In the afternoon, the Qingcheng Police Department Office.
Captain Yang stood in front of everyone, looked at the file in his hand, and said solemnly.
"We have investigated the identity of the deceased."
"The name of the deceased: Han Xiaoxiao, age: 21 years old! Currently a junior at Qingcheng University."
"She has another identity...the daughter of Han Pingfeng, the chairman of Haifeng Group!"
hiss--
After hearing the identity of the deceased, everyone frowned.
This identity... is tricky!
Haifeng Group is one of the top 50 companies in the country. Hundreds of billions of profits are made every year!
As the daughter of the chairman, Han Xiaoxiao's position is very noble.
But it is such a girl, but today, it is a pity that she is dying.
Captain Yang continued,
According to our investigation, Han Xiaoxiao suffered from a certain degree of depression since she broke up with her ex-boyfriend during his lifetime.

Bai Yan rubbed his chin, took Captain Yang’s words, and analyzed,
A person suffering from depression, jumping off a building to commit suicide is not an incredible act. Therefore, the reason why criminals don’t use other methods to kill Han Xiaoxiao, Perhaps it was just to make us think that Han Xiaoxiao's death was just a simple suicide!"
Captain Yang nodded, agreeing with Bai Yan's point of view.
"By the way, Detective Bai, have you got the surveillance of the mall?" Captain Yang asked.
"I got it. It's just..." Said this, Bai Yan also had a pain on his face, "It's just that the top layer of surveillance broke down a few days ago, so we can't be sure that the criminals are specific. who is it."
When the surveillance on the 15th floor is broken, the police can't know who other than the deceased has been on the rooftop.
Naturally, it is impossible to pursue the murderer in time.
As for the monitoring of the 14th floor, to identify the specific murderer.
Cough...
This is more difficult.
On the 15th floor of the commercial building, there is a high-end western restaurant. There were hundreds of people in the traffic this morning alone.
If you go to investigate one by one.
Even if the entire police force of their police station was deployed, it would take at least ten and a half months.
By then, I am afraid the criminals will have escaped long ago!
"By the way, Detective Bai, did you find anything on the rooftop of the building?" Captain Yang asked.
"Half a footprint." Bai Yan spit out these words gently. "However, with only half a footprint, the information we can know is still limited."
"Is there no way to locate the murderer?" Captain Yang had expectation in his eyes.
Bai Yan shook his head with a wry smile, "No. At least not for a short time."
"Then..." Captain Yang took out his cell phone, "We can only ask for foreign aid!"
…………
Four p.m.
The top roof of the commercial building where the crime occurred.
Cheng Nuo followed Captain Yang and Bai Yan to this place reluctantly.
"Captain Yang, I'm not as godly as you think? There are no clues, so let me find criminals for you? Are you embarrassing me?" Cheng Nuo grumbled as he walked.
Originally, Cheng Nuo, who had just finished inviting guests and earned enough affection between Mu Leng and Su Xiaoxiao, just wanted to send the two women home. Unexpectedly, Captain Yang called.
After asking that Cheng Nuo was around the commercial building, let Cheng Nuo stay where he was. He and Bai Yan would arrive immediately.
Thus, Cheng Nuo, who was confused, was led to the rooftop by two big men.
Looking at Captain Yang and Bai Yan, there was a feeling of a big bad wolf looking at a little white rabbit in his eyes.
Cheng Nuo felt a little flustered.
He subconsciously covered his chest.
There is no one on the left and right on the roof, so every day should not be allowed, and the ground is not working.
These two guys are not going to...
However, things didn't go as Cheng Nuo expected...Ah, yeah, it was going in an undesired direction.
Captain Yang and Bai Yan took Cheng Nuo to a location not far from the high platform on the rooftop.
There was a half-footprint that was fairly clear.
Bai Yan pointed at the footprint, "Hey. This is the clue."
"Next, Cheng Nuo, it's your turn to perform." Bai Yan shrugged.
Cheng Nuo looked down at the only clue that the murderer remained at the scene, his footprints, rubbing his chin, and pondering, "It should be 43 yards."
Bai Yan rolled his eyes, "Of course I know this."
If Bai Yan can't even figure this out, then Bai Yan shouldn't be a police detective here. Just go home and farm.
But the problem is that those customers who came to the 15th floor in the surveillance camera did not have Cheng Nuo's accurate data ability. It was difficult for Bai Yan to judge who had 43 size shoes.
Cheng Nuo continued, "The foot length corresponding to size 43 is 26.5 cm. According to the standard height calculation formula, height (cm) = foot print length (cm) x 6.876, that is, the height of the murderer is 182.29 cm."
Bai Yan shook his head, "I naturally know what you said. However, it is too contingent to calculate height by foot length. A person with a size of nineteen meters and ninety meters may only have a shoe size of 40. And a six-meter six. For those who arrive, the shoe size is likely to be 44 or 45."
"So, the height calculated by footprints can only be used as auxiliary data to find the murderer. It cannot be used as the main data..."
What Bai Yan said was correct.
Errors in height calculated with footprints are always unavoidable.
If by any chance the wrong criminals were targeted, it would really be a waste of all previous efforts.
"Don't worry, I haven't finished speaking yet." Cheng Nuo gave Bai Yan a gesture of peace and quiet, staring at the footprint on the ground.
Then he raised his head and glanced at the distance between the footprints and the edge of the roof, and the height of the fence around the roof. In my mind, various data are constantly calculating and reasoning.
If I remember correctly ~EbookFREE.me~ the position where the deceased fell from the building is at this footstep, facing the direction of the guardrail directly in front, and the position after linear translation more than ten meters.
The color of the toe of the footprint is lighter, and the color of the heel is darker. This shows that when the murderer left this footprint, his body was in a state of extreme exertion. If I guess right, the murderer must have left this footprint here when he pushed the dead downstairs.
The height of the roof guardrail is 1.24 meters. The weight of the deceased was 51.24 kg. Before falling down the building, the deceased obtained a horizontal initial velocity of 3.85/meter per second.
The distance between the footprints and the edge of the roof is 0.54 meters. According to the location of the footprints, it can be inferred that the murderer pushed the deceased downstairs by...
Cheng Nuo used all the known data in his mind to construct a model.
Then, simulate the force that the murderer used when he pushed the deceased downstairs, the position where he was standing, the appropriate position, the method of force, and the best height and weight of the murderer in accordance with the force method. Wait……
With this responsible data calculation. Cheng Nuo has managed to do it, simply...back in time!
