It does save a lot of trouble to have an action department, the suspect is a lie detector in the farm, and seven masters, including Fang Liming, are staring, so there is no need to worry about the investigation department at all.

Two hours ago, the suspect signed a detention summons, and he had a criminal detention warrant and a criminal detention notice for the suspect's family.

There are not so many coincidences in the world, Tai Chao, like Director Han Da who is far away in Jiangcheng, thinks that Xu Fanhai is basically the murderer. Because in addition to fingerprints, in addition to this series of coincidences, the fake letter of introduction back then was also a clue.

After tracking down Ke to Bin'an County, he not only confirmed the identity of the victim, not only investigated the social background of the victim and the suspect, but also conducted a handwriting test. Based on the handwriting of some suspects secretly collected by the investigators of the county bureau, it was confirmed that the "Zhang Yiqing" on the fake letter of introduction was written by Xu Fanhai.

But if you want to turn the case into an ironclad case, these alone are far from enough. There must be a motive, and it is difficult to bring it to justice without a motive.

Tai Chao was not only worried about the case, but also worried about himself, lying on the conference table of the police command car, looking at the photos on the Internet, videos and comments regretting it.

Liu Huafeng was angry and funny, patted him on the shoulder and said sympathetically: "Brother Chao, don't be sad, you are in the limelight, of course you have to carry the black cauldron, which is very fair." ”

He played too much, and after detaining the suspect, he actually learned from Director Han and wanted to show his gentlemanly demeanor. Feeling that the detention action had ruined people's weddings, he came to borrow flowers to offer Buddha, and sent the flowers that the hotel had originally prepared to give to the newlyweds to the banquet hall, and apologized to the bride and groom on behalf of the provincial public security department. I wish the bride and groom to grow old together and tie the knot forever.

Very user-friendly. It is very much in line with the style of Director Han Da.

The key is that he forgot that there were hundreds of guests at the wedding banquet, and each of the guests had mobile phones. On such a festive day, everyone wants to take a photo and record a video as a souvenir, and young guests should not only take a souvenir, but also share it with their friends, and post it on the Internet to let more people know.

In this way, he became famous, and in just two hours, he became the focus of attention of many netizens.

It's not a mixed reputation, it's a piece of praise.

If the case is solved. If it is confirmed that the suspect is the murderer and the suspect can be sent to court, then he can become the image spokesperson of the Jiang Provincial Public Security Department. But if the case is not solved and the suspect cannot be sent to court, not only will he become a laughing stock, but even the provincial department will be laughed at by the people of the whole country.

The reason why the leaders of the department sent Deputy Director Yang Zhongwang to "801" can be said to have a lot to do with him.

Tai Chao threw his phone aside, cheered himself up, and said, "I feel that the polygraph should be fine." ”

"What if there's a problem?"

"I have a warrant of arrest, and I do what I do. What am I afraid of? It's a big deal to apologize to him and accompany him to the hotel to announce that the case has nothing to do with him. It is only a custodial summons, not a detention, let alone an arrest. Anyone who knows a little bit of the Fa knows that this is normal. ”

Dare to learn from my master, and I don't weigh whether I have the capital.

Jiang Yi almost burst out laughing, knocked on the table and said, "Brother Chao." Don't answer what you asked, what Team Liu asked was how to explain to the hall. Not with the suspect. ”

Let you go to the custody of the suspect, you run to the limelight. If you are in the limelight, you will be in the limelight, and you will actually represent the provincial department, if you really go online, you will be unorganized and undisciplined.

The impact was created, how could Tai Chao not know the severity of this matter, and sighed and said: "Section Chief Jiang, I really have a good heart, I really haven't thought of anything else." Forget it, it's useless to say anything now, it's really impossible to go back to the original unit. ”

He was worried, and Xu Fanhai, who was undergoing a polygraph test, could no longer be described as worried. On the surface, he is calm and composed, but he is extremely nervous in his heart.

It was the Public Security Bureau, not the Public Security Bureau. When so many people brought him downstairs, so many policemen, so many police cars, if there was no evidence, they would not have done it.

The most terrible thing is polygraph, no matter what you say, the instrument can show it, and I heard that the polygraph conclusion cannot be used as evidence, and I don't know if it is true or false.

"Have you ever been to BJ?"

"Nope."

After being taken into the car, he didn't see an acquaintance, and the case-handling staff showed that he was from the provincial department, Xu Fanhai didn't have the confidence he had before, and he was very cooperative, and at the same time secretly warned himself not to panic.

The polygraph expert then asked, "You haven't lied about some serious questions?" ”

"Nope."

These are well-designed "yardstick" questions, which are the "baselines" that Director Han Da said to Yang Zhongwang and Xia Moqing. When answering these questions, the tester will generally answer "no" with a very resounding answer. When answering, the physical indicators can be used as the general indicator values of the person being tested.

Then ask questions related to the case, if the testee's heartbeat, breathing, blood pressure and other values change drastically when answering, and the index is higher than the index of the "standard" question, it may be lying.

Because when people are telling the truth, the brain only needs to listen and speak, and there will not be a lot of time for active thinking, and the fluctuation of the number jù monitored by the instrument will not be obvious. But if you lie, all the brain has to do is listen, think, and speak, and although it is short, it can be accurately captured by a lie detector.

After asking a few painless questions, he answered them fluently without thinking.

The polygraph expert asked coldly, "Why did you kill Shi Xiaoguo?" ”

"Nope!"

In the hotel, he only said that he was suspected of a murder case of the deceased, but it was not as direct as it is now, and he didn't even mention it along the way, and he was lucky a few seconds ago, secretly wondering if it would be some other case, and in the end it was still Shi Xiaoguo.

Xu Fanhai seemed to realize that he was answering too quickly, and pretended to be frank and swaying: "Shi Xiaoguo is a famous ruffian in Shidian, I remember him. Comrade policeman, he died? When did you die? ”

"I asked you, not me, you just need to answer whether there is any."

"Okay, okay, finish it early, finish it early, my wife is not in good health, the hotel must be in a mess now, I must do my best to go back as soon as possible."

The face is not red and the heart is not beating, but it makes people feel that he has been wronged, but on the monitor of the polygraph. His physiological responses fluctuated dramatically.

After studying the case file yesterday, two young polygraph experts designed a total of 10 questions in 4 sets. For the next hour, I repeatedly asked questions unrelated to the case, such as "what is your name" and "what do you do". At the same time, it is interspersed with questions such as "why did you kill Shi Xiaoguo", "Who killed Shi Xiaoguo" and other related questions.

The atlas showed that with each answer to the relevant question, his heart rate would increase, his blood pressure would rise, and his physiological characteristics would fluctuate more and more violently, completely exposing his heart weakness.

After asking the last question, the tall polygraph expert nodded slightly at Fang Liming, who was standing behind him, and immediately took off the sensor and began to pack up the equipment.

After a while, Tai Chao, Liu Huafeng, and Li Zhongchen walked into the farm greenhouse. Take out the detention warrant and ask him to sign it as you would in the hotel president's office in the morning......

I can't hear it, but I can see it.

Director Han finally breathed a sigh of relief, picked up the cup and took a sip of coffee.

The stinky boy in the LCD screen caused such a big turmoil, Yang Zhongwang was not as calm as him, and asked with a puzzled face: "Director Han, when are you going to interrogate?" ”

Han Jun put down the cup and said lightly: "Starting from Bin'an now, it is estimated that we can only be escorted to Jiangcheng after twelve o'clock." How to judge in the middle of the night, let's talk about it tomorrow. ”

"Then who are you going to let the trial do, do you want me to recommend you two experienced pretrial experts?"

"It's okay to recommend two, but you can only be an assistant."

"You're the right person?"

"Not suitable. There is no one more suitable than him. It should be almost there, and people have come from far and wide to go downstairs to greet them. No rudeness. ”

Wu Zhuoxi was happy, and couldn't help but smile and asked, "Director Han." Who is that pre-trial expert, even you have to go downstairs to greet him. ”

Han Jun asked rhetorically, "Wu Bureau." Do you think I didn't go down to greet me at noon, and I feel neglected? ”

"How dare you, let Director Han greet you, I, Wu Zhuoxi, don't have this qualification, it is estimated that few people in the whole Jiang Province have this honor."

Yang Zhongwang got up and urged: "Director Han, who the hell is it, don't sell Guanzi." ”

"It's not that I sell Guanzi, it's that you don't know each other, and maybe you haven't heard of it."

"Let's hear it, maybe we really know each other."

"Qin Xianghong, to be precise, he is not a pre-trial expert, but he is very familiar with the case, and there is no generation gap with the suspect, so he can talk together. Prescribing the right medicine is more effective than any expert. ”

Yang Zhongwang asked in surprise: "Old comrade? ”

"Otherwise, I can go down and meet you."

Han Jun explained with a smile while leading them downstairs: "Qin Lao was the deputy leader of the task force in charge of this case back then, and the clues of his fingerprints were provided by his old man. ”

Yang Zhongwang was completely convinced, and asked with a wry smile: "How old is Old Qin this year?" ”

"It's almost 70, a few years older than the suspect, so they don't have a generation gap."

The suspect has seen the world and experienced a lot of ups and downs, and he really doesn't care about the ordinary young people, Wu Zhuoxi reacted and said to himself: "Let him not be qualified to rely on the old and sell the old, maybe it can really work." ”

"I'm afraid that Qin Lao won't be able to bear it, after all, he is so old."

"Yang Ju, you're afraid that Qin Lao won't be able to bear it, and I'm still afraid that Xu Fanhai won't be able to bear it. He is in his 60s and is not in good health, so we must be humane, respect his personal rights, and not engage in fatigue tactics. Let Qin Lao and his parents recall the era of burning passion together, and when they have a common language, they will definitely be more effective than your one. ”

Yang Zhongwang nodded and smiled: "The old fox asked the old police officers who are familiar with the case to deal with it, and it is a bit interesting to let the old police officers fulfill a wish." Since you are so confident, then I will not have much to do. I just want to know what you're going to do when that showy brat comes back? ”

Director Han asked puzzledly: "Clean up, why do you want to clean up?" Yang Ju, I feel that he has done nothing wrong, if I am there, I will not only bless the bride and groom, not only give some small gifts, but also manage the bride and groom to like candy. (To be continued......) R1292
