Soon, Mr. Gongsun finally confirmed that the flat drum was indeed made of human skin. How is it verified? In ancient times, there were no advanced instruments, and there were no DNA tests.

"Sir, how did you find out?"

After asking this sentence, it attracted the white eyes of Mr. Gongsun, "Won't you make a piece of skin cooked and processed, and compare it?" ”

"Oh, that's not right." Xiao Yu'er retorted: "Mr. Gongsun, if it's really human skin, but this drum noodle is too thick, right?" ”

Mr. Gongsun said: "That's because this flat drum has two layers, and the top layer is the human skin. Moreover, it is glued to the surface of the cowhide by an extremely complex means. The average thickness of this human skin is no more than 3 mm, and it happens to be the flat epithelium of the epidermal layer of the skin, which is very firmly glued to the drum cowhide, and it is impossible to distinguish it unless you are not careful. The process of making this drum is extremely complicated, and the gum used is also very special, as for what? It is not known how many students are sparse and shallow. ”

After reaching this conclusion, Master Bao nodded. Although there is an objective identification by Fubo, it is still not fundamentally determined to be the skin of Huang Lei.

Xiao Yu'er also doesn't believe that this is the skin of Huang Lei, after all, this era is very different and science is underdeveloped. If it is in modern times, DNA paternity testing technology can be used to take the DNA of Huang Lei's immediate relatives for individual identification. The validity of determining biological blood relationship (i.e., the probability of paternity) is greater than 99.999%. However, it is difficult to determine sibling relationship in this way, and at most it can be determined that they are members of the same family, and it is not possible to determine whether they are children of the same parents. It is relatively easy to identify between males because the Y chromosome in their genes is recognizable from generation to generation, while females do not have such a unique marker. But this is all in vain in ancient times.

However, Mr. Bao still has a trick, combined with the original file of the suspect back then, and inquired about the household registration of the guò population. I learned that Huang Lei also has a twin brother named Huang Guang, who used to be an old bricklayer, but now he is old and rests at home.

"Little Fish"

"In"

"You go."

"Slag"

Xiao Yu'er and Mr. Gongsun immediately found Huang Guang and took a certain amount of blood samples from him in the name of cooperating with the case.

Xiao Yu'er asked, "Sir, why do you want his blood?" ”

Mr. Gongsun said: "I have heard that parents and children are dripping blood into the bones to recognize their relatives. "It's about a person who doesn't know who his parents are? Drip your own blood into your bones. If it is biological, then the blood will melt into the bones, and vice versa. Mr. Gongsun was thinking of this method to drip blood into the skin of the man.

Because Huang Guang and Huang Lei are twins, the DNA of the two is the same. So this blood is really absorbed by the human skin, so this drum-faced human skin must be Huang Lei.

Later, after a cooked leather processing, it was said that if a skin can achieve this kind of process, it will inevitably take a long time, about 20 years. Although the master of the zuò leather did not know about human skin, the cowhide, wood, copper hoop rings and piled up relics used in the drum body also have the same time attributes, indicating that the whole flat drum was made synchronously, and the human skin was not sticky in the later period.

In this way, it is proved from two aspects. This human skin drum was made 20 years ago. Combined with the fact that Huang Lei was found burned to death in the Qinglou fire in Guangzhou, it shows that the time of making the human skin drum should be the year after his death, or within five years.

However, because the physical evidence examination can only give a broad time period. Therefore, whether Huang Lei was really burned to death in the fire has become a temporary unexplained doubt.

However, at that time, it was more inclined to be made at the beginning of the third year of the Northern Song Dynasty, because it was unthinkable that Huang Lei had fled for five years. His skin would be cut off to make a drum and sent back to the Duanzhou Opera Troupe.

Combined with the only clues currently in hand, the task force decided to start with the source of this drum. Xiao Yu'er immediately went to the troupe and found the old grandson who was watching the warehouse to understand the situation.

According to Lao Sun Tou himself. His real name is Sun Baoku, 54 years old, and he has been working here since the fourth year of Tianxi to work as a watchman and a storehouse.

Lao Sun Tou took out the spare parts register and looked for it for a long time, and then told us that this drum was there before he took over in the first year of Tiansheng (that is, Song Renzong's accession to the throne), and as for the specific time, it is impossible to verify.

Xiao Yu'er asked him if he still had some impressions of who always likes to use this drum. Lao Sun Tou said that he didn't know, now that the troupe is in a recession, all those who have the ability are gone, even if they encounter a performance, they are who copy and use it, anyway, just those guys.

After this external transfer, Xiao Yuer came back to report.

Xiao Yu'er said: "According to Fubo's discovery and the identification of the physical evidence found, the drum-faced human skin has been determined to be the skin of Huang Lei's back. In addition, Huang Lei fled to Guangzhou that year, and many local eyewitnesses confirmed it. Therefore, assuming that Huang Lei was skinned and made into a drum 20 years ago, let's not talk about whether Huang Lei was burned to death in the fire of the Qinglou, just talking about this drum, why did it appear in the troupe of our city? There are two possibilities:

First, Huang Lei had obvious tattoos on his back, and in order to prevent being recognized in the future and evading sanctions, he found someone to skin him alive before fleeing to Guangzhou. And this skin with an eagle-shaped tattoo was later made into this drum, which flowed into the troupe. Who is this drum maker? He shouldn't be Huang Lei himself, then he can only be the one who practices skinning. At the same time, it could also be the one who knocked Faber unconscious that night.

Second, after Huang Lei fled to Guangzhou, he had a grudge with others for various reasons and was killed, and the murderer skinned him and made drums, and then sent him back to our city. In this way, the identity of the murderer is worth scrutinizing. If he was a local in Guangzhou, why did he come to Duanzhou? Is it just to send a drum? This obviously doesn't make sense. It can only be a local, most likely who fled to Guangzhou with Huang Lei, and he may still be the one who knocked Fu Bo unconscious that night. Perhaps there was a conflict between the two after they arrived in Guangzhou, and this man made this drum from his human skin after killing Huang Lei, and then sneaked back to the troupe with the drum. ”

Master Bao thought carefully about the two ideas that Xiao Yu'er had speculated about, and nodded in agreement. At the moment, these are both possibilities.

"Very good." Master Bao cast an encouraging look, and Xiao Yu'er was complacent when he heard it.

Said: "The analysis is very reasonable, but it is still in the speculation stage as to whether the murderer is from Duanzhou or Guangzhou, but for this kind of skinning behavior, Master Ben tends to do it locally in Guangzhou." If Huang Lei was skinned locally, he would have to recuperate for at least a long time, and with the attitude of the yamen at that time, since he had escaped capture, the first thing he had to do was to leave the city quickly, and it was too unwise to risk being stranded. ”

Hearing this, everyone nodded unconsciously, it is true. Others also expressed their own speculations, and they generally held similar views to Xiao Yu'er just now.

After listening to everyone's analysis, Master Bao nodded and said, "There are two other points I need to remind you of, first, Fu Bo only saw a charred corpse back then, and there was not enough evidence to prove that that person must be Huang Lei. Therefore, Huang Lei's life and death are still in doubt, and perhaps he still lives somewhere with the scars on his back that we don't know. Assuming that Huang Lei is not dead, how can the body that appeared at the scene of the fire be explained, who is he? ”

He glanced at the crowd, and this should indeed be considered. Master Bao continued: "Second, where the murderer is from, what is the relationship with Huang Lei, and the time when the drum was made can all be determined through careful investigation. However, after so much time, the case still happened in a different place, and it is extremely difficult to investigate, so you must pay attention to the murderer's psychogenic motives, that is, why did the murderer have to peel Huang Lei into a drum. At the same time, putting aside the accidental factor of its flow into the troupe, why did the murderer send the drum to the Duanzhou troupe? Does this mean that the eagle-shaped tattoo behind Huang Lei has a special meaning for him, and must be sent to the troupe in the form of an adult leather drum in order to satisfy his inner secret needs? ”

After analysis and research, it was finally unanimously decided that since the human skin drum was found in the Duanzhou opera troupe, the person who rescued Huang Lei or the murderer, whether he was from Duanzhou or Guangzhou, could have been a member of the troupe at that time, or had a close connection with it, otherwise, he would not have sent this drum to the troupe for no reason after killing people and skinning them.
