Rainy night.

The miserable light rain is like an abandoned bride, it is very sad, this sadness is very strong but dare not speak loudly, it can only stay alone in the empty room, in the dark to the window period Ai Ai's tears, the voice of resentment is intermittent, venting its heartbroken grief.

The temperature is very low, there is white gas rising under the black umbrella, the man is holding a freshly lit cigarette, his skin is a little dark, the stubble on the side of his mouth has not been shaved for two days, he is holding the cigarette, his hand habitually touches his chin, his white eyes are bloodshot, he has not closed his eyes for two days, he is very tired, but he can't rest, because the murderer is still committing murder.

No. 126 Chunqiao Street, Fuyi Hardware Store.

Three police cars parked on the side of the road, a cordon was set up in front of the hardware store, and after receiving the alarm, Group A of the criminal investigation detachment immediately rushed to the scene, and the captain Chen Yanqiao had just returned from the previous case and immediately rushed to the scene.

A black off-road vehicle stopped on the side of the road, the door opened, and the man in the car wore a black windbreaker, black leather boots, black leather gloves, and a black umbrella, stepping on the rain and walking to Chen Yanqiao.

"Team Chen."

Bai Xiaoci patted Chen Yanqiao's shoulder, Chen Yanqiao was staring at the door of the store, and when he saw Bai Xiaoci, he was stunned for a moment, and then threw the cigarette on the ground and habitually stepped on it.

"How? What did you find? Chen Yanqiao asked eagerly.

Bai Xiaoci shook his head slightly, the murder weapon used by the murderer of the 826 serial murder case was very special, and there were serious scratches on the remaining limbs of the four deceased, and after examination, it was found that the depth of all the scratches was very deep, not ordinary scratches, but injuries caused by murder weapons similar to iron claws.

This kind of iron claw-like murder weapon is very rare, Bai Xiaoci guessed that it was likely to be a weapon similar to the "Divine Eagle Iron Claw", this kind of strange weapon is very operable, and only trained martial arts people can use it.

The injuries of the four deceased were similar, except for the old man who died due to cardiac arrest, the others died of excessive blood loss, the victim was destroyed by the murderer with this "iron claw" murder weapon, resulting in a large number of wounds on the body, but each wound will not be directly killed, due to too many bleeding points, the victim will be in a state of extreme pain before death, and finally in fear and pain, excessive blood loss and death.

The particularity of the murder weapon, the professionalism of the murder process, two clues prove that the murderer is a special group, Bai Xiaoci deduced that it is very likely that he is a martial artist, so he went home to inquire about the clues about the "iron claw" weapon.

"Let's go inside, the case here is very similar to the 826 case." Chen Yanqiao sighed, thinking that Bai Xiaoci would bring good news.

The two crossed the cordon and entered the hardware store, it was now 11 o'clock in the morning, the roller shutter door of the hardware store was ajar, the glass door was very complete, the goods on the first floor were also placed neatly, there was no trace of a fight, and the crime scene was on the second floor.

The first and second floors are connected by an iron corner staircase with a red carpet, but there is still a dull sound of footsteps when you walk on it.

The second floor consists of a living room, a bedroom, and a bathroom, and the compartment opposite the staircase is the bathroom, and when you come up, the door of the bathroom is open, and the space inside is not large, barely able to accommodate two people, there is a washbasin and a toilet, and the wall behind the toilet is a small square window.

The living room was cluttered, with a small amount of blood on the tiled floor and obvious drag marks.

Chen Yanqiao said: "The preliminary judgment is that the murderer sneaked in, and the victim was watching TV on the sofa in the living room at the time, and the murderer first made the victim lose the ability to resist, and then dragged the victim who had lost the ability to resist to the bedroom to carry out the second assault." As in the three cases of 826, the doors and windows of the crime scene were intact, and there were few traces of a fight at the scene, and the victim was seriously injured almost with a single blow, and then tortured and killed. ”

There were also three police officers at the scene who were taking pictures and fixing them, some of the water cups and sundries on the coffee table fell to the ground, the coffee table was also pushed away, and there were residual blood stains on the back of the sofa.

The victims of the 826 case all had marks of severe injuries to the head, and the killer would stun the victim first.

There was a strong smell of blood in the bedroom, the body had been moved, and both the forensic and trace examiners had examined the scene, and the situation was basically the same as in the 826 case.

"This is the personal information of the deceased and the results of reconnaissance at the scene." Chen Yanqiao handed over the computer to Bai Xiaoci from another police officer.

The deceased, Guo Ling, female, 49 years old, was the owner of a hardware store in Fuyi, and divorced her husband Niu Fuyi by agreement at the beginning of the month, and the hardware store was the result of the divorce property distribution.

Bai Xiaoci browsed it, and the forensic doctor identified that the deceased died due to excessive blood loss, the murderer's anti-reconnaissance awareness was very strong, there were no fingerprints left at the scene, and the only breakthrough discovery was a half-mutilated shoe print. The scene of the 826 case was very chaotic, and there were not even footprints that could be used to determine the characteristics of the murderer.

Bai Xiaoci took a cursory look at the scene, found no other valuable information, and the two moved to the window at the staircase.

"What did Shen Li say?" Bai Xiaoci asked, Shen Li was his friend and a trace appraiser.

"The murderer is not wealthy, he is between forty and sixty years old, and he is a middle-aged man with a thin body, about 1.7 to 1.8 meters." Chen Yanqiao fumbled in his pocket, took out a box of "Hongta Mountain" from his pocket, opened it and found that it was empty, he crumpled the cigarette box into a ball and stuffed it back into his pocket.

It can be seen that Chen Yanqiao is very irritable, four people in the 826 case, one person in the hardware store, and five people have been killed, but so far there is basically nothing except this shoe print.

Bai Xiaoci took out a box of "Nanjing" from his pocket and handed it to Chen Yanqiao, Chen Yanqiao took it and took out one, lit it and took a deep breath, "Here, you kid is still rich." ”

Bai Xiaoci smiled, he was not addicted to smoking, and he had to smoke a box of "Nanjing" fine cigarettes for four or five days on weekdays, and he also accompanied one and opened the window with his hand.

Chen Yanqiao has been engaged in criminal investigation work for nearly 30 years, and has solved countless cases, and his addiction to smoking has also been developed in this complicated and tedious investigation process, because he has been punished for smoking at the scene of the crime, but this habit cannot be stopped, it seems that only in this way can his thinking be clear enough.

"There is nothing left at the scene of the 826 case, and there is still half a shoe print here, which can be regarded as a breakthrough discovery." Bai Xiaoci comforted.

Chen Yanqiao shook his head and said: "Xiao Shen said that the shoes worn by the murderer are not expensive, and the sole pattern is seriously worn, the murderer should be engaged in some coolie work, the span from forty to sixty years old is too large, this age group is still in the prime of life, it is difficult to determine the type of work that the murderer is engaged in, and the most troublesome thing is that the surveillance in this store is bad, and the surveillance at the nearby street intersection has not taken useful clues." ”

"Didn't catch the surveillance?" Bai Xiaoci felt incredible, the 826 case happened in Weng County, there is no monitoring in the small county town, but there is monitoring at every street intersection here, and the murderer wants to avoid monitoring unless he steps on the spot in advance, but the murderer of the 826 case is a random killing, and the 826 case is only two days to this day, how can the murderer be so familiar with this place in such a short time?

Seeing Bai Xiaoci subconsciously holding his glasses and looking focused, Chen Yanqiao knew that Bai Xiaoci must have thought of something, "Did you find something?" ”

"It's not certain yet, the murderer had no pattern when he committed the murder in Weng County, so I suspected that he was random in selecting the victim, but in this case, the murderer successfully evaded all surveillance, and this was obviously the action that started after conducting a scene investigation, that is, he committed the murder with a purpose this time, so in this case, will there be any difference between the hardware store case and the 826 case? Or did we just not find the connection between the three cases of the 826 case before? ”

The killer was well aware of the hardware store's surroundings, either because he was a frequent visitor or because he carefully surveyed the surroundings before committing the murder.

The 826 case is assumed to be a random murder, but the hardware store case may be a murder, from the murderer's modus operandi, the hardware store case and the 826 case were committed by the same murderer, so does it prove that the three cases of the 826 case were also intentional murders, but the connection between the deceased and the deceased in the three cases was not found.

Chen Yanqiao nodded, "At present, no significant connection has been found, we have investigated the four victims of the 826 case, you see, first Lin Xueying." ”

As he spoke, Chen Yanqiao called up the information about Lin Xueying in the computer.

"Lin Xueying, female, 15 years old, from Xinshi Village, Weng County, studying in the city's No. 36 Middle School, the time of death was at 6 p.m. on August 26, the place of the crime was at her home, we visited her school, through her teachers and classmates, Lin Xueying is a good student with excellent grades in school, and gets along very well with her classmates, because it happened to be during the summer vacation, the deceased had been at home before the crime, and on the day of the crime, she also asked her classmates to go to the museum on August 30, and her parents were working in other places, There are only two people in the house, her and her grandmother.

Through the analysis of the deceased's family background investigation, this is a very ordinary family, her parents rely on selling coolies to live, and they are also very kind in the village on weekdays, and she is also very well-behaved and sensible, and she did not provoke anyone in school. ”

Chen Yanqiao threw away his cigarette butt and called up the information of the second case.

"The two deceased in the second case are friends, the place of the crime is in the Ping'an community of Wengxian County, in the home of the deceased Cui Bin, the deceased Cui Bin, male, 39 years old, runs a small supermarket in Wengxian County, divorced his wife three years ago, and now lives with his 13-year-old son, the other deceased Wang Ke is his high school classmate, 39 years old, on the day of the incident, Wang Ke actually went to Cui Bin's house to send invitations, Wang Ke actually divorced his wife two years ago, and now it is a second marriage, according to Wang Kejing's fiancée, Wang Ke and Cui Bin have a good relationship, At the beginning of the year, Cui Bin also borrowed 50,000 yuan from Wang Ke, and this time Wang Ke actually came to the door to deliver invitations, which also meant to ask for debts.

At the time of the crime, there were only two of them in the room, Cui Bin's son happened to go to cram school and was not at home, Wang Ke and Cui Bin were killed in the room one after another, we found their mobile phones at the scene, and the mobile phone messages had a record of Cui Bin transferring money to Wang Kejing, that is to say, they talked very happily with each other and there was no dispute, but the two men who were in the prime of life were ambushed and killed by the murderer alone.

Combined with the discovery of the hardware store scene, the murderer's age is older than Cui Bin and Wang Ke, but he can fight with one against two, and Wang Ke actually went to find Cui Bin is a random event, assuming that the murderer's target is Cui Bin, Wang Kejing's sudden visit will inevitably disrupt the murderer's plan, in the face of two adult men, the probability of missing is very large, but the murderer has not changed his murder plan, not only killed Cui Bin, but also persecuted Wang Ke to death by the same means.

The murderer's first target is Cui Bin, we found after investigating Cui Bin's family background that Cui Bin is an honest man, his neighbors also say that Cui Bin is a good person, the main reason for his divorce from his wife is his wife, his son is also very kind to his father, although he will nag him, but he has never beaten him, he is also a duty when he runs a supermarket, and he is very enthusiastic about customers.

Such a person was brutally killed by the murderer at home, and Wang Ke only ran into it by chance, and it was also difficult to escape death. ”
