Chapter 124 SNP Analysis!



Dajing Airport, second floor of the terminal!

After Shao Ming finished speaking, he looked forward to seeing panic on "Wu Linjie's" face.

But he was clearly disappointed.

"Wu Linjie", who had been under control, did not show any panic on his face when facing the special police officers who surrounded him twice, and the passers-by who were watching from a distance and pointing at him from time to time.

Only anger and helplessness:

"What Captain Lei?

Isn’t that my brother?

Wasn't he brutally murdered a few days ago?

I'm his twin brother!

Did you recognize the wrong person?

No, my brother is dead. His body is in the autopsy room. Why are you looking for him?

You should catch the murderer!"

Obviously, "Wu Linjie" is as stubborn as Captain Zheng was at the beginning and refuses to plead guilty.

Shao Ming sneered, wanting to expose his tricks directly.

But as more and more people gathered around to watch the fun, many of them took out their mobile phones and started taking photos and videos.

Obviously, this is not the place to "chat".

He asked his men to deal with the scene and then take "Wu Linjie" away.

Along the way, "Wu Linjie" kept claiming that he was really not Lei Ping'an.

He said he had some things to attend to when he returned to Australia and asked the police not to delay his flight.

But the special police officers ignored them all.

After seeing "Wu Linjie" being taken into the police car, Shao Ming finally breathed a sigh of relief.

As he walked towards the co-pilot seat, he looked at Shen Ting beside him and said with a smile:

"Advisor Shen, the Punisher case should be concluded now!

There won't be any more twists and turns like the one that happened to Zheng Yuanqiao before, right?

"Don't worry, Shao. It won't happen."

Chen Ting also laughed and said, "The basis for arresting 'Wu Linjie' this time is the trace left by the Punisher in Zhenwu Hall. There is no mistake."

"Indeed!"

Shao Ming nodded repeatedly:

"I'll tell the security bureau the news of the successful arrest so he can rest assured."

He took out his cell phone and contacted Wei Lianbing.

Upon learning that "Wu Linjie" was successfully arrested, Wei Lianbing naturally breathed a sigh of relief.

However, he also told Shao Ming some bad news.

When Shao Ming hung up the phone, his brows were tightly furrowed, and there was visible doubt in his eyes.

Shen Ting was actually curious:

"What's wrong? Is there any new discovery in the bureau?"

Shao Ming nodded:

"Previously, the DNA laboratory conducted DNA testing on the sixth case, the body of 'Lei Ping'an' and his son from the Viper Hell, using STR analysis.

STR analysis is not effective for identical twins.

Therefore, the DNA laboratory used more advanced identification techniques such as SNP analysis on the deceased in Giant View in the valley and Lei Ping'an's son.

Normally, if the giant corpse is really Wu Linjie.

Using these more advanced identification techniques, there will be slight differences in the DNA between that and Lei Ping'an's son.

But the identification result is not like this!

Even with the most advanced DNA testing technology, the results remained unchanged, confirming the father-son relationship.

ah?

Shen Ting was stunned for a moment.

Obviously, I didn't expect this result.

DNA laboratories previously used STR analysis, which is short tandem repeat analysis.

Short tandem repeat sequences are core units in gene sequences that consist of 2-6 bases and are repeated multiple times in tandem to form a gene sequence.

This repetitive sequence is widely present in human DNA.

Moreover, the number of repetitions of the same STR locus in different individuals is specific.

By testing multiple STR loci, if the number of repetitions is exactly the same, it can be determined that it is the same person.

Children will inherit the STR locus characteristics of their parents, which can naturally be used for paternity testing.

STR identification has high sensitivity, costs only two or three hundred yuan, and has a fast detection speed. It is widely used in the field of criminal investigation around the world.

There are of course disadvantages, as in this case, it is impossible to distinguish between identical twins.

Because identical twins have the same number of STR loci repeats.

Similarly, it is impossible to tell the difference between identical twins.

DNA identification has been developed for so many years, and naturally there are other more accurate methods.

For example, the SNP analysis currently used in the laboratory can distinguish between identical twins and parent-child relationships.

The most common type of variation in the human genome is single base variation, or SNP.

Even identical twins have different SNPs.

Moreover, this mutation will be passed on to the next generation through germ cells.

Therefore, there is definitely no problem with the DNA laboratory using the SNP identification results.

Lei Ping'an's son and the giant looking at the corpse in the valley must be father and son.

From the experimenter's point of view, there are only two possibilities.

First, Shen Ting was wrong.

Lei Ping'an is really dead.

The giant looking at the corpse was Lei Ping'an.

And the person in the police car now is Wu Linjie himself.

Then there is the second possibility -

"Oh my god, there's an unexpected gain~~~"

And Shen Ting was extremely certain that the person in the police car was definitely Lei Ping'an.

His physical characteristics are absolutely impossible to fake.

So there is no doubt that the body in the valley must be Wu Linjie.

That means there is something going on between Lei Ping'an's wife and his brother!

this……

?(?–?)?

Shen Ting's expression was surprised and a little surprised.

The fact that the case has made such progress at this stage was beyond his expectations.

As the police car started, "Wu Linjie" was quickly taken back to the Miyun District Police Station.

The interrogation will soon begin!

However, just like Captain Zheng before him, "Wu Linjie" neither admitted that he was the punisher.

He also did not admit that he was Lei Ping'an, and insisted that he was Wu Linjie.

To prove his identity, he also showed his tattoo to the interrogator.

"Tattoos can be forged at any time.

But human characteristics, that's not acceptable."

Shen Ting didn't expect "Wu Linjie" to be so stubborn.

The key point is that after returning to the police station, he shared Wu Linjie's information.

It was confirmed that his body had slight differences in certain features from Lei Ping'an, the Punisher.

"So, the 'Wu Linjie' in the interrogation room must be Lei Ping'an.

Let’s wait for the identification results from the DNA laboratory!

Once the DNA test results come out, no matter how he tries to argue, it will be useless."

The DNA laboratory has been applied for, and a blood sample was taken from Lei Ping'an during the unified physical examination at the unit in the first half of the year.

Using SNP analysis, the identity of "Wu Linjie" can be confirmed quickly in a technical field that is acceptable to everyone.

Thinking about it, Shen Ting's scalp suddenly felt numb.

"Wait, it seems like I've been tricked by the Punisher again!"
