Chapter 563

The urban area of ​​Qingbai City is not small, with a total of five districts widely distributed. The third most important case in the case of the three corpses on the Jingyang Line occurred in Qingbai City.

Therefore, Qingbai City and the Provincial Department went to war.Because according to the research and judgment of experts, the murderer must be very familiar with the railway lines and railway timetables, and at the same time, he should also be familiar with the local conditions.The last point made the experts have great expectations for Qingbai City.

After all, the population of Qingbai City 20 years ago was not large, and it was dominated by state-owned enterprises, factories and mines, with less turnover of people, and a higher probability of finding the murderer.

However, the result was not as expected, and this shelving lasted for more than ten years.Although it was started in the middle, there was no result and it was still shelved.

Half of the police officers who handled the case had already retired.

The highest position left was Zhang Shizhong, captain of the Net Security Brigade of the Qingbai City Criminal Police Detachment.He is also in his 50s, but when it comes to the case of the three dead bodies on the Beijing-Yangyang Line, he still speaks clearly and clearly, and obviously has a deep memory.

A few people simply found a restaurant, and they chatted while eating.

The restaurant is a fresh fish shop, which mainly focuses on river fish, and does not pursue special methods. It is a pot of fresh fish, which is about half a catty, and it is stewed in high soup, which is really fresh and fresh.

The stewed fish is extremely rotten, so be careful when picking it up, as the spines will separate when you put it in a bowl.

Of course, the most delicious thing is the soup, which is so fresh that people can't help but drink it one after another.

The tofu in the soup is even more delicious than the fish, but if you eat a few bites of tofu and then a bite of fish, you will feel that the fish is delicious again.If it is paired with a bowl of soup, it will be delicious in the world.

Jiang Yuan drank a bowl of soup and a mouthful of meat. He was sweating all over, so he asked Zhang Shizhong: "I see that you have taken a lot of footprints around, didn't you find any suitable clues?"

Zhang Shizhong put down the spoon, wiped his mouth, shook his head, and said, "Footprints are collected, and there are only a few people who can be found in the end. Moreover, the collected footprints are far away from the crime scene, and there are no suspects. .”

The crime scene was on a train track, and there was gravel on both sides of the tracks, making it unlikely that footprints would be left.

Jiang Yuan didn't expect this either. After taking two sips of soup, he continued, "Where are the witnesses? Maybe we can find witnesses through the footprints?"

Zhang Shizhong looked at Jiang Yuan strangely, and said: "From the footprints alone, we can't determine the time. The person who left the footprints may have passed by a few hours ago, or it may have passed by dozens of days ago. It is difficult to find." Witnesses."

"What you said, in fact, the freshness of the footprints is unlikely to be dozens of days ago. It rained two days before the incident, and everyone was affected by it. From the specific analysis of the footprints, the Combined with the footprints of the previous day, there are at least ten small parts."

"I don't know about that." Zhang Shizhong shook his head helplessly: "As for the footprints, we actually asked experts to look at them at the beginning, but we always found people first, and then compared the footprints."

"Well, the current technology is better than before." Jiang Yuan nodded.Needless to say, technology has always been moving forward. Although in the past few decades, many technical masters have emerged in domestic footprint identification, the 53-year-old sheep-herding old man has become the top in the country with his "footprint tracking" technology. The criminal investigation expert known as "God's Eye".

But later generations are doing research on the shoulders of predecessors. After half a century of development, the overall level of identification has been improved a lot, and some experience and skills that predecessors did not have have been summed up.

And this series of skills, the last 20 years, is the outbreak period.

When the case of the three corpses appeared, footprint identification was relatively common, and it was not a big problem to judge age, gender, height and so on.

But in terms of use, finding people through footprints is not mainstream.The main thing is to find people, verify through footprints, and rely more on shoe prints than footprints.

In fact, this is also related to the times. People around 00 would not have a cabinet of shoes at home.Normal people can only wear one or two pairs of shoes. When the seasons change, they don't change their shoes very much.On the other hand, shoes will not be easily discarded until they are worn out. Shoe repairers are ubiquitous in the streets and alleys, and everything from soles to uppers to uppers can be repaired.

Therefore, even if the suspect throws away the shoes, there will always be someone who will put the shoes away, from the rag pickers to the waste collectors to the trash collectors to the trash pickers.

This is the basis for comparing suspects through shoe prints.

Nowadays, such opportunities are becoming less and less. Ordinary people change their shoes every now and then, and those who sell second-hand shoes and throw them into the trash can may not be picked up by others...

From shoe print identification to footprint identification, it is another level of difficulty, and it also requires continuous summing up of experience by later generations.In an academic sense, the regression formula must at least be written.

In fact, in the past 20 years, all kinds of scientific and technological achievements have exploded. Although there are broken articles about defrauding funds with words, there are also some people who have made real achievements.In the field of footprint identification alone, there are many awards for scientific and technological progress.

Of course, it is unavoidable that some people do not trust the Science and Technology Progress Award. In this regard, scientists in the field of basic science may not be able to argue, but technicians in the field of criminal investigation want to prove themselves. It is very simple. Brothers who do not believe, find an important Pick a special place to urinate, and leave a pee footprint by the way, and look back a few days to catch yourself.

Zhang Shizhong only had a rough idea about footprint identification, and he didn't know where the limit was, nor did he know the level of experts.

However, seeing Jiang Yuan's confident expression, Zhang Shizhong said: "If you can catch the murderer through footprints, then there must be no problem..."

"It's not that far yet." Jiang Yuan coughed twice, emphasizing: "The footprints at the scene are far away from the murder scene. It's impossible to say who left them, and there's no way to prove that they were left by the murderer. Let's start with the search Witnesses begin."

"It's difficult to find people with their footprints, as they were 20 years ago." Zhang Shizhong was a little surprised.

Jiang Yuan gave an "en" and said, "In terms of difficulty, it's about the same as finding the murderer in ordinary cases."

He used LV5's footprint identification, plus a layer of temporary skills +1 to find the murderer, and then he might need to use LV5's imaging science. To be honest, with this set of skill sets, he can solve a murder case. , it may be easier than killing one now.

However, even with the LV6 footprint identification, it is impossible to directly call out the ID number of the murderer, so there are a lot of resources to cooperate with it, the investigation to be done, the person to be found, and the inquiries to be made , are indispensable.

In other words, Jiang Yuan can reduce the difficulty of finding people from a technical point of view, but still requires a lot of resource support.

As far as the current case is concerned, it may take hundreds to thousands of man-days just to find these passers-by, and the results found may not be useful.

Zhang Shizhong immediately thought of this, and his expression became serious.

In addition, you can brag and paint cakes. The expenses and the resources to be used are real.

dilute……

Huang Qiangmin drank the soup and let out a satisfied sound.

Zhang Shizhong couldn't help looking over, and said helplessly: "Ju Huang, our Qingbai City is not a wealthy city..."

"We came out this time to work for Bai Gan. Not only did Jiang Yuan play the battle, but also Wu Junhao and so many people helped, and we don't want a penny of your salary." Huang Qiangmin said flatly: "As for the funding Expenses, this is mainly determined by the direction of the case, not to waste your funds..."

"Of course, of course." Zhang Shizhong quickly apologized: "That's not what I mean, I mean... Hey, all right, I'll report to the boss, as long as I can solve the case, I can do anything."

Jiang Yuan said warmly: "This case has been separated for too long, and it needs to be reconstructed. No matter from which angle it is carried out, there are always several steps. It will cost a lot of money and manpower. You have to have expectations."

"I understand. Hey, I understand. Our bureau has actually discussed the matter of funds long ago. However, the difference between paying the money after thinking about it and actually looking at the bill...I understand Long live, understand Long live." Zhang Shizhong He said with a helpless smile.As the saying goes, if you are not in charge of a family, you don't know how expensive it is. Qingbai City Bureau certainly has plans for the case, and the pain is real.

Huang Qiangmin scooped up fish soup for Zhang Shizhong, and when he was overwhelmed with distress, he said: "This case, the provincial department and the ministries and commissions must have support. The railway side is probably willing to give some support. Cui Xiaohu, Cui Department, and Li Chu is helping us run..."

Zhang Shizhong's mood suddenly improved a lot: "It would be best to have support..."

"An interrogation expert from the ministry should come tomorrow." Huang Qiangmin looked at Jiang Yuan: "If someone can be found."

Jiang Yuan nodded and did not say a word. After such a long time, it is easy to identify the footprints, but it is difficult to find someone through the footprints.

Fortunately, there are many factories and mines in Qingbai City. Although there are self-employed people in small markets near the railway line, most of the pedestrians should still belong to the factory and mine workers and their families.In fact, most of the self-employed in the market are family members and relatives of factories and mines. For this part, as long as you work hard to find them, there are always traces to follow.

Furthermore, Jiang Yuan does not seek to find the owners of all the footprints, he just wants to find as many people as possible, add the records of the year, and then decide which direction to advance.

So, on the second day after arriving in Qingbai City, Jiang Yuan's temporary skill +1 was added to... image enhancement LV5.

With the image enhancement of more than 400 minutes, Jiang Yuan first processed the pictures of various footprints.

In the office that day, the roar of the computer never stopped.

Zhang Shizhong came and went with several leaders of the Qingbai Municipal Bureau. Hearing that these newly bought high-performance computers shouted louder than the women of Shang K, he couldn't help screaming inwardly.

Machines are used so ruthlessly that when it comes time to employ humans, one does not know what will happen.
