Chapter 652: Extraction

Zhang Fa frowned and thought for a while, and said, "Listen to him, the big plan, now that something is wrong, it seems normal to have an investigation team to investigate the whole thing." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Wu Yingfan waved his hand and said, "No, you still don't understand what I mean, I mean Chief Ouyang is a little, how can you say it...... Blatantly blatant. Look at it, except for the time being too timely, I didn't feel polite at all, and I was directly confronting the bureau. Finally, he said that he was waiting for the investigation team to investigate. It really feels ready, and it's getting to the point where it's not much to hide. ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Sun Guoxin still had that uncertain look, snuffed out the cigarette, and finally said, "No matter what, now no matter what, the soldiers will block it." Don't get caught by anyone with pigtails. Keqin, the person who was detained is still there, you go and deal with it, and you have to make enough evidence. Then he looked at the crowd and said, "I'll go out, if there's anything, I'll talk about it when I come back, let's end the meeting." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

After that, Sun Guoxin got up and walked out of the conference room directly. Fan Keqin understands that Sun Guoxin is going to find a way, in fact, at this moment, everyone understands that someone must have deliberately come to such a show today, as for whether Ouyang is this person, it is not easy to say, but it is unlikely. Although he is also an important chief of defense, it is still a bit too difficult for him to pull the security bureau into the water. &a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin didn't care about this, he also got up and said hello to everyone, and went directly to the field team and found Wang Zhanyuan. The latter's face is not very good-looking now, and when he saw Fan Keqin, he asked directly, "Headquarters, is there something wrong?" ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin smiled, "Don't think about it, let's do our job well." Then he asked, "What about the suspected fake commissioner?" ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Wang Zhanyuan replied, "I am under house arrest, and there are a few brothers watching in the next room." Speaking of this, he lowered his voice and said, "There is indeed a problem with the procedures, but this kid's own documents are real, so he didn't dare to close them in the cell." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin nodded and said, "Well, okay." Did you ask something? ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Wang Zhanyuan shook his head and said, "Don't open your mouth at all, we don't dare to punish yet." If you don't say anything, you're like a dumb person, a deaf person. ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin said, "It's okay, what about his appointment?" ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Wang Zhanyuan said, "Here, do you need it?" ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin said, "It's good to be here, in this case, I will call the legal department of the intelligence department and ask them to help scan the fingerprints on it." As long as you have this evidence, that's fine. ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

When Wang Zhanyuan heard this, he frowned a little, and said, "Headquarters, the appointment is a paper document, this thing is not easy to extract fingerprints." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin understands that the fingerprint extraction technology of this year is definitely not as good as that of later generations, but the principle is the same, for example, on the iron handle, if the fingerprint is extracted, a very soft small brush will be used to glue the very crushed extraction powder, and then gently stick it to the handle, so that the fingerprint will be revealed. But on paper, it's a bit more difficult. &a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin said, "It's okay, I know what to do, did you see him take the document empty-handed?" ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Wang Zhanyuan nodded and said, "Yes, I'm sure of that." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin said, "On the way to check his fingerprints, there was no glue, right?" Naturally, there was a reason for him to ask, because when he was lecturing to his subordinates, he also taught some small skills from time to time. For example, what to do when wearing gloves would attract attention, but without leaving fingerprints. What to do, it's very simple, just use glue, apply the lines on your hands evenly some time in advance, and then apply another layer after drying. In this way, in a short period of time, your fingers touch anything, and your fingerprints will not be left. &a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Wang Zhanyuan immediately said, "I checked it, and I also thought of fingerprint evidence at that time, so when I handcuffed him, I checked it again, and there was no problem." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin smiled: "Then it's no problem." As he spoke, he picked up the phone directly on Wang Zhanyuan's desk and dialed the intelligence department. After letting the operator transfer, it didn't take long for Zhang Terrier's voice to sound, "Hey? Who is it? ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

"Terrier." Fan Keqin said, "It's me, busy or not?" ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Zhang Terrier said, "Yo, Keqin, what's the matter, ask me to drink two cups at night?" ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin said, "I want to be beautiful, I haven't finished my work yet, let's talk about it when it's over." Hey, terrier, I'm looking for you to do me a favor, you asked your appraiser to come over with a set of fingerprint extraction tools to help me extract my fingerprints on paper. ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

"On paper?" Zhang Terrier said, "Okay, but you have to look at what kind of paper, if it's too rough, I'm afraid it can be extracted, and the fingerprints may not be." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Fan Keqin said, "It's okay, you just let them come." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

After hanging up the phone, Fan Keqin asked Wang Zhanyuan to get some phosphor, of course, this thing can't be found in ordinary places, but let him go directly to the local university with a laboratory, as long as he knows a little about chemistry, he can get it out quickly. &a;lt; r /&a;gt;

&a;lt; r /&a;gt;

About half an hour later, two inspectors from the Intelligence Service arrived, carrying a wooden box containing a set of fingerprint extraction tools. In fact, there are always people who doubt the fingerprint extraction technology of this era. &a;lt; r /&a;gt;

&a;lt; r /&a;gt;

But there really is no doubt that in this year, there is indeed this technology, and it seems to be high, but it is really not that complicated. If you know a little bit about the principles and don't even use professional tools, you can basically do the job in your own home. You don't have a professional magnetic powder, don't be afraid, you can sometimes get the kind of starch you eat. Therefore, there is really no need to doubt it. &a;lt; r /&a;gt;

&a;lt; r /&a;gt;

After Wang Zhanyuan came back, Fan Keqin began to make it hand in hand, which was simpler, the phosphor itself was grinded. But now the requirements are more rigorous, with Fan Keqin to bring out a small part of the professional powder brought by the appraiser, put it in a glass dish, and then gently blow the phosphor, blow out the tiniest layer of it, mix it into the professional powder, and then make it even, and irradiate it with strong light for a while. &a;lt; r /&a;gt;

&a;lt; r /&a;gt;

Then Fan Keqin returned the glass to the two appraisers, and said, "You have learned something from me again, go back and tell you the section chief, you owe me a meal." ”&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

The two appraisers smiled and nodded, and began to work. Sure enough, the phosphor was mixed into the professional powder and was exposed to strong light, so that when the paper was stained with powder, the fingerprints on it would be clearly visible as soon as the light was turned off...... &a;lt; r /&a;gt;

&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

&a;lt; r /&a;gt;

&a;lt; r /&a;gt;
