"Before electric cars came out, bicycles were quite expensive. Car thieves only stole bicycles. Later, electric cars were put on the market in batches, and the price of bicycles suddenly dropped a lot...I mean ordinary models, not racing cars."

"Nowadays, you can buy an old bicycle in good overall condition for just a few dozen yuan at the second-hand market. The auxiliary police officer in our station, Mr. Liu, just bought one last month. It's a women's bike, a 26 "Flying Pigeon" with a slash. I bought it for 60 yuan. I adjusted the steel rims and added some engine oil. Now it's very convenient to ride to and from get off work."

"Liao Cunxue spent more than 3,000 yuan to buy that "Beyond". If you don't know how to ride a bicycle, you will definitely fall when you practice. Even if he doesn't feel sorry for his wife, he still has to feel sorry for the money! The new car has been broken a few times, and the shell is broken.

He said, "The parts inside are definitely damaged. Even if you take it to a car shop for repairs, you may be able to buy a new one just by repairing the car."

"I've also seen people learn to practice by themselves after sweeping shared bicycles on the street. That method is cheaper, one or two yuan each time, and it doesn't matter even if they fall. Just do it like this until you learn it. Equivalent to cost

It’s probably less than ten yuan.”

Tan Tao listened and nodded frequently: "Yes! In addition to shared bicycles, there are also shared electric vehicles. Even if you don't know how to ride a bicycle and need to practice, you can practice with that one first! It's much more cost-effective."

Zhou Changhao also agrees: "You can buy old electric cars at the flea market. The roadside stalls in Yingshuiqiao are full of people after eight o'clock in the evening. They cost 300 to 500 yuan a car. They are a bit old.

, it looks ugly and has all kinds of minor problems, but at least it can be ridden."

"As the boss said just now, wouldn't it be nice to buy an old car and come back to practice?"

"If you spend 3,500 yuan to buy a new car, this Liao Cunxue either has a brain problem or a problem with his thinking."

Hu Pingtao was very satisfied that the three people's thinking patterns had entered into the same rhythm. He threw away the cigarette butts in his hands and issued the order.

"I estimate that this case will not be too difficult to investigate. But some work still needs to be done. In this way, the old rule is, if you encounter problems, check the surveillance first. Lao Zhou, there are many surveillance cameras set up around the Wetland Park. You are responsible for checking the relevant times.

Surveillance video in the section. Gong Xinxia’s clothing is of obvious color, so it shouldn’t be difficult to find.”

Zhou Changhao nodded and agreed: "Okay, I will make arrangements after the meeting is over later."

Hu Pingtao said: "I will take people to the park management office now and ask them to search around the crime scene. The target is Gong Xinxia's "Beyond" brand electric car. This is an important evidence and cannot be lost."

Tan Tao quickly stood up from his chair and asked, "What about me? Boss, what do I do?"

"You stay here." Hu Pingtao explained with a smile: "We can't spend all our energy on this case. Someone has to do something, especially at the 110 command center. If there is a situation at any time, we have to do it at any time.

Handle it. You are responsible for taking charge of the overall situation these days and don't make any mistakes."

…

The Wetland Park is located within the jurisdiction of the Eryuan Road Police Station.

Human lives are at stake, so the Park Management Office takes this very seriously and dispatches more than 30 employees to assist Hu Pingtao in searching for the missing electric car.

First, I searched along the shore and found nothing.

Next, we rowed a boat and entered the lake area to search.

Fortunately, the weather was clear, and through the clear lake water which was not too deep, one could basically see the blurry scenery at the bottom of the lake.

The search begins where the body was found.

Nearly three hours later, the electric car was found at the bottom of the lake on the other side of the incident.

Very conspicuous silver gray color, beautiful streamlined shell——Liao Cunxue did not lie, the car was indeed newly purchased.

Hu Pingtao and others immediately inspected the electric vehicle.

The car's switch was activated, which indicated that it had indeed accidentally fallen into the water while driving.

The shell on the left side of the car body has been dented, and there are obvious impact marks. After searching and comparing, scratches matching the same were found on the hard ground on the shore on one side of the salvaged electric car.

The sinking point was found.

The director of the Park Management Office is named Tang Wenming.

He was very interested in this case. On the one hand, it was related to his jurisdiction and responsibilities, and on the other hand, he was curious. As a man, he was very interested in the cases that happened around him, especially the corpse floating in the lake, and the deceased was a woman.

.

Tang Wenming stayed with Hu Pingtao and participated in the whole process.

Looking at the electric car placed on the hard road and comparing it with the scratches, Meng Hui took a close-up shot of it with a camera. Tang Wenming raised his head and glanced at the other side, and asked in confusion: "Director Tiger, the body is clearly visible

It was found on the opposite side, how could you find the car here?"

Hu Pingtao explained: "After the human body falls into the water, it cannot breathe in the water, but more and more carbon dioxide in the body strongly stimulates the nerve center to require breathing, and this process will be very painful."

"At the beginning of this painful process, people take the initiative to bear it. Because the drowning person is still conscious at this time and knows that he is in the water and cannot breathe. But as the oxygen is depleted, the body's instinct to breathe is far greater than the individual's consciousness.

Control, the body will involuntarily breathe, open the mouth and nose and close it, so a large amount of water pours in and pours into the respiratory tract, causing the symptoms of choking and coughing in the lungs."

Tang Wenming nodded repeatedly when he heard this: "What's next, is he drowned?"

Hu Pingtao said: "Yes. As the body becomes further deprived of oxygen, many organs stop working. At this time, even the heart stops beating, and the person who fell into the water has no pain at all, but the brain and body touch are still there, and the body can feel light and light.

…”

Tang Wenming quickly interrupted and asked doubtfully: "Normal people should not have this feeling between life and death! That...how do you know?"

Hu Pingtao explained with a smile: "Experiments in this area have been done many times at home and abroad, and they were described by people who have experienced drowning. If someone pulls a hand at this time, fishes the person out of the water, and performs first aid on the spot, then

It is possible for suspended body organs to recover again. But if it cannot be saved, then there is nothing that can be done."

"To put it simply, a person who drowns has a large amount of water entering the lungs, causing the alveoli to swell and burst, and water enters the blood, causing changes in blood concentration. This eventually leads to systemic metabolic disorders, and the life system cannot operate in a balanced manner, leading to death."

"After a person drowns, if he has not received special training, he will suffocate to death in six to seven minutes. Generally speaking, it takes three to seven days for the body to float. But if the water is relatively shallow and there are no whirlpools, it can take several hours

It can also float."

"This is the case for Gong Xinxia. There is no doubt that this is her first landing point."

As he spoke, Hu Pingtao turned around and pointed to the stone-paved trail behind: "She should have been practicing riding here at the time. Because of improper control, she and the car rushed down. Falling off the bike is not a joke.

Playing with it will cause a short-term fright, and the brain's thinking will also have a short-term interruption effect due to the collision. Especially in the water.

, a brief blank mind caused a misjudgment. She must have choked on a lot of water at that time, and desperately wanted to put her upper body out of the water to breathe. But in that situation, Gong Xinxia was too nervous, and she struggled desperately, maybe a certain part of her body

...For example, her thigh was pressed by the electric car, which caused her to drown in a state of panic."

"It was night when the crime occurred, and there were almost no people in the area. Even if she shouted for help, no one heard her. So she sank. After a few hours, the body slowly floated up and floated on the water."

Tang Wenming suddenly realized: "So we found her electric car at the bottom of the lake here?"

Hu Pingtao chuckled and nodded: "That should be the case."

There must be some unclear points in this explanation, and Hu Pingtao is unwilling to reveal all the details. After all, Tang Wenming is not a policeman, but is only temporarily participating as a facilitator.

As long as his curiosity is satisfied to some extent, it will be enough to decide that the case is an accident.

It would take some time to take photos for the certificate. Hu Pingtao walked on the hard trail and stood on a high place to look into the distance.

This is a gentle slope, with a bridge on the south side across the lake.

The greening of the park is very good: Ginkgo, Phoebe, camphor, osmanthus and other trees are planted into different plant communities. Under the trees are low shrubs, scattered ground cover with lawns, and red salver

, leek and purple duckweed, a colorful pattern made up of.

There is also a tropical plant area to the west, where you can see towering coconut trees and large expanses of lush Canary seaweed.

Hu Pingtao looked at it for a while and suddenly discovered a problem.

He turned around and called Tang Wenming, frowned and asked, "Director Tang, why does it seem like there are no street lights in your park?"

Dispatched on all night patrol missions, Hu Pingtao is very sensitive to public lighting facilities.

Tang Wenming felt strange when he heard it: "Yes! How could there be no? There must be street lights! Director Hu, your words make no sense. We are a public place here, a free and open park, and we must have lighting facilities."

ah!"

Hu Pingtao looked puzzled and pointed to the nearby scenic road: "Director Tang, look over there. There is a streetlight at the corner. From there, to our side, the straight-line distance is at least two hundred meters.

, until the bridge foundation over there is the second street light."

"I have learned about municipal lighting facilities. Generally speaking, the spacing between street lights is mainly determined by factors such as the nature of the road, the power of the street lights, and the height of the street lights. Under normal circumstances, the spacing between street lights on urban roads is within 2

About fifteen to fifty meters. If it is a landscape light inside a community, the distance is forty to fifty meters. If the light source is not very bright, the distance will be further reduced, to twenty meters or even fifteen meters.

"

Tang Wenming hurriedly explained: "Director Hu, the one you are talking about is a street lamp, and I know the installation standards. But this is a park, and it is an open park with no charge. So in addition to the large, high upright street lamps we have here,

There are also landscape lights installed at low locations.”

As he said that, he took Hu Pingtao to the green belt opposite. On the side of a large laurel tree, Hu Pingtao saw a solar garden light inserted into the soil and exposed to a height of about one meter above the ground.

Tang Wenming pointed to the garden lights and said: "Park trails are different from highways. The lighting style we choose here must consider the characteristics of the landscape, be simple and elegant, and have bright colors, and we must also consider cost issues."

"This kind of solar lawn lamp is of good design. It absorbs energy during the day and is enough for lighting at night. There are more than two hundred such solar lamps in our park. If you don't see it, it doesn't mean there is nothing. Haha, just follow the park

If you walk more trails, you will find that there are quite a lot of them.”

Hu Pingtao narrowed his eyes slightly and fell into deep thought.

What Tang Wenming said is reasonable and well-founded.

Indeed, parks are different from roads and it is impossible to install too many lighting lights. Due to financial considerations, solar lawn lights are the best choice.

The lighting effect of this kind of lamp is not very good, the light is hazy, and you have to walk close to see it. Coupled with the special setting of the park's green landscape, the lighting area is limited to a fixed range even within a diameter of thirty meters.

"...It's too dark." Hu Pingtao shook his head slowly.

As soon as this thought emerged from the depths of his mind, he immediately thought of another question.

At this time, Tang Wenming said to himself with confusion on his face: "This area is still very spacious, and there is a small square next to it. That... Director Hu, I don't understand, you said it's dark at night
