I originally planned to stay at home on the first day of the lunar calendar, and invite relatives and friends on the second day of the lunar calendar. I accompanied my father-in-law and mother-in-law and Li Xiaolei back to BJ on the evening of the lunar calendar. I stayed in BJ for three days and flew directly to Xinyang. I happened to go to work at the lunar calendar in the lunar calendar.

Plans are always worse than change!

After the New Year, you are very likely to go to Xiguang to assist in handling the case. If you don’t have a diamond, don’t take care of the porcelain work. You must hurry up and recharge and be the only thing you want to do is to cram the matter.

After the second year of junior high school, Han Bo sent his father-in-law, his wife, and Xiao Xuxu to the Nangang to BJ flight, and returned home alone to BJ. He studied alone like the postgraduate entrance examination.

DNA technology is a brand new criminal technology, including knowledge of information, medicine, computers and other disciplines, and knowledge is updated and fast. If you want to keep up with the pace of the times, you must learn from the Internet, books, peers, and experts. With enough knowledge reserves, you can use your brain to develop problems, carry out research and forge the killer weapon for solving cases in DNA technology.

Looking at domestic cases and foreign documents, I asked the experts from the "Second Institute" humbly for advice if I don't understand.

I have been tired of reading technical cases and literature, and I studied the case files copied by the provincial department when I came back before the New Year.

Now the criminal investigation department has heavy tasks and great pressure. If the case can be solved, everything will be fine. I have no energy to explore the cause of the case. I will be officially transferred to the Criminal Investigation Corps and can no longer solve the case just like before. It is necessary to study and analyze the social phenomena and deep-seated problems presented by various criminal cases, explore the laws of crime, study which types of cases can be prevented, and which types of cases should be solved after birth.

Compared to dinners that are not played, and eating and drinking, I feel more comfortable doing what I like. Three days have passed without realizing it, and there is almost no one disturbing me except for the occasional phone call.

Perhaps the angles we stand are different, and our views on some cases are also different.

Among the murder cases that were solved in the province last year, Han Bo felt that there were some doubts in several cases, only one of these cases is being handled, and the other cases have been closed.

After reviewing old cases, it is necessary to deny other people's judgment. After several weighings, Han Bo still called Du Zhigang's team on the phone.

"Happy New Year, Team Du."

"Han Bo, isn't you paying New Year's greetings on the first day of the New Year? What's the matter? Are you back early?"

The timing of making this call was carefully selected. Today is the commander of the corps are on duty, which will not affect the leader's New Year. Moreover, the leader can easily access the case files in the unit.

Han Bo didn't want to keep it a secret, nor did he want to delay the leadership's time. He said bluntly: "Council Du, I have been studying last year's murder case files at home these days. The 12.18 case in Dongping City may need to be investigated again."

Du Zhigang had a little impression of the last murder case of a student in the province last year and said, "I know this case. The task force has designated an ordinary homeless man as a murder case. Lao Huang has been to Dongping because of this case, and it seems that it has been solved and the evidence is conclusive."

"The evidence is conclusive from the case file."

Han Bo took a deep breath, stared at the monitor and said, "The initial interpretation of the murder weapon is a fruit knife, stabbing it more than a dozen times, and the means are cruel. However, the method of handling the corpse is simple, and the murderer has not even thought of erasing his traces. The forensic doctor found scratched flesh in the crack of the victim's right fingernail, and he was tightly holding a piece of rag in his left hand."

We must never create an unjust, false and wrong case. The General Team Du did not think that Han Bo was looking for trouble because he was fine, so he subconsciously asked: "Is there any problem?"

"There is no problem with this case itself, and the quality of the case handling should be considered relatively high. The task force's characterization makes sense, but it's not without doubt."

Han Bo put down his mouse, turned on the notes he made, and analyzed: "First, why did the murderer abandon his corpse in the fruit woods? If it was to cover up the crime or delay the appearance of the situation, it would be better to hide in a corner near the first scene? Secondly, the victim is a homeless man, how could such a sloppy man have a brand new tie? Again, since the murderer can think of abandoning the corpse, why didn't he think of cleaning up the blood and skin tissue in the victim's nails?"

"Maybe it was the homeless who killed people because of trivial matters, and they were relatively simple in their minds. It was normal for them to think of some things, but they didn't expect some things."

"The murderer is also a homeless man, a homeless man with mental problems, and even confesses to the facts of the crime. However, on March 12 last year, a homeless man was killed on the grass outside the west gate of Dongping Fertilizer Factory. The deceased was named Chen Daquan, who was stabbed to death by a dagger.

The Pingguang Branch of Dongping Municipal Public Security Bureau showed another person's blood and a button on the deceased. Four days later, the suspect Ding Xinjun was arrested. He had conflicts with the victim, and the blood dna matched, and the button was also on one of his clothes. The investigators found the murder weapon at his home, and the evidence was as conclusive."

These cases are very strange, and Han Bo is as unsure whether he is wrong.

However, since he had opened this and had already said this, he had to believe his intuition. He flipped through his notebook and continued: "I found out from the case file that Ding Xinjun always called for justice after being arrested, and even asked the lawyer who provided him with judicial aid to defend his innocence. As a result, because the evidence chain formed by direct evidence and peripheral evidence could not be refuted, he was sentenced to death by the court."

"There is nothing wrong with this!" Du Zhigang became more and more confused as he thought about it.

"If this case is just one, there is nothing wrong with it. But I have reported that in the past year, there have been four cases of murder of homeless people born in Dongping City, born on January 5, March 12, May and December 18 respectively."

Is the young man a little nervous? Du Zhigang reminded: "Han Bo, homeless people are the seniors in major criminal cases like drug users. It is not surprising that a prefecture-level city has three or four such cases in a year."

"Coalition Team Du, this is just the city."

Han Bo really hoped that he was wrong and said solemnly: "I found out in the revision that the two counties in Dongping City also had a homeless man's murder case last year. They were born at the end of July and in mid-January. The city counted on average two months together."

"There is such a thing!" There were not so many coincidences in the world, and Du Zhigang couldn't help but feel shocked.

"So I think it's very strange. What's strange is not this kind of case, but the time of the case and the way the case evidence locks the suspect, and..." Han Bo had other questions in his mind, but he didn't think so clearly.

Is it really a serial murder case, not only serial murder, but also frame the blame!

Du Zhigang's heart skipped a beat and asked, "Are you killing people with daggers?"

"No, there are fruit knives, daggers, machetes, and bricks, which look very random. But no tool for committing crimes was thrown into the river, and no tool for committing crimes was provided by the murderer. They were easily found by the investigators searching the scene or searching the murderer's residence."

Han Bo clicked the mouse, looked at the physical evidence identification reports on the computer monitor, and said: "There are also DNA. There are blood stains of the suspect on the body and weapon of the victim, or searching for items stained with blood stains of the victim at the suspect's residence. Anyway, they can verify each other."

The crime is born in six or seven years, and the methods of committing the crime are different, and the weapons used are different, but the dead are all homeless people. The way of locking the suspect in the case evidence is exactly the same, and there are certain rules in the case time!

As an old criminal policeman, how could Du Zhigang not know what this means?

He gasped and asked anxiously: "All the suspects were sentenced to death?"

"There are three sentences, and the other three are under procedural procedures. One person is sentenced to death, and is waiting for the Supreme Court to review. One person is suspended for death, and the other person has no life. The lifeless one is named Liu Bo. He voluntarily admitted to the murder, but argued that he accidentally killed the other party when he was forced to helplessly. The judge accepted his confession."

Han Bo rubbed his swelling temples and then said, "I contacted the detention center in the afternoon. According to the police officers of the discipline, he refused to admit it at first. Maybe someone told him through the news that he would remind him that he would not admit it is a dead end. It would be better to admit it, and find a reasonable reason to kill, shirk some of the responsibilities, and maybe he can save his life."

"Where are other suspects?"

"Because time is relatively haste, it is now the Spring Festival. Apart from the disciplinary police officer mentioned just now, I only contacted one of the police officers in another case in the afternoon. He was at the scene when he was arrested, but he was not happy at all, as if he had become an inexplicable accomplice. He felt that the suspect was not like the murderer at all. He was at a loss when he was arrested. Until he was taken to the trial table, he firmly believed that the police had made a mistake and would let him out soon."

"There is no problem for a single case, but if it is connected together, there will be problems."

"It can't be considered a problem, it can only be said that there are doubts."

Du Zhigang habitually knocked on the table and pondered: "If there is some connection in these six cases, it should not be difficult to investigate. It is just based on the existing evidence, not evidence, but just suspicious points. It is difficult to determine that the six suspects were wronged and did not meet the conditions for concatenation."

It is already terrible to make a mistake in one wrong, false and wrong case. What is the concept of six cases at once!

Han Bo knew that the leader was in a difficult situation. He felt that he should come forward to remind him, but he also felt an inexplicable sense of guilt, as if he was denying the judgment of his colleagues in Dongping City.

But thinking of the mission he shouldered, he couldn't help but blurt out: "Coalition Du, life is at stake."

"Yes, this kind of thing cannot be considered in the future. I think of a way to keep people behind the gun first, wait for you to come back to form a special working group, go to Dongping in the name of research, check the truth and check whether these cases are related."

The more you do something like committing crimes, the more flaws you leave.

If these six cases are really related and there is a cunning serial killer, then as long as you identify the direction and thoroughly investigate the social relationship between the six victims, no matter how cunning the real murderer cannot deceive the public security organs. After all, no one can kill people for no reason.

Even if the murderer is a perverted murderer, he has no grudges with the victim and just wants to kill, he will still appear around the six victims. As long as the basic work is done carefully enough, there will always be a way to compare him.

The "work" introduced by the old leader is not very urgent. The bastard who told him to kill others as soon as he went to the execution ground could not escape death, but it was only a matter of day or night.

He has been living for more than two years and doesn't care about letting him live for a few more days.

Several cases in Dongping City are different. We must seize the time to find out the truth, otherwise once the firing is carried out, the suspect who was wronged may never survive.

Life is at stake. Han Bo did not dare to delay for a moment and said, "Council Du, I will go to the East China Sea now. The air tickets for tonight should not be difficult to buy, so there is no need to wait for the seventh day of the lunar month to go to work."

"Okay, book a flight and call me, and I'll arrange for someone to pick you up at the airport."

"yes."

...

At the same time, the staff on duty at the Nangang-Metropolitan Party Committee and Municipal Government Letter and Visit Office, more than ten kilometers away from Binjiang Community, are receiving three very strange petitioners.

People from Jiangcheng came to Nangang to visit, not only did they have relatives of the parties involved, but also a lawyer.

What's even more funny is that they came to complain but didn't even understand the situation. They swear that the captain Han Bo from the Municipal Public Security Bureau had a problem with his lifestyle, and he was confused with a married woman, even knew the law and violated the law, used his power to suppress others, and retaliated against the husband of a married woman.

There are more than a dozen chiefs of the chief and deputy detachment of the Municipal Public Security Bureau. If it were someone else's letters and interviews, Deputy Director Wang of the Office may not know him, but Han Bo is too famous. A cadre who is valued by Secretary Chen of the Municipal Political and Legal Committee and a former star in the city's political and legal system, has cracked several major cases, but which city leader does not know him.

When you come, you have to follow the procedures.

After receiving the reaction materials they provided, asking about the specific situation, and completing the records carefully, Deputy Director Wang looked at each other with his subordinates and asked calmly: "Comrade Zhang Guizhen, you said that Han Bo and your daughter-in-law Wu Na have an improper relationship with each other. At about when did it happen?"

"For many years, everyone in Sihe knows it."

"How many years are there?"

Since you are here to visit, the situation you are responding to must be convincing.

Zhang Guizhen is not a rural woman who has never seen the world. Before retirement, she was also a cadre of an enterprise. She said hatefully: "Before Wu Na went to Jiangcheng to go to school, they had an affair. My son was blind and married this woman with a slutty beauty. Because she often returned to Sigang and had a fool of herself, the two divorced when they had a disagreement."

"When did Wu Na and your son get married?"

...

Zhang Guzhen answered in a slight manner and started talking nonsense.

It is said that there are shrews in the countryside, but it seems that there are unreasonable women in big cities.

Deputy Director Wang was completely convinced. After asking all the questions, his face suddenly changed: "Comrade Zhang Guizhen, you must be responsible for what you said, you cannot make a fuss or slander, otherwise you will have to bear legal responsibility!"

"What does it mean, you officials protect each other?"

"It's still a mess!"

Deputy Director Wang slapped the table with a loud voice: "You react to Comrade Han Bo's problem. Have you ever met Han Bo? Do you know how old he is this year, what history he has, and what unit he works in?"

I just spoke slowly and turned my back on the other side.

Zhang Guizhen was shocked, and Yan Tianbao was so scared that he didn't dare to look up. Lawyer Qian saw something wrong and asked carefully: "Director Wang, do you know Han Bo?"

"You don't know me, I know you!"

During the Chinese New Year, Deputy Director Wang came over and made a fuss. How could Deputy Director Wang give them a good look? He said coldly: "Speak nonsense and pour dirty water on an innocent cadre. I can tell you clearly that time is completely unfavorable! Wu Na often goes back to Sigang and messes with Han Bo? Can she meet Han Bo when she returns to Sigang?

The time you mentioned was that they were studying in BJ; the second time you said, they were being transferred to the south by the Ministry of Public Security to handle the case; the third time was even more a joke, they had been transferred to the Southwest to work. He was a state cadre, a people's policeman, not a god, and could not know how to clone the arts. How could he mess with Comrade Wu Na?"
