Three days passed, and the battlefield was transferred from Donghu Town to Tongqing Township, where the victim's mother's home was located, and then to Dingmo Township, where the mother-in-law's family was located. The headquarters moved again and again, until it was moved to the current criminal police brigade of the county public security bureau, and a lot of manpower and financial resources were used but nothing was found.

Even Jiang Yi, who had trusted him so blindly, was almost desperate, took the fax that Wang Siqiang had just sent from Jiangcheng, walked into the conference room and said cautiously: "Master, this is the last six, Team Wang and Inspector Zhou can confirm that they have no time to commit crimes." ”

As long as it is an adult man who goes out to work or do business, he must confirm his whereabouts on November 6 last year, especially in Jiangcheng or not far from Jiangcheng.

This workload was very large, from more than 3,000 people at the beginning, gradually shrunk to more than 200 people, and the Chenguan County Public Security Bureau and the Jiangcheng City Public Security Bureau Xijiao Branch did a lot of work, and issued no less than 60 notices to the brother public security organs to assist in the investigation. Although it has been seen from the household registration information that none of them are murderers, Han Jun still gritted his teeth in order to make sense of Yiqiē.

What puzzled him was that among the so many people who went out to work and do business in the three townships, none of them were murderers, could it be that the previous speculation was really wrong?

Ma Chunlan knows the murderer, they should know each other very well, although she is the owner of a clothing store and has more contact, but the scope of activities is so large. In addition to going to Jiangcheng to buy goods, he almost never left East Lake, after all, it takes patience to open a store and do business, and the business of fishing for three days and drying nets for two days will definitely not be good, and this was confirmed in the investigation.

The murderer must be Chen Guanren, Han Jun was convinced of this, so he simply didn't do anything, asked the Qin brigade to pull a network cable, and sat in the conference room to slowly check the household registration information.

"Master, master."

He clicked the mouse and said nothing, Jiang Yi thought he was in a bad mood, and whispered comfortingly: "Master, we have done our best, and we are not embarrassed in Jiangcheng." When he was outside just now, Qin Da also said that your speculation is very reasonable, and he also thinks that it is more likely that an acquaintance committed a crime, but we were unlucky not to find out. ”

Han Jun stared at the computer monitor and asked lightly: "Since it was an acquaintance who committed the crime, why can't you find it?" ”

"It is possible that the murderer is not from Chen Guan, but has only stayed in Chen Guan and dealt with the victim. It may also have moved, not in the three townships we investigated, but now more and more people from rural areas are buying houses in the city, and maybe even the hukou has moved away. ”

The murderer was dressed in a very ordinary, even shabby, not like a person who could afford a house. But Jiang Yi's unintentional words still made Han Jun's eyes light up, and he pointed to the computer and asked: "Jiang, what other circumstances do you say will move or cancel your account in addition to buying a house and going to school normally?" ”

Jiang Yi said: "There are three situations, one is a black household, such as violating family planning regulations and giving birth, and has not been registered for fear of paying fines; The second is that when a person dies, he will naturally cancel his household registration when he dies; The third is to be sentenced to prison, but he will be re-registered after his release. ”

The murderer is not young, and he is certainly not a superchild. The killer appeared to be healthy, and he probably didn't die so quickly after a few months.

A prisoner who is serving a prison sentence is also unlikely to commit a crime, unless he escapes from prison and absconds to Jiangcheng, or is arrested for some other reason after committing a crime, and the public prosecutor's and judicial departments have to go through all the procedures in just a few months, throw him in prison and cancel his household registration. But if these two possibilities are true, then the murderer's motive is easy to explain.

Han Jun's eyes lit up, and he suddenly got up and said, "Jiang, please come over for a while." ”

"Yes."

The Bureau of Justice has already received troops, and the police officers who assisted him in his investigation have also been sent back to their respective squadrons, Qin Ziqiang directly thought that he was also preparing to go home, and said with a smile as soon as he entered the door: "Investigator Han, the Yellow Bureau just called me, saying that there was no time to get together for the investigation a few days ago, and today is not busy, you have to appreciate it anyway, let him do his friendship as a landlord." ”

Han Jun beckoned him to sit down, and said with a smile: "With so many police forces and manpower, and such a big battle, the case will not be solved and there will be no shame." As the captain of the Criminal Investigation Brigade of the County Public Security Bureau, you should be well aware of all the criminal cases in the county in the past six months, such as those transferred to the procuratorate for prosecution and sentencing, and the prison re-education through labor department asking you to assist in the arrest of fugitives. ”

Qin Ziqiang reacted, frowned slightly and asked, "Investigator Han, are you saying that the fugitive committed the crime, or the person who has been arrested and sentenced has avoided the serious and concealed the facts of the crime?" ”

Han Junzhong nodded his head and confirmed with a stern expression: "We are three feet away from digging into the ground, and I can't imagine any other possibilities." ”

He really wanted to go crazy to solve the case, and he would come up with such a ridiculous idea.

But it is understandable that he ran over ambitiously, wanting to help his apprentice solve a case and show his face, using so many manpower and financial resources, just like he said himself, he was almost three feet off the ground, how could he go back in such a disgraced manner?

Qin Ziqiang sighed secretly and groaned: "There are no fugitives, at least we are not fugitives from Chen Guan, and there are many who have been transferred to the procuratorate for prosecution." However, under normal circumstances, it takes more than half a year to complete the procedure, and if there are several supplementary investigations back and forth, it will drag on even longer, so it seems that only seven people have been caught and completed the procedure in the past six months.

A fraud, the facts are clear, the evidence is conclusive, and it will be done in four and a half months; One is committed six years ago, suspected of theft and intentional wounding, and has been absconding, and the co-defendants have long been arrested, and one of them seems to have been released. The facts are clear, and the procedure goes relatively fast......"

These seven people have no household registration information, and they have already been imprisoned, so they will naturally not be included in the list of people who go out to work and do business during the dragnet investigation.

Han Jun asked eagerly, "Do any of them live in Donghu Township, Tongqing Township, or Dingmo Township?" ”

Qin Ziqiang thought about it for a moment and said: "There really is one, surnamed Zuo, called Zuo Jianhua, who is a wanted criminal for theft and intentional injury six years ago. The family lives in Tongqing Township, but he was arrested in Hui Province, not in Jiangcheng. ”

"When?"

"It seems to be not long before New Year's Day, yes, before New Year's Day, I personally arranged for someone to accept it. Afraid that it would be unsafe to take the train during the peak transportation period on New Year's Day, Lao Wang, Xiao Wu and Lao Zhang of the Third Squadron were specially asked to drive the car. ”

Han Jun asked again: "How did you get caught?" ”

"Everyone who does our line of work is the same, before New Year's Day, before the Spring Festival, and before the two sessions, there will be a rectification of the jurisdiction, and he was arrested when the local public security department rectified it. It is said that he opened a small restaurant in an urban village, not only did he not have a temporary residence permit, but even his ID card had expired, and he did not look like him, and when he was interrogated, he was confused, and the police at the police station felt suspicious, so he took him to the police station to check, and sure enough, he was a fugitive wanted on the Internet, and the ID card was real, but not his own. ”

Han Junqiang suppressed the excitement in his heart, and said half-jokingly: "Team Qin, do you have any photos of him here, there are surveillance records of the clothing wholesale market and its surroundings in Jiangcheng, and there are DNA samples of suspects, if they can be compared, then we will be lucky." ”

"There are photos, but I think it's very unlikely, after all, there is no such coincidence in the world."

When he asked people to turn out the photo and put it on the conference table, Han Jun smiled, smiled happily and brightly. Qin Ziqiang thought that he had really read the surveillance records, and asked with an incredulous expression: "Researcher Han, it can't be so coincidental, right?" ”

Han Jun didn't answer his question directly, but got up and said with a smile: "Brigade Qin, please help me tell you the Yellow Bureau, and by the way, help me tell Director Xin, Deputy Director Shen, and Deputy Director Chen of the Judicial Bureau, as well as Secretary Ge of Donghu Town, Secretary Wang of Tongqing Township, and Secretary Liu of Ding Mo Town, just say that I have a treat tonight." ”

Jiang Yi asked in surprise: "Master, is it really him?" ”

"Just compare the DNA, anyway, he's in prison, and he can't run away if he wants to."

Qin Ziqiang slapped his forehead with a "snap", and muttered: "There is a time to commit the crime, there is a motive for the crime, and during the interrogation, I couldn't explain the experience of being on the run for six years, so I must have hidden something." Researcher Han, we were careless, if it wasn't for your reminder, we would have almost let him succeed. ”

Han Jun patted him on the arm and said with a smile: "It will take time to find the prison where he is serving his sentence, and it will take time to collect DNA samples for comparison, and it is too early to make a conclusion." But we can investigate from the side, such as how far his family is from the deceased's mother's house, whether he knows each other, what is the relationship, if they can all match, I think it should be eight or nine. ”

It's been embarrassing enough in the past few days, Jiang Yisheng was afraid that his judgment would be wrong again, so he couldn't help asking: "Master, the motive for the crime that the Qin brigade said means that he was accidentally met and recognized by Ma Chunlan, who went to Jiangcheng to buy goods, for fear that she would kill people if she reported it?" ”

"Yes."

Without waiting for Han Jun to speak, Qin Ziqiang blurted out: "During the interrogation, we found that before he was arrested, he always thought that the person he slashed with his accomplices six years ago was dead, and he didn't dare to inquire about it for so many years for fear of crime, and he didn't even dare to contact someone with a Chen Guan accent, so he had enough reasons to kill Ma Chunlan." ”

Han Jun sighed lightly and said regretfully: "Maybe Ma Chunlan also persuaded him to turn himself in, telling him that some of those people had been released, but he wouldn't believe it." Of course, it will not be revealed on the surface, and even took the initiative to help Ma Chunlan see the delivery, but in fact, he has already had murderous intentions. ”

The results of the side investigation are very encouraging, and the Tongqingxiang Police Station reported that Zuo Jianhua and Ma Chunlanniang not only live in the same village and the same group, but also have a good relationship between the two families. In other words, Ma Chunlan is easy to believe him, after all, no matter how bad he is, he is bad to outsiders, and it is not a big crime to commit it, how can he hurt her neighbor who has been very good before she got married.
