Chapter 67:

The evening wind came slowly in through the window. The detective's voice was buzzing in his ear. Jian Yao looked at Bo Jinyan across the round table. The criminal police probably discussed it, and nobody looked at him. An Yan blushed and lowered her head, Fang Qing looked through all the indifference.
Bo Jinyan's face slowly turned red.
He raised his head, in the direction of her and Fang Qing. Place your hand on the table and slowly tighten it. Then he reached for his sunglasses on his face.
He didn't say a word.
She didn't speak, she just sat in silence.
There was a time when she and Bo Jinyan were relatively speechless?
"... Otherwise, let's ask Jian Yao and Fang Qing first to express their opinions." Shao Yong's voice intervened at this moment.
Jian Yao answered "OK", looking down at her notebook, but her heart still seemed to be lying on a cold wasteland.
"We have the following preliminary conclusions. First, the murderer was a premeditated murder. Nie Shijun's habit of running at night, not many people know. The murderer followed her and chose a very suitable time for murder, and The most suitable place for murder on her running route. After the complete murder, he did not meet the witnesses. He also prepared a complete set of tools such as ropes, paints, gloves, etc. in advance. Therefore, he was neither a rush nor an impulsive killer. It's not that he randomly hits a night runner and kills him. Nie Shijun is his selected target ... "
Her voice gradually calmed down. She thought, it was strange that she hadn't imagined reuniting with Bo Jinyan. She thought she must be very sad and excited, and she might rush to hug him and cry, blame him, beat him, and forgive him. But when it happened, everything turned out to be so quiet.
Quiet as if it was just a turn in life and met him once again.
"Second, the killer often lives near the rental house where Nie Shijun lives, or near the park, and is likely to live nearby. Geographical Criminal Psychology tells us that no matter what the killer is, Because of the killing, he and the victim must have met in a certain place before. Nie Shijun's life is very monotonous. After investigation, the place where she often moves is home, company, park, and will go to the mall on weekends. Here Of the four locations, only the rented house and the park are nearby. The murderer is the easiest to stay and observe the victim, and he finally chose to kill in the park, indicating that this is a psychologically familiar place. If it is only on the way to work A quick glance at the mall. The murderer lives far from here. One is that it is difficult to keep track of the victim, and the other is committing a crime in an unfamiliar park. For a novice, it will be very difficult to adapt psychologically.
Third, the murderer was well thought out and well-planned, and behaved neatly. This also reflects his personality characteristics. "Butterfly" must have a special psychological meaning to him. But I also noticed that the butterflies he painted were softer. It is unknown what this means.
Fourth, he lacks criminal experience and is a novice. So why choose to kill at this time, and kill in a special way. It must be related to a specific stimulus he has recently received. While Nie Shijun was chosen as a victim by him, there must be factors related to this particular stimulus. Therefore, we need to continue to investigate Nie Shijun in depth. If we know more about the victims, we will know more about our perpetrators.
Our conclusion is that much for the time being. As for whether the killer is a mentally ill, serial killer. As only one case has occurred, it remains to be seen. "
After she finished speaking, all the police officers nodded frequently.
Jian Yao couldn't help but look at Jin Yan again, his face was still so calm. I wonder if it was her illusion, and felt that the lines of his lips were softer.
Jian Yao suddenly pressed her temples, trying to calm herself down.
It's psychological. She could feel two scorching eyes, just like she had stopped at her yesterday.
It was his eyes that were already dim and stared at her.
The one who ran away from home was blindly looking.
Jian Yao took the cup and swallowed, moisturizing her almost dry throat.
Shao Yong said, "Thank you Jian Yao and Fang Qing, then Jin Yan, what's your opinion?"
All eyes turned towards him again.
Bo Jinyan was silent for a moment.
At this moment, Jian Yao suddenly remembered the past. And she clearly felt that Bo Jinyan must also remember. How many times had he stood with her, he broke through her confusion. Use his wisdom to lead her to grow.
Sometimes it is a compliment: "The flower of our criminal psychology is finally on the road." Sometimes it is mocked mercilessly: "Awesome, you have come to three conclusions, two of which are guesses."
...
"Jane Yao's reasoning today is very good, much better than I thought ... much better." He said slowly, "I will add three more conclusions."
Jian Yao's throat suddenly became a little blocked. The conference room was so quiet. Everyone looked straight at Bo Jinyan and the legendary blind detective, and what more valuable conclusions could be drawn.
Bo Jinyan smiled suddenly. He touched the tea cup next to him, took a sip of light, and put it down. An idea rushed into Jian Yao's mind: The tea here was not good enough, and he couldn't drink it. Just don't let your mouth be too dry.
Then he spoke quietly. The deep and pleasant voice, with a sense of alienation and pride in calmness, was no different from the past.
"I. The murderer has good economic conditions and a clean and decent shape. The paint, ropes and other tools he uses to commit the crime are the best. This does not mean that he is a professional in this field, but at least it shows that he is financially There is no pressure. And, the habit of choosing is good.
A person who has cleaned the crime scene so cleanly and methodically is not likely to be a sloppy, unkempt person. That behavior is contradictory.
2. More precisely, the area where the killer is often active is near the rental house, not the park. "
Jian Yao felt a little shocked.
The feeling of familiarity for many days came to mind. The man always looked farther, more accurately, and was right next to her.
Bo Jinyan paused and said, "It is also the same as" Geographical Criminal Psychology "that tells us that there are four types of killers: hunters, poachers, opportunists, and underdogs. The hunters are familiar with Look for victims near the area. Poachers look for victims in a specific place. With the careful planning style of the killer, it is impossible to think of it. After this case, the park will strengthen the entire security surveillance. Some people dare to run in the park. If he is a serial killer, he will no longer be able to commit crimes here and must abandon the park. Therefore, the place of "park" is not a place where he is psychologically dependent and a fixed hunting ground. In other words, he It's not a hunt for prey in the park. Here, he can give up at any time. "
Jian Yao was shocked. Bo Jinyan's point of view at this moment is already a little deeper, and some police officers have shown a dazed look. But she understood instantly.
