Chen Yan was slightly surprised when he opened the report.

There is a big difference in the genetic matching rates between the two children and Zhang Songlin.

The index used to identify whether a child is related to his father is called the paternity index.

Only when the paternity index is greater than 99.99% can it be determined that the father and the child are related by blood.

A general paternity test report will indicate at the end whether it supports the blood relationship between the father and the child.

This is the general concluding evaluation.

But the data in the entire appraisal report actually contains many other items.

Chen Yan has the trace identification skill specialization rewarded by the system.

Therefore, Chen Yan is very clear about the various data in the appraisal report.

In the two appraisal reports, the parental rights index of the two children and Zhang Songlin were different.

This is interesting.

If the father of two children is the same person, then their paternity index should be the same as that of a stranger.

Or there is only a very small difference.

But the gap in parental authority between Zhang Songlin and his two children is very large.

In other words, it is very possible that these two children do not have the same father.

Zhao Xiaomeng's two children are not only not Zhang Songlin's, they are not even the children of the same man.

"Team Leader Liu, I suggest that the DNA information of Zhao Xiaomeng's two children be compared."

"At the same time, I will do a DNA paternity test with Wang Wanwan."

Taking the report from Chen Yan's hand, Liu Yongming frowned slightly.

Liu Yongming understood what it meant by asking the two children to do DNA comparison with Wang Wanwan.

It's just to determine whether these two children belong to Wang Wanwan.

But why should two children have their DNA information compared at the same time?

Liu Yongming was also an old detective. After thinking about it for a moment, he understood what Chen Yan meant: "Team Leader Chen... you mean these two children..."

"Is it possible that not all of them are Wang Wanwan's children?"

Chen Yan nodded: "Judging from the DNA paternity test reports of these two children and Zhang Songlin."

"Two children are definitely not the same father."

"Of course there is also a question of probability here."

"So we can only draw a conclusion after doing a paternity test."

Liu Yongming nodded: "Okay, I'll make arrangements right now."

Next, Chen Yan took Shen Yunyi to three places.

The respective residences of Zhang Songlin and Wang Wanwan, as well as the shooting range opened by Zhang Songlin.

Chen Yan actually already had a guess in his mind.

Although the murderer is not Zhang Songlin, he is very likely to be related to Zhang Songlin.

Because the firearm used by the murderer could not be obtained out of thin air.

Liu Yongming and others found firearm assembly parts at Zhang Songlin's home and shooting range.

There is a high probability that this is where the murderer assembled his firearms.

Besides Zhang Songlin, the person who has access to these firearm assembly parts must be the person he trusts the most.

No. 18 Qingnian Road, Rose Garden Community.
