"Ms. Jiang, I'm sorry."

Zhao Lecheng, whose wish to seek advice was not met, was entrusted with an important task to prevent Ms. Jiang from disrupting the on-site investigation and inquiring about her son's recent situation.

It is indeed an important task. No matter which one is, it can make the newbies beat the ground in an instant.

The workplace people are not the best, but everything is for the sake of the iron rice bowl. Zhao Lecheng secretly encouraged himself and walked up with a tough bullet.

Lao Zuo followed Zhou Nan with his laptop, "It's really okay to let him go alone?"

Zhou Nan walked back to the body again, "Where is there anyone? Isn't there so many team members to help?"

Lao Zuo, "...". Is this what he asked?

No matter how many people assist and dominate, it is still the little newbie.

It's normal to think about it again. It's not that easy to take on the title of their elder apprentice. It's just a "simple" inquiry record, and it's normal to hone the operation.

Only Zhou knew what the actual situation was.

The two returned to the "placement point" issue mentioned just now on the rooftop.

"Suicides rarely choose to jump back down, so they are mostly prone positions. Except for serious injuries that are rare on the head, there is no other problem in this point, but this distance..."

Lao Zuo looked at the roof again and estimated the distance between the exterior wall of the experimental building and the corpse. "In theory, if you jump down by yourself, the height of the seven-story building will be calculated according to the eighth floor. The landing point will not exceed two meters from the wall."

He handles such a building fall incident every year without ten or eight. His experience is abundant, so he can easily determine the problem.

Zhou Nan nodded, "But now the body fell on the outer edge of the four-meter-wide green belt, and suicide was indeed a bit unreasonable."

Unlike Lao Zuo, his basis is not his case handling experience, and he has no experience to verify now.

If you commit suicide, the initial level speed will be small, and the corpse will be close to the building. On the contrary, if it is thrown down, it will be a vertical falling movement, and the distance between the corpse will be relatively far.

It's a very simple truth. Even if you are not proficient in physics, you can make rough inferences based on common sense alone.

Lao Zuo said, "But it is not easy to explain that he killed him. If you fall down from a living building, even if you are pushed down, the maximum landing point should not exceed three meters."

There was no sign of the body being moved.

Weird, weird.

The two looked at each other, and no one could give a reasonable explanation for the time being.

"Boss, left head," Just then, Xiao Zhao covered his arms and grinned and walked back. Several scratches were still quite eye-catching even under the night.

Lucky.

Zhou Nan patted Xiao Zhao on the shoulder, "Thank you for your hard work."

Lao Zuo Hou realized something and expressed a certain degree of sympathy.

"No, no," Xiao Zhao, the person involved, had not noticed anything and was still excited about his ability to complete the task "smoothly".

"Have you asked clearly?"

Nodding, turning on the small notebook, Zhao Lecheng reported on what he asked about.

"The family situation of the deceased is quite complicated. His parents divorced before he was born. In the next five years, Ms. Jiang remarried three times, but they all ended in a miserable state. After that, she devoted herself to her career and raising children, and never considered her personal issues..."

That was quite "unconsidered"... As expected, the narratives from the parties involved had to be given several discounts.

"Tell me the point," Zhou Nan signaled.

Lao Zuo added, "About the deceased."

"Oh," Xiao Zhao quickly turned down when he heard this and continued, "Unlike ordinary rich young men, Qi Chujin is quite excellent as a rich second generation. His academic performance has always been among the best since kindergarten. He has not had the bad hobbies of girls in the bar. It can be said that he has both good character and academic performance."

This...it seems to be just one handsome face that can become the male lead in a romance drama.

"Social relations are simple, what about the situation in school? What about the relationship with classmates?" Lao Zuo had to concreteize the problem. He was afraid that he could continue to listen to it without any limits and imagine an idol drama.

Fortunately, Xiao Zhao is not that hopeless, and all the questions Lao Zuo said are asked.

"According to Ms. Jiang's reaction, Qi Chujin was kind-hearted as a child and never quarrels with classmates, let alone fights and other conflicts. She has never let her have any snacks in the past ten years. Recently, Qi Chujin has not had any abnormality. She should study and study as usual. The club is active and goes home on time. So she feels that her son will definitely not be able to commit suicide."

"I was afraid that she would not say anything comprehensively by herself, so I also consulted the school on this issue. The class instructor and Ms. Jiang said that the situation was similar. The deceased was introverted and had no other special hobbies in daily life. He was a very worry-free and good student. I really couldn't figure out why he jumped off the building."

Speaking of this, Xiao Zhao's face became bitter again. "When the school decided that her son jumped off the building by himself, Ms. Jiang was excited and said it was impossible, and then she pinched her..."

Oh, this is the origin of the arm injury.

Good character and academic performance, simple social relations, and harmonious relationships among classmates. What is the problem?

After the report, Zhao Lecheng seemed to have thought of something again and said excitedly, "Boss, I have figured out the problem you just said!"

Oh? The little newbie is quite sensible?

There were no clear clues left and right, Zhou Nan said with great interest, "Tell me, let me see."

"Is it him killing me, right?"

Without waiting for the two to answer, Zhao Lecheng held up the book and continued to analyze according to his own logic. "This building has seven floors. According to the height of each floor, the roof is about twenty meters away from the ground."

"From the gravity acceleration g=10, the drop time is about 1.414 seconds, so the center of gravity of the corpse should be between 1.5 and 2 meters away from the wall."

"This shows that his horizontal speed is about 1 to 1.4 meters per second. As we all know, fs=1/2mv^2. Even if calculated at the smallest 1 meter per second, the required horizontal force is about 12kg..."

"The landing point at this time is obviously far beyond this distance. It is impossible for suicide to fall from the building to have such a large horizontal force, so there must be a problem with the horizontal force."

Lao Zuo, "!"

I never thought you were Xiao Zhao like this.

As we all know, he is not worthy of this, so he returned all the physics in high school to the teacher decades ago.

The boss really has a unique vision and a wise eye to recognize the beads. No wonder he decided to give guidance on his own just one side. Really, Sherlock Holmes Benfu!

And at this moment, Sherlock Holmes Benfo Zhounan was complaining from the bottom of his heart.

Although the result is well known that there is no need to be such a complicated calculation, such a top student type B is very profound and mysterious. Please make sure to let your brother pretend to be one if you have the chance.

I didn't adjust a little.

In fact, it may not be as complicated as imagined, because we are in modern society, most cases can be solved through the "three magic weapons".

Zhou Nan turned around and asked, "Have you got the elevator surveillance?"
