Chapter 353: Paternity Test Report (Please Vote for More!)

There are four cars and six motorcycles in total.

Vehicles entering and leaving Langdong Village must pass the speed camera on the national highway near the fork in the road near Langdong Village.

Therefore, Xie Yongfeng only needs to check the photos taken by the speed camera system on that day to confirm the information of vehicles entering and leaving Langdong Village on that day.

"One of the four cars is the Rolls-Royce SUV you are riding in."

"The other one is a BMW brand SUV. I have contacted the owner. They are also going to Wanfo Valley for fun. They went later than you and left near dusk."

Chen Yan nodded.

He remembered this car.

A black BMW.

When they went down the mountain, this car was going up the mountain.

"Is it the black BMW we met?" The little sister next to Chen Yan obviously also remembered it and whispered to Chen Yan softly.

Chen Yan nodded: "That's the car."

"The remaining two cars are taxis in the town. We have found the owners and the people who rented them."

"One was a patient who went to the town for medical treatment and brought back, and the other was a person who bought things in the town and sent them back to the village."

"No problem."

"The six motorcycles have also been checked."

"Five of the cars belong to villagers in Langdong Village, and one belongs to relatives from other villages who came to Langdong Village to visit."

"The six owners have been found and their statements have been taken."

"Did the two taxis carry other people when they left Langdong Village?"

"No," Xie Yongfeng shook his head: "They all returned to Hongshui Town empty."

"The murderer should not have left 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 and see the analysis report of the shoe prints."

"If it is confirmed that the shoe prints belong to Zhang Songlin, then we will investigate how he came to Langdong Village."

"If not..."

Although Chen Yan did not say what would happen if it was not.

But if it really was not, it would be interesting.

The motorcycle was the escape tool used by the murderer after committing the crime.

The half footprint on the huge rock on the cliff must belong to the murderer.

So, if the footprint does not belong to Zhang Songlin, who is the murderer?

Also, where did Zhang Songlin, who has disappeared, go?

Chen Yan did not wait too long.

An hour later, the identification report of the footprint was faxed from Gui City.

"Team Leader Chen, this is trouble!"

Liu Yongming's face was very ugly.

He handed the report in his hand to Chen Yan: "The shoe prints at the scene have been confirmed not to belong to Zhang Songlin!"

The report is very simple.

The shoe number of the shoe print is 41, and the shoe number of Zhang Songlin is 43.

There are some speculative information in the report.

The owner of the shoe print, male, should be between 170 and 180 cm tall.

The weight is between 65 kg and 80 kg.

The age is between 20 and 30 years old.

After getting the report, Chen Yan knew that Gui City must have found the most experienced identification expert to conduct a detailed identification of the shoe print.

It is not difficult to determine the gender, height and weight of the owner from the footprints.

However, it is very difficult to determine the approximate age range.

The little lady sitting next to Chen Yan was able to glimpse the content of the report.

When she saw the age analysis, the little lady was a little uneasy.

"This... can the age be analyzed from the shoe prints?"

Chen Yan smiled: "Of course."

"There is a scientific basis for this."

"At different ages, the distance between the foot bones of a person 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 forces."

"Some experienced identification experts can determine the approximate age range of the owner of the footprints through careful observation and analysis."

Oh...

Shen Yunyi nodded, although he didn't understand it.

But it still sounded a little reasonable.

"Team leader Chen, what suggestions do you have next?"

Chen Yan frowned slightly, thought about it and looked at Liu Yongming.

"First, we need to 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 case."

"Second, it has been confirmed that Zhang Songlin is not the murderer, so who is the one who killed people with a gun in Langdong Village?"

When Chen Yan was in Langdong Village, he had conducted a very detailed inspection of the off-road vehicle driven by Wang Baiwan.

In addition to the traces of Zhao Xiaomeng and Wang Baiwan in the car.

Chen Yan also found traces left by some other people.

It should be Wang Baiwan's driver or someone else.

It is not realistic to identify the suspect through this point.

And Chen Yan has asked Xie Yongfeng to check all the speed cameras of this car on the day of the incident.

It was Wang Baiwan who was driving, and Zhao Xiaomeng was sitting in the co-pilot seat.

No third person was found in the car.

Of course, the speed camera will not capture the situation in the second row of the car.

But the video at the checkpoint is different.

In your province, some intersections have security checks, and all windows need to be lowered.

And there is surveillance video, but no one was found in the third row.

Three hours later.

Chen Yan, Liu Yongming and others left L County and returned to Gui City.

Gui City Detective Team.

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 home." Liu Yuming handed two reports to Chen Yan.

Chen Yan was slightly startled when he opened the report.

"Paternity test report?"

Liu Yongming nodded: "Yes, it is the paternity test report."

"Zhang Songlin and Zhao Xiaomeng have two children in total."

"One is eight years old and the other is just three years old."

"A week ago, four days before the incident, Zhang Songlin and his two children did a paternity test."

"As a result, both children have no parent-child relationship with Zhang Songlin."

"This is also one of the important bases for us to judge that Zhang Songlin is the murderer at the time."

Chen Yan carefully read the report.

Huh?

Chen Yan was slightly surprised when he opened the report.

The genetic matching rate between the two children and Zhang Songlin is quite different.

The indicator for determining whether a child and his 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 general, the parentage test report will be marked at the end to indicate whether the father and the child are related by blood.

This is the general conclusive evaluation.

But there are actually many other items in the data of the entire identification report.

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

So Chen Yan is very clear about the various data in the identification report.

In the two identification reports, the parentage index of the two children and Zhang Songlin is not the same.

This is interesting.

If the father of the two children is the same person, then their parentage index with a stranger should be the same.

Or there is only a very small difference.

But the parentage index of Zhang Songlin and his two children is very different.

In other words, the two children are very likely not from the same father.

Zhao Xiaomeng's two children are not only not Zhang Songlin's, but also not from the same man.

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

"Do a DNA paternity test with Wang Baiwan at the same time."

Liu Yongming frowned slightly after taking the report from Chen Yan.

Liu Yongming understood what it meant to let the two children do a DNA comparison with Wang Baiwan.

It is nothing more than to determine whether the two children belong to Wang Baiwan.

But why do we have to do a DNA information comparison for the two children at the same time?

Liu Yongming is also an old detective. After a little thought, he understood what Chen Yan meant: "Team Leader Chen...you mean these two children..."

"Maybe they are not all Wang Baiwan's children?"

Chen Yan nodded: "From the DNA paternity test report of these two children and Zhang Songlin."

"The two children definitely do not have the same father."

"Of course there is also a probability problem here."

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

Liu Yongming nodded: "Okay, I'll arrange it now."

Next, Chen Yan took Shen Yunyi to three places.

Zhang Songlin and Wang Baiwan's respective residences, as well as the shooting range opened by Zhang Songlin.

Chen Yan actually 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 guns used by the murderer cannot be obtained out of thin air.

Liu Yongming and others found gun assembly parts in Zhang Songlin's home and shooting range.

It is likely that the source of the guns assembled by the murderer.

And the person who can access these gun assembly parts, in addition to Zhang Songlin, must be the person he trusts the most.

No. 18 Qingnian Road, Rose Garden Community.

Wang Baiwan has a villa in this community.

Entering the villa, Chen Yan immediately opened the olfactory gene lock.
