    Ye Qian's doubts were dispelled, and Lao Xian continued: "Demodex folliculorum locked the time of dumping the body within 7 days, and then I tested the 'bleached mother skin' characteristics of the corpse. Finally, the accurate time of dumping the body was determined again.  One day shortened.¡±

    The "bleached mother's skin" mentioned by Lao Xian is an object of interdisciplinary research, and forensic medicine, trace examination, and physics and chemistry have all conducted in-depth research on it.

    Anyone who has studied junior high school biology knows that our skin is composed of the epidermis and dermis. The epidermis is covered with sweat pores. During the metabolism process, the human body will discharge a large amount of oil through the sweat pores, and the oil will form on the surface of the skin.  Grease layer.  When the oil layer disappears under the action of water, the skin begins to absorb water like crazy.

    The epidermis and dermis are not completely attached to each other. Only part of the connective tissue of the former is adhered to the dermis. When the epidermis absorbs water, the unadhered areas will bulge, so from the appearance, the skin will look like wrinkles.  Uneven.  In ancient times, there was a profession called "washerwoman", also known as "washer woman", which refers to women who make a living by doing laundry for others.  Those who have their hands soaked in water for a long time often have wrinkles on their fingers, so this finger phenomenon is also called the "bleached skin" feature.

    The palms and toes are the areas with the thickest epidermis on the body, and are prone to the characteristic of ¡°bleached skin¡±, but this does not mean that this characteristic only occurs in the hands and feet.  In fact, as long as the skin is soaked in water for a period of time, "bleached skin" will be formed.

    Once "bleached skin" is formed, if the skin continues to be immersed in water, the connective tissue between the skin layers will be burst under the tension of the water, causing the dermis and epidermis to completely fall off, resulting in peeling.

    Under similar external conditions, the water absorption speed of human skin is very similar.  Hundreds of floating corpses can be found in the Sishui River every year. We have recorded data on "floating female skins" of different genders, different age groups, and different body shapes.  When it is impossible to judge the time of falling into the water through the characteristics of the corpse, comparing the data of "bleached mother skin" becomes the only shortcut.

    It was determined that the total time the body fell into the water was 6 days. Referring to the real-time flow rate table of the Sishui River issued by the Maritime Safety Administration, Mingge set the location of the body within 200 to 250 kilometers upstream of Xiyan Pier.  Although the inferred range is as far as 50 kilometers, there are actually not many stone bridges with no guardrails and uneven bridge decks.

    The suspect's body was dropped by a heavy object. The body can be washed away by the undercurrent of the river, but the heavy object will not. We only need to screen out the stone bridges that meet the requirements and let the salvage team dive into the river bottom to see if there are any fallen objects.  corpse place.  (Remember the website address: www.hlnovel.com
