I raised my eyebrows, I was not surprised that he saw through his thoughts, and walked all the way back to his residence from the Public Security Bureau, and indeed had a lot of doubts in my heart waiting for him to solve my doubts, so I let him count them just now. After pondering for a moment, he looked at him silently and asked, "Isn't behavioral criminal psychology all about judging the suspicious signs that appear in cases?" ”

"Wrong! People can't rely too much on academics, because that will become a shackle and be framed in that framework. Simple example: You or I, as well as most people, may deviate from their normal state of mind under a certain environment, a certain occasion, or a certain condition, but will you kill people because of it? ”

I was slightly stunned, and before I could think about it, I heard him ask in a cool voice: "Let's take another analogy: if your father was not killed in a drunk driving accident, but was hit and killed by a drunk driver, would you be so angry that you want to kill that driver?" ”

It all came so suddenly, like a blunt knife stabbing me in the heart, but not into my skin. I asked him, "How do you know?" "I can't do anything else. That incident seemed so far away that it was not in his memory, and he spread it out naked like this, and found that there was no trace of pain, only a dull and slightly sour feeling.

Gao Cheng's gaze was fixed on me, with a deep meaning of concealment, "When I see the news about drunk driving, I will unconsciously frown, there is no anger, and I will silently pay attention to the follow-up reports of the injured." This is side evidence and is not enough to be a proof of psychological profiling, and positive evidence is...... After you became my apprentice, the police department conducted a detailed personal background check on you, and the report was sent to my email. True academic application is what it should be, it can be borrowed, but it cannot be relied upon. ”

Half-pulling the corner of his mouth with a wry smile, he carried out his words and deeds thoroughly, and directly took me as an example.

"Let's talk about Sister Xiaotong's case, do you have an idea?" I decided to change the subject, but Takajo said, "Wrong again!" There is no positive evidence to confirm that the charred female corpse is Xiao Tong's sister, and the identity documents left at the scene, Xiao Tong's identification by the steel nail on his left leg, including the forensic doctor's judgment through bone age, can only be regarded as side evidence to cite that the female corpse is very similar to Tong Ziqi. ”

I stopped talking, and looked at him in silence, was this deliberately going against me?

He slowly and methodically picked up the teapot and poured it for himself, sipping it shallowly, as if he was tasting tea very elegantly. I looked at the qi knot, it seems that he has made up his mind not to open his mouth tonight, thinking about how to issue an eviction order.

I don't think I can be under the same roof with him again, in fact, I took a closer look at the next room that day, except for the kitchen that can't be used, as long as the house is cleaned and cleaned, it can be lived. But I heard a cold voice from the other side: "Don't even think about it, don't think about it until you restore it to the original state, don't think about driving me next door." ”

"Seeming," I said patiently, "next door is your home, and this is my house." If you want to get back to the original situation, contact the decoration company and they will do it for you as quickly as possible. ”

"Two possibilities." Gao Cheng suddenly changed his words, "Tong Ziqi wanted to kill the man, and after luring him up the mountain, he wanted to push him off the cliff, but the strength of the man's prosthetic steel arm was extremely strong, and when he rolled to the bottom of the cliff, he grabbed her left hand and didn't let go, and cut off his arm in order to protect himself." ”

He was finally willing to talk about the case, and he wanted to ask what the second possibility was, but he changed his sentence: "Doesn't it mean that the current evidence can't confirm that the female corpse is Xiao Tong's sister Tong Ziqi?" ”

Annoyance appeared in Gao Cheng's eyes: "You should be asking the second possibility, not this meaningless question." Do I have to say 'that charred female corpse' every time I mention it? ”

I almost couldn't help laughing, but I still didn't follow his train of thought, "Why did Tong Ziqi kill that man?" Can she beat a man as a woman? You say she cut off her arm, what is the tool? How much courage does that take? ”

"Vendetta killings, love killings, conflicts of interest, these are the motives for killing, you have to ask the police. A woman's physical strength may not be as strong as that of a man, but she is better than she is prepared. The courage to cut off an arm is indeed not something that ordinary people have, but compared with life, it can still be traded-off. As for the tools, then you have to ask Tong Ziqi herself. Gao Cheng frowned and explained, and reminded in a cool voice: "You haven't asked me about the second possibility yet." ”

Ignoring the latter sentence, I asked: "How can I ask when Tong Ziqi is dead?" Is the forensic autopsy there to get answers? ”

"Natsutake." Suspiciously burst out of my name, although I didn't see gritted teeth, but his eyes were very intimidating, "The answer is that I don't know, I am a human, not a god, and I can't judge without any obvious traces, not even her stump arm." The second possibility is that you don't ask or not? ”

I thought back to the situation when I saw the stump arm when I fell under the cliff mouth, because it was hidden in the grass, just seeing that it was a human hand, I was frightened, and then there was a sudden change, so I was sure that I didn't see the situation at the broken arm. Suddenly, a light flashed in his mind, staring at Gao Cheng's eyes tightly, "Do you think there is a possibility: the arm I saw under that cliff may ...... It's not Tong Ziqi's? ”

He was silent, but my mind began to churn, and according to his argument, I didn't fully see the arm, but I made a subjective judgment because the female corpse was missing an arm. So is there any possibility: Did Tong Ziqi's arm be broken before he arrived at the scene of the crime, so he couldn't find any murder weapon at the scene?

Subconsciously went to look at Gao Cheng and found that his face was as heavy as iron, so he had to follow his will and ask: "What is the second possibility?" ”

As soon as I asked, he turned away from his dark color, and the corners of his mouth curled: "Go and bring the things." I asked, "What is it?" He threw a cold look over, "I cleaned up and took it myself, and I forgot it?" ”

I was stunned for two seconds before I realized that he was talking about the object I had thrown next door about him. The topic came back to him, and he threw out the bait of the case, intending to let me eat half of it, and hide the remaining half, unless I compromised and agreed that he would stay here, and then I would take out that half, right?

My reaction was to get up and pack up the teapot and teacups, and I didn't look at him, and whispered: "It's not early, tomorrow there will be relevant evidence and witnesses from the police station, I will definitely call you early, go back there and wash and sleep." ”

I won't eat him yet, or he will be able to gain an inch.

But just as I turned around, Gao Chengqian threw a sentence: "The arm is not the key." After a pause, he ignored him and walked to the kitchen, and his voice came from behind him: "The key is the third person." ”

Look back at him! He must know how to fish, a bait makes a haunt work, and he will play a heavier bait, especially if he has more bait hidden in his pocket than you think, there is always a chip that can make your heart flutter. At this moment, he smiled like a fox.

Going back and forth between the two doors, I tried not to think about anything else, my thoughts revolved around the "third person", was Gao Cheng referring to the person who carved the mark? One of the biggest loopholes in the first possibility he just mentioned is that he didn't mention the "third person" who carved a mark on the tree, is this person not at the scene, or is this possibility wrong?

After An Jian stopped, he didn't pay attention to Gao Cheng's smug and arrogant look, and his eyes fixed on his chin and said, "Now you can talk about it." But he said to him, "I'm sleepy, so I'm going to wash and sleep early." ”

I gritted my teeth and looked up: "Chu Gaocheng!" ”

"The voice is an octave high, the speech is clear, and the words are articulated. In this state of boiling emotions, there can be no slackness and difficulty in the academic field. Looking at his calm eyes, and it was difficult to hide the curvature of the corners of his mouth, I really wanted to ...... Punch him.

And he said after lowering his eyes: "I don't really mean who I mean by 'third person', but a kind of traction link, it doesn't matter whether it is on the scene or not, the important thing is that it connects unrelated people and things in a way that connects the past and the future." The same mark, the lost evidence, the ingenuity is here, so you are right, the arm you see in the grass must not be the female corpse, because, it will be the bond next time. ”

I looked at him in amazement, "You mean...... Will there be another murder? ”

He smiled coldly, his eyes were as sharp as a knife: "Above the psychological layer, controlling the overall situation step by step, this kind of pleasure has been eaten and tasted, how can you be willing to stop here?" ”

"Gotta get him out. He left a mark on the scene, and he didn't believe that there was no clue at all. ”

"You still don't understand, I said that this 'third person' is not necessarily the person who engraved the mark, but a person who exists in the void, it may be the marker, or it may be...... The one who never came to the front of the people. ”

Lying in bed late at night, I couldn't sleep for a long time, and all I had in my mind was Gao Cheng's words. After the "third person" assertion, he refused to talk about anything else, only said that he would make a conclusion after the relevant evidence came out, and once again said with a straight face: "I must be responsible for behavioral logic and criminal psychology, and I will not speak again until there is definite evidence." ”

But before I compromised into the bedroom, I heard him whisper as if to himself: "The best fisherman is Mrs. Jiang." ”

After thinking for a while, I realized that he compared himself to Jiang Taigong, and I was the fish that the wisher took the bait. I suspect that the "fishing theory" he thought before was spied on by him, and does the other meaning of Jiang Taigong's fishing imply: the bait can't be lowered at one time, or if the fish is fed, it won't be baited later? <
