In the monitoring room, Wang Zhaokai asked the security guard to move the monitoring to eight days ago, and Zhang Huan was soon discovered.
The choice of this time period is relatively easy to handle. The results of the forensic examination showed that Zhang Huan had been dead for 7 days. Now the police took more than a day to handle the case, which means that Zhang Huan died. The time should be 8 days ago.
In addition, combined with some information provided by Zhang Miao, Zhang Huan did not contact his family since the night 8 days ago.
So what Wang Zhaokai focused on investigating was the relevant surveillance video from 8 days ago.
Starting from the morning eight days ago until the evening, Wang Zhaokai arranged for people to gradually observe the video, and finally discovered Zhang Huan walking out of the community at 3:18 in the afternoon.
, from the surveillance screen, it can be seen that Zhang Huan was dressed casually when he left the community, his hair was not tied up, and he was probably wearing pajamas. In less than 30 minutes, the other party appeared in the surveillance camera of the community again. The other party was carrying some vegetables and fruits in his hand.
“I have conducted interviews and surveys with some owners and sales staff of vegetable shops and fruit shops at the entrance of the community.”
Wang Zhaokai has learned that Zhang Huan 8 days ago After leaving the community at 3:18 pm, I went out to buy vegetables and fruits.
Although Zhang Huan is not tall, he looks very beautiful and has a good temperament.
In addition, there are not many buildings in the community where Zhang Huan rents, and there are only so many residents.
Therefore, the vegetable shops or fruit shops 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 everyone in the vegetable shop and fruit shop knows her."
"But according to the current investigation results, Look, the afternoon eight days ago was the last time Zhang Huan appeared in the surveillance of the community. No one in the vegetable shop or the fruit shop saw Zhang Huan come out again. "
The surveillance of the community. It also shows that from 8 days ago until now, Zhang Huan has never appeared in the community surveillance.
“There are two surveillance cameras at the entrance of the community that are intersecting, so all people entering and exiting the community have no blind spots and can be covered by the surveillance. In addition, although this community is not big, it is a closed community. There is only one exit, so the time when Zhang Huan was killed can basically be determined to be after 3:18 pm eight days ago.”
"If you say this, there should be two things that can be confirmed. Zhang Huan's rental house should be where the first crime occurred. Since the other door surveillance at the scene has no blind spots, it can capture all the people entering and leaving the community..."
Lu Chuan began to analyze: "That means the murderer probably came in from the main entrance of the community. This way, we checked all the strangers who entered the community that day, and all the people who left were carrying backpacks, woven bags, suitcases, etc. Conduct a comprehensive investigation on these things that are suspected to be able to contain corpses."
Of course Wang Zhaokai had the same idea on Lu Chuan's part.
"I have arranged for people to investigate in the control room, but it may take some time."
In fact, this investigation is relatively easy to judge, because Zhang Huan showed up last The time in the surveillance was 3:18 pm eight days ago, and his body later appeared in the Liaohe River in Haizhou City.
The body should have been in the Liaohe River for about 7 days. In this case, the time span from Zhang Huan's murder to the time it appeared in the Liaohe River should be about one day.
No one had any rest for the whole night. Everyone was watching the surveillance video frame by frame, marking all the suspects.
In addition, the background investigation on Zhang Huan is basically completed.
According to the information provided by Zhang Miao, plus some information provided by the company where Zhang Huan originally worked, it was shown that Zhang Huan himself did not have a partner.
However, Zhang Huan usually has a lot of expenses. Judging from his bank statements, Zhang Huan's monthly expenses are probably between 10,000 and 20,000.
"But Zhang Huan's salary is only more than 5,000 yuan per month."
In the conference room, everyone began to discuss Zhang Huan's situation.
"Have you noticed? Zhang Huan sometimes withdraws some money from WeChat change and puts it into his salary card."
Lu Chuan said.
Although Zhang Huan's mobile phone cannot be found, some clues can still be found from some information in the bank statements. Zhang Huan only has one bank card, which is a salary card issued by the company. The company pays wages on the 12th of every month, ranging from 5,000 to 6,000 yuan per month.
In addition, the income of this bank card was withdrawn from Zhang Huan’s WeChat account.
"I think Zhang Huan should have withdrawn some other income into the change."
Wang Zhaokai said.
“But the specific amount of these incomes is still uncertain, because Zhang Huan’s mobile phone cannot be found, and the related investigation on WeChat is more difficult. We will definitely not be able to get valuable clues and information in a short time. Information.”
"How about the neighbor's investigation?"
Lu Chuan asked.
"There aren't many clues. According to Zhang Huan's neighbors, Zhang Huan has been relatively quiet here in the past few years, and generally no outsiders come to see her."
Community The findings inside provide little valuable information.
Although Zhang Huan is beautiful and everyone pays more attention to her, no strange man came to Zhang Huan's home.
"I have a clue here."
The criminal policeman responsible for investigating clues in Zhang Huan's company said.
"Oh? Tell me!"
This criminal policeman is Wang Qiang, the backbone of the first squadron that Wang Zhaokai used to manage.
Wang Qiang stood up and walked to the whiteboard.
"When I was investigating Zhang Huan's related work, I found that Zhang Huan has been working in this company since he came to Tianzhou City from his hometown three years ago."
"And I discovered an interesting thing. 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 is interesting.
Since Zhang Huan was able to resign after resigning twice, the third time means that the other party returned to work in this company after resigning.
What does it mean?
"This company is a clothing company. Zhang Huan works as an in-house clerk. Her status is similar to that of a secretary, but she is not a real secretary."
"When doing background checks, from the information provided by her colleagues Look, the other party may have some relationship with the boss of this company.”
Boss?
"Mistress?"
This can explain a lot of problems. If Zhang Huan is the mistress, then his abnormal consumption situation will be explained.
"Let's talk about the situation specifically. Next, we will mainly carry out relevant investigations around this clue."
Lu Chuan said.
It was already past six o'clock in the morning, and it was already dawn.
In the early morning, there was a call from Haizhou City. According to the DNA information comparison, the DNA information of the corpse was related to Zhang Miao, proving that the deceased was Zhang Huan! (End of this chapter)
