"It's so hard!"

After sending the rope to Lu Mantong, the other party shook his head after seeing it.

Compared to the ropes used to bind the stones on the corpses, the ones found from the water, although they are in slightly better condition, are really limited.

If you want to extract effective information from above, as Lu Mantong said, it is difficult, it is really difficult!

Lu Mantong is still very young, and he still needs to continue to learn and practice some knowledge in the field of forensic science.

In fact, Sister Lu can't do this, Min Xue has some ideas, but even if you say it, everyone can't believe it.

You are a criminal policeman who is engaged in front-line criminal investigation work, can you be more awesome than a professional forensic doctor to conduct physical evidence examination?

Why don't you go to heaven!

Fortunately, Min Xue doesn't necessarily have to get started, there is always more than one forensic doctor, and what Lu Mantong can't do doesn't mean that other forensic doctors can't do it.

When encountering difficult problems, Lu Mantong took the initiative to invite Huang Shi, the chief forensic doctor of the Municipal Bureau.

However, even though he has been engaged in forensic work for decades, facing the rope in front of him, Huang Zhi couldn't help frowning.

"All I can say is, try it and don't dare to be sure of the result. ”

After all, it is better to try than not to start, and out of the conservative concept of the Chinese people, Huang Zhi's statement means that the success rate should not be very low.

Lu Mantong showed admiration when he heard this, and took the initiative to ask to be an assistant.

Huang Shi did not refuse, and he is not the kind of person who cherishes himself with a broom.

Forensic resources are already scarce, and Huang Shi often feels that he lacks skills, if he can cultivate more outstanding juniors, why not?

When he came out after being locked in the laboratory for a day and night, Huang Zhi's brows stretched slightly, and it seemed that the results were good.

Sure enough, Huang Zhi said to Min Xue, who rushed to hear the news, "Xiao Lu and I successfully extracted a small amount of skin fragments from one of the ropes, as well as a few fingerprints. ”

Skin?

Fingerprint?

Min Xue's eyes lit up when he heard this, which was really unexpected. The result was already much better than he expected, but he didn't expect that a small rope would hide so much information!

With these clues, the murderer is still on paper?

Seeing this, Lu Mantong, who was accompanying him, said, "Don't be too happy, I have good news and bad news here, which one do you want to listen to first?"

“......”

This sentence pattern...

Anyway, the girl usually has time to watch TV?

complained and complained, Min Xue still went on, "There has been too much bad news recently, let's listen to it first." ”

Indeed, the early stage of the case was full of all kinds of irregularities and made people's heads big.

Later, two corpses, one large and one small, were salvaged one after another, and the whole group seemed to be filled with negative emotions, no wonder Min Xue wanted to hear some good news.

Hearing this, Lu Mantong took out a piece of paper with fingerprints and handed it to Min Xue.

"The good news is that we have found the owner of several fingerprints extracted from the rope, it is Xiong Feiyu!"

！

What could be better news than this?

Doesn't this mean that the police already have pointing evidence?!

Xiong Feiyu, he is undoubtedly the murderer!

Of course, this is just that, Min Xue is not so optimistic, he has not lost his memory, and he will not forget that there is bad news from Lu Mantong's side.

Without waiting for Lu Mantong to speak, Huang Zhi spoke first, "The bad news is for me, an old guy, to do it for you, because there is too little dander extracted from the rope, we can't do DNA testing." ”

Afraid that Min Xue didn't understand, Lu Mantong also explained again, "So theoretically, we can't conclude that the rope once tied the deceased Mo Feng." ”

！！！

It's really a twist and turn, but it's not a bright flower.

Of course, Min Xue understood what Huang Zhi and Lu Mantong meant, this is a very simple logic, what is missing now is a causal relationship that can connect Xiong Feiyu and Mo Feng's death.

To put it bluntly, the most direct way to obtain exclusive evidence is to identify the dander DNA extracted from the rope by Huang Zhi.

If the appraisal result is Mo Feng, then Xiong Feiyu will be irrefutable.

It's just that the problem now is that the dander extracted is too small to be detected.

If we can't find other groundbreaking evidence, can we only hope for future technological advances?

Just like in the era when there was no DNA technology, there were not a few people who kept physical evidence for a long time and solved cases today?

No!

At least Min Xue didn't want to wait that long!

Putting the paper in his hand back on the table, Min Xue looked at the two people opposite and asked, "PCR amplification technology is not good either?"

The so-called PCR amplification technology can be amplified through a small amount of DNA to achieve the detection amount.

"Do you know a lot? Team Min has specialized in research?" Huang Shi said in surprise when he heard this.

Although because of the popularity of film and television works, the public is no stranger to DNA, but it is only superficial. People who can remember the Chinese term DNA are already quite good, but when it comes to the various technologies applied in it, not professionals are absolutely blind.

Min Xue touched his nose, "After a little research, the class has an axe." ”

Although Huang Shi had an accident, he did not delve into it, "Of course this technology can be used, but it is too difficult to operate, because the dandruff tissue extracted this time is too small..."

Listen to the sound of the strings and know the elegance.

Min Xue suddenly, it seems that it is not that the amount of dander is not enough, but that it is a little hanging. The slightest mistake or unforeseen accident during the operation will destroy the sample and there will be no chance of remediation.

The fault tolerance rate is too low!

Even Huang Zhi, the chief forensic doctor, didn't dare to do it easily!

Min Xue took the relevant reports and materials and looked at them.

Huang Zhi didn't care, only the captain of the criminal police was unwilling, but a layman, even if he looked at it again, he could still see that a flower could not come?

Lu Mantong saw Min Xue looking at the report and materials for a long time, and couldn't help but propose, "Or, let's try to find an expert in the department?"

This is a bit offensive, our chief is still here!

Fortunately, Huang Zhi is not the kind of person who is cautious, "You can give it a try, I have always admired several national players in the ministry, especially Lu Chaozong Lu Lao, the top expert of the republic, but it's a pity that the fate is saved." ”

"It should be quite difficult to make an invitation, right?" Min Xue finally put down the information in his hand.

It's not that the forensic shelf above is large, but because there are not only many cases in the ministry, but they are basically national cases, which have a wide impact and are extremely bad in nature.

The experts are flying to Nanyun today and going to Ganshan tomorrow, and if they want to invite people, it is expected that it will be a few months older in the best case, after all, the case of the magic capital is not quite qualified.

Lu Mantong opened his mouth and wanted to say something, but in the end he didn't say it.

Huang Shi nodded approvingly, not to mention the experts in the ministry, even if it was him, he happened to be busy with a big case and was about to go to another case, if it wasn't for Lu Mantong's invitations several times, he wouldn't have had time to come over at all.

The case seems to have fallen into an embarrassing situation again, and it cannot be up and down. There is no conclusive evidence to arrest someone, what if in the long wait, the suspect runs away?

Slowly swiping his fingers over the desktop report, Min Xue suddenly said, "If I say I can do it, will you think I'm crazy?"

“......”
