"And just now, when you interrogated him, I looked into his background, and the results confirmed my judgment even more."

"According to his academic qualifications and past colleges, he has been studying alone in other provinces since he was a child, and his parents even died in an accident later, so his childhood lacked the warmth of the family, which made his personality very indifferent."

"During his time at school, although he was not yet arrogant, his character may not be much better according to many disciplinary records, and even once he violated discipline, he was sent to the hospital by his classmate, or his father relied on high compensation to suppress the matter, and the school did not expel him."

His family is very wealthy, and it is this kind of rich second generation who has money and no one cares about it that is most likely to cause mental illness. If they are not treated in the accumulation of years of accumulation, the possibility of psychopathology is very high, which has one thing in common with most criminals, that is, the unhappiness of childhood and the unsatisfactory real life of many years, and the violence inflicted on others is their biggest regulator. ”

"When I went to college, this violent tendency suddenly disappeared, not because he became better or sensible, but because as he got older, his control also became stronger, and this mental illness was well hidden."

As experts in psychology, especially in the field of criminal psychology, the two have no objection to Gao Qilu's analysis.

Wang Gang asked solemnly: "You mean that he is actually a well-hidden psychopath?" ”

Gao Qilu nodded: "Yes, this is also consistent with the character portrait of the murderer." ”

Wei Xiao hesitated for a moment, still defending Wen Tao: "But this doesn't completely mean that he is the murderer, right?" ”

But Gao Qilu keenly noticed the loosening of Wei Xiao's position, so he continued: "Of course, what I said is just the motive for his crime, the real evidence is because I found that his bookstore is very close to the location of the four victims, and the location of the bookstore Wei Team should also be clear, and it is right in the center of several murder scenes." And he closes before 9 o'clock every night, according to the street surveillance, the two days even closed at 8 o'clock early, and he did not have an alibi during this time, which is very consistent with the time and distance of the victim's murder. ”

"And as a bookstore owner, it's easy to learn criminal methods and physiological structures from books."

"Now that he has the reason, the knowledge, the time, and the right place to do these things, I have no reason not to suspect that he is the real murderer! In the case that the murder weapon can no longer play the role of evidence, now we should find the 'witness' and complete the last piece of the puzzle against him, before that, we still need to keep an eye on him, if he can't resist the desire to kill while we are collecting evidence, then it is just right to arrest him directly. ”

Gao Qilu was full of confidence, as if Wen Tao was already in his pocket.

Wang Gang and Wei Xiao glanced at each other, and the two of them secretly said in their hearts: "It's done." ”

Gao Qilu has thoroughly believed in the existence of "witnesses".

Wei Xiao spoke: "Wen Tao's side is up to me, he is less wary of me, and there are more chances to pry out the identity of that witness from his mouth." ”

"Then I will be responsible for collecting and analyzing data and other evidence, and it will take a lot of time to visit." Wang Gang also answered.

"Then I can ......" Gao Qilu was about to say to assist them in their analysis, but was interrupted by Wang Gang as soon as he spoke.

Wang Gang looked apologetic: "Doctor Gao, please understand, after all, you are also one of the suspects now, and we can't let you participate in the investigation of the case." ”

Gao Qilu suddenly nodded to indicate that he understood, but he was relieved in his heart.

The reaction of the two of them is normal.

Wang Gang seemed to have always trusted himself before, but in order to confuse himself, this reaction now is the reaction to dispel his suspicions. This also made Gao Qilu let down the guard in his heart, as long as they found the witness first, he could sit back and relax.

I have to say that although Gao Qilu has a high IQ and is good at capturing details, this just gives Wei Xiao and Wang Gang the opportunity to grasp his nature and influence his judgment through progressive changes in language and psychology.

This was also discussed by the two a long time ago.

Originally, in the psychological game, Gao Qilu should not have lost to Wang Gang so easily, even if he was not as good.

But he didn't know that the two people on the other side had not only begun to doubt themselves a long time ago, but had even laid a trap waiting for him to drill down. And because the other party knows his own thinking mode and uses the advantage of information asymmetry to perform a play against his own character, Gao Qilu is naturally believed to be true.

Just like Wei Xiao's change in language and demeanor from being biased towards misunderstanding to believing in Gao Qilu's analysis, it not only made Gao Qilu sure that Wei Xiao was not Wen Tao's person, but also determined that what he said was difficult to distinguish between true and false, which made the two trust themselves more.

And in the end, Wang Gang's adherence to his principles is not that he doesn't believe in himself, because Wang Gang is usually a person with principles in a sleek manner, so this refusal is a normal performance, and because there is no abnormality, it shows that he still has a considerable degree of trust in Gao Qilu, but it is precisely because of trust that he has no intention of using this witness to force himself to make a move.

As everyone knows, no matter how alert the fox is, it can't compare to the acting skills of a hunter comparable to Oscar.

Because of insufficient evidence, Wen Tao and Gao Qilu were quickly released, and Wen Tao came out early and waited for Gao Qilu in the courtyard.

When Gao Qilu passed by, he whispered in a resentful tone: "I know that you are the murderer, but I have enough evidence to convict you, and when I find out who I can trust in the police system, you will die!" ”

Gao Qilu was disdainful in his heart, the person in front of him didn't understand the law at all, but in order to prevent the existence of the eavesdropper, he just sneered and said, "Don't worry, I will soon send you to prison while proving my innocence." ”

After saying that, he didn't say anything more and turned to leave, and the two of them didn't have anything to say.

From the exchange of smiles when the two met for the first time, to cursing each other at this moment, it has only been a day, and this is also the second official meeting between the two.

Listening to Wen Tao's curses to himself behind him and the imperceptible panic in his words, Gao Qilu raised the corners of his mouth proudly.

So he couldn't resist the pressure for long to be able to say who the witness was, right?

Looking at Gao Qilu's back gradually moving away, Wen Tao stopped his shrew-like performance, chuckled at the corners of his mouth, and wondered when he should not be able to resist the pressure to tell who the "witness" was......
