Chapter 19: The Scene of the Fire
Tang Xiujie, the director of the funeral home in Ningzhou City, was suspected of helping a criminal gang illegally burn the body, and at this critical moment, Tang Xiujie was burned to death in his villa home by a fire.
It's ironic that he often helped others burn corpses, and now he himself died in fire.
In the bedroom was a double bed with a charred corpse facing up.
Although this house belonged to Tang Xiujie, it was not certain that the deceased must be Tang Xiujie based on a corpse alone. Moreover, the hair, skin, facial features, primary sexual characteristics and other features of this corpse that can be preliminarily identified were all burned with this fire, leaving only the charred muscles exposed on the surface of the body.
However, there are many ways for professional criminal police and forensic doctors to identify the deceased.
The water used to fight the fire was mixed with the fine impurities on the ground, which was very muddy, and also damaged the fingerprints and footprints that might have been left at the scene. Everyone had a clear division of labor and immediately began to investigate the cause of the fire and the subtle traces that may have been left at the scene.
"Judging from the current situation, it is very likely that this bedroom was the point of fire." Jiang Tingbai looked at the appearance of the room, walked to the window again, and carefully inspected it.
The glass of the window has been burst, and the window frame has been deformed by the heat. This is the most common type of double glazing, which is strong and warm. Jiang Tingbai carefully observed the remaining glass fragments on the windowsill, there were almost none in the room, and all of them were outside.
This shows that the windows were not vandalized, especially from the outside in, and that the windows were closed from the inside at the time of the fire.
Because in a closed room, the high temperature generated by the flame will cause the air pressure in the room to increase rapidly in a short period of time, and the strong air pressure crushes the window glass, and the air flow generated by the strong pressure pushes all the glass shards produced out of the window, so no glass shards are found in the room.
And this can also prove that the fire started in this bedroom.
The fire was in the bedroom, Tang Xiujie was also in the bedroom, he didn't run, he didn't struggle and shout when the fire started, he let himself be burned to death by the fire, I absolutely don't believe it.
He must have died before the fire appeared, just like the deceased in the Zhu family's murder house.
But it cannot be ruled out that he fell into a coma because of a certain situation and did not escape.
Because the fire produces a large amount of smoke and toxic gases such as carbon monoxide, if a large amount of toxic gas is inhaled in the first place, it will cause carbon monoxide poisoning.
It is likely that the deceased inhaled a large amount of smoke in his sleep and was incapacitated until he was engulfed in flames.
"The deceased was burned by the fire and took on a 'fist fighting pose.'" Zeng Lan observed the situation of the corpse and said seriously.
Forensic doctor Ren Qiushi stood beside her and nodded affirmatively.
In half a month, the internship period of forensic doctor Zeng Lan will end, and she can theoretically become a regular, but whether she chooses to stay in the Ningzhou Public Security Bureau is up to her to decide, she can go to other public security bureaus, or she can return to school to continue her academic studies.
The two put on gloves and prepared to perform a preliminary autopsy on the deceased here.
"It looks like he was killed by fire." After Ren Qiushi finished speaking, he looked at Zeng Lan, he decided to let Zeng Lan complete the autopsy independently this time, and he would make auxiliary supplements and records on the side.
Zeng Lan calmed down and took this autopsy more seriously, she said slowly: "Because the flexor muscles of the human body are stronger than the extensor muscles, the cremation of the corpse after death can also form a fist fighting posture, and the specific cause of death should be autopsied to see if there is a large amount of smoke in the mouth, trachea and lungs of the deceased, so as to determine the cause of death." ”
These are the most basic theoretical knowledge of forensics, Ren Qiushi was expressionless, and he didn't say anything.
Zeng Lan carefully examined the surface muscles of the deceased and said seriously: "The musculogenetic and skin tissues of the deceased have been completely charred, the muscle tissues have spasmodic and strong contractions, and the scars on the body surface have completely disappeared, which makes it very difficult to judge whether the deceased was violated before his death. ”
Ren Qiushi and Zeng Lan worked together to lift the body and let it lie on its side.
We found that in the position under the deceased, the sheets and mattresses burned the lightest, or even did not burn at all.
"The musculature of the deceased's back is also relatively intact, and the burns are the least severe compared to other parts of the body." Zeng Lan said.
"What does this mean?" Ren Qiushi's face was expressionless, and he asked Zeng Lan seriously.
"This shows that at the time of the fire, the deceased had been lying in bed, not running away for shelter, or even motionless. At the same time, it also shows that the location under the deceased was not the point of fire. Zeng Lan replied seriously.
The medical examiner performs an autopsy on the body, and what we need to do is to investigate the fire scene and determine the point of the fire and the cause of the fire.
In an indoor fire like this, the direction of the fire is still easy to judge, as long as it is obvious according to the severity of the burning. Similarly, the location of the fire can be determined based on the course of the fire.
As for the cause of the fire, if arson is excluded, any aging wire, non-standard use of electrical appliances, and unextinguished cigarette butts may cause a fire.
There are two fire points in the murder case of the Zhu family's murder house, one is a battery car fire, and the other is a small sun heater fire.
"Old dog, have you found anything?" I asked Jiang Tingbai.
"I didn't smell any accelerant." He shook his head.
The so-called accelerant is a substance that cannot burn by itself, but can expand the fire, such as alcohol, gasoline, etc., these accelerants do not leave traces, but they will leave a distinct odor.
It is known that the fire started in this bedroom, but the cause of the fire is not yet clear.
There was no sign of the deceased fleeing or struggling.
It can basically be judged that with an obvious homicide case, the murderer burned the scene after the killing, creating the false impression that the deceased died accidentally.
The fire broke out at four o'clock this morning, and the time of death is not far away, and the results of the autopsy are still awaited.
We went house by house to inspect the site, and we surveyed the second floor and all the rooms in the villa.
Finally, we reached the rooftop of the villa through the second floor.
With the experience of the Zhu family's murderous house, we investigated the rooftop very carefully, and the murderer was likely to flee the scene through the rooftop after killing and setting fire.
There was a thick layer of dust on the rooftop, the dust was intact, there were no footprints and other traces, it seemed that no one had been here for a long time, and the murderer had not come here either.
And we found that the valuables in the villa were not lost, and the murderer was not trying to make money, which made me even more convinced that Tang Xiujie's death was the murder of the criminal gang behind him.
The purpose is also very simple, that is, to cover up the truth that he helped cremate the body......
