Chapter 359 DNA Information Confirms Identity (Normal Update and 1500 Months
Chapter 359 DNA information confirms identity (normal update and 1500 monthly votes plus update together!)
Inserting steel nails from Baihui acupoint?
Chen Yan had only seen this method of killing in novels before, and this was the first time he encountered it in real life.
This case...
It's a bit strange.
Why did the murderer use this method to kill people?
Although the cause of death of the victim has been found, it does not help the investigation of the case very much at present.
The steel nails found in the body of the deceased are about 5 cm long and rusted. They can be bought in any hardware store.
It is very difficult to determine the identity of the murderer by tracing the source of the steel nails.
Because the cause of death of the deceased is rather strange, Chen Yan followed Wang Meng to the autopsy room.
The steel nails have been taken out of the skull of the deceased and placed in a tray.
Chen Yan picked up the steel nails with tweezers and opened the visual gene lock to observe carefully.
The steel nails were covered with rust, and there were marks of knocking on the nail caps.
"Did you collect fingerprint information on the nails?"
Wang Meng shook his head: "We carefully checked the steel nails and found no useful information."
Chen Yan nodded, which was also within his expectations.
The crime scene was not the first scene where the deceased was killed.
During the process of dumping the body, the murderer did not leave any traces.
And from the current point of view, the murderer chose to dump the body in the Taipingfang self-built housing area, and the fundamental purpose was to use the demolition construction to destroy the body.
It was only because the homeless man Wu Guizhong accidentally discovered that the existence of the body was exposed.
Now we can only wait.
Wait for the identity information of the deceased to be determined, and the results of the visit to the residents around the self-built housing area.
Putting down the steel nails, Chen Yan walked to the dissection table: "Did the deceased have any signs of sexual assault before his death?"
Wang Meng nodded affirmatively: "We have collected residual menstrual fluid in the body of the deceased."
"At the same time, residual materials were also collected from the deceased's mouth and chest."
"DNA information analysis is being done now."
Wang Meng looked at the time on his watch: "In about two hours, the DNA information analysis will be completed."
"Okay, notify me as soon as you have news."
"Yes, Captain."
...
4 pm.
Regarding the identification of the deceased, Zhang Chaoyang has not sent back any news.
Zhao Bing is responsible for visiting and investigating the residents around the self-built housing area, and no valuable information has been sent back.
However, the DNA information collected from the deceased has been tested.
Wang Meng turned on the projector and began to report.
"Captain, we collected residual material samples from the deceased and analyzed a total of 4 types of DNA information."
Four types?
Chen Yan's expression was slightly startled. How could there be so many DNA information?
Could the deceased have been insulted in turn before his death?
Considering the appearance of the deceased, this possibility exists.
However, the clothes on the deceased were not messy, nor were there any special wrinkles.
If it was a series of insults...
Did the murderer re-dress the deceased?
"Please report in detail."
Wang Meng nodded and began to report: "We analyzed the residual material collected from the deceased's lower body and found three types of DNA information."
"The material collected from the chest analyzed two types of DNA information."
"The material collected from the mouth found one type of DNA information."
The projector listed the descriptions of all DNA information separately.
"The three types of DNA information found in the lower body overlap with the two types of DNA information on the chest."
"But the DNA information in the mouth does not overlap with all other DNA information."
"That is to say, the deceased had close contact with four men in a short period of time."
Having close contact with so many men in such a short period of time...
Could it be that the identity information of the deceased is a young lady who does not return home at night?
However, it is not likely.
The deceased has a good appearance, fair skin, and a good figure.
In particular, Chen Yan noticed the perfume used by the deceased at the scene.
Chen Yan had smelled the smell of this perfume on Shen Yunshu before.
Although Chen Yan didn't know the specific brand of this perfume, the perfume used by Shen Yunshu must be expensive.
How could a young lady who worked as a prostitute use such an expensive perfume?
And the clothes worn by the deceased.
Although Chen Yan didn't know the specific brand of the clothes, the material of the clothes was very good.
It was not cheap at first glance.
In addition, the deceased had worn a ring on the ring finger of her right hand, a bracelet on her left hand, and a necklace around her neck.
Analyzing from these details...
The economic conditions of the deceased should be very good.
It seems that she should not be a prostitute.
Chen Yan shook his head.
There is too little information at present to determine the identity of the deceased.
"Wang Meng, give the DNA information to Wang 5gang."
"Let him compare it in the DNA information database to see if he can find anything."
"Yes!"
In the office, Chen Yan paced back and forth.
A young woman had close contact with 4 people in a short period of time.
After being killed, her body was thrown into the self-built housing area late at night.
The rings, necklaces, and bracelets on her body all disappeared.
On the surface, it seems very likely to be a case of robbery and murder.
But generally speaking, most robbery and murder are crimes of passion.
Either it is a temporary impulse, or it is to follow the murderer and then rob him.
There will definitely be traces of the crime at the crime scene.
It is also unlikely to kill someone with steel nails.
Therefore, the loss of important property on the deceased is likely to be deliberately forged by the murderer.
In order to create the illusion of robbery and murder.
Of course, there is another possibility.
The deceased was engaged in the dust industry.
After the transaction was completed, the other party had no money to pay for the prostitution and had the intention to kill.
After killing the person, the victim's property was robbed.
Huh...
Let out a long breath.
Chen Yan stopped thinking.
No matter why the deceased was killed, it is only a guess now.
The most fundamental thing is to determine the specific identity of the deceased.
Looking at the time on the phone, it was already 9:30 in the evening.
There was still no news from Zhang Chaoyang and Zhao Bing.
After leaving the office, Chen Yan came to Wang Gang's office.
Hearing footsteps, Wang Gang turned around and saw that it was Chen Yan: "Captain, you are here."
"Yes," Chen Yan nodded: "How is the comparison going?"
"There is no information yet."
Although the DNA database was established very early, the information of the people entered is not very rich.
Currently, it only covers all people with criminal records.
For ordinary citizens, it is difficult to collect DNA information, and they will not deliberately enter the DNA database.
Therefore, if the perpetrator has no criminal record, it is difficult to identify the murderer through the comparison of the DNA database.
"Continue to compare, if there is good news, there will be a breakthrough in the investigation of the case..."
"Okay."
It was 11 o'clock in the evening.
Zhang Chaoyang and Zhao Bing returned to the second detective team.
In the meeting room, Chen Yan knew from the expressions of the two that the investigation was not going smoothly.
Sure enough.
"Captain Chen, the identity of the deceased has not been confirmed yet."
"We conducted a visit and investigation near the Taipingfang self-built housing area, and there were no reports of missing persons."
"We also contacted other detective teams, and there were no reports of missing persons in the past two days."
"We also contacted the detective teams of several nearby cities."
"There have been three reports of missing persons in the past two days."
"Two men and one woman. The missing woman is 52 years old, which does not match the deceased we found."
Chen Yan nodded, and then looked at Zhao Bing on the side.
"Captain Chen, my visit and investigation did not provide any particularly valuable information."
"The construction of the Taipingfang self-built housing area started three days ago."
"Due to the high noise and dust caused by the construction."
"Residents in the surrounding area rarely approach the self-built housing area at night."
"In addition, the surrounding areas are resettlement housing communities for demolished personnel, with a large number of tenants and a complex population."
"The flow of people is also very large, and it is very difficult to visit and investigate."
Chen Yan had expected this.
The self-built housing area where the deceased was found is one of the three self-built housing areas in Liancheng.
It has existed for more than 30 years.
The Taipingfang area being demolished is only a part of this self-built housing area.
Last year and the year before, large areas of self-built housing areas were demolished and turned into resettlement housing.
So both the flow of people and the complexity of personnel are very large.
"I am very clear about the difficulty of advancing the work."
"But the identity of the deceased has not been determined yet, and the investigation of the case is at a standstill."
"Chaoyang, Zhao Bing, you still have to work harder."
"We have currently determined the cause of death of the deceased, and found 4 types of DNA information from the deceased."
"But now we have not matched any results in the DNA information database."
"The determination of the identity and occupation of the deceased is related to the direction of our next investigation of the case."
"So the work of the two of you is the top priority."
After instructing Zhang Chaoyang and Zhao Bing, Chen Yan looked at the others: "Do you have any other opinions on the investigation of the case?"
This is the second case analysis meeting.
There are 36 detectives from the second detective team in the meeting room.
But no one spoke.
The main reason was that there was too little useful information about the case.
The scene was not the first crime scene, and the clues left by the murderer were very limited.
Now that the identity of the deceased has not been determined, there is no way to propose the specific direction of the next case investigation.
So the most urgent task is to determine the identity of the deceased.
"Captain..." Song Lingxuan's voice came from the edge of the conference table.
Although Song Lingxuan had just joined the company not long ago, she grew very fast.
In the trace identification team, she has gradually become a backbone.
This time, Song Lingxuan went to the scene with her master.
"I have a suggestion, I don't know if it is appropriate."
"Oh? There is nothing appropriate or inappropriate, tell me."
"Well, it's like this."
"When I was investigating the scene, I found that the clothes worn by the deceased were DR brand."
"The clothes of this brand are international luxury brands, and the price is relatively expensive."
"Most people rarely wear clothes of this brand."
"And there are very few DR brand stores in Liancheng."
"When I was shopping in the mall some time ago, I saw this kind of clothes worn by the deceased."
"It is certain that the clothes worn by the deceased are this year's new models, so I wonder if I can investigate from this aspect."
clothing?
When Chen Yan was investigating the scene, he had already noticed that the clothes worn by the deceased were of better quality.
But I really don’t know much about brand statements.
But Song Lingxuan's suggestion is very good.
When Zhang Chaoyang and others who were responsible for investigating the identity of the deceased heard this, their eyes lit up.
If what Song Lingxuan said is true, then there is a good way to determine the identity of the deceased.
By investigating the sales information of DR brand stores, it is very likely to find the deceased.
"Okay, that's a good suggestion."
Chen Yan looked at Zhang Chaoyang: "Chaoyang, tomorrow morning I will take Xiao Song with me to investigate these DR brand counters."
"yes."
This means that a ruler is shorter and an inch is longer.
Zhang Chaoyang has never been exposed to this brand of clothing before.
How can Zhang Chaoyang afford clothes that cost tens of thousands of yuan a piece?
Ordinary men rarely pay attention to news in this area.
Song Lingxuan is different, which is why the detective team is equipped with some female detectives.
It’s not just that men and women work together so they don’t get tired.
What women pay attention to is sometimes what men ignore.
…
Noon on the 18th.
Zhang Chaoyang and Song Lingxuan brought back good news.
"Team Chen, found it!"
"Xiao Song's method really works."
Zhang Chaoyang reported excitedly in the conference room: "The clothes worn by the deceased are this year's new models of the DR brand."
"Each piece of clothing sells for more than 20,000 yuan."
"We found the sales record of this dress at the DR brand counter in Pacific Department Store."
"A total of three pieces of this dress were sold this year."
Turning on the projector, Zhang Chaoyang showed the sales records to Chen Yan.
"But in the backend system of the counter, we can only find the sales records, but there is no way to find out the specific person to whom it was sold."
"Next, Xiao Song and I went to the counters of three shopping malls where this type of clothing was sold for verification."
"Three people were found to have purchased this piece of clothing, one man and two women."
"Then we retrieved the surveillance video and finally made important discoveries at the DR counter of Xidan Department Store."
"Captain Chen, look..."
When Zhang Chaoyang opened the video, it was the image of a woman leaving the DR counter.
Click.
Click the mouse and the screen pauses.
The woman in the video just turned around, and a familiar face was frozen on the projection screen.
It was the deceased.
"Finally we investigated the bank card swiping records of the deceased when he purchased clothes."
"But when the deceased purchased clothes, the bank card she used was not her own."
"It's a secondary card of a credit card. The owner of the main card is a man named Meng Jianglin."
"Meng Jianglin? Who is he?"
"We have just investigated Meng Jianglin's specific information."
Switching to the screen projection, a picture of a bald man appeared on the screen.
"Meng Jianglin, male, 52 years old, general manager of Liancheng Yuanfang Industrial Company."
good!
"Summon Meng Jianglin immediately."
"yes!"
But what is surprising is that Meng Jianglin is not in Liancheng.
The mobile phone was also turned off. The detective sent by Chen Yan did not find Meng Jianglin.
Only Meng Jianglin’s wife Zhao Ying was contacted.
"How do I know where that damn ghost has gone?"
"Since I have some money, I change women every day to support my mistress. I think he will die on the woman's belly sooner or later."
"If you really have trouble with him, go find a woman named Gu Dongmei."
"This Gu Dongmei is Meng Jianglin's health masseur. She is actually his mistress. She must know where Lao Meng is."
It turns out that Gu Dongmei was originally Zhao Ying's health masseur, but later fell in love with Meng Jianglin.
The two hooked up together.
However, it is obviously impossible to find Meng Jianglin through Gu Dongmei.
Because, as found in the population system, Gu Dongmei has a total of 36 people in China.
Comparing the ID card photos, among them, a woman named Gu Dongmei, whose ancestral home is in Guizhou Province, is the deceased!
Four hours later, the basic information about the deceased was clearly investigated.
…
meeting room.
The third security case analysis meeting.
Zhang Chaoyang began to introduce the situation.
"The deceased, Gu Dongmei, female, 25 years old, from Guizhou, Guizhou Province, came to Liancheng four years ago."
"Running a massage and health parlor, but not open to the public."
"He was originally the masseuse of Meng Jianglin's wife Zhao Ying. Later, after meeting Meng Jianglin, the two hooked up."
"She is now Meng Jianglin's mistress."
"I have a boyfriend named Wang Xiaobei, 26 years old, who is a delivery rider."
After the basic introduction, Chen Yan started the arrangement work.
"First, find out all the interpersonal relationships of the deceased Gu Dongmei."
"What friends are there, what enemies are there, are there any other close men besides Meng Jianglin, etc. I want all the detailed information about Gu Dongmei."
"Second, investigate all the whereabouts of Meng Jianglin, general manager of Yuanfang Industrial Company, in the past two days, especially the period from the 16th to the 17th."
"Third, investigate the interpersonal relationships of the deceased Gu Dongmei's boyfriend Wang Xiaobei."
His girlfriend has been missing for two days and has not yet reported the crime. Wang Xiaobei is currently suspected of committing a major crime.
"And summon Wang Xiaobei. I will interrogate Wang Xiaobei in person."
If Wang Xiaobei knew about the mistress relationship between the deceased Gu Dongmei and Meng Jianglin.
Then it is very likely that Wang Xiaobei killed in revenge.
"Fourth, compare the DNA information found in Gu Dongmei's body with Meng Jianglin, Wang Xiaobei... and Wu Guizhong who found the body and reported it to the police."
The autopsy personnel found 4 types of DNA information in the body of the deceased Gu Dongmei.
This is very abnormal.
Because from the information currently obtained, there are only two men who had an intimate relationship with Gu Dongmei.
One is her boyfriend Wang Xiaobei, and the other is her lover Meng Jianglin.
Since Gu Dongmei is Meng Jianglin's mistress, it is very likely that she had close contact with Meng Jianglin for a period of time before she was killed.
Then it is normal to detect Meng Jianglin's DNA information in Gu Dongmei.
And her boyfriend Wang Xiaobei may have had close contact with her before Gu Dongmei died.
But why were 4 types of DNA information found in her body?
Who are the other two men?
