    Teacher Li Feng walked back to the footprint lamp and said, "Our topic has gone a little far. Now let's take a look at the series of shoe prints at the scene. They are all clear in the middle and blurry on both sides, which is consistent with 'small feet wearing big shoes'"  characteristics, so I concluded that this was a 'disguised shoe print'. Generally only suspects would do this kind of thing, so I can judge that this string of shoe prints was left by the suspect."

    I glanced at the teacher who was taking pictures of the footprints and said doubtfully:

    "If the suspect has 'big feet wearing small shoes', I can easily understand it. Although the shoes squeeze the feet, at least the shoes will not get in the way during the escape. Once this 'small feet wearing big shoes' is discovered, the shoes will not fit the feet.  , can¡¯t even run away. Why would he do this?¡±

    ¡°It¡¯s definitely hard to explain this phenomenon alone. Let¡¯s process all the physical evidence and we¡¯ll be able to find clues.¡± Teacher Li Feng put down the camera in his hand and answered.

    "Okay!" I mustered up my energy and made a "come on" motion with my right hand.

    Because the forensic doctor in the department is not here, everything needs to be explained using trace science. Teacher Li Feng did not dare to neglect. He extracted all the traces himself, while I worked on it carefully.

    Three hours later, all the physical evidence extracted at the scene was brought back to the laboratory for examination.  Because it is in a mountainous area with rugged roads, the technical room here is equipped with a special dissection room, so the corpses at the scene were also brought back.

    Whenever a case involves human life, the first step is to look for clues from the corpse.  Although Teacher Li Feng is an expert in trace examination, he also knows some forensic knowledge. As an excellent technician, he must be involved in various subject areas.

    I followed him into the anatomy room.

    After we were fully dressed, Teacher Li Feng opened the blue body bag with a squeak.  I frowned and looked at the white fly maggots squirming back and forth on the corpse's face, and goosebumps stood up all over my body.

    Teacher Li Feng used tweezers to pick up a few maggots from the corpse and placed them on the iron tray on the left. Then he observed them for a while and then said to me: "The deceased died three days ago."

    "Teacher, how are you sure?" I walked up to him in two steps and stared at the maggots in the tray curiously.

    "Is it because of this?"

    "Yes, I deduced it from these maggots." Teacher Li Feng pulled off his mask, nodded and said to me.

    "Teacher, tell me quickly!" I urged from the side with an eager look on my face.

    Teacher Li Feng put down the tweezers in his hand, pointed at the milky white maggots in the tray and said to me:

    "After a person dies, there will be insects parasitic on the body within a few hours, and the more common ones are flies. Especially in indoor scenes, the surroundings are closed, and there will be no other insects living on the body, so I can use  Let the flies judge. The growth process of flies is generally that fly eggs hatch into larvae, the larvae pupate, and the pupae grow into new-born flies. During the period when the body is not found, the whole cycle will be repeated."

    "Flies like to lay eggs in holes or wounds on corpses. Usually, if the temperature conditions are suitable, the fly eggs will hatch after 8 to 14 hours, and the first batch of maggots will appear."

    "The first development stage will last eight to 14 hours, and then the maggots will shed their skin. This process will last two to three days, and then the maggots will turn milky white. The next stage of development, these milk  The white maggots will eat the corpse crazily for about six days, and then transfer from the corpse to the ground, where they will pupate. The general cycle from egg laying to pupation is eight days. After pupation, they will pupate again.  In 12 days, you can turn into a fly."

    "Let's take a look at the maggots on the face of the corpse in this case. They are all milky white, and judging from the length of the maggots, they only have three days to grow, so I can roughly judge the time of death of the deceased."

    "Teacher, you are really humble, and you said you are not good at forensic medicine!" I said with admiration.

    "This is all taught by your father!" Teacher Li Feng said to me with a raised corner of his mouth.

    When I heard the word "father", my heart couldn't help but twitch. The scene of my father sitting on the bedside, reading books with saliva on his face, came to my mind.

    Teacher Li Feng took advantage of my daze to brush off the maggots on the corpse, then took off all the clothes of the deceased and began to examine the condition of the corpse.

    "Judging from the body spots, it matches the characteristics of hanging." Teacher Li Feng's words brought my consciousness back to the case.bsp; "Let's calculate the difference now. The total height is 419 centimeters, minus the length of the rope loop 123 centimeters, minus the length of the body 162 centimeters, and then minus the height of the bench 74 centimeters. What is it?"

    While listening, I quickly took out my phone and turned on the calculator. As soon as Teacher Li Feng finished speaking, I reported a series of numbers: "Teacher, exactly 60 centimeters."

    Teacher Li Feng took a look at the numbers on my phone and said to me: "That is to say, the deceased was standing on the chair, and there was a 60 cm drop between the top of his head and the bottom of the rope loop."

    "Teacher, I have a question." I interrupted.

    "you say."

    "If the deceased stood on tiptoes and stretched her arms, would she touch the bottom of the rope loop? If she could, she would just need to use her hands to grab the rope loop with a little force, and it seemed that she could put her head into the rope loop. Of course.  , This is just assuming that the deceased committed suicide." I expressed my thoughts.

    Teacher Li Feng seemed to have been prepared. He smiled slightly and said to me confidently: "Look at the length of the deceased's forearm and the length of the deceased's shoes. Report these two data to me."

    Well, I rolled the records hard and looked carefully.

    "With a teacher, the forearm is 24 centimeters long and the shoes are 22 centimeters long."

    "Well, the wingspan of a normal person's two arms is about the same as the person's height. But if you raise your hands to perform some kind of work, the actual 'working distance' of the person's arms is only the length of the forearm. In other words, you  Raise your hands above your head. At this time, the total length is basically equal to the length of your forearms plus your original height. The deceased stood on tiptoe, which was only 22 centimeters at most. She couldn't have learned ballet, so she stood up on her toes, right?  "

    "Even if calculated according to the extreme figures, using the height difference of 60 centimeters and subtracting the length of her forearms and shoes, there is still a drop of 14 centimeters. This gap is insurmountable by the deceased. From this we can judge  , the rope loop on the beam could not have been tied by the deceased himself. The person who tied the rope loop was at least 14 centimeters taller than the deceased, which means that his height was more than 176 centimeters. But this number is when he raised his hands and pointed.  If the value of the point touching the bottom of the rope loop is based on the actual situation, the suspect may not be less than 1.8 meters." Teacher Li Feng's thinking was extremely quick, and I was dumbfounded.  (Remember the website address: www.hlnovel.com
