"This is a schematic diagram of the crime scene of that year......" After Zhao Yu raised a question, Miao Ying called up the floor plan of the rural cooperative that year and introduced it in detail for everyone, "Look here, the internal structure of the cooperative is basically the same as that of the regular bank at that time. The outside is a waiting area for customers, and the inside is a counter area for employees.

"In order to prevent accidents, the entrances and exits to the bank counter area are double-layered, and if you open one of the doors, you will not be able to enter the counter.

When the police came to the scene to investigate, they found that Wang Xuejun, the director of the cooperative, had collapsed in the area between the two doors, both of which were open. Wang Xuejun was shot in the head and died on the spot, but after a forensic examination, it was found that there were residual traces of ether in his mouth and nose, and it was suspected that he had been in a coma before his death......"

"yes...... It's quite strange!" Ran Tao pondered, "Since Yang Zebiao's money has been received and Wang Xuejun is also unconscious, why do you want to shoot him?

"No hatred!" Miao Ying replied affirmatively, "Not only do the two have no hatred, but the relationship is not bad." Previously, Wang Xuejun also recommended Yang Zebiao to work in the municipal unit......"

"I understand what Team Leader Zhao meant!" Gao Facai nodded and said, "The same is true of Team Leader Wu Fangfang's murder, she has been suffocated and unconscious, but she was still brutally killed by the murderer, which is a bit illogical!"

"However, the same method ......," Wu Xiumin said, "but it shows that the two cases are significantly related! Since Yang Zebiao's DNA was found in Wu Fangfang's nails, Yang Zebiao must still be the biggest suspect!"

"Sister Wu, let's listen to the whole case!"

Zhao Yu nodded at Miao Ying, and Miao Ying continued to tell the floor plan: "According to other employees of the cooperative, because the cooperative is located in a village or town, their management system is not strict on weekdays. Basically, the employees on duty that day can open those two doors.

"The safe is kept by two separate people, one with the code and the other with the key. But it just so happened that Yang Zebiao was the one who knew the password, so as long as he stunned Wang Xuejun and got his key, he could open the safe!

"Okay...... Miao Ying pointed to the screen with her hand, "Next, let's restore the whole process according to the video recording before it was turned off."

"First of all, the cooperative, like the bank, does not keep any money in the store, and every day the escort delivers the money in the morning and all the money back to the vault in the evening.

According to the escort who was in charge of delivering the money that day, they delivered the 800,000 yuan in cash to the cooperative at 8:45 on the day of the crime. After it was delivered, it was signed by Wang Xuejun and Yang Zebiao together.

"Due to the distance between the town and the vault, the escort often delivers the money here as the last stop, so the money is delivered relatively late. At that time, it was almost time for the cooperative to open, and inside the door surveillance, it could be seen that there were already customers waiting outside the door. And those customers were the later victims!

From the surveillance camera, it can be clearly seen that after the cash was sent into the counter area, it was indeed put into the safe by Wang Xuejun and Yang Zebiao.

Then the two of them began to do their own work and get ready.

It can be seen in the camera that when Wang Xuejun went out to open the gate of the cooperative, Yang Zebiao suddenly came to the monitoring controller quickly, and after that, the camera was all black!

"The monitoring equipment had a backup power supply, but Yang Zebiao unplugged the backup power supply and all the connecting cables! The monitoring equipment in those days was not as developed as it is today, and it was all handled by the bank itself, and it could not be controlled remotely, and there was no alarm triggering device.

So no one knew at the time that Yang Zebiao had turned off the surveillance. No one knows what happened to the co-op after the surveillance was shut down.

"Later, when the police received the report and rushed to the scene, they only saw a tragic scene inside the cooperative, and five victims were shot to death! The 800,000 yuan in cash in the safe was missing!" Speaking of this, Miao Ying called up some scenes of the crime scene and said, "Except for Wang Xuejun, who died in the double-door mezzanine, the other four deceased all died outside the counter area.

Among them, Zhao Meng, a 38-year-old dairy farm owner, is the big customer who made an appointment with the cooperative to withdraw money;

Xie Mengqin, a 32-year-old female owner of a local private agricultural material company, and her daughter, who was not yet 6 years old, were at the time. Xie Mengqin went to handle a huge amount of transfer business that day, and she also made an appointment in advance!

In addition, there was a security guard named Wang Zhongcai, who died at the entrance of the cooperative. In fact, strictly speaking, there were no professional security guards in a cooperative of the size of Ziliu Town back then, and Wang Zhongcai, who was 54 years old at the time, was more like a cleaner, responsible for cleaning and cleaning on weekdays.

"Of the five victims, except for the girl who was shot in the chest, all the others were shot in the head and killed with one shot!

After Miao Ying finished speaking, the scene couldn't help but fall into silence. People are looking back at the case in their minds, and such a tragic case, in addition to being outrageous, obviously has too many doubts.

"The experts of the 03 special investigation team believe," Miao Ying said, "Yang Zebiao's social contacts are very simple, and the chance of getting a pistol is not very high." Moreover, judging from the traces of the victim being shot, the murderer has a certain amount of experience in shooting, but Yang Zebiao has never been a soldier and has never touched a pistol.

Therefore, experts unanimously determined that Yang Zebiao should still have accomplices!

"The reason why he wants to turn off the surveillance is that he doesn't want to expose his accomplices. And after he turned off the surveillance video, his accomplices entered the cooperative and committed this shocking crime with him! So the real murderer is not necessarily Yang Zebiao himself!

"Moreover, Yang Zebiao has not heard from him for so many years, and experts also suspect that after the incident, Yang Zebiao may have been killed!"

"But ......," Ran Tao shook his head and said, "Now it seems that Yang Zebiao is not only alive, but also able to come out and kill people!"

"I talked to Captain Jin about this case before...... Zhao Yu said slowly, "He thinks the most critical part of this case is the fifth question!"

"Why did the murderer kill people?" Zeng Ke had a better memory, and immediately retold the fifth suspicion.

"Just imagine," Zhao Yu said, "Yang Zebiao stunned the director at the counter, and then opened the safe and took out 800,000 cash. Whether there are accomplices or not, why kill people when the money is already in hand?

"If it's just for the money, you can take the money and run!

"If you're worried that those customers will call the police in advance and delay your escape, you can snatch their phones and tie them up, instead of killing people, it's that big, right?"

"Could it be ......," Wu Xiumin guessed, "that there is a problem with those victims? The main purpose of the murderer is not money, but to a certain victim?"

"The 03 special investigation team has investigated all the relationships of the victims, and although several suspects have been found, they have all been ruled out in the end!"

"That's it...... What happened to the accident!" Ran Tao guessed, "Those customers found out that Yang Zebiao had a problem and wanted to stop him, so Yang Zebiao had to kill everyone?"

"There was no trace of a fight at the scene!" Miao Ying said, "Judging from the scene of the deceased's death, the murderer killed very decisively, as if it had been premeditated!"

"Tut-tut......" Ran Tao shrugged his shoulders with a bitter face, and said helplessly, "This is interesting! I finally understand now why the Nonghe blood case can be included in the five major unsolved cases!"
