Shi Xingyan's case is really too involved. The chairman of a multinational group went crazy for no reason. Once the news spreads, a Category 8 hurricane will blow up in Jishui City and even the whole world...

At that time, countless people will flock to the police. Faced with public opinion, the pressure on the police can be imagined.

What's more, there is a more difficult problem. Eleven fully armed foreign mercenaries were trapped in Jishui.

If it spreads internationally, maybe...

This matter is really involved, and now Yan Zheng is the only insider.

Director Li and the others have to pay attention.

At first, the four drivers concealed something. After repeated interrogations, they also confessed some of what happened. They only knew that in the afternoon, Shi Xingyan took them to the Instant Mirror Villa to pick up eleven mercenaries and an old man in his sixties.

Then we drove to the Laoseng Temple behind Gejia Village. Now the old man mentioned by the driver was nowhere to be seen. According to the driver's description, the police investigated the surrounding surveillance and found that the old man seemed to have disappeared out of thin air without a trace.

The surrounding terrain is extremely complex, the mountains are rolling, and the monitoring facilities in the surrounding villages are imperfect. If the old man hides in the mountains, he will not be found for a while.

We can only expand the scope of surveillance, monitor the entire Jishui City at any time, and focus on investigating all mountainous areas.

The police believe that no matter where the old man is hiding, he will be found one day. People have to eat, drink and have sex. As long as his head is exposed, the police will be able to follow the clues and catch him. Now Jishui City has set up a dragnet, waiting for the old man to fall into the trap.

In order to arrest the old man, the police deployed all the police forces they could. Before catching the old man, Yan Zheng's confession became particularly important.

Director Li and the others urgently need the details of the case to deal with the oncoming group of reporters.

After all, paper can't cover the fire. There was such a big commotion in Gejia Village, and gunshots were heard everywhere, which could be heard in several villages in the surrounding area.

Although the police have blocked the news immediately and sealed off the surrounding area, it is inevitable that the news will leak out. Besides, Shi Xingyan, the richest man in Jishui City, is crazy. The police cannot hide this news for long even if they want to. It will be spread all over the city in less than a day.

Know.

Already, reporters with a keen sense of smell have come to the door after sniffing out the news.

But the police were blind and knew nothing. The client was seriously injured, dead, and crazy.

The only normal person is Yan Zheng, otherwise Li Tao, the director of the Jishui Municipal Bureau, would not personally be in charge of the Criminal Investigation Division, waiting for first-hand interrogation information.

This shows how seriously the city attaches importance to this case. Today, the police tried to pry Yan Zheng's mouth open no matter what.

Yan Zheng didn't know the turmoil in the city behind this, and he didn't even think that the matter would get so big. He simply thought that the mercenaries and Shi Xingyan were crazy. What he didn't expect was that the mercenaries were destroying his psychology.

A bad incident occurred.

Sitting on a white leather chair, the stainless steel electrode sensor has three tentacles worn on Yan Zheng's fingers. The silver-white luster of the metal is very sci-fi and is used to measure changes in skin resistance. The respiration sensor is similar to a strip with elasticity.

It is attached to the seat belt and fastened to Yan Zheng's chest to measure changes in breathing; the pulse and blood pressure sensors are also red ribbon-shaped and worn on Yan Zheng's arms to measure changes in people's pulse and blood pressure.

There was even an electrocardiogram instrument, with various sensors attached to Yan Zheng's chest.

The staff at Yan Zheng's side were busy putting various testing instruments on Yan Zheng, and in the monitoring room separated by a wall, everyone was also busy.

Shen Pei enthusiastically introduced to Director Li how the lie detector works on suspects. Director Li was extremely interested in this point and listened carefully to Shen Pei's introduction.

“The use of a polygraph itself can cause a certain amount of psychological pressure on criminal suspects, and combined with policy education and the use of evidence, it can encourage criminal suspects to shake down, confess problems or explain the truth.

When using it, the polygraph examiner repeatedly explains and emphasizes the scientificity, objectivity, fairness and effectiveness of the polygraph, and uses the suspect's sense of mystery about the polygraph to make him feel that the polygraph is sensitive.

People who do not tolerate deception are worried that if they lie, they may be seen through on the spot, exposed and exposed, thus aggravating their psychological pressure.

Before the formal measurement, the polygraph examiner also needs to have a long conversation with the person being tested. The purpose is mainly twofold: first, to understand the personality and honesty of the person being tested through conversation and interrogation, so as to finally determine the interrogation during the formal measurement.

questions and interrogation methods; the second is to introduce the "consistent correctness" of the polygraph to the person being tested, so that they can be convinced that the polygraph has the reliable function of accurately distinguishing between truth and lies, thereby creating a deterrent effect on them and eliminating them.

A fluke mentality. In order to make the subject convinced that the lie detector cannot be deceived, the polygraph detector also requires the subject to participate in a demonstration verification. Oh, it seems to be about to start. You can see this in a moment! "

Seeing news of confirmed tests coming from various interrogation rooms, Shen Pei took the initiative to interrupt his explanation and looked worriedly at Yan Zheng, who was lying on the chair with a solemn expression.

Even Yan Zheng, an old fox, will probably feel more pressure when facing the lie detector. I hope he can survive smoothly...

Yan Zheng was indeed a little nervous while lying on the chair, and his heart rate remained high.

The polygraph detector began to talk to Yan Zheng about everyday matters in an attempt to divert Yan Zheng's attention. Most of the questions were related to Yan Zheng's family and work.

But these were issues that Yan Zheng didn't want to talk about and couldn't talk about.

His parents died young and he is still unmarried. Talking about family is just rubbing salt into the wound. Talking about work, Yan Zheng dare not speak for fear of scaring them to death.

Faced with Yan Zheng's lack of cooperation, Captain Liu couldn't help but yelled anxiously: "Yan Zheng, please cooperate. This is not another place. If you feel that you have been wronged, then cooperate well and prove your innocence."

!”

Yan Zheng yelled irritably: "I'm talking about your sister. My parents died young and I am still single. You have already investigated me and I should be very clear. Talk to me about family? Why do you want to hear about the struggles of orphans? As for my work,

Don’t you know what’s going on in your mind? Just ask Shen Pei. I have invested in a company in the past few months and haven’t made a penny. I even lost money in it. Why do you ask me these questions? What’s the wound?

Sprinkle salt on it!"

Liu Bo was speechless by Yan Zheng, and turned to look at the testing personnel next to him. The testing equipment staff nodded at Liu Bo.

Captain Liu instantly knew in his mind that what Yan Zheng said was true. However, his experience was really too tragic, and it would be a bit inhumane to talk about such an issue again.

Yan Zheng, who was opposite, was also squinting at Liu Bo's interaction with the polygraph supervisor. He believed that he could pass this test. What he told was the truth. The company did not make any money and kept paying the Lantern Ghost.

They pay wages.
