Jiang Tian pretended not to hear and continued: "Brother Shen, but I'm not afraid of these dead people, because they are nothing more than a cold body to me. What I'm afraid of is the moment I see them dying, and I'm afraid that I'm going to experience that pain. But I am convinced of what my father said about seeing fate in me, because although I am afraid, I want to give justice to the deceased. ”

Jiang Tian patted Li Yu's shoulder, "Haha, let's work, uncle." ”

Li Yu glanced at Jiang Tian deeply, and only then did he look at Jiang Tian properly.

"I saw that today's newspaper says 'Madness Reappears', what does this 'Reappearance' mean?" Jiang Tian asked, looking at the photo of the corpse.

"Three years ago, there was a serial murder case in H City, and the deceased were all young women, all of whom died of excessive blood loss from skin on their backs. At the time, I was in charge of the case. Because the modus operandi was the same, we did a joint case. After investigation, the location where the body was found was not the scene of the first crime, there were few clues left, and there was no surveillance near the place where the body was dumped, so we walked into a dead end. ”

Later, the murderer committed the crime again, but this time it was very strange, after the murderer killed someone in the hotel, he did not choose to throw the body, and was even photographed by the surveillance when he fled the scene in a hurry! It's incredible! The first few times we committed crimes, we didn't even find the scene of the first crime, but this time we even took a picture of our face, and I wondered if it was him. ”

"But we opened an investigation into the suspect anyway. We found out that this person's name is Li Mi, 42 years old, a native of H City, living in District G, single and unmarried, and currently living alone. Although there are still many suspicions, considering Li Mi's appearance at the scene of the murder, we still decided to start arresting after we have all the information about the suspects. On the day of the arrest, Li Mi's neighbors told us that Li Mi had not come out since he entered the house at noon, and that he would not come out after I called him many times outside Li Mi's house, so Chen Qi and another policeman, Chen Qi, prepared to enter by force. ”

"But what I didn't expect was that Li Mi actually had a gun! At that time, he was hiding on the side of the door, and Xiao Chen didn't pay attention after entering, and was shot by Li Mi. I reacted immediately and fired a few shots at Li Mi, who also jumped into a hole and fled. I was shot three times and survived, but Xiao Chen died. Speaking of this, Li Yu's voice was a little choked.

Shen Sen patted him on the shoulder to show comfort, and then said: "In this case, it is also possible that Li Mi did it back then." ”

"There's a possibility, this crumb may be back." Li Yu gritted his teeth and said.

"Motivation." Jiang Tian looked at the photos at the scene and said, "I just looked at the news reports and case files of the Li Mi skinning case, and found that there is a problem that seems to have never been clarified, that is, why did this Li Mi kill people back then?" And why do you want to come back and kill people now? ”

Shen Sen and Li Yu also began to think about this question.

"And, in the last case, why did Li Mi go against the norm and make a case that should have been leakless full of loopholes, so casually leaving fatal evidence?" Jiang Tian continued.

"By the way, when it comes to motives, there is no mention of them in the reports and dossiers, which means that it has been three years, and you have not even figured out the most basic motives." Jiang Tian put the file in his hand on the table in front of Li Yu. Although the tone was light and light, it could be heard that Jiang Tian was already a little angry.

A trace of shame appeared on Li Yu's face.

"What I wanted to say just now was the first and second points, and the third point."

Shen Sen and Li Yu both looked at Jiang Tian solemnly. Especially Li Yu, his eyes have completely lost the disdain just now.

"Third, I speculate that although the modus operandi of the skinning case three years ago and the current skinning case are similar, they are not committed by the same murderer!"

"Why?" Shen Sen and Li Yu asked in unison.

"Look." Jiang Tian put the photos in his hand on the table one by one, "The skin that the deceased was stripped off was very regular, all of them were the upper part of the back, and they were all about 20cm × 30cm in size, which was very regular. But the body found yesterday was different, the skinned area was large and irregular. ”

"That's true." Shen Sen looked at it carefully for a while and said.

"The above is just the first suspicion that makes me suspect that the murderer is not the same person, and the second suspicion is a small detail." Jiang Tian put a photo on the table, "Look at the third deceased that year, there are still half tattoos left on her back skin. Judging by the photos taken by the deceased in a backless outfit before his death, it was a butterfly tattoo. On the stripped skin is the other half of the butterfly tattoo. The deceased found yesterday has a dossier that his family said that there was also a butterfly tattoo on the skin that had been peeled off, and the shape of the skin was also very similar to a butterfly, and I think the murderer skinned it according to the shape of the butterfly. ”

"Kind of makes sense." Li Yu stared at the photos with his chin propped up.

"So I feel that the murderer back then seemed to want human skin, and the murderer now seems to want that tattoo even more!" Jiang Tian said.

……

Jianqiang tattoo parlor.

The owner, Xu Jianqiang, is giving a female customer's back tattoo of a rose, which is almost finished.

At this time, the door of the store was pushed open, and a tall and thin young man came in from outside, it was Xu Jianqiang's son, Xu Jiaxin.

Xu Jiaxin stared at the woman's back for a while, then walked to Xu Jianqiang's side, put the buns and soy milk in his hand on the table beside him, and said expressionlessly, "Dad, your breakfast." ”

Xu Jianqiang let out an "oh", did not look up, and continued to focus on the work at hand.

Xu Jiaxin glanced at the tattoo on the female customer's back again, until the female friend who was with the female customer frowned and looked at him, and after pretending to cough a few times, Xu Jiaxin left, walked up to the second floor, and returned to his room.

Xu Jiaxin came to the bed and squatted down, took out a basin from the bottom of the bed, and in the basin was a pair of blood-stained white sneakers. Xu Jiaxin picked up the basin and went into the bathroom, and soon the sound of "whooshing" water came from the bathroom.

……

The next day, the H Municipal Public Security Bureau.

"Scalpel?" Jiang Tian asked.

"Yes, scalpel. Based on the characteristics of the incision, we deduced that the murder weapon was a thin, tough, and very sharp blade, which was confirmed by comparison to be this type 10-27 scalpel blade. A forensic doctor said and handed Jiang Tian a picture of a scalpel blade, "We have studied the knife technique again, and found that the murderer did not cut directly with the blade, but put the blade on the hand-held object to cut." And the murderer used a lot of force, and the knife was not skillful and flexible during the cutting process, so he should have used acupressure to cut the skin with a knife. This method of using a knife is often used for skin tissues that are difficult to cut, and it is obviously not necessary to use this method of knife to peel off the skin on the back. It can be seen that the murderer has some experience in using scalpels, but he is not proficient in it, and he should have just started to operate with scalpels. ”

"Coupled with the fact that the deceased was anesthetized with ether before his death, is it possible that he was the kind of intern doctor in the operating room?" Li Yu muttered to himself.

"Officer Li, what kind of murder weapon did the murderer in the skinning case three years ago use?" Jiang Tian asked.

"Dagger."

"That's weird, then." Jiang Tian fell into deep thought.
