Chapter 628 Killed in the Chamber of Secrets
Liu Sheng didn't expect that when he came to hand over the corpse, he could witness the change of the Ningtai County Bureau team.

Fortunately, this series of personnel changes seems to have been brewing for a long time. In just one day, the office of the political commissar of the county bureau was replaced by the director, and the familiar deputy director Huang Qiangmin became the political commissar.

Liu Sheng, who had been working as a background board for a day, felt that it had no effect on him. He should eat and drink, bought a ticket and waited to go home.

evening.

In the atmosphere of eating and drinking, Huang Qiangmin sat down next to Liu Sheng.

"Oh, Bureau Huang, congratulations." Liu Sheng put down his chopsticks and said auspicious words first.

"Thank you. I made you laugh. I'm used to staying in Ningtai County..." Huang Qiangmin said casually in the scene, and said a few words, just as usual, "There are a lot of cases in the capital. I'm usually busy. not busy?"

"Busy, how can you not be busy." Speaking of work, Liu Sheng immediately started the infinite complaint mode: "It's one thing to have a lot of work, and the work can't be done at all. You are an old criminal policeman, let's be honest, Some cases really take time to work out. If it is a murder case or a serious case, then take time to work on it. If it is not, then you can only squeeze your time to do it, and you really can’t do it..."

"It should be easier these few years."

"That's for sure. There are fewer contact cases now. When the economy is better, there will be fewer criminal cases..."

"There are more economic cases."

"Haha, it's like this. The scale of our economic investigation is getting bigger and bigger every day. Young people also like to go to economic investigation. White-collar crimes are really good. Unlike our criminal police, who are often bloody... ..."

As a good listener, Huang Qiangmin nodded from time to time, which greatly released Liu Sheng's emotions and made his speech more comfortable.The two sides didn't talk about specific cases, but just talked about it in general, especially about work benefits, bonuses and subsidies, just like white-collar workers.

After drinking a glass of beer, Huang Qiangmin opened another bottle, and asked: "The funding of the Beijing Bureau is very high. I talked to someone before, and I feel that your funding is unlimited."

"It's a lot of expenses. But I don't need to worry about it." Liu Sheng paused for a moment, then smiled and said, "To be honest, for our grassroots departments, the expenses for the past few years are quite comfortable, as long as we can solve the case In terms of funding, it’s still easy to talk about, that’s the ‘as long as’, sometimes it costs people’s lives.”

"Will there be a difficult case?"

"The unsolved cases may be due to various factors, and some are really... hard to say." As a criminal policeman, Liu Sheng still has a very strong self-esteem, especially when facing a case, he is unwilling to say "no". of.

However, there are always cases that cannot be solved, which is a real problem.

Huang Qiangmin poured wine, but did not speak.

Liu Sheng hesitated for a moment, then said: "There are still too many cases, murder cases alone, there are more than 200 cases every year, we are divided into a brigade, and there are no young or old. As long as there are one or two complicated cases in it, it will be very troublesome. "

"The capital city is really the capital city. It's not like us. We have two or three new homicide cases every year, and there are more than three or four." Huang Qiangmin smiled and said, "It's like our Jiang Yuan. I often do small cases."

Liu Sheng was taken aback: "That's such a waste."

"Yes."

Liu Sheng put himself in his place to help find a solution, and said, "You can dig up the backlog, and we are doing the same now. On average, we have to complete several backlogs every month."

"It was done like this before. Recently, I plan to implement a model of 'one case, one file, one responsible leader' to strengthen the cleaning of files and the bottom-up of physical evidence. Strong evidence, collection of physical evidence, and collection of uninspected physical evidence involved in the case may take a certain amount of time, and when the results come out, Jiang Yuan will be called back to handle the case.” Huang Qiangmin has not yet taken office, so he has three hands with his new official The fire is clearly prepared.

He used to be the captain of the criminal police brigade, so he could only take care of his own affairs.Now that he has become the political commissar of the county bureau, he can organize the whole county to complete the work of physical evidence and sort out murder cases.

With such a foundation, I believe that the remaining accumulated cases in Ningtai County can be dealt with to the greatest extent.

Of course, Huang Qiangmin followed the example of the police stations in other places to do this, and it was not just for the backlog of cases in this three-acre land in Ningtai County.Not worth it at all.

He wanted to show it to Qinghe Municipal Bureau, Changyang Municipal Bureau, and even other city and county bureaus inside and outside the province.

I went out with Jiang Yuan to do so many accumulated cases, although most of the time it went smoothly, but I have to admit that there are always too few clues in some cases, so that Jiang Yuan can't complete it alone, so he has to find Liu Jinghui and Xu Taining many times cooperate.Needless to say, this model somewhat reduced Jiang Yuan's own influence.

Therefore, in Huang Qiangmin's view, it is still very necessary to reorganize the cases in various places.

In fact, it was indeed necessary. Liu Sheng even had contact with the corresponding sorting work, so he simply drank beer and discussed it with Huang Qiangmin.

Huang Qiangmin was very happy, drank with him until late, and made an appointment for the next day's itinerary.

This time, Huang Qiangmin is not going to sell Jiang Yuan to Liu Sheng directly.

First of all, it is because Liu Sheng's level is not high enough to decide many things.Secondly, the conditions in the capital are too good and there are too many experts.

Experts are not needed for small cases, but if there is a big case, there is no need for a big case. For almost influential cases, the Beijing Bureau has a lot of manpower to choose from.

Huang Qiangmin felt that Jiang Yuan was very strong, but could he be as strong as a well-known national expert?He wasn't too sure either.

Therefore, taking advantage of this opportunity, Huang Qiangmin dragged Liu Sheng around to visit, and at the same time asked Liu Sheng himself to learn some advanced experience.

The news of Bureau Chai's departure spread quickly.

In the afternoon, two criminal police captains from other counties called and asked about Jiang Yuan and Huang Qiangmin's recent situation.

Now that Chai Tong is gone, no one will pay any attention to him.

Huang Qiangmin still refused firmly.

It wasn't until Yu Wenshu from Changyang City called that Huang Qiangmin had a good talk with him.

As far as the surrounding area of ​​Ningtai is concerned, Changyang City is obviously still the biggest buyer, just look at the people in the special class of Jiangyuan Accumulated Cases.In this era of insufficient police force, there is and only the criminal police team in the provincial capital can spare more manpower.

Of course, the wool comes from the sheep, and Changyang City can borrow people from the prefectures and cities below. It is a white wolf with empty gloves.

Huang Qiangmin still finds it very fragrant.

Long story all night.

Early the next morning.

The members of Jiang Yuan's accumulated case special class gathered together, and after many days, they left for Changyang City with great interest.

Accompanying him were Liu Sheng and his two team members.

Audi A6s starting with white A lined up at the front of the convoy, and the entire convoy almost filled the parking lot of the Criminal Police Detachment of Changyang City.

The various license plate numbers made the passers-by policemen who didn't know the truth amused, and made everyone who knew the truth shudder.

"One case at a time?" Yu Wenshu was also in high spirits. He was used to the fine clothes and good food, and it would be so uncomfortable to return to the harsh and outstanding environment.

Huang Qiangmin nodded solemnly, and then said: "Let's find a real case, first try to get a good start, is there any real case recently?"

"There is one..." Yu Wenshu hesitated for a moment: "The case is still a little complicated, I don't know if it is suitable for a good start."

"Then let Jiang Yuan take a look at it first. If it's suitable, we'll do it. If it's not suitable, we'll talk about it."

"Okay." Yu Wenshu immediately arranged staff.

Seeing the familiar people coming and taking Jiang Yuan and others to the conference room, Huang Qiangmin let out a comfortable breath.This kind of sales method is interesting, unlike going to other provinces, you have to prove yourself first, what's the point of proving, you have to be begged now.

Shang catcher's business, not business.

While thinking this way, Huang Qiangmin looked at Liu Sheng from the corner of his eyes, hoping that this old criminal policeman could use his forensic eyesight in criminal investigation and be more sensible.

……

Jiang Yuan came by car from Ningtai, closing his eyes and resting his mind all the way, thinking about nothing, not caring about anything.

When they went to Changyang City to do a case, they were really too familiar. Inexplicably, Jiang Yuan still had a little bit of expectation.Without any discrimination, criminals in big cities are more likely to use their brains when committing crimes.

For example, in Ningtai County, there was a case of hacking people to death for three yuan of fast food, which would never happen in Beijing, Shanghai or even Changyang City.

Why?Because there is no fast food for three yuan in Changyang City!

Lao Zhou, the captain of the Second Brigade of the Criminal Police Detachment, came with the file, with a liberated smile on his bitter and bitter face.

"Captain Jiang, you are here. This time, we really encountered an interesting case." Lao Zhou looked like a queen, and his face was like that, and the ringing of the beads in his heart could be heard all over the building.

Jiang Yuan smiled politely and said, "Then have a look."

Lao Zhou let out a "hey" and said: "We have taken over this case for four days. The victim is a woman. That morning, a Mercedes-Benz C entered the public parking space outside the community, and there was no movement. The vehicle was found At that time, it was in the activated state. The victim, Yue Ling, was dead. Forensic examination revealed that it was caused by carbon monoxide poisoning."

Mu Zhiyang, who came with him, cheered at the right time, and said, "Didn't the car exhaust kill you?"

"That's right, carbon monoxide poisoning in the car, the first thought was that the exhaust gas caused death. However, we checked the car, the doors, windows and trunk of the car were sealed, there was no trace of picking the lock, and the car had not been illegally modified. It's not a confined space, so there's no way to talk about death from exhaust fumes." Old Zhou paused, and said, "It's also for this reason that this case was changed from abnormal death to murder."

Jiang Yuan nodded slowly, first took out the forensic report to read, and read out the important parts, and also gave an explanation to the team members:
"On-site cadaver surface examination, the body spots are light red, and the ten nail beds are light red, slightly bright. Incontinence. No obvious damage on the body surface."

"The anatomy examination the next day showed that the pectoralis major muscle was pink; bleeding spots were visible on the surface of both lungs; the heart blood was cherry red and did not coagulate. There were no abnormalities in the remaining organs."

"Methamidophos, dichlorvos, dimethoate, parathion, tetramine, barbiturates... and other common poisonous ingredients were not detected in the heart blood."

"The detected carboxyhemoglobin content was 70%."

……

After reading the forensic report, Jiang Yuan couldn't help but nodded, and said, "It's really carbon monoxide poisoning."

Seeing a dead body a pretty pink color is usually carbon monoxide poisoning.This simple way of judging probably originated in Japan, because there is a local habit of burning charcoal to commit suicide.Ordinary people and journalists will come to this conclusion after seeing too many remains of people who committed suicide by burning charcoal.

But for forensics, it is possible for them to encounter simulated carbon monoxide poisoning.

Detecting the content of carboxyhemoglobin, checking the bleeding points in both lungs, checking toxicology, etc., are all to rule out the possibility of simulation.

After all, if the car exhaust did not leak, the most likely scenario would be death from poisoning.

But not.

Jiang Yuan couldn't help looking at Lao Zhou: "Have you found the source of carbon monoxide?"

"Yeah, the secret room killed people." Lao Zhou sighed, and his bitter eyes secretly glanced up at Jiang Yuan.
