Chapter 579 Technical Problems

"It's too difficult!"

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

Compared with the disfigured ropes used to tie the stones on the corpse, although the few ropes found underwater are of better quality, they are really limited.

To extract effective information from above, as Lu Mantong said, it is difficult, really difficult!

After all, Lu Mantong is still very young, and some knowledge in the field of forensic science still needs to be continuously learned and practiced.

In fact, Min Xue had some ideas about what Lu Meizi couldn't do, but even if he said it, everyone wouldn't believe it.

You, a criminal policeman engaged in front-line criminal investigation work, can you be better than a professional forensic doctor when you come to conduct physical evidence inspection?
Why don't you go to heaven!

Fortunately, Min Xue didn't necessarily have to get started. There was more than one forensic doctor in the Criminal Division. If Lu Mantong couldn't do it, it didn't mean that other forensic doctors couldn't do it either.

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 working in forensic medicine for decades, Huang Shi couldn't help frowning when facing the rope in front of him.

"I can only say, try it, I can't guarantee the result."

Being able to try is better than not being able to start, and because of the conservative concept of Chinese people, Huang Shi's statement means that the success rate should not be very low.

Lu Mantong showed admiration when he heard the words, and offered to act as an assistant.

Huang Shi didn't refuse, and he wasn't the kind of person who treasured himself.

Forensic medical resources are scarce, and Huang Shichang feels that he has no skills at all. If he can cultivate more outstanding juniors, why not do it?
When he was locked in the laboratory for a day and night and then came out, Huang Shi's brows were slightly relaxed, and it seemed that the results were good.

Sure enough, Huang Shi said to Min Xuedao who came over after hearing the news, "Xiao Lu and I successfully extracted a small amount of skin debris and a few fingerprints from one of the ropes."

skin?

fingerprint?

Min Xue's eyes lit up when he heard this, which was really a surprise.The result was much better than he expected. He never thought that such a small rope could hide so much information!
With these clues, is the murderer still on paper?
Seeing this, Lu Mantong who was accompanying him said, "Don't be too happy, I have a good news and a bad news, which one do you want to hear first?"

"."

this sentence pattern
By the way, girls still have time to watch TV?It seems that work is not very busy!
To complain, Min Xue continued, "There's been too much bad news recently, so let's listen to it first."

Indeed, the early stage of the case was full of all kinds of unreasonable things, which made people feel dizzy.

Later, two corpses, one large and one small, were unbearably unbearable to look at. 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 on it and handed it to Min Xue.

"The good news is that we have found the owner of the fingerprints extracted from the rope. It is Xiong Feiyu!"

!

Could there be better news than this?

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

Xiong Feiyu is undoubtedly the murderer!
Of course, this is just a saying, Min Xue is not so optimistic, he has not lost his memory, and he will not forget that there is still bad news from Lu Mantong.

Before Lu Mantong could speak, Huang Zhi spoke first, "Let me, an old guy, do the bad news. Because the dander extracted from the rope is too little, we can't carry out DNA testing."

In case Min Xue didn't understand, Lu Mantong explained, "So in theory, we can't conclude that the rope used to bind the deceased Mo Feng."

!!!

It's really a turn of events, but it's not a bright future.

Of course Min Xue understood what Huang Shi and Lu Mantong meant. This was a very simple logic. What was missing now was a causal relationship that could 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 that Huang Shi extracted from the rope.

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

The only problem now is that the amount of flakes extracted is too small to be detectable.

If there is no other breakthrough evidence, can we only hope for future scientific and technological progress?
Just like in the era without DNA technology, the police have kept physical evidence for a long time and today there are not a few cases based on it?
Do not!
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 on the opposite side and asked, "Is the STR short tandem repeat technology not working?"

STR is a section of chromosome in the human body, and the number of repetitions is different for each person. As long as multiple STR loci are detected, individuals can be identified.

"You know a lot? Team Min has done special research?" Huang Zhi said in surprise.

Although due to the popularity of film and television works, the public is no stranger to DNA, but it is only superficial.Those who can memorize the Chinese term deoxyribonucleic acid are already quite good, but when it comes to the various technologies used in it, non-professionals are absolutely blind.

Min Xue rubbed his nose, "After a little research, the class is in trouble."

Although Huang Shi had an accident, he did not delve into it, "Of course this technique is possible, but the operation is too difficult, because the dander tissue extracted this time is really too little."

Hear the strings and know the elegance.

Min Xue suddenly realized that it wasn't that there was not enough dandruff, but that it was a little overhanging.As long as there is a slight mistake in the operation process, or any unexpected accident occurs, the sample will be destroyed, and there is no chance of recovery.

The fault tolerance rate is too low!

Even Huang Shi, the chief forensic doctor, did not dare to do it easily!

Min Xue took relevant reports and materials and read them.

Huang Shi didn't take it seriously, he just thought that the captain of the criminal police was not reconciled, but a layman, even if he looked at it again, could he still see if a flower was coming?
Seeing Min Xue staring at the report and materials for a long time, Lu Mantong couldn't help but suggest, "Why don't we try to find experts from the Ministry?"

This is a bit offensive, our chief is still here!
Fortunately, Huang Shi is not the narrow-minded person, "You can give it a try. I have always admired several national players in the Ministry, especially Lu Chaozong Lu Lao, a top expert in the Republic. It's a pity that the fate is limited."

"It should be difficult to invite, right?" Min Xue finally put down the documents in his hand.

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

The experts flew to Nanyun today and went to Ganshan tomorrow. If they wanted to invite someone, they would probably be a few months older at best. After all, the case in Shanghai was not qualified enough.

Lu Mantong opened his mouth, wanting to say something, but in the end he couldn't say it.

Huang Shi nodded in agreement, not to mention the experts in the ministry, even he just happened to be busy with a big case and was about to go to another case, if it wasn't for Lu Mantong's several sincere invitations, he would have no time to come here .

The case seems to have fallen into an embarrassing situation again, with no ups and downs.It is impossible to arrest people without conclusive evidence. What if the suspect runs away during the long wait?
Flicking his finger slowly across the desktop report, Min Xue suddenly said, "If I say I can do it, will you think I'm crazy?"

"."
