should be no major discoveries, so Zhao Qiming was not prepared to take a closer look. He flipped through it and said: "Zhu Yulei said that Cao Yuning is an introvert and not good at communication, so the Internet should be the best place to obtain it. A place for information and expression of emotions.”

"Did you find anything?"

He Xin looked over and said, "I can't say that I didn't find anything."

"After the death of Cao Yuning's father eight years ago, the writing style of all software and forum accounts 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 huge stimulation from Cao Maojun."

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

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

Chen Yi was thinking about the problem and did not speak. Zhao Qiming said: "I think it's not low. Cao Yuning even said the word redemption, and also pointed out that Cao Maojun went crazy. Although redemption has multiple meanings in different contexts, Putting it here should be atonement."

“The atonement is not for your own sins, but for the sins of your father.”

"Cao Yuning suddenly experienced such a big change. It is completely believed that he knew that his father, whom he had always respected, had committed a crime, and the matter was not small."

"We cannot rule out the possibility that... a human life may have been lost."

After saying that, he turned to look at Chen Yi, wanting to ask what he thought, but he gave up after finding that the latter was deep in thought.

Shi Xindao: "For this new case, our investigation progress is still considerable, but we don't know... whether it is highly related to the serial murder case more than ten years ago."

"This matter is very important and needs clues to support it. Otherwise, it will be troublesome if the case is merged and investigated incorrectly."

"Two months, but it will pass quickly."

The last sentence made everyone present focus on Chen Yi.

Chen Yi issued the military order in front of Fang Songping, so he was under the greatest pressure.

Seeing that Chen Yi still didn't speak, the others continued chatting.

"Captain Zhao, actually I have a stupid idea for this new case." He Xin spoke.

Zhao Qiming: "Oh? What can I do?"

When is new: "Use the Skynet system to find as much as possible the trajectory of Cao Yuning after he left the school when the incident occurred, and then radiate to the surroundings based on the trajectory before disappearing, locking all passing vehicles without exception."

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

Hearing this, Zhao Qiming thought for a while and said: "It's easy to say that it's near the university. I shouldn't miss it, but the suburb where the crime occurred is too remote. The murderer is very good at choosing places. The surrounding roads extend in all directions. How many cars will it take?"

"Moreover, we cannot rule out the possibility that the murderer was familiar with the local road conditions and took a small road back to the city or even left Jiangcheng."

"Furthermore, if there are many overlapping points, it will be quite difficult to handle."

Ji Xin was silent for a while, then nodded and said: "So I say, this is a stupid way. If there is no significant progress within a month... we must try any method."

At this time, Chen Yi raised his head slightly and said, "The murderer probably wouldn't risk doing it in public."

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

Chen Yi continued: "The trajectory of Cao Yuning's activities is very simple. He is either home or school. The murderer may have chosen school from the beginning, or he may have chosen school instead after failing to squat near Cao Yuning's home."

"If it was a vendetta, Cao Yuning knew something, and the murderer naturally knew it too."

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

"Imagine how shocked Cao Yuning would be many years later when someone suddenly mentioned that incident again."

"Doesn't he want to find out? Doesn't he want to know who the person in front of him is?"

"Therefore, in terms of risk and difficulty, it is safer to deceive Cao Yuning into a designated location before taking action."

"If I were the murderer, I would definitely do this. I would make full use of my intelligence advantages to scare Cao Yuning. At the very least, I could make Cao Yuning leave with me."

Chen Yi's words made a few people nod. He Xin said, "It makes sense. This is indeed safer and will not be discovered."

Chen Yi: "So, the possibility of harvesting results from monitoring surveillance is even lower."

"But even though it's low, it still needs to be done. What if the murderer makes a mistake?"

"Ask the network supervisor not to stop, just do it normally and don't feel any psychological pressure."

Zhao Qiming nodded: "Okay."

Shi Xin said: "By the way, I heard that you suspect tomb robbing. If it is tomb robbing, what are the possibilities? Is it to kill people and get goods for profit?"

Zhao Qiming looked at Chen Yi, and Chen Yi said: "Based on the hypothesis of the tomb robbery incident, it is certainly possible to get money for money, but there is no connection between the five victims more than ten years ago. How can they be so united?"

"Let's not think about this problem for now, just think of it as a temporary unity, or that the victims actually knew each other, but later cut off contact and parted ways, and because of the long time, Captain Kong did not find out."

"This is motivated by wealth."

"The second possibility is to see death without saving anything. If the victims don't know each other, this possibility is relatively high."

"The third possibility is that the victim agreed to go to the grave, and the owner of the tomb and the murderer were highly related. The murderer believed that the other party had desecrated the owner of the tomb or was dissatisfied with the loss of family property, and decided to kill in revenge."

"The fourth possibility is to keep the secret secret. The murderer was blackmailed by the victim and decided to kill people to silence him. But it seems unreasonable to kill so many people fifteen years apart."

Several people were silent.

There are too many possibilities to extend multiple scenarios based on the word "grave robbery", and there are more than just these four. Moreover, it is impossible to judge which one is more accurate. It can only be used as a reference to verify based on new clues in the future.

Chen Yi glanced at several people and finally focused on Zhao Qiming: "Captain Zhao."

Zhao Qiming raised his head: "Team Leader Chen, please tell me."

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

Zhao Qiming: "Yes."

After saying that, he turned around and shouted: "Pan Cheng! Come here!"

"yes!"

A man walked over quickly and looked to be about the same age as Zhuo Yun.

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

Pan Cheng looked at Chen Yi, stood at attention and said, "Team Leader Chen."

Chen Yi nodded slightly and said: "Thank you for your hard work to comprehensively investigate the interpersonal relationship between Cao Maojun and his son."

"The focus is on Cao Maojun. Let's see if there is any connection between him and the five victims more than ten years ago. Check carefully. Do you know how to check?"

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

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

Chen Yi hummed: "Go ahead."

Pan Cheng: "Yes!"

After Pan Cheng left, Chen Yi smiled: "Captain Zhao, you are a good subordinate."

Zhao Qiming said with a smile: "Team Leader Chen has been praised. He will follow me when he joins the company. I brought him out."

On the other side, Zhuo Yun's eyes showed "gloomy resentment": I feel that I am no worse than him. We are all members of the investigation team, who obeys whom?

"Team Leader Chen, next, are we going to investigate old cases from 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, which reduces the possibility of characteristic killing and random killing."

"Then, if there are also the first five victims, it can be basically confirmed that the murderer had a clear purpose in committing the crime, and it is most likely a vendetta."

"How is their family situation being investigated now?"

Zhao Qiming replied: "We have basically found out. The conditions of Sun Jianli and Yao Jing have been determined, and the other three are still being visited."

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

Zhao Qiming: "Yes."

Chen Yi took out a cigarette and said: "When it comes to Sun Jianli, his death state is different from other people's. There are obvious traumas on his body. Why do you think this is?"

Zhao Qiming had the most say on this, and said: "Master and I previously believed that the first murderer lacked experience and a stable mentality, which led to problems during the crime. It may be that the anesthesia failed, or the victim woke up midway."

This explanation is reasonable. Even if it is a crazy serial killer, he will inevitably be nervous when he commits the first crime, which will lead to mistakes.

Chen Yi nodded slightly: "What if it is based on the hypothesis of vendetta? According to our investigations in the past few days, the possibility of vendetta has been increased."

Zhao Qiming blurted out: "Force me?"

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 had to check, and then he found Sun Jianli first."

"After taking control of Sun Jianli, I tried to get the identity or whereabouts of other people through questioning, but there was no answer."

"Because if the answer is obtained, the crime cycle will not last five or even fifteen years."

"If I were a murderer and my heart was filled with hatred that could only be washed away with blood, I would wish to kill him in one day."

Zhao Qiming agreed: "Yes, if it was a vendetta, Sun Jianli probably went through the process of interrogation and did not ask. This shows that the five victims really cut off contact, so they could not be traced back then."

"If this is the case, the murderer is quite powerful. He was able to find him even though the police couldn't."

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

"If he started investigating twenty years ago or even longer, he would naturally be able to obtain more information than us, and he would have an inherent advantage as a person in the game."

Zhao Qiming: "That's true."

Chen Yi: "Anyway, Sun Jianli is the first victim of the case and needs to be focused on."

"Let's go take a look. What's his current family structure like?"

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

"The daughter is now married out of town, the younger son is in college, and 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 has a child when he is nineteen."

Zhao Qiming: "Yes, Sun Jianli graduated from elementary school with little education and got married relatively early."

Chen Yi nodded slightly. He knew Sun Jianli's academic qualifications and there was information in the file.

Now that the case has been investigated, Sun Jianli's question arises. If the case is really related to tomb robbing, will an uneducated farmer be involved?

Or did he know a certain victim and brought him there by the way?

So why can't it be found? It's normal to not be able to find out things that happened around twenty years ago...

"Let's go to Fangyi Town." Chen Yi stood up, "Deputy He is also going this time, bringing his computer."

When is new: "Okay."

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

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

On the way, few people stopped talking about the case.

"Last time I heard Team Leader Chen mention his girlfriend, is she also a policeman?" Zhao Qiming said with a smile.

I was curious when this happened, so I looked over.

Chen Yi smiled and said: "Our city bureau's forensic doctor is...an office romance."

"Forensic doctor?" Zhao Qiming was surprised. "Female forensic doctors are rare nowadays. Some places have very strict gender restrictions and do not recruit female forensic doctors at all."

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

Chen Yi: "She...is quite special."

Zhao Qiming: "What's so special about it?"

Chen Yi: "This..."

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

Seeing that Chen Yi was unwilling to say more, Zhuo Yun changed the subject: "Is Captain Zhao married?"

Zhao Qiming turned around: "Of course, for sure, we have children."

Zhuo Yun smiled and said: "Me too, the child is two years old, where is yours?"

Seeing a few people chatting, Chen Yi did not participate and looked out the window.

Looking at Jiangcheng from the elevated road, all that can be seen are residential communities and company buildings in the distance. The people inside are either idle or busy, living peacefully in this city.

Who would have known that a serial murder case spanning many years would happen right next to them.

All you see is light because someone blocks the darkness.
