Chapter 471 Don't Brag

Captain Bai was a little guilty at Huang Qiangmin's words, he laughed loudly, and said: "You can solve the case, you can say anything, if you can't solve the case, don't brag about it."

Huang Qiangmin crushed the Huazi in his hand to death in Diaolan's arms, lit another one, and said with blurred eyes: "Old Bai, I didn't have much contact with you before, and I didn't realize that your mouth is real. It's hard."

"You win, you can say whatever you want. If you can't solve the case, get out of here." Captain Bai's eyes became extraordinarily arrogant, and although he could see through the straightforward aggressive method at a glance, he was still very upset.

Huang Qiangmin laughed: "If your IQ is stronger, you should know that the reason why we, Jiang Yuan, came to your Shiting County is because we have continuously solved backlogged cases... The number of murder cases you have solved in your life, Bai Jian, surpasses that of ours. Has Jiang Yuan broken a lot in two years?"

Captain Bai did not lose the battle, and said without hesitation: "No need to compare, the number of murders I have solved in my life may not be as many as your Jiang Yuan solved in a year...but..."

Huang Qiangmin's expression softened at first, but when he heard the word but, he could only look helplessly at Captain Bai Jianbai.

Bai Jian said: "Even if you have solved many cases and solved countless cases, it doesn't mean that you can solve this case. Let me just say that, no one in the world dares to say that he can give all the cases to you." It's broken, don't you think?"

Huang Qiangmin was stunned when he heard that, he didn't even have the confidence to crush such a hard mouth just by throwing it at him.

Liu Jinghui was amused by the observation, and said with a smile: "Bai Da, logically speaking, what you said just now is a sneaky change of concept."

Jiang Yuan wrote down the number in his notebook, and said: "The murderer probably stepped on blood. In order to avoid leaving too obvious marks, the murderer took off his shoes here and put on a pair of the victim's shoes."

Changing shoes in the middle of a crime has been heard of, but rarely seen.

"Did you track down the footprints on the window?" Jiang Yuan took out a photo, which was a close-up of one-fifth of the footprints.It was almost the middle part of a shoe, which was left by stepping on the window frame.

The entire crime scene was in a mess, and it was impossible to tell which footprints belonged to the villagers, which footprints belonged to the murderer, and which footprints belonged to the policemen and joint defense members of the later police station. Only one-fifth of the footprints on the window were basically Definitely the murderer.

Jiang Yuan quickly made a summary and looked at Captain Bai.

"The heights of the two are similar, but there is not a small difference in weight and age. Therefore, from here, we can tell that some of the old cotton shoes' shoe prints belong to the victim Ma Jun, and others are probably the murderer's."

The yard of Ma’s house is hard ground. From the hard ground to the tiles in the living room, a lot of footprints are left, but the clarity is not high.

Bai Jian had no way to refute, and even felt that what Jiang Yuan said made sense.

Immediately afterwards, Jiang Yuan released a few more blood-stained photos, saying:

Unless it's LV5!

"The murderer wore his own sneakers to enter the room first, but not long after entering, he met the victim Ma Jun. Ma Jun probably didn't realize that someone had entered the room. The murderer killed the victim Ma Jun very quickly. Afterwards, he After taking off his own shoes, he took out a pair of Ma Jun’s shoes from the shoe cabinet not far away, continued to attack, and finally took his own shoes and left.”

Captain Bai was embarrassed to argue with Liu Jinghui from the provincial department, so he raised his mouth to support himself.

From the one-fifth footprint of the window frame to the sneaker on the ground, it is no exaggeration to say that even if you don’t have the footprint identification skill of LV5, you must at least get the high-level LV3. Some trail experts are beyond reach.

"The shoe sizes of the victim Ma Jun and the murderer are about the same size. There should be only half a size difference, the difference between 42 and 42.5."

For a homicide backlog, any new clues are invaluable.What's more, the clues in front of him sounded reliable.

In contrast, everyone pays more attention to the more curious shoe change, but it is 1-2, which can be easily judged with a low-level LV3.

This is a typical location of burglary footprints. The trace inspection in Shiting County also tried their best to take a relatively complete footprint.
However, due to the problem of the construction of the window frame, it is small in itself, and it did not play a role in the end.

It is also impossible for Jiang Yuan to tell Muggles about "the influence of different tones on the power of magic". After waiting for a while, he continued: "The key is that the same shoe print can show two physical characteristics, which also shows that this pair of shoes Two people walked through the..."

Bai Jian opened his eyes wide, feeling that he could see it, but also felt that he didn't see anything.

Jiang Yuan took a third photo, which was a mass of smeared blood, number 277.

And this step is the most important 0-1.

Bai Jian knew what Jiang Yuan was asking as soon as he heard it, and said: "We asked someone to look at this footprint at the beginning, it is too small, and there is no way to use it as evidence."

Huang Qiangmin also snorted pretending to be calm, and was also curious inside.To be honest, he has not seen many difficult cases. He may have watched half of the difficult cases in his life with Jiang Yuan.There is no way, the murderer who does this kind of case, he can't go to Ningtai County to commit crimes, and only Jiang Yuan, a policeman who commits crimes on the go, can be well-informed.

Previously, Bai Jian and other criminal policemen in Shiting County had considered taking the case from the direction of the footprints, but there were too few clues and too many footprints.

At this time, Bai Jian quickly said: "This kind of old cotton shoes were sold a lot back then, and there are many people in Majiazhuang who wear the same soles, how can you tell them apart?"

Bai Jian was taken aback for a moment, and his expression gradually changed to: Are you kidding me?
Because in the two photos in front of me, the former is the footprint of sports shoes, and the latter is the footprint of old cotton shoes.

"The same pair of old cotton shoes have discordant footprints. Although it may be worn by family members, but compared with sports shoes, they can still be distinguished."

Jiang Yuan had looked at the footprint carefully just now, so he picked up another photo from his hand, put it in a row with the one-fifth footprint, and said: "These two footprints are together. They belong to the same person footprint."

However, Jiang Yuan didn't have to work so hard now, the newly raised LV5's footprint identification just came into play when encountering such difficult footprints.

Jiang Yuan said relaxedly: "Even if the same batch of shoes leaves the factory, the soles are the same, but the degree of wear is different. The worn soles are naturally different."

Similar to fingerprints, footprints also need to have a certain size and certain feature points for comparison.

At this time, Bai Jian's heart was beating violently.

If it is a super-heavy case, there are no clues at all, and when you must rely on footprints, you can pack all the footprints in the yard, classify, and compare them. Then find a high-level LV3 footprint expert, and you can do this case. Just like what Jiang Yuan did before, the whole process is cumbersome and time-consuming.

Jiang Yuan began to post a large number of photos, which were photos of the footprints of old cotton shoes and sneakers indoors.

One-fifth of the footprint is only the middle part of the shoe, which in the eyes of normal footprint experts is basically evidence of abolishment.

The two photos are all footprints, one is only one-fifth of normal, and the other is complete.

"All in all, looking for a breakthrough through the footprints on the spot, at present, I think it is feasible."

Bai Jian said, "That's it. What do you want to ask?"

Now, not only Bai Jian, but everyone else in the office crowded over.

At this time, Jiang Yuan said: "Bai Da, let's find two criminal police from the task force of the Majiazhuang Miemen case, the ones who follow from beginning to end."

The shoes are different, it is said that they are the footprints of the same person...

Jiang Yuan put up three photos on the spot as an example: "These three photos are the crime scene. The footprints of the three pairs of the same old cotton shoes can be seen. The wear spots on the right, left, and heel are different. .”

If Jiang Yuan's point of view is confirmed, there will really be new clues in this case.

Jiang Yuan explained on the spot: "I think it should be that the murderer changed his shoes after completing the crime."

"The murderer should have a certain understanding of Ma Jun's family. You can tell from the movement of the blood stains that the murderer's course of action is very straightforward." Liu Jinghui suddenly said, "From the same village? Or relatives and friends?"

Jiang Yuandao: "It's very simple to kill people."

"Majiazhuang is a relatively remote village. A few years ago, few outsiders would go there. You need to understand the layout of Ma Jun's house, especially if you can find Ma Jun's house, you should be a local. Right. However, Ma Jun’s family is not too rich, and he was the first one to be burglarized after finding his house?” Liu Jinghui thought while talking, and a lot of inspiration burst out in his mind.

Huang Qiangmin silently took out his mobile phone and started sending messages to several leaders in charge of Shiting County.
