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

conference room.

Tang Hongyi brought over the investigation report on the sales invoice case. It was relatively rough, but it had everything it needed.

It was Chen Yi who took the initiative to see it.

Just after Ji Jingfu was found, his whole family died. Whether there is a connection between the two is still unknown. Chen Yi always likes to know more and never misses any details.

Ji Jingfu is a native of Yangcheng. He was a gangster near Xintou Town in the early years. At that time, the security of Xintou Town was still relatively poor, and even the peripheral areas of Hongzhong District were affected. Pornography, gambling and drugs were rampant.

After a severe crackdown, it is gone now.

In other words, Ji Jingfu might have offended someone at that time, but now he suddenly appeared and was targeted by his enemies.

Ji Jingfu had no criminal record and would need to visit a large area to confirm the matter, so there was no problem with Lu Zhengkai's order.

In any homicide case, two things are important.

First, did the murderer leave any directional clues at the scene that can directly identify his identity?

Second, why did the murderer kill the victim.

The motive is there and the identity is there.

"This Ji Jingfu is really a talent."

After reading the investigation report, Chen Yi found no connection between the two cases. However, Ji Jingfu was able to use his brains to earn hundreds of millions with a primary school education. This is not something ordinary people can do.

When it comes to buying and selling invoices, customers are important, confidentiality is important, and operations are also important. Ji Jingfu's business spans nearly thirty provinces, which shows his ability.

How many provinces are there in the country? Almost all over the country.

Thinking about it, even if this person had not embarked on the road of illegal crime, he would have achieved some success in doing business step by step. It is just that it is easier and faster to make money without buying and selling invoices.

Many highly intelligent economic criminals think this way. Although they have the ability to make money, they are unwilling to develop by following the rules. Instead, they choose to go eccentric to gain huge wealth in a short period of time.

Few people can resist the temptation of money. It just depends on whether you are brave enough and have enough brains.

Tang Hongyi said: "His methods are quite rough. We have investigated more serious securities fraud before. He can make tens of millions in a month. If he hadn't been betrayed, we wouldn't even be able to find any evidence."

Chen Yi nodded slightly.

It has to be said that economic crimes are generally more technical than criminal crimes. It is impossible to play economics without thinking.

Criminal crimes are more direct, involving common economic violence, such as robbery and so on.

So as an economic criminal, who can Ji Jingfu offend? Is it because the money is owed and is not being repaid, or is the victim of fraud seeking revenge?

"Team Chen, what do you personally think about this case?" Lu Zhengkai asked as there were fewer people in the conference room.

He would never look down on Chen Yi. His resume was there, and being able to have such prestige in the criminal investigation detachment was not something he could do just by being clever.

Chen Yidao: "It is relatively possible for a person with psychological distortion or lack of personality to commit a crime. The main reason is that the two children were also violated. This is extremely rare in criminal crimes. If it is seeking revenge, there is no reason to do such a despicable thing." Lift.”

Lu Zhengkai: "Pedophilia plus sexual violence?"

Chen Yi: "Yes."

Lu Zhengkai analyzed objectively: "It is indeed very similar to what a pervert did. There is a mixed bag of people in Xintou Town. It cannot be ruled out that the victim, mother and son are being targeted, but we need to find a way to determine whether Ji Jingfu and his wife have any enemies." ”

Chen Yi: "When Ji Jingfu's activities are revealed, it should be helpful for us to further analyze the case."

Um?

The jump was a bit fast. Lu Zhengkai reacted for a while and understood: "What Captain Chen means is to see if Ji Jingfu came back by chance on the day of the crime?

If Ji Jingfu came back by chance, then the suspect's motive for committing the crime has little to do with Ji Jingfu, and the probability of vicious random killing is very high. "

Chen Yi nodded: "Yes, this is the simplest and most direct method. It is more efficient than a comprehensive investigation of Ji Jingfu's interpersonal relationships. We must prevent the possibility that the murderer is a mad dog.

Once there are signs of serial crimes in this case, we will not be able to grasp his crime cycle at all. What if he continues to kill people tomorrow? Even if no one is killed, if a child is harmed, it will be a failure of the task force. "

Lu Zhengkai didn't think that far for the time being, but he agreed with Chen Yi's words. Looking at the history of criminal investigation for decades, as long as the victims were children, the possibility of a series of cases was not low.

Because it is almost impossible for children to form life-and-death feuds with others. There is only one reason for them to be harmed: age.

If a suspect hurts one person, he will hurt the second one sooner or later if he is not caught. Suspects who commit such cases are almost always unstable factors in society. They are either psychologically distorted or mentally ill. In short, they are not normal people.

We chatted until two o'clock in the morning, and the comprehensive autopsy report was delivered. For the time being, it was only for Ji Jingfu and his wife.

Chen Yi and Lu Zhengkai exchanged quick checks.

Ignoring information such as the report number, inspection agency, person submitting the document, and the person being inspected, the two of them turned the page directly to read the key points.

The first is Ji Jingfu’s wife.

Physical examination:

The limbs of the deceased were tied up, with obvious signs of binding, and the skin had minor bruises and strangulation marks caused by long-term binding.

There were no obvious external injuries or defensive wounds on other parts of the body, ruling out the possibility of other violent deaths.

Sexual Assault Examination:

There was obvious trauma to the genital area and lacerations to the inner wall of the vagina, which were consistent with the characteristics of injuries caused by rape.

Samples of the Y tract and surrounding tissue were collected, and DNA analysis found no trace of the stranger. The component analysis showed that it was lubricating oil.

Fatal Injury Check:

There are four obvious cuts on the neck, the wounds are deep into the trachea and esophagus, and the carotid artery ruptures, causing heavy bleeding. The location and depth of the wounds show that the throat was cut as the cause of rapid death, and the vital signs were lost in hemorrhagic shock.

Internal organ examination:

The lungs have less congestion and no hemorrhagic edema, which does not meet the characteristics of death by suffocation.

There are no obvious abnormalities in the heart, and the possibility of death due to heart disease is ruled out.

There are no obvious damage or disease changes in the liver, kidneys and other internal organs.

Below are histological examinations, pathological diagnoses, etc. The total length of the autopsy report is more than ten pages, and the time of death is twenty-six hours.

Very detailed.

The last forensic signature has Su Ying's name. Although she participated in the autopsy process in the middle, her name must be signed, and the responsibility is specific to each person.

Seeing the end, Chen Yi turned back and focused his eyes on one of the lines: No defensive scars were found.

"Willing to be tied up? To protect the child?"

The thought flashed through his mind, and Chen Yi handed the autopsy report to Lu Zhengkai and continued to read Ji Jingfu's autopsy report.

Surface examination:

The deceased's clothes were messy and torn in many places, indicating that he had fought with the murderer before his death.

There were multiple skin abrasions and bruises on the body, concentrated on the limbs and torso, which were consistent with the characteristics of fighting injuries.

There were defensive scars on both hands, and there were fibers of clothing suspected to be the murderer's in the nails, but no skin tissue was seen.

There were four obvious puncture wounds on the front of the chest, with regular shapes and neat edges, indicating that they were caused by sharp objects.

The depth of the wounds varied, and two of them penetrated the chest wall and injured the internal organs.

Internal examination:

There was a puncture wound on the heart, which penetrated the ventricular wall, causing the heart to rupture and bleed profusely.

There were two puncture wounds on the lungs, one of which injured the pulmonary artery and the other injured the lung lobe, causing a lot of bleeding. A large amount of blood accumulated in the chest cavity, and the coagulation state indicated that there was a certain interval between the death times.

There was a puncture wound on the liver, but it did not penetrate, and the amount of bleeding was small.

There was no obvious damage to other organs such as the spleen and kidneys.

There was no sign of poisoning, and the toxicology test result was negative.

Histological examination:

A large number of red blood cells were exuded around the heart and lung wounds, accompanied by neutrophil infiltration, which is consistent with the histological changes of puncture wounds.

Fibrous tissue was broken and a small amount of inflammatory cells were infiltrated at the liver wound.

Conclusion:

The deceased had multiple puncture wounds on the front of the chest, which caused the heart and lung to rupture and bleed heavily, and died 28 hours after death.

Chen Yi put down the autopsy report and said, "Did the woman not resist?"

Lu Zhengkai nodded, "It should be, otherwise the murderer wanted to tie her up and it would be impossible to leave no trace."

No matter how weak a woman is, she is still an adult. Although she can't beat him, it is still very difficult for an adult man to tie up an adult woman if she resists violently, not to mention that the woman has to protect her children, and the energy she explodes must be extremely huge.

At the very least, there must be defensive scars.

But there are none.

This shows that Ji Jingfu's wife is likely to have no resistance, and the reason is also easy to guess. With two children, a mother is easily threatened.

Chen Yi thought about the possibility of an acquaintance, and finally found it difficult to judge, because there are many ways to enter the house, not necessarily knocking on the door, climbing over the wall to find an opportunity to suddenly attack, and using the child as a threat to make Ji Jingfu's wife give up resistance, the probability of success is still very high.

For now, let's wait for the results of the visit and investigation to see if there are any new clues.

Tang Hongyi left the meeting room. The economic investigation needed him to take command and find the connection between the two cases.

The murderer's crime time was a bit too coincidental. It was only one day away from the arrest of the economic investigation. I have to doubt whether there is a causal relationship.

After Tang Hongyi left, several cigarettes were lit, and the smoke soon filled the room.

"The connection between the two cases can actually be thought about more deeply." Chen Yi leaned back in his chair and spoke. He did not think it was a coincidence. "It is not a direct connection, but an indirect connection. The key point is that Ji Jingfu's family packed up and prepared to run away."

Lu Zhengkai: "Captain Chen said that the case of buying and selling invoices has nothing to do with the case of Ji Jingfu's family being killed, but because Tang Zhi's investigation led Ji Jingfu to run away, the suspect took action?"

Chen Yi hummed: "There is such a possibility. It is obvious that the murderer had planned it in advance. As for how long he planned, we have no way of knowing. After discovering that Ji Jingfu's family was about to leave, he knew that he could not wait any longer, so he took action.

As for what Ji Jingfu does and how much money he has, he does not know. The property in his home is intact, which also proves that the murderer is not here for money."

There is no doubt that he only kills people and does not seek money.

In any case, the task force is facing a very dangerous person this time. He will not even let go of children, and will be even more ruthless to the police. He is not much weaker than drug dealers, and there is a possibility that he will fight to the death to resist arrest.

If the identity of the suspect is locked in the future, it is necessary to suppress him with absolute force, and not give the other party any chance to resist.

Zhou Yebin listened for a while, felt that he could not help much, so he left the meeting room. Within 72 hours, he would eat and sleep in the Municipal Bureau like the task force, and set an example.

Qin Fei and others did not leave. They did not receive the notice to join the task force. They were outsiders. They only needed to follow Chen Yi and do whatever Chen Yi told them to do.

The clock in the early morning slowly turned. Chen Yi and Lu Zhengkai continued to analyze the case and opened up more possibilities. At present, new clues were needed to support the evidence, or it would be good to exclude one possibility.

At four o'clock in the morning, Ji Jingfu's driving track was sent. His car was neither a fake nor a fake. It was easy to check with some effort.

At present, the Haiyan second-generation analysis system has not yet been popularized nationwide. It is currently only operating in first-tier cities and some second-tier cities. In the future, once various cities adopt the Haiyan second-generation system, it will not only play a great role in capturing traffic violations, but also provide information to the police. It brings extensive convenience to combating illegal crimes.

What is the Haiyan system? It recognizes thousands of photos per minute and processes up to one million images per day. It not only enables intelligent identification and capture, but also performs secondary analysis on the captured images to provide detailed information, including the vehicle's brand, model, color, Whether there is an annual inspection, what is in the car, whether people are wearing seat belts, whether there are any violations, etc.

Its powerful function lies in its high-precision identification capabilities and wide range of application scenarios. Not only that, it can also learn by itself to identify new and historical models, which greatly enhances the ability to trace violations.

For criminal investigation, this is undoubtedly good news. The suspect will have no way to hide under the Haiyan system.

"No wonder." After getting the scope of Ji Jingfu's daily activities, Lu Zhengkai understood, "He spends the whole day around the branch and the municipal bureau paying attention to the economic investigation's movements, and even followed the economic investigation's car. He must have guessed that he was about to be exposed. So I prepared to run away in advance, but unfortunately I was killed by someone before I could leave Yangcheng from Xintou Town. "

Chen Yi looked at Ji Jingfu's activity track and departure and return time in his hand, and nodded: "He usually comes back at night, but it happened to be early that day. It was early because he was leaving soon and happened to bump into his wife who had just killed him. Son's murderer.

Judging from the autopsy report, Ji Jingfu died at a certain interval. He did not die immediately, which shows that the murderer was still a little panicked. He stabbed him a few times and ran away quickly without confirming whether Ji Jingfu stopped breathing on the spot. "

Lu Zhengkai: "This possibility is very high. The murderer did not expect that Ji Jingfu came home several hours early. It seems that he did not come for Ji Jingfu.

But just in case, Tang Zhi can't stop it for the time being, and the sales invoice case needs to be dug deeper. "

Chen Yi nodded in agreement. Just because Ji Jingfu changed his activity pattern on the day of the crime, he could not determine the murderer's motive. He must be cautious in this matter. Going in the wrong direction will lead to serious deviations in the entire investigation process.

Until the murderer is caught, no one can be sure what he was thinking.

Anyway, the police force is sufficient and full coverage is no problem.

If this case is not solved, the Economic Investigation Detachment will not be able to close the case.

"Team Chen, you go ahead and take a nap for a while, I'll keep an eye on it." Lu Zhengkai said. As the leader of the task force, he has much greater responsibilities and pressure than Chen Yi.

Chen Yi was not pretentious, and Lu Zhengkai also needed time alone: ​​"Then I'll come over in the morning. If you need anything, call me anytime."

There were still two autopsy reports yet to come out, so the special case team waited until after six in the morning, and then left the city bureau with Su Ying.

You don't need to read the report, just listen to what Su Ying says.

On the way back, Su Ying focused on the important points.

There are differences between the two young victims and Ji Jingfu's wife. The biggest difference is that they were abused before death. There are inconspicuous pinch marks on their necks, indicating that the murderer either strangled the victims to death or simply abused them.

The fatal injury still came from cutting the throat.

The amount of bleeding was not large, and the cause of death was determined to be suffocation based on severe edema in both lungs and severed trachea.

Time of death twenty-eight hours.

Four lives, two ways of killing, and three causes of death further confirmed that the perpetrator was a novice.

A novice who can commit such inhumane killing must not be a normal person. Chen Yi had a hunch that if this guy was not caught as soon as possible, something would probably happen.
