There are two cameras in the supermarket at 8:30, one on the corner of the warehouse door inside and one on the left corner of the entrance.
The two cameras are at an angle, covering the entire scene in the supermarket.
The camera on the corner of the warehouse door faces the supermarket entrance and can see the situation outside the supermarket.
Three days ago at 6:18 pm, Zhou Yang and Zhou Yang’s father were monitored standing on the left side of the supermarket door.
Due to the angle, Zhou Yang was all in the camera, and Zhou Yang's father could only see half of his face.
According to the information provided by Zhou Yang's father, Zhou Yang's mother was also present when he sent money to Zhou Yang, but apparently because of the angle, Zhou Yang's mother did not appear in the camera.
This is a franchised supermarket. The equipment is customized according to unified standards, and the surveillance video is of high definition.
“This, right here, Zhou Yang’s father is giving money to Zhou Yang.”
Zhou Yang’s father can be clearly seen in the surveillance video, handing a dozen cash to Zhou Yang’s hand inside.
Before handing over the cash, Zhou Yang seemed to have a few words with his father, which lasted about five minutes.
During the conversation, the two people's gestures kept changing, and Zhou Yang's expression seemed to be more impatient.
"Haha, this Zhou Yang...his father said that the two had a quarrel at that time, and his father asked him to find a girlfriend, get married early, and go home to see her when he had nothing to do."
< br>Although you can’t hear what they said in the video, Zhang Hui focused on getting to know Zhou Yang’s father during this conversation.
“Zhou Yang didn’t listen and just asked his father for money. Look, he took the money and left immediately.”
In the video, Zhou Yang’s father handed the money to Zhou Yang , the other party didn’t say a word, turned around and left.
The video continued to play and the two continued to watch.
Zhou Yang's father seemed to be stunned for a few seconds before turning and leaving.
Bump.
But the moment he turned around and walked in the opposite direction, Zhou Yang's father bumped into a stranger walking towards him.
Zhou Yang's father quickly apologized. At this time, a middle-aged woman appeared on the other side of the screen, who was Zhou Yang's mother.
The man who was hit by Zhou Yang's father didn't say anything, waved his hand and left directly.
"Brother Hui, please play back this surveillance video."
Zhang Hui looked at Lu Chuan: "This person Zhou Yang's father had an impression. After apologizing, the other party didn't say anything and just left. ”
Lu Chuan nodded, he had just seen it in the video.
The other party just waved his hand and left quickly.
However, what Lu Chuan paid attention to was not what this person said.
Zhang Hui rewinds the video and Lu Chuan takes over: "Brother Hui, I'll do it."
Zhang Hui's mind suddenly moved: "Is there something wrong with this person?"
"Not sure yet... Let's take a look at this first..."
The video freezes at the moment when the two collide.
Lu Chuan used the screenshot tool that came with his computer to capture a frame of the video.
Then use the system’s built-in picture viewing software to zoom in on the man’s shoes in the picture.
Black leather shoes, a bit old, Lu Chuan focused on enlarging the edges of the shoes.
"Brother Hui, this man...the wear on the edges of his shoes is almost the same as the footprints found at the scene!"
"You mean...this man is the murderer?"< br>
"This is not certain. In the video, you can only roughly see the edges of the sides of this man's leather shoes. The degree of wear is similar to the wear and tear of the footprints I found at the scene."
"But the soles cannot be seen in the video. Pattern, not sure."
"But this person... Judging from the time interval in the video, he should have seen Zhou Yang's father giving Zhou Yang cash."
"If. The other party wants to make money, so it should be possible to follow him at this time?"
Zhang Hui is not sure about Lu Chuan's judgment, but there is no other clue now.
"Let's go, there are other surveillance cameras next to this supermarket. Let's go look for them."
"Okay." The two of them copied the relevant videos in the supermarket and told the clerk at the front desk some precautions before leaving.
“Don’t touch the computer monitoring the video recently.”
“Don’t worry, we will definitely not move, but isn’t the salary of being a police officer particularly high now?”
Zhang Hui frowned. When he visited, he rarely encountered people saying that police salaries were high: "Why do you say that?"
The clerk nuzzled at the Cayenne outside the supermarket: "They all drive this car to handle cases, and the salary Not high?"
Zhang Hui turned to look at Lu Chuan who started the car and sighed.
“Brother, can you afford this thing with your salary?”
He hasn’t eaten or drank for ten years, and he can’t afford such a car.
After getting in the car, Zhang Hui sighed involuntarily.
"What's up, Brother Hui, you should be happy to have a clue."
"Ah? Yes, yes, yes, I'm happy."
Lu Chuan was in high spirits. As detectives, of course there are many opportunities to appear on scene, but there are very few opportunities to handle cases.
Especially this time, although Zhang Hui led the team to come out with him, from reasoning to command, it can be said that Lu Chuan was in charge.
"Brother Hui, there is a hotel opposite. There should be a camera at the door. Come and have a look?"
"Okay, go and have a look."
The car started, turned a corner, and arrived at the supermarket. The hotel diagonally opposite.
The same process, after Zhang Hui showed his ID, the hotel staff was very cooperative.
The hotel front desk manager is very talkative.
"Two police comrades, our hotel has just been renovated not long ago, and the equipment is the best."
"The surveillance at our gate is a wide-angle camera, and it is high-definition. I will ask the security guard to cooperate with you."
"Okay, then I'll trouble you."
"No trouble, no trouble. It is the obligation of every citizen to cooperate with the work of the people's police."
Very Quickly, several people arrived at the monitoring room.
"Hello, Manager Sun!"
The security guard's training is relatively formal. When the leader comes in, he immediately stands at attention and salutes.
"Xiao Hu, these two are comrades from the Public Security Bureau. We need to check the surveillance video. Please cooperate."
"Yes!"
Zhang Hui directly asked for the operation The security personnel who monitored the video adjusted the video to 6:18 three days ago.
The other party is very skilled in operating the video, and as Manager Sun said, the hotel's hardware equipment is indeed not bad.
When the security guards search for surveillance, they are very fast.
Actually, few monitoring devices can do this.
Surveillance video, because of the large storage capacity, the computer processes it very slowly.
And in order to reduce costs, many monitoring equipment only install large hard disks, but the computer configuration is very low.
This leads to slow speed and frequent freezes when querying videos.
Two minutes later, security guard Xiao Hu stood up: "Manager Sun, it's done."
Zhang Hui and Lu Chuan came to the computer: "Here, you can see it!"
The upper left corner of the surveillance screen is facing the entrance of the eight-thirty supermarket.
In the screen, you can see Zhou Yang's father giving money to Zhou Yang.
"Look here, this side of the supermarket."
In the picture, Zhang Hui saw a woman standing on the right side of the supermarket at 8:30. Not far behind her, she bumped into Zhou Yang's father. man. (End of this chapter)
