Liu Lili found in Xie Shikun's autopsy that the poison on the flying needle affected the muscle groups on Shikun's body, making his entire muscle group in an extremely relaxed state. This state of muscle relaxation causes the intercostal muscles, diaphragm, abdominal wall muscles, sternocleidomastoid muscles, back muscles, thoracic muscles and other muscles related to breathing to lose their motor effect, thus causing Xie Shikun to suffocate to death.

At the same time, on the eve of his death, he did not save himself or struggle, also because his entire muscle group was in a state of complete relaxation and paralysis.

This kind of poison that killed Xie Shikun made me feel incredible. When the flying needle was shot into Xie Shikun's neck, the poison entered the brain through the neck artery, and the brain instantly entered a state of paralysis, and then the poison invaded the whole body through the flow of blood, making the entire human body function immediately in a state of stagnation. The first thing to stagnate is breathing, and the loss of respiratory function makes the poisoned person suffocate in an instant.

I think this poison should belong to the bloody throat seal in martial arts novels, and there is only one death after poisoning, and there is no cure at all.

The technical department analyzed the flying needle and found that the poison on the flying needle was an unknown poison, specifically a variety of poisons in a certain proportion. The main ingredient of the poison comes from the 'poison dart frog'.

The poison dart frog in the jungles of South America has a gorgeous appearance, and although it is only 2 to 4 centimeters long, it can be called a natural "chemical weapon". Its skin glands are abnormally well developed and secrete brightly colored venom that is used for self-defense. Don't underestimate this venom – just 100,000th of an ounce (1 ounce = 28.3495 grams) can kill someone! Although dart frogs themselves do not use venom to hunt their prey, the Indians of South America learned to collect their venom and apply it to arrowheads for hunting animals, hence the name poison dart frogs.

The white feathers on the flying needle were analyzed and found to be the feathers of the white falcon.

In Chinese history, during the Liao, Jin and Qing dynasties, it was used for hunting by the ancient emperors in the north, and was regarded as a rare bird, called "Haidongqing", when the falcon was already a priceless bird of prey. As early as the Tang Dynasty, Haidongqing was already a valuable tribute to the Central Plains Dynasty of the Manchu ancestors. In the Jin and Yuan dynasties, there was even such a rule: all criminals who violated the criminal law and were banished to Liaodong, whoever could catch the falcon and present it could atone for their sins and be released. In the Qing Dynasty, a falcon was worth 30 taels of silver (equivalent to the income of half a lifetime of the mean), which shows how precious it is.

In fact, the flying needle of this * tube does not need to use animal feathers as a tail at all, it only needs a membrane tail of a cone to be stable enough. It seems that the killer used the feathers of the white falcon as the tail of the flying needle, just to show his dignity.

Finally, I studied what material the needle body of the flying needle was, and it turned out to be a precious German Krupp steel.

After I got this information, I was more sure that the murderer was a professional killer, but why would a professional killer attack a grocery store owner?

The first thing that came to my mind was to buy homicide. However, I soon overturned this idea, and found out in my network with the investigator Xie Shikun that the people who came into contact with him were ordinary civilians. Even if we were negligent in our investigation, we did not find out that the deceased had a previous vendetta, which led to the murder. But could this murderer who bought it be such a professional professional killer?

I reckon it would be difficult for the average person to relate to such a professional killer. The first is that there is no contact channel, and this well-equipped professional killer is not meat placed in the vegetable market, which can be accessed by anyone; The second is the issue of commissions for professional killers, can ordinary people afford expensive remuneration for killing?

Obviously, the likelihood of buying a homicide is slim to none.

Money killing? This is also impossible, the police investigation knows Shikun's property, he doesn't even have a real estate, can a professional killer kill him for his family property?

Love killing? This is even more impossible, visiting Shikun's relatives and friends, they all know that he lives alone, how can he say that he is in love.

Manslaughter? Such a well-prepared assassination plan could never have been a manslaughter.

Then in the end, only vendetta remains. And Xie Shikun's enmity is not with others, but with the killer himself.

Although this article seems to be very outrageous, it is more likely than the previous motives for killing.

Maybe I've been emphasizing that the killer is a professional killer and that people are misleading. A professional killer is also a human being, and we see him as an ordinary person, an ordinary person who kills for revenge.

In this way, is it easier to understand that an ordinary person used an unusual method to kill another ordinary person?

Of course, my set of arguments and inferences are just my personal thoughts, or even a kind of conjecture, and the police will obviously not adopt them.

On the third day of Xie Shikun's murder, the police received another report that a drowned male corpse had been found in the Ganning Reservoir.

Previously, the police did not link the male body to murder, but only determined that he had fallen into the water. However, because of my curiosity, I went to the forensic center to request an autopsy of the deceased, and I found something strange.

The deceased had ecchymosis on the back of his neck, which was left by a strong pinching of the back of his neck.

The cause of death of the deceased was determined to be drowning, and the time of death was between 10 and 11 p.m. But this drowning of the deceased cannot be regarded as an accident, but by being forcibly pressed into the water and suffocated to death.

This is illustrated by the bruises on the back of his neck, which are clearly evidence of the killer's hard strangulation of the back of the deceased's neck and pressing him into the water.

I found Lao Lu and got the information of the deceased.

The deceased's name is Kong Baoguo, male, 39 years old this year, no fixed occupation, unmarried, hobby fishing, and was once detained by the public security organs for soliciting prostitution.

Kong Baoguo also fished at night before his death, but his fishing method was different, he drove a small wooden boat to the center of the Ganning Reservoir to fish.

After learning about the situation of the deceased Kong Baoguo, I found that he and Xie Shikun had something in common.

The first is that they all love fishing, and they love night fishing, so they should all belong to fishing enthusiasts; The second is that both of them are single and living alone; The third is that they all have a bad habit of soliciting prostitution.

Based on these three commonalities, I suspect that Kong Baoguo and Xie Shikun were killed by the same person. On the day Kong Baoguo was killed, he drove a boat to the middle of the Ganning Reservoir to fish, so I estimate that the murderer's method of killing was to use his superior water ability to get close to the boat that Kong Baoguo was on, and then attacked Kong Baoguo on the boat with his bare hands and drowned.

I reported the situation to Lao Lu, who attached great importance to it and re-judged Kong Baoguo's death from an accident to a murder case. Police officers were also dispatched to the Ganning Reservoir to investigate.

During the investigation around the Ganning Reservoir, I found another flipper print, and judging from the shape of the flipper prints, these flipper prints are exactly the same as those found in the Lujiaba Reservoir. Then it is further certain that the murderer of Kong Baohua is most likely the murderer of Xie Shikun.

Apart from finding flipper prints, no more valuable clues were found.

Both bloody cases took place in the reservoir, and the deceased were all anglers, so what was the purpose of the murderer? I can't figure it out.

The murderer's modus operandi was clean and clean, and there was very little evidence left at the scene, and it was quite difficult to solve the case in a short period of time.

Since it is difficult to find the murderer directly, I will change my thinking and start with the two victims.

In order to break the haze in the case and find more and closer ties between the two victims, I worked with Tang Zhenguo and Liu Sanxun to find the family of the second victim, Kong Baohua.

In Hekou Village, Ganning Township, we came to Kong Baohua's home. Because Kong Baohua has never been married, and he only works as a temporary worker in Wanzhou all the year round, he has not separated from his parents.

Kong Baohua's parents are authentic farmers, and now they are both over sixty years old, and they have already cried dry tears when they have the bitter work of sending black-haired people to white-haired people.

At this time, because the public security organs were still investigating the murder of Kong Baohua, Kong Baohua's body had not been returned to the Kong family for the time being, and the Kong family had certainly not officially handled the funeral.

However, the Kong family was full of guests with heavy moods at this time, and they should have come to comfort the second elder.

The Kong family seems to be a relatively well-to-do family in the countryside, with a two-story house in the fenced courtyard, the exterior of which is covered with dark red tiles, and each window is inlaid with silver aluminum security nets.

When I entered the yard, I found that the ground of the yard was paved with stones, which was higher than the flat earth yard or the yard with concrete floor.

A black dog tethered to the eaves saw a stranger enter his yard, and it was a vicious barking dog that jumped up and down.

The people standing in the courtyard saw our arrival and hurriedly shouted to the back room: "The police are coming, the police are coming." "It's all because the people in the courtyard saw Liu Sanxun's uniform.

An old man with white hair rushed out of the room, his eyes red and his face wrinkled. Behind him was an old woman, helped out of the house by two middle-aged women.

"Comrade policeman, you have to make the decision for my family Baohua." The old man said to Liu Sanxun with a sad face.

Liu Sanxun said: "Don't worry, we will definitely catch the murderer." ”

The old woman didn't seem to be standing very steadily under the support of the two, she cried towards Liu Sanxun, and said: "My family Baohua died so miserably, you must catch the sinner of that day and avenge my family Baohua." ”

As soon as the old woman cried like this, the scene was a little chaotic, and the guests blamed the murderer one by one, and they were all emotional and angry. If the murderers were really here, they would have to be eaten alive.

I simply went to the courtyard and learned about Kong Baohua from everyone. Of course, these people are all family members of Kong Baohua, and they all say how good Kong Baohua is, how kind he is to others, how diligent he is, and so on. But I'm not swayed by these remarks, and I don't want to comment too much on the inner qualities of a person who has been detained for soliciting prostitution.

During the inquiry, I found that among these relatives, a country woman of about thirty years old was silent, but her expression was not indifferent, but when everyone made comments about Kong Baohua, she listened attentively, and always showed a contemptuous smile when she heard the exaggerated praise of Kong Baohua.

I know that from this woman, I can discover the true side of Kong Baohua.

In Kong Baohua's home, I didn't get anything of value at all, so I left my last hope for the taciturn woman.

After leaving Kong's house, we didn't go far, but parked the police car on the road to Kong's house, I had to wait for that woman and learn from her about Kong Baohua's true side.

I hope I'm not wrong about this woman's guess.

At half past four in the afternoon, the woman walked out of Kong's house. I was very puzzled, I had expected this woman to leave after dinner, but I didn't expect to leave early alone.

Liu Sanxun looked at me, and I nodded to him.

Liu Sanxun hurriedly got out of the car and walked quickly to the woman's side, the woman's expression suddenly looked very nervous, and her hands were kept kneading in front of her lower abdomen. In the end, she nodded and got into the police car with Liu Sanxun.

After the woman got into the police car, she became even more nervous, and kept her head down, as if she had made something wrong.

I sat in the passenger seat and turned my head to the woman and asked, "What's your name?" ”

The woman's voice was like a mosquito fly: "My name is Zhang Pinglian." ”

"What is your relationship with Kong Baohua?"

Zhang Pinglian kept hanging her head and said, "He is my cousin." ”

I nodded slightly and said, "Do you have any holiday with Kong Baohua?" You don't have to be afraid, I don't doubt you, I know that Kong Baohua's murderer is a man, I just want to know more about Kong Baohua's personality and judge why he was brutally killed? ”

Zhang Pinglian was silent for a long time, slowly began to sob, choked up and said: "God opened his eyes, God really opened his eyes, Kong Baohua, this bastard was finally accepted by God." ”

I frowned and asked, "What do you mean by that?" ”

Zhang Pinglian slowly raised her head, brushed her forehead bangs, wiped her tears and snot, and said: "Kong Baohua is a scumbag, he tricked me into his house when I was nineteen years old, and took a picture of my body with his mobile phone, threatening me to publish the photo if I said it." And used photos to blackmail me into having sex with him many times, and finally got me pregnant. So he arranged for me to go to a small clinic in the city to have an abortion and live in a run-down hotel. Due to the irregular operation of the abortion in the small clinic, coupled with my low mood and poor nutrition during the recuperation, I was unable to have children from then on. After that, in order to avoid Kong Baohua, I went to work in other places. After I came back at the beginning of this year, Kong Baohua threatened me with what happened before. But I didn't refuse him, as long as he was willing to give me money every time, I promised him. So Kong Baohua gave me a symbolic 100 yuan each time, and we maintained this unclear relationship until he died. ”

I'm not interested in their relationship, I'm more interested in whether Kong Baohua revealed anything to Zhang Pinglian during his contact with her, and whether these things can be related to Kong Baohua's death?

I asked, "In your contact with Kong Baohua, did he say that he had a grudge against people?" Or have you offended someone? ”

Zhang Pinglian thought for a while and said, "Not really. Because Kong Baohua's life circle is very small, he doesn't play mahjong, and the money is used to prostitute women. The friends were just a few fishing friends, and those people seemed to have met on the construction site when he was younger. ”

I asked, "Do you know his fishing friends?" ”

Zhang Pinglian said: "We have met several times, but I can't name them. ”

I hurriedly said to Liu Sanxun: "Do you have a photo of Xie Shikun?" ”

Liu Sanxun took out his mobile phone and flipped through it, handed it to Zhang Pinglian and said, "Do you know this person?" ”

Zhang Pinglian took the phone, only to see her eyes roll left and right, and after a pause of about two seconds, she said, "I don't know." She said this with some seriousness, obviously lying.

She handed her mobile phone to Liu Sanxun, and then said, "I'm going home to cook dinner for my father, can I go?" ”

I nodded.

Zhang Pinglian got out of the car in a hurry and strode forward, without even looking back, obviously having something in her heart.

After Tang Zhenguo got out of the car with Zhang Pinglian, he said: "This woman is ghostly." Don't look at her dressed as a country woman, she also wears perfume, and her eyebrows are painted, although the clothes are not very good, but you see her walking and talking, not like an authentic rural woman. ”

I smiled and said, "Zhenguo, you have a good way of observing women!" ”

Tang Zhenguo said: "I have one thing to say, am I wrong?" You see that this woman was so badly harmed by Kong Baohua, I think she is also suspicious. ”

"If Kong Baohua's case had been related to her, she wouldn't have told us about her experience," I said. And ordinary women would not say this kind of thing in the open, but this Zhang Pinglian is very strange, she said. Of course, I know that she has a complaining mentality in it, and more importantly, I think she has become numb to the privacy of men and women. Xiao Liu, go back and check this Zhang Pinglian, maybe she is the breakthrough in the case. And I'm sure she knows Xie Shikun. ”

Liu Sanxun still played his thunderous style, and soon found out Zhang Pinglian's details.

It turned out that a year ago, Zhang Pinglian was detained in Guangzhou for selling yin. And the investigation shows that Zhang Pinglian went out to work that year, and she participated in the yin selling organization and was a senior 'young lady'.

Based on this, I surmised that Zhang Pinglian must still be engaged in this business after returning to her hometown, and Kong Baohua, the person who once harmed her all her life, has become her frequent visitor. Maybe Kong Baohua's fishing friends are also her guests.

The criminal investigation team summoned Zhang Pinglian, and Zhang Pinglian explained her relationship with Kong Baohua and Xie Shikun in front of the police providing her previous files.

Because of the state's heavy blow, engaging in illegal yin selling activities has been severely cracked down. Zhang Pinglian, who was unemployed, returned to her hometown and wanted to find a serious job, but she was threatened by Kong Baohua again.

However, at this time, Zhang Pinglian was no longer the ignorant country girl of the year, but an experienced Fengyue master.

So he pushed the boat down the river, used his body, and obtained some living expenses from Kong Baohua.

Because of Kong Baohua's relationship, she met some fishing friends around Kong Baohua, including Xie Shikun. After Zhang Pinglian learned that Xie Shikun also had bad habits, she took the initiative to talk to him, and successfully attracted Xie Shikun and developed Xie Shikun into a regular visitor. Xie Shikun felt that Zhang Pinglian was the safest here, and even if they were discovered, they could confess that it was a couple, so he was happy to accept it.

In Zhang Pinglian's confession, she said something that shocked me.

It turned out that after Xie Shikun was drunk once, he found Zhang Pinglian and gave Zhang Pinglian a benefit fee of 800 yuan. Zhang Pinglian joked with him at the time that she was not the most expensive woman Xie Shikun had ever played. Xie Shikun laughed, he said that the most expensive woman he had ever played with was spent 3,000 yuan, and she was a virgin. Also going to play with him were Kong Baohua and another fishing friend, Li Shujian, but the two only paid 1,000 yuan.

Zhang Pinglian only knows so much, as for who is the woman who was toyed with by the three of them? There's no way to know now.

I wondered in my heart, could that poor woman be the root cause of the killing of Xie Shikun and Kong Baohua? If this is really the reason, then will the third person, Li Shujian, be in danger?

I asked Zhang Pinglian about Li Shujian's contact information, and Zhang Pinglian really also has Li Shujian's phone number and address, it seems that the relationship between Zhang Pinglian and Li Shujian is not simple.

I dialed Li Shujian's phone, but it was already turned off. I thought in my heart, could it be that this Li Shujian has also been killed?

Some things become prophecies, and some things will become prophecies.

Tang Zhenguo and Liu Sanxun and I found Li Shujian's home, his family lived in the town of Gaofeng Town, Wanzhou District, but after arriving at his house, we only met Li Shujian's wife at home. Her wife said that Li Shujian's phone had not been able to get through since yesterday morning, and if she couldn't get through this afternoon, she would be ready to go to a rental house in the city to find him.

I felt that the matter was urgent, and asked Li Shujian's wife to accompany us to find Li Shujian. But his wife said she would not leave until 4 p.m., when she picked up her son from kindergarten. So we asked her about the location of Li Shujian's rental house in the city, and rushed to the destination.

Li Shujian's rental house in Wanzhou is located in a residential building in Zhoujiaba, which was built in the late nineties and is only seven stories high. And Li Shujian's rented house is on the seventh floor of this building.

Coming to the seventh floor, 701 is Li Shujian's rented house. The security door of this room is still the same old iron fence style, with a yellow paint on the inside, and the wooden door with 701 printed on the door panel is locked.

I tapped the door a few times, but no one answered. Lao Lu is not here, and I have a lot of room to play my lockpicking skills.

Opening such ancient doors is effortless.

As soon as I entered the room, I saw a broken window in the living room and broken glass on the floor. And by a door that connects the living room to the bedroom, a man collapsed in a pool of blood.
