Si Fujian smiled faintly and said:

"Lie detectors aren't always accurate. It is useless for spies who have been specially trained and have good psychological qualities, and one of the training programs of the FBI is to train its members to stabilize their minds under polygraph tests. Assuming that Wang Shengsheng is the murderer of Yinledi, then he must be a ruthless murderer with superb intelligence and amazing psychological quality, then it is naturally not difficult to escape the detection of a lie detector, isn't it?"

Su Shu was stunned for a moment, he exchanged glances with the old sheriff, and then looked at Si Fushimi again, and said:

However, Wang Shengsheng also recorded a confession. Moreover, he himself had a witness who gave a statement as a witness. Suspicion has been ruled out......"

"I know, it's Wang Shengsheng's classmate Jin Na, right?" Si Fushijian smiled, "I also checked the information of that little girl, and found that she and Wang Shengsheng's past friendship is not shallow." I also read Wang Shengsheng's confession, which is very interesting, in the confession, Wang Shengsheng said that he and Jin Na were childhood sweethearts, and the two wandered the street for an afternoon to buy clothes. Jinna's testimony and Wang's own testimony are as consistent as a script. I am very strange that at that time, not long after Wang Shengsheng's sister passed away, his psychology was full of hatred, but he was in the mood to wander out with his pro-plum girlfriend for an afternoon to choose clothes with his female classmates, isn't it very abnormal?"

"This ......" was analyzed by Si Fujian, but Su Shu was speechless. "So, what do you think...... Did the two of them collude to get their lines right?"

"It has to be. Fushimi smiled slightly. "If the relationship between Wang Shengsheng and Jin Na is close to the level of boyfriend and girlfriend, it is not a strange thing for Jin Na to exonerate Wang Shengsheng. To find out whether the confessions of the two men were fake or not, I had a very simple plan. ”

"What...... Strategy?"

Fushimi smiled and said:

"I called Wang Shengsheng and told him that our police confession was lost due to an accident, and I wanted him to come to the public security bureau to re-provide the testimony of Yinledi's case. For normal people, two months have passed since the incident, and the specific details of that day must have been forgotten, including the details of shopping and shopping, after all, if the person who did not commit the crime provided testimony, almost no one would forcibly write down their own testimony, and once the suspicion was exonerated would be forgotten. But if Wang Shengsheng is a murderer, and the script is written in advance, before Zhang Guohua's execution, he will inevitably be more nervous and cautious, presumably the original script is still retained, and the details of the events of that day are extremely clear, if we re-record Wang Shengsheng's confession, his confession is as accurate as the script two months ago, it will be very suspicious......

"This ...... It seems to make some sense. But at best, it only increases suspicion of him, right? and...... Even if Wang Shengsheng was really a murderer, how did he manage to kill people......? I can't explain it. Su Shu asked with a frowning sword eyebrow.

"Yes, this is the most complicated part of the Yinledi case. Si Fushimi nodded slightly, "Everyone's death clues are intertwined, inseparable, and confusing. But...... If you think outside the normal frame of mind and think from a different angle, it is very simple. ”

"How so?"

"I wonder if Miss Su has ever heard of 'hypnosis' or 'mind control'?" said with a smile.

"Could it be that you want to designate the murderer as a superpower? Let's believe in that kind of absurd mysticism?" Hearing Si Fushimi's mention of hypnosis and mind control, the old sheriff suddenly had a seizure, his eyes widened, and he glared at Si Fushimi.

Si Fushimi smiled bitterly and said:

"It's just the most likely reasoning. Hypnotism is a secret technique that has a long history, even in China, and is mentioned in the Neijing. Moreover, this occult art is often associated with religion. Of course, to explain it scientifically is more of a superstition and deception. If Yinledi's quietness is attributed to hypnosis, then all the clues are reasonable, and all the doubts are solved. ”

"Of course, if it's not mind control. I can only attribute it to special threats or drug control. For example, the famous psychedelic drug 'Devil's Breath', which is extracted from the 'Boracelo' tree in South America, has the ability to manipulate people's hearts and temporarily lose their memories at the mercy of others. ”

Si Fushimi's is worthy of being an internationally famous detective, and his breadth of knowledge is not comparable to that of ordinary criminal policemen, and even what kind of psychedelic drug devil's breath Si Fushimi said, Su Shu has never heard of it at all!

"It's still hard to believe...... Su Shu looked at Si Fujian with some disbelief, "The last thing we can believe in as police officers is what kind of demons and monsters, and besides, we can't use any hypnotism to exonerate Zhang Guohua, right? ”

"But what if we have enough evidence?" Skushimi smiled, "I can make such a judgment, and naturally there is a way to make the murderer reveal his feet with hypnosis in front of all of us." ”

"......" Si Fushimi's words full of self-confidence once again made Su Shu and the old sheriff look at each other.

Si Fujian said with a smile: "Let's talk about the incident of Zhou Nanping, the director of the Construction Bureau, being broken into his home after the Yinledi case." This incident is also directly related to the demolition of Li Yujiang's house. Although Zhou Nanping's family did not have a very clear impression of the break-in incident, the surveillance camera in Zhou Nanping's home still captured a picture of a suspicious person. ”

As he spoke, he walked over to the desk and sat down, then took out a tablet from the satchel he was carrying, laid it flat on the desk, and quickly opened one of the videos.

At Si Fuji's signal, Su Shu and the old sheriff both came to the front of the desk and stared at the video screen on Si Fuji's tablet.

"Please take a closer look, this is the video material left by Director Zhou's house when it was invaded by a mysterious person that day. The man was dressed very ridiculously and suspiciously, he was wearing a black raincoat and a foil helmet, apparently not wanting people to know his identity. ”

On the tablet, a tall black figure is slowly walking through the picture of the surveillance camera, but the camera picture is very blurry, and the figure disappeared after walking less than four steps in the camera.

The surveillance screen is only about ten seconds, including the two screens of the mysterious person entering and exiting, and the total time that the mysterious person stays in front of the screen is less than twenty seconds.

"Do you see what?" After the video was played, Si Fujian put his hands on his cheeks and looked at Su Shu and the old sheriff with a smile.

Su Shu and the old sheriff had very different faces, one was confused, the other was cautious, but in the end, they ...... Both men shook their heads.

"It's so blurry that you can't see anything......! Let's get straight to the point. Su Shu looked at Si Fujian with some shame.

Si Fushimi smiled slightly:

"It's a blurry picture, but I'm getting some information. First of all, intuitively, the intruder is between 1.88 meters and 1.9 meters tall, but it is clear that he deliberately wore heightened insoles and helmets to hide his height, however, he still gave me a certain standard. His raincoat hides his figure, and I can't tell his exact figure from the video. However, the most important thing is the distance between his legs, his walking posture and the distance between his steps. ”

"Walking posture, step spacing?" Su Shu said in surprise.

"That's right. Everyone's walking posture is different, this is true for men, and even more so for women. There is a specialized discipline that analyzes the way people walk. Shifushimi said with a smile, "The distance between each person's steps, the distance between the hips and the frequency of hip swings, the length of the legs, and the length of the knees and thighs are all details of the investigation. Especially women, not to mention women and little girls who have given birth, that is, women and virgins who have generally had a higher frequency of sexual intercourse will have subtle differences in waist swing, hip swaying, calf and step frequency. ”

Speaking of this, Su Shu, a policewoman with excellent psychological quality, actually flashed a blush on her face, but she bit her lip, but she didn't say anything, just her eyes flashed.

Seeing Su Shu's shy appearance, Si Fu smiled and continued:

"From the video footage, this intruder is not a soldier or a police officer, nor is he a gangster. Because soldiers and police officers have been trained to walk in a more firm and steady manner, the spacing of their steps will also be mechanically biased towards similarity. And this character in the video is obviously not, he walks in a very stable posture, with a fast frequency, and his legs are relatively slender, and his thighs are even and not thick, much like a young man, or even a student. Judging from his hip and hip structure and gait, he should have a good figure, because obese people walk with their arms not easy to swing, and the center of gravity of the body will also be tilted forward. The ratio of leg length to step spacing is 3:1, which is the most comfortable state of the human body, compared with the floor lattice on the ground, it can be seen that his step spacing is about 3.5 to 4 cm, and the middle is 3.8 cm, that is, his leg length is about 1.14 meters, and the navel eye is the golden section point of the human body, divided by 0.618, it can be calculated that the height of this mysterious person is between 1.83 and 1.85 meters, which is very consistent with the height of Wang Shengsheng. ”

Speaking of this, Si Fushi paused and said with a smile:

"And I compared the video data when Wang Shengsheng took the confession, and found that this mysterious person's walking posture, step spacing, and height data are all very consistent with Wang Shengsheng, so ...... It's him, you can't be wrong. ”

After speaking, Si Fushimi's eyes flashed with unprecedented affirmation and confidence.

On the other hand, Su Shu and the old sheriff looked at each other and were dumbfounded.

[The sixth watch is sent, the flowers do not move, what is the rhythm of this?]
