    When the Public Security Bureau handles cases, it must not only pay attention to evidence, but also follow legal procedures.  Without an inspection certificate, our investigation work does not comply with regulations. In the future, when lawyers raise questions, the evidence collected at the scene will be rejected with one vote. The famous "Offset Simpson case" is a good lesson for the future, so we would rather wait a little longer than we can.  Violation of case handling procedures.

    After several years of training, Ye Qian has transformed from a little girl to a mainstay now. In just half an hour, the photo of the inspection certificate was sent to my WeChat.

    With the legal procedures in place, Brother Ming took our department to Lin Mingxi¡¯s residence.  In order to enter the room, you must first get the lock cylinder, which is not a difficult task for me.  The door uses a super C-level lock cylinder, which is the most difficult to crack on the market. Even with the use of professional tools, it still took me nearly 20 minutes.

    The moment the door was opened, everyone present felt a sense of enlightenment, not because we found any valuable physical evidence, but because the lighting in this apartment was excellent.  The entire house runs north-south, with the door facing north. The entrance is a large living room and dining room without any obstructions. The northwest corner of the room is an open kitchen and bathroom; the southwest corner is a luxurious bedroom; there is a 45-degree slope at the far west of the house.  A corner wooden staircase leads to a deck.  The platform is a standard configuration for each household, about 70 square meters, long from east to west and short from north to south. It has a rectangular structure and is equipped with a small swimming pool and leisure benches.  There is also a nanny's room of about 10 square meters in the southeast corner of the platform.

    Since the doors and windows were closed, the floating dust layer on the ground was not very thick. After completely blocking the room, I found a large number of men's slipper prints.

    Opening the shoe cabinet, I found a total of 3 pairs of slippers for two men and one woman, one of which was made of plastic and the other two pairs were made of high-end leather.  The shoe prints on the ground were left by this pair of men's plastic slippers.

    Lao Xian took out a portable microscope and found blood scabs in the granular grooves of the slippers. This conclusion at least proves that the suspect passed here after the body was dismembered.

    ¡°What is he going to do when he comes back here?¡± With this question in mind, I drew the suspect¡¯s indoor walking route on the site plan.  We refer to it as a.

    After a opened the door with the key, he put on plastic slippers and went straight into the bathroom. Then he walked up the stairs to the nanny's room wearing water-stained slippers.  It is either convenient to enter the bathroom or take a bath.  If it is convenient, it will not leave water-stained shoe marks, so the possibility of bathing is very high.

    Why do you need to take a shower as soon as you enter the door?  There must be dirt on him.  In the process of dismembering the body, a large amount of blood will inevitably be stained on the body. In this case, there is a reasonable explanation for entering the door to take a shower.  What's amazing is that Lao Xian also found dried blood clots in the corner of the bathroom.  The speculation was confirmed again.

    Just when the investigation was coming to an end, I accidentally discovered the "hidden artifact of this copy", which was a mutilated occult blood fingerprint left by the suspect on the drawer frame.

    The main difference between "occult blood fingerprint" and "blood fingerprint" is that the former contains less blood and has lighter lines. Unless there are special methods, it is difficult to find matching features.  What is even more difficult for me is that the occult blood fingerprint I found only occupies 1/4 of the area of ??the fingertip. If I use ordinary methods, this fingerprint has no use value at all.  But nothing is absolute. With the advancement of technology, fingerprint inspection has also ushered in the latest method-sweat pore comparison technology.

    Before introducing ¡°sweat pores¡±, we must first talk about how fingerprints are formed.  The skin of the fingers is composed of epidermis, dermis and subcutaneous connective tissue.  The surface of the connective tissue of the skin is uneven, forming ravines and ridges. When observed under a magnifying glass, concave and convex striped patterns can be seen, which are called fingerprints in trace science.

    Sweat pores are a physiological structure distributed on the surface of the skin, which are the openings of sweat gland ducts.  Most fingerprint sweat glands are distributed on the top of the papillae lines, and each fingerprint contains a large number of sweat pores.  The sweat pores in different parts of the body can be divided into palm sweat pores, orifice sweat pores, limb sweat pores, etc.  Sweat pores have various shapes, such as single holes, parallel holes, and multiple holes; and depending on their sizes, they can be divided into round holes, oval holes, polylateral holes, irregular holes, dumbbell holes, etc.

    Therefore, even if the incomplete fingerprint does not have enough detailed features to refer to, we can still use a high-power microscope to measure the sweat pore characteristics of the fingerprint.  The comparison of "fingerprint sweat pores" requires three steps.

    First, the orientation of the imprint.  We need to determine which hand left the incomplete fingerprint extracted. If possible, it is best to determine the specific finger.

    Second, locate sweat pores.  In this step, it is necessary to select lines with dense distribution of sweat pores to fix the position.

    Third, sweat pore measurement.  Use a high-power microscope to measure the number, location, shape, size, arrangement relationship, etc. of sweat pores on the lines.

      With the above data, the suspect can be identified even with incomplete fingerprints.  (Remember the website address: www.hlnovel.com
