Liu Shuyuan looked at Bai Song and felt inexplicably depressed.
Once upon a time, they were classmates sitting together in school. Although they did not know each other in school, they had the same starting point. It should be said that his starting point was higher.
The last time they went to Shonan Province to handle a case together, although he felt there was a gap, he felt that he had made considerable progress in recent days.
He also participated in a lot of work this time, but in less than 24 hours, the Jiuhe Branch solved the case?
What about growing up together?
…
"First of all, I think Wang Fanfan died accidentally. Her death has nothing to do with anyone, not even Lin Mingfei or Li Yanan. However, it was her death that led to the subsequent events." Before Bai Song could finish his words, someone interrupted him immediately.
"How could it be an accident? Although Wang Fanfan is not tall, he is much taller than the depth of the pool." The speaker was the captain of the Xingang District Public Security Criminal Investigation Brigade: "Besides, the water pipe is not old, it must have been damaged by human beings."
"There is no point in destroying the water pipe. Besides, all the investigations have not found any evidence of man-made damage to the water pipe." Bai Song still has a strong aura. Standing here with so many leaders, the local detachment leader cannot bring him too much pressure. "In physics, there is a famous phenomenon called the 'water hammer effect'."
Seeing that everyone was frowning, Bai Song explained, “It sounds complicated, but it’s just the basic Newton’s first law, the law of inertia.
The law of inertia has another name, called the law of inertia, which means that objects are very reluctant to change their state of motion unless they are subjected to other forces.
The water hammer effect is the inertia of water. If the inside of a water pipe is very smooth and the water flows freely, when an open valve is suddenly closed, the fast-flowing water inside will generate a huge pressure on the valve.
Because the inner wall of the pipe is smooth and the water flows smoothly, all the energy of the water carrying a large amount of kinetic energy is concentrated near the valve. This situation is called positive water hammer.
In addition, the sudden opening of a closed valve will cause negative water hammer, which has relatively little destructive force.
Wang Fanfan came down alone to fill the swimming pool. When the water was about to fill up, she simply turned off the valve. Then, due to the 'water hammer effect', the water pipe suddenly burst, and a large amount of water flowed directly onto her head, spraying her and making her a little dizzy. Then she fell into the swimming pool, and because of the temporary confusion, she drowned and died.
"I support this point of view." No one spoke, and Hao Zhenyu spoke.
Many people present here know Hao Zhenyu. As an expert in on-site investigation, his words show that Bai Song's inference is consistent with the on-site investigation results. A bunch of people who wanted to question it suddenly stopped talking.
Wang Liang was secretly laughing in the background, and he felt secretly happy when he saw the expressions of these people.
For other things, everyone present may be experienced, but when it comes to physics and chemistry, I have to say that everyone present is...
The sense of substitution is too strong... Wang Liang is a little self-indulgent...
"Captain Bai, please continue." Director Wei did not comment and continued.
"From the traces at the scene and the occupancy status of each room, it can be seen that the three female anchors all have rooms here, Li Yanan also has her own room, but Guan Shanyue does not have her own room.
In other words, Guan Shanyue came uninvited.
However, Li Yanan's favorite Liu Shushu did not come, which shows a problem. These three female anchors were not necessarily invited by Li Yanan. Even if he was stupid, he couldn't invite three people at once. Wouldn't it be better to invite them one by one?
Therefore, the only explanation is that these three people got the clues and wanted to come here on their own, and they are all competitors.
Judging from the current situation, this matter is not that simple. These three women are not fools. They are all after money. There is no need to say much about Lin Mingfei. She might be the one who ruined Li Yanan's good deeds.
In other words, Li Yanan came here originally to find Liu Shushu, but was intercepted by Lin Mingfei.
Li Yanan will definitely be unhappy with Lin Mingfei. Zheng Xiaowu and Wang Fanfan are also aware of this situation.
Zheng Xiaowu is older, but not stupid. All she wants is money, and she may be more direct. Wang Fanfan is a silly girl. She came here just to pick up Li Yanan and make her a girlfriend.
They had a quarrel among themselves, and no one else knew about it, but Guan Shanyue knew about it. Guan Shanyue was always asking around about this and that, and was very smart, so he knew a lot of things.
Guan Shanyue came here for money.
He wanted to steal money.
He wouldn't dare to steal at other times, but he dared to do so at this time. The reason is very simple. Li Yanan is a well-known financial director of a law firm. If he really lost tens of thousands of yuan when he went out on a date with a female anchor, would he call the police?
Of course not.
Zheng Xiaowu also knew about this. After Zheng Xiaowu followed Wang Fanfan and Lin Mingfei here, he returned to his residence first.
Zheng Xiaowu thought more directly. He got some ether through some unknown means and wanted to use it to make Li Yanan unconscious. He would just take the money and Li Yanan would have no choice but to swallow her anger.
However, things did not go as they thought at all.
Wang Fanfan went to the swimming pool alone to fill it with water, hoping to swim together or something, but he died unexpectedly below and no one knew about it.
When Lin Mingfei discovered there was a problem in the basement, she was shocked. She might have gone down to check it out, or she might not have. In any case, she chose to close the sluice gate.
The main sluice gate was made of metal and required a lot of force to close. The sluice gate happened to be in the outdoor tool room, so she found a hammer with a thin handle and wanted to use it as a lever to close the sluice gate. As a result, she was seen by Li Yanan at this time.
Li Yanan saw Lin Mingfei holding a hammer to close the sluice gate, and discovered that Wang Fanfan was drowned in the basement, so she thought it was Lin Mingfei who did it.
He himself was somewhat disgusted with Lin Mingfei, and when he saw this scene, he thought that Lin Mingfei wanted to kill and rob, because Li Yanan had a lot of cash in her bag.
He didn't believe that Wang Fanfan died in an accident.
After Lin Mingfei returned to the house, the first thing she did was to go to the kitchen of the villa to wash her hands. Li Yanan, who was already frightened at the time, picked up a hammer and hit Lin Mingfei with one blow, killing her.
He was actually a very timid person. He must have hit her with the hammer on impulse, and as a result, someone died, and he was terrified.
Later, Li Yanan must have run away and didn’t dare to call the police. After a day or two, he came back secretly and threw Lin Mingfei to the ground. Then, the day before yesterday, he felt unsafe and tried to throw Lin Mingfei into the sea.
