Chapter 352: Paternity Test Report
The genius remembers the address of this site in a second: [new] the fastest update! No ads!
There are four cars and six motorcycles.
Vehicles entering and exiting Langdong Village must pass by the speed camera on the national highway near the fork in Langdong Village.
Therefore, Xie Yongfeng only needs to check the photos taken by the speed measuring system that day to confirm the information of the vehicles entering and leaving Langdong Village that day.
One of the four cars is a Rolls-Royce SUV in which you are traveling.
There is also a BMW brand off-road vehicle. I have already contacted the owner of the car. They are also going to the Valley of Ten Thousand Buddhas for fun. They will arrive later than you, and they will leave near dusk.
Chen Yan nodded.
He has an impression of this car.
Black BMW car.
The car was going up the hill when they went down.
Is it the black BMW we met? The young lady next to Chen Yan obviously also had an impression, and whispered softly in Chen Yan's ear.
Chen Yan nodded: That's the car. Remember the website m.xbequige. com
The remaining two cars are taxis in the town. We have found the owner and the renter.
One is to go to the town to see a doctor and come back to fetch the patients, and the other is to buy things in the town and send them back to the village.
No problem at all.
The six motorcycles have also been checked.
Five of the vehicles are villagers from Langdong Village,
Another one is from other villages visiting relatives in Langdong Village.
The owners of the six cars have been found, and the transcripts of the inquiries have been made.
Did the two taxis pick up anyone else when they left Langdong Village?
No, Xie Yongfeng shook his head: They all returned to Hongshui Town with empty cars.
The murderer probably didn't leave in their car.
After Xie Yongfeng finished his report, Liu Yongming looked at Chen Yan: Team Leader Chen, what do you mean...
Wait, Chen Yan frowned, wait for the analysis report of the shoe prints.
If it is confirmed that the shoe print belongs to Zhang Songlin, then we will investigate how he came to Langdong Village.
if not……
Although Chen Yan didn't say what would happen if it wasn't.
But it's really not, and that's interesting.
The motorcycle is the escape tool used by the murderer after committing the crime.
The half footprint on the cliff boulder must belong to the murderer.
So, if the footprints don't belong to Zhang Songlin, who is the murderer?
Also, where did Zhang Songlin, who has disappeared, go?
Chen Yan didn't wait too long.
An hour later, the identification report of the footprints was faxed from your city.
Team Leader Chen, this is troublesome!
Liu Yongming's face was very ugly.
Pass the report in hand to Chen Yan: The shoe prints at the scene have been determined not to belong to Zhang Songlin!
Reporting is simple.
Xieyin's shoe number is 41, while Zhang Songlin's shoe number is 43.
There is also some speculative information in the report.
The owner of the shoe print, male, should be between 170 and 180 in height.
The weight is between 65 kg and 80 kg.
Between 20 and 30 years old.
After receiving the report, Chen Yan knew that your city must have hired the most experienced appraisal experts to conduct a detailed appraisal of the shoe prints.
It is not difficult to determine the gender, height and weight of the owner from the footprint shoe prints.
However, it is very difficult to determine the approximate age range.
Sitting next to Chen Yan, Miss Yu happened to be able to see the contents of the report.
When seeing the age analysis, Miss Yu was a little uneasy.
This...you can analyze the age from the shoe prints?
Chen Yan smiled: Of course.
There is a scientific basis for this.
When a person is at different ages, the distance between the bones of the feet changes slightly.
Although the changes in the middle are very small, they can also be reflected in different positions of the shoe prints, with different efforts.
Some experienced appraisal experts can determine the approximate age range of the person whose footprints belong to through careful observation and analysis.
Oh……
Shen Yunyi nodded, although she didn't understand.
But it does sound plausible.
Group leader Chen, what's your suggestion next?
Chen Yan frowned slightly, and looked at Liu Yongming after thinking about it.
First, find Zhang Songlin's whereabouts.
Zhang Songlin's whereabouts are unknown now, and it is very likely that he has an important connection with Zhao Xiaomeng's shooting.
Secondly, now that Zhang Songlin has been determined not to be the murderer, who the hell is killing people with guns in Langdong Village?
When Chen Yan was in Langdong Village, he had already conducted a very detailed inspection of Wang Wanwan's off-road vehicle.
Except for the traces of Zhao Xiaomeng and Wang Wanwan riding in the car.
Chen Yan also found traces left by some other people.
It should be Wang Wanwan's driver or someone else's.
It is not realistic to want to use this to identify the suspect.
Moreover, Chen Yan had asked Xie Yongfeng to check all the speed test photos of this car on the day of the incident.
It was Wang Wanwan who was driving, and Zhao Xiaomeng was sitting in the passenger seat.
No third person was found in the car.
Of course, the speed test photos will not capture the second row of the car.
But the footage from the checkpoint is different.
In your province, there are security checks at some intersections, and all windows need to be lowered.
And there was surveillance video, but no one was found in the third row.
Three hours later.
Chen Yan, Liu Yongming and others left County L and returned to Guizhou.
Your City Police Department.
After Zhang Songlin disappeared, Liu Yongming immediately arranged for detectives to search Zhang Songlin's home and shooting range.
We found this at Zhang Songlin's house. Liu Yuming handed the two reports to Chen Yan.
Opening the report, Chen Yan was slightly taken aback.
Paternity test report?
Liu Yongming nodded: Yes, it is the paternity test report.
Zhang Songlin and Zhao Xiaomeng have two children together.
One is eight years old and the other is just three years old.
A week ago, that is, four days before the incident, Zhang Songlin and his two children took a paternity test.
As a result, the two children have no parent-child relationship with Zhang Songlin.
This is also one of the important basis for us to judge Zhang Songlin as the murderer.
Chen Yan read the report carefully.
Huh?
Chen Yan who opened the report was slightly surprised.
There is a big difference in the genetic matching rate between the two children and Zhang Songlin.
The index to identify whether the child and the father are related by blood is called the parentage index.
Only when the parentage index is greater than 99.99% can it be determined that the father and the child are related by blood.
In the general paternity test report, it will be marked at the end whether it supports the blood relationship between the father and the child.
This is the general conclusive evaluation.
But the data in the entire appraisal report actually has many other items.
Chen Yan has specialization in trace identification skills rewarded by the system.
Therefore, Chen Yan was very clear about the various data in the appraisal report.
In the two appraisal reports, the parentage index of the two children and Zhang Songlin are not the same.
That's where it gets interesting.
If the father of two children is the same person, then their parentage index should be the same as that of a stranger.
Or with only a very small difference.
However, the parental index of Zhang Songlin and his two children is very different.
In other words, it is very likely that the two children are not the same father.
Not only are Zhao Xiaomeng's two children not Zhang Songlin's, they are not even the same man's.
Group leader Liu, I suggest comparing the DNA information of Zhao Xiaomeng's two children.
At the same time, do a DNA paternity test with Wang Wanwan.
After receiving the report from Chen Yan, Liu Yongming frowned slightly.
Liu Yongming understood what it meant by asking the two children to do a DNA comparison with Wang Wanwan.
It is nothing more than to determine whether these two children belong to Wang Wanwan.
But why do two children have to do DNA information comparison at the same time?
Liu Yongming is also an old detective, after a little thought, he understood what Chen Yan meant: Group Leader Chen...you mean these two children...
Maybe they are not all Wang Wanwan's children?
Chen Yan nodded: From the DNA paternity test reports of these two children and Zhang Songlin.
Two children are certainly not one father.
Of course there is also a probability problem here.
So only after a paternity test can we draw conclusions.
Liu Yongming nodded: Okay, I will arrange it now.
Next, Chen Yan took Shen Yunyi to three places.
The respective residences of Zhang Songlin and Wang Wanwan, and the shooting range opened by Zhang Songlin.
Chen Yan already had a guess in his mind.
Although the murderer is not Zhang Songlin, it is very likely that he is related to Zhang Songlin.
Because the firearms used by the murderer cannot be obtained out of thin air.
Liu Yongming and others found firearm assembly parts in Zhang Songlin's home and shooting range.
There is a high probability that it is the source of the murderer's assembly of firearms.
Besides Zhang Songlin, the people who can touch the assembly parts of these firearms must be the people he trusts the most.
No. 18 Qingnian Road, Rose Garden Community.
Wang Wanwan has a villa in this community.
Entering the villa, Chen Yan immediately opened the olfactory gene lock.
