Make matters worse by attempting a coverup.

These four words appeared in Lin Yuhan's mind.

Could it be that because the murder was committed in public, the murderer could not completely dispose of the traces of the crime scene, so he made such an act?

When I think about it, it's a bit unreasonable.

Through many battles, Lin Yuhan can clearly feel that the murderer is a high-IQ criminal with an extremely quick mind and clever design, how could he commit murder in such a hurry, or make such a low-level mistake?

He must have had his own reasons why he had to.

Lin Yuhan checked the traces in the house again. There was blood in the corner of the showcase, blood on the desk, blood on the chair...... The blood stains scattered here and there formed strange scratches on the ground. The contents of the room were thrown into a mess, and many glass and porcelain products were even broken.

"Grandpa, your grandson called you......" the cell phone rang again.

Lin Yuhan picked up the phone: "Hey, Captain Wu, is there something wrong?" ”

"Chen Yousheng has been caught." Wu Hao said, "A major breakthrough has been made in the case. ”

"Did you find anything?" Lin Yuhan asked.

"Of course, the tools of the crime were found in the backpack he was carrying, as well as the victim's head."

"Huh?" Lin Yuhan felt a little strange, and hurriedly asked, "Can I go to the police station to have a look?" ”

"Of course not." Wu Hao replied, "The police station does not allow outsiders to enter casually......

"But......," he continued, "If you have important clues about the case to the police, I can make an exception to meet you......"

"We'll talk about it when we meet." Lin Yuhan hung up the phone directly.

Some people can't get used to him and are easy to go to heaven.

When Lin Yuhan arrived at the Lanhai City Police Station, Wu Hao was "supervising" Chen Mengnan's work in the forensic office.

"Why did Captain Wu come to the forensic doctor's side without interrogating Chen Yousheng in person?" Lin Yuhan walked over and asked.

"Avoid suspicion," Wu Hao replied, "Everyone knows that I have an opinion on Chen Yousheng, and I want to avoid the suspicion of inducing a confession, and, now, the interrogation is no longer meaningful, Chen Yousheng's crime has basically become a fact, and I care more about the test results of the forensic doctor." ”

"What do you mean?"

"Chen Yousheng absconded in fear of crime, was caught red-handed, and important physical evidence was found in his bag. Therefore, this case can basically be closed. As long as we verify that these hemp ropes and knives are related to Qi Wanxin's killing, even if he does not admit his guilt, no one will save him this time. ”

Wu Hao continued to ask, "Did you find anything over there?" ”

"It's not going well." Lin Yuhan said, "There is nothing critical, and I can't figure it out, the office is too messy." ”

"It's not a big deal, right?" Wu Hao didn't care, "It's possible that the victim struggled, fought with the murderer, etc., or the murderer deliberately destroyed the scene in order to destroy the traces of the crime, isn't it normal for the crime scene to be chaotic?" ”

Lin Yuhan said: "No, although this doesn't seem to be much different from other murder scenes, but from these serial murder cases, it is obviously abnormal. ”

"Why?"

"First of all, we can be sure that the murderer certainly didn't come for money, so he didn't go through the cabinets in the office, and the things in the house were thrown everywhere, as if he had entered a thief, which is unreasonable; Secondly, the murderer was extremely ferocious and in good physical condition. Even if there is a fight or argument with the victim in the course of the crime, the scene will not be destroyed like this. So, there must be a conspiracy in this that we don't know about. I think Chen Yousheng's confession is very important. ”

"Important is important, but it does not affect our police to convict him." Wu Hao stretched his waist, as if he had won the battle.

Chen Mengnan walked over and said to the two, "Senior, the test results are out." ”

"How?" Wu Hao couldn't wait to ask.

Chen Mengnan pointed to Qi Wanxin's body and said: "The deceased had emphysema in his lungs, bloody vesicular fluid in his trachea, and spotted hemorrhage in the pericardial viscera and lung mucosa, which is a typical feature of mechanical asphyxiation death. It is now certain that she was strangled to death. Because the neck was cut and the traces of the cause were destroyed, it is impossible to determine the technique of the neck strangulation, but the comparison between the strangulation marks on the wrists and ankles and the tissue cells and fingerprints stained on the hemp rope is indeed Chen Yousheng's doing. And the dagger found in Chen Yousheng's backpack was a tool for cutting the deceased's head. ”

Wu Hao breathed a sigh of relief, with a smug look on his face: "How about Detective Lin, do you have any other ideas?" ”

Lin Yuhan pondered for a long time and replied, "No, but I still want to hear Chen Yousheng's confession." Also, is Li Yue's body still there? ”

Chen Mengnan replied: "It's still there, the case is not over, and the bodies are temporarily stored with me." What's wrong senior? ”

Lin Yuhan said: "I want to see Li Yue's corpse again. ”

"This ......" Chen Mengnan turned his head to look at Wu Hao, "Team Wu, look at this ......"

This is asking for Wu Hao's consent.

"Heh~" Wu Hao glanced at her and said, "If you ask me, I definitely don't agree, how can the victim's body be shown to outsiders casually?" But you are a forensic doctor, the decision is up to you, and what to do with the body is your business, and I can't control it. ”

With that, he turned his head to the side.

Chen Mengnan grimaced at Wu Hao, and then dragged Li Yue's body out of the freezer.

Li Yue asked puzzledly: "Senior, it's been so long, why did you remember." ”

Lin Yuhan lowered his head and replied, "I have some new ideas, I want to look at the situation around the wound and look for more evidence." ”

Two cold, headless corpses were displayed side by side on the dissecting table, making the atmosphere extremely eerie. The incision on Li Yue's body had been stitched up by Chen Mengnan, and at Lin Yuhan's request, she began to remove the stitches.

"Open her chest." Lin Yuhan commanded.

Chen Mengnan divided the corpse's chest into two halves, and the original soft carcass tore a terrifying opening, and the structure in the body was abruptly exposed to the field of vision.

Lin Yuhan said: "Clean up the blood stains around the sternum. ”

Although Chen Mengnan didn't understand, she still did it, took out a cotton ball, carefully wiped the blood stains around the knife edge, and then heard Lin Yuhan's voice: "Stop, this is it." ”

Lin Yuhan lowered his head, took a magnifying glass from the side, and looked at it carefully.

The smell of fish in the air reached his nostrils, but he was not afraid, as if he was identifying the newly unearthed antique, and then, reaching out again, he picked up the minced meat on it, and his brows were furrowed.

"That's not right!" Lin Yuhan stared at the wound and said with a solemn expression, "The deceased was stabbed twice."

"Two knives?" Chen Mengnan came up, "How did the senior see it?" There's only one knife edge. ”

"Here......" Lin Yuhan pointed to his sternum, "When committing a crime, the blade quickly pierces the human body, leaving scratches on the bones. But if you look closely, there is an extra scratch on the bone around the sternum, although the distance is very close, but it is not the same, the strength of the scratch is obviously much smaller than the one next to it, so this knife is a backup, and it is inserted into the body of the deceased along the incision of the previous knife. ”

"It's normal to make up for it." Wu Hao said, "I don't think I'm dead, so I'll make up for it again." ”

"Impossible," Lin Yuhan said firmly, "The murderer's methods are extremely ferocious, and the position is accurate, so that the victim will be killed with one blow, and there is no need to insert another knife in the same position." ”

"And what if the murderer was venting his anger for some kind of emotion?" Wu Hao asked.

Lin Yuhan shook his head: "It's even more impossible, if it's to vent anger, it's not a matter of one or two knives, the murderer will use hard objects on the body of the deceased to output wildly, how can there be only such a slight scratch." ”

The scene fell silent, and the three of them were thinking about the point put forward by Lin Yuhan.

Wu Hao pondered for a moment and said, "Detective Lin, are you thinking too much?" I think there are a lot of possibilities. For example, Chen Xi was seen by Chen Xi after Chen Yousheng killed Li Yue, and then Chen Xi made up for it in order to meet some special psychological needs. ”

"But when you say this, there is no way to explain the problem of fingerprints, and this knife is so close to the wound that if you don't look closely, you can't see the difference at all, I think it's more like it was deliberate, it must have some special meaning."

Lin Yuhan suddenly said to Chen Mengnan: "You bring Li Yue's autopsy report." ”

Chen Mengnan turned around, took out a stack of materials from the drawer and handed it to Lin Yuhan.

Lin Yuhan took it in his hand, kept flipping through it, and when he saw the middle, his hand turning the page suddenly stopped, and then pointed to the autopsy report and said to the two: "No, there is a problem here." ”
