    ????????????????????????????????????????????????????????????????????????????????????????????? away from the murder case, I discovered a very strange phenomenon. The smoother the investigation, the more unsatisfactory the answers I get. This case has not been able to escape this curse.  After three days of investigation by the criminal police team, all the clues given by Brother Ming were revealed.

    The three people who were drinking with the deceased that night were all ruled out as suspects after Lao Xian¡¯s DNA comparison.  The regular customers of Madam Guan Wenjuan also have alibi.  Moreover, the deceased was much more restrained in Yunxi City than we thought. She usually only occasionally chatted with some regular customers in a lukewarm manner, and no other abnormalities were found yet.  After all the issues had been investigated, Mingge presided over a project meeting.

    "The autopsy determined the cause of death, mechanical asphyxiation, and the death tool was a red rope tied to the deceased. The time of death was determined to be around 2 a.m. on July 9. Except for bump injuries, there were no obvious resistance injuries on the deceased.  , from this point it can be seen that the suspect had tied up the deceased before committing sexual assault.

    "The body showed convulsions. It is suspected that the deceased was frightened before death. It is analyzed that the sexual relationship between the suspect and the deceased was not voluntary. Thinking about it from another perspective, only when the deceased was unconscious, could the suspect have done so much before the sexual assault.  preparations."

    I added: "In the past two days, I have carefully analyzed the gait characteristics of the deceased. I can be very sure that Guan Nianqiu's gait when entering the room could only be formed when he was in a coma or semi-coma state."

    Brother Ming continued: "The autopsy confirmed that the deceased had indeed consumed a large amount of beer, but according to the Madam's confession, the wine was not enough to make the deceased unconscious, and no trauma that could cause coma was found on the body, so  " Brother Ming looked at Lao Xian.

    Lao Xian understood: "I extracted a high concentration of ethanol from the deceased's mouth. I suspect that the deceased not only drank beer, but also drank a large amount of liquor."

    "And liquor? Didn't the Madam say there is only beer?"

    ¡°It¡¯s not unusual to bring your own drinks to a nightclub.¡± A Le¡¯s words suddenly enlightened me.

    "This can explain why the deceased was unconscious. To put it bluntly, it was caused by alcohol." I snapped my fingers.

    Lao Xian¡¯s expression was solemn: ¡°But when I examined the stomach contents of the deceased, the ethanol concentration in his body was not that high.¡±

    "This is easy to explain." A Le said with a battle-hardened look, "I have met this kind of person. He can hardly get drunk after just drinking beer, even just drinking liquor. But if he drinks liquor after drinking beer,  , maybe he couldn¡¯t bear it after a few drinks. This kind of person can¡¯t mix wine, and he will get drunk easily when he mixes wine. Maybe the deceased was such a person. "

    Ah Le¡¯s explanation is absolutely reasonable. There are many people in the wine shop who cannot mix alcohol with alcohol. This is not the first time I have come into contact with them.  In fact, there is such a sentence in "Qing Yi Lu" written by Tao Gu during the Northern Song Dynasty: "Do not drink mixed wine. Drinking it will make people drunk even if they are good at wine It is a taboo for drinkers." Mixing wine with wine can easily make you drunk.  This is a conclusion reached hundreds of years ago.

    According to current research by some experts and scholars, beer and liquor mixed together are the most likely combination to cause a drunken reaction. The reason is that the ingredients of liquor and beer are very different due to their production processes.

    The main process of liquor is distillation, while beer is fermentation. Different processes lead to different ingredients of the two wines.  In addition to a small amount of fusel alcohol, liquor is mainly ethanol, while beer contains much richer ingredients, including carbon dioxide, peptides and amino acids, inorganic salts, vitamins, antioxidants such as polyphenols, many of which can promote  Absorption of ethanol.  It will make the drinker feel intoxicated early, and in more serious cases, it may even cause poisoning symptoms such as dizziness, nausea, and vomiting.  Although according to the confession of the old bustard Guan Wenjuan, the deceased drank more than ordinary people, but if she was easily drunk with alcohol, it is not ruled out that she would be drunk.

    "What A Le said is possible." Ming Ge was the first to agree.

    Because this issue did not dominate the investigation of the entire case, we did not dwell too much on it and the meeting continued.

    "There are roughly only so many autopsies, Xiaolong, go on."

    "No signs of prying were found on the door at the center. Through shoe print analysis, it was found that the deceased and the suspect entered the room together. In other words, the suspect may have used the deceased's key to open the door. Later, I opened the door with the deceased's key.  This was proven by the suspect's fingerprints found on the leather key bag.

    ¡°Then I extracted a total of two traces indoors: fingerprints and shoe prints.

    "Let me talk about the shoe prints first. The shoe prints indoors are very clear and distributed in dots. The suspect is wearing spiked shoes, and the shoe prints showThe physical characteristics of ?? are only some irregular dot-like patterns, which is difficult to use for comparative analysis.

    "Fortunately, the shoe prints indoors are relatively clear. By measuring the suspect's step length and step angle, combined with the gait characteristics, I came to a preliminary conclusion: the suspect is a male, over 1.8 meters tall, with a strong body. According to  Foot pressure analysis shows that young adults are more likely to have it.

    ¡°There are only so many conclusions drawn from shoe prints, the rest are fingerprints.

    "According to the distribution of fingerprints, all the home furnishings in the room have been turned over, and the deceased's mobile phone, wallet and jewelry were stolen. The phenomenon of property embezzlement is obvious. From this point of view, the suspect's economic conditions may not be very good.

    "And I also discovered a strange phenomenon. There were a large number of craft ornaments placed in the rented apartment of the deceased, including ceramic dolls, music boxes, etc. I also extracted the suspect's fingerprints on these small things, especially on the music box.  The superimposed fingerprints on the knob were quite obvious. The suspect had turned the switch of the music box more than once.

    "According to the distribution of shoe prints, these additional actions performed by the suspect were all after the rape and murder. According to normal people's thinking, there are only two possibilities for the suspect to be so calm: first, he himself has become numb to it.  Have strong counter-investigation experience; secondly, the suspect is very curious, reflecting a very immature mind.

    "The first situation is obviously impossible. We have never received a similar report before, and the suspect cannot be numb to it; if the suspect has strong anti-investigation capabilities, he will not leave a large number of people at the scene.  There are traces of physical evidence, so I guess that the suspect may be a young adult who is short of money, curious and immature."

    "That's reasonable!" Brother Ming nodded.

    "Guoxian, please tell me."

    Lao Xian pushed up his glasses as a signature action before starting the lecture: "All the biological materials I extracted confirmed that the suspect is one person, male, and the DNA information is not available."

    "The first step is to test for sperm spots. Based on the analysis of the residual amount of sperm spots on the deceased's vaginal swab and the sheets at the scene, the suspect's ejaculation volume that night should be more than 20 ml. Calculated based on the normal male ejaculation volume of 5 ml.  The suspect may have had sex with the deceased many times in a short period of time. According to the male's physiological characteristics, the suspect has a strong sexual desire and a great desire for sex. The suspect may be a single young man.

    "Then, I extracted the suspect's saliva spots from the deceased's lips, chest and perineum. This only proves some of his actions when committing the crime and does not bring substantial detection to the case. The suspect used  The ropes used to bind the deceased were ordinary cotton ropes, which have a high distribution rate on the market and have no comparative value. I have only analyzed so much of them so far."

    "Jiao Lei, tell me."

    "His grandma, why do I feel that this case is getting more and more mysterious." Fat Lei directly swore.  (Remember the website address: www.hlnovel.com
