Chapter 56 dragnet investigation

During the net clearance operation, the murderer committed the crime against the wind, and the leaders of the county public security bureau were furious, and a large number of police forces were dispatched to carry out a dragnet investigation in the county, and the target of the investigation was a man with a height of 175-185, aged about 35-45 years old, and possibly carrying a backpack behind him. The focus of the investigation is on the villages and towns within a radius of 10 kilometers near Dawang Village, and the police participating in the war are required to ensure that no households or people are missed, and those who are suspected can be brought back to the county bureau for comparison and elimination one by one.

Li Tie took Shao Dong and Wang Bo for a week to conduct a house-to-house investigation in Dawang Village, but did not get any clues, so he had to return to the county bureau to make plans.

Despite the use of a large number of police forces, finding a specific person in a city with a population of one million is like looking for a needle in a haystack.

Wu Wei has made a major breakthrough in technical identification, the DNA extracted from the half cigarette butt left at the scene of Li You's murder, the DNA extracted from the skin tissue left in Zhao Shu's fingernails in the murder of Lu Zhiyong and Zhao Shu, and the DNA extracted from the bloody palm prints on the wall calendar in the serial murder case fifteen years ago, after comparison, were left by the same person, but the specific identity of this person is still a mystery.

The only sound of smoking in the office of the 1st Squadron is the sound of two homicides, three deaths, and the even worse serial murders of many years ago, but the perpetrators of all this are still hiding in the darkness of the city, with impunity.

Everyone in the first squadron is thinking hard about how to proceed next, although it is a painful torture for everyone, but no one will give up easily, because everyone has the determination to uncover the truth.

There are two types of characterization in criminal cases, namely homicide of passion and premeditated murder.

Homicide of passion is a kind of crime of passion in criminal law theory, which corresponds to premeditated murder, that is, there is no motive for intentional homicide, but under the stimulation and provocation of the victim, he loses his mind, loses control, and then kills others.

The murderer in the serial murder case committed 9 cases over a period of 15 years, killing a total of 16 people, which must have been a premeditated homicide for a long time, and was by no means a crime of passion.

Shao Dong took out a piece of paper and wrote on it:

Pan Wende, male, 26 years old at the time of the killing, was a businessman and lived in Dongfeng Street, G County.

Luo Songsong, male, 29 years old at the time of the killing, was a paper mill worker who lived in Group 5 of Luowa Village, G County. Zhang Qi, the wife of Luo Songsong, who was killed at the same time, was 26 years old when she was killed, a paper mill worker.

Chang Weiqiang, male, 30 years old at the time of the killing, film projectionist, No. 3, Zhaohe Village, G County. Liu Xiaoli, the wife of Chang Weiqiang, who was killed at the same time, was 27 years old and unemployed when she was killed. Chang Beibei, 3 years old, the son of Chang Weiqiang and Liu Xiaoli, and the three-year-old child at the scene was also murdered.

Chen Qihui, male, 25 years old at the time of the killing, ran a restaurant with his father on Gongnong Road in the county seat, and was killed in the hotel at night. His father, Chen Aiguo, 49 years old, heard movement while sleeping and went to Chen Qihui's room to check and was killed by the murderer.

Han Haitang, female, 33 years old at the time of murder, shopping mall salesman, No. 112, Tangzhuang Village, Hanlou Town, G County. Han Haitang's son, 9-year-old Zhou Bingbing, was also killed at the same time.

Wang Jianwei, male, 29 years old when he was killed, is a private entrepreneur who owns two companies and specializes in various mp3 and mp4. He lives in Aimin Community, Jianshe Road, G County. Liu Meng, Wang Jianwei's fiancée, was killed at the same time that night.

Li Ming'an, male, 24 years old at the time of the killing, was a tax bureau clerk and lived in the supply and marketing cooperatives of Panlong Town, G County.

The two most recent homicides are:

Li You, male, 28 years old, works in other places and lives in Dawang Village, G County.

Lu Zhiyong, male, 41 years old, village secretary of Dawang Village, living in Dawang Village, G County, was killed at the same time as Lu Zhiyong's wife Zhao Shu, 39 years old, unemployed.

Shao Dong looked at these contents and thought, there must be a motive for killing, and no one would kill so many people for no reason.

But what was the motive of the murderer? Judging from the files of the deceased in the case files of seven cases that occurred fifteen years ago, the ages of the deceased were mostly between 20 and 35 years old at the time. But there is a gap in the identities of these people, and there seems to be no intersection in their lives.

Judging from the time calculation, in the two recent cases, Lu Zhiyong was 26 years old 15 years ago, Zhao Shu was 24 years old, and Li You was only 13 years old at the time.

Shao Dong couldn't figure it out.

…

…

"Master, are you sick?" Wang Bo's words pulled Shao Dong's thoughts back to the office.

Only then did Shao Dong see Li Tie holding a box of medicine in one hand and a water cup in the other, ready to drink the medicine.

Li Tie said with a smile: "It's okay, I'm sick, I'm sick with stomach problems." He opened his mouth and threw the medicine into his mouth, drank it, and then said: "We have been in this line for a long time, and the diet is not regular, many people have stomach problems, and often stay up all night, keep smoking, and when you are older, there are always some problems with your body." ”

"Master, pay attention to your body, work is important, and your body is even more important. Wang Bo said.

Shao Dong got up and said, "Team Li, you can rest for a while." ”

Li Tie looked at his watch and said, "It's noon, let's rest, there are tasks in the afternoon, maybe it will take a long time." Everyone hasn't slept well in a long time. ”

The two responded, Li Tie frowned and walked to the lounge, and after going out, he clutched his stomach with a painful expression, sighed, and staggered.

Shao Dong and Wang Bo looked at each other and smiled bitterly, in fact, every policeman who handled the case had a small wish.

Sometimes this desire can be as simple as getting some sleep or eating a hot meal.

Although these things are very normal and trivial things for ordinary people, they can only be a luxury for criminal police.

In the blink of an eye, in the office, the sound of snoring sounded, and the two of them fell asleep on their desks.

…

…

It didn't take long for Shao Dong to wake up, and he had a dream in which the scene was terrifying, with a masked face that kept laughing at him.

Shao Dong wiped the beads of sweat from his forehead, smiled self-deprecatingly, and opened the file on the table.

I don't know how long it took, Li Tie gently pushed open the office door, patted Wang Bo and said, "Xiaobo, wake up." ”

Wang Bo opened his eyes in a daze, "What time is it?"

Li Tie sat down and said, "It's time, let's discuss the case." The dragnet investigation has no effect, the director asked me what progress I had, I couldn't answer, we can't sit still, Xiaodong, what do you think about this case?"

Shao Dong put down the file in his hand and said: "Team Li, I think we still have to start with the motive for killing, the murderer will not kill for no reason, there must be an unknown inside story in it." Fifteen years ago, what happened is the focus of our investigation. ”

"The difficulty is here, the method you said has been tried many times, you look at the file, these people's identities are different, and the industries they are engaged in are not the same, fifteen years, the society is developing so fast, it is no longer feasible to find clues according to the original address, some even the houses have been demolished, not to mention trying to find neighbors to understand the situation. Li Tie said.

Wang Bo analyzed: "Assuming that these people have a grudge against the murderer, first of all, this assumption is not true, Li You is only 28 years old this year, and he was 13 years old fifteen years ago, how much enmity can the murderer and a 13-year-old child have?"

Li Tie smiled: "That's why I called you up, Li You's parents are back, and they came to the bureau in the morning to find their son's body to see the last time, and I notified him to come over in the afternoon." Let's meet Li You's parents later. ”

Accompanied by the police in the reception room, Li You's parents came to the conference room, the two looked to be in their fifties, Li You's father had red eyes and a haggard face, and Li You's mother was dazzled, as if she was stupid and let her husband pull her away, it can be seen that the loss of a child in old age has caused great damage to the hearts of the two.

Although they don't want to deal another blow to Li You's parents, there is no better way to investigate Li You's death, so they can only try their luck from the two old men.

Wang Bo poured two glasses of water, handed them to the two of them and said, "Uncle and aunt, drink some water, don't be sad, the matter has already happened." ”

Li You's mother looked blankly and blankly, as if she hadn't heard Wang Bo speak.

Li You's father nodded to Wang Bo and said in a dumb voice: "My name is Li Yongqing, I am Li You's father, I want to meet my son." ”

Li Tie explained: "Li You's body is in the technical room, and our forensic doctor also has to extract and collect traces, physical evidence, biological samples, etc. related to the case. It's inconvenient for you to look at it now. Once the cause of death has been ascertained and evidence has been extracted, you can come and collect your son's body. ”

"How long?"

"Within a month. ”

Li Yongqing rubbed his face with his hands, was silent for a while, and asked in a dumb voice, "Have you found the murderer?"

Li Tiedao: "Not yet, but ...... I would like to ask you a few questions. ”

Li Yongqing looked up at Li Tie, took a deep breath and said, "You say." ”

Shao Dong took out a piece of paper from his pocket, which recorded the name of the deceased in the serial murder case, handed it to Li You's father and said, "Do you recognize the person on it?"

Li You's father took the paper, frowned and looked at it, the more he looked at it, the more excited he became, he got up and said loudly: "What do you mean by showing me this thing? I don't know anything! I don't know these people!"

Li Tie said: "Brother, don't be excited, will you sit down first?"

Li Yongqing sat heavily on the bench, panting in his mouth.

Shao Dong said: "Uncle, we are also very sad that your son was killed, but you have to accept the reality, what we can do now is to find out the murderer and ask for an explanation for your son's death." Don't you, as a father, want to find the murderer?"

"What is the use of you police? After more than ten years of searching, have you found the murderer? If the murderer had been found, would my son have died?" Li Yongqing asked.

When everyone heard Li Yongqing say such a thing, they knew that there must be something wrong here, because the two recent homigies and the serial murder case 15 years ago were investigated together, and this news was only known to the first squadron and was not made public.

And Li Yongqing can tell the case more than ten years ago when he opens his mouth, and he must know some inside information.

"You have to cooperate with us to catch the murderer. Shao Dong persuaded.

"Cooperate? How to cooperate? Even if the murderer is found, will my son be able to survive? Ah? Can you?" Li Yongqing was extremely excited.

When Li Yongqing was emotional, no one could answer the questions he asked, and everyone knew the truth that people cannot be resurrected after death.

"Uncle, if you are like this, the only one who will benefit is the murderer. Shao Dong said.

"I'm sorry, I don't know anything! My son's body, after you have extracted some bullshit evidence, inform me, I'll get it! Goodbye!" Li Yongqing finished speaking, and pulled his wife and walked out.

Wang Bo got up and wanted to step forward to stop him, but Li Tie stretched out his hand to stop Wang Bo and shook his head.

As soon as the two left, Li Tiedao: "It's useless for you to stop him now, Xiaobo, you follow them, see where they live, be careful not to let them find out." ”

"Okay, master. Wang Bo said as he walked and followed.

Li Tie said to Shao Dong: "We investigate from the side, from Li Yongqing's life trajectory. ”
