    "Teeth bite marks?" Ye Qian asked habitually.

    "Yes." I took out the cigarettes from the cigarette case and distributed them.

    ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? I lit the cigarette in my hand and took a long puff as a demonstration.

    "You also noticed my action just now. The normal way for people to smoke is to hold the cigarette with their fingers and put it into their mouth. Under normal circumstances, we hold the cigarette with our lips, take a puff and then take the cigarette out of our mouth with our fingers.  come out."

    "Well, this is the right move." Pang Lei followed my movements and gestured.

    "In other words, most people will not use their teeth to bite cigarette butts, so they will not leave bite marks on the cigarette butts. But if you look at these three cases, all the cigarette butts at the scene have serious tooth bite marks.  This reflects the suspect's habitual actions. During the smoking process, he would not pick up the cigarette with his hands, but chose to bite the cigarette butt with his teeth to summon air."

    "What does this mean?" Ye Qian still didn't understand what I meant.

    "It is not difficult to tell from the number of cigarette butts left at the scene that he must have been very addicted to smoking. During the process of squatting, he only needed to use his eyes to find the target. He could have used his hands to catch the cigarette, but he did not do so  Yes, this shows that the suspect has this kind of smoking habit. Then let¡¯s analyze, who has this kind of smoking habit?¡±

    When Brother Ming heard this, his brows were completely relaxed. It seemed that he already knew what I was going to say next, while the other three still looked like they didn't know anything.

    I continued: "In our trace science, there is a special list of people who have this habit. For example, shoemakers, their hands need to constantly nail shoe soles and sew shoe uppers. If they get addicted to smoking while working,  They don¡¯t have time to hold the cigarette with their hands, so they have to hold it with their teeth, leaving bite marks on the end of the cigarette.¡±

    "There are also carpenters. They cannot do without their hands when sawing piles and planing wood. If they want to smoke, they can only rely on their teeth."

    "Finally, there are masons. They usually have to deal with cement. As long as they work, their hands and clothes will basically be covered with cement. And we all know that cement will solidify when it comes into contact with water, and the same goes when it comes into contact with saliva, so masons generally  They like to hold cigarette butts between their teeth and smoke. Of course there are other situations where this habit develops, but these three professions are the mainstream."

    "That means the suspect is either a shoemaker, a carpenter, or a mason. This is too broad!" Ye Qian didn't buy my reasoning.

    "I'm not finished yet."

    I pressed the cigarette butt in my hand into the ashtray and continued: "Let's take a look at the locations of these three cases. One is in the west of our city, one is in the east of our city, and the last murder is in the south of our city.  And they are dozens of kilometers apart. Why did he choose these locations to commit the crime? If he only targeted female students, there are so many schools in our city center, why did he choose to go far away?"

    "Does he have three families?" Ye Qian said nonchalantly.

    "He has three homes and still wears such shabby clothes?"

    "Then why do you think it is?"

    "It's very simple. I suspect that he happened to be working nearby when he committed the crime!"

    "Working?" Ye Qian's eyes widened.

    "Yes, and my reasoning is well-founded and not groundless. Let's take a look at the time between the three cases. The first molestation case was on January 16, the second rape case was on January 24, and our murder case  It¡¯s February 1st.¡±

    Ye Qian listened to me telling me the date and started counting on her fingers.

    "There are exactly seven days between the three cases?"

    "Yes, seven days. I suspect that this number was not intentional by the suspect. It is most likely his construction period."

    "Construction period?"

    "You will understand after you listen to what I have to say." I changed my sitting posture and continued:

    "If the suspect only committed crimes in a targeted manner, he would not choose to commit crimes at such a dispersed distance. The only explanation is that he came here to work and committed crimes by the way."

    "Well, there is such a possibility!" Brother Ming nodded.

    "Let's look at the time of the crime. Basically, it is when students go to school. Because we know that students finish school at the same time, so there will be a phenomenon of many people crowded together. It is difficult to start, and only  When going to school, students tend to be left alone. According to the materials from the on-site visit, one of the three schools is a provincial key, one is a municipal key, and one is a district key. The three schools have completely different starting time for evening self-study. Why?  Ability??Hold so accurately?  "

    "He visited the site many times beforehand?"

    "Yes, I also doubt this. This shows that the suspect came to the crime scene more than once during the crime, knew the time when the students went to school, chose to commit the crime on the last day of the work period, and then left here and moved to another place to continue.  This pattern of committing crimes is why the current situation appears.¡±

    "Well, that makes sense!" Brother Ming said approvingly.

    "Since my hypothesis is established, the suspect cannot be a shoemaker, because we have never heard of shoemakers traveling around. Most of them work in fixed places. And I have carefully compared the three cases.  There are a large number of construction sites around the location, and the suspect is likely to be a person working on the construction site. This can basically rule out that he is a shoemaker. Otherwise, there are only two mainstream occupations: carpenters and masons."

    At this point, I looked up and found that the four of them had been listening intently. I cleared my throat and started to talk about the core part: "The suspect moved to one place for seven days. If it is a large construction site, it is impossible to do that."  It¡¯s short, and it¡¯s so fixed. So besides large construction sites, what other construction sites would use carpenters or masons?¡±

    "Decoration?" Ye Qian finally had an idea.

    "Yes, decoration! Generally, there are several types of work involved in the process of home decoration, such as bricklayers, plumbers, carpenters, and painters. Let's analyze them one by one."

    "Plumbers mainly cut walls and lay wires and pipes during their work. They will splash a lot of dust during their work, so they will not smoke during work, so they will not develop the habit of biting cigarette butts with their teeth.  The same goes for painters. Their main job is to spray paint with professional spray painting equipment. They usually wear masks during the work, and they are not likely to smoke, so it can be ruled out."

    "Carpenters may develop the habit of biting their teeth and smoking while working, but if we carefully recall the descriptions of the victims in the first two cases, they both mentioned that they saw the suspect's body covered in gray.  Note that what the victim wants to express is that there is too much dust, and if it is a carpenter, then he should have sawdust on his body. This is one. Second, carpenters account for a large proportion in the entire decoration process.  We need to make suspended ceilings, furniture, and some even make bathroom cabinets. Of course, these must be done according to the employer's requirements, so the construction period is basically between half a month and a month, and some even take more than two months.  Therefore, their construction period is the least fixed and can basically be ruled out.¡±

    "The only remaining ones are most likely masons. During their work, they only have some dust when working with cement. In other cases, the working environment is relatively clean. It is not a big problem to smoke with your mouth.  The dust described by the victim may be cement dust."

    Having said this, I stood up, took a glass of water from the water dispenser in the conference room to moisten my throat, and continued: "There is another thing that can prove that the suspect is engaged in decoration, and that is the butts of high-end cigarettes left at the scene. In large-scale  When working on construction sites, masons basically work with foremans, and they are not willing to give good smoke to the migrant workers under them. They can only do decoration, and the employer wants the workers to do their work more meticulously and give the workers some good pay.  Smoking is also a normal phenomenon. This can just explain why high-end cigarette butts are left at the scene."

    ????????????????????????????????????????????????????????????????????????????????????????????!  After hearing this, Brother Ming applauded me vigorously.

    ¡°There is indeed nothing wrong with Master¡¯s genes!¡± Fat Lei slapped me on the shoulder and said with a smile.

    Lao Xian gave me a thumbs up. Even Ye Qian, who had always been against me, admired me.

    I enjoyed this atmosphere very much and continued with a smile: "So the following investigation work is very targeted. The suspect committed the crime on foot, which means that he is not very far from the crime scene. We only need to conduct the investigation around the scene. See  Check to see if anyone is renovating around, and they were doing brickwork seven days from the time of the crime. If so, cross the three crime scenes to find the reoccurring decoration team, then the suspect is among them.  !¡±

    ¡°This is much more reliable than finding a fish pond in the village!¡± Fat Lei slapped the table and shouted excitedly.

    "Ye Qian, I'll leave it to the criminal police team from now on!" I closed the notebook and said.

    "I believe there will be results soon." Ye Qian looked happy.  (Remember the website address: www.hlnovel.com
