Criminal psychology is something that every police officer chooses more or less when he attends a police academy. In actual cases, it is sometimes used to try to figure out the criminal's psychology and behavior as an auxiliary method of reasoning.

But Fang Qing has never seen an expert.

And listen to me. Fang Qing and several criminal policemen exchanged glances with each other. The thin Jin Yan was a calm head and continued to sit and drink tea. As if they were such a criminal policeman, such a scene, he saw more.

The midnight wind was quiet and everything seemed extra quiet while waiting. Fang Qing noticed that Jian Yao had sat down beside Bo Jinyan and turned on the computer. Bo Jinyan bowed her head slightly and said something to her. Jian Yao nodded, earnestly and indifferently, just like Bo Jinyan. The appearance of the two of them suddenly reminded Fang Qing of a word in his head: gifted and beautiful.

In fact, when was Fang Qing also looking forward to such a love, there was a gentle and pleasant woman to accompany herself.

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

Fang Qing smiled at herself.

At this time, Bo Jinyan said: "He is a local, or has lived in the local area for quite some time. He also commits crimes alone and is over 20 years old.

He was someone the fuer knew, or at least someone who had contact in the ancient city.

On the night of the crime, he wore a thick coat and discarded it.

He has a certain awareness of anti-investigation, and has mastered some practical anti-detection skills. He seems to be more familiar with police procedures. He is likely to have dealt with the police in other cases. For example, as a suspect or related person under police investigation.

He lived within a few streets of the incident and did not qualify for solitary living.

He has no job or is engaged in lower-level work.

He acts boldly and meticulously, and has a well-planned plan. However, his spirit is extremely depressed and there are signs of schizophrenia. However, he strictly controls himself in his work life and is unknown. There must be something in the environment and something that has a significant impact on his life, causing him long-term stress.

After Fu Wei arrived in the ancient city, among the people who have been in contact with you-that is, the group of people you have already checked, the focus is on finding people who meet the above conditions, verifying their absence certificates and looking for witnesses. You will soon gain something. "

——

The criminals were quiet, and Fang Qing was contemplating.

Some of Jin Jinyan's reasoning had the same judgment. But it was more the instinct of an old criminal policeman, not as determined as he was.

But Bo Jinyan paused. It seemed that his attitude did not change in any way due to the silence of the police officers.

"At the time of the crime, late at night, heavy rain. Fu Wei returned home at night, and we all knew that there was no shelter at the point of the crime. So the murderer was waiting for him.

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 killed point. The palm print is clear, the force is even, and there is no blood stain around. So this is what he left while he was alive. He went to the bar that day and drank. With such a heavy rain, why did you suddenly stop at a distance in the rain and still support your hands on the wall? Because he saw people he knew, or at least people who had met in the ancient city.

Not a stranger. When you see a stranger on a rainy night, even if you feel strange, you will just pass by and not stop for him.

Fu Wei's wrists show signs of struggle. The exposed skin of the murderer's wrists and face may be 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 store was opened and closed, and the abandoned elementary school. It means that he has lived at least locally for some time. There is no accomplice, because if two people, with the carefulness and boldness of the murderer, can take a more perfect crime, without having to go to the elementary school to change their blood coats, and leave traces.

He was very cruel to the corpse, almost out of control, and cut more than forty knives, saw the bones, and not for the purpose of concealing the identity and key characteristics of the corpse. Calm and angry, restrained and crazy, such contradictory manifestations must inevitably result from extreme mental distortion after long-term depression. His life was unsatisfactory. It was his instinct to kill people in such a rude, simple way. Such people will not, in reality, engage in jobs that require complex intelligence and interpersonal skills. In his mental state, he couldn't do it.

He hurried away after changing clothes at the elementary school. Did not stay, because with his care, if staying, blood stains will be found and cleaned up. But I just asked your people to check the surveillance within one hour after the incident. There was no suspect from the direction of the primary school, carrying a bag, wet hair, medium body, and hurrying on the road. So he lived within a few streets. Now you can ask questions. "

A criminal police officer said: "Professor Bo, I think the person you described is a bit contradictory. He has a thorough plan and is a master of crime, like a cultural, but rude, and also engaged in low-level work ...

Bo Jinyan smiled: "Yes, contradictions. The contradictions that cannot be reconciled are not the root of crime?"

This sentence caused the police to meditate. Another criminal policeman asked, "Why are you sure he was wearing a thick coat at the time? If he wanted to hide a knife, he could carry a bag, and didn't he just change the clothes?"

"In the bag? When the target comes over, unzip the zipper, remove the knife, and then chop the person? And risk the backpack strap as the victim's counterattack tool? No, how could our killer be so stupid? "

That said, the criminal police officer blushed, Bo Jinyan's eyes were shining, and Jian Yao beside him gave a cough, his eyes lightened and he calmed down, and said to the criminal policeman, "I'm telling the truth, not mocking you."

Interpol: "..."

Jian Yao: "..."

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

Everyone was surprised, even Jian Yao looked up. Woman? She never thought about this possibility.

Bo Jinyan stared at Fang Qing with a smile: "Oh, you asked a good question. 'He' is a man or a woman? The current case does not show any gender orientation. So I think he is A man of medium size, or a woman of sufficient strength. "

——

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

"Boss." Someone asked, "Are we going to find the suspect according to the portrait made by this professor?"

Fang Qing smoked a cigarette and said, "There are never too many roads up the mountain. It took us a week to solve the case, and it has now been 24 hours. We urged the city's authentication department to identify the murder weapon and the traces of the scene as soon as possible. Here we are. We can continue to search for the whereabouts of the weapon, check and monitor, and we cannot relax. Then, as Professor Bo said, go through all the investigated subjects again. "

"Boss, we have never completely relied on criminal psychology to solve the case, what if ... as he said, we can't find the suspect?"

Fang Qing smiled and said, "Can't find it? Then when he put a fart at us."

——

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

"Don't mess around." Jian Yao resisted. "I didn't wash my hands. I went to the scene just now."

But Bo Jinyan did not let go, and whispered in her ear: "Shhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh, if you do n’t hear it."

Jian Yao froze.

"Fu Wei lives in the Yao family inn, and his whereabouts are clearly grasped by the murderer. So maybe the murderer is also in this inn."

Jian Yao had a black line: "Well, don't you tell me that you're coming back to live with me ?!"

Bo Jinyan let go of her and lay down lazily by the bed: "Should I avoid the suspect?"

Jian Yao: "..."

Not this logic.

Well, she's calm, isn't she just a suspect in a murder case? She walked over and kicked his leg lightly: "Hey, go wash your hands and change your shoes and change your clothes, then lie down."

Bo Jinyan stood up obediently, walked to the porch, hung up his suit, bent over and put on slippers, and finally went to the pool to wash his face and hands.

Just like at home.

The sky is about to light up, close the curtains, lock the door, and leave only a soft old-fashioned table lamp on the bedside, which is also a safe and intimate small space. Bo Jinyan entered her tonight more enthusiastically than usual. Then she lowered her head and kissed her face and body inch by inch when her hands were against his chest, unable to rely on him. In fact, Jian Yao never told Bo Jinyan that such a move always moved her deeply and was irrelevant to sex. Because she could always feel his sincere, undisguised treasure.

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

After the incident, Bo Jinyan routinely asked the parties to feel: "Are you satisfied? Have you surpassed the previous one?"

Jian Yao looked at him in the misty light, and those eyes looked like a gentle star: "Jin Yan, I think this is your most manly time."

Bo Jinyan thought for a moment, then smiled: "Are you bragging about me or scolding me?"

Jian Yao froze and reacted. Did she mean to praise him? This guy has a strong EQ.

The two buried their heads and slept until the afternoon, there is no need to worry about the case, there will be an echo when there is progress. In the evening, the two strolled around the ancient city, ate some local specialties, and returned to the inn.

At the beginning of the lantern, the two stood quietly in the corridor on the second floor. Here you can see the ancient city wall in the distance and the lights on the river. The scenery is very quiet and warm. This is exactly what Jane Yao expects from this trip-it would be more perfect if there was no brutal murder.

"It seems to be the yard where the innkeeper lives." Jian Yao pointed out outside the courtyard. In fact, the two yards are connected. The smaller one is also tree-lined. There are a dozen courtyards, two-story buildings, and a dozen houses are lit.

"I heard that everyone lives there, the boss, the lady, the aunt, the cousin ..." Jian Yao sighed. "It's good to live in such an old house. The family is not separated. The independent yard, gray Tiles, white walls, green trees, ancient wells ... The slow pace is probably the quiet years. "

Bo Jinyan looked at her: "I know you like this kind of house, we will ..." Suddenly, Jian Yao was a little hesitant.

Because in the opposite yard, those rooms that were originally lit, as if they had been agreed, suddenly all went out. Around me, there was instant darkness. Only the shadow of the lone tree in the courtyard was still shaking gently in the moonlight.

Bo Jinyan frowned.

Jian Yao asked, "What's wrong?"

He said, "Nothing."
