Things that solve crimes

Qin Henian took a breath and asked quickly, "Does the manager know that he talks in his sleep?"

The woman smiled bitterly and shook her head. She thought it was not a big deal, so she didn't tell her husband.

Now, she would regret it to death. If the things were not recovered, her husband would be dead.

……

After the manager's wife left, Qin Henian and Cao Qiu returned to the office.

Qin Henian poured two glasses of water, one for himself and one for Cao Qiu. "How did the information about the treasury password leak out? Now we have found it."

Cao Qiu took the water and frowned, "Do you think the manager was talking in his sleep?"

No, apart from my wife, who else knows about talking in sleep?

Qin Henian held the water glass with a relaxed expression, "We have investigated the manager and found that he is very alert and always maintains a certain level of vigilance when meeting strangers."

"There are only three kinds of people who can make him sleep peacefully: his wife, his lover and his friends."

"With the manager's vigilant temperament, he will never sleep peacefully in front of strangers."

"But if you are at a friend's house, or a friend with whom you have a good relationship, your vigilance will be reduced a lot."

"And it's normal to stay at a friend's house, isn't it? If you have the intention, it's easy to hear the manager talking in his sleep."

"The manager's wife can rule out suspicion for the time being. After all, it was she who told us the news."

"As for the lover, the manager has no lover, so he can directly eliminate this option."

"So the boss should be friends with the manager, especially with the manager's wife."

"Because the manager doesn't even know that he can talk in his sleep, but the boss knows." Cao Qiu interjected.

Qin Henian took a sip of water before continuing, "Yes, and the boss is not only the manager's friend, but also the manager's client."

"Both the Garden Bank and Ant Diamond Center have a lot of things in their vaults, and there are many types, such as U.S. dollars, diamonds, gold, gems..."

"However, the criminal gang only took three things, diamonds, gold and jewelry. Among the jewelry, they only took diamond rings."

"There are so many things, but only these three are taken. It shows that the boss has a purpose when taking things."

"And the three types of things are not placed in the same place in the vault. How does the boss know where they are placed?"

"Unless he enters the vault and knows exactly where the diamonds are and where the jewelry is."

"The only ones who can successfully enter the vault without making the manager suspicious are the customers."

"This boss is very patient." Cao Qiu hummed. After becoming the manager's client and doing more business, he will be able to become friends. This process takes a lot of time.

The two identified the target, and the police immediately investigated the manager's customer base one by one.

Soon, the police screened out 15 people who met the target, and conducted in-depth investigations on these 15 people.

A person slowly surfaced.

In the interrogation room, a middle-aged man sat on a chair with a calm expression.

As time passed by, the man's expression remained unchanged.

Cao Qiu looked at the calm man on the surveillance camera and frowned, "This interrogation is not easy to handle."

Ordinary prisoners will only become more and more panicked or irritable when left alone in the interrogation room. It will be much easier to do the interrogation at this time.

Being calm and unhurried like this is the hardest thing to do.

Qin Henian also stared at the surveillance, "Can the person who can plan the bank vault robbery be an ordinary person?"

"If you are not strong in all aspects, you would have been caught long ago."

Cao Qiu sighed and waved his hand, "Let's go to the interrogation."

There should be two police officers next to them, one fat and one thin.

Two interrogation detectives entered the interrogation room. After sitting down, the tall and thin detective asked, "Name, gender, occupation..."

The man smiled and said, "Colin, male, security alarm expert..."

"Do you know why I'm looking for you today?" The tall and thin detective's face suddenly turned serious.

Colin shook his head.

"Where were you on the night of July 7th?" the tall and thin detective asked sharply.

Colin's expression remained unchanged, "Sleep at home."

"Are you friends with the manager of Ant Diamond Center?" the tall detective asked again.

Colin replied, "The relationship is not bad, we have had a few meals."

"Not only that, you and the manager often go out to eat, and you even invited the manager's family to your home." The tall and thin detective stared at Colin, his suspicious eyes falling on him.

Colin shrugged nonchalantly, "This police officer, even if we have a good relationship, it's not illegal."

"Then did you know that the manager can talk in his sleep?" The tall and thin detective stared at Colin with burning eyes.

If Colin answers yes, it proves that he has the opportunity to know the treasury information, and the suspicion becomes stronger.

If Colin answered that he didn't know, that would be better. The police already knew from the manager's wife that the manager had complained to Colin about sleepwalking.

Colin's smile disappeared, the corners of his mouth straightened, and his expression became slightly gloomy, "I know."

"Did you hear the manager talk about the vault information of Ant Diamond Center when he was talking in his sleep?" The tall and lanky detective took a step closer.

Colin sneered, "I haven't heard of it, I don't know."
