Tiger Police

Chapter 432 Lighting
"Before electric cars came out, bicycles were still quite expensive. People who stole cars only stole bicycles. Later, electric cars were launched in batches, and the price of bicycles 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 tens of dollars in the second-hand goods market. The auxiliary police officer in our office, Old Liu, just bought one last month. Women's car, the 60 "Flying Pigeon" with a slash. I bought it for [-] yuan, adjusted the steel ring, added some engine oil, and now it is very convenient to ride to and from work."

"Liao Cunxue spent more than 3000 yuan on the "Beyond". People who can't ride a bike will definitely have to wrestle. Even if he doesn't love his wife, he has to love the money! The new car fell several times, and the shell broke. , the parts inside must be damaged. Even if it is pushed to the car dealer for repairs, it may come and go again and again, and the money for repairing the car may be enough to buy a new one."

"I've seen people sweep shared bicycles from the street and learn to practice by themselves. That method is cheaper, one or two yuan each time, even if it falls, it's okay. Just do it like this until you learn it. Converted to cost Probably less than ten dollars."

Tan Tao nodded frequently when he heard it beside him: "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 use that to practice first! It will be much more cost-effective in this way."

Zhou Changhao also deeply agrees: "You can buy old electric cars in flea markets. The roadside stalls at Yingshuiqiao are full of people after eight o'clock in the evening. One car costs 500-[-] yuan. The old ones are a bit old. Ugly looking, with all sorts of kinks, but at least it rides."

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

"Spending three thousand five thousand 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 thinking patterns of the three had entered the same pace.He threw away the cigarette butt in his hand and issued an order.

"I guess this case will not be too difficult to investigate. But some work still needs to be done. In this way, the old rules, first check the monitoring when encountering problems. Lao Zhou, there are many surveillance cameras around the Wetland Park, and you are responsible for checking the relevant time slots. Surveillance video inside. Gong Xinxia’s clothes are very colorful, so it shouldn’t be hard to find.”

Zhou Changhao nodded and agreed: "Okay, I'll make arrangements after the meeting."

Hu Pingtao said: "I will take people to the park management office now and ask them to search around the scene of the crime. The target is Gong Xinxia's "Chaochao" 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 am I doing?"

"You stay in the office." Hu Pingtao explained with a smile: "We can't spend all our energy on this case. Someone has to do things, especially the [-] command center. Deal with it. You are in charge of taking care of the overall situation these days, so don’t make any mistakes.”

……

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

Human life is at stake, and the Park Management Office attaches great importance to this, dispatching more than 30 employees to assist Hu Pingtao in finding the missing electric car.

First, I searched along the shore, but found nothing.

Then row a boat and enter the lake area to look for it.

Fortunately, the weather was fine, and through the not-so-deep clear lake, you can basically see the blurred scenery at the bottom of the lake.

Start the search from 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, beautiful streamlined shell --- Liao Cunxue is not lying, the car is indeed newly bought.

Hu Pingtao led the people to check the electric car immediately.

The switch of the car was activated, which indicated that it was indeed accidentally falling into the water while driving.

The shell on the left side of the car body has been dented, with obvious impact marks.After searching and comparing, on the hard ground on the side of the shore where the electric vehicle was salvaged, a scratch that matched it was found.

The sinking point was found.

The director of the park management office is surnamed Tang, named Tang Wenming.

He took the case very seriously.On the one hand, it is because it is related to one's own jurisdiction and responsibilities, and on the other hand, it is because of curiosity.As a man, he is very interested in the cases that happened around him, especially the corpse floating on the lake, and the deceased was a woman.

Tang Wenming has been following Hu Pingtao and participated in the whole process.

Looking at the electric car that was placed on the hard road and compared with the scratches, Meng Hui took a close-up shot of the electric car with a camera.Tang Wenming raised his head and glanced at the opposite bank, and asked in puzzlement, "Director Hu, the body was obviously found on the opposite side, so how did you find the car here?"

Hu Pingtao explained: "After the human body falls into the water, it cannot breathe in the water, but the carbon dioxide in the body is increasing, which strongly stimulates the nerve center to demand breathing. This process will feel very painful."

"At the beginning of this painful process, it was artificially endured. Because the drowning person is still awake at this time, knowing that he is in the water and cannot breathe. But as the oxygen is exhausted, the body's instinct to breathe is far greater than personal consciousness Control, so the body will breathe involuntarily, open the mouth and nose and close, so a lot of water pours in, pours into the respiratory tract, and produces symptoms of lung choking."

Tang Wenming nodded again and again: "The next step is to be drowned?"

Hu Pingtao said: "Yes. As the body is further hypoxic, 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 are still in touch, and the body can feel light. ..."

Tang Wenming quickly interrupted it, and asked suspiciously: "This kind of feeling between life and death, normal people should not have it! 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 are described by those who have experienced drowning. If someone pulls a hand at this time to pick up the person who fell into the water, and after on-site first aid, then The suspended body organs may recover again. But if they cannot be saved, then nothing can be said.”

"To put it simply, a large amount of water enters the lungs of the drowned person, which causes the alveoli to swell and burst, and the water enters the blood, which changes the blood concentration, and finally leads to systemic metabolic disorders. The life system cannot operate in balance, and then dies."

"After drowning, if you don't have special training, you will suffocate to death in six to seven minutes. Generally speaking, the body will float up in three to seven days. But if the water is relatively shallow and there is no whirlpool, it will take a few hours. It can also float."

"Gong Xinxia belongs to this situation. There is no doubt that this is her first sinking point."

As he said that, Hu Pingtao turned around and pointed to the stone-paved trail behind him: "She was supposed to be practicing here at the time, but because of improper control, she rushed down with her and the car. It's not a joke when she fell off the bike. Playing will cause short-term fright, and the brain's thinking will also have a short-term interruption effect with the collision. Especially in the water, the short-term thinking blank caused mistakes in judgment. She must have choked a lot of water at the time, and she was eager to get rid of it. Her upper body came out of the water to breathe. But in that situation, Gong Xinxia was too nervous, she struggled desperately, maybe a certain part of her body... such as her thigh, was pressed by the electric car, which caused her to drown in a state of panic. Death."

"It was nighttime when the incident happened, and there were almost no people in the area. Even if she called for help, no one heard her. So she sank, and 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: "It should be like this."

There must be something unclear in this explanation, and Hu Pingtao is unwilling to expose all the details.After all, Tang Wenming was not a policeman, but only temporarily participated as an assistant.

It was enough just to satisfy his curiosity to some extent and to decide that the case was an accident.

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

It is a gentle slope with a bridge to the south across the lake.

The greening of the park is very good: Ginkgo biloba, Dianrunnan, camphor, osmanthus and other trees are planted into different plant communities.Under the trees are low shrubs, lawns scattered across the ground, and colorful patterns made of red sorrel, chives, and purple commelina.

There is also a tropical plant area in 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 found a problem.

He turned around and called Tang Wenming, frowned and asked, "Director Tang, why don't you seem to have street lights in this park?"

Sending out all night patrols, Hu Pingtao is very sensitive to public lighting facilities.

Tang Wenming felt strange when he heard it: "Yes! How could there be no street lights? There must be street lights! Director Hu, what you said is unreasonable. We are a public place, a free and open park, and there must be lighting facilities what!"

Hu Pingtao showed doubts, and he pointed to the nearby scenic road: "Director Tang, look over there, there is a street light at the corner. From there, to our side, there is at least 200 meters of straight-line distance between the front and back. Until the foundation of the bridge over there is the second street light."

"I have learned about municipal lighting facilities. Generally speaking, the distance between street lamps is mainly determined by factors such as road quality, street lamp power, and street lamp height. Under normal circumstances, the distance between street lamps on urban roads is 25 to about 50 meters. If it is the landscape lights inside the community, the spacing is 50 to 20 meters. If the light source is not very bright, the spacing will be further reduced, 15 meters, or even [-] meters."

Tang Wenming quickly explained: "Director Hu, the one you mentioned is a street lamp, and I know the installation standard. But this is a park, and it is an open park with no fees. So in addition to the large and tall street lamps here, There are also landscape lights installed in low positions."

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

Tang Wenming pointed to the garden lights and said: "Park trails are different from roads. The lighting style we choose here must consider the characteristics of the landscape. It should be simple and elegant, and the color should be bright. And we must also consider the cost."

"This kind of solar lawn lamp is in good shape, and the energy it absorbs during the day is enough for lighting at night. There are more than 200 such solar plug-in lights in our park. If you haven't seen it, Mr. Hu, it doesn't mean that you don't have it. Haha, just follow the trails in the park Walk around more, and you will find that there are quite a lot of them.”

Hu Pingtao narrowed his eyes slightly, lost in thought.

Tang Wenming's remarks are well-founded.

Indeed, parks are different from highways, and it is impossible to set too many lights.For 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 go close to see it.Coupled with the special setting of the park's green landscape, even within a diameter of 30 meters, the lighting area is limited to a fixed range.

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

When this thought came out from the back of his mind, he immediately thought of another question.

But at this time, Tang Wenming said to himself with doubts on the side: "This area is still very spacious, and there is a small square next to it. That... Director Hu, I don't understand. You said that it is dark at night. Yes, she is a woman, how could she come here to practice driving?"

This coincided with the question in Hu Pingtao's mind.

He nodded slightly: "Yes! Although this is a park, it is too far away from the city. Although there are people who come for morning exercises and play during the day, compared with the zoos, green lakes and other parks in the city, the number of tourists here is really small. It’s a lot. At night, there are fewer people playing. Except for the common people who live nearby, I don’t think anyone will come here specially.”

Tang Wenming added: "We only have a park here, and there is no gate. The patrolling security guards get off work at six o'clock. There are only four people on duty at night, mainly guarding the phone in the power distribution station and monitoring room. If there is an emergency It’s better to call the police.”

Hu Pingtao turned to him and asked him, "Do you have surveillance cameras installed here?"

Tang Wenming replied: "It is installed, but the effect is not very good. You also said just now that there are few street lights and the light is dark. Surveillance cameras can only be installed in places with street lights. If someone runs into the green belt to cause damage, then It’s really blind in both eyes, and you can’t see anything.”

Hu Pingtao frowned even tighter than before, and said to himself: "Yes! There is a big square in the north of the park, where the light is much better than here. Why did Gong Xinxia choose to practice here? What is she doing? Hall of Fame?"

Tang Wenming speculated: "Could it be because I don't know how to ride, my skills are not good, and I am afraid that people will see a joke when I fall, so I came to this place with a leeward angle?"

Hu Pingtao nodded: "There is such a possibility."

Having said that, he actually doesn't quite agree with Tang Wenming's point of view—the core of doubt is still the brand new "beyond" heavy-duty electric vehicle.

Three thousand five, this price is too expensive.
