Liu Sanxun dialed Lao Lu's phone and reported to him the newly discovered murder scene.

I frowned and crouched down to examine the deceased.

The deceased was lying face down against the open bedroom door and had been dead for more than twenty-four hours. He was wearing light blue close-fitting cotton pajamas and pajamas, and he was wearing a brown cotton slipper on his left foot, while the cotton slippers on his right foot were buckled about 20 centimeters from the deceased's right foot.

The fatal wounds of the deceased originated from five puncture wounds on the back, which were side-by-side and equidistant, and the most lethal were the two puncture wounds that deviated to the left, apparently from the back and punctured the heart, causing the deceased to be instantly fatal.

On the ground, the body of the deceased was spilling a large amount of blood, and it was difficult for me to tell what weapon had caused the injury to him without thoroughly cleaning the wound. But one thing we know for sure, the deceased must have been pierced through the body by this murder weapon, otherwise the amount of blood spilled from the body would not have been so large, almost forming a small puddle.

I carefully turned the deceased's body, and sure enough, there were five wounds on his chest, and this large amount of blood was spilling from the wounds on his chest.

I also found a scratch on the deceased's right forehead, which was also a new one. I got up and checked the bedroom door to determine how the scratch on my forehead had formed.

There was a trace of blood on the doorknob on the outside of the bedroom, which was supposed to have been left by the deceased's forehead hitting the doorknob when he fell to the ground, and it also left a wound on the deceased's forehead.

This scar makes a lot of sense. Normally, after being fatally wounded, the victim falls to the ground in a limp form. And this scar tells me that the deceased did not collapse to the ground, but fell forward with inertia.

I analysed this situation and came to the conclusion that while the deceased was running forward, there was a force of impact from behind him and knocked him to the ground.

This impact must have come from the murderer, and this impact was obviously transmitted through the murder weapon that struck the killer. It is certain that the injuries of the deceased were caused by the murder weapon being thrown through the body from behind. I have to sigh, this killer's arm strength is so good.

I examined the crime scene again, mainly the broken glass in the living room. The glass was left after a window was broken, and it seems that the murderer committed the crime in Room 701, which entered through the window after breaking the glass. So how did the killer get to the window of room 701?

I walked out of room 701 and continued upstairs to find that the roof of the building was unlocked. The rooftop is also very empty, and there is no roof garden or flowers and vegetables.

I checked the closest location to the living room window of Room 701 and found no traces of the rope, and it seems that the killer did not enter the crime scene with the help of climbing ropes or something.

Although I didn't find any strangulation marks on the ropes, I did find a few white marks on the outer wall of the roof parapet, which I believe were marks left by the front half of the soles of the feet rubbing against the wall.

Checking the top of the imprint revealed faint scratches on the exterior wall of the rooftop. I frowned, thinking to myself that the murderer couldn't have climbed from the rooftop to room 701 with his bare hands.

It's a small possibility, but it's not impossible, and I guess the killer had a lot of arm strength, so it's even more likely.

Lao Lu took the investigation team and forensic doctor to the scene of the murder and made a more detailed investigation of the murder scene.

The body of the deceased was transported to the forensic center, and of course I was with me.

During the autopsy, Liu Lili found that a total of 10 wounds on the front and back of the body had lacerations. Specifically, it is to penetrate first and then tear. In this case, I made an analysis and showed that the murder weapon had barbs on it like a fishhook.

Based on the wounds, I determined that the murder weapon was a harpoon.

As night fell, the cold seemed to be even more intense, spreading quietly from the river to the whole city.

However, the cold air could not penetrate the red bar, where the lights were scorching and the music was frenzied.

Of course, when he usually comes to the bar to drink, it is mostly Tang Zhenguo's proposal, the reason is very simple, he wants to drink, he wants to see Chi Xue.

The two fixed positions on the bar seem to have been prepared for me and Tang Zhenguo a long time ago. Tang Zhenguo held the wine bottle and poured the frothy beer into his stomach, while looking at the extremely enchanting Chi Xue with misty eyes.

Chi Xue was wearing a sexy white suit, writhing her body, and the shaker flipped between her palms, winning bursts of cheers.

It was past twelve o'clock in the morning, and perhaps because of the colder weather, the drinkers had left early.

I turned my head sideways to look at a table of drunken youths, a young long-haired girl who was already drunk and unconscious, her head hanging over the shoulders of a handsome young man, as if she had long since lost consciousness.

The handsome young man held a small wine glass, and the glass was half filled with a blue cocktail. He raised his glass and toasted to the two yellow-haired youths in front of him, and then glanced at the girl on his shoulder with an evil eye, revealing an evil smile. The last sip drained the blue glass of wine. At the same time, I seemed to hear the laughter of the youths, a disgusting laugh.

In this world, there are many things that can't go as expected, and there are many things that you can't get used to. I'm not the kind of person who can't get used to it and have to take care of it, the behavior that human beings have produced under their ugly nature is endless, and I can't control it, and I can't control it.

However, some people are just nosy, and when they encounter something that he doesn't like to see, they will beat people.

This kind of person is generally burly, and only with strong physical fitness can he give people a sense of intimidation at the first time, and only then can he have the capital to meddle in things.

Moreover, this kind of person will emit a kind of qi himself, which invisibly forms an aura and makes it impossible for others to get close. It is also because of this qi that he is incompatible with the world, so there will be more unaccustomed in his eyes.

Such a person, I noticed it when I entered the red bar. He wore a black winter hat and wrapped himself tightly in a brown coat. Still, I could tell how big he was.

He sat against the wall of the bar, a table of four people, but no one came to meet him, and he had been pouring himself a drink, not in a hurry, not in a hurry, not in arrogance.

He drank like this all the time, and people came and went around him, but it seemed that there was a magnetic field around him, and no one could enter his range.

Maybe it's more of a reluctance to get close to him.

Only then did he stand up, and he was very tall, a hundred and ninety centimeters. He didn't leave the bar, but walked over to the three riffraff.

He looked at the three ruffians and said nothing.

The three ruffians were drinking and laughing, when they suddenly saw such a behemoth standing beside them, and the laughter suddenly stopped.

"Big guys? Want to find faults? The handsome man stood up and said with his mouth crooked.

I nudged Tang Zhenguo and motioned for him to look in the direction of the big man.

Tang Zhenguo took a sip of wine, put the bottle on the bar, and turned his head to look at the big man.

"This man has practiced." Tang Zhenguo said affirmatively with a professional vision: "Those three boys will suffer." ”

"What, if you drink too much, you're going to make trouble? Don't make trouble on the old lady's turf! Chi Xue had already rushed out of the bar at this time, dancing and shouting loudly.

Tang Zhenguo said with great certainty: "Those people will suffer!" ”

I'm sure of Tang Zhenguo's statement.

"Hurry up and give me the money for the drink, and get out. You, Tuzuaner (nickname), leave this little girl here with me, look at your cheap appearance, and I don't know where to go to a good woman. Roll it, get it. Chi Xue scolded and pointed at these big men and said.

The handsome man wanted to refute a few words, but he lost his temper when Chi Xue stared at him. This Sister Chi's name is also well-known in this area, and it seems that subduing these three little ruffians is still not a problem.

The three little ruffians looked helpless, feeling like they were saying, they didn't know who to provoke, and they were so unhappy to drink. The three of them paid for the drink and left the bar in a gloomy manner.

The big man looked at the girl who was sleeping unconscious on the sofa, and then at Chi Xue, who was crossed over his waist and had an angry face, took out five hundred yuan from his pocket, gently put it on the wine table, and then walked slowly out of the bar.

Chi Xue handed over five hundred yuan to the bartender and asked the bartender to find money for the big man, but the big man didn't seem to plan to let Chi Xue find money, and had already walked out of the bar door at this time.

The bartender hurried out of the bar, trying to give the big man the money he was looking for, but the big man had long since disappeared into the night.

The next morning, I received a call from Lao Lu, saying that there was another murder.

Tang Zhenguo went to Chi Xue's house last night, so I got into Liu Sanxun's car alone.

Liu Sanxun's driving skills are useless in the traffic jammed city, and what he is best at this time is to quickly press the car horn. His actions are no different from Lao Lu's scolding street.

Coming to the scene of the murder, this is an open residential building on the side of the road, the deceased's family lives on the third floor of the street, and the two floors below are storefronts and shopping malls.

The deceased was a woman who was strangled to death in her bedroom bed. His husband happened to be on a business trip to Chengdu these days and was not at home. The body was found by the woman's six-year-old son, and when the child found that his mother could not wake up, he called for help from a neighbor, who called the police.

I examined the body and found that the deceased's injuries were strange because the bruises on her neck were large and were caused by one right hand. I compared, and this hand is much bigger than mine.

From the size of this hand, I can deduce that this man must be more than 190 centimeters tall and extremely powerful.

His modus operandi was also very simple, that is, he came to the bedroom of the deceased, and immediately choked the deceased's neck and suffocated him to death. There are no fancy and no designs.

I observed the crime scene and found that the murderer had come in through the window, because there were still some relatively large pieces of dust left in the aluminum alloy grooves of the sliding window, which was obviously not wind-blown dust, but dust that fell from the soles of the murderer's shoes.

I ran downstairs and checked the distance between the windows and the bottom floor and the perimeter of the windows. So he took off his coat and threw it to Liu Sanxun, and began to climb up. Following a pipe, I climbed to the window outside the mall, and then climbed to the deceased's room from the billboard next to the mall window.

Of course, when I climbed the house facing the street in the blue sky and daytime, there were many people who came to watch, but fortunately, Liu Sanxun kept explaining to me below, otherwise I would have been regarded as a madman or a snitch.

I wondered why the killer was so bold. It's on the street, and even in the middle of the night, there will be a small number of cars passing by, isn't he afraid of being discovered?

Although the perpetrator's method is simple, it reveals several characteristics of the perpetrator, which I find very interesting.

First, choosing to climb into the crime scene with bare hands shows that the perpetrator is agile; second, strangling a large living person with one hand, this kind of power is not something ordinary people can have; Third, audacity.

Through these three characteristics, I analyzed that the perpetrator was not a simple murderer, but was likely to be a professional killer.

Could this be related to the three previous homicides?

Then it is necessary to investigate the background of this victim.

After the police investigated the female victim, I immediately got her information from Lao Luna.

The woman's name is Jiang Qiuliu, 29 years old, a stay-at-home wife, a six-year-old son, and her husband is a car salesman. Jiang Qiuliu had a history of drug abuse when he was young, but he has quit for many years and has not relapsed. She has almost no friends, except for playing mahjong with her neighbors at home with her children, and has never made a feud with anyone.

In the preliminary investigation of Jiang Qiuliu's background, it is difficult to see the cause of her death. But I have an inexplicable feeling that her death was the same person as the previous three homicides.

Because these four murders all seem to have only one purpose, to kill people, and this purpose is largely vendettas.

The previous deaths of Xie Shikun, Kong Baohua and Li Shujian were very likely because of a woman, so will this woman have a connection with the dead Jiang Qiuliu?

So I took Liu Sanxun and Tang Zhenguo to Jiang Qiuliu's hometown, Yankou Village, Longsha Town, Wanzhou District, and found the home where Jiang Qiuliu once lived.

Now this old house is only inhabited by Jiang Qiuliu's grandfather, and he doesn't know that Jiang Qiuliu has passed away at this time.

The old man must be almost eighty, but he is still in good health, and when we came, he was cleaning in the yard.

I could detect that the old man saw Liu Sanxun at first sight, and he showed a sense of nervousness, and even his hand holding the broom trembled a little.

"Comrade policeman, Liu Liu is taking drugs again?" The old man asked Liu Sanxun in a trembling voice.

Liu Sanxun didn't know how to answer, so I hurriedly said: "Old man, no, Xiao Jiang has already quit drugs, you see that she is now the mother of a child, this parent has to set an example, how can she still take drugs?" You can rest assured. ”

The old man nodded incessantly, put the broom by the wall, and invited us into the house.

The room was a two-storey house of blue brick, also unique to the countryside, but there was no furniture in the room, except for a square table, four stools, and three low wooden chairs with backrests in the living room.

I exchanged a few words of greeting with the old man, and then asked, "It's not easy for you to bring Jiang Qiuliu up since you were a child, right?" ”

I asked this because I knew that Jiang Qiuliu's parents divorced when she was very young, and both of them left Jiang Qiuliu, who was only three years old, to go to other places, and they have not been heard from for decades.

Jiang Qiuliu was raised by her grandparents, and her grandmother also died when Jiang Qiuliu was 15 years old, and it was all up to her grandfather to raise her alone. However, fortunately, Jiang Qiuliu is handsome, so in adulthood, even if her family background is not good, there are still many men who are really good to her. It's just that the methods of good men are always inferior to bad men, so Jiang Qiuliu was deceived by men when he was young and became addicted to drugs. But fortunately, she stopped the precipice in time, successfully quit drugs, and met her current husband. It's a pity that the heavens did not fulfill people's wishes, and they suffered a tragic disaster, and they died in vain.

The old man said not very clearly: "I don't have anything hard, but I suffer the child." But now that she's married, she has children, and I'm relieved to be an old bone. ”

Listening to the old man's words, I felt a sour taste in my heart. I don't know what the old man will be sad after learning the news of Jiang Qiuliu's death.

I stood up and said to the old man, "Can you take me to the room where Jiang Qiuliu used to live?" ”

The old man nodded, slowly stood up, and led us to the second floor.

The most sunny house on the second floor is Jiang Qiuliu's childhood room, the room is not locked, and the house is very tidy, even the desktop and bed are spotless, as if someone lives often. I know that this is the reason why the old man often cleans the room, and it seems that the old man is using this way to express his thoughts about his granddaughter.

The furnishings of this room are also very simple, with a small bed, a small desk and a small wardrobe. The only thing that makes the room a little more colorful is the stickers on the walls and the photos of the headshots.

I found in the headsticker on the wall that Jiang Qiuliu had a lot of photos with a quiet-looking girl.

So I asked the old man, "Who is this girl?" ”

The old man even replied without thinking: "You mean Cheng Xiaowei, she is a good friend of Liu Liu." ”

I asked again, "Where is this girl?" ”

The old man shook his head and said, "It's a pity that she hanged herself under a tree in her yard many years ago. ”

I chuckled and asked, "Why did she kill herself?" ”

The old man said: "I don't know about this, there were a lot of rumors back then, most of them were related to negative people." ”

The detective's sense of smell tells me that this Cheng Xiaowei, who hanged himself, could it be related to these four murders?

I have a hypothesis if Cheng Xiaowei can be related to Xie Shikun, Kong Baohua, Li Shujian and Jiang Qiuliu. Then, these four cases can be completely connected.

After leaving the old man's house, I asked Liu Sanxun to investigate this Cheng Xiaowei as soon as possible.

The results soon came out, Cheng Xiaowei is also from Longsha Town, Wanzhou District, but her family lives in the town of Longsha Town, and her parents run a restaurant in the town.

We came to the town of Lonza again and found this restaurant.

It was close to noon, so we simply dined at this restaurant.

The three of us ordered nine mutton grids, two plates of pickles and pork, a large bowl of kelp soup, and three bowls of dried rice. We are still more principled and never drink alcohol during work.

To be honest, the taste is really good, and the portion is more real than the one in the city, which is simply a conscientious businessman.

Satiated...... No, after the meat and food were full, I asked Liu Sanxun, who was in uniform, to take the lead and ask Cheng Xiaowei about it.

Liu Sanxun is a rough man, he walked to the kitchen, took out his police officer card and said: "I am Liu Sanxun of the district criminal investigation team, and I want to know something about Cheng Xiaowei from you." ”

This Liu Sanxun was full of anger when he spoke, and everyone in the small restaurant heard him.

A man who was nearly fifty years old hurriedly walked out of the kitchen, wiped his hands on the oil-stained apron on his chest, and said with a bitter face: "Comrade policeman, my family Xiaowei has been gone for so many years, what are you still looking for her?" ”

At this point, I heard the diners around me start whispering.

"It is said that the eldest daughter of the boss's family committed suicide, do you know what the reason is?"

"I heard that I was pregnant with a wild seed, and the man ran away, and he hanged himself when he couldn't figure it out."

"Nonsense, Xiaowei is such a sensible daughter, it's impossible. I heard that I met a bad guy and was killed by that, and I couldn't figure it out for a while, so I hanged myself. ”

"Hey, do you know, every June, Cheng Xiaowei's grave will be inexplicably renovated, and there will be five-colored ribbons left on the grave, which is very mysterious."

"I've heard it, and I've seen it specifically, every year, it's eerie, and it scares people to death. It is said that the people in her house did not dare to go to the grave when they burned incense and paper, and they all burned it by the Tiankankan in the distance. ”

......

Hearing this, I hurriedly stepped forward and said to Cheng's father, who was talking to Liu Sanxun: "We are just curious, why is Cheng Xiaowei's grave renovated?" We are here this time in the hope of breaking these feudal superstitions. Can you take us to Cheng Xiaowei's grave? ”

Cheng's father glanced at me with a skeptical expression, but he still instructed his little daughter, who was serving food in the store, to take us to Cheng Xiaowei's grave.

Cheng Xiaowei's graveyard is on the edge of a deserted farmland that has long been overgrown with weeds. The youngest daughter of the Cheng family pointed to the cemetery in front of the farmland and said, "That's my sister's grave, you should be careful." ”

From the words of the youngest daughter of the Cheng family and her hesitation, it shows that she is very afraid of the grave of her biological sister, perhaps this is related to the legend that there are ghosts and ghosts in the cemetery.

I never believe in ghosts, of course, the rough man Liu Sanxun and the tough guy Tang Zhenguo, the two men with strong yang energy, it is estimated that only the ghosts are afraid of them.

I walked to the grave and folded my hands three times as a sign of respect for the deceased.

When I finished my prayers, I felt a cold wind blow through the trees behind the grave.

This grave is very simple, just a few irregular stones piled up, and there is not even a tombstone.

There are a lot of ribbons on the grave, some of which are still very new, and the rest are weathered. I checked it, and there were only five colors of the streamers, blue, red, white, green, and yellow. There must be some symbolism in these five colors of ribbons, but I can't figure it out for a while.

In fact, the most striking thing on the grave is a bouquet of flowers, this bouquet of flowers is pure white roses, and it is a bouquet of white roses that have just been placed here.

Who put this bouquet of white roses here?
