Chapter 17:

"Then these missing girls ..." the policewoman asked. "Where is it now?"
Fang Qing and Jian Yao both looked at Bo Jinyan. He was silent for a while and replied: "He collected the same type of alternatives, not different types. The time interval of each case is quite stable, and is more than one year ... and the frequency interval has accelerated in recent years. Generally speaking, new toys are needed only if old toys are broken. "
Fang Qing drank the beer in the glass and said coldly, "I must catch this pervert and bring him to justice!"

However, the identity of the victim was confirmed, and the method of evading the police's sight was also determined. Even the suspect seemed to be in sight. However, it is difficult to find further evidence.
Looking through the files of that year, the telephone was connected to the criminal police at the time, and no clues were found in the ancient city. Fang Qing was sitting in the office, and when nothing was happening, Bo Jinyan came over and stood beside him with a smile.
Fang Qing didn't look up: "Is there something wrong?"
Bo Jinyan said indifferently: "It seems that you forgot what I said. When traditional criminal investigation is powerless, criminal psychology comes forward."
Fang Qinghuo looked up at him: "Do you have a way?"
Bo Jinyan said "heh": "When did I ... be as lost as you?"
Fang Qing: "..."
In the large conference room, there were Fang Qing, Jian Yao, and several backbone criminals. Bo Jinyan was standing in front of the whiteboard in a suit, with one hand in his trouser pocket, and the other hand holding a pen. Although he has contributed several paragraphs of reasoning in the process, this is the first time he has officially given a briefing to Gucheng Interpol.
"There is evidence that Yao Yuange is related to two of the disappearances. However, there is no direct evidence that he is a criminal. So we cannot rule out the possibility of other suspects. Let us call him Suspect A.
A's strongest desire is to collect young, beautiful and vulnerable women. This reflects his strong possessiveness, which must occupy a dominant position in the relationship between men and women. As a teenager, he lacked confidence in the relationship between men and women. This must have something to do with his childhood environment. He comes from a discordant family, or has suffered different problems. Based on the earliest case in 2008, A should now be at least 30 years old.
According to the meticulous means of abduction, it can be inferred that A and his accomplice B must have observed and selected the victim for some time in advance.
The first step, where are they looking for goals?
The victims are tourists, and they often go to tourist attractions, ancient city walls, bars, restaurants and inns. In this place, A or B must have enough time to observe the victims and even talk to them. And A or B often appears here and is not noticeable. Therefore, this place will not be a tourist attraction that is only visited once, it will not be the ancient city streets that are casually strolling, and the inns where the victims live are different. So the most likely is a bar, cafe or restaurant. A or B is a regular here, and maybe even the staff here.
The second step is how do they commit the crime?
These girls are introverted and will not go to remote and distant places. The ancient city is full of people, the possibility of violent abduction is very small, and it is difficult to leave no trace. Therefore, the location of the abduction should be on a relatively remote and unattended road. And the abduction is B, not A. B is female and owns a car. In any case, they can't ensure that the victims will be willing to get in the car of a man who just met a few days ago, and they are introverted girls. But the words of women are much easier.
The relationship between A and B must be very close. They are husband and wife, lovers or relatives. A has a separate residence for the victims. The victim disappeared one or two days before the date of the ferry or ticket. Because the longer the time interval, the easier it is for police to find loopholes. And in terms of the economic conditions of the victims, they live in very cheap inns with loose management. Even if they disappear without saying a greeting, they will not attract attention.
Since the victim's body has not been found so far, it was either stored in A's home or discarded in a fixed place. That place was inaccessible, or it was also his private place. "
After Bo Jinyan spoke, everyone was quiet.
After a while, a criminal policeman exhaled and said, "Oh my God, Yao Yuange has hit all the rules." He turned over the information in his hand: "He is 48 years old, and the five wives in the family can help. There is a bar under Ming Lan's name, and it is still in a busy area. Ming Lan drives a black Audi. "
"Yes." Bo Jinyan smiled slightly. "Although it is not possible to exclude others from committing crimes, Yao Yuange and Ming Lan can be regarded as the number one suspect."
"Then where do we start now?" An Interpol asked. "There is not enough evidence to apply for a search warrant against the Yao family."
"Check Lan!" Fang Qing said coldly, "Check her car."
"Yes," said Bo Jinyan, "the average tourist stay in the ancient city will not exceed 4 or 5 days. Start with the cases of the last two victims, Zhu Fanglin and Ning Qianrui, because the closer the time, the more surveillance cameras According to the date of the ferry ticket and the ticket, push forward 3-6 days to find out the whereabouts of Lan's car, especially the surveillance on the relatively remote street that has not left the city. There is no real perfect crime , There must be a trace somewhere. Go find her and our victim, the scene of intersection. "
"This is a lot of work," muttered a criminal policeman. "Let's move now." Fang Qing nodded.
But Bo Jinyan said at this time: "What do you spend on those things? This kind of thing, leave it to my people to do it. Jian Yao, call An Yan. There is no case in the group recently, he is also wasteful to leave, It's time to work. "

The call between Jian Yao and An Yan is very brief. Because An Yan on the other side of the phone was so loud that she didn't wake up yet.
But Jian Yao is used to it. IT otaku, rightly so.
"An Yan, the case information has been passed to you."
"it is good."
"Jin Yan wants you to find out ..." Jian Yao demanded.
"okay."
"Is it difficult?" Jian Yao thoughtfully.
"No." A light reply.
"Oh ... when will it give us results?" She asked again.
"I don't know," he answered, "I'll give it to you when you're done."
"Okay, it's hard. Then there's nothing else, shall I hang up?"
"Sister, bring me some peach cakes from the old city, sweeter," he said.
"Oh, yes."
Hanging up the phone, Jian Yao looked at Bo Jinyan sitting opposite. They are in the office right now. He is holding the file and is still looking through it.
Jian Yao lay on the table and looked at him.
In this way, once again, he twitched his words, and in a few words, he found the shortcut to the truth behind the mist.
"My habit of investigating investigations takes shortcuts. You have to get used to it and keep up."
When he first met, he was content with what he said to her. Until now, I still remember it.
"When traditional criminal investigation is powerless, criminal psychology comes forward."
His light words, but they could make her bloody, and make her tears.
Under the light, his black hair was like flowing clouds and his shirt was white. The handsome and fair face was as before. He was quiet most of the time, and only spoke with her when she was with her. But when investigating a case or looking at information, she talks to her rarely.
But she felt that he was the best Jin Yan in the world.
"Why keep looking at me?" He didn't look up and his voice was low.
"Nothing," she answered.
He put down the dossier, stared at her for a moment, and suddenly he came over and kissed her on the lips.
"Don't look at me with that emotional look when I'm examining the case. I can feel that I'm restless physically and mentally and my judgment is affected."
After a while, Jian Yao reacted to the meaning of "restlessness", and her face was a little hot. And he simply drank a large mouthful of herbal tea, smiled slightly thoughtfully, walked to the window, turned his back to her, and continued to look at the file.
In the evening, An Yan passed the results.
Fang Qing and the policemen filled their chests with an ecstatic, cheery, cold mood as soon as they saw it. I just want to laugh and scold.
"Apply for a search warrant now!" Fang Qing shouted. "Go to Yao's house."
In several sets of pictures from An Yan, Ming Lan's license plate was clearly captured. On a sparsely pedestrian street, she showed her face from the window, smiling and speaking to the fourth victim Zhu Fanglin on the roadside.
And she was driving on the street, and the camera at the intersection was the picture of the fifth victim Ning Qianrui sitting in the co-driver.
