Chapter 409: First clues
“This is hard to understand. The same carp costs 10 yuan a piece in a small restaurant on the street, but if you put this fish in a five-star hotel, how much do you think? Money?”
“The important thing is not the fish, but where the fish is.”
“Su Xiaogang is packing a good family in the fitness club, even if there are some. Average, but the price is still very high.”
“Haven’t you heard that there are two things men love most?”
"The first is to persuade prostitutes to be good."
When Zhang Hui heard this... it made sense: "What about the second thing?"
"Haha, drag the woman from her mother's family into the water."< br>
"Fuck...that makes so much sense!"
Zhang Hui looked at Ren Qiang with eyes full of admiration.
Zhang Hui has been with Ren Qiang for these years and feels that he has learned many of Ren Qiang's skills, but now it seems that he is still far behind.
Solving crimes requires more than just skills. In fact, solving crimes involves people’s hearts.
What the murderer was thinking, if the investigators can figure it out, then he will not be far away from being caught.
After all, isn’t the murderer just playing a hide-and-seek game with the police?
Hide the motive of murder, hide the body, hide the murder weapon, etc. The murderer has only one fundamental purpose, which is to hide himself.
If a murderer's thoughts and thoughts can be guessed by the police handling the case, then catching him is definitely not far away.
In the current investigation office, Liu Guodong and Lu Chuan did not go back. After Lu Chuan finished comparing Su Xiaogang's footprints with those at the crime scene, it was already very late.
Actually, when Ren Qiang and Zhang Hui brought Su Xiaogang back, Lu Chuan only took one look and knew that this man was not the murderer.
There's something wrong with his height.
Although Wu Xiaogang is strong and 1.81 meters tall, the difference between him and Lu Chuan's murderer is between 1.82 and 1.84 meters tall. The difference is very small, but in fact the gap is huge.
In the footprint identification analysis, it is very scientific to estimate the height of the footprint owner based on the length of the footprint and other data.
1.82 to 1.84 meters. In fact, the calculation result given by Lu Chuan was 1.83 meters.
A range is given up and down, and fault tolerance factors are already considered in it.
The height is definitely within this range. It cannot be shorter than 1.82 meters, nor taller than 1.84 meters, not even one centimeter.
Sure enough, in the final comparison, Su Xiaogang's footprints were completely different from those found at the scene.
In fact, the footprints left by different people, even if their feet are the same length, are different.
After all, there are many people wearing the same shoe size.
People from 1.7 meters tall to 1.75 meters tall can most likely wear 42 shoes. However, because everyone has different weights and different walking postures, everyone’s soles of feet have different focus points. There is a difference.
For example, some people experience greater stress on the outside of their feet, while some people experience greater stress on the inside of their feet.
Some people walk with their heels first, while others like to wade.
Su Xiaogang's footsteps put more force on the inner side of his foot, but the murderer's footprints put more force on the inner side.
Early the next morning.
Zhang Hui rushed to Haizhou University of Science and Technology.
In the experiment, Zhang Hui met Wang Qianqian.
"You are..."
"Hello, classmate Wang. My name is Zhang Hui. I am from the Haizhou City Criminal Investigation Detachment. I have some information that I need to verify with you."
Criminal Investigation Detachment?
Wang Qianqian was slightly startled. She did not expect that the police would come looking for her.
Other Wang Qianqian’s classmates also looked at Wang Qianqian doubtfully.
“I... seem to have committed no crime, right?”
"It's some other situation, can we talk about it?" Zhang Hui did not elaborate. He was a criminal police officer, not a policeman at the police station. Wang Qianqian's part-time job was not his business.
"Go over, go early and come back early."
Wang Qianqian's instructor nodded, and then he left the computer and stood up: "Follow me, there is an empty room next to you. Let’s talk in the classroom.”
In the classroom, Zhang Hui took out Zhang Xiaofeng’s photo without beating around the bush.
"Wang Qianqian, do you know this person?"
Taking the photo, Wang Qianqian's face turned pale.
After all, the two of them had an intimate encounter at the Nebula Hotel at noon the day before yesterday. How could they forget so quickly?
"I...you..."
Wang Qianqian never thought that the police would come after she only did it a few times.
"Wang Qianqian, don't be nervous. I am a criminal police officer. The matter between you and Zhang Xiaofeng is not within my jurisdiction. I want to ask you, do you know where he went after you and him...at noon the day before yesterday?"< br>
Wang Qianqian was greatly relieved when she heard that Zhang Hui was not here to arrest her.
This is a school. If I were arrested by the police for something like that, this graduate student... probably wouldn't be able to continue studying.
"I...I really have no choice. My boyfriend has graduated and has no job, so I..."
Wang Qianqian gave a very thorough explanation, starting with why she took this path. .
She did meet Su Xiaogang at the Pullman Fitness Club, but unlike other people, Wang Qianqian really went there to work out.
It was only later that I bought an iPhone for my boyfriend that I had the first time.
That time, she made ten thousand yuan.
Later, only her boyfriend was away, so she came out to pick up guests when she had time.
The minimum is 5,000 each time, and the most is 8,000 to 10,000.
"That man... was introduced to me by Su Xiaogang. It was the first time I met him."
"At noon that day when we...were in the middle of the day, someone sent him a WeChat call. It must be something important. "But I didn't hear what he said."
"How do you know it's important?"
"Well...because he was...but he...looked." When I got to the WeChat call, I stopped, then I answered the WeChat call first, and then came back..."
Zhang Hui nodded.
Wang Qianqian is very beautiful, and she really only works part-time. It must be important for the other party to stop her at the critical moment.
"Are there any other unusual findings?"
"Well... the other party should be a woman."
"Why, didn't you hear what he said? "
"I guess, because he was more... more excited when he came back, and after a while... he..."
"Besides, he also said something about Xiaohui."
Xiaohui?
“Is it a person’s name?”
“It should be, that’s what he called him last time.”
“When did he leave?”
The surveillance system at Nebula Hotel is ineffective, perhaps in order not to leave any clues. It has been broken for more than a month and has not been repaired.
The colleagues from the second team who went to investigate did not find the last video of Zhang Xiaofeng’s disappearance.
"It was around 1:30 at noon. I was afraid of being seen, so I asked him to leave first. I followed behind. I saw him going out and entering Wenhua Lane. I took a bus back to school from the square."
Cultural Alley?
Why did Zhang Xiaofeng go to Wenhua Lane?
