    The Shancheng community where the crime occurred is also a relatively well-known residential community here.  Back then, this place was so hyped that the developer once asked for a price of 8,000 per square meter. In a big city, the price might be less than a fraction, but in a third-tier city like ours, it is already considered a high price. Today, the price here is  The average price is only a little over 5,000.

    The biggest highlight of Shancheng Community is that it is built on the mountain. Judging from its brochure, the scenery is breathtaking.  But the developer seems not to have considered the most important point, which is safety. About three years ago, a landslide occurred on the south side of the community, which directly caused serious damage to some houses at the foot of the mountain and injured many people. This incident caused a lot of trouble.  There was an uproar, and the contractors and developers of the community were held accountable.

    And this incident was just the beginning. Later, because of this community, a case of corruption and bribery was implicated.  The direct consequence of this incident is that community owners have sold their houses at low prices.  Except for the thirty-odd multi-story buildings in the first phase that have been built, almost all other houses in the community are in unfinished condition. Construction equipment on construction sites can be seen everywhere in the community.  This is also the reason why no residents watched such a big case happen in the community.

    Building No. 5, where the murder occurred, is a six-story brick-concrete building facing south and facing north. This building also happens to be one of the most dangerous row of buildings in the community.  Five meters to the south of the building is a sloping mountain covered with trees. There is only a symbolic barbed wire fence between the residential building and the mountain, which does not provide any protection at all.  The location where the body was located was the east door on the second floor of this building.

    After the five of us were dressed neatly, we walked into the cordon.

    There is a certain order in the investigation of the crime scene.  First, I, the trace inspector, entered the room to process fingerprints, shoe prints and other traces throughout the scene to prevent subsequent technicians from inadvertently damaging the crime scene.

    As a criminal photographer, Fat Lei has to follow me with a camera to assist me in extracting key physical evidence.  In this digital age, imaging photos taken by SLR cameras have become an indispensable part of trace inspection.

    ¡°When I finish my investigation, Brother Ming will go inside to examine the body.  After the autopsy examination at the crime scene is completed, Lao Xian will extract the biological materials that need analysis and testing from the crime scene and return them to the laboratory for testing.  Of course, all inspection processes require Pang Lei to assist with the camera.

    In just a few breaths, we each stood in front of the crime scene with our investigation tools.  Fat Lei was quickly assembling the camera equipment, and Brother Ming and Ye Qian naturally stepped aside to make a space for me.

    I took a look at the door facing north. It was made of iron security door, with a cross-shaped lock cylinder, and the color was dark red.  This kind of door is also called an engineering door. It is an extremely cheap door collectively equipped by developers. The main structure of this kind of door is actually a layer of cardboard sandwiched between two layers of iron. A person with strong strength can kick it.  You can just kick him away. The standard method is to guard against gentlemen but not against villains.

    I took out a piece of micro trace collection equipment from the inspection box.  This equipment consists of two parts, a camera device as thin as a wire and an image collection instrument. Its main function is to collect trace evidence that cannot be found with the naked eye at the crime scene. In this case, it is to observe whether the door lock has been broken.

    After debugging the equipment, I aimed the camera at the keyhole.  With several clicks of the shutter, the internal structure of the lock cylinder was photographed onto the memory card built into the instrument.

    After doing all this, I took out a few bottles of powder and started collecting fingerprints on the door.  This kind of door is the most common object. For me, the entire collection process does not take more than ten minutes.

    Just when Fat Lei had just finished assembling the camera, I put away the brush that collected fingerprints and turned around to take a look. I saw Fat Lei gently press the shutter button a few times, then raised his right hand and made a gesture to me.  With an "ok" gesture, I pushed the door open and walked into the crime scene.

    The room where the crime occurred is a one-bedroom-one-living structure, with a visual area of ??no more than 70 square meters. There is a living room on the right side of the door, in which a set of sofas and a set of home stereos are placed.  On the left side of the door is the dining room and kitchen. Through a transparent glass sliding door, you can clearly see that the kitchen has serious signs of turning.  On the south side of the living room are the bedrooms, bathroom and storage room from east to west.  According to the reporter's description, the deceased was in this bedroom.

    I squatted down and tapped the wooden floor with my fingers several times, but there was no obvious sound from the ground.

    "Laminate flooring." I quickly identified the object I had to deal with when I entered the room.

    Generally, laminate flooring is wet-pasted during the decoration process. The process is to first lay a layer of cement floor indoors, then lay the floor grooves, and finally lay the wooden floor on it.The surface is considered complete.  The laid wooden floors are close to the ground with no gaps in between, so there is not much sound when knocked.

    But if it is a solid wood floor, it is completely the opposite, because during the laying process of the solid wood floor, a layer of "keel" will be laid first, and then the wooden floor will be placed on the "keel", which means that there is a space between the solid wood floor and the ground.  , during the tapping process, a "dong-dong" echo will be emitted.

    Determining the material of the ground plays a vital role in extracting on-site footprints.

    Take laminate flooring as an example. Since most of this kind of flooring uses industrial glue to squeeze wood chips together, this kind of flooring has strong hardness and smoothness, and shoes can leave clear shoe prints when you step on it.  .  For the shoe prints on this object, I only need to use the footprint light to clearly observe them.

    The difficulty of solid wood flooring is higher, because its surface has uneven texture, and sometimes only part of the sole pattern can be left when stepping on the shoes. For such a floor, I have to look for a large number of shoe prints indoors.  Shoe print photos are cut and spliced ??to create a complete sole pattern.

    Fortunately, the ground at the scene is the kind of object that can be observed directly, which makes me breathe a sigh of relief.

    But when I turned on the footprint light and started searching the ground, the scene in front of me seemed to tell me: "Small, are you happy too soon?"

    The reason why I was surprised was because there was a kind of shoe print in the room that I didn't expect.

    I squatted on the ground and carefully moved to the shoe print.  The entire shoe print is composed of several depressed dot-like marks arranged vertically. I frowned and carefully observed these seemingly irregular white dot-like depressions in front of me.

    Fat Lei saw my frown and walked up to me: "What's the matter, Xiaolong?"

    "Brother Lei, I just asked before entering the door. I have basically eliminated all shoe prints of unrelated persons. From the current point of view, this shoe print should be left by the suspect." I pointed to the ground.

    "What kind of shoe print is this?" Pang Lei also stared at the ground with curiosity.

    "If I guess correctly, these should be spikes."

    "Spike shoes? Spikes for running? Is the suspect an athlete?" Fat Lei was a little pleased.

    I shook my head: "Not all athletes wear spikes. There are many types of spikes circulating in our market, and there are four types that I know of."

    "Four kinds?"

    "Yes! The first type is the well-known track and field spikes, mainly worn by people who participate in running, high jump and long jump; the second type is football spikes, which is easy to understand; the third type is called golf spikes, because when playing golf  During the ball, swinging the club requires force, so golfers who often play golf also like to wear spikes. The fourth type of spikes is also a more common type of spikes, called fishing spikes. Some fishing enthusiasts will wear spikes if they catch big fish in the river.  , which requires the grip of the sole of the foot to provide support, this type of spiked shoes is also commonly available on the market.¡±

    Fat Lei nodded while listening: "It turns out there are so many types. I thought I could use it to judge some characteristics of the suspect."

    I sighed helplessly: "Not only will it not narrow the scope of suspects, but it will also increase the difficulty of analysis."

    "Oh? What should I say?"

    "From the shoe prints at the scene, it is not difficult to see that the spikes worn by the suspects have very hard spikes on the soles, otherwise they would not have scratched the hard laminate flooring indoors. The only thing we can analyze now is this  Several rows of irregular dotted marks cannot analyze the suspect¡¯s height, height, weight, or thickness from the shoe prints, so it has no value at all.¡±

    Fat Lei looked at my disappointed expression and patted my shoulder: "Don't worry about it. Let's deal with other traces first. In case the suspect committed the crime without wearing gloves, wouldn't it be more targeted to find fingerprints?"

    I had no choice but to stand up and walk towards the kitchen, which was being disturbed quite a lot.  (Remember the website address: www.hlnovel.com
