After looking around, Liang Gang's expression was serious.

"Comrades," Liang Gang looked around: "The murder case of 415 live broadcast is surprisingly similar to the murder case of a rental house last night.

"After asking the superiors, the two cases are now officially handled together."

"Now each group is reporting on the situation."

Wang Jian glanced at Ren Hongfeng and leaned forward: "My group is responsible for the visit and investigation of Tan Xiaowen's residence. Let's talk about the situation here first."

"The deceased Tan Xiaowen has a simple and clear family background. Her parents are farming in the townships of the city, are honest and have no grudges with the villagers."

"So, the possibility of vendetta caused by parents is basically ruled out."

"Tan Xiaowen used to be a micro-business, selling some cosmetics, or cosmetic injections similar to hyaluronic acid. She started working as an anchor a year ago."

Chen Yan already knew the information about this, but he had a doubt: "I have watched the live video record of Tan Xiaowen when she was killed."

"At that time, she had called help, and her neighbors should be able to hear it, why didn't they respond?"

"That's right," Wang Jian looked at Chen Yan: "We have visited Tan Xiaowen's neighbors. According to them, this kind of life-saving sound has also appeared in the Tan Xiaowen family before."

"At that time, they called the police, and we also checked the police records. As a result, Tan Xiaowen was performing with the first brother on the list and was fined 2,000..."

Chen Yan nodded helplessly.

The next story is naturally the story of the wolf coming.

When I really called for help, no one came to save me.

As for why the deceased did not make any sound when cutting off facial tissue, Chen Yan knew.

The murderer seems to be familiar with the structure of the human body.

Tan Xiaowen's body and Gao Meimei's body were wounded in the vocal cords of the neck.

When the murderer committed the crime, he cut off the victim's vocal cords, which made them unable to speak and could only endure the pain.

The first neck is the cause of death because the deceased has too much blood.

Ren Hongfeng next reported: "The second deceased is Gao Meimei, and his profession is the reception desk of the beauty salon."

"We have already contacted her roommate. She is on a business trip and will return to Panshi tomorrow..."

Each group has successively completed reports on the case progress.

"Next, please ask Deputy Team Leader Chen Yan to deploy the next step of case handling."

Chen Yan stood up and walked to the case analysis board: "First, based on the murderer's methods of committing the crime, combined with the fact that no property was lost at the two murder scenes, and preliminary investigation, it can be preliminarily concluded that this is a retaliatory murder case."

Liang Gang and others couldn't help but nod.

This is basically confirmed.

The property of the two deceased people at the scene was not lost. The murderer was cruel in the crime and was obviously retaliatory murder.

When the deceased is awake, use a scalpel to remove the skin on the lower part of the body.

During the process, alcohol is even used to stimulate the victim to prevent him from falling into a coma.

In addition, the deceased was finally damaged by concentrated sulfuric acid. The severe pain actually caused the deceased to scratch the floor tiles and expose the finger bones.

It can be seen that he is extremely revengeful.

"First, do the trace identification of the murder weapon as quickly as possible."

Ren Hongfeng nodded. If the murderer leaves traces on the weapon, the speed of handling the case will be greatly accelerated.

"Second, check all surveillance records at Tan Xiaowen's doorstep, especially couriers and delivery guys, and try to find someone who tampers with the video."

If this person can be found, it is very likely that the other party is the murderer.

Even if you are not the murderer, you can follow the clues and find some clues.

"Third, immediately investigate the mobile phones of Tan Xiaowen's case, and also need to check Gao Meimei's mobile phone WeChat records, and check all the people who had sex with Tan Xiaowen and Gao Meimei within half a year."

Chen Yan paused and looked at the case analysis panel: "The murderer was extremely cautious in committing the crime."

"This person knows Tan Xiaowen and Gao Meimei's daily routines well. If you want to do this, just by observing and following it may not be possible."

Gu Zi

"So, it is very likely that the murderer had contacted the two victims directly."

"Finally, thoroughly investigate whether the two deceased had any intersections of life or work..."

Serial murder cases, hidden under the surface, must be some kind of internal connection.

This connection is very likely to discover the murderer's motive, and even predict the murderer's next move.

Because Chen Yan had a premonition that the other party was likely to commit the crime again!

...

The second serial case just happened. Although it was already eight o'clock in the evening, it was the best time to advance the case.

The task force is like a machine that is fully powered, starting all work according to Chen Yan's deployment.

The first feedback was the results of the trace identification on the weapon.

It's a pity.

Both weapons are ordinary scalpels, without any special features, and no fingerprints or other traces are left on them.

Only a small amount of blood that belongs to the victim was left behind, proving that the murderer used these two scalpels to cut off the victim's facial skin.

The clues of the murder weapon were broken.

However, Chen Yan didn't care too much, and it was expected that he would not find clues.

At nine o'clock, Wang Xuan came back to report: "Team leader Chen, the video at Tan Xiaowen's doorstep has been checked."

Chen Yan looked at Wang Xuan with a slightly disappointed look: "Didn't you notice?"

Wang Xuan shook his head: "The surveillance video in the community can only be retained for three days, and the surveillance video is covered by loops."

"Although we copied the video record at that time, we found no useful clues."

Chen Yan frowned slightly.

Chen Yan, who has received the system reward computer program specialization skills, knows that overwriting videos is not simply deleted, but difficult to recover.

Especially after so many days, I want to recover...

Disaster!

However, from this point of view, the murderer should be very familiar with the video surveillance situation in this community.

Only then did he dare to paste photos on the video surveillance camera so boldly.

etc!

Since the other party is so familiar with the surveillance here, is it possible that he has worked as a security guard here?

Chen Yan's pupils shrank slightly and he suddenly looked at Wang Xuan: "Have the surveillance camera in Tan Xiaowen rented a community recently been repaired, or have the personnel resigned?"

It is not impossible for the murderer to apply for a security guard in order to check in the case before the incident.

However, after hearing this, Wang Xuan shook his head: "I have seen the security guard in the community monitoring room. There are three people taking shifts, all of whom have worked for more than three years."

"Video maintenance is once a year, and this year's maintenance has not started yet..."

Chen Yan's eyes were condensed.

The clues to the video were basically cut off again.

As for Gao Meimei rented a house in Jiaheyuan Community on Haifeng Road, there was no surveillance in the community at all.

However, Chen Yan has asked someone to visit and investigate. Some residents have installed surveillance at their own homes, and perhaps it may not be possible to find any.

Other work is being carried out one after another, and the night is quietly passing by.

Chen Yan stayed up all night.

Standing in front of the case analysis board, flirting and thinking.

The clues of the murder weapon have now been cut off, and the videos at Tan Xiaowen’s doorstep provide no valuable clues.
Chapter completed!
