Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 409 The first clue

"It's hard to understand this. 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 it will cost?"

“It’s not the fish that matters, it’s where the fish is.”

"Su Xiaogang sells good products in the fitness club. Although some of them are average-looking, the prices are still very high."

"Haven't you heard a saying, there are two things men love most."

"First, persuade prostitutes to be good."

When Zhang Hui heard this...it made sense: "Where's the second one?"

"Haha, drag your mother-in-law's daughter into the water."

"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 could figure it out, then he would not be far away from being caught.

After all, isn't the murderer just playing a hide-and-seek game with the police?

Hiding the motive of murder, hiding the body, hiding 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.

Liu Guodong and Lu Chuan did not go back to the current investigation office. After Lu Chuan finished comparing Su Xiaogang's footprints with those at the crime scene, it was already very late.

In fact, 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 physically strong and 1 meters tall, the difference between him and Lu Chuan's murderer is between 81 and 1 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.

1.8 meters two to 1.8 meters four. In fact, the calculation result given by Lu Chuan was 1.8 meters three.

A range is given up and down, and fault tolerance factors are already taken into consideration.

The height is definitely within this range. It cannot be shorter than 1 meters, nor taller than 82 meters, not even one centimeter.

Sure enough, during 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 between 1.7 meters and 1.7 meters in height can most likely wear 42 shoes. However, because everyone has different weights and different walking postures, the focus of each person's soles of the feet is different.

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 stunned. She did not expect that the police would come looking for her.

Other Wang Qianqian’s classmates also looked at Wang Qianqian doubtfully.

"I... don't seem to have committed a 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 there and come back early."

Wang Qianqian's instructor nodded, then left the computer and stood up: "Follow me, there is an empty classroom next to you, let's chat somewhere."

In the classroom, Zhang Hui directly took out Zhang Xiaofeng's photo without mincing words.

"Wang Qianqian, do you know this person?"

After 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 it 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, after you and him... at noon the day before yesterday, do you know where he went?"

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. I..."

Wang Qianqian gave a very thorough explanation, starting from 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 1 yuan.

Later, when only her boyfriend was away, she came out to pick up guests when she had time.

The minimum is [-] each time, and the most is [-] to [-].

"That man... was introduced to me by Su Xiaogang. It was the first time I met him."

"At noon that day, when we were...someone called him on WeChat. It must have been something important, but I didn't hear what he said."

"How do you know it's important?"

"Well... because he was doing that... but when he... saw the WeChat call, he stopped, then 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 person should be a woman."

"Why, didn't you hear what he said?"

"I guessed it, because he was even more...excited after he came back, and after a while...he..."

"Besides, he also talked about Xiaohui and so on."

Xiaohui?

"Is it a person's name?"

"It should be, this is what he called at the end."

"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.

Colleagues from the second team who went to investigate did not find the last video of Zhang Xiaofeng’s disappearance.

"About 01:30 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 Cultural Alley?
