In the past, Bai Song was not able to participate in forensic discussions. He was more of an investigator and looked at the conclusions directly. This time, he had the opportunity to sit at the conference table.
Director Ma did not participate in this case, but out of trust in Bai Song, he agreed to it. In the end, Bai Song joined the Jiuhe Branch's support team for the special project.
He is no longer the same as before and is highly valued by the leaders. Moreover, when Bai Song's name was reported to the Municipal Bureau's list, several leaders seemed to know this young man.
…
Group 4 will definitely be back on track in the next shift. Bai Song, Ren Xu and Mi Feifei have all given some instructions, so there is nothing to worry about. Bai Song asked Mi Feifei to take care of the newly retired cadre first.
After Bai Song left, the person who felt the most pressure was Ren Xu. However, people will grow very slowly without pressure. Thinking of this, Bai Song nodded with satisfaction.
…
By the evening of that day, the scene had been cleaned and sealed, and the body had been taken away for more detailed autopsy and physical and chemical tests. A group of leaders and forensic doctors were sitting here discussing the case analysis.
"I would like to apply for an investigative experiment." After many forensic doctors expressed their ideas, Qin Wushuang made his own statement.
Carbon monoxide poisoning, that's not a problem.
However, there is currently controversy as to whether the cause of death was carbon monoxide poisoning.
First of all, unless someone uses carbon monoxide tanks or other means to introduce large amounts of carbon monoxide into the house, the source of the carbon monoxide must be the incomplete combustion of liquefied petroleum gas.
The charcoal powder found in the burnt pot is currently believed to be the result of the long-term baking of the dumpling soup, which turned it into black powder.
The deceased died in the bedroom. He may have died of poisoning after eating half of his meal, or he may not have a big appetite and only ate half of it.
No relevant toxins were found in these foods.
After all, the bedroom is some distance away from the kitchen. Although the doors and windows of the house are closed in winter, can the carbon monoxide produced by an ordinary liquefied gas stove due to incomplete combustion reach a lethal level in the bedroom?
This will be much easier if you come a few days in advance.
The reason why carbon monoxide can cause poisoning and death is mainly because carbon monoxide has a strong ability to bind to hemoglobin, which can produce carboxyhemoglobin and reduce the blood's ability to transport oxygen. Generally, when the binding rate exceeds 40%, people are in danger.
Of course, this does not mean that the room needs to contain 40% carbon monoxide. Even if the concentration is not high, it will still accumulate in the body if inhaled multiple times.
The standard for judging the inhaled concentration is very simple, just look at the concentration of carbon monoxide hemoglobin in the blood.
Moreover, people who die from this reason will develop cherry-red corpse spots.
However, the premise of all this is that the death has not occurred for long.
Zheng Xiaowu has already shown a state of gigantism. The livor mortis has long disappeared, and the proteins in his body, including carboxyhemoglobin, have already begun to decompose in large quantities. It would definitely be inaccurate to measure the concentration now.
"Investigation experiment?" The leader of the municipal bureau hesitated for a moment and said, "There's no rush for this."
Only serious and major cases can apply for investigative experiments. It is an investigative measure that refers to the various conditions at the time of the crime and recreates the facts or phenomena.
To put it simply, we simulate the previous situation and see what specific carbon monoxide concentration can be produced in this room under the premise of being sealed and maintaining exactly the same state.
However, in investigative experiments, any behavior that could cause danger should be prohibited. If the liquefied gas tank is lit in this way, carbon monoxide will be produced. If it explodes, no one can take the responsibility, so the leader directly rejected it.
After all, no one can control the explosion limit of carbon monoxide. Just because it didn't explode before doesn't mean it won't explode during the experiment.
Captain Qin nodded, understanding the concerns involved, and did not apply to the director again.
"Does anyone have any other ideas?" the leading director asked. "Regarding the cause of death, if there is no conclusion yet, we will wait for the detailed autopsy. Before that, don't be afraid of making mistakes and speak freely."
After this was said, many criminal police officers who were not forensic doctors also proposed some possibilities, which were also recorded in the meeting minutes. Of course, most of them were obviously impossible and were ruled out by the forensic doctors.
"I want to ask," Bai Song discovered a detail that many forensic doctors overlooked: "Why is there some rotten lump soup in the mouth and esophagus of the deceased?"
"Everyone knows this," Sun Jie said directly, "This is also related to the time of death of the deceased. For a corpse in this state, it is normal for the gas in the body to ferment and push out the contents of the stomach. Similarly, some things will be pushed out from the exit."
"Okay, I learned it." Bai Song didn't want to imagine that scene. It was really a bit disgusting.
…
At present, the situation of the eight people in this company has been grasped. At first I thought there were seven female anchors, but later I found out there were actually two men and five women.
The deceased, Zheng Xiaowu, was from Jiuhe District, Tianhua City. The persons confirmed missing so far are: Lin Mingfei, a native of Shangjing City, who has a well-off family and has conflicts with her parents; and Wang Fanfan, a female, who is currently out of contact.
The above three people live in one house.
In addition, the whereabouts of the boss Dou Jianli is unknown.
It has now been verified that this company actually has two male anchors. One is called Guan Shanyue, who is from Northeast China and is currently on his way. The other one is not a regular anchor, but a doctoral student named Du Zigan who only comes to broadcast live during the winter and summer vacations. Du Zigan sometimes broadcasts live at school or home, occasionally talking about some knowledge-based things, but he hardly gets any rewards. Although the company gives him a basic salary of 1,000 yuan, he is actually the one who loses the most money.
There are two other female anchors who are on their way. Their names are Hua Youyou and Liu Shushu. They are both talent anchors. They live in the same room because they sometimes perform dancing, so they need a larger space.
After retrieving some of the company's account flows, it was found that the company's financial situation is not good. The basic salary of each anchor is only between 1,000 yuan and 3,000 yuan, and the reward money, in addition to the platform's money and taxes, is split 50-50 between the anchor and the company. There is no such thing as five insurances and one fund.
Everyone who was supposed to come had arrived, and then the tasks were assigned. Bai Song and others were responsible for questioning the doctoral student named Du Zigan.
According to these people, there are two other men in the company who occasionally come to help. They are mainly responsible for computer matters. These two men are also responsible for connecting with the platform. Sometimes they can buy some promotions, etc. The current situation has not been fully understood.
