Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

In the monitoring room, Wang Zhaokai asked the security guard to pull the surveillance to eight days ago, and Zhang Huan was soon discovered.

The choice of this time period is relatively easy. The forensic results show that Zhang Huan has been dead for 7 days. The police have spent more than a day on the investigation, which means that Zhang Huan should have died 8 days ago.

In addition, combined with some information provided by Zhang Miao, Zhang Huan stopped contacting his family from the evening 8 days ago.

Therefore, Wang Zhaokai focused his investigation on the relevant surveillance videos from 8 days ago.

Starting from the morning eight days ago until the evening, Wang Zhaokai arranged for people to gradually observe the video footage, and finally at 8:3 in the afternoon, they found Zhang Huan walking out of the community.

From the surveillance footage, we can see that Zhang Huan was dressed casually when he left the community, his hair was not tied up, and he was probably wearing pajamas. And within 30 minutes, he appeared in the surveillance camera of the community again. He was holding some vegetables and fruits in his hands.

"I have already conducted field visits and surveys on some owners and sales staff of vegetable and fruit shops at the entrance of the community."

Wang Zhaokai has learned that Zhang Huan left the community at 8:3 pm eight days ago to buy vegetables and fruits.

Although Zhang Huan is not tall, she is very beautiful and has a good temperament.

In addition, Zhang Huan rented a house in a small building in this community, and there were only a few residents.

Therefore, the vegetable and fruit stores at the surrounding entrances are relatively familiar to the residents of the community.

"Zhang Huan has lived in this community for about three years, so people in the vegetable and fruit shops know her."

"But according to the results of the current investigation, Zhang Huan last appeared in the community's surveillance camera eight days ago in the afternoon. No one at the vegetable store or the fruit store has seen Zhang Huan come out since then."

The community’s surveillance also shows that Zhang Huan has not appeared in the community’s surveillance from 8 days ago until now.

"There are two cross-linked surveillance cameras at the entrance of the community, so all people entering and leaving the community are covered by the surveillance cameras. In addition, although this community is not large, it is a closed community with only one entrance and exit, so the time when Zhang Huan was killed can be basically confirmed to be after 8:3 pm eight days ago."

"There are two things that can be confirmed. Zhang Huan's rental house should be where the first crime occurred. The surveillance camera at the door has no blind spots and can capture all the people entering and leaving the community..."

Lu Chuan began to analyze: "That means the murderer must have entered the community through the main gate. So we need to check all the strangers who entered the community that day, and all the people who left with backpacks, woven bags, suitcases, etc. that might be used to hold the body, and conduct a comprehensive investigation."

Of course, Wang Zhaokai had the same idea as Lu Chuan.

"I have arranged for someone to investigate in the monitoring room, but it may take some time."

In fact, this investigation is relatively easy to judge, because Zhang Huan last appeared in the surveillance video at 8:3 pm 18 days ago, and his body later appeared in the Liaohe River in Haizhou City.

The body should have been in the Liao River for about 7 days. In this case, the time from when Zhang Huan was killed to when he appeared in the Liao River should have spanned about one day.

No one rested the whole night. Everyone was reviewing the surveillance video frame by frame, marking out all the suspects.

In addition, the background investigation on Zhang Huan has basically been completed.

According to the information provided by Zhang Miao, plus some information provided by the company where Zhang Huan used to work, it shows that Zhang Huan himself does not have a partner.

However, Zhang Huan usually has a lot of expenses. Judging from his bank statements, his monthly expenses are approximately between 1 and 2 yuan.

"But Zhang Huan's salary is only over 5000 yuan per month."

In the conference room, everyone began to discuss Zhang Huan's situation.

"Did you notice that Zhang Huan would sometimes withdraw some money from his WeChat account to his salary card?"

Lu Chuan said.

Although Zhang Huan's cell phone could not be found, some clues could still be found in the bank statements. Zhang Huan only had one bank card, which was a salary card issued by the company. On the 12th of each month, the company paid him a salary of about 5000 to 6000 yuan per month.

In addition, the income of this bank card was withdrawn from Zhang Huan’s WeChat.

"I think Zhang Huan must have withdrawn some other income into the change."

Wang Zhaokai said.

"However, the exact amount of this income is still uncertain because Zhang Huan's phone is missing and the investigation on WeChat is difficult. We will definitely not be able to obtain any valuable clues or information in a short period of time."

"How's the investigation going on with the neighbors?"

Lu Chuan asked.

"There aren't many clues. According to Zhang Huan's neighbors, Zhang Huan has lived here quietly in the past few years, and generally no outsiders have come to visit her."

The survey results in the community did not provide any valuable information.

Although Zhang Huan was beautiful and everyone paid more attention to her, no one noticed any strange men coming to Zhang Huan's home.

"I have a clue."

The criminal police who was responsible for investigating clues in Zhang Huan’s company spoke.

"Oh? Tell me!"

This criminal policeman was a key member of the first squadron that Wang Zhaokai used to be in charge of, named Wang Qiang.

Wang Qiang stood up and walked to the whiteboard.

"When I was investigating Zhang Huan's work, I found that Zhang Huan had been working in this company since he came to Tianzhou City from his hometown three years ago."

"And I found something interesting. Zhang Huan has resigned from this company twice, and this is the third time."

When Wang Qiang said this, everyone straightened their backs. This information was interesting.

Since Zhang Huan resigned twice and was able to resign again, the third time means that he returned to work in this company after resigning.

What do you mean?
"This company is a clothing company. Zhang Huan works as an office clerk. His role is similar to that of a secretary, but he is not a real secretary."

"When doing a background check, from the information provided by her colleagues, it turned out that she might have some relationship with the boss of this company."

boss?

"Little San?"

This would explain a lot of problems. If Zhang Huan was a mistress, then his abnormal consumption behavior could be explained.

"Tell me more about the situation. Next, we will conduct relevant investigations around this clue."

Lu Chuan said.

It was already past six in the morning and the sky was already bright.

Early in the morning, Haizhou City called and compared the DNA information. The DNA information of the corpse was related to Zhang Miao, proving that the deceased was Zhang Huan! (End of this chapter)
