People's discriminatory glances and words are sometimes more than the sum of their axes.

Night covers the whole village, like a hooked crescent moon hanging in the sky, which can illuminate itself, but cannot bring light to the earth.

A house was lit by a faint light, a woman in the house was lying naked on the floor, her mouth stuffed so that she could not make a sound, a man pressed against her and did things that were not as good as beasts, there was no pain or fear in her eyes, only a sad numbness.

Xu was annoyed by her numbness, he was clutching and biting on her, he wanted her to react, but she was as numb as ever, as if she was laughing at his incompetence.

The flames of anger did not go out but burned more and more fiercely, burning his reason, and finally he took out the murder weapon that he had been planning for a long time, and at the moment when the fatal blow was about to fall, she looked out of the door and shed the last tears.

·····

After graduating with a master's degree from the Public Security University, Wu Rui gave up the opportunity to stay in the capital, and resolutely chose to return to the city where he was born because of his relatives and lovers, familiar streets, and because of his dreams, he used his own learning to protect the city.

Wu Rui majored in criminal psychology at the Public Security University, and after returning to Youcheng, he applied for the police civil service examination, because during his college years, he and his mentor helped crack two major cases that are famous throughout the country.

Oil City has the country's largest oil field, located in the north of the motherland, January is the coldest time, at this time there is more than a month before the Spring Festival, people who have done public security work know that the Spring Festival is around the "two robberies and one theft" and other cases of high incidence period.

'Take the opportunity to go home for the New Year' is the common mentality of some criminals, in order to let people spend the Spring Festival in peace and prevent trouble, the city's police officers have begun to be nervously busy.

Wu Rui and the members of the serious crime team had just arrested a suspect who deliberately wounded people, and before his butt was hot, the team leader Xue Zhengnan walked into the office with a grim face.

Sure enough, a vicious homicide occurred in Yongfeng Village, which is under the jurisdiction of Lin County, and due to the complexity of the case, the county public security department requested the city bureau's serious crime team to assist in the investigation, so the seven capable members of the serious crime team immediately set off.

At noon on January 14, 2016, a scream broke the tranquility of Yongfeng Village, a village under the jurisdiction of the oil city, when a woman in the town died tragically at home and her 13-year-old son was tied to bed.

If it weren't for the fact that the child did not go to school in the morning, the teacher called home and no one answered, and the responsible teacher visited the home, I am afraid that the child who was tied up would also have a fear of life.

The deceased called Liu Ying was a widow and lived with her son, the deceased was naked, died on the floor of the bedroom, the death was miserable, the limbs were nailed to the ground in the shape of large characters, the deceased had been sexually assaulted before his death, there were traces of strangulation, scratches on his body, and tooth marks on his chest and sensitive parts.

But this is not the main cause of death, the real cause of death is a large iron drill (note: used to split wood in the rural areas of Northeast China, the shape is similar to a very thick large steel nail hardware store sale), inserted from the mouth and nailed to the floor, resulting in a cranioplatomy and excessive blood loss.

After meticulous investigation of the scene, several valuable fingerprints and valuable evidence such as hairy cigarette butt footprints and mobile phone information were found at the scene of the crime.

Because the child was tied up in his sleep at the time, and the room was dim at that time, he could not see the appearance of the perpetrator clearly at all, and could not make a confession that was conducive to solving the case.

According to the traces left at the scene, the task force quickly formulated an investigation plan, and after a series of investigations and visits, finally locked up six criminal suspects.

After an in-depth investigation, although they were suspicious, there was no strong evidence to point out who the real culprit was, so they could only be temporarily restrained to continue the investigation, and the case was at an impasse for a while.

Due to the seriousness of the case, the sooner the case is solved, the sooner the murderer can be caught, and Hu Bo, the county public security chief, named this vicious case after the time of the victim's death. Named 113 Vicious Homicide.

Hu Bo reported the case to the city bureau for assistance, so the director of the city public security bureau appointed Xue Zhengnan, the head of the serious crime team of the criminal investigation detachment, to take the members of the serious crime team to assist in the investigation.

It takes more than two hours to drive from Youcheng to Yongfeng Village, and all seven members of the Serious Crime Team gathered in the command car to go together, Dayong drove as usual, and the remaining six people adjusted their seats and sat together, each with a customized laptop computer, and Zhang Panpan, the only female member of the Serious Crime Team who was mainly responsible for network assistance, distributed all the information sent by the Linxian Task Force to everyone's computer.

Wu Rui's left thumb habitually drew circles on his index and middle fingers, and his right hand slid the mouse on the keyboard, carefully examining the scene investigation pictures, the autopsy reports issued by the county forensic office, and the confessions of the six suspects who were finally locked, as well as their alibi.

Among them, a person named Yang Zhizhong was the most suspicious, and his semen and fluid were extracted from the victim's body, and his fingerprints were also extracted at the crime scene.

It is worth mentioning that the forensic doctor also extracted the semen and fluid of another person in the victim's body, but he did not find out who left it, and the mixed evidence left at the scene made the whole case even more confusing.

Everyone looked at the information on the computer silently, the atmosphere in the car was very solemn, and after a long time, Xue Zhengnan saw that everyone seemed to have read all the information, and took the lead in saying: "Let's express our opinions!" ”

Akino, who has a straightforward personality and a hot temper, took the lead and said angrily: "This murderer is really a pervert, this is the most perverted murderer I have ever seen." ”

Wu Rui said affirmatively: "This murderer is indeed a psychopath. ”

This is not a nonsense. It is a major characteristic of the murderer.

Lao Zhou said: "I think the county task force's thinking is right, and the murderer should be among these prostitutes." ”

After investigation, Liu Ying secretly did a skin and meat business and had transactions with many people in the village, which is why a large number of fingerprints, hairs and other physical evidence were found at the scene of the crime.

It is these mixed evidence that make the case fall into a quagmire, making it difficult to distinguish which is the evidence left by the real murderer.

"I think so too." Xue Zhengnan agreed, and then changed his words: "However, it cannot be ruled out that the murderer has another person." ”

Xu Dong, who is good at on-site investigation, looked at the information and put forward his thoughts: "Will there be two people doing this case?" ”

"You mean Yang Zhizhong and another semen, fluid, and remnant?" Akino asked rhetorically.

"Hmm." Xu Dong nodded.

"Probably not." Wu Rui explained: "Although there are traces of two people in the body of the deceased, there are only one person's traces and rhythm of the crime at the entire crime scene, and according to Yang Zhizhong's confession, he left at nine o'clock.

The time of the deceased's death was between 11 o'clock and 12 o'clock, and if you extrapolate from this time node, and then subtract the time of the crime, the contact time between the murderer and the deceased was about 10 o'clock, which is also consistent with Yang Zhizhong's confession in time. ”

"But this cannot completely rule out the possibility of him committing a crime." Lao Zhou said: "The clues of this case are the most messy I have ever seen, I am afraid that we will track down them one by one, if the murderer is really someone else, I am afraid that he would have fled long ago." ”

"yes!" Xue Zhengnan sighed and said: "It is precisely because of this that we can't control it at all, and now it has been more than 36 hours since the incident."

If the murderer is not among these suspects, I am afraid that he has escaped from the province now, and the farther he escapes, the more difficult it will be to arrest him, so we must find evidence as soon as possible to lock up the suspect. ”

Everyone present was full of thoughts, Zhang Panpan had been fiddling with the computer before, and then raised his head and said, "I just deciphered several computer systems with monitoring in Yongfeng Village.

In their surveillance video, it was found that Yang Zhizhong appeared in the video at 8:12 and 9:16 on the day of the crime, both in positive and negative directions. If the direction is correct, Yang Zhizhong may not really be the murderer.

Moreover, in these monitoring systems, no other traces were found that night. ”

The nights in the north are very cold, especially in the countryside, people usually go to bed early, so once the surveillance photographs someone during the time period of the crime, that person is the murderer eight or nine times out of ten.

"But this cannot be ruled out that he deliberately left this video and then sneaked back to the victim's home." Lao Zhou, who is experienced in criminal investigation, questioned it.

"It's a possibility." Xue Zhengnan said.

"Do you think the criminal could be from another village? Then Liu Ying doesn't have to be just a business for the people in her village. Dayong, who was driving, said suddenly.

"Yes! Maybe someone from another village did it. Akino agrees.

After listening to Dayong's words, everyone realized that they had been trapped in the strange circle of thinking of the people in the village just now, and a secret person like Liu Ying was doing the business of regular customers, all of them were brought one by one, and the relationship between relatives in the village was complicated, and it was inevitable that people from other villages would go to prostitute and stay overnight, and they had been ignoring this point before.

Thinking of this, Xue Zhengnan frowned and said: "If this is the case, then this case will not be easy to handle, we must delineate a scope and find the right direction from these messy clues." ”

He knew that for this kind of case, Wu Rui usually put forward many constructive ideas according to psychological dynamics, at this moment Wu Rui was staring at the computer and was engrossed, Xue Zhengnan wanted to ask him if he had any new ideas, but he was afraid of interrupting his train of thought, and the atmosphere in the car became heavy again.

After a long time, Wu Rui stared at the photo of the victim in the computer, his breathing suddenly became short, his hands suddenly clenched the computer with a panicked expression, his pupils dilated, his body trembled, and fine cold sweat oozed from his forehead.

"Xiao Wu, what's wrong with you?" Xue Zhengnan was the first to notice the abnormality, and hurriedly shook Wu Rui's shoulder and asked.

"Little Angkor... Xiao Wu··· Wu Rui... ”

The others shouted eagerly and shook Wu Rui.

Dayong hurriedly parked the car on the side of the road, turned around and asked, "Xiao Wu, what's wrong?" ”

In the midst of everyone's shaking and shouting, after a while, Wu Rui let out a breath of turbidity, came back to his senses and returned to normal, gasping for breath as if he had drowned.

"Xiao Wu, what's wrong with you, are you okay? Do you want to go to the hospital? Xue Zhengnan asked with a concerned face.

Wu Rui's throat rolled and swallowed and foamed, and after calming down, he looked at everyone gratefully and said, "I'm fine, don't worry." It's just that I'm too absorbed in thinking about things. ”

Qiu Ye breathed a sigh of relief when he heard this, patted him on the shoulder and said with a palpitating smile: "Big brother, you are too scary, I thought you were doing something wrong!" ”
