I want to be a super cop

Chapter 231 Dangerous Takahashi
"The name of the deceased is Wang Feifei. She was a student of Shangnan Foreign Language School, a 16th grade student in the Department of Economics and Management."

Shen Mengxi took out a small wallet from the deceased's pocket: "Their school has been notified, and the school is currently sending the relevant person in charge."

On the student ID card, Faye Wong's ID photo is also very handsome, walking in the school should also be the kind of object of attention.

"foreign language School?"

Zhong Tianzheng murmured, took a breath and looked at Ah Xiang: "Where is the foreign language school?"

"In Songgong District."

"Songgong District?"

Zhong Tianzheng nodded his head, indicating that he knew it, and there was no sound.

The deceased has been transported away, waiting for follow-up autopsy to obtain more detailed information.

The murderer's motive for the crime is currently unknown.

Now what they need to determine is the murderer's modus operandi and location, to see if they can obtain useful information.

"Look around for available clues."

The team leader quickly gave instructions and dispatched the surrounding law enforcement police officers.

Zhong Tianzheng stood where he was, looking directly at the location where the corpse was salvaged, and looked up from time to time.

Above.

It is the towering Xupu Bridge, full of traffic.

About 10 minutes later.

Zhong Tianzheng turned his head to look at the group leader beside him: "Did you find anything?"

"Not yet."

The team leader shook his head and explained: "There are not many surveillance cameras on this section of the road, and there are checkpoints on the sightseeing belt, so cars can't get in at all, but there are no traces of struggle around. From the initial cause of death of the deceased According to the analysis, she was drowned alive, so I doubt whether the murderer threw her directly from the bridge."

"Ah."

Zhong Tianzheng nodded and agreed: "I agree with you very much, because I can be sure that she was thrown from the bridge."

"Ok?"

The team leader's eyes were full of doubts.

"The navigable height from the Xupu Bridge deck to the water surface is about 45 meters. At such a high altitude, this method is undoubtedly the fastest and safest method to kill people."

Zhong Tianzheng quickly stated the basis for his judgment and pointed in the direction of the bridge pier: "The deceased fell into the water closer to the bridge pier. Pay attention to that direction. Are there a few pieces at the bridge pier more than one meter above the water? The remaining water spots?"

"..."

The group leader looked at Zhong Tianzheng speechlessly.

The two are now at least 20 meters away from the bridge pier, how can they see the water spots on it clearly?
but.

Other than that, there seems to be no reasonable explanation.

If the murderer had thrown the man into the water from a river cruise, he would have two big problems.

First: There is a separation belt in the tourist belt, and cars cannot enter. If a living person is brought to the tourist belt, she will definitely resist, and the process is very difficult.

Second: Even if he brought people to the river, according to Shen Mengxi's preliminary judgment, the death time of the deceased Wang Feifei was very short, and the water depth of the river was not very deep to drown people.

The main problem is that.

The location of Wang Feifei's death was more than ten meters away from the shore. If you want to throw people in and drown, you can't use a motorboat, but in Shangnan City, people who own private motorboats are all registered big figures, and Motorboats are under unified management, and the goal is too big.

in this case.

Zhong Tianzheng's statement is the most realistic.

"However, there is no basis for your judgment."

Ah Xiang on the side expressed a different opinion: "In such a high position, dropping a person with an iron ball tied down should cause a huge impact."

"According to the most ideal environment, H=1/2gt^2, we can get T, and based on V=gt, we can get that her falling speed is about 90m/s." Ah Xiang spoke very quickly, feeling in her heart He was quickly doing mental calculations: "With the help of the formula Ft=MV, Feifei Wong's weight plus the five iron balls on her feet must be 200 pounds, right? Assuming that the falling time is two seconds, we can get the approximate impact force Around 4500N."

"Although the calculation by this formula is not accurate, it is enough to show that she had a great impact when she fell. If there is really a splash, the water marks left on the pier are also large and large, not It's so small, isn't it?"

Ah Xiang looked at Zhong Tianzheng with a serious expression, her tone full of impoliteness.

"Ha ha."

Zhong Tianzheng didn't know whether to cry or laugh for a while: "I can only say that Comrade Ah Xiang's previous physics scores were very good, but didn't he stay too much in the books?"

Ah Xiang retorted as a matter of course: "I'm not right?"

"you are right."

Zhong Tianzheng nodded affirmatively, then turned his hand and slapped her forehead with a bang: "But you are not enlightened enough, do you understand what I mean?"

"Ouch."

Ah Xiang couldn't dodge, so she rubbed her slightly aching forehead and complained: "How can you be like this, beating someone when you can't argue? Violently surrender?"

"Didn't your teacher tell you when you were in the police academy that all knowledge should be judged based on the scene, the actual thing, and the reality?" Zhong Tianzheng corrected angrily: "Ah Comrade Xiang, I ask you to consider the reality when calculating. Wang Feifei's legs are being pulled down by heavy objects, and her falling posture should be at a [-]-degree vertical angle to the water surface. Her shoulders are as wide as six. Ten is good, but the actual contact surface when she enters the water is her feet, the contact area is very small, and if it gradually becomes larger, how much splash can it produce?"

"To put it bluntly, the more vertical a diver's entry posture is to the water surface, the smaller the splash will be. Do you understand?"

"..."

Ah Xiang nodded thoughtfully, snorted and simply turned away from Zhong Tianzheng.

Originally, I wanted to show off, but who knew that I was slapped in the face in an instant.

The team leader nodded in agreement, stood on Zhong Tianzheng's side, and added: "Ah Zheng's hypothesis will be reflected in the follow-up detailed autopsy report, so we don't have to worry about it. Go to the bridge and look for any traces the murderer may have left."

The group of people quickly turned to the top of the bridge.

at the same time.

The team leader also asked people to contact the traffic police department as soon as possible, maybe the footage from the camera surveillance.

Xupu Bridge is located on the hanging river, connecting the two jurisdictions on the left and right of Shangnan City, with a total length of about six kilometers.

When the three of them drove up, the fully rising sun covered the A-shaped main tower.

From a distance, the entire bridge is shining with golden light.

As the car drove on the two-way eight-lane bridge, Zhong Tianzheng kept looking at the electronic monitoring equipment on the bridge outside the window.

basically.

As far as the eye can see, almost all of them are covered by the surveillance equipment, so will the surveillance capture anything?

Will it give a great impetus to the detection of the case?
