Seeing that everyone had a puzzled expression on their faces, Ling Xu pondered for a moment, and then explained to everyone: "It seems that everyone still has doubts about the bruises on the deceased's body. Pen, fun, and www.biquge.info

Although the body temperature of the deceased has dropped, the limbs of the corpse are not completely stiff, and the knuckles can still move with the external force, all kinds of indications indicate that the deceased should have just died.

Corpse spots do not appear on the corpse until two hours after the human death, and at this time there are no corpse spots on the corpse, which means that she has not died for more than two hours, but corpse spots are not the only special phenomenon that appears on corpses.

In addition to corpse spots, bruises on the human body do not appear immediately on the surface of the body, and it takes a while for the bruises to become apparent, which is a little later than the appearance of corpse spots, usually taking three to five hours.

As a simple example, if you examine a person's body immediately after being beaten, there will be no abnormalities on the surface of the person's body at that time, but after a few hours, bruises of various shapes will appear on the part of the person who was beaten.

It has only been about half an hour since Shao Xiaona's death, and even if she had been beaten before her death, it is impossible for the bruises on her body to appear so quickly, at least not in front of the corpse spots.

I had thought that the wounds were there before the deceased's death, but after some inquest, I rejected that judgment, and you can take a closer look and see that the skin around the deceased's bruises was very smooth, and there were no signs of swelling or slight depression.

After the human body is hit by an external force, the skin at the hit site will rupture and damage the capillaries under the impact of a strong external force, and the subcutaneous tissue will bleed, and the blood will seep from the capillary rupture to the subcutaneous, so that the skin surface will be bruised.

After the bruise appeared, the skin around the bruise changed slightly due to the impact of external force and subcutaneous bruising, but the skin on the corpse was all smooth and flat, and there was nothing abnormal in the epidermis around the trace, even the skin at the bruise location did not change, so it can be seen that this was not a bruise caused by an external blow. ”

"If this isn't a bruise, then what are these patches of purple marks?" Lu Liang still didn't believe Ling Xu's analysis.

"It's a disease." Ling Xu said affirmatively.

"Sick?" Lu Liang and Feng Jikui looked at each other, and asked with a puzzled expression, "What disease?" ”

"Thrombocytodeficiency, which is often referred to as anemia." When Ling Xu said this, he looked at the two doctors beside him, and said lightly: "Anemia refers to a common clinical symptom in the human body where the volume of red blood cells decreases, which is lower than the lower limit of the normal range.

Anemia has many complications such as dizziness, tinnitus, headache, insomnia, dreaminess, memory loss, difficulty concentrating, etc., in addition to these symptoms, anemia has one of the biggest characteristics, it can make the skin of the patient's body become abnormally pale.

The reason for this is that when anemia occurs, the body redistributes the effective blood volume in the body through neurohumoral regulation, reducing the blood supply to the patient's organs and mucous membranes, and the color of the patient's body skin will become lighter due to the decrease in the content of red blood cells and hemoglobin per unit volume of blood.

If an anemia patient dies at the onset of the disease, the platelets in her body will clot, normal human platelets are flowing and evenly distributed in the body, but anemia patients have abnormal platelets, so they will coagulate into pieces, and when the patient dies and the blood stops flowing, the clotted platelets will appear under the epidermis and look like bruises.

The deceased Shao Xiaona was slightly darker in complexion, so the abnormality of skin color was not too obvious, but as long as a knowledgeable person observed the soles of the deceased's feet, he would find clues that the surface of the deceased's feet to the ankles were all full of purple marks, but the soles of the deceased's feet were white and blue.

Anemia patients because of the scarcity of platelets, so that the blood supply to the internal organs is insufficient, blood flow is slow, in this case, the patient will have dizziness, fatigue, and cold hands and feet, Shao Xiaona's soles are pale and bloodless, and the soles of the feet are blue, which means that the blood in the soles of her feet is not smooth, and she is cold all year round, which is precisely the most important symptom of anemia. ”

After finishing speaking, Ling Xu looked at the two doctors: "Is what I said right?" ”

Hearing Ling Xu's analysis, the two doctors were shocked and stunned, and were stunned for a moment, and one of the older doctors nodded with admiration on his face: "Is this gentleman also a doctor?" Your description is very accurate, although I don't know how to examine corpses, I have seen a patient with anemia die in a clinical case.

After the death of the patient, his family changed the deceased's shroud from the hospital bed, and I accidentally glanced at the person's body, and found that the body was covered with purple marks, except for the white and dark blue of the feet, which was exactly the same as the situation of this corpse. ”

After listening to the doctor's words, Lu Liang and the others were immediately relieved, and everyone glanced at Ling Xu with surprised expressions, and while admiring in their hearts, they also secretly guessed Ling Xu's identity in their hearts: "Which department is this Mr. Ling?" How can you be so good at autopsies? He can't be a medical examiner, right? ”

Ignoring the thoughts in everyone's hearts, and making sure that the deceased had not been beaten before his death, Ling Xu began to inspect this dormitory, which was an ordinary double police dormitory, with two wooden beds, a desk, four chairs, two kettles, a filing cabinet, a pair of radiators, and some legal provisions and systems nailed to the wall, but there was nothing but these.

The location of this dormitory is in the north of the police station, and the window happens to be facing the small vegetable garden in the backyard, Ling Xu first checked the window, there is nothing suspicious, and then squatted down and looked at the radiator located under the window, and there is no suspicion, no debris left by the rope near the window and radiator, and there is no trace of wiping.

After standing up, Ling Xu opened the window and looked at the vegetable garden and toilet in the backyard, since the dormitory was located on the second floor, his line of sight was relatively far, and he saw that the vegetable garden was divided into small vegetable patches, and different vegetables were planted in each vegetable patch.

In the middle of the garden, there is a brick path leading to the corner of the courtyard wall, where the toilet is located. Outside the courtyard wall, there is a dense forest, because the courtyard wall of the police station is not too high, only about two meters, so that the branches of many trees have grown into the courtyard wall.

After observing for a while, Ling Xu suddenly asked, "Since the deceased was hanging from a tree branch in the backyard, then she has to leave the office building, Director Feng, have you seen the deceased leave the office building this evening?" (To be continued.) )
