Situ Ce nodded, took the iron stick from Helanbing's hand, pointed to the clean end on it, and said, "You said, why is there no blood in this section?"

He Lanbing observed carefully for a while and said, "The blood stain is completely gone when it comes here. From this we can see that the iron rod should be wrapped with cloth or something. After the beating, the murderer took off the wrapping on the iron rod, so the iron rod is not covered with blood stain."

Situ Ce said: "The murderer may have had gloves too! However, I searched the whole house and found no cloth, gloves or anything else wrapped in iron rods. Therefore, the murderer may have taken the package away."

He thought to himself that there was no fingerprint on one end of the iron rod. This must be because of the friction when waving, the iron rod's original old fingerprint was wiped off, so he did not find a single fingerprint.

Does the murderer have anti-investigation measures to wear gloves to prevent fingerprints from leaving? Logically speaking, only people in modern society can have such knowledge. In ancient times, there was no knowledge of fingerprint identity, and there were never any cases that proved that the ancients used fingerprints to solve cases, so it was almost impossible to have such knowledge.

Then why does the murderer have to wrap iron rods or gloves with something? The weather is still very hot now, so it is impossible to wear gloves to prevent cold. If the iron rods are wrapped with cloth, this can explain the problem of wrapping iron rods, but it cannot explain the problem of why the murderer took away the package afterwards.

He pondered and wondered why this happened, but Helanbing thought about how to find the package. Since there was no in the house, would it be...? Helanbing immediately walked to the door, called Brother Sun over, and told him and a few constables to search the entire yard to see if there were no suspicious objects, such as blood-stained cloth or something.

Brother Sun and others started searching, and He Lanbing returned to the house and asked Situ Ce: "Is there any other clues that need to be found?"

Situ Ce squatted down, pointed to the bloody footprints on the ground, and said, "The shoe prints here are three other footprints, except for the deceased's own, one of which is the one from Gao, the deceased's husband's family. I have compared the shoes she replaced, and the pattern on the soles matches the ones on it. It proves that it is left by this pair of shoes. However, whether it is Gao's, we cannot just have the final say, we must check..."

"I'll use these shoes to compare with her other shoes!"

"Yes!" Situ Ce pointed to several other shoe prints and said, "These shoe prints belong to two people, because the soles are different, one is diamond-shaped and the other is half-moon-shaped. It is proved to be different shoes for two people. Moreover, from the size of the shoes, one pair is obviously smaller. The shoes of this size are probably women's, and the other pair is likely to be men's. Of course, it is not ruled out that they are tall and big-footed women like Gao."

"Will it be three people doing it?"

"It is possible, but only one weapon was found, and there was only one type of injury on the deceased's head. Therefore, if the other two were also accomplices, they might not directly carry out the injury, but instead stand up to cheer or help subdue the deceased."

"Yes!" He Lanbing looked down for a while and said, "This pattern has some characteristics. How to take it off? I went to the shoe and sock shop to ask if I could find some clues."

Situ Ce said: "The blood on these blood footprints is very sticky. Although it has dried now, it has not been completely dry yet. Spray a little water mist on it and then rubbing it with rice paper. It should be able to be taken down directly."

"Okay, I'll find paper!" He Lanbing ordered the detective to buy a piece of rice paper, then brought a bowl of water, and gently sprayed it on the footprints. Then spread the rice paper on it and pressed it gently. The bloody ground was easily stained with blood marks. After taking it down, a complete shoe print was taken off. The pattern on it was very clear.

They laid down all the clear footprints on the ground one by one, took them out, called Tang Tang, and asked her to go to the shoe and sock shops in the city to see if there were any clues.

At this time, Brother Sun and others, who were responsible for searching the entire house, came back and reported that they had not found any suspicious things, and of course they had not found any blood-stained cloth. The two of them judged that the murderer must have taken away the cloth wrapped in the iron rod.

Now, the most important clue fell on the blue handkerchief on the deceased's face, and Situ Ce hoped that he could extract the fingerprint from it.

How to make the sweat-submerged fingerprints appear on textiles? This is a relatively difficult problem in criminal investigation. Because the surface of the textile is porous and has strong permeability, it is impossible to use fingerprint brushes to directly brush. Also, because the textile pattern is relatively complex and the background fluorescence itself is relatively strong, it is often easy to cover the fingerprint fluorescence, so the method of using a laser device to illuminate and display is not ideal.

Situ Ce thought for a long time and finally decided to use a combination of physics and chemistry to find the fingerprints above, that is, first use 502 rhodamine 6g to process the fingerprint, then use a laser emitting device to illuminate and finally take a photo with a camera. This is because, after using 502 smoke-making method, the white polymer on the fingerprint lines will be much more than textiles, and the rhodamine 6g is a strong fluorescent substance and is brown-red. In this way, the blue-green laser can be used to stimulate and produce fluorescence. Then take a photo with the camera.

This idea is very correct. He finally found a clear fingerprint among the many blurred marks mixed on this blue cloth!

Situ Ce was very excited. He returned to the Mi Er family where the incident occurred, found Gao, and extracted her ten-finger fingerprint. Gao was naturally unhappy, but she had to follow the request from the yamen.

Situ Ce took the fingerprint back to the inner house of the yamen and compared it with the displayed fingerprint. As a result, it proved that the fingerprint on it was not Gao's, which confirmed what Gao said.

Next is waiting and waiting for the results of the investigation.

The first report was the result of the shoe printing investigation. Although there are many shoe sock shops in Zhenhai County, they can see the patterns very quickly. The master embroidered girls of these shoe shops are clear about the patterns of the soles they made, and they can tell whether they are their own works at a glance. So they quickly checked. Both shoes were not sewn by any shoe shop. In other words, the shoes printed by these two shoe printings are probably taken care of by their own homes. That is to say, most of the ancient women were skillful, and all kinds of female reds were handled by themselves. Moreover, each of them had their own abilities. The patterns and patterns may be the same, but the stitches were delicate and the sewing methods were different. There were so many big girls and wives in Zhenhai County. If they wanted to find out which insole was made by the insole, they were really looking for a needle in a haystack.

Now, the only thing that can be hoped is the only brothel woman who has visited. And this clue is what Situ Ce and the others have the most hope.
