Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 700: Ruling out the possibility of accidental death
After the human body is poisoned by carbon monoxide, there will be discomfort symptoms such as nausea and vomiting.

Severe carbon monoxide poisoning can cause a person to gradually lose consciousness and eventually die from suffocation.

The surface features of corpses that died of carbon monoxide poisoning are very obvious.

The blood vessel patterns on the skin surface are clear and linear, and appear dark red.

The mucosal tissue in the nasal cavity will appear delicate pink.

Examining a corpse poisoned by carbon monoxide is the first lesson for forensic doctors and technical detectives.

In other words, any criminal police officer can basically recognize carbon monoxide as the characteristic of a dead body after poisoning.

After Lu Chuan put on his gloves, he stepped forward to inspect the two corpses, opened his eyelids, and opened his mouth to confirm the state inside.

Just a few moments later, it was basically confirmed that the two deceased people had indeed died of carbon monoxide poisoning.

Police officers from the police station to maintain order have set up a cordon around the area.

There are many leaders of the municipal bureau living in the community, and they all learned the news one after another.

"It's hard to say. It should be possible."

When Lu Chuan came to pick up Shen Yan in the morning, he called her.

Zhang Hui thought for a while and then said: "Do you think it was homicide or an accident?"

Lu Chuan did not give a definite answer.

After all, it is the entrance to the Family Courtyard of the Municipal Public Security Bureau.

Just because a person dies does not necessarily constitute a criminal case.

"Lu Chuan, you're saying that you saw someone in this car last night, and then you realized something was wrong when you found someone else in the car this morning, right?"

There are fewer people in the community here to watch the fun.

Deputy Director Shen also learned that Lu Chuan found two bodies at the gate of the community.

It is very likely that the airtightness of the vehicle chassis was not good, causing exhaust gas to enter the car. The two people were not aware of it, and eventually carbon monoxide poisoning occurred.

Is it the police or a family member?

But the woman who died in the car lived in this community, moved from outside, and was not a family member.

"When I came to pick up Shen Yan this morning, I found someone else in the car, and I felt something was wrong."

Especially since the two deceased people were in the car and died of carbon monoxide poisoning at night.

Therefore, the leader is most concerned about the identity of the deceased.

Lu Chuan nodded.

"Shen Yan and I both worked overtime for a while last night. When we came back, it was about 10 o'clock in the evening and there were people in the car."

Fortunately, neither man is a police officer.

The two victims were quickly identified.

Zhang Hui asked.

After checking the body just now, Lu Chuan went around the car to investigate and inspect the vehicle.

The vehicle driven by the deceased was old and the air tightness was definitely not good. As Zhang Hui said, if there was an exhaust leak, it would be possible for the two of them to fall into coma and then die accidentally from carbon monoxide poisoning.

However, over the years, cases of carbon monoxide poisoning have become less common than in previous years.

In the past few years, the conditions for economic and social development have been poor, and private cars have not been fully popularized.

The general public mostly travels by bus or long-distance coach.

When long-distance buses are in operation, especially in winter, the doors and windows will be covered with plastic sheets and other windproof materials to keep warm.

The chassis of long-distance buses in those years had poor airtightness, and vehicle exhaust would enter the cabin. However, the airtightness of the cabin was very good and could not be discharged, often causing collective carbon monoxide poisoning.

But relatively speaking, there have been very few cases of carbon monoxide poisoning in private cars in recent years.

"Check the surveillance."

Zhang Hui also feels that it cannot be determined whether the deceased died accidentally or was killed simply by relying on the cause of death and the place of death. "Brother Hui, arrange another group of people to understand the situation with the family members."

When Lu Chuan was inspecting the body just now, he found a condom in the jacket pocket of the deceased male.

When Lu Chuan just confirmed the identities of the two people, he discovered that the relationship between the two deceased people did not seem to be that simple.

Meeting in a car on the side of the road in the middle of the night, and then both dying, doesn't look like a normal phenomenon.

When the action team sent people to investigate, Lu Chuan was not idle either.

The vehicle was carefully inspected on his side.

Lu Chuan carefully recalled what he saw last night.

When he drove into the community, the car was parked on the side of the road.

Because the temperature had been relatively low these two days, Lu Chuan saw that the exhaust gas emitted from the car was very heavy.

In other words, when Lu Chuan came to the community last night, the car should have been started.

But when Lu Chuan came over to take a look this morning, the vehicle was already out.

If the cause of death of the two deceased persons was accidental poisoning by carbon monoxide.

Then the source of carbon monoxide should be caused by vehicle exhaust entering the car.

Carbon monoxide poisoning can cause the victim to be unaware of the death process.

That is to say, people who are poisoned by carbon monoxide are actually very difficult to save themselves to a certain extent, because during the poisoning process, the initial reaction is very mild.

By the time there is a major reaction, the person will have already lost consciousness.

In other words, even if the brain has the idea of ​​​​saving itself, it is difficult for the body to respond effectively due to lack of oxygen.

In the past, we often saw people who died of carbon monoxide poisoning dying at the last step of opening the door. This is the reason.

Therefore, the reason why the vehicle started up last night and turned off this morning is unlikely to be the driver's own initiative to turn it off.

Instead, the fuel burned out and the vehicle had to be shut down.

So what Lu Chuan wanted to check was whether there was any fuel in the vehicle's fuel tank.

If not, it means the vehicle has burned out of fuel.

In other words, the vehicle has been started since last night.

This is consistent with the external logic that two people died of accidental carbon monoxide poisoning.

But if the fuel in the vehicle had not been burned out, it is possible that the two deaths were not just an accident.

The reason is that if two people die from carbon monoxide poisoning produced by burning car exhaust.

So, after the two people died, there was still fuel in the car, so who turned off the car?
The method of the experiment was also very simple. Lu Chuan unscrewed the key door and started the vehicle directly.

Click click click...

The roaring sound of the motor is thin and long.

Although the two bodies had been moved away, Lu Chuan still did not sit directly in the driver's seat. Instead, he hung his butt in the air, with his left foot outside the car, and his right foot stepped into the car, stepped on the brake, and started the car.

It seems to be a cold start and the vehicle seems to be difficult to start...

but!

boom!
It seemed that at the moment when the battery was about to run out, the vehicle's engine roared.

Lu Chuan looked up at the dashboard.

The fuel indicator shows that there is still half of the fuel in the tank!

There is still so much fuel in the tank, which means that the vehicle's combustion is not natural.

The death of the two people could not be an accident.
