Municipal Police Department, Forensic Medical Office.

Chen Mengnan is conducting an autopsy on Li Yue's body.

Lin Yuhan and Wu Hao stood beside her and waited patiently, with the previous experience of the headless female corpse, they were already familiar with it at this time.

There was a strong smell of blood in the room, but Chen Mengnan didn't care about it.

She took out a ruler and carefully measured it, the knife was 13 centimeters deep, almost penetrating the woman's body, and the depth was the same as the length of the blade of the fruit knife, that is, the part above the handle of the knife was completely submerged.

Chen Mengnan carefully observed the wound with a magnifying glass, as if she didn't feel clear enough, she picked up the scalpel from the instrument tray again, and made a straight incision along the woman's collarbone, chest, and down to the lower part of the navel, revealing bloodshot fat and bright red muscles.

The scalpel made a muffled "click, click" sound with her movements, until the woman's internal organs were all exposed.

The entire ribcage was split in half, and Chen Mengran stopped the movement in his hand and said, "The position of the knife is located on the sternal xiphoid process at the bottom of the sternum. ”

"Does it have any special meaning?" Wu Hao asked.

"This ......" Chen Mengnan turned his head to look at Lin Yuhan next to him.

"Let me explain it to you." Lin Yuhan wore gloves and broke the muscles near the chest cavity and said, "The position of the human sternum is in the center of the chest cavity, connecting the left and right ribs. It's shaped like those slices of pork ribs you see in the wet market......"

"Gnea~" Wu Hao glanced at Lin Yuhan fiercely, can he depict it so vividly!

He suddenly remembered that he had eaten braised pork ribs this morning and last night, and he felt a little sick to his stomach at this time.

Will you be able to face the ribs well in the future!

Lin Yuhan ignored him and continued: "The sternum is divided into three parts: the sternal stem, the sternal body, and the xiphoid process. The xiphoid process is at the very bottom of the sternum. Before the age of 30, this part is a piece of cartilage, and after the age of 30, the bone will calcify, increase in density, and harden the bone. The deceased, Li Yue, was thirty-three years old, and the wound was located just on the xiphoid bone, indicating that it required a lot of force to pierce it. Behind the xiphoid process is the pulmonary artery, which directly cuts the artery and kills him on the spot. It can be seen that the murderer was a premeditated and deliberate murder, and he did not give the other party a chance to breathe and call for help at all. I'm still saying that the murderer is very likely to be proficient in human anatomy. ”

"How do you know that Li Yue is thirty-three years old?"

After listening to it for a long time, Wu Hao suddenly asked such a sentence that had nothing to do with the case, and turned his head to look at Lin Yuhan with playful eyes.

"I've investigated her," Lin Yuhan told him truthfully, "so I have an impression." ”

"Ha, I see," Wu Hao continued, "So, you mean that the murderer is likely to be a doctor?" ”

"That's not necessarily, it's just that there is such a possibility," Lin Yuhan stared at the corpse on the table with a solemn expression, "In any case, being able to commit three cases in a row shows that the murderer is experienced and a vicious man, he can be any identity, an identity that is not known to us." ”

"Three?" Wu Hao seemed to smell something, and kept looking at Lin Yuhan with puzzled eyes.

"Uh, ahem, that, two, the mouth is scooped." Lin Yuhan realized that he had slipped his mouth. He subconsciously mixed up the case of Wu Dandan.

However, the police do not know about this case for the time being.

Wu Hao didn't continue to ask, but he still stared at Lin Yuhan with cold eyes, as if he was full of doubts about his words.

Zhao Hong from the Physical Evidence Department walked in, carrying a transparent plastic bag in his hand, and handed a few pages of information to Wu Hao: "Team Wu, the fingerprint test results on the murder weapon have come out, and there are two fingerprints on it, one should be a female fingerprint through shape and amino acid analysis, and the other ......"

"What's wrong?" Seeing that he wanted to speak and stopped, Wu Hao followed and asked.

"The other one I feel very familiar, as if I just saw it a few days ago, so I compared the fingerprints extracted from the photo that Meng Nan gave me a few days ago, and the results matched, this is ...... Chen Yousheng's fingerprint ......"

"Damn!" Wu Hao slammed the materials on the table, and went out to beckon, "Gao Shengli follow me, arrest someone!" ”

"Okay senior brother!" A tall, mighty man stood up from his seat.

"Catch someone!"

Lin Yuhan heard his shout, took a step, and stood in front of everyone.

"What are you doing!" Wu Hao glared angrily, "Don't think that Lao Tzu is used to you just giving you face." If you delay the police handling the case, I can lock you up! Believe it or not, I'm telling you to get out of the police now! ”

Lin Yuhan ignored his domineering appearance and asked, "Do you have evidence?" Why arrest people? ”

"With his fingerprints on the murder weapon! Here's the proof! Wu Hao pushed Lin Yuhan away and walked forward.

"Does having fingerprints mean it must be a murderer?" Lin Yuhan turned his head sideways and turned his back to him and asked coldly.

Wu Hao's footsteps stopped in place, and he heard Lin Yuhan's terrifying voice that almost made him unable to breathe, "Have you forgotten?" The case from 10 years ago also has my fingerprints......"

He turned his head to stare at Lin Yuhan with anger on his face, and said nothing.

What do you mean? Is this a provocation or a show-off?

"Fingerprints can only be used as a reference for the direction of investigation, if Chen Yousheng tells you that someone else stole his knife and then killed his wife, what would you do?" Lin Yuhan asked.

"Or rather, the knife was brought out of the house by her wife."

An annoyed expression crept up on Wu Hao's face: "What does Detective Lin mean, I don't care about such a suspected murderer?" ”

"You must be in charge, and if the chain of evidence is sufficient, you can arrest people!" Lin Yuhan changed his tone, "In the case that the chain of evidence is not sufficient, you had better investigate clearly, visit more, or ask more, so as not to bring unnecessary trouble to your work." Chen Yousheng's lawyer is probably not so easy to mess with, of course, I just advise, this matter has nothing to do with me. ”

Wu Hao stopped talking, and Lin Yuhan continued to add: "Maybe you can visit their neighbors or company employees, ask Li Yue what was abnormal last night, investigate why she appeared in Nanhu Park, and then take the next step." Also, I went to Chen Yousheng's Landi Group to investigate and inquire about Chen Yousheng's recent status, and I noticed that it was an inquiry, not an arrest. ”

"Okay, thank you for the advice."

Wu Hao turned around and walked past Lin Yuhan.

The moment he passed by, he turned his head sideways and whispered, "If I had known that you had done that thing ten years ago, I would have killed you with my own hands." ”

Lin Yuhan's eyes were slightly cold, and he didn't answer.

It wasn't until Wu Hao's figure completely disappeared from his eyes that he turned around and said slowly: "If one day it is found out that I did it, I will help you finish it." ”
