Ren Hongfeng's major discovery was a video recording.

There is a family on the first floor opposite the building where Gao Meimei lives, and a surveillance camera is installed in the living room.

It was originally used by parents to supervise and check the homework of children at home.

As a result, the camera was facing out the window that night.

Recorded what happened that night.

Chen Yan, Liang Gang, Ren Hongfeng and others watched the projection nervously.

The light is dim at night. Although the camera is high-definition, it can only see the silhouette of the person, and it cannot recognize the face.

April 20 at 23:08.

In the video, a woman and a man walk into the unit rented by Gao Meimei.

Then, the lights in the house where Gao Meimei was renting came on, and there were faint shadows flickering.

23:36.

The male figure left, five minutes later.

That is, at 23:41, another figure walked into the unit building.

I can't see my face, but I can tell it's long hair and a hat.

Because it was already late at night, no one came in or out of the unit building for a period of time after that.

21st at 0:32.

The lights in Gao Meimei's room went out, and the long-haired figure wearing a hat appeared in the monitor again.

Different from when he just came, the figure at this moment seems to be carrying a bag...

And Gao Meimei's figure never appeared again.

Ren Hongfeng paused the video playback, and his tone was a little excited: "And then, no one walked out of the unit until 6:30 in the morning when the sky was bright."

"So, this figure with long hair and a hat is very likely to be the murderer!"

The crowd is excited.

Long-haired figure in a hat...

Is the murderer a woman?

Although they couldn't see the appearance of the other party, everyone felt that they were one step closer to the murderer.

Chen Yan is also a little excited, this is a major clue: "Ren team, you arrange for someone to continue to investigate the residents in the Gaomeimei community to see if there is any video recording."

"In addition, according to the physical features in the existing video, track the suspect in the Sky Eye system!"

Why are you all excited?

It is because of the sky eye system.

Wearing a hat, long hair, and finding a woman with such characteristics in the middle of the night is difficult, but there is still hope.

Ren Hongfeng responded and immediately arranged for members of the task force to implement it.

Chen Yan looked at the video again: "This person is only a suspect at present, but the man who went back out of the house with Gao Meimei can't get rid of the suspicion either."

"Did DNA be extracted from the hair and dander collected from Gaomei's bed?"

Ren Hongfeng shook his head: "The technicians are still working..."

"Team Leader Chen, Gao Meimei's autopsy results are out!"

While Ren Hongfeng was speaking, the detective in charge of tracking the autopsy and testing brought back the news.

"As well as some hair and dander extracted from Gaomei Mei's home, we have completed DNA extraction and identity confirmation!"

Chen Yan received a dozen reports, somewhat surprised.

Although the house rented by Gao Meimei is cleaned regularly, it is impossible for the housekeeping staff to clean it very carefully.

Therefore, the man Gao Meimei once dated left a lot of traces.

There are 12 reports in Chen Yan's hands.

This shows that the colleagues of the detective team have extracted at least twelve body tissue samples from Gao Meimei's home.

After a glance, Chen Yan was a little surprised.

These 12 people... are really beyond Chen Yan's expectations.

Doctors, teachers, private business owners...

There are people in any industry, and they all have decent jobs.

This is also the reason why the colleagues of the detective team can be identified in a short period of time.

Even, there are staff here... and corpse plastic surgeons?

Hehe, it's a lot of variety.

"Subpoena all these twelve people to the case and ask them one by one."

As for Gao Meimei's autopsy results, it is not much different from Tan Xiaowen's.

Except Gao Meimei had intimate behavior before her death.

Of course, judging from the video, this intimate act was voluntary by Gao Meimei, and there is no possibility of violation.

"Team Leader Chen, the social software of the two deceased has been checked!"

Oh?

"what's the result?"

The detective in charge of checking the two's social software handed Chen Yan a stack of papers: "First of all, it's Tan Xiaowen. Judging from her social software, the people she contacted a year ago were Wechat businessmen."

"Later, most of the people who interacted after the live broadcast were fans in the live broadcast room. In the past six months, the one who had a relationship with Tan Xiaowen was the first and second list fans in her live broadcast room."

"Gao Meimei's social relationship...it's a little more complicated."

"She has a lot of groups, it's the kind of part-time job, and there are more people who have relationships..."

"More?" Ren Hongfeng on the side frowned, he had already found twelve, where else could he go: "How many people?"

The detective who reported it had a strange expression: "From the transfer records... a total of 97 in the past six months!"

97?

half a year!

It's almost a hundred people killed.

And, half a year and six months, that's equivalent to 16 people a month...

An average of 2 days a person!

Chen Yan was also a little surprised. This frequency was faster than his 100 blind date.

"Can you confirm the information of these 97 individuals?"

The detective frowned: "It is unlikely that all confirmations..."

"We have already checked, and there is another person who introduces customers to Gao Meimei. After every time, they transfer money to Gao Meimei there."

"However, the money that the wanderer pays over there is not necessarily a transfer, but also cash."

"As a result, it is difficult to query specific personnel information."

Ren Hongfeng understood what was going on as soon as he heard it.

There is a record of the transfer, which can be found at a glance.

But pay cash directly...

Chen Yan also scratched his head.

On the 100th blind date, he arrested a blind date and participated in some follow-up investigations at that time.

I know a little bit about the tricks inside, and I know that the detective is right However," Chen Yan flipped through the report in his hand: "It is still necessary to confirm as much information as possible on these people. "

Especially those who use cash for transactions.

Chen Yan actually had a hunch that the other party would definitely have had contact with Gao Meimei.

However, Chen Yan did not say anything.

After all, the images in the surveillance video showed that the other party had long hair.

There is a high possibility that the murderer was a woman.

"By the way, has the relationship between the two deceased been found out? Do they recognize each other?"

This is the focus of Chen Yan's attention.

If the relationship between the two can be found out, it may be possible to infer the motive of the murderer.

However, the detective in charge of this aspect shook his head: "There is no connection between the two from the mobile phone records of the two."

"We even checked the live broadcast rooms that Gao Meimei usually browses, and we didn't find that she was following Tan Xiaowen."

Chen Yan frowned: "That is to say, the two don't know each other and have no intersection?"

The detective shook his head.

This is very troublesome.

The two did not meet, and were killed by the murderer using the same method.

Why?

Did the murderer choose someone at random to start the attack!

impossible!

Absolutely impossible.

Whether Tan Xiaowen was killed or Gao Meimei was killed.

The murderer did not leave any valuable clues, and his actions were very meticulous.

It can't be a casual murder.

For example, the surveillance video at the door of Tan Xiaowen's house.

For example, if you commit crimes in a rental house where Gao Meimei provides services, if you don't follow Gao Meimei, how can you know where she provides that kind of service?

...

In the next few days, the task force spent intense and busy investigations.

However, just when everyone was still confused and there was no obvious progress in various clues.

Bad news!
