Jiang Feng expressed his opinion.

There was silence in the entire conference room.

Everyone was thinking about digesting Jiang Feng's words.

Judging from Jiang Feng's words, there is no doubt.

It is likely that the killer has developed an antisocial personality and developed a set of extreme understandings of his own.

At this point, there must be an extremely close connection with the murderer's motive for committing the crime.

But the key is...... What is the connection with the murderer?

How did the murderer come up with such radical thinking?

As a veteran criminal investigator, the captain of the first team is still extremely experienced.

He looked at the file, thought about it, and said: "The deceased were all killed by a blow to the heart, and the murder weapon was identified by the forensic doctor, the heart was next to the front chest wall, in addition to the skin and ribs of the chest, there was a layer of visceral pleura underneath, which was the heart. Therefore, the heart is only about three centimeters away from the surface of the skin, and as long as it is more than five centimeters of sharp weapons, it can hurt the heart.

According to the forensic identification of the deceased's body, although the fat and thinness of each deceased were different, the murderer used the same murder weapon every time, a cone-shaped sharp and long object, and successfully pierced the heart. According to forensic speculation, the length of the murder weapon should not be less than 9cm. ”

"I think it's probably a dagger."

Every time the murderer commits a crime, it is a couple, and in addition to the deceased, the other person always stabs several times in the abdomen, but none of them have anything to do with fatal injuries and can be successfully treated.

According to what has been found so far, the number of bayonets received by the survivors is different each time, is there any correlation between this? Maybe it has something to do with the idea that the deceased is pursuing? ”

After the captain of the first team analyzed, he gestured and said: "Judging from the known information, the murderer is holding a dagger not less than 9 centimeters as a murder weapon, and he has enough understanding of the human body, so he can avoid the key point on the survivor's body, which may be able to give us some enlightenment in the identity of the murderer, and the murderer must have relevant medical experience." At the same time, it is not excluded that the murderer has deliberately studied the vital aspects of the human body, or has undergone professional training, such as being a soldier, retired from the armed police, etc......"

"But the most important suspicion is that they have relevant medical experience, because the survivors are all stabbed in a drug coma, and they can obtain a large number of relevant drugs, which is difficult for people in other professions to do."

Jiang Feng and the group of police officers quietly listened to the analysis of the captain of the team.

Director Zheng Daodao watched everyone gradually enter the state, and he was extremely satisfied.

Soon, the basic context of the entire case was sorted out.

All the police officers present at the scene had some knowledge of the case.

Then, a very important question arises.

The murderer left no traces, and the survivors of the year knew nothing about the murderer's situation, and all of them were in a coma and were stabbed.

This brings up a key issue.

Every crime committed by the murderer was obviously chosen, and in the past five years, what did the five murdered families have in common that led to them being chosen by the murderer?

Soon.

The captain of the first team made arrangements.

Interview.

The institute took action to visit and investigate the surviving families of the victims to understand the joint problems.

Jiang Feng also received the task of visiting.

Let him visit the victim of the first case.

In the first case, which occurred five years ago, the deceased was a woman in the couple, a beautiful woman named Xu Ruoxin, and the survivor was named Tao Yongguang, a leukemia patient.

Tao Yongguang, male, 43 years old, leukemia patient, used to be an employee of the sales department of a small and medium-sized sales company, worked diligently and often went to various liquor stores, but later due to the detection of leukemia, and many chronic diseases, can no longer work.

He resigned.

Jiang Feng took Tao Yongguang's information, and he took a taxi to Tao Yongguang's current residence in Lutan City.

An urban village.

When Jiang Feng arrived, he knocked on the door.

The door was opened by a middle-aged man with a bloodless face.

After Jiang Feng briefly introduced his identity, Tao Yongguang invited him into the room and sat down.

The interior of the room is very simple, with a folding table, a red plastic stool, and a bed...... Not even a wardrobe.

In addition, it has a very strong Chinese herbal flavor.

"Are you drinking Chinese medicine?" Jiang Feng asked.

Tao Yongguang coughed, he nodded and said: "Well, Western medicine costs too much money to treat diseases, and a bottle of special medicine is fifteen or six thousand yuan. ”

When Tao Yongguang said this, he smiled and said: "I saw a shared recipe on the Internet a while ago, so I thought I would try it, maybe Chinese medicine will produce miracles." ”

Jiang Feng's lips pursed slightly, a little silent.

Seeing this, Tao Yongguang didn't feel anything.

He said, "You are here for my wife Xu Ruoxin's affairs, right?" That case, hasn't it been solved yet? ”

Jiang Feng nodded, and he said, "I came this time to learn from you about the situation back then. ”

Tao Yongguang was very cooperative: "You ask, but I don't think I can give you any useful answers." ”

"At the time of the crime, I was in a coma, I don't know what the situation was, and when I woke up, I found that my abdomen was bleeding constantly, and then I was saved......"

When Jiang Feng heard this, he nodded, and did not dwell on this point, but chatted with Tao Yongguang about some of the situation of their family back then.

Soon, Jiang Feng got a lot of information from Tao Yongguang.

He secretly made a summary.

Poor couples mourn everything.

Tao Yongguang at that time, was young and promising, in their hometown of ten miles and eight townships, they were all famous handsome young people, and they relied on their own hard work in the sales company at a young age, and bought a house in a big city like Lutan City, with an income of 70,000 yuan a month.

And after he was introduced, he married his wife Xu Ruoxin, who was introduced by the village, and Tao Yongguang, who became a family, worked harder in his career, because he wanted to give his wife better living conditions.

In this way, he doesn't like to drink, and he forces himself to pour a large amount of liquor into his stomach on the wine table day by day, just to make the bosses who can afford the goods smile.

For this reason, he even once was teased at a party full of bosses, and it was not enough for the teased to learn the pig cry first, and he was forced to lie on the ground and imitate the pig call.

As a result, he was diagnosed with leukemia during a physical examination.

There is no rule of law for this disease, it is all supported by foreign special drugs, a bottle costs fifteen or six thousand yuan, and the money he earned was soon eaten like running water, and the quality of life of the family declined rapidly.

Tao Yongguang wanted to commit suicide more than once, but he was persuaded by his wife Xu Ruoxin.

And Xu Ruoxin, a full-time wife who has always been pampered, has taken on the burden of the family, from a wife who used to often go to luxury shoe stores to a salesman who sells shoes.

Tao Yongguang once secretly went to see it, and his wife squatted on the ground humbly trying on shoes for the ladies, just like the salesmen who once tried shoes for her, which made Tao Yongguang feel distressed.

And slowly, the family conflicts also broke out because of the long-term illness and incurable illness, and the wife's frequent questioning made Tao Yongguang's heart ache.

Why do you want to reduce the quality of life of your wife because of yourself? Tao Yongguang's heart always echoed his wife's questioning.

But after a while, there were fewer quarrels between husband and wife, and he found that his wife Xu Ruoxin seemed to have changed as a person and changed back to before.

There were no more conflicts in the family.

This scene made Tao Yongguang feel even more wasted, just when he was about to beg for death again, but he didn't commit suicide, and the case happened.

His wife died, but he lived.

"Why is the murderer? Why didn't you kill me, but my wife? Tao Yongguang buried his head in grief.

When Jiang Feng heard this, his eyes were thoughtful.

There seems to be a string in my mind, looming in the background.

Tao Yongguang's demeanor and expression are problematic.

He, there is something to hide.
