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

Chapter 636 Autopsy Report
meeting room.

Tang Hongyi brought the investigation report on the invoice trading case. It was rather rough, but contained everything it should have.

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

As soon as Ji Jingfu was found, his entire family died. Whether there is any connection between the two is still an unknown. Chen Yi always likes to know more and does not miss any details.

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

After the severe crackdown, it no longer exists.

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

Ji Jingfu had no criminal record, and to confirm this matter would require extensive visits, so there was no problem with Lu Zhengkai's order.

In any homicide case, two things are important.

First, did the murderer leave any clues at the scene that could directly identify the murderer?

Second, why did the murderer kill the victim?

With motivation, there is identity.

"This Ji Jingfu is really a talented person."

After reading the investigation report, Chen Yi did not find any connection between the two cases. However, Ji Jingfu was able to make hundreds of millions of dollars with his brain with only an elementary school education, which is not something that ordinary people can do.

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

How many provinces are there in the country? They are almost everywhere in the country.

I think that even if this person had not embarked on the path of breaking the law and committing crimes, he would have achieved some success by doing business step by step. It's just that it's not as easy and quick to make money as buying and selling invoices.

Many high-IQ economic criminals have this kind of thinking. They are clearly capable of making money, but they are unwilling to develop in an ordinary way. Instead, they choose to take unconventional measures to gain huge wealth in a short period of time.

Few people can resist the temptation of money. It depends on how brave and smart you are.

Tang Hongyi said: "His methods are relatively crude. We have investigated more serious cases before, such as securities fraud, which can make tens of millions in a month. If it weren't for someone selling it, we wouldn't even be able to find evidence."

Chen Yi nodded slightly.

It has to be said that economic crimes, in general, are more technically demanding than criminal crimes, and you can't play economics without thinking.

Criminal offenses are more direct and involve common economic violence, such as robbery and so on.

As an economic criminal, who could Ji Jingfu offend? Someone who owed him money and refused to pay it back, or a fraud victim who came to seek revenge?
"Captain Chen, what do you personally think about this case?" As the meeting room became less crowded, Lu Zhengkai asked.

He would never look down on Chen Yi. His resume was there, and he couldn't achieve such prestige in the Criminal Investigation Detachment by being clever.

Chen Yidao: "It is relatively likely that the crime was committed by someone with a twisted mind or personality disorder. The main reason is that the two children were also violated, which is extremely rare in criminal cases. If it was revenge, there is no reason to do such a despicable act."

Lu Zhengkai: "Pedophilia plus sexual violence?"

Chen Yi: "Yes."

Lu Zhengkai made an objective analysis: "It does look like something a pervert would have done. Xintou Town is a hodgepodge of people. It is possible that the victim and her two children were targeted by someone, but we need to find a way to determine whether Ji Jingfu and his wife have any enemies."

Chen Yi: "Once Ji Jingfu's activity trajectory is revealed, it should be helpful for us to further analyze the case."

Ok?
The jump was a bit too fast, and Lu Zhengkai took a while to react and understood: "Captain Chen's meaning is to see if Ji Jingfu happened to come back on the day of the incident?

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

Chen Yi nodded: "Yes, this is the simplest and most direct way. 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.

If this case shows signs of serial crime, we will not be able to grasp his crime cycle at all. What if he continues to kill tomorrow? Even if he does not kill anyone, if another child is hurt, it will be a failure for the task force. "

Lu Zhengkai didn't think that far for the time being, but he agreed with Chen Yi. Looking at the history of criminal investigation over the past few 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 have a life-and-death feud with others, there is only one reason why they get hurt: their age.

If a suspect hurts one person and is not caught, he will sooner or later hurt a second person. Suspects who commit such crimes are almost always social instability factors, either mentally twisted or mentally ill, in short, they are not normal people.

As they were chatting, it was two o'clock in the morning when the comprehensive autopsy report was delivered. For the time being, it only included the autopsy reports of Ji Jingfu and his wife.

Chen Yi and Lu Zhengkai exchanged quick glances.

Skipping over information such as the report number, inspection agency, person submitting the inspection, and person being inspected, the two turned the pages directly to look at the key points.

First is Ji Jingfu’s wife.

Physical examination:
The deceased's limbs were tied up, with obvious signs of binding, and his skin had slight bruises and marks from being tied up for a long time.

No obvious external injuries or defensive wounds were found on other parts of the body, and the possibility of other violent causes of death was ruled out.

Sexual Assault Examination:
There were obvious external injuries to the vagina and lacerations on the inner wall of the vagina, which were consistent with the characteristics of injuries caused by rape.

Samples were collected from the vagina and surrounding tissues, and DNA analysis revealed no traces of strangers, while component analysis revealed lubricating oil.

Fatal injury check:
There were four obvious cuts on the neck, the wounds were deep into the trachea and esophagus, and the rupture of the carotid artery caused heavy bleeding. Analysis of the location and depth of the wounds showed that cutting the throat was the rapid cause of death, and the patient lost vital signs in hemorrhagic shock.

Internal organ examination:
There was little congestion in both lungs and no hemorrhagic edema, which did not meet the characteristics of death from asphyxiation.

There were no obvious abnormalities in the heart, ruling out the possibility of death from heart disease.

No obvious damage or disease changes were found in the liver, kidneys and other internal organs.

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

Very detailed.

Su Ying's name was included in the final forensic signature. Although she only participated in the autopsy process halfway, her name had to be signed, and the responsibility was specific to each person.

After reading to the end, Chen Yi flipped back and fixed his eyes on a line of words: No defensive scars were found.

"You were willing to be kidnapped? 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.

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

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

There were defensive wounds on both hands, and fibers of clothing suspected to be the murderer's remained under the fingernails, but no skin tissue was seen.

There were four obvious stab wounds on the front of the chest, with regular shapes and neat edges, indicating that they were caused by a sharp object. The depth of the wounds varied, and two of them penetrated the chest wall and injured internal organs.

Internal inspection:
There was a puncture wound in the heart that penetrated the ventricular wall, causing the heart to rupture and cause massive bleeding.

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

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

No obvious damage was found to other organs such as the spleen and kidneys.

There were no signs of poisoning and the toxicology test results were negative.

Histological examination:
A large amount of red blood cell infiltration was seen around the heart and lung wounds, accompanied by neutrophil infiltration, which was consistent with the histological changes of puncture wounds.

Fibrous tissue rupture and a small amount of inflammatory cell infiltration were observed at the liver wound.

in conclusion:

The deceased had multiple stab wounds on the front of his chest, which caused rupture of his heart and lungs and massive bleeding, and he died within 28 hours of death.

Chen Yi put down the autopsy report and said, "The woman didn't resist?"

Lu Zhengkai nodded: "That should be the case, otherwise the murderer couldn't have tied her up without leaving any traces."

No matter how weak a woman is, she is still an adult. Although he cannot beat her, it is still very difficult for an adult male to tie up an adult woman if she resists violently. Not to mention that the woman has to protect her own children, so the energy released must be enormous.

At the very least, there must be defensive scars.

However, it does not.

This shows that Ji Jingfu's wife most likely did not resist at all. The reason is easy to guess: with two children, a mother is easily threatened.

Chen Yi thought about the possibility of an acquaintance, but ultimately found it difficult to judge, because there were many ways to get into the house. It was not necessary to knock on the door. He could climb over the wall and look for an opportunity to launch a sudden attack. He could use the child as a threat to make Ji Jingfu's wife give up resistance. The probability of success was still very high.

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

Tang Hongyi left the meeting room as the Economic Investigation Department needed him to take charge and find the connection between the two cases.

The timing of the murderer's crime was a bit too coincidental. It was only one day after the economic investigation arrested someone, so one has to doubt whether there is a causal relationship.

After Tang Hongyi left, several cigarettes were lit and smoke quickly 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 their things and prepared to run away."

Lu Zhengkai: "Captain Chen said that the invoice case had nothing to do with the murder of Ji Jingfu's family, but because Tang Zhi's investigation led to Ji Jingfu's plan to flee, the suspect took action?"

Chen Yi hummed: "It is possible. It is obvious that the murderer had planned it in advance. As for how long he had planned it, 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 has no idea. The property in his home is intact, which also proves that the murderer is not after money. "

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

No matter what, the task force is facing a very dangerous person this time. He will not even let children go and will be even more ruthless to the police. He is not much weaker than drug dealers and may even fight to the death to resist arrest.

If the identity of a suspect is identified in the future, he must be suppressed with absolute force, not giving the other party the slightest chance to resist.

After listening for a while, Zhou Yebin felt that he could not be of much help and 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 a few others did not leave. They had not received any notice to join the task force and were outsiders. They only needed to follow Chen Yi and do whatever Chen Yi told them to do.

The clock ticked slowly in the early morning. Chen Yi and Lu Zhengkai continued to analyze the case and explored more possibilities. They now needed new clues to support their case, or it would be good to eliminate one possibility.

At four o'clock in the morning, Ji Jingfu's driving trajectory was sent. His car was not a duplicate or fake license plate, and it was easy to check with a little effort.

At present, the Haiyan second-generation analysis system has not yet been popularized nationwide and is currently only operating in first-tier cities and some second-tier cities. In the future, once all cities have implemented the Haiyan second-generation system, it will not only play a great role in capturing traffic violations, but will also bring widespread convenience to the police in combating illegal and criminal activities.

What is the Haiyan system? It can recognize thousands of photos per minute and process up to one million photos per day. It can not only perform intelligent recognition and capture, but also conduct secondary analysis of the captured photos and provide detailed information, including the brand, model, color, annual inspection, items in the car, whether the passengers are wearing seat belts, whether there are any violations, etc.

Its powerful functions lie in its high-precision recognition capabilities and wide range of application scenarios. Not only that, it can also self-learn to identify new and historical models, greatly enhancing the ability to track down violations of traffic rules and laws.

This is undoubtedly good news for criminal investigations, as suspects will have nowhere to hide under the Haiyan system.

"No wonder." After getting Ji Jingfu's daily activities, Lu Zhengkai understood, "He stayed near the branch and municipal bureaus all day to follow the movements of the economic investigation, and even followed the economic investigation car. He must have guessed that he was about to be exposed, so he prepared to run away in advance. Unfortunately, before he could leave Yangcheng from Xintou Town, he was killed by someone unknown."

Chen Yi looked at the information about Ji Jingfu's activities and his departure and return time in his hand and nodded: "He usually comes back at night, but he came back early that day. He came back early because he was about to leave and happened to run into the murderer who had just killed his wife and children.

According to the autopsy report, there was a certain interval between Ji Jingfu's death and his death. He did not die immediately, which means that the murderer was still a little panicked. He stabbed him several times and ran away quickly without confirming whether Ji Jingfu had stopped breathing on the spot.

Lu Zhengkai: "This possibility is very high. The murderer did not expect Ji Jingfu to return home several hours earlier. It seems that he was not targeting Ji Jingfu.

But just in case, we can't stop with Tang Zhi for now, and we have to dig deeper into the case of buying and selling invoices."

Chen Yi nodded in agreement. They should not conclude that Ji Jingfu's motive was the murderer just because he changed his activity pattern on the day of the crime. They should be cautious in this matter. If they go in the wrong direction, it would lead to serious deviations in the entire investigation process.

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

Anyway, there are enough police forces, so there will be no problem in achieving full coverage.

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

"Captain Chen, you take a nap first, I'll keep an eye on it." Lu Zhengkai said. As the leader of the task force, his responsibilities and pressures are much greater than Chen Yi's.

Chen Yi was not hypocritical, and Lu Zhengkai also needed time alone: ​​"Then I'll come over in the morning. Call me anytime if you have anything."

There were still two autopsy reports that had not come out, so the special case team waited until after six in the morning, and then left the Municipal 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 picked out the key points.

There are differences between the two young victims and Ji Jingfu's wife. The biggest difference is that they were abused before their death. There are faint strangulation marks on their necks, which shows that the murderer did not intend to strangle the victims to death, but simply abused them.

The fatal injury still came from a cut throat.

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

Time of death: twenty-eight hours.

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

A novice who could commit such inhumane killings must not be a normal person. Chen Yi had a hunch that if this guy was not caught as soon as possible, something bad might happen.
