It may be very difficult to find Guo Mingliang, but it seems that it is not difficult to catch him.

At least after Ding Fan found him, after just a brief conversation with him, Guo Mingliang stretched out his hands very cooperatively and put the handcuffs on his hands.

The arrest went completely unexpectedly smoothly, and Ding Fan walked into the factory in less than an hour before he came out of it.

The people arranged by the Zhao Bureau have not yet arrived, and the arrest task on Ding Fan's side has ended.

Huang Yao and Miao Hui waited outside for a long time, and they didn't expect that Ding Fan would directly bring people back at this time.

But in Ding Fan's opinion, what's so difficult about this?

It's just a catch, and he's still a technocratic murderer, and to put it mildly, he's just a powerless literati.

To say that he is a little cautious, or a little bit of a small means, but when he wants to confront the police head-on, he knows that he has no ability at all, and after the fight, he knows very well that he will be cleaned up very badly.

So he arrived directly, stretched his hands, and obediently followed Ding Fan away.

After all the people brought by Zhao Ju arrived, they were all stunned in an instant when they looked at the people who had been arrested by Ding Fan.

I have to say that in their impression before, this cruel murderer is definitely not what he is now, at least his current look looks completely wrong, there is no imaginary madness and anger, nor the slightest arrogance, he does not look like the kind of person who kills people like hemp at all.

Even some people in the crowd were curious, did Ding Fan catch the wrong person this time?

But today, after all, the person was caught, and the task was completed without danger.

But after returning to the police station, in the interrogation process, a more headache finally appeared.

After all, this Guo Mingliang is a professional talent of the country, and one person can completely drive this troublesome equipment, obviously in terms of mental quality, it is by no means ordinary.

This kind of interrogation method obviously has no effect at all for him.

In the face of this situation, Zhao Ju was also a little helpless, and even a veteran criminal investigator like Kong Jie failed to succeed in the face of people like Guo Mingming.

On the contrary, Ding Fan sat outside and watched for a long time, and he didn't know what he was thinking at this time, and he didn't even seem to be watching what was happening inside.

In fact, after Ding Fan met Guo Mingming, Guo Mingliang had already proposed that he could trade with him, and Guo Mingliang could tell him anything he wanted to know.

But there is one thing, Ding Fan must help him protect the equipment in the basement and the woman who is soaking in the nutrient pool.

It is said that Ding Fan should accept this proposal, at least he thinks so.

But Ding Fan only thought about it for a while, directly rejected his opinion, took out the handcuffs and buckled them on his wrists.

Under his extremely surprised eyes, he was taken into the police car.

And at this moment, in fact, Ding Fan was still thinking about the woman he found in the basement before.

If Ding Fan is not mistaken, this woman should be the key to the whole case.

Guo Mingliang is a very smart person, and he used to study medicine, not only in medical treatment, but also in the mental aspect, I'm afraid he is not bad, if nothing can break his inner defense, don't even want to pry his mouth open.

At this time, it is the time when the two of them are fighting each other, and no one can retreat at this time, as long as Guo Mingliang keeps his mouth shut at this time and doesn't speak, he will have the opportunity to mention the possibility of trading with Ding Fan at one time.

In this way, he still has a chance to protect the last woman, and Ding Fan can only bow his head under pressure and slowly talk to him about cooperation.

And Ding Fan also knew that the struggle between the two had actually just begun, and from the beginning, he was already at a disadvantage.

I don't have many hole cards to use, and the only weakness I can catch is actually the 'corpse' found in the laboratory.

"Ding, do you have any opinions?" Director Zhao was the first one who couldn't hold the pressure, not that he couldn't bear the matter, but in recent times, he has followed Ding Fan to carry I don't know how much pressure, last night's incident, he hasn't explained it clearly to the above, and it has only been less than half a day, and the final culprit of the corpse case has also been arrested.

I have always been very concerned about this case, but there are a lot of things involved in this case, and it is Ding Fan who helped to investigate, and it is inconvenient for the leaders to ask too much, so they can only come over from time to time to knock Zhao Ju and ask about the current situation of the case.

But now, although the person has been caught, he has also encountered a very troublesome problem, that is, Guo Mingliang has been biting hard, but he just doesn't open his mouth.

It is said that now this case has been investigated to this point, and many of the evidence chains have been completely closed, even if he doesn't open his mouth, the final case can actually convict him.

It's just that Zhao Ju still hopes that in the end, this case can be handled more perfectly, no matter what, it is best that he can confess his guilt in person.

And this point is actually almost the same as Ding Fan's thoughts.

Because what he wants is not only for the prisoner to admit guilt, but also for Guo Mingliang to make the relationship between him and the black market clearer, which may be of other help to the investigation of the black network in the future.

"He's a smart man, ordinary means, for him, can't have much effect!" Ding Fan hasn't said a word since he came back, he has been silent, until this moment, he said the first sentence: "Use some high-tech means, bring him a lie detector, he is originally a highly educated person, for scientific and technological things, he should be very aware of the effect, don't give him a little bit of power, kill his sharpness, he really has no one in his eyes." ”

As soon as Ding Fan said, Huang Yao, who was following behind Zhao Ju, suddenly became excited, after all, things like lie detectors have only been seen in movies before, where can I see this thing in real life!

When I heard that I would see this thing during this interrogation, my eyes lit up with excitement.

But this is a bitter Zhao Bureau, he has indeed seen the lie detector thing, but he only saw it once thirty years ago, and when he saw this thing later, it was basically used as a collection in the museum.

There is a new generation of polygraph now, but that thing is not a standing equipment in the police force, and if you want to use it, you have to cooperate with the relevant departments to get it, and I am afraid that it cannot be used in vain.

"This ...... I'm a little embarrassed to say it, we don't have this kind of funding this year!" Zhao Ju's face was a little embarrassed, this old face couldn't help but be a little red at this time, and he reached out and scratched it twice on his head and said: " Originally, this year's budget was not very abundant, and recently there was a break in time, and everyone has been working overtime for one after another, and the budget on our side is indeed a little tight, with a little more money left, and it will support two months, even if we want to rent this polygraph, I'm afraid we won't be able to get this money!"

After making trouble for a long time, it's not that there is no place to rent the polygraph, but that the funds are tight.

In fact, it's right to think about it, the previous case itself was temporarily pressed in their bureau, and the cost of such a case is indeed not small, and the lack of money at this time is actually in the past.

"It's okay, there is no polygraph, it's not impossible to ask someone to make a similar one temporarily!" Ding Fan didn't think about using a polygraph at the beginning, but he just said it casually, and now he was a little embarrassed to see Zhao Ju, so he glanced at the dilapidated tape recorder on the corner of the wall, pointed to the tape recorder and said: "I look at that thing, it's almost the same, anyway, the latest polygraph, he hasn't seen it before, let's show him a polygraph to distinguish the authenticity." ”

What kind of means is this?

When Zhao Ju heard this, his whole mind was messy, and he couldn't understand what Ding Fan wanted to do, he said that he used a lie detector before, but now he has to use a broken radio to fool around, isn't this a bit too hasty?

But Ding Fan has already said so, and he has no other way now, so he can only try it, but this broken radio, if you want to take it out to deceive people, it seems a little unlikely, at least there must be some decoration, it looks a little similar!

Ding Fan had already thought about this, Victor should still be there at this time, and asked him to come over and do a favor, simply clean up the radio, change it, and make it look more like a lie detector, so that it doesn't use too much function, as long as it can deceive people.

This kind of trivial matter, let alone a master like Victor, if you change it to a street performer, I'm afraid you can get a rough idea.

In less than half an hour, a new polygraph was in his hands.

Of course, this so-called lie detector is actually an empty shell, which looks a little bit like that, but the function is like that, after connecting the power supply, there will be a rustling sound behind the press of the switch, as if there is a special pen sliding.

In fact, it's just that Victor installed a pencil in the back, and added a piece of paper underneath, and the rustle was naturally completed, it seemed that this thing was drawing a heart rate graph, but in fact this thing was just in the same position, constantly rubbing back and forth, and nothing was drawn on it.

The rest of the things have to find Xiao Huang in the forensic office, this scene really needs to find someone with a little professional ability to come over to play, otherwise it is very likely that Guo Mingliang will see through it at a glance, after all, he used to study medicine, and it is really not easy to deceive him in this regard.

After these things were ready, Ding Fan took the opportunity to say to Zhao Ju and asked him to take a look at this thing as well.

"Not to mention, after this broken radio was modified, I really can't tell that it was a radio before. Zhao Ju cautiously turned around the side of the device that he didn't know what it was, a little curious and wanted to reach out, but he was afraid of breaking the thing, so he had to stand aside and ask: "Can this work? Even a lie detector can only determine whether what he said is true or false, and it can't pry his mouth open after UMC?"

Don't really say it, what Zhao Ju said is not wrong at all.

In fact, this improvised 'lie detector' is just to add a weight to this scale, and people with heavy hearts are indispensable to be nervous when they encounter this thing.

And when people are nervous, the best way to relieve them is to speak, use small talk, and break down their stress to the side.

So this 'lie detector' itself is not to detect the truth of his words, but to pry open Guo Mingming's mouth.
