    Two hours later, two highly charred corpses were placed on two autopsy beds.

    The skin of the deceased had formed a hard and brittle shell due to the high temperature. Ming Ge took out the scalpel without hesitation and cut along the abdomen of one of the corpses.

    Click, click.  Along with the sound of skin exploding, a disgusting visceral smell hit his face.  The human tissue of the deceased had been roasted until it was half-cooked, and the blood that could have flowed everywhere was like jelly, swaying from side to side as Ming Ge's lancet fell into the body.

    "Guoxian, draw blood." Brother Ming made a small opening in the heart of the deceased and said to Lao Xian who was standing aside.

    Blood testing is the most accurate way to characterize a fire scene.

    We know that carbonaceous substances will produce carbon monoxide during the incomplete combustion process. The site is a firewood house. From the burning residue, it can be judged that there was a lot of firewood in the house when the fire broke out, so when they burn, they can produce a large amount of carbon monoxide.

    The affinity between carbon monoxide and hemoglobin in the human body is hundreds of times higher than the affinity between oxygen and hemoglobin, so carbon monoxide easily combines with hemoglobin to form carboxyhemoglobin, which causes hemoglobin to lose its ability to carry oxygen, causing tissue suffocation, and ultimately death from poisoning.

    Generally, corpses at fire scenes can be divided into two situations: first, the corpse was burned after being killed; second, the person was not dead before the fire.

    Let¡¯s look at the first situation. Before the corpse is burned, the person is already dead. After stopping breathing, carbon monoxide cannot enter the body, so carboxyhemoglobin will not be detected in his blood.

    Having said that, the second situation is quite easy to understand.  The results of this inspection will provide an important basis for the characterization of the site.

    Of course this was not the first time Lao Xian had experienced this kind of thing. He quickly took out a slender glass tube and inserted it into the small hole cut by Brother Ming. Under the action of atmospheric pressure, the bright red blood was quickly  squeezed into the glass tube.

    Just when Lao Xian was loading the inspection materials into the special inspection box, Brother Ming discovered something unusual.  He frowned and pointed the scalpel at the wrist of the deceased.

    Wow!  Brother Ming slashed the knife, and the human tissue of the deceased's wrist was quickly cut open.

    Normally, autopsies do not slit the wrists of the deceased. My attention was attracted by his unusual move.

    ¡°Xiaolong, give me your magnifying glass.¡±

    I didn¡¯t dare to delay after hearing this, and quickly handed the magnifying glass to Brother Ming¡¯s hand.

    He took it without raising his head and observed the incision carefully.  After observing the deceased's left hand, he cut open the deceased's right hand, and finally even the deceased's feet were cut open.

    "Homicide!" Brother Ming put down the magnifying glass and said these two words.

    ¡°Homicide?¡± All of us present took a breath of air-conditioning.

    "I examined the body first because she had some instinctive reaction."

    "What's the instinctive reaction?" Ye Qian glanced at the corpse curiously.

    "If you recall carefully, did the body appear curled up at the scene?"

    "Yes! They are curled up together!" Pang Lei opened the photo in the camera.

    Brother Ming nodded: "We all know that there are two situations for corpses at fire scenes: the first is to be burned; the second is to be burned to death."

    "Let's first talk about some on-site manifestations of the deceased being burned to death. Because the person is not dead at this time, the person who was burned to death will generally have signs of escape and struggle process based on the state of the body, such as the position of the body.  In the corner, under the table, under the bed, or crawling to the door, under the window, or in the stairwell with a protective posture holding the head; and due to the struggle of the deceased, the whole body may be burned, so the clothes and clothing where the body is in contact with the ground  Burn marks will also be left on the skin. Even if the deceased was in a coma before death, there will still be an instinctive struggle reaction during the burning process, and the curled up shape of this corpse is the best explanation of the struggle reaction."

    "Does it mean she was still alive when she was burned to death?"

    "Although Guoxian's test results have not yet come out, I can make a rough guess through the autopsy. There was soot and charcoal powder entering the mouth and respiratory tract of the burned corpse, especially the bronchi and alveoli. It was due to the deceased inhaling carbon monoxide before death.  , the blood, internal organs and body spots of the corpse are all cherry red. For corpses burned after death, soot may be found in the mouth, but there is no soot in the trachea and bronchi, and the mucosa is pale, without congestion or edema.  So I can also judge based on thisIt turned out that the female body was burned to death.  "

    "Then how do you determine it's a homicide?" I still don't understand.

    "Look at the position of the limbs of this corpse."

    At Brother Ming¡¯s prompt, we all looked over.

    He pointed to the human tissue inside the incision of the deceased and said to us: "We can't see anything abnormal from the outside, but after incision, you will find that the outside of the body's limbs are severely burned, and some tissues have been severely charred, but only one  The burns on the circle of human tissue were not very serious, and the tissue in this circle was evenly distributed, so I concluded that her limbs must have been tied before. When burning, the binding acted as a layer of protection, allowing this layer to  The tissue was not burned that badly. This is why the deceased was in a curled up position, because her hands and feet were restrained, otherwise according to human instinct, it should be an escape reaction."

    "Both corpses have their hands and feet tied up?" I curiously glanced at the other corpse that had not been dissected.

    "There is no need to dissect that body, because he was already dead before the fire!" Ming Ge took a look and said.

    "What!" We were a little surprised.

    "Jiao Lei, look at the original photo of the corpse!"

    Hearing this, Fat Lei turned on his camera and rummaged around carefully. Finally, a corpse in the shape of a "big" character, lying peacefully on the ground, appeared in front of our eyes.

    "From the photos taken by Jiao Lei, we can easily see that the body showed no signs of escape, and there were no burn marks on the skin where the body touched the ground. This shows that the body had no signs of life before the fire.  Although I haven¡¯t dissected it yet, my judgment will not be wrong.¡±

    "When I first saw these two corpses, I still had a little fantasy. It was possible that two people had an argument indoors, one of them killed the other, and then the murderer set himself on fire. But looking at it now, it's definitely not the case.  It's the same thing. One person was killed beforehand, and the other person's hands and feet were tied up. So there is a third person present, and that person is the murderer!"

    Brother Ming¡¯s last words were like an uppercut punch to our hearts.

    "The scene was destroyed like this, and there is no clue. How should we start?" This was my first reaction.  (Remember the website address: www.hlnovel.com
