The Yinglu City Investigation Team has been following up on this secret room murder case for nearly half a year.

Although the case was too strange and the evidence at the scene was not supported by Huihui and Tang Muqi's crime, the Yinglu City Detective Team spent a lot less energy on them in the later period.

However, this does not mean that the Yinglu City Detective Team has poor ability to investigate and collect evidence.

On the contrary, in this regard, it is relatively easy for each detective team to conduct in-depth investigations into some people's background within their jurisdiction.

The first thing to feedback the information was the investigation results about Yu Huihui.

"Team Leader Chen," the person in charge of this work is Ma Tao, deputy captain of the Yinglu City Detective Team.

"When we investigated the surveillance video of the hotel again, we found major clues."

Click.

Projection playback.

Haolai’s surveillance at the hotel was originally a cycle of one month, covering the monitoring.

But, coincidentally, at the end of July last year, they changed their computers.

The original hard drive just happened to be saved.

The video was July 19th.

"Duan Zhongxin went to Haozhang Hotel for dinner on July 19th."

"Because I drank some wine, I had teased Yu Huihui too much during the meal, and I almost started fighting at that time."

In the video, Duan Zhongxin said something when Yu Huihui came to serve the dishes.

Yu Huihui raised her hand and slapped him.

Immediately afterwards, Duan Zhongxin got up and was about to beat Yu Huihui, but was stopped by the waiter who rushed over.

Afterwards, the few people who had dinner with him also stepped forward and pulled away.

"Team leader Chen," Ma Tao pointed to the man who appeared in the video: "This man is Zhao Youqian, the owner of the hotel."

In the video, after Duan Zhongxin was seen sitting down cursingly, Zhao Youqian stepped forward and had a glass of wine with Duan Zhongxin and others.

Half an hour later, Duan Zhongxin and others left.

This situation was something that the Yinglu City Detective Team had not grasped before.

Yu Huihui actually had such a festival with Duan Zhongxin.

So, did Yu Huihui have a motive for committing the crime?

Chen Yan shook his head in his heart.

In the video, Yu Huihui looks more stingy.

Moreover, after the conflict with Duan Zhongxin, he didn't seem to care much.

I continued to drink with the guests at the door.

Such a woman would have the intention of killing people just because someone teased her for a few words?

What's more, Yu Huihui slapped Duan Zhongxin at that time.

"What's going on with this Zhao Youqian?"

After pausing the video, Chen Yan's eyes focused on Zhao Youqian who was drinking with Duan Zhongxin.

"This person is Yu Huihui's brother-in-law. Yu Huihui came to the park to work, just for her brother-in-law."

"And," Ma Tao pointed to Yu Huihui in the video: "We just discovered a situation when we were visiting and investigating."

"Oh? What's going on."

"The waiters and chefs in the hotel said that Yu Huihui and Zhao Youqian had a crush on each other."

Chen Yan was slightly surprised: "Don't you know Yu Huihui's sister?"

"Yu Huihui's sister is named Yu Rongrong. She takes care of her children in the city and doesn't usually go to hotels."

"So, I probably don't know."

"Check Zhao Youqian's information, especially with other women, whether it has an improper relationship."

Ma Tao nodded: "Yes."

Duan Zhongxin, one month before the incident, went to Haozailai Hotel.

Is this a coincidence?

Will Yu Huihui have the idea of ​​killing people because of this?

Decisive judgments are not yet possible.

However, at least we have discovered that we have not discovered before.

An hour later, the news in charge of the investigation of Tang Muqi also came back.

"Team leader Chen, Tang Muqi only came to the park to work as a security guard in January this year."

The person responsible for investigating Tang Muqi was Jiang Lin, the captain of the first team of the Yinglu City Detective Team.

"He is Zhang Baoshan's fellow townsman. At the beginning of the year, Zhang Baoshan introduced him to be a security guard."

"This person is usually honest and often works on night shifts."

"I have a good relationship with a lot of security guards."

"Don't smoke or drink, I usually stay in the dormitory after get off work."

"His wife cooks in the factory, which was also introduced by Zhang Baoshan."

"But," Jiang Lin paused: "The security guards we visited said that Tang Muqi and Zhang Baoshan's relationship was actually not good."

Um?

"They have a bad relationship?"

"Why?"

It shouldn't be.

Logically speaking, the work of Tang Muqi and his wife was introduced by Zhang Baoshan.

The couple should thank Zhang Baoshan.

How could the relationship between the two parties be bad?

"That's right," Jiang Lin handed a stack of materials to Chen Yan: "According to Tang Muqi's wife, they lent Zhang Baoshan 5,000 yuan in May this year."

"I originally agreed that Zhang Baoshan will return it to them in June."

"But, until now, I haven't given them the money."

"Also said that this is the agency fee for introducing the work to the couple."

"We have also contacted Zhang Baoshan to learn about this situation."

"It's true."

"And, Zhang Baoshan said that after the New Year, Tang Muqi and his wife insisted on asking him to find a job."

"He also gave a lot of things to find a good job."

"As a result, Tang Muqi and his wife did not mean at all, and Zhang Baoshan made such a move."

The information Jiang Lin brought back is very important.

Zhang Baoshang and Tang Muqi not only met each other, but also had some grudges.

This is also a situation that has not been discovered before.

Based on the current clues, survivor Yu Huihui is related to the victim Duan Zhongxin.

The reporter Zhang Baoshan and the survivor Tang Muqi are also related.

At present, although these relationships cannot have a direct relationship with the case.

However, if there is no direct relationship, it is the most relevant part.

Why are these four people?

Why not the other four people?

If there is a result, there must be a cause.

The murder in the secret room is the result, and everything now is the cause.

...

When Zhao Bing returned to the detective team, it was noon the next day.

Zhao Bing followed up on the investigation of Zhang Baoshan.

Conference room.

Zhao Bing began to report on the situation.
