Chapter 262: Fingerprint Strategy
Having money or not having money is relative, and the two-story small buildings that looked relatively new and better before that year looked a little old and somewhat fundamentally outdated compared with the small western-style buildings that have been built in the past two years.
Ma Hongfeng and his two older brothers have a house in the city and do not need to live in their hometown. He has been a criminal police officer for so many years, and he knows very well the importance of protecting the scene, the house along the street has neither been sold nor rented, and has been kept as it has been after the investigation by the criminal technical police, the ground and the table are covered with dust, and there are dense cobwebs everywhere.
The faΓ§ade is the living room, the "lobby" of the hotel, with a table of eight immortals, several benches, a sofa that imitates mahogany, and a bar that looks very simple.
Special trade permits and business licenses hang on the wall behind the bar, and a plaque reading "Wealth is abundant" hangs above the door leading to the staircase and kitchen.
Jiang Yi dusted off the cobwebs on the master's body, pointed to the bar and introduced: "Few outsiders come to East Lake, and even if they do, they rarely stay in hotels. Although there was such a place to stay in the town at that time, the business was not very good, with a maximum of ten or twenty guests a month. The charge is very cheap, if you don't turn on the air conditioning, it only costs 40 yuan for a night.
At that time, there was no hotel management system, and it should be manually registered according to the regulations. Maybe the law and order in the town is better, and there are few outsiders who come in normal times, or it may be to see the face of the horse brigade, and the police station is very lax in managing here. The two victims were careless and did not register their passenger identity cards at all, causing great difficulties in the investigation work. β
Teng Yaozhou was stopped by the special police outside and couldn't enter, so he could only stand by the door and say with an embarrassed face: "After the incident, the bureau investigated the responsibilities of the director, instructor and district police, and all of them were dismissed and transferred from their original posts." The deputy director in charge of public security, the captain of the public security brigade, and the instructor of the public security brigade were also punished accordingly. β
Han Jun nodded noncommittally and asked in a low voice, "This is the first scene?" β
"Yes."
Jiang Yi walked to the bar, and with Zhang Xiang's cooperation, he gestured like Qi Zhaoyou: "The investigators found that there were traces of scuffles here, and the female victim may have been strangled to death by two murderers when she was checking out." The time of the crime was about three or four o'clock in the morning, and they moved quickly. The female victim didn't even have time to call for help. β
"What about the male victim?"
"Maybe I slept too hard at the time, maybe I thought it would be okay and didn't go downstairs."
Jiang Yi pulled open the utility room under the stairs and continued: "After strangling the female victim." The two murderers stuffed the body here. According to the autopsy report, they waited at least an hour before attacking the male victim. The murder weapon was a kitchen knife in the kitchen, and when he went upstairs and knocked on the door, he slashed as soon as the door opened, and he slashed thirteen times in a row. The methods are extremely cruel. β
After going up and looking at room by room, Han Jun walked to the location where the male victim was killed, frowned and asked: "The two victims don't have much cash on them, and the economic losses are negligible, is it too arbitrary to judge the murder?" β
Zhang Xiang shook his head and said with a wry smile: "After the case, the special case team investigated all the cases that Ma Hongfeng participated in the investigation and hosted, focusing on the criminals and their families he dealt with, and did not find anything abnormal. At the same time, he investigated the business competitors of his two brothers, and found nothing suspicious.
The three sons of the two victims were all prosperous and filial. Life is going well. Open a small hotel and set up a few pool tables, just to pass the time. Usually amiable, I haven't offended anyone. β
"How did the two suspects get locked?"
"I found that they stayed here for a day or two nights, during which they went out to buy cigarettes once, and few people in the countryside got tattoos, so they had a little impression of the small shop owner opposite. But I've only seen it once, and I only remember that I have a tattoo on my hand, and I can't remember what it looks like. β
Stay here. Han Jun pondered for a moment and then asked, "Did the owner of the small shop say that the suspect who bought cigarettes had any accents." β
"Locals. Local accent. β
"This is strange, the provincial department task force has been stationed in East Lake for more than a year, digging three feet into the ground and turning over the whole county. If the murderer is a local, how can it not be investigated? β
Jiang Yi said with a sad face: "Master, we are strange. They were even more strange, they tried their best, and they couldn't find out what they could do, and they couldn't find even a valuable clue. β
Who would attack two old men who couldn't possibly carry much cash on them, Zhao Zhenxing couldn't figure it out.
Just as he was about to go out to take a breath, Director Han Da muttered: "The murderer stayed here for a day or two nights before making a move, indicating that they were premeditated, or hesitant. The modus operandi is very rough, there is no sense of anti-investigation, so many fingerprints are left, and they don't even take away the murder weapon and throw it away, which shows that they are not habitual offenders, and they may be committing crimes for the first time, so the fingerprints of the ex-offenders can't be compared in the database. β
Jiang Yi reacted like an empowerment, and blurted out: "A first offender may become a habitual offender, and not being able to compare it at that time does not mean that it cannot be compared now." The Ministry of Public Security does not have a fingerprint database of ex-convicts, it does not mean that there is no local fingerprint database, master, I think I know how to check. β
It's a little clear, I have to admit that this girl does have the talent to be a criminal policeman.
Director Han was very relieved, and asked with a smile: "How are you going to check?" β
"Transfer Brother Chao over and let him be in charge of the fingerprint line, and at the same time ask the Criminal Investigation Bureau to coordinate and organize trace identification experts to divide into several groups and rush to several surrounding cities and counties to fish out local fingerprints. We are responsible for the re-investigation of those local people who have left home before the crime and meet the age and characteristics of the two suspects. β
Zhao Zhenxing asked with a puzzled face: "Comrade Xiao Jiang, why don't you investigate those locals who disappeared after the incident?" β
With the encouragement of the master, Jiang smiled proudly: "Director Zhao, we '801' only want to do what the task force didn't expect, and only do what the task force hasn't done." The local people who disappeared after the incident have been investigated and investigated, and it is useless to re-investigate. Only those locals who left home before the crime did not check, and no one can guarantee whether those people came back before and after the crime. Come to think of it, this is probably the only omission from the task force. β
"Migrant workers, sneaking back to commit crimes, and leaving quietly after completing the case, if he has no criminal record, the task force will definitely not include him in the scope of investigation."
"Yes, I can only think of that possibility."
Finding and sorting is the key, and organizing trace experts to fish from the fingerprint database of ex-convicts of the Ministry of Public Security and the local fingerprint databases of surrounding cities and counties is an insurance, and Zhao Zhenxing finally learned the "801" style of handling cases.
Regardless of 3721, first check it on a large scale, on a large scale, and on a large scale, and then talk about it, and then break it if it can be broken. If you can't break it, you can hand it over to the Tracking Division and slowly figure out a way.
However, he thought too conservatively, and in order to ensure that nothing went wrong, Director Han said lightly: "These are far from enough, Director Zhang." It is best to coordinate with the provincial department and the county bureau to carry out a pilot project of fingerprint supplementation of second-generation ID cards. Starting from Donghu Town, radiating to the whole county, the fingerprints of adult men between the ages of 20 and 35 are collected, and others press the collector. Feel free to make up for it.
The work must be detailed, including those who serve as soldiers, go to school, buy a house and move their household registration, one is counted as one, and one cannot be missed. Combined with touching the row, eliminating it little by little, and narrowing the encirclement little by little, I don't believe that I can't get it. β
According to the newly revised Law of the People's Republic of China on Resident Identity Cards, citizens applying to receive, renew or renew resident identity cards shall register their fingerprint information. Citizens who apply for a resident ID card for the first time must have their fingerprints collected when applying; Citizens who have already received a resident identity card. Fingerprint information will be collected when renewing or renewing a resident identity card.
In order to solve the case, it is not impossible to make a pilot centralized supplement, the key is more than 300,000 people in the county, and there are 80,000 adult men if not 100,000, how to compare so many fingerprints collected?
The fingerprint identification system of the Population Management Service Corps is different from that used by the Criminal Investigation Bureau, and the fingerprint information is added to the resident identity card to prevent the fraudulent use of the resident identity card and the forgery or alteration of the resident identity card. It is conducive to the rapid and accurate identification of the identity of the holder by state organs and financial, telecommunications, transportation, education, medical and other units.
It's all ordinary people who want to collect. You can't upload people's fingerprints to the fingerprint database of ex-offenders. And there are so many trace experts, at most two or three in a county bureau, and they will be compared one by one until when.
Zhang Xiang was stumped and didn't know how to speak.
How could Director Han not know what he was worried about. He said casually: "This is a lot of work, but we now have some advantages, and we can use stupid methods or modern means." The stupid way is to ask the leaders of the hall to come forward, and they will ask the leaders of the observation group, including Director Zhao, to help. Tens of thousands of fingerprints, numbered and broken down, how many are saved. How many pieces are in a city bureau, it can be compared in two days at most.
It's much simpler to use modern means, but it costs some money to find the company that made the fingerprint comparison system for the Criminal Investigation Bureau to tailor a small system, input all the fingerprints collected, and let Tai Chao's kid tap the keyboard a few times, and it will be done in half a day at most. We will keep citizens' personal information strictly confidential and delete it immediately after they are finished. The equipment and system are kept, and maybe they will come in handy next time. β
Theoretically, as long as the suspect is a local, or one of them is a local, then he will definitely not be able to run away from it.
The question is that this is only theoretical, what if the suspect has only been in the local area and can speak a few words of the local dialect with a local accent? What if the suspect is from a neighboring county with a similar accent, is it necessary to expand the scope of the supplementary recording from one town to one county, and then from one county to one city?
Moreover, there is such a large turnover of people now, many people go to school, serve in the army or work outside, and it is impossible for people to come back for the fingerprint recollection.
To Zhao Zhenxing's surprise, Peng Xiangyuan agreed without hesitation after receiving the call in the middle of the night. It was said that early tomorrow morning, the Department of Equipment and Finance Department would contact a high-tech company that made a fingerprint comparison system, and the money would be paid out of the hall, and the hardware facilities for the "801" in the calculation hall would be provided.
On the way back to the police station, Zhao Zhenxing sighed with emotion: "Director Han, Director Peng trusts you enough." β
"I can't talk about trust, I should have more confidence in our '801', and this system is really useful. We can use it, and the Criminal Investigation Bureau can use it too, maybe more than we do. β
Seeing a few people in suits and leather shoes coming towards him, Director Han Da added meaningfully: "In addition, every time you touch the row in a large area, you can catch a few unlucky eggs." If the county bureau is smart enough, it can take this opportunity to beat the rabbit and compare the fingerprints collected at the scene of the small case by the way, which will definitely be more or less rewarding. β
Fingerprint comparison is one of the main means for the public security department to solve cases, and judicial departments around the world regard fingerprints as the "first physical evidence".
In 2009, the Ministry of Public Security issued a batch of key fingerprints that had accumulated over the years, and in that large-scale comparison operation, a trace identification expert had solved four murders and two serious robberies within a month.
Especially for small cases that are not worth much, there is not so much money to investigate. In the end, it all relied on fingerprint comparison, either it was not broken, and a series of it could be broken once it was broken.
Zhao Zhenxing was convinced of this, and couldn't help sighing: "Director Han, I ran away with you for a day, and I found that what Director Cao said was very reasonable. The backlog of cases is not an immediate homicide case, and if you want to solve the backlog of cases, you have to take some extraordinary measures. β
Director Han Da was happy, and laughed self-deprecatingly: "To put it bluntly, it is to do everything. Director Zhao, do you know what the grassroots criminal police said when we first started to check the backlog of cases, they summed it up, the reason why we can break it, but they can't solve it, is entirely because we have more power than them, and second, they have more money. β
Zhao Zhenxing smiled dumbly and said: "They obviously only see the phenomenon but not the essence, your Jiang Provincial Public Security Department implements the integration of provincial, municipal and county responsibilities, the criminal investigation captain or deputy chief supervises, and the city and county public security bureau leaders must personally intervene, is it true that the criminal investigation team and the city and county public security bureau directors have no power and no money?"
Not to mention that Jiang Province has such a developed economy and abundant funds for handling cases. As far as our backward provinces in the northwest are concerned, they are also willing to invest in the investigation of homicides, and there were two cases that cost millions of dollars last year, and on average, the funds required for each homicide case are not less than 400,000 yuan, and the key is to dare to think and dare to investigate, even Comrade Xiao Jiang can think of leaving home before the investigation of the case, which shows how big the gap between our criminal investigation corps and your '801' is. β
"I can't say the same, there is a saying that the authorities are confused, and the bystanders are clear, our thinking on handling cases is different from that of the task force, and all our assumptions and judgments are based on the work of the task force, and it can be said that what they have done before is very meaningful."
When the leaders of the county party committee arrived, Teng Yaozhou hurriedly stepped forward and introduced: "Director Zhao, Director Han, this is Secretary Lu of our county party committee, and this is Secretary Zhou of our county political and legal committee. β
This is the last item on the second round of the backlog inventory, and it is not the last one to guide the inventory on this trip.
There are still twelve places that I haven't go, get in the car and sleep, just arrive at the place at dawn, just start work, otherwise I won't be able to come home before 8 o'clock tomorrow night.
"Onion Baby" was waiting at home, Director Han didn't have time to be polite to them, so he simply exchanged pleasantries, declined their kindness, and threw Zhang Xiang and Jiang on the road again, and rushed to the next stop overnight. (To be continued.) )
