Chapter 369: Locking Identity Alyssa
, on the day of the 100th blind date, arrest the blind date partner
Things are often comedic, and when you want it to be, it never does.
It comes naturally when you don't expect it.
The DNA information extracted from the bones found in the cemetery was compared with the DNA database, and a major discovery was made.
In Liu Qingshan's office, Chen Yan and Liu Qingshan are discussing the case.
The detective who was in charge of comparing the DNA information of the bones knocked on the door with an excited expression on his face.
Team Liu, Team Chen, the comparison of the DNA information of the bones has won!
After finishing speaking, the young man hurriedly handed the report in his hand to Liu Qingshan.
bingo?
When Chen Yan heard the young man's words, he raised his head with a slightly astonished expression.
Although Chen Yan has been in the police for a relatively short period of time, it has only been more than a year now, but he has investigated and handled many cases, and all of them are major cases.
Basically every case, as long as it involves DNA information identification, will be compared in the DNA information database.
But so many times, there has never been a successful comparison.
The same is true for Liu Qingshan, the expression on his face is even more astonished.
How many years has he been a detective.
Over the years, what I have experienced and what I have heard counts.
In the DNA information database, the DNA information of the victim was compared, not to mention the first time, it could be checked with one hand.
As a result, he was bumped into by himself now?
The young man in charge of comparing the DNA information also 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 database.
This means that the investigation of the case has made significant progress.
In any homicide case, as long as the identity information of the deceased can be determined, it is equivalent to half of the detection of the case has been completed.
Liu Qingshan hurriedly took the report from the young man.
Read it carefully.
But only a moment later, Liu Qingshan frowned slightly, and then reported the comparison 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 strange?
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 the DNA information comparison: Are you sure there is no error in the DNA information comparison result?
The young man nodded affirmatively: Team 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 he couldn't even believe it.
The victim's name is Alyssa, a native of the beautiful country.
Five years ago, Alisa came to Huaguo from the beautiful country, and entered the country through the capital.
This Alisa's DNA information was collected in the beautiful country. When entering the country, because of the need to verify her identity, the relevant information was entered into our system.
Chen Yan nodded.
This is also caused by the new situation changes in recent years.
In the past 20 to 30 years, many foreigners have entered and lived in China from abroad.
Among them, many people committed crimes in China.
And according to the comparative data,
The proportion of crimes committed by foreigners in China is much higher than that of locals in China.
Therefore, foreigners who have entered the country in recent years will leave their DNA information in the DNA system.
Looking at the victim information report in his hand, Chen Yan looked at Liu Qingshan: Captain Liu, let's hold another case analysis meeting.
Okay, I'll organize the meeting right now!
Boom boom boom!
Before Liu Qingshan left the office, there was another knock on the door.
Liu Qingshan looked at the young man who was reporting, the other party understood and nodded to open the door.
It's a 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: It's just a matter of time to report together at the case analysis meeting.
meeting room.
In addition to Chen Yan and Liu Qingshan, Zhang Chaoyang, Wang Gang, Zhao Bing and others also attended the meeting.
Liu Qingshan glanced at Chen Yan, who nodded, indicating that the meeting could begin.
Let's start a case analysis meeting.
First, Comrade Xiao Hu, please introduce the results of the comparison of the DNA information of the deceased.
Xiao Hu is the guy who just reported the results of Alisa's DNA comparison to Chen Yan and Liu Qingshan.
Yes, Team Liu.
Xiao Hu turned on the projector and began to report: By analyzing the genetic material on the skeleton, we obtained the victim's DNA information.
We first performed a comparison in the DNA database of missing persons, but no comparison results were found.
Later, a comparison was made in the national population information DNA database, and when it was compared to the sub-database of overseas immigrants, the comparison was successful.
The deceased, Alyssa, was a beautiful Chinese, 24 years old, 168cm in height, and entered the country from the capital five years ago.
In fact, this is also the reason why Chen Yan and Liu Qingshan were surprised.
Although Alisa is a beautiful Chinese, her ethnicity is Chinese.
He is of yellow race, not of white race.
Therefore, when analyzing the bones, Chen Yan did not think that the victim was a foreigner.
After all, the skeleton difference between yellow race and white race is very big.
In particular, the cheekbones, lower frontal bones, nasal bones, and pelvic bones all have large differences.
Even tibia, hand bones, etc., can make racial judgments.
But the other party is a foreigner of Chinese descent, so naturally he does not have these characteristics of Caucasian bones.
What was the reason for Alisa 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.
Alisa's career in the beautiful country is a chef.
The reason for entry is work!
Occupation turned out to be a chef?
Chen Yan's mind suddenly flashed 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 eyebrows.
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 that's all the information we have so far.
Chen Yan nodded and stopped talking.
Liu Qingshan on the side continued to chair the meeting.
Trace identification room, report the test results of the organic matter in the tomb.
yes!
We have carried out meticulous testing of the organic residues in the cemetery.
A large number of proteinaceous putrefaction deposits were found.
From the results of this analysis, it can basically be concluded that when the corpse entered the tomb, it was not a simple skeleton, but a complete corpse.
The decay of the corpse takes time.
But after the corpse is corrupted, it will not disappear completely without leaving any traces.
The composition of the human body is very complex, but there are only two types of skin and subcutaneous tissue.
fat and protein.
There are many types of human body fat and protein, and some sediments will be left after decomposition, especially in a closed space.
The determination of this result also locked the button clues found in the deceased's mouth.
The possibility of the murderer leaving the buttons was ruled out.
The button should be the directional clue left by the victim.
As for the murderer framing...
It's possible, but not likely.
Because judging from the clues found at the scene and the current analysis, framing does not conform to normal thinking logic!
