Chapter 370 Locking the Identity of Alyssa
Things tend to be comical and just when you want it to, it never does.
When you have no hope for it, it will appear naturally.
The DNA information extracted from the skeletons found in the cemetery was compared with the DNA information database, and a major discovery was made.
In Liu Qingshan's office, Chen Yan and Liu Qingshan were discussing the case.
The detective responsible for comparing the DNA information of the skeleton knocked on the door with an excited expression on his face.
"Team Liu and Team Chen, the DNA information of the skeleton was compared, and they were successful!"
After saying that, the two young men hurriedly handed the report in their hands to Liu Qingshan.
bingo?
When Chen Yan heard what the young man said, he raised his head and looked slightly surprised.
Although Chen Yan has been in the police for a relatively short time, only more than a year now, he has investigated many cases, and they are all major and important cases.
Basically every case involving DNA information identification will be compared in the DNA information database.
But after so many times, the comparison has never been successful.
The same was true for Liu Qingshan, with an even more stunned expression on his face.
How many years has he been working as a detective?
Over the years, I have experienced and heard everything.
In the DNA information database, the victim's DNA information was compared. Not to mention the first time, it could be checked with just one hand.
As a result, he is now being bumped into?
The young man in charge of comparing DNA information became more and more excited as he talked. Everyone was very excited to be able to compare the victim's DNA information in the DNA information database.
This means that significant progress has been made in the investigation of the case.
In any homicide case, as long as the identity of the deceased can be determined, it is equivalent to half of the case being solved.
Liu Qingshan hurriedly took the report handed over by the young man.
Read it carefully.
But just a moment later, Liu Qingshan frowned slightly, and then reported the comparative information in his hand to Chen Yan.
Chen Yan naturally noticed the change in Liu Qingshan's expression.
Now that the victim's identity information has been determined, it will be of great benefit to the investigation of the case. Why is Liu Qingshan's expression so weird?
After receiving the report, Chen Yan looked at the information above.
"Alyssa?"
The victim turned out to be a foreigner.
Chen Yan raised his head and looked at the young man in charge of DNA information comparison: "Are you sure there are no errors in the DNA information comparison results?"
The young man nodded affirmatively: "Captain Chen, don't worry, there is absolutely nothing wrong. I checked it three times."
Of course the young man knew why Chen Yan and Liu Qingshan were a little surprised. He was also a little surprised when he saw the comparison results just now, and even couldn't believe it.
"The victim's name is Alyssa, and she is from a beautiful country."
"Five years ago, Alyssa came to China from the beautiful country and entered the country from the capital."
"This Alyssa's DNA information was collected in the beautiful country. When entering the country, because it was necessary to verify the identity, the relevant information was entered into our system."
Chen Yan nodded.
This is also caused by new situation changes in recent years.
In the past two or three decades, many foreigners have entered and lived in China from abroad.
Among them, many have committed crimes in China. …
And according to comparative data, the crime rate of foreigners in China is much higher than the crime rate of native Chinese.
Therefore, newly arrived foreigners in recent years will leave their DNA information in the DNA system.
After looking at the victim information report in his hand, Chen Yan looked at Liu Qingshan: "Team Liu, let's hold another case analysis meeting."
"Okay, I'll organize the meeting right away!"
Boom, boom, boom!
Before Liu Qingshan left the office, the knock on the door rang again.
Liu Qingshan looked at the young man who was reporting. He understood, nodded and opened the door.
It was the detective from the Trace Identification Room: "Team Liu, Team Chen, the analysis results of the organic matter in the cemetery have come out."
"Okay," Liu Qingshan nodded: "We will report together at the case analysis meeting later."
meeting room.
In addition to Chen Yan and Liu Qingshan, Zhang Chaoyang, Wang Gang, Zhao Bing and others also came to attend the meeting.
Liu Qingshan glanced at Chen Yan, who nodded, indicating that the meeting could begin.
"Let's start holding a case analysis meeting."
"First of all, please let Comrade Xiao Hu introduce the results of the DNA information comparison of the deceased."
Xiao Hu was the young man who had just reported the results of Alisa's DNA information comparison to Chen Yan and Liu Qingshan.
"Yes, Captain Liu."
Xiao Hu turned on the projector and began to report: "By analyzing the genetic material on the bones, we obtained the victim's DNA information."
"We first compared it in the DNA information database of missing persons, but no matching results were found."
"Later, a comparison was conducted in the National Population Information DNA Information Database, and when the comparison was made to the sub-database of overseas immigrants, the comparison was successful."
"The deceased, Alisa, was a beautiful Chinese-American, 24 years old, 1.6cm tall, who entered the country from Beijing five years ago."
In fact, this is why Chen Yan and Liu Qingshan were surprised.
Although Alyssa is a beautiful Chinese, her ethnicity is Chinese.
I am a yellow person, not a white person.
Therefore, when analyzing the skeleton, Chen Yan did not expect that the victim was a foreigner.
After all, there are huge differences in bones between yellow and white people.
Especially the zygomatic bones, mandibular bones, nasal bones and pelvic bones are quite different.
Even the tibia, hand bones and other aspects can be used to make racial judgments.
But the other party is a Chinese foreigner, so naturally there are no such characteristics of white people's bones.
"What was the reason for Elisa to enter China five years ago?"
"Work," Xiao Hu looked at Chen Yan: "The reason for entry marked in the entry information management system is work."
"Elisa's occupation in the United States is a chef."
The reason for entry is work!
The occupation is actually a chef?
Chen Yan's mind suddenly flashed back to his guess in the dissection room.
A slender ham slicing knife appeared in Chen Yan's mind.
Now, it seems that there is finally some clues.
Chen Yan looked at Xiao Hu again: "Is there any other information?"
Xiao Hu shook his head: "The information in the entry information management system is relatively simple, and this is all the information we have obtained so far."
Chen Yan nodded and stopped talking.
Liu Qingshan on the side continued to preside over the meeting.
"Trace Identification Room, report the test results of organic matter in the grave."
"Yes!"
"We have conducted a detailed test of the organic residues in the cemetery."
"A large amount of protein organic sediments were found."
This analysis result basically determines that when the body entered the grave, it was not just a skeleton, but a complete body.
It takes a certain amount of time for a body to be decomposed.
But after decomposition, the body will not completely disappear without leaving any traces.
The human body is very complex, but there are only two most common components of skin and subcutaneous tissue.
Fat and protein.
There are many types of human fat and protein. After decomposition, especially in a confined space, some sediment will be left.
The determination of this result also locked in the button clue found in the mouth of the deceased.
The possibility of the murderer leaving the button behind is ruled out.
The button should be the directional clue left by the victim.
As for the murderer framing...
This possibility exists, but it is not great.
Because from the clues found at the scene and the current analysis, framing does not conform to normal thinking logic!
