Sun Wenxuan's case could be big or small.
After Han Bin understood the general situation, he handed him over to the Guang 'an Police Station, which was Han Weidong's territory. It was very convenient for Han Bin to interrogate him or understand the situation.
Sun Wenxuan was taken away by the police. Only Han Bin, Jiang Yang, and Bao Xing were left on the top floor. The surroundings immediately became quiet.
This kind of environment was also conducive to Han Bin's thinking.
The technical team had already been to the scene. Han Bin didn't expect to find new evidence at the scene. He just wanted to experience the environment of the crime scene firsthand.
Sometimes, he could also learn some information about the suspect through the environment of the crime.
The environment on the top floor was relatively closed. Usually, no one came up here. The suspect chose to commit the crime here, probably because he liked the hidden environment here.
If he wanted to go to the top floor, he had to take the elevator first, then he had to climb the stairs. It was more difficult to move the body, and it was easy to be discovered.
Therefore, Han Bin was more inclined to believe that the murderer killed the victim on the top floor.
It was still the same as before. People rarely came to places like the top floor.
Why was a young woman willing to come to the top floor? This was a little thought-provoking.
In Han Bin's opinion, there should be three possibilities.
The first possibility was that the victim was taken to the top floor by the suspect.
The second possibility was that the victim was tricked to the top floor by the suspect.
The third possibility was that the suspect came to the top of the building voluntarily.
From the current situation, the first two were more likely.
The most unfortunate thing was that the surveillance of the community was blocked. If the surveillance was still there, as long as they checked the surveillance, they could find clues of the suspect.
Also, why did the suspect choose to commit the crime here? Why did he throw the victim into the water tower? Was it accidental or intentional?
There were too few clues at the moment, and Han Bin couldn't make a judgment.
Han Bin walked carefully from the door of the top floor to the gate of the water tower. He basically knew the situation of the crime scene.
It was almost noon when Han Bin and the other two came down from the top floor.
Han Weidong treated them to a restaurant a little further away. After such a thing happened, no one wanted to eat nearby.
With his son's colleagues around, Han Weidong naturally wouldn't be stingy. He ordered a table full of dishes and warmly welcomed Jiang Yang and Bao Xing.
During the meal, Han Bin asked Cui Hao about the shoe store. The reason why he didn't ask Han Weidong was that Han Weidong didn't go out much. He stayed in the police station most of the time. He didn't know the situation on the street as well as Cui Hao.
After Han Bin said that, Cui Hao had a little impression of the shoe store. He knew the approximate location, but he couldn't remember it.
On the other hand, a police officer who often went out on patrol was more familiar with the situation on the street. According to him, the name of the shoe store should be Cool Trend Shoe Store.
When Han Bin asked him to lead the way, he readily agreed.
Well, he didn't have a choice.
After dinner, Han Bin said goodbye to his father and drove to Cool Trend Shoe Store.
The father and son saw each other every day and even had breakfast together in the morning. They didn't have much to talk about.
As for the work, Han Weidong was more experienced than him and had already prepared for it. There was no need for Han Bin to worry.
What Han Bin needed to do now was to solve the case as soon as possible and give an explanation to the people.
It was disgusting to sink corpses in the water tower. It was simply not done by humans. Zhou Jingjing didn't have an infectious disease. If there was an infectious disease, it would harm the people in a community.
Cool Trend Shoe Store was on Guang 'an Street, a few minutes' drive from where they ate.
The shop was not small. The black plaque was very different from the style of the surrounding shops. It looked a little abrupt and could be seen from a distance.
In order to avoid being too eye-catching, Han Bin asked the police officer to stay in the car.
Han Bin took Jiang Yang and Bao Xing into the store.
"Welcome!" On the right side of the store stood a waitress in her early twenties. She wore a black T-shirt with the word "Cool Trend" printed on it and tight jeans. She had a good figure.
"Hello, gentlemen. What kind of shoes do you want?"
"Let's see for ourselves."
After that, Han Bin and the other two began to search the store.
After a while, Bao Xing shouted, "Team … Brother Bin, come over here. I think this pair of shoes looks good."
Han Bin understood and walked over. It was a black sandal with three dog paw prints on the ground.
Han Bin picked up the shoe and examined it carefully. The outline, spacing, and size of the dog paw prints were almost the same as the ones at the construction site.
Han Bin waved his hand, "Beauty."
The saleswoman walked over, "Sir, do you want this shoe?"
"Is your boss here?"
"Ah?" The saleswoman was a little surprised.
"We are the police." Bao Xing showed his police badge, "Call your boss over. We have something to discuss with him."
"Okay." The saleswoman was a little surprised and nervous. She didn't dare to ask more and turned to leave.
After a while, a woman in her thirties came over. She had a rather voluptuous figure and walked towards Han Bin's direction, "Hello, what can I do for you?"
"You are the boss here?"
"Yes."
Bao Xing showed his police badge again, "We are the police, and we want to know something from you."
"What's the matter?"
"How many shoes do you have here with dog paw prints?"
The female boss frowned and thought for a moment, "Only two, one for men and one for women."
Han Bin said, "Show me the sales records of these two shoes."
"Officer, is there any problem with these two shoes?"
Han Bin didn't answer and continued, "Show me the surveillance footage."
The lady boss became more and more uncertain, "Officer, I'm willing to cooperate with you, but can you tell me what's the matter?"
"We are investigating a criminal case. We suspect that the person involved may have come to your store to buy shoes. Please cooperate, thank you."
"No problem, I'll go get the sales records and surveillance footage."
The lady boss walked towards the counter. Bao Xing followed and asked, "Lady boss, how long can you keep the surveillance footage here?"
"About two weeks."
Bao Xing spread his hands at Han Bin.
Han Bin said, "Let's get it out first."
The lady boss was also a quick-witted person. She quickly checked the purchase records of the shoes. There were more than a dozen pairs of these shoes sold, and on June 1, the same person bought two pairs, one for men and one for women. It should be the victim, Zhou Jingjing.
Han Bin now had two guesses. The first was that Zhou Jingjing gave the men's shoes to the murderer, and then the murderer wore the shoes to kill Lu Jingfang.
The other possibility was that Zhou Jingjing gave the shoes to Yan Heyu, but Yan Heyu was not the murderer.
After killing Zhou Jingjing, the murderer thought that her shoes could cover up his footprints, so he bought a pair of shoes of the same style. If that was the case, the suspect was likely to be on the list of subsequent buyers.
If the suspect bought the shoes later, there might still be surveillance footage left.
Of course, these were all Han Bin's guesses. The specific situation would only be clear after further investigation.
In order to better compare the shoe prints, Han Bin bought a pair of the same shoes with dog paw prints, ready to take it back for further research.
It was already past three in the afternoon when he returned to the Municipal Public Security Bureau.
As expected, Ma Jingbo was called to a meeting.
Although the leaders of the Municipal Public Security Bureau had not set the tone, they could not delay the investigation. Han Bin gave a simple assignment.
Bao Xing went to check Yan Heyu's information.
Jiang Yang went to the Technology Department to check Zhou Jingjing's phone number.
Han Bin made himself a cup of tea, found the dating show "Let's Generate Electricity Together" on the Internet, and looked at Zhou Jingjing's previous competition videos.
Zhou Jingjing was actually quite pretty. She had a slim figure, an oval face, small canine teeth, and a coquettish temperament. She was definitely a cute girl.
Zhou Jingjing was fashionable and beautiful. She had a good personality, at least on the show.
Zhou Jingjing went on a total of three episodes. The first episode happened to be the episode where Lu Jingfang was taken away. The man who took Lu Jingfang away was called Ren Baitao, the founder and CEO of a financial management company. Han Bin did not understand the specifics, but it sounded very cool.
Zhou Jingjing was taken away in the third episode. The man who took her away was Yan Heyu. Just like Zhou Jingjing's parents said, Yan Heyu was indeed sunny and handsome. As soon as he came on the show, he performed a street dance, which attracted the screams of many female guests and audience members. In short, he was a handsome guy.
Han Bin took a screenshot and sent it to Bao Xing.
After watching three episodes of Zhou Jingjing's videos, Han Bin watched Lu Jingfang's videos again. He had a better understanding of these two women.
After watching these videos, Han Bin felt that it was necessary to go to the TV station and give a statement to the relevant personnel. Maybe he could get some valuable clues.
"Creak …" The door opened, and Bao Xing walked in from outside. He walked to the air conditioner and said, "Leader, the police system could not find Yan Heyu's identity."
