After 100,000 simulated crimes, I became an ace detective.

The truth can also be a lie.

What Bai Yu said made everyone present stunned.

Lan Jing, who was sitting next to her, held the side of her black-rimmed glasses with one hand and nodded thoughtfully.

"There is such a possibility."

"In psychological criminology, there is a montage-style lie. Although everything the suspect says is true, the results have different effects because of the different order."

"A sentence can be divided into three paragraphs: A, B, and C. Originally, the normal cause and effect were A+B+C, but in the end, the criminal suspect used the transposition word order of B+C+A, or C+A+B."

"As a result, the meaning of the entire sentence changed, but it happened to be true."

"This may be difficult to understand. Let me give you the most classic case: She divorced me and was with someone else, so I beat her."

"This sentence, as a whole, makes the narrator seem to be in a weak state, which makes people secretly sympathize with him and makes it easier to forgive him when he is sentenced."

"However, this is actually a lie in a changed order. The real cause and effect is...because I beat her, she divorced me and was with someone else."

"This is a montage-style lie, which can cause each sentence to be true, but when combined out of order, it will bring completely different meanings and results."

After listening to what Lan Jing said.

Lin Tian, ​​Huang Qiang and others sitting next to him were all deep in thought, seeming to be recalling the previous interrogation about Zhang Lifang.

after a few seconds.

Lin Tian shook his head gently, then frowned and tapped the table.

"wrong."

"Although montage-style lies exist, judging from Zhang Lifang's state just now and her words before and after, this should not be the case."

Speaking of it.

Lin Tian cut the surveillance video in front of him to the middle position, where he was asking about Zhang Lifang's status, and pointed to everyone present to take a closer look.

When the brief interrogation process was played again.

Although Lan Jing was the only person present who had a PhD in criminal psychology, they were all very proficient in criminal investigation and had extensive experience, including even the director of the Nishimei Criminal Investigation Brigade.

Naturally, we have some understanding of montage lies and can roughly judge whether this situation exists.

Liu Yang, who had just arrived in the conference room not long ago and had not participated in previous interrogations and had no preconceived notions, nodded in agreement and further confirmed.

"It's really no problem."

"Judging from the video of this interrogation alone, let alone the old man who didn't speak at all and was completely in his own spiritual world."

"Then, about the words of the other nanny, the words she said, even if the order is rearranged twice, there is no way to get any effective information."

"In other words... there is no need to regroup at all to form a montage of lies."

Even Liu Yang is so sure.

Everyone present completely understood that the montage lie did not exist in this case.

Bai Yu squinted his eyes slightly, stared at the surveillance video in front of him, knocked the pipe in his hand, looked around at everyone present and said.

"In addition to montage lies, there are actually two other ways."

"There was one such case in the mystery works I read. Although the suspect told the truth, he did not change the word order and used montage techniques."

"But as long as...the criminal suspect deliberately conceals some words and hides some important information, it will also leave us completely confused."

"It's like a murderer. We approached him to ask about the specific case, and he said he was a witness, not the murderer."

"When the information is unequal and no clues are found, will we trust his unilateral words more and not deeply suspect that he is the real murderer?"

"Because there is no evidence, we are missing the most important piece of evidence."

"When the murderer is hiding something and we are revealing it, and when we are sure that we have not exposed any clues, we can deliberately point out the wrong path."

"It takes us away from our search direction and wastes our precious time."

Speaking of it.

Bai Yu paused for two seconds, then his eyes became more serious and sharp, and he continued to talk.

"And there is one final situation."

"That is... Zhang Lifang told the truth, and she did not deliberately hide it, but the key problem is that she actually doesn't know much at all."

"I personally feel that if it is combined with this drug trafficking organization, it may be the most likely scenario, and it can also well explain the issues in this interrogation."

"A more appropriate explanation would be..."

"Although Zhang Lifang was the spy arranged by K, she didn't know that the pastor was Jiang Sulong. In other words... the pastor's true identity was not exposed."

"Maybe the pastor once told Zhang Lifang to take care of Yu Ruyi with all her heart, but not as a son, maybe as a relative."

"Or maybe he used his sister Jiang Sumei as an excuse to show that in order to protect the safety of contraband, Yu Ruyi must be taken good care of."

"You can even just give the order without giving any reason."

"This creates a unique situation."

"Perhaps Zhang Lifang is indeed the spy of the drug trafficking organization, or even a core member, and knows many internal things."

"But all she needs to do is, she doesn't know the relationship between the pastor and Yu Ruyi, she doesn't know the pastor's real name, let alone other related things."

"Then, in the first interrogation, she will definitely be able to easily avoid all the minefields, and then make arrangements to escape after leaving the police station."

"She, or K, captured the characteristics of our police interrogation. Perhaps it is more appropriate to describe it as weakness."

"During the interrogation, our police will not go into too much detail about the case because they have not obtained any important evidence, out of the desire to keep the case confidential and for fear of involving innocent people."

"Just like in this interrogation, Bureau Lin, Bureau Huang and Bureau Wang were all asking Zhang Lifang about Jiang Sulong. They did not mention the word pastor at all, or anything about drug trafficking organizations."

"Because, based on Zhang Lifang's previous performances, you subconsciously believe that she, who is so familiar with nanny work, should not be an informant planted by a drug trafficking organization."

"So it is normal to avoid this part of the matter during interrogation."

"It can only be said that Zhang Lifang is good at capturing the weaknesses of human nature and is more aware of our police's case-handling techniques and procedures."

"And the confidential handling of cases, although very useful, sometimes seems too serious and useless."

Zhang Lifang is a member of a drug trafficking organization.

But I don’t know the relationship between the pastor and Yu Ruyi, nor the pastor’s true identity Jiang Sulong.

Bai Yu's conclusions drawn from his reasoning works stunned everyone present.

After two seconds.

Huang Qiang, who obtained relevant information from Sister Bomb and chased Lin Tian all the way from Taicang City to Jinling, rubbed his calloused fingers.

"possible."

"Judging from the level of secrecy of this drug trafficking organization, it is actually very possible for each member to not know each other's true identity."

"In addition, the pastor is the real core figure, and K has a close relationship with him. It is very possible to recruit an informant to take care of his mother."

"As for handling cases confidentially, it does have certain flaws, but in the end it does more harm than good."

"But the problem now is..."

"Detective Bai, how are you sure that we will let Zhang Lifang leave?"

"According to what you said before, as long as we don't let Zhang Lifang leave, if we continue to interrogate her, we will always find flaws and questions."

heard here.

Bai Yu was silent for a few seconds, feeling somewhat uncertain for no reason.

But the next second, he thought of the various techniques he had learned from Su Ming during this period, as well as the confident expression and eyes as long as he deduced the result.

I can learn so many techniques and all kinds of criminal investigation knowledge from detective works.

It is enough to prove Bai Yu's talent and outstanding learning ability.

During this period of time, Bai Yu, who was studying seriously next to Su Ming, clearly felt that his logical deduction ability had improved rapidly, and he had the confidence that he would not be shaken once he had deduced the results.

Take a deep breath.

Bai Yu imitated Su Ming's state, without showing any expression on his face, and tapped his pipe with a calm but extremely confident expression.

"I think......"

"If Zhang Lifang can be sure that she will be able to leave the Criminal Investigation Brigade after the first interrogation."

"Then the problem must be with Yu Ruyi."

"For such an old man with severe Alzheimer's disease who is not aggressive, we will always maintain sympathy for him, and we will subconsciously relax our inner guard."

"Just like walking on the road, we are always unprepared for the elderly and children, so we are often deceived."

"Using Yu Ruyi to escape from the Criminal Investigation Brigade, this is the origin of Zhang Lifang's confidence."

Wang Qi, who was also present in person at the previous interrogation of Zhang Lifang, clicked his tongue in confusion and frowned.

"its not right."

"How could Yu Ruyi help her? Or rather, how could she help Zhang Lifang?"

"During the interrogation just now, Bureau Lin and Bureau Huang both saw with our own eyes that Yu Ruyi's state was clearly not an act. Alzheimer's disease was very serious visible to the naked eye. He was immersed in his own world and could not listen to anything at all. talk."

"How can I help in this situation? I don't care..."

Before Huang Qiang could finish speaking.

Lin Tian, ​​who was sitting next to him and was always thinking, suddenly thought of a possibility.

He immediately picked up the mouse and adjusted the surveillance video to the end, which was the part where he learned that Jiang Sumei might be the breakthrough point.

after a few seconds.

In everyone's sight, they could clearly see Yu Ruyi wielding the peach wood sword.

He suddenly stopped moving, looking embarrassed as he couldn't hold back his urine.

But there was no expression of shame or fear on her face, only confusion and confusion.

This can be completely confirmed that Yu Ruyi's severe Alzheimer's disease is definitely not pretending, and he certainly cannot pretend to be like this.

Especially the expression of confusion and confusion is no different from the state of a child peeing its pants.

If the problem is not with Yu Ruyi, then it is with Zhang Lifang?

thought here.

Lin Tian turned his eyes and attention to Zhang Lifang in the video.

Discover......

Zhang Lifang was talking to them at the time and did not pay attention to Yu Ruyi at first.

Isn’t the problem not with Zhang Lifang?

Lin Tian leaned on the chair, frowning, sniffing the smell of tobacco on his index finger, and Zhang Lifang's last words rang in his ears.

"Three officers."

"Sorry, sorry."

"Then I'll go home first, then I'll take Sister Yu home first."

......

As the video ends.

Lin Tian still didn't find any problem, but he felt something strange.

There was something unspeakably weird, especially after Bai Yu's words before, Lin Tian seemed to feel that this interrogation was actually arranged by Zhang Lifang.

Not much to say.

Lin Tian continued to play the last part of the surveillance video repeatedly, and Zhang Lifang's previous words were heard.

"Three officers."

"If there is nothing else to do for the time being, do you think...can I take Sister Yu home first?"

"I've been out for a while now. If I don't go home quickly, I'm a little worried that Sister Yu won't be able to hold it in anymore..."

And just after she said this.

Yu Ruyi really couldn't hold it in, making her whole person's condition extremely embarrassing.

After Zhang Lifang finished speaking, Yu Ruyi was like this?

Now that Yu Ruyi's condition can be determined, she must not be able to actively cooperate with Zhang Lifang, and she is immersed in her own world.

If under such circumstances, it is still necessary to say that Yu Ruyi can cooperate with Zhang Lifang, the only possibility is...a subconscious reflex?

It's like training a dog.

With repeated training, the dog can make commands such as sit down, shake hands, and lie down as soon as it hears the command.

But Lin Tian did not make a judgment immediately, but continued to watch the surveillance video.

At the last moment, he set his sights on Yu Ruyi.

When Zhang Lifang's last words were heard again.

Lin Tian had clearly seen that Yu Ruyi, who was originally confused and at a loss, had his legs shaking again.

this moment.

Lin Tian suddenly narrowed his eyes and clenched his fists subconsciously.

Without the slightest hesitation, Lin Tian replayed the scene just now.

This time.

Lin Tian already had a goal in mind, and he knew very clearly that maybe the problem lay with Zhang Lifang.

This is the third time it has been played.

After a few minutes.

Lin Tian stood up without hesitation and said suddenly.

"Yu Ruyi is under control,"

"There is something wrong with Zhang Lifang! She is K's spy, arrest her immediately!!!"
