    It took us nearly a day to thoroughly investigate the entire site. As the investigation progressed, puzzling mysteries gradually emerged one after another.

    Since no valuable biological evidence was extracted from the scene, Lao Xian could only go to the funeral home to help Ming Ge, while Pang Lei gathered around the scene intensively to collect surveillance cameras along the way, because A Le and I were in the same office, and Ming Ge  We were directly arranged to work in pairs and started with trace inspection.

    "What to do next?" A Le looked at the latex gloves on his hands repeatedly as if he were looking at a rare item.

    "There are two important tasks that we need to complete."

    "two?"

    "Yes." As I said that, I took out a plastic box from the survey box.

    "this is?"

    "The fingerprint skin cut from the deceased's finger is also called a 'leather glove'."

    Ale pretended to be calm and said "oh".

    "I'll soak the 'leather gloves' in ethanol for a while and deal with them later. The most important thing now is to deal with this!"

    "Glass? How to fix this?"

    "set up!"

    ¡°I x, you¡¯re not mistaken, it¡¯s all broken into pieces like this, how do you put it together?¡±

    "Of course I have a way!"

    ¡°I really admire you technical people!¡±

    "What are you doing?" Seeing A Le turning to leave, I shouted to him.

    ¡°I don¡¯t know how long we¡¯ll have to fight for. I¡¯ll go out first to have a cigarette craving before I come in. Do you want to join us?¡±

    "Yes! I'll accompany you!" I took off my cotton gloves and threw them on the workbench, followed closely.

    Night had fallen. We were holding cigarettes in our mouths, lying on the corridor on the second floor and looking towards the yard. Maybe we were moved by the scene. The scene where Ale rescued me half a year ago flashed before our eyes like a movie.

    "Ale, can I ask you something?"

    "what's up?"

    "Why did you come to our department? I mean, maybe you will have a better future in the criminal police team, don't you think?"

    A Le turned to look at me and raised the corner of his mouth: "Do you really want to know?"

    "Yeah!" I nodded without denying it.

    "Okay, I'll tell you, but now is not the time! When the case becomes clearer, let's sit down and have a good chat, how about it?"

    "no problem!"

    After the topic was over and half of the cigarette was left, Ale started again: "Xiaolong, the glass is broken like that, can you really put it back together?"

    When it comes to the field of trace science, I am quite confident: "It may seem a bit confusing to outsiders, but in my opinion it is not difficult."

    "Just blow!" A Le leaned against the window frame and flicked the cigarette ashes.

    Ye Qian doesn¡¯t know how many times I have used this kind of provocative method on me, but it still works every time.

    ¡°If you want to know the reason for this, you really have to start with the glass production process.¡±

    "Oh? Come and listen?"

    "What we extracted at the crime scene were flat glass fragments. The main raw materials of this glass are quartz sand, soda ash, Glauber's salt, carbon powder, broken glass, dolomite, and limestone. We mixed all the raw materials in a certain proportion and put them into the kiln  Calcination, when the temperature reaches 1000 degrees Celsius, the solid raw materials will melt into liquid glass water. The glass water is injected into the molding machine, and the molding machine produces the glass plate according to the selected size. The glass plate then enters the lead-in machine and is installed on the lead-in machine.  There are asbestos rollers. When the glass plate passes through the loading machine, due to the extrusion of the asbestos rollers, linear traces with uneven density will be formed on the glass plate. Such traces are difficult to identify with the naked eye, but they are quite visible under a comparison microscope.  Obviously, these strips of bulges are called 'glass tendon traces' in trace science. As the name suggests, the traces are like glass 'stretch's."

    ¡°The secret lies in these ¡®glass tendon traces¡¯?¡± Ah Le listened with great concentration.

    "Yes, when the glass plate that has not been completely cooled is squeezed by the asbestos roller, it will often form multiple 'glass ribs', and each 'glass rib' will not be exactly the same. As long as I can find these 'glass rib traces'  , you can easily put the broken glass back together.¡±

    "But even if we put the glass together, what's the use?"

    "I suspect that there will be important physical evidence left on this broken glass."

    "Physical evidence?"

    "Judging from the degree of shattering of the glass, it is obvious that the suspect did it deliberately, basically ruling out the possibility of accidental drop and shattering."

      "Well, this is easy to understand."

    "Have you ever thought about the suspect's purpose in deliberately destroying this piece of glass?"

    "Purpose? What purpose can this have?"

    "If my on-site analysis is correct, the window opening tool used by the suspect should be a round glass knife. The end of this glass knife has a large suction cup. Once the suction cup is attached to the glass, it will take a lot of effort.  It requires strength to pull it off. It is very easy to slip when wearing gloves. The usual method is to increase the friction by relying on the palm lines. In other words, the suspect may not have worn gloves when removing the piece of glass. If this makes sense  , then it is not difficult to understand that the suspect has an additional action of smashing the glass."

    "Well, that makes sense!" Ah Le finally turned the corner and asked again: "The glass has been smashed like this, so aren't the fingerprints finished with it?"

    "This is what I'm worried about, but as long as possible, we will give it a try."

    "I just fucking admire the energy of the people in your department. Let's go get to work!"

    "It's much more difficult to piece together the glass fragments than I thought. It may be that the suspect used too much force. Powdered glass accounts for a large proportion. No matter how hard I try, I can only piece together a rough idea."

    Ah Le looked at the piece of glass with seven holes and eight holes on the operating table, and asked with some uncertainty: "Is this the result of the spelling?"

    I let out a long sigh and nodded helplessly: "This is the best result. I can only wait for a miracle to happen."

    "What other flowers do you want to play with?"

    "The glass has been broken into pieces like this. There is no need to extract fingerprints through normal methods. I need to move this to the iodine fumigation box for processing."

    "Is it possible that this can really process fingerprints?"

    "If I'm right, maybe it can be done at the edges."

    A Le didn¡¯t answer any more, his expression seemed to say: ¡°It¡¯s okay if you say it, but I want to see if the result is so miraculous.¡±

    How did he know that the people in our department are all from the "Focus Interview" group and can only "speak with facts."  The spliced ??glass plates did not disappoint me. Not long after being placed in the heated iodine fumigation box, several incomplete fingerprints appeared on the edges of the glass plates.

    "Really? Can you stop being so awesome?"

    "It's just a simple principle." Although Ah Le often shows a cynical attitude, I am not disgusted with him. I was probably influenced by the movie "Young and Dangerous" since I was a child. I also quite admire his personality. Sometimes I even feel  , Ah Le¡¯s character is very similar to the movie¡¯s male protagonist Chen Haonan, and his ruffian sense of justice does have a special charm, so no matter how arrogant Ah Le behaves, I am very willing to teach him everything I can, for a short time.  After a pause, I continued: "Due to metabolism, there will be secretions such as oil and sweat on human hands. When the fingers touch the glass plate, the oil and sweat will remain on the glass plate. When the iodine is heated,  As ethanol volatilizes, iodine vapor also volatilizes. Iodine dissolves in grease, and iodine vapor will dissolve in the fingerprint lines containing grease, forming brown fingerprints. This method can even detect fingerprints several months ago.  .¡±

    "Yes! Understood! But how are you sure these are the fingerprints of the suspect? What if they are the fingerprints of the resident?"

    "No, look at the distribution of these four incomplete fingerprints. They are all concentrated around the circular glass plate, and they are all lines on the belly of the fingers. If my guess is correct, the suspect should have one hand at that time.  Grasp the circular glass plate and pull out the suction cup with the other hand. Only in this way will the current fingerprint distribution be formed, so these four fingerprints can only be left by the suspect."

    "With fingerprints, can we solve the case?"

    "It can only be said that we have a grasp for the time being. Whether the case can be solved remains to be seen." (Remember the website address: www.hlnovel.com
