Criminal psychology is a thing that every police officer has taken more or less when he goes to the police academy. Pen & Fun & Pavilion www.biquge.info sometimes used in the actual solving of cases, to figure out the psychology and behavior of the criminal, as an auxiliary means of reasoning.

But Fang Qing really hadn't seen this thing.

Let's hear about it. Fang Qing and several criminal policemen exchanged glances with each other. That Bo Jin Yan looked calm and continued to sit and drink tea. It seems that he has seen a lot of criminal police officers like them and such scenes.

The midnight wind was quiet, and while waiting, everything seemed extraordinarily quiet. Fang Qing noticed that Jian Yao had already sat down next to Bo Jinyan and turned on the computer. Bo Jinyan lowered his head slightly and said something to her. Jian Yao nodded, her serious and indifferent appearance was the same as Bo Jinyan. The way the two of them got along suddenly made Fang Qing think of a word: talented and beautiful.

In fact, when was Fang Qing also looking forward to such a love, having a gentle and lovely woman to accompany him.

However, the woman he fell in love with later was an eagle.

Fang Qing smiled self-deprecatingly.

At this time, Bo Jinyan spoke: "He is a local, or has lived in the local area for quite some time. And it is a solitary crime, aged 20 years and older.

He was someone who the deceased Fu Wei knew, or at least someone who had contact with him in the ancient city.

On the night of the crime, he wore a thick coat, which he later discarded.

He has a certain sense of anti-investigation, and has mastered some practical anti-investigation skills, and seems to be more familiar with the police case-handling process. It is likely that he had dealt with the police in other cases. For example, he has been investigated by the police as a suspect or related person.

He lived within a few blocks of the incident and did not have the conditions to live alone.

He has no job, or is in a lower-level job.

He acted boldly and meticulously and well-planned, but he was also extremely depressed and showed signs of schizophrenia, but he was strictly self-controlled in his work and life, and was not known. There must have been something in the environment that had a significant impact on his life and caused him long-term stress.

After Fu Wei arrived in the ancient city, among the people he had come into contact with, that is, the group of people you have already checked, focus on looking for people who meet the above conditions, checking their alibis, and looking for eyewitnesses. You'll reap the rewards soon. ”

――

The criminal policemen were all silent, and Fang Qing was also pondering.

In Bo Jinyan's reasoning, there are some of them that he also has the same judgment. But it's more of an old detective's intuition, not as determined as he is.

And Bo Jinyan paused, and it seemed that his attitude did not change in any way because of the silence of the criminal police, neither humble nor arrogant, and calmly began to explain:

"At the time of the crime, it was late at night and it was raining heavily. Fu Wei returned at night, and we all know that there was no cover at the scene of the crime. So the murderer was waiting for him right there.

A thick coat is enough to hide a knife with a total length of 20-30 cm.

Fu Wei left half a palm print 4 meters away from the killing point. The palm lines are clear, the force is even, and there is no blood around it. So this is what was left behind while he was still alive. He had been to a bar and had a drink that day. With such a heavy rain, why did you stop at a distance in the rain and still hold your hands on the wall? Because he saw people he knew, or at least people he had seen in the ancient city.

Not strangers. When you see a stranger on a rainy night, even if you think it is strange, you will only pass by and will not stop for him.

Fu Wei's wrists have signs of fighting, and the murderer's wrists, face, and other exposed skin may have been scratched by Fu Wei.

The killer was very familiar with the distribution of surveillance cameras on these streets, the direction of the road, the time when the shops opened and closed, and the abandoned elementary school. Indicate that he has lived in the local area for at least some time. There are no accomplices, because if there were two people, with the thoroughness and boldness of the murderer, they could have taken a more perfect way of committing the crime, without having to run to the elementary school to change the bloody clothes, and lead to leaving traces.

He was so brutal that he almost lost control of the corpse, slashing more than forty times, and not for the purpose of disguising the corpse's identity and key features. Calm and angry, restrained and crazy, such a contradictory expression must come from the extreme mental distortion after a long period of repression. His life was unsatisfactory. He kills people in such a rude, simple way out of instinct. Such a person would not be engaged in a job that requires complex intelligence and interpersonal skills in reality. In his mental state, he couldn't do it either.

He left in a hurry after changing clothes at elementary school. There was no lingering, for with his prudence, if he stayed, he would inevitably find traces of blood and clean it up. But I just asked your people to check the surveillance within one hour of the incident, and there was not a single suspect on the road from the direction of the elementary school, carrying a bag, soaking wet hair, medium size, and walking in a hurry. So, he lived within the confines of those streets. Now, you can ask questions. ”

A criminal police officer said: "Professor Bo, I think the person you described is a bit contradictory. He was well-planned, a master of crime, like a cultured man, but also rude, and a low-level ......"

Bo Jinyan smiled: "Yes, contradiction." Isn't the irreconcilable contradiction the root cause of crime? ”

This sentence caused the criminal police to ponder. Another detective asked, "Why are you sure that he was wearing a thick coat at the time, and if he wanted to hide a knife, he could carry a bag, and it wasn't just the clothes he was about to change?" ”

"In a bag? When the target comes, unzip it first, then take out the knife, and then slash the person? And also at the risk of the backpack shoulder strap becoming a victim counterattack tool? No, how can our murderer be so stupid? ”

This made the criminal policeman blush, Bo Jinyan's eyes were shining, Jian Yao next to him coughed lightly, his eyes lit up, he was silent for a while, and said to the criminal policeman: "I'm telling the truth, not laughing at you." ”

Interpol: "......"

Jian Yao: "......"

"Professor Bo, do you think the murderer is a man or a woman?" Fang Qing suddenly asked.

Everyone was surprised, and even Jian Yao raised her head. Women? She had never thought about this possibility.

Bo Jin Yan stared at Fang Qing and smiled: "Oh, you asked a good question. Is 'he' a man or a woman? At present, there is no gender orientation in this case. So I think he's a man of medium size, or a woman with enough strength. ”

――

After the meeting, Bo Jinyan took Jian Yao away. Leaving Fang Qing and a few brothers to ponder in the office.

"Boss." Someone asked, "Are we going to follow the portrait made by this professor and go to the suspect?" ”

Fang Qing took a puff of cigarette and said, "There are never too many ways up the mountain. We were asked to solve the case in a week, and now it's been 24 hours. Urge the city's forensic department to give us the results of the identification of the murder weapon and the traces at the scene as soon as possible. Continue to search for the whereabouts of the murder weapon and check the surveillance, but we cannot relax. Then according to what Professor Bo said, go through all the subjects that have been investigated again. ”

"Boss, we've never relied entirely on criminal minds to solve crimes, in case ...... According to what he said, what if the suspect can't be found? ”

Fang Qing smiled and said, "Can't find it?" That's when he farts at us. ”

――

Bo Jinyan and Jian Yao still returned to the Yao Family Inn. They lived in a room on the second floor, and as soon as they entered the room, Jian Yao was hugged by Bo Jinyan.

"Don't hug around." Jian Yao resisted, "I haven't washed my hands, I went to the scene just now." ”

Bo Jinyan didn't let go, and whispered in her ear: "Shh...... Be quiet, don't be heard by the murderer. ”

Jian Yao was stunned.

Fu Wei lived in the Yao Family Inn, and his whereabouts were clearly grasped by the murderer. So, perhaps, the murderer is also in this inn. ”

Jian Yao had a black line: "Then you didn't say it earlier, and you came back to live with me?!" ”

Bo Jinyan let go of her, walked to the side of the bed and lay down lazily: "Do I still want to avoid the suspect?" ”

Jian Yao: "......"

That's not the logic.

Well, she's also calm, isn't she a suspect in a murder case. She walked over and kicked him lightly in the leg: "Hey, go wash your hands, change your shoes and clothes, and lie down again." ”

Bo Jinyan obediently stood up, walked to the entrance, hung up his suit, bent down to change into slippers, and finally walked to the pool to wash his face and hands.

It's like being at home.

It's almost dawn, close the curtains, lock the door, and leave only a soft antique table lamp next to the bed, which is also a safe and intimate small space for each other. Bo Jinyan was more enthusiastic tonight than usual, and he entered her deeply. Then when she put her hands on his chest, unable to lean on, he lowered his head and kissed her face and body inch by inch. In fact, Jian Yao never told Bo Jinyan that such a move always moved her deeply, and it didn't matter about sex. Because she can always feel that he cherishes it sincerely and unabashedly.

If a man always kisses you religiously, then he really loves you.

After the incident, Bo Jinyan routinely asked the parties how they felt: "Are you satisfied?" Has there been a surpass to the last time? ”

Jian Yao looked at him in the misty light, her eyes like gentle stars: "Jin Yan, I think this is your most manly time." ”

Bo Jinyan thought for a while, and actually smiled: "Are you praising me, or are you scolding me?" ”

Jian Yao was stunned for a moment, but also reacted. She meant to praise him, okay? This guy is good at emotional intelligence.

The two of them slept until the afternoon, and they didn't have to worry about the case, and there would be an echo when they advanced. In the evening, the two walked around the ancient city, ate some local specialties, and went back to the inn.

At the beginning of the lanterns, the two stood in the corridor on the second floor, quietly watching. You can see the ancient city wall in the distance, and you can also see the lights by the river, and the scenery is very quiet and warm. This is also what Jian Yao is looking forward to on this trip - if there is no brutal murder, it will be even more perfect.

"It seems to be the courtyard where the innkeeper lives." Jian Yao pointed outside the compound. In fact, the two courtyards are connected, and the other one is smaller and equally green. A small courtyard house, a two-story building, with more than a dozen rooms lit up.

"I heard that a whole family lives there, and the boss, the proprietress and the aunt, and the cousins ......," Jian Yao sighed, "It's good to live in such an old house." The family was not separated. Independent courtyard, gray tiles, white walls, green trees, ancient wells...... The slow rhythm is probably the quiet years. ”

Bo Jinyan looked at her: "I know that you like such a house, we will ...... in the future" suddenly stopped, and Jian Yao was also slightly stunned.

Because in the courtyard opposite, the rooms that were originally lit suddenly went out as if they had been agreed. In all directions, there was an instant silence and darkness. Only the shadow of the lone tree in the courtyard was still gently swaying in the moonlight.

Bo Jinyan frowned.

Jian Yao asked, "What's wrong?" ”

"Nothing," he said. ”
