"Secretary Meng, the Yellow Bureau, the Song Bureau, don't hide it, I'm here for these murders. In fact www.biquge.info there are not only these 4 cases, but also the 5.21 and 7.29 cases. ”

Han Bo walked to the white blackboard, picked up a pen, and quickly wrote down a few dates.

Feeling that this was not very intuitive, he took out a stack of photos of the victim and key evidence from the file bag in front of Xiao Ge, and fixed the photos under the date with something similar to a magnet under the white blackboard.

"The bystanders are clear, but the authorities are confused. Since this series of murder cases were investigated by the sub-bureau and the county bureau, the leaders may not have noticed that there are some commonalities in these cases. For example, the victims are all homeless, and the way to lock the suspect through physical evidence at the scene, and there is a certain pattern in the time of the crime, with an average of two months. ”

Secretary Meng didn't know much about business, so he didn't react for a while.

Deputy Director Huang and Deputy Director Song froze, they were really fans of the Qing authorities, they really hadn't thought about this before. Ying Chengwen, the leader of the criminal investigation detachment, gasped even more, staring at the white blackboard and couldn't believe that all this was true.

"The tools used to commit the crime are fruit knives, daggers, machetes, and bricks, which seem to be extremely random. None of the tools of the crime were thrown into the river, and none of the tools of the crime were confessed by the suspects, and they were all easily discovered by the investigators investigating the scene or searching the suspect's residence. ”

Han Bo pointed to a photo on the white blackboard and said with a solemn face: "There is also DNA, the blood stains of the suspect on the victim's body and the murder weapon, or the items stained with the victim's blood from the suspect's residence, can all be verified by each other." All six murders were caught within a week, and the fastest one took only 19 hours, and although the evidence is conclusive, it is difficult not to be suspicious. ”

Secretary Meng understood as if he had been empowered, and asked the letter: "Han Chu, are you saying that we are mistaken, the murderer is someone else, and all those who are caught are framed and blamed?"

"There's no hard evidence, I'm not sure. As a deputy division-level investigator of the Criminal Investigation Corps, I could not remain indifferent to this, so with the support of the leaders of the corps and even the leaders of the department, I asked Comrade Zhou Suying, deputy head of the Criminal Police Detachment of the Nangang-City Public Security Bureau and director of the Criminal Technology Center of the Nangang-City Public Security Bureau of Jiang Province, to bring equipment over and conduct polygraph tests on several suspects in the name of investigation.

The polygraph results showed that the suspects in the 1.05, 3.12 and 7.21 cases did not speak on the question of whether they had killed someone. The reason why polygraph conclusions cannot be used as evidence is that the accuracy rate of polygraph cannot reach 100%, but there is no such large error. ”

This is a homicide case, not other cases, the murderer is sentenced to death, and a light sentence is also a suspended death!

Secretary Meng realized the seriousness of the problem, frowned, and stopped talking, it was difficult to accept all this. Deputy Director Huang and Deputy Director Song looked at Ying Chengwen together, as if asking him if there was any problem with these cases.

I knew that they didn't mean to drink alcohol, but they didn't expect to make such a big deal.

Ying Chengwen was shocked, took a few deep breaths in a row, calmed himself down as much as possible, and quickly recalled the facts of these cases, the more he thought about it, the more he felt that there was no problem, and subconsciously asked: "Han Division, what about the 12.28 case?"

"The suspect is a psychopath, and polygraphs are useless to him. ”

"The other two. ”

"Miao team. ”

Han Bo looked at the old detective and returned to the conference table and sat down.

Miao Wentao knocked on the cigarette ash and said slowly: "Leaders, we have carefully studied the case file, and we have also gone to the scene to see it today, and even asked several insiders on the record, and found a situation that we did not grasp before, and it should be said that it was not reflected in the case file.

The first is the identity of the victim, Peng Dengfu, the victim of the 5.21 case, is not a homeless, just a bachelor with a difficult family. When the farm is slack, it is sold for money, the clothes are not exquisite, and the person does not pay attention to hygiene, the clothes are tattered, and the body is dirty, and he looks a bit like a homeless man from the outside.

Zheng Qinghua, the victim of the 7.29 case, was also not a homeless person, but a rural woman who ran away due to family conflicts. Away from home for many days, with no money on him, and unable to find a job because of his lack of education, he looks a bit like a homeless person, so he can't be compared with several other murders. ”

As long as it is a homicide, Ying Chengwen has been to the scene almost all of them, has guided the investigation, knows the case very well, and is convinced that there is no mistake, and wants to eliminate the problem that the provincial department thinks is problematic from these two cases.

He lit a cigarette and asked quietly, "Team Miao, do you think there is a problem with these two cases?"

"I wasn't sure before, but now I'm sure it's okay. ”

Miao Wentao looked back at Han Bo and said, "The reason why Peng Dengfu was killed was because he crossed the line by picking up rags and had a conflict with several other people who picked up rags, and one of them made a move, and he lost his life because of a little rags. Although it is not a crime committed by multiple people, it is similar to a crime committed by multiple people, there are witnesses, the facts are clear, and the evidence is conclusive. ”

"The reason why Zheng Qinghua was killed was because she was sleeping in the open because of family conflicts and running away, the whole person's mental state was very poor, her eyes were dull, her body was dirty, and she was uneducated, she looked a bit like a mentally retarded, and she was targeted by Yang Minggao, a trafficker, who was also a suspect who was arrested, and was killed when she resisted. ”

The material was told without even looking at it, and it was not bad, and they had obviously done their homework beforehand.

Anyway, this is also an affirmation, Secretary Meng's face looks better.

Ying Chengwen was not so optimistic, handed over a cigarette, and asked, "12.28 case?"

"Ladies and gentlemen, I personally feel that there are many doubts in this case. The suspect Li Chao is indeed mentally ill, and he did hurt people when he was ill before, but he can't be sure that he is the murderer because he has the victim's blood on his body, because the crime scene is within his usual range of activities, he has nothing to do all day long, wandering around, and it is normal to inadvertently see and even turn over the body. ”

Miao Wentao opened the folder, took out a stack of transcripts, and said bluntly: "Judging from the transcripts, the case-handling personnel are suspected of inducing confessions. He's mentally ill, he's crazy, he doesn't have the concept of breaking the law in his head at all, and if you ask him if he's ever killed someone, he might think it's something to be proud of, and he might claim that he didn't kill anyone. ”

Lao Fei coldly burst out a sentence: "Ten neuropaths, nine like to talk big, and his confession can't be easily accepted." ”

However, there were indeed traces of the victim's blood on his clothes. ”

Han Bo held up a photo and took over the conversation: "Ying detachment, if a person is determined to be a murderer based on blood alone, then I can catch another one within 24 hours." A search of his home led to the discovery of bloody clothes that were also stained with the victim's blood. ”

The photo shows a brand-new floral tie, which was found during the investigation of the scene, and should be in the criminal police brigade of the Chengdong Branch at this time.

Ying Chengwen went to the scene of the crime, saw this tie, looked at Han Bo's confident appearance, and asked nervously: "Han Chu, you're not joking, are you?"

Who dares to joke on this issue!

Two hours ago, Han Bo didn't dare to say this big sentence, but now he dares to say it because several people who went out today were also divided into two ways, Xiao Ge and Section Chief Yu finished investigating the scene of the 12.28 case in the morning, and traced the tie to the owner in combination with the surrounding environment of the scene, and found it.

Xiao Ge tacitly took out a map of Dongping from his bag.

Han Bo took the map, spread it out on the conference table, and marked the crime scene or the location of the body dumping scene in the 1.05, 3.12, and 7.21 cases with a pen.

Touching his pocket, he took out the sewing kit he took from the Pingguang Hotel room, wrapped one end of the thread on the pen, and pressed the other end on the marked position, taking the crime scene as the center of the circle, and drawing several circles in a row when the compass.

"Secretary Meng, Huang Bureau, Song Bureau, the murderers of the first three murders were all captured within 1.5 kilometers of the crime scene. With the mentality of trying it out, I locked the murderer of the 12.28 case within 1.5 kilometers of the dumping site, and used the tie as an important physical evidence to guide us to find the murderer in the same way as the previous three murders. ”

At that time, the "martial madman" was caught, and the "martial madman" claimed that he had killed someone and that there were traces of the victim's blood on his body, so he did not continue to investigate, and now it seems that this is a major negligence.

Ying Chengwen was stunned, and a layer of fine beads of sweat oozed from his forehead.

Secretary Meng, Deputy Director Huang and Deputy Director Song looked at each other, silent, but couldn't help but think about how this matter should end, and if the murderer was someone else, how to explain to the relatives of the "martial madman" next.

"Section Chief Yu, could you please introduce today's findings? Han Bo put down the simple compass and sat back in his chair again.

"Yes. ”

won the first battle, and Lao Yu was really a little excited.

You must know that it was just speculation before, just suspicion, and there was no evidence that could be used at all, and now although there is no same, it can at least prove from the side that there is a murderer who is planting the blame.

He took out a digital camera from his bag, pulled out a photo of an adult man, walked around the conference table to Secretary Meng's side, leaned over and said: "Secretary Meng, this person's name is Wang Yunhai, 31 years old this year, he opened an audio-visual product store near the intersection of Xinping Road and Nanguan Road, mainly selling and renting DVDs.

He pays more attention to his personal image, his hair is meticulously combed, he usually likes to wear a suit and tie, and he is more famous in that area, and many people even laugh at him behind his back, saying that he looks fake. The victim, Cui Jinyuan, not only picked up rags but also begged, often begging in the areas of Xinping Road and Nanguan Road.

Many shop owners see that he is pitiful, and they may also think that he is dirty and smelly, and they are worried about affecting their business, so they give him one or two yuan more and a few cents less, and send him away. Wang Yunhai never gave him money, Cui Jinyuan remembered it in his heart, he didn't dare to act during the day, and ran to the door of Wang Yunhai's store at night to and pee, but was seen by a neighbor.

Wang Yunhai was very angry, and he once beat Cui Jinyuan because of this, and many shop owners around him knew about it. In order to confirm that Wang Yunhai had a certain connection with Cui Jinyuan's murder, Xiaoge and I went to several shopping malls in the afternoon and bought a tie that was exactly the same as the one at the scene of the crime.

I went to his store with a tie, talked to him with a rented video, and deliberately let him see the tie, but he took the initiative to say that there was an identical tie, which was later missing. Dafa sighed, saying how bad the current law and order is, even the person who went to rent the video took the sheep and stole the tie while he was not paying attention. ”
