In the past, Bai Song was not involved in forensic discussions, he was more of an investigator, directly looking at the conclusions, but this time, he was fortunate to sit at the conference table.

Director Ma did not participate in the case, but out of trust in Bai Song, he still agreed to the matter, and finally Bai Song joined the support team of the Jiuhe Branch to the project.

He is no longer what it used to be, he is quite valued by the leaders, and when Bai Song's name is reported to the list of the city bureau, several leaders seem to know this young man.

...

In the next shift, the four groups will definitely be able to get on the right track, Bai Song, Ren Xu, and Mi Feifei have all made some instructions, but there is nothing to worry about. The newly transferred cadre, Bai Song asked Mi Feifei to take him first.

Bai Song's departure, the most stressful is Ren Xu, but people have no pressure, and their growth will be very slow, thinking of this, Bai Song nodded with satisfaction.

...

In the evening of the same day, the scene had been cleaned up and sealed, and the body was taken away for more detailed autopsy, physical and chemical tests, and the leaders and forensic doctors were sitting here to exchange information on the analysis of the case.

"I'd like to request a reconnaissance experiment. After many forensic doctors finished their thoughts, Qin Wushuang made his own expression.

Carbon monoxide poisoning, that's fine.

But whether the cause of death was carbon monoxide poisoning or not is currently controversial.

First of all, unless someone uses carbon monoxide canisters and other means to feed large amounts of carbon monoxide into the house, the source of carbon monoxide must be the incomplete combustion of liquefied petroleum gas.

The charcoal powder found in the pot that was burned through is currently believed to be a boiled gnocchi soup that has been baked for a long time and then burned to a black powder.

The place of death of the deceased was in the bedroom, and it may have been poisoned to death after eating half of the food, or it may have been a small amount of food, only half of which was eaten.

No toxins were found in these foods.

The bedroom is always far from the kitchen, although the doors and windows of the house are closed in winter, but an ordinary liquefied gas stove, the combustion is not sufficient, the carbon monoxide produced, can the carbon monoxide in the bedroom reach a lethal amount?

This, if you come a few days in advance, is much easier.

The reason why carbon monoxide can poison people to death is that the binding ability of carbon monoxide and hemoglobin is too strong, which can produce carbon monoxide hemoglobin and reduce the ability of blood to transport oxygen.

Of course, it does not mean that you need to have 40% of carbon monoxide in the house, even if the concentration is not high, it will still accumulate in the body if you inhale it many times.

The criterion for judging the inhalation concentration is very simple, just look at the concentration of carbon monoxide hemoglobin in the blood.

Moreover, people who die for this reason will form cherry red corpse spots.

However, the premise of these is that the death time is not long.

Zheng Xiaowu has already shown the state of a giant view, the corpse spots have long been gone, and the proteins in the body, including carbon monoxide hemoglobin, have already begun to decompose in large quantities, and it is definitely not accurate to measure the concentration now.

"Reconnaissance experiment?" A leader of the city bureau led by him muttered: "This is not in a hurry. ”

Investigative experiments, only major cases can be applied. It is an investigative measure to reproduce the facts or phenomena in light of the various conditions at the time of the crime.

To put it simply, simulate the previous situation and see what kind of carbon monoxide concentration can be produced in this room, which is kept in the same state under the premise of being closed.

However, in the case of reconnaissance experiments, all acts that are sufficient to cause danger should be prohibited. In case of an explosion, no one can afford to take this responsibility, so the leader directly refused.

After all, no one can control the explosion limit of carbon monoxide, and it has not been blown up before, so it may not be blown up without doing tests.

The Qin detachment nodded, understanding the scruples in this, and did not apply again without this director.

"Do you have any other ideas?" the head of the bureau asked, "Regarding the cause of death, if there is no conclusion for the time being, we will wait for the specific autopsy, and before that, everyone should not be afraid of mistakes and speak freely." ”

As soon as these words were said, many criminal police officers who were not forensic doctors also raised some possibilities, which were also recorded in the meeting minutes, of course, most of them were obviously impossible, and they were ruled out by the forensic doctor.

"I want to ask", Bai Song found a detail that was ignored by many forensic doctors: "Why are there still some rotten pimple 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, the corpse in this state, the gas in the body ferments, and it is normal to push out the contents of the stomach, and similarly, there will be some things that are pushed out from the exit." ”

"Okay, learned. Bai Song didn't want to imagine that scene, it was really a little disgusting.

...

At present, the situation of all eight people in this company has been mastered. At first, I thought it was seven female anchors, but later I found out that it was actually two men and five women.

The deceased, Zheng Xiaowu, was a native of Jiuhe District, Tianhua City. At present, the person who has been confirmed to be missing is Lin Mingfei, a native of Shangjing City, whose family conditions are good, and who has conflicts with his parents;

The above three people live in one room.

In addition, the whereabouts of the boss Dou gradually are unknown.

Now it has been confirmed that this company actually has two male anchors, one is named Guan Shanyue, a person from the Northeast region, who is currently on his way over. The other one is not a fixed anchor, but a doctoral student who only comes to live broadcast during the winter and summer vacations, Du Ziqian. Du Ziqian sometimes broadcasts live at school or at home, occasionally talks about some intellectual things, and has almost no rewards, although the company will give a basic salary of 1,000 yuan, in fact, he is the one who loses the most money.

There are also two female anchors, who are also on the way here, named Hua Youyou and Liu Shushu, both of whom are talent anchors, and they live in the same room, because sometimes there is a dance, so they need more space.

After obtaining some of the company's accounts, the company's financial status is not good, and the basic salary of each anchor is only 1,000 yuan to 3,000 yuan, and the reward money, in addition to the platform's money and taxes, the anchor and the company are divided into fifty and fifty, and there is no such thing as five insurances and one housing fund.

The people who should come came, and then assigned the task, and Bai Song and the others were responsible for asking this doctoral student named Du Ziqian.

According to these people, there are two other men in the company, who occasionally come over to help, mainly responsible for computer things, and these two people are also responsible for docking with the platform, and sometimes they can buy some promotions, etc., the current situation has not been specifically grasped.
