"I, I...... I embezzled the company's money, about 2 million, I really am, I, I don't want to, you should understand, an elite like us, 2 million is really nothing, as a financial director, I just took such a little, it's already a lot of duty......"

The results of the polygraph came out, and that critical question, all qualified.

But there is one person who collapsed after a polygraph, and he is Guo Xiaochuan.

Accident, absolute accident.

In the West Mining Bureau, the atmosphere is very solemn.

This case, many new comrades followed suit, and according to Gao Lai's theory, it was like taking a group of intern doctors on ward rounds.

In fact, it is true, but now, no matter how novice can see it, the detection has come to a very embarrassing situation.

The last resort was used, but unfortunately, we still failed to catch the murderer.

Everyone's eyes were looking at Gao Lai, and the meaning of this gaze was also very clear.

What to do?

Gao Lai himself wanted to know what to do, he really didn't expect this to be the situation.

"Master, Team Zhou is here. Bai Mulan said softly.

"......," Gao Lai nodded.

Team Zhou was resolute, and directly came over to split his head and cover his face, "The progress is to arrest an economic criminal? Gao Lai, Gao Lai, all the support is given to you......, right? Otherwise, the impact will be too great, and other enterprises will have to operate!"

"Of course, of course, let them go. Gao Lai kept nodding, but, "There are a few more important suspects......

"Why are you still talking about conditions?" Team Zhou was furious, "Now that two people have died, there is no progress in the case at all, and you still want to keep people, do you still want to do it as a detachment leader?"

"No, leader, we have the right to limit them to 48 hours, but this time I also know that the pressure from the superiors is too great, after all, the Lin family is a key enterprise in our city, but I really think that the murderer is among them, let us leave a few." ”

Team Zhou thought about it, Gao Lai's attitude was also very sincere, and finally gritted his teeth, "I hope you are not messing around this time! ”

"Please rest assured!"

And so ...

"Don't let us go!"

"Well, you're too messy. ”

"I really can't stand it, so I just handle the case? I only play fatigue tactics?"

Tang Ziqiang, Zhai Hao, and Cui Xiaonan were left behind, and of course, the financial director was also transferred to other units.

These three people are Gao Lai's last line of defense, they were originally key suspects, and Gao Lai left them, which is a helpless solution.

This polygraph result is really curious, especially Liu Xiaogang...

"Master, how is this possible? I can't find out if I take a lie detector?"

"You kid, what about your job?"

"I'm watching and watching, I don't dare to let go of one, it's all slow, I'm careful. ”

Bai Mulan's brows kept frowning, and Liu Xiaogang's curiosity was too heavy.

According to a series of previous preparations, it can be said that this polygraph should be foolproof, under the toss of fatigue tactics, how can there be a fish that slips through the net.

"Could it be that person is so strong-willed?" Liu Xiaogang remembered this sentence.

Bai Mulan sighed, "I'm serious about being your master now." ”

"Great!" Liu Xiaogang knew that the answer he wanted was coming.

Bai Mulan thought for a moment and said, "Actually, Guo Xiaochuan's confession shows one thing. ”

Liu Xiaogang answered, "Our lie detector is easy to use." ”

"......" Bai Mulan gave a sharp look.

"Hey...... Master, I'm just going to liven up the atmosphere. Liu Xiaogang laughed to himself.

"Your joke, it's really not funny. Bai Mulan didn't have too much harsh criticism, and the pressure on the apprentice was not small, and he probably hoped to relieve everyone's pressure, which was goodwill, so he continued: "You know the principle of the lie detector, right?"

"Know that by monitoring the performance of breathing, heartbeat, brain waves, skin secretions, etc...... The success rate is more than 8 percent. ”

"Yes, there is a chance of a mistake, about 15 percent. Bai Mulan nodded, "Although Guo Xiaochuan's confession was an accident, it also shows that the pressure of polygraph on these suspects, their psychological pressure is definitely not small, and our fatigue tactics definitely have an effect." So, let me ask you, what does this mean?"

"This ......" Liu Xiaogang opened his mouth and didn't know what to say.

"Combined with the clues we got before, on the whole, assuming that the murderer is among those six people, I think there are only two points that the murderer can escape the lie detector. ”

Liu Xiaogang listened very seriously, and this time there was no idea of joking.

"The first point is that the murderer probably learned the news a long time ago, that is, Lin Kai had an illegitimate child, and he knew about it for a long time. ”

"Oh~~" Liu Xiaogang suddenly realized: "According to the current situation of this case, the murderer should be a person with a high IQ, high education, strong body, and social elite, and ......"

"And it's likely that he knows a lot about our police's methods and procedures. ”

"In addition, we arrested Qin Lan before, which is equivalent to telling him what we want to measure, but our action has hardly been delayed for a minute or a second, and now it is less than three days before Lin Kai's death, even if we start preparing from that time, it seems to be too late. ”

"Yes, you've grown. Bai Mulan nodded.

"Hehe......" was praised, and Liu Xiaogang scratched his head.

Bai Mulan continued: "Actually, this is a reversal, the murderer should have known that Lin Kai had an illegitimate child a long time ago, and this matter is very common for him, so those breaths and heartbeats are ...... It was possible for him to take control in a short period of time, or he had just been preparing for a long time and guessed that we would have this hand. ”

Liu Xiaogang nodded, indicating that he had learned, but he was shocked by the strength of this murderer.

"I told you about strong willpower before. But I heard Bai Mulan continue: "Why is people's willpower strong? Simply put, it means that I feel that I am doing a right thing, something meaningful." ”

"Master, my back is a little cold. Liu Xiaogang said inexplicably.

"Anyone will feel guilty after committing a crime, they will be afraid, especially when they see us, no matter how powerful they are on the surface, but they are extremely weak inside. Bai Mulan sighed, "Murderer, it is correct and meaningful to determine that your murderous behavior is correct. Guilt, I can't say no, but it's relatively low, and he's extremely determined. ”

"......" Liu Xiaogang was stunned.

The suspects in this case are all social elites, and their worldviews are not so extreme, but now, the murderer feels that his murder is correct.

The point is that Lin Kai may not be a good person, but he is not a bad person, and his company has solved the employment of so many people, and the quality of the products has always been very good. Qiu Fang, wave a little, but the sin is not to death, right?

It's scary to think about.

What kind of murderer are we up against?

High IQ, high education, strong body, social elite, and familiar with our method of handling cases, the most special thing, he also has a strong sense of justice, at least he believes that his murder is correct.

Wait a minute.

What if the killer is not among the suspects?

Yes, the above reasoning is based on the premise that the murderer has passed the polygraph, what if the murderer is not there?

Are we going in the wrong direction?

Liu Xiaogang's bar essence value began to skyrocket again.

"Hurry up, maybe you'll find the murderer!"

"Yes!"

Bai Mulan patted her apprentice's head, and just said a little too much.

But at this time, Gao came to her.

"Mulan, call him, I want to hear his analysis. Gao Lai's dark and thin face was quite haggard.

Obviously, the fatigue tactics are a bit like the Seven Wounds Fist, and now Gao Lai is hurting.

Bai Mulan knew in her heart that the master was also wavering, and he must be wondering if we had made a mistake.

Without saying anything, he took out his phone.

......

......

"Mulan, the direction is right, the murderer is among the three suspects!"

Wu Gan received the call, and his answer seemed to have not been thought of.

"Really?"

"Mulan ......"

"Told you, don't call me that. ”

"Okay, I'll tell you, the results should be available tonight......"

"What a brag!"

"That's okay, I won't blow it, I will definitely solve the case within 48 hours, that is, I will crack the murderer's alibi, as well as his modus operandi, and I will find evidence......"

Over there, the phone has hung up.

Wu Qian smiled and took down the phone, he was not affected, and he was in a pretty good mood.

Some people say that green makes you feel better, and now it seems that it should be true.

There is a large area of green in front of you, of course, the mood will be good, and on top of this green, there is also black and white decoration, which is even more interesting.

"Ah......h

Lin Bing, who was wearing a work clothes, was playing with a cow at this time.

Well, in fact, she was playing alone, and the cows were more attentive to grazing and didn't pay much attention to her.

After all, it was the eldest lady of the Lin family, and when she came, it created quite a battle.

"This feeling is good, the eldest lady can come over to play at any time, we are all welcome, but I am afraid that our canteen still has a place to rest, the eldest lady is not used to it, in addition, this is a ranch, there are more mosquitoes. ”

The manager of the ranch, surnamed Zhang, has a good face and likes to laugh.

However, Wu Qian is really here to get down to business.

"Manager Zhang, can you tell me about Vice President Tang's situation?"

"Mr. Tang, then you are asking the right person, let me tell you, Mr. Tang is a good person, really good, leveraged, some of our ordinary workers here are very familiar with him, Mr. Tang is really a person who works hard......"

"Oh......"

Wu Gan came to the ranch this time, the purpose was very simple, he didn't investigate Qiu Fang's alibi before, but now, he is investigating Tang Ziqiang.

"Can I take a look at the surveillance on the night of the 14th?"

"No problem, please here. ”

Manager Zhang led the way, and as soon as Wu Qian moved, Lin Bing came up.

"Do you really think that Brother Tang is the murderer?"

"Can't he be a murderer?"
