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

Chapter 139 Various Hypotheses
"Come in first."

Kong Hanyong and Chen Yi were unfamiliar, but he didn't ask any more questions for the time being and retreated to the room to signal a few people to come in.

After the door closed, everyone came to the living room.

There are tea-drinking utensils on the coffee table, which are very exquisite. It seems that Kong Hanyong usually only drinks tea, waters flowers, walks and so on.

Regarding the criminal investigation, there are only memories left.

After several people sat down, Kong Hanyong asked: "Are these three new police officers from the detachment?"

Chen Yi, Zhuo Yun and Qin Fei all look younger.

Zhao Qiming explained: "It's not Master, they are from the Yangcheng Criminal Investigation Detachment."

"This is the deputy captain of the Yangcheng City Bureau's criminal investigation detachment, and is now the leader of the Jiangcheng task force."

Hearing this, Kong Hanyong was stunned for a moment, a little surprised, and couldn't help but look at Chen Yi: "Such a young deputy detachment leader is rare and amazing. It seems that he has outstanding abilities and was valued by the provincial department and promoted. "

"What case did you say about the task force just now? Are there any big cases in Jiangcheng recently?"

"Oh...if it involves case confidentiality, you don't need to tell me, I'm just asking casually."

Zhao Qiming was silent for a while and said: "Master, Team Leader Chen came to see you specifically this time."

"Huh? Looking for me specifically?"

Kong Hanyong was surprised and looked at Chen Yi again.

I'm an old detective with nothing to do. Why would you want to find me when you have nothing to do?
The next moment, he seemed to think of a possibility, and his face immediately froze.

"Then...that person appeared again??"

It could be heard that there was a tremor in Kong Hanyong's voice.

Zhao Qiming nodded.

After receiving the affirmation, Kong Hanyong's face changed drastically, he stood up suddenly, looked at Zhao Qiming in front of him in surprise, and then turned to look at Chen Yi, who had not spoken yet.

"Same modus operandi?"

Zhao Qiming nodded again.

"The one who died...was a middle-aged man?"

Zhao Qiming continued to nod.

Kong Hanyong took a deep breath, clenched his hands tightly, and the muscles on his face were trembling.

This case was the last case he was responsible for in his career. It was also the most serious murder case and the only unsolved case.

He tried his best to investigate for several years, but the progress of the case was extremely slow, and the murderer was not even seen.

Except for his gender, which was most likely male, he had no other characteristics. The dead kept appearing, and he resigned because of this.

I don’t know if it was a coincidence or not, but just after he resigned, the murderer stopped killing people and disappeared since then.

Unexpectedly, ten years later, just when he thought the murderer would be at large, he would appear again.

Should I be happy, sad, or angry?
As a former detective, he definitely couldn't be happy. After all, a new victim had appeared.

But the emergence of new cases means that the murderer is on the move again.

As long as he moves, there will be new clues, and the probability of catching him will increase.

Therefore, Kong Hanyong's mood at the moment is extremely complicated.

"Master, please don't get excited. Sit down and let's talk slowly." Zhao Qiming said quickly.

Kong Hanyong stood there for a while, and then slowly sat back down. He wanted to take out a cigarette out of habit, but found that he had already quit.

Seeing this, Zhao Qiming took out the cigarette case and handed it over: "Master, haven't you quit smoking?"

Kong Hanyong glanced at the cigarette case handed over by Zhao Qiming, waved his hand to refuse, and then looked at Chen Yi.

"Team Leader Chen, you are young and promising."

Ten years later, the case happened again. This time, the person responsible for the investigation was not the Criminal Investigation Detachment of Jiangcheng City Bureau, but a task force sent by the provincial department.

For such a big case, the provincial department can safely hand it over to the young man in front of him, which indirectly shows that the other party is not simple.

Chen Yi said: "Hello, Captain Kong, this case...can we talk about it?"

Kong Hanyong leaned on the sofa, with memories in his eyes: "You came to me immediately. Are Team Leader Chen sure that the murderer is the same person?"

Chen Yi said: "This is the greatest possibility. Even if they are not the same person, the two cases must be connected, right?"

Hearing this, Kong Hanyong nodded slightly: "You are right."

"Who died this time?"

Chen Yi roughly shared Cao Yuning's personal information with Kong Hanyong, including the entire process of the other party's murder.

After listening, Kong Hanyong looked solemn: "Have you already started killing university professors? What on earth is this guy going to do?"

"Team Leader Chen, you said that the victim walked out of college on his own. Have you checked? Why did he walk out of college?"

Chen Yi nodded and said: "We checked. After confirming the identity of the deceased the day before yesterday, Captain Zhao immediately arranged for the police to visit Jiangcheng University. They also retrieved surveillance and mobile phone call records. At the same time, they investigated and restored the chat records, but did not get the reason. ."

"I think it was a coincidence that the day he walked out of school alone was the time of his death."

These words made Kong Hanyong excited: "The murderer must be on guard!"

"Team Leader Chen, investigate quickly!"

"Search all doctors, nurses, and pharmaceutical company employees in the city who have absence records. Don't let go of anyone who has close contact with medical anesthetics!"

He seemed to see the hope of solving the case and was a little excited.

Zhao Qiming looked at Chen Yi. This was indeed a good direction for investigation.

Chen Yi nodded slightly: "Captain Kong is indeed an old detective. His words are on point. I am about to do this."

"The murderer always chooses anesthetics as an auxiliary killing tool. It should not be difficult for him to obtain them. However, Captain Kong has conducted a comprehensive investigation, and this matter is still a doubtful point."

"It's definitely impossible to buy something with a real name. It can only be done through indirect means, such as theft and private transactions."

"Captain Kong, if the murderer uses money to lure him and buys it from the doctor, do you think it's feasible?"

Kong Hanyong frowned: "The hospital was a key investigation site back then. I believe I have investigated it very carefully. Even if it was sold privately, there would be no trace at all."

"Unless the murderer bribes all the purchasers, warehouse managers, and doctors, and these people have very good acting skills, I think it is unlikely."

"To spend so much effort on some anesthetics and increase the risk of exposing yourself is not something this guy can do."

"If you go to a place far away from Jiangcheng to buy... it will be even more difficult. You are not familiar with the place. Narcotics are strictly controlled by the state. No one will take the risk of committing a crime just for a little money."

Chen Yi: "So, you still think that the murderer should have access to these anesthetics, at least it is relatively easy to obtain them."

Kong Hanyong nodded: "Yes, it must be easier."

"Otherwise, he could have chosen other methods to make the victim lose the ability to resist, not just anesthetics."

Chen Yi pondered for a moment, then turned to look at Zhao Qiming: "Captain Zhao, after returning to the city bureau, notify all police stations and sub-bureaus in the city, and dispatch police forces to visit all clinics, hospitals, veterinary clinics, veterinary hospitals, and pharmaceutical companies in the jurisdiction. Pharmaceutical manufacturing factories, etc.”

"As long as an employee is found to have been absent from work for a long time before the incident, regardless of the reason for the absence, he will be brought back immediately."

Zhao Qiming: "Okay, I understand."

Kong Hanyong glanced at Chen Yi, this guy is decisive and has a leadership style.

Chen Yi continued: "Captain Kong, let's talk about the commonalities between the five victims more than ten years ago."

Mentioning this matter, Kong Hanyong shook his head helplessly: "Unfortunately, there are only two things I know in common: male and middle-aged."

"Others, nothing was found."

"I've checked everything about family similarities, common events, places I've been to at the same time, etc., and there's nothing."

"To this day, I still can't figure out how the murderer chose the target of the crime."

"You call it a vendetta, there is no connection between the dead."

"If you want to say random killing, the gender and age of the deceased are highly similar."

"If you kill people based on characteristics, what are these characteristics? I definitely don't believe it's just because of middle-aged men."

"Taking a step back, even middle-aged men should have more detailed characteristics, such as personality traits."

"But have you seen, Team Leader Chen, that now there is a university professor? The family backgrounds, education, occupations, personalities, and experiences of these six people are all different. This... this is really incredible."

Listening to Kong Hanyong's words, Chen Yi could feel the other party's powerlessness. No matter how he checked, there was no clue.

"Perhaps... the common ground is hidden very deep and the time span is very long, so we can't find it?" he said.

Kong Hanyong: "I've thought about this, and I can only explain it this way."

"If they knew each other 20, 30, or even 40 years ago, and then became strangers for some special reason, it would be impossible to find out, it would take too long." "Team Leader Chen, if you still insist on tracing If there are commonalities, I think we should start from other aspects, and the time span should not be too long, otherwise it will be half the result with twice the effort, and in the end it will most likely be wasted effort."

"This guy, I don't know when he will do it again."

Chen Yi nodded: "Captain Kong, don't worry, I know what's going on."

"In fact, you have already investigated this case comprehensively. There is not much I can do. At present, the common points are that on the one hand, the murderer's method of committing the crime is... on the other hand."

Hearing this, Kong Hanyong was a little surprised: "You want to find out the murderer's motive based on the way he committed the crime?"

"Rely on what?"

Chen Yi: "Criminal Psychology."

These five words made Kong Hanyong silent for a while, and then he sighed: "My master didn't teach me this stuff back then. He told me that visible clues are always the most important. All evidence speaks for itself and everything is spoken on the spot. "

"But what should we do if there are no clues and no evidence?"

"Team Leader Chen, you are a new generation of criminal police officers with richer knowledge, better skills, and more avant-garde ideas. I believe you can do it."

"But since you mentioned it, I still want to hear it."

Chen Yi nodded: "I also want to communicate with Captain Kong, because you are the only one who is most familiar with this case."

Kong Hanyong did not deny it.

If his familiarity with the case was second to none, then only the murderer would dare to be first.

Chen Yi: "Captain Kong, there are two ways to analyze the murderer's motive based on the way he committed the crime."

"The first is to push forward based on assumptions, and the second is to push back based on results. Both methods are acceptable. I am personally more accustomed to the first method."

"Let's assume the murderer has antisocial personality disorder."

"This type of personality disorder is the type with the most serious impact on society. It is characterized by high aggression, lack of shame, and behavior that is completely driven by motivation and cannot be controlled."

"If this is the case, we have to consider the factors that formed the murderer's personality. Generally speaking, there are three types."

"First, the family's growing environment is not good."

"Second, the improper education methods of parents."

"Third, I suffered severe physical and mental setbacks while growing up."

"We tentatively believe that the murderer had all three qualities at the same time, which led him to hate society and begin to vent his anger."

"Then why did he choose to bury the victim in the soil, hit him with a shovel, and place a mirror in front of the victim?"

"There are always explanations for strange behaviors, which come from his early psychological growth. For example, he was abused in this way and had to use the same way to vent his anger."

"What do you think, Captain Kong?"

Kong Hanyong thought about it seriously and nodded: "It's more reasonable."

"The murderer was buried in the ground by his parents when he was a child, or was bullied by his friends when he was growing up. The despair of being controlled by a cage and the feeling of dying had a great negative impact on his psychology."

"But if that's the case, there shouldn't be a ten-year period of silence. Killing is addictive, and the frequency of his crimes will only get higher and higher, rather than ending suddenly."

"Besides, the targets of the crime are not all middle-aged men, right? And there is also a Sanda coach among them, so the risk is too great."

Chen Yi: "Yes, this is another issue, let's not consider it for now."

"Now we think about the second hypothesis."

"It is assumed that the murderer has a serious psychological distortion, and the inducement comes from his father, adoptive father, or uncles and uncles, all of whom are middle-aged men."

"Among this group of people, the murderer was brutally tortured, leading to severe psychological distortions and hatred for middle-aged men with the same triggers."

“He was afraid of the triggers and didn’t dare to face them, so he vented his hatred on others.

"He hates anyone who is a middle-aged man."

"In this case, what kind of psychology did he use to commit crimes by burying people under a microscope?"

"I think it's either the same as the first hypothesis, or it was inspired by media such as television."

"The third hypothesis is that the murderer has a histrionic personality disorder and kills for fun and for show."

"The strange method of committing crimes is the way he performs. The motivation for his behavior comes from external inspiration, self-creation or the real audience he expects."

"The real audience mentioned here is the main cause of his personality disorder."

"The fourth hypothesis is that the murderer was seeking revenge. This possibility is relatively small now because the five victims from more than ten years ago cannot find any connection with each other."

"Although the probability is relatively small, it exists theoretically. For example, five victims came together by fate in their early years, including the murderer or someone related to the murderer."

"We don't have to guess what happened. It's meaningless. The result is that the murderer or people related to the murderer were harmed. This harm may be profit harm or personal harm."

"If it is an injury to interests, this sixth person is the murderer. If it is personal injury, such as death, this sixth person is a person related to the murderer. The murderer in this case is seeking revenge for others."

"Based on the murderer's special modus operandi, I believe that personal injury is more likely than profit injury, much higher."

"For example, the persons related to the murderer died at the hands of five people in the same or similar manner to the modus operandi of this case. Later, the murderer used the same or similar method to kill all the participants in order to take revenge."

Hearing this, Zhao Qiming glanced at Chen Yi. He now seemed to understand why the other party could solve murder cases repeatedly and was promoted rapidly in one year.

"What do you think, Captain Kong?" Chen Yi finally spoke.

Kong Hanyong thought for a long time this time and said, "Are there any other hypotheses?"

Chen Yi: "Yes, the murderer is a normal person, a madman with high IQ. In order to seek excitement, he chose a personal favorite way of killing to satisfy himself and provoke the police."

"He doesn't kill women, only men. Maybe he doesn't bother to attack vulnerable groups and is looking forward to a challenge."

Kong Hanyong: "This situation sounds unlikely. Which hypothesis does Captain Chen think is most consistent with the characteristics of this case?"

Chen Yi shook his head: "I can't answer this question now, I need more clues."

"If you really want to say it, it is the second and fourth types. The murderer will not choose all middle-aged male victims for no reason."

"And you just said that there is a Sanda coach among the victims, so there is a high risk."

"If you can find a connection between the victims, it's a vendetta. If you can't, it's not."

Kong Hanyong took a deep breath and said: "Although I feel that it is not helpful in investigating the case, the strange thing is that after listening to what you said, I seem to have seen the general outline of this case, but it is not very clear."

"As long as clues are filled in, even if there are only one or two, there will be a major breakthrough in the case."

"Experts from the provincial department also said similar things more than ten years ago, but they were not as detailed as you. For this reason, I also specifically checked the adoptive families and orphans, but there was no result."

"It's just these ten years of silence...why?"

Chen Yi said: "If it is the second hypothesis, the crime will not stop. The murderer may have encountered something that healed his soul, such as falling in love, getting married, having a child, etc., or he has lost the ability to commit crimes, such as being injured or imprisoned."

"If it is the fourth hypothesis, then it can only be that he has lost the ability to commit crimes or is investigating the person."

"Searching for people?" Kong Hanyong caught these two words keenly, "Searching for whom?"

Chen Yi looked at Kong Hanyong strangely: "Of course it is to find the enemy. It has been assumed that the five people are strangers. Even if he finds one of them and interrogates the identities of the others, there may not be a clear result. He can only check."

"Jiangcheng is big, Dongzhou is big, the country is big, and the world is big. Ten years is not long. It is possible to search for a lifetime in the vast sea of ​​people."

Kong Hanyong nodded: "Oh, I understand."

"Then Team Leader Chen thinks this new case can be regarded as...a breakthrough?"

Chen Yi: "Not necessarily."

"Although technology is developing and surveillance is becoming more and more perfect, the corresponding killers are also growing."

"If it's the same person, I don't think he can leave any clues for investigation in this case."

"The only thing that is good for us is that we have one more subject to investigate and new interpersonal relationships. After in-depth understanding, we may be able to gain unexpected results."

Kong Hanyong: “So what is Team Leader Chen’s next direction?”

Chen Yi: "First check the deceased in the new case to determine if he has known any unrelated people in the recent period and his past."

"Then, reopen the investigation of the case from 15 years ago and try to find common ground."

The last sentence made Kong Hanyong hesitate: "But... we have already..."

Chen Yi hesitated for a moment and said, "Captain Kong, just because you didn't find it back then doesn't mean it wasn't there."

These words made Zhao Qiming's face change slightly, and then he sighed.

Kong Hanyong's body was also shaken.

It's a bit harsh, but it's probably true.

"I'm sorry." Chen Yi nodded slightly.

Kong Hanyong shook his head: "Nothing, Team Leader Chen, is there anything I can do to help you?"
