MTL - Mystery Hunter-Chapter 11 corpse traces

At four o'clock in the afternoon, a complete autopsy report appeared in front of Jiang He and others.

Xu Yiman took the autopsy report and said to the crowd: "The complete autopsy report has come out. Before we took the blood of the cadavers, liver and kidney cells, etc. for testing, and found that there was no drug ingredient in the blood of the two cadavers. , and no signs of poisoning were found in liver and kidney cells."

Xu Yiman quickly flipped through the autopsy report and told everyone the important parts: "And the brain autopsy found that the two did not suffocate before their lives, which means that."

Jiang He opened his mouth and said, "And this means that both of them died when they were awake, and there was no murder after fainting. But when I was at the scene, I carefully observed the situation of the two corpses. Wu Guifeng and He Huijuan There is no sign of struggle before death."

Jiang He analyzed one by one: "On the bed where He Huijuan is lying, the sheets are relatively flat, and He Huijuan's hands are flat on both sides of the body. From my experience, even if the heart is directly stabbed, There are also seconds to react, let alone a knife in the stomach."

"Then the only explanation is that someone sorted out the traces of the scene afterwards." Jiang He's eyes were burning: "I am 90% sure about this. If we use this as a basis, then we can infer a conclusion. , isn't that serrated knife mountain only one person's fingerprint?"

Hearing Jiang He's words, Wang Chao hurriedly flipped through the on-site trace record sheet, and he nodded abruptly: "You're right, after investigating the serrated knife for physical evidence, it was found that there was only one person's fingerprint on this knife. After comparison, It was found to be Wu Guifeng's own fingerprints."

Having said this, Wang Chao said again: "From the overall information we have obtained, it is basically clear now. Think about it, the door is locked, and even if there is a key, there is no way to get out from the outside. Open the door, and the resident is on the sixth floor. If there is a murderer, this operation is too difficult. Besides, both of them are awake, even if they are no match for the murderer, at least breaking the glass and shouting can always be done. "

"Besides." Wang Chao pointed to the information on the record sheet: "On the knife there is only Wu Guifeng's fingerprints. Isn't this all iron-clad evidence?"

Jiang He shook his head like a rattle: "No, I'm missing the most important point. What about the phone, what did Li Weiyi say about it?"

Wang Chao replied: "Li Weiyi said that he went out at about seven o'clock in the morning, and he didn't notice He Huijuan's cell phone when he left. He said that He Huijuan was a night owl, and usually after she went to bed, He Huijuan would play with her cell phone under the quilt. He often dropped his phone while playing, and he didn't care about these things. So Li Weiyi didn't know whether He Huijuan's phone was lost or what happened."

"In short, the mobile phone is a very important point." Jiang He said, "It is impossible for a mobile phone to disappear. If we find the mobile phone, we will also find the one most likely to be the murderer."

Xu Yiman shook the report in his hand and made a sound of paper rubbing. Everyone's attention returned to Xu Yiman. Xu Yiman cleared his throat and said, "This autopsy report is not over yet. "

"Through my autopsy, I found that He Huijuan had sexually acted before her death." Xu Yiman's voice was not loud, but every word was clearly transmitted to everyone's ears.

Although there is no taboo in solving the case, what is the truth, that is what it is. But a few big men were still a little shy when they heard this. They all pretended to look at the scenery, as if they didn't hear what Xu Yiman was saying. Jiang He was not at all shy, but asked openly, "Is it possible to tell if you had **** before death? How long was the interval between death and whether the female corpse was detected?" Are there male sperm in the body?"

Jiang He's straightforward questioning made the surrounding detectives feel that the scale was too large. If it were changed to the previous law-medical Lao Li, and everyone was a man, these problems would be fine. After all, it was Lao Li who was embarrassed during the autopsy. one person. But standing in front of him was a beautiful and **** female forensic doctor aged 27 or 8, which was very embarrassing.

Xu Yiman is accustomed to this. After all, since college, he has dissected all kinds of corpses, men and women, young and old. Xu Yiman can say this, the corpses she has dissected are better than these fresh ones. The little policemen who came have seen many corpses.

Xu Yiman answered Jiang He's words one by one: "First of all, as long as it doesn't pass too long, whether the deceased had sexual **** before his death can be determined through anatomy. For example, the contraction of the cervix, such as the secretion of estrogen. After a series of comprehensive examinations such as increase, whether it secretes body fluids, etc., the problem you mentioned can be found out."

"The second one." Xu Yiman is like a teacher in class: "I can't make a specific time conclusion for your second question, but the time interval must not be long. If you want me to give a If it is within the range, then it should be within the two-hour range.”

Xu Yiman is very serious: "When a woman has sexual intercourse, her lower body will return to its original state within a period of time. Obviously, according to my anatomy, the deceased's lower body has not recovered. It is already dead in normal times. After a person dies, the muscle tissue of the corpse will generally be finalized in the final state of death. If the corpse is not deliberately processed, it can still be found out. Fortunately, the two we encountered It didn't take long for the body to die, and many things could be found out."

"Finally." Xu Yiman sighed: "I didn't find any male body fluids in the secretions of He Huijuan's lower body. But I found glycerin, propylene glycol and other ingredients."

"Lubricant?" Jiang He blurted out.

Hearing Jiang He's words, Xu Yiman's eyes lit up. Ordinary people would never know what these chemical ingredients are used for, but Jiang He in front of him actually knew, which made Xu Yiman feel a little bit of a bosom friend.

Xu Yiman nodded: "Yes, this is the basic ingredient of lubricating agent. But it is not necessarily a specially bought lubricating agent. Most condoms now have such ingredients."

Jiang He slammed the table on the table and said, "The deceased had sexual **** before he was alive, but there was no sign of struggle. If it was a room entry, **** and murder, the scene couldn't be like this. According to the time, that The time is between ten o'clock and eleven o'clock. At this time, there are many people outside. According to my experience, few criminals choose to commit **** at noon. According to the comprehensive calculation of these points, I have a percentage of Eighty percent believes that the murderer and He Huijuan must be acquaintances."

"What do you mean." Wang Chao wanted to say something, but he glanced at Xu Yiman and hesitated.

"Just say what you want to say." Xu Yiman said, "I haven't seen anything as a forensic doctor."

Only then did Wang Chao continue: "You mean He Huijuan cuckolded Li Weiyi?"

Jiang He said, "Based on the current situation, this possibility accounts for 30%."

"The probability is so low?" Wang Chao said, "What about 70 percent?"

Jiang He said, "The remaining 70% is not another possibility. After throwing away those probabilities that basically can't be counted, there are still several possibilities."

"Ten percent." Jiang He said, "It doesn't necessarily have to be a man. Putting a condom on any object may create such an effect. It may be that He Huijuan, after masturbating, Killed. Another 20%, He Huijuan was coerced. If she didn't agree, she would kill her, so she didn't dare to struggle, she just asked the other party to leave as soon as possible, but He Huijuan was killed in the end."

After a pause, Jiang He continued: "For the remaining 40%, Li Weiyi came back at noon. According to my survey of Li Weiyi's career, Li Weiyi only needs to clock in when he goes to work and clock in when he gets off work. The time of day can be arranged freely, which means that Li Weiyi has time to commit crimes."

"What's the motive for committing the crime?" Xu Yiman said, "Why did he kill his wife and mother?"

Jiang He shook his head and said, "According to my investigation of the scene, Wu Guifeng committed suicide. When analyzing, you must first separate Wu Guifeng. Also, I never analyze how a person thinks. , because I don't understand, and I can't analyze it."

Jiang He looked around at everyone: "The world is rational and emotional, I will only analyze general characteristics through the information on people, for example, this person is always working, we say he is a workaholic, for example, this person always likes Peeking at the bottom of a girl's skirt, we say he's a voyeur."

"But." Jiang He said, "That's all I can analyze. I have no way of knowing why he is always working, and I have no way of knowing why he is so fascinated by girls' bottoms~pants. This is the story of their inner world. , and this kind of thing is often impossible to analyze.”

Jiang He spoke slowly, unable to tell what kind of mood he was in at the moment from the tone of his voice: "What is thinking in people's hearts, this is something that can never be analyzed, and it will confuse us the most. It is the thing that solves the case, so we need to dig out the factors of people's hearts, and what we get is the truth that is closest to reality."

"Because people can deceive people, but the evidence left at the scene will not deceive people." Jiang He said.

Wang Chao listened to Jiang He's words, but he had a different opinion from Jiang He: "This time, what you said is not comprehensive. When I was a student, I took an expert's class. What is the name of that expert? I don't remember this clearly. But he is the kind of person who can read your inner thoughts. He is very powerful. This expert was also a very powerful criminal policeman when he was young. I am not targeting you, but I think he can see the scene. There are a lot of good people who have traces, but not many who can read people's hearts."

"Is there such a person?" Jiang He asked.

Wang Chao nodded again and again: "Of course there is, as you said, the evidence is dead, the person is alive, and he can see through his secrets at a glance from such a complex and changeable heart, this is a truly powerful detective. ."

Having said this, Wang Chao sighed again: "It's just that such a person is too far away from us, I can't reach it in my life, but you have more talent than many people..."
