Things that solve crimes

Ant Diamond Center is actually a small city. 30% of the world's rough diamonds are shipped to this city every year, and valuable cut diamonds are also sold.

When Qin Henian and Cao Qiu arrived, the manager was already waiting for them.

Without further ado, the two asked the manager to take them directly to the vault.

The manager looked sad, "Our vault has external surveillance cameras, turntable locks, key locks, magnetic field sensors, and locked steel doors."

"There are also internal surveillance cameras, light sensors, heat sensors, and a keypad to disarm the sensors."

"But the nine security measures still failed to prevent the robbers."

At this point, the manager felt bitter in his heart. If the things couldn't be found, he would be the end of his job as a manager.

Entering the vault, the first thing you notice is the empty safe.

Seeing these safes, the manager's face became even more bitter, "Those stolen items were placed in these empty safes, 160 in total."

The two checked the safes again, but unfortunately found no clues.

Taking off his white gloves, Qin Henian asked thoughtfully, "Did you ask someone to design your vault?"

The manager puffed up his chest and said, "Of course, we asked Mr. Wang to design it. The vaults he designed have never been robbed."

Immediately, his waist suddenly bent down, oh, they were the only ones robbed.

After asking the manager for Mr. Wang's address, the two immediately went to Mr. Wang's home.

In the car, Cao Qiu asked, "Do you doubt the treasury designer?"

"It may not be him. The treasury information may have been leaked from him. Let's take a look first." Qin Henian said.

Mr. Wang's home is in the famous villa area of ​​Luyeshuiju, so the security is naturally strong, but once the police officer ID is taken out, nothing will happen.

The property management manager personally took the two people to Mr. Wang’s home.

Cao Qiu got straight to the point, "Did you design the vault at Ant Diamond Center?"

Mr. Wang nodded, "That's right."

"Then have you ever disclosed the information about Ant Diamond Center's vault to anyone? Even if it was unintentionally." Cao Qiu asked again.

Mr. Wang looked a little unhappy, "No, disclosing information is a taboo in our industry."

"Mr. Wang, do you still have the treasury design drawings?" Qin Henian asked.

"Still." Mr. Wang said.

Qin Henian asked again, "Can you let us take a look?"

"Wait a minute." Mr. Wang stood up and walked upstairs.

Ten minutes later, Mr. Wang hurried downstairs, looking panicked and saying, "The drawings are missing."

Their expressions changed drastically. They went upstairs and entered the bedroom. Mr. Wang pointed to the empty safe and said, "I put the drawings in the safe, but when I opened it just now, the drawings were gone."

The two of them suddenly thought that they had found the reason why the vault information was leaked. It turned out that the design drawings were stolen.

"Mr. Wang, how often do you check the safe?" Cao Qiu asked.

Wang Gongsheng replied, "I made this design a long time ago. I used to check it frequently. Now that I am older, I haven't looked at it for a long time."

As he said this, he had second thoughts. The police came to the door and the drawings disappeared. Could it be...

He quickly asked, "Something happened to the Ant Diamond Center vault?"

After pondering for a moment, Cao Qiu said, "The news this morning is that the treasury was robbed."

"Well" Mr. Wang clutched his chest and fell down directly. The property management manager next to him quickly held him up.
