Chapter 501: Re-verification

"Captain Cui, Captain Li, drink a cup of tea first." Huang Qiangmin took the cup from Wang Chuanxing's hand and personally poured water from the electric kettle held by Tang Jia, completing a cup of Deputy Bureau Chief's handmade, New Year limited, pure Chinese style, limited-time return, bud-stamen Longjing tea.

Cui Xiaohu thanked him, his tiger teeth smiling honestly, and said: "You don't have to be busy. We are just small soldiers, accompanying Captain Jiang to complete this footprint identification."

"Where are there small soldiers in the ministry? They are all heavenly soldiers and generals descending to earth." Huang Qiangmin's face piled up with an 88.88-degree smile, not caring at all about his flattery behavior losing face in front of his subordinates.

Huang Qiangmin firmly believed in one point: Dignity is only on the edge of the sword, and truth is only within the range of the cannon!

Do his subordinates look down on him? May I ask if the subordinates on the left look down on him, or if the first half of this subordinate is baring its teeth?

Cui Xiaohu's loyalty, honesty, caution, silence, low-key, young love for learning, not flashy, good at observing, and good student spirit couldn't resist Huang Qiangmin's smile, and he had to be humble: "We are just doing some work of uploading and downloading, serving experts like Captain Jiang Yuan. You really don't have to be polite. We are waiting for a result, and then we will go back to report."

Li Haochen walked even more in the style of a follower, nodding and smiling, saving even the words.

"How many days can you stay here? I'll organize a customized hospitality plan for us." Huang Qiangmin asked.

"Don't entertain, really don't have to. I have to listen to orders all day long now." Cui Xiaohu said, but still confessed the time: "Three or four days should be waitable. Captain Jiang can do it slowly. If there are changes in the middle, notify me at any time."

He took the opportunity to look at Jiang Yuan. As a practical service talent who had served many experts, Cui Xiaohu felt that three or four days should be enough to have a clue.

Huang Qiangmin obtained a time node, feeling that Jiang Yuan should be able to complete it, and his heart was slightly relaxed. Then he changed the subject and smiled: "We have two major features in Ningtai. One is that there are many mountains and big mountains, and the other is that there are many rivers and deep water. The wild game of Sining Mountain... of course, many are not allowed to be eaten now, but there are still some second-generation and third-generation farmed products...

"But what I highly recommend is the fish of Taihe. Taihe is very long. Many counties and districts in Qinghe City have Taihe passing through, but when it comes to producing fish, it can only be our Ningtai piece. The fish in other counties and districts are too small. Only the deep water here in Taihe can raise big fish. And because they are live fish that have traveled thousands of miles, the wild fish caught in Taihe have a particularly good figure. It's not the figure in the gym, but the figure in the fighting arena. It's exceptionally delicious when boiled..."

Gulu...

Jiang Yuan moved his chair and made some sounds.

Huang Qiangmin immediately stopped the popularization of food and looked over, seeing that Jiang Yuan's posture was a bit strange, and asked with concern: "How is it? Is it injured by climbing the sewer?"

"No, I'm looking at my own feet, thinking about something..." Jiang Yuan actually turned on the temporary +1 skill. The large amount of information that suddenly surged in made his state change a bit.

This skill was originally planned to be left for Dazhuang today, but now it can only be used first.

Dazhuang waiting for a day is nothing. If it's lucky, it can eat another LV5 dog meal. But the special task force in the capital, the consumption of a day is definitely not small.

Jiang Yuan, who had just come out of the special task force, thought about the expenses inside, which were still very exaggerated. As the saying goes, when the cannon fires, gold is ten thousand taels. Once there are many people, the expenses are exponential. 100 people's expenses are not 100 times that of 1 person, and if these people move, the expenses will increase even more.

However, what Jiang Yuan really cared about was the difficulty of the bloody footprint.

The bloody footprint is not difficult. On the contrary, Jiang Yuan looked at the bloody footprint provided by Cui Xiaohu and felt that the difficulty value could be considered medium. LV3 footprint identification is more than enough.

Although LV3 footprint identification is very scarce in Shannan Province, it is not rare in the capital region and for the ministry.

China is really full of talent, but that refers to the vast rural and county areas. Even the capital doesn't include Shanghai.

In an era when a top student from Tsinghua or Peking University in a county town would be discussed for several days, the capital region concentrates six-digit graduates from Tsinghua and Peking University.

In such an environment, asking for help from foreign aid for a bloody footprint of LV3 difficulty, and through the ministry, is very unreasonable.

Therefore, there is only one truth—it is not that the difficulty of the footprint is high, but that there is no matching footprint in the library.

This is the experience Jiang Yuan summarized when he did fingerprints.

If the difficulty of comparing a fingerprint is not high, but it has never been compared, then there must be no corresponding fingerprint in the library.

It's like an animal. It looks particularly delicious, smells quite fragrant, and the rumors in the rivers and lakes say that the soup is extremely fresh and braised is extremely tender. At this time, the animal walks in the center of the village, but no one takes action to catch it, indicating that it either has an owner or is a high-level protected animal.

Footprints are the same. The difficulty of comparing half a bloody footprint is not high. It is understandable for the Changyang City Criminal Investigation Detachment to ask for help. There is a certain probability that footprint experts in Shannan Province will be stuck, or there will be deficiencies in efficiency, but how can the ministry?

Their expert library might have LV5 footprint experts who are very busy or not easy to invite, but LV4 footprint experts are definitely available.

LV4 footprint experts doing LV3 footprints is like a mother hitting a child; it's just a question of how to hit.

This wave didn't win, indicating that there is no matching footprint on the hard drive.

Jiang Yuan connected the hard drive, only looked at dozens of footprints, stopped, and then turned on the temporary skill +1.

This confirmed his idea.

"You should have already found someone to look at these footprints before." Jiang Yuan asked Cui Xiaohu directly.

Cui Xiaohu nodded honestly.

"All finished, no match?" Jiang Yuan pointed to the keyboard.

Cui Xiaohu nodded, then shook his head and said: "There are suspected ones, which were later excluded. Inside, there is a separate folder, which contains suspected fingerprints picked out specifically..."

Jiang Yuan then went to the main interface of the hard drive to find it.

The folders in this hard drive are also very many. The footprints of each household are also listed separately. The superior folders are villages and streets, and there are extra units, which are also listed separately.

Jiang Yuan pulled the interface to the bottom before seeing a "Suspected (wtl)" folder.

Jiang Yuan guessed that wtl is the name of the expert.

After hesitating for a while, Jiang Yuan looked at Huang Qiangmin and said: "Technically, in your situation where you have already invited experts, it is not good for me to look at it again..."

If it is a private invitation, it is indeed like this.

Experts compare with experts. In most cases, there will be no grade difference. Famous experts in the province are usually LV3. Once they reach the level of LV4, after doing a series of cases, they will soon receive the attention of the ministry.

Jiang Yuan is actually the same. After doing the 503 armed robbery case and this case, he undoubtedly entered the ministry's line of sight.

Next, if he does well, then after doing it for a period of time, he will probably enter the ministry's expert library, and then he can be given a title like "Special Invited Expert."

In this case, if experts of the same level, if A can't do it, in fact, the probability of B doing it is not very high.

Finding A and then finding B, one is that it is not very meaningful. In addition, if B really invests a lot of time and energy to solve the problem, A and B meeting again will also be slightly awkward.

To solve this problem, it is best to have the order of the superior.

I execute the order, and there is always no problem.

Cui Xiaohu often serves experts from all walks of life, immediately understanding Jiang Yuan's meaning, and said: "This is Director Song's requirement, there is an official letter, let's prioritize the case."

While Jiang Yuan was talking, he looked at several suspected pictures.

He now has a temporary +1 405-minute skill, and footprint identification has exploded to LV6. In just a minute or two, he not only finished reading these suspected photos, but he could also see the reason why this wtl expert identified them as suspected.

This one should be a dual master of trace identification and footprint identification, but the level of footprint identification should be at the high-level LV3. It is estimated that it is an expert found in the early stage of the case. For this half-bloody footprint, he should have considered the changes in the pattern of the shoe sample more.

Jiang Yuan scanned the page twice and said to Cui Xiaohu: "I think there should be no footprints in the hard drive that can match the bloody footprint."

Cui Xiaohu frowned and didn't speak. The footprints in the hard drive had already been compared once. Asking Jiang Yuan again was also with the mentality of treating a dead horse as a living horse doctor.

However, Jiang Yuan made this decision so "arbitrarily," which Cui Xiaohu couldn't understand.

"From the perspective of criminal police practice, the murderer has a great possibility of being in the footprints of the hard drive. After the crime occurred, we blocked the local area at the fastest speed. And, judging from the two previous crimes of the criminal, there is a habit of staying in the local area for a period of time..." Cui Xiaohu described the situation, which was equivalent to expressing opposition.

"Serial robber?" Jiang Yuan asked.

"Yes, this time I missed and killed someone, so I left a footprint in a panic. Because the parties reported the case late in the previous cases, no clues were left."

Jiang Yuan waved his hand and said: "I don't know the specific case, but from the state of the bloody footprint, I think it is unlikely that the previous expert made such a big mistake."

Cui Xiaohu looked at his colleague Li Haochen.

Li Haochen stood out and said: "If this is your final judgment, it is not impossible, but we also hope..."

"It is impossible to let you run for nothing and go back like this." Jiang Yuan interrupted Li Haochen and said: "I will look at the footprints in the hard drive again later, but from the perspective of solving the case, I have a proposal now. You see if it is feasible."

"Please speak." Cui Xiaohu was immediately energetic. He knew that this kind of expert like Jiang Yuan, if he shirked, he would shirk, and there were times when he was performing routine tasks. It couldn't be said that handing things to experts meant that everything was fine. However, if the expert put forward a new point of view, there must be some thinking components.

This is the greatest value of experts.

Jiang Yuan said: "I will re-identify this bloody footprint, re-define its scope, and you will do the investigation again, how about it?"

"Good, good." Cui Xiaohu agreed.

There are only 0 times and countless times for investigation. Doing it a few more times doesn't count as anything. It's like a plane taking off. What's the difference between flying three kilometers or five kilometers more!

Jiang Yuan pulled a notebook and recorded it quickly:

Male.

20-28 years old.

Height 165 to 168 cm.

Weight: 60 to 70 kg.

The body has traces of exercise.

The shoe has an inner height increase, the shoe size is large, which is size 42. The actual shoe size should be 40 to 41.

The scope Jiang Yuan marked this time is very large, not because he is more cautious, but because the judgment of half a foot is indeed more difficult. Fortunately, it is a bloody footprint. If it were a flat footprint taken by the electrostatic adsorption method, the marked scope would have to be increased.

Despite this, Cui Xiaohu still frowned for a while, and took out a notebook with his colleague Li Haochen to check.

"Captain Jiang, the scope you gave is smaller than the scope we investigated." Cui Xiaohu said in a dilemma.

A smaller scope than the investigation means that the people Jiang Yuan hopes to investigate should have been investigated.

"Hard work to investigate again." Jiang Yuan has done quite a few cases, and he has some understanding of investigation.

He looked at the conditions he wrote again, then drew a circle around the two words "height," and then marked two words below: naked height, and drew three lines to show the focus.

Jiang Yuan tore off this page and said: "I suggest you re-verify carefully within this scope. Because it is not uncommon for people to escape investigation for various reasons. Since the investigation interval I drew is smaller, I hope to check it more carefully."

The criminal police team of a certain branch in the capital is responsible for the investigation, not the ministry. Cui Xiaohu took the paper given by Jiang Yuan and nodded, saying: "I understand, I will report it now."
