Chapter 6:

Fang Qing was worried.
This case can be said to have made great progress, but it can also be said to have not.
Although the killer was cautious, the forensic officer extracted a vague fingerprint with blood from the door handle of that elementary school, and the blood belonged to the victim Fu Wei. With this fingerprint, it is enough to convict the murderer.
But they couldn't find the killer.
Compared with the police fingerprint database, it could not be found. After all, in our country, the coverage of fingerprint database is still limited.
The murderer's criminal motive and its connection with Fu Wei have not been found at all.
To be honest, Fang Qing had a kind of intuition before, this case is likely to become a pending case. What does it mean to have fingerprints? There are more outstanding cases of fingerprints and DNA in the files of the Ministry of Public Security.
But with Bo Jinyan's profile portrait of criminal psychology, the situation seems a little different. Fang Qing decided to use dead horses as living horse doctors. Try it first!
According to statistics, after Fu Wei came to the ancient city, he directly contacted a total of 128 people. About half of them had proof of absence on the night of the incident. According to the other conditions in the profile, half of the apparent non-conformities were eliminated, and there were still more than 30 people. Including: the owner of the small restaurant, buddies, several guests in the bar, taxi driver, inn waiter, several other guests ...
Fang Qing asked his men to call the police again for questioning. In order to avoid grass and snakes, he did not say explicitly, took the opportunity to take fingerprints, and then compared them one by one.
From this day's sunrise comparison to the evening, two-thirds have been carried out, none of them match.
In the evening, Fang Qing brought a group of criminal police to the meeting. Everyone swallowed the clouds and misted, obviously exhausted and flushed with red eyes, but they all had a strange kind of excitement.
"How is the fingerprint comparison going?" Fang Qing asked.
An investigator shook his head: "It's almost over. There is no match."
"Is there anything in Bo Jinyan's side?" Fang Qing asked again.
Everyone was silent, and one investigator replied: "Jian Yao called before and asked for the information of the owner of the Yao family inn."
Fang Qing: "Yao Family Inn?"
The investigator nodded: "Except for Yao Yuange, the boss is full of women. His wife, auntie, cousin, and two women who manage the restaurant."
Fang Qing heard the words lost in thought.
An old criminal policeman sneered and said, "I have managed that one before. There are actually some rumors about this Yao family ..."
Several criminal policemen smiled scornfully and narrowly. Obviously, everyone has heard that rumor.
Fang Qing raised his head: "The dead Fu Wei lives in the inn. At present, the people he has contacted, we only counted the front desk, the waiter, the guests in the surrounding rooms ... Will the Yao family have contact with him?"
This question was not answered by investigators.
Fang Qing also said, "Fu Wei is very ordinary at first glance. But the same problem reflected by everyone around is lust. The backyard of the Yao family is full of women, and it is connected with the inn's garden. If Fu Wei Ever had contact with them or one of them, would this have anything to do with his death? "
Fang Qing also remembered that the back door of that elementary school was actually not far from the Yaojia Inn.
Case investigation seems to have a new direction. But everything is just guessing. After thinking about it, Fang Qing decided to go to Bo Jinyan again.
At the moment, Bo Jinyan was receiving a call.
It was his subordinate, An Yan, who is also a member of the Criminal Psychology Laboratory. An Yan, like Bo Jinyan, is also a guy who lacks common sense and is an IT otaku. At the moment An Yan asked gently on the phone: "Boss, when are you coming back?"
Bo Jinyan replied indifferently: "A few more days."
An Yan: "SX has a new serial robbery and homicide case. The criminals have not left any valuable clues, and dozens of criminal police have been dumped. Should our team answer them?"
Bo Jinyan: "Oh."
The two were silent, and another person spoke on the other side of the phone. It was Fu Jinyu, Bo Jinyan's friend. He is a well-known doctor, and Jian Yao has been flirting recently. He has also come to Bo Jinyan's small group to practice medicine. Just listening to Fu Ziyu laughed and laughed, "An Yan, you are not really knowledgeable. Jin Yan is going to chase Jianyao. He dares to come back now, isn't he afraid that Jianyao will let him off?"
An Yan: "Oh ..."
Bo Jinyan hung up the phone directly.
Jian Yao was looking at the information at the table, looked up to see his face, and asked softly, "What's the matter?"
Bo Jinyan shook his head very calmly: "It's all right, two naive and boring single men."
Jian Yao's eyes smiled.
Bring him a cup of tea, accompany him, and look at the data of that family dozens of meters away. At this moment, the sky was still bright, the twilight was floating, and the yard was quiet and quiet.
Yao Yuange, his information has been read in the police station, including the notes Fang Qing talked to him that night, will not repeat them.
Yao Yuange's wife is Ming Lan, 45 years old, and is also his wife. From the photos, it is a dignified and cool-looking wife. Ming Lan was originally a rich local girl, but her family was worse than Yao Yuange's. After marrying him, he did not work outside. Now he is working on a bar by the lake for Yao Yuange. Both had no children.
Ming Yan, Ming Lan's younger sister, 29 years old, also lives in the Yao family. After graduating from high school, he worked in the Yaojia factory and has not recently worked. It seems that Yao Yuange also raised the wife and sister. Ming Ming is not married, but has a son, who is 5 years old. The biological father is unknown. Judging from the photos, Ming Yun's appearance is not as good as her sister's, she is honest and honest, but she is also innocent.
Zhang Jufang, Yao Yuange's cousin, is very thin, looks beautiful, and has white skin and fine eyes, 30 years old. unmarried. He used to be an actor of the Repertory Theatre and was good at singing Peking Opera. Now living in the Yao family, it is said that he manages the factory account for his cousin and spends most of his time at home.
Zhao Xia and Chen Mei are the foremen of the restaurant that Yao Yuange picked up by hand, and their positions are not high. Zhao Xia was born with a round face, and is 35 years old this year. Chen Mei is dry and thin, 32 years old, and looks pretty. Neither of them had a high education background, and both were from rural areas. It is said that neither of them got married, because the Yao family's courtyard was near the restaurant, so they also lived.
The rest are the five maids in the yard. Both aunts in their 40s and 50s sometimes go to the front yard to help with cleaning.
...
Footsteps came, Bo Jinyan and Jian Yao both looked up. Fang Qing walked down the corridor with a deep complexion.
"Professor Bo, talk for a second?"
As soon as the three entered the room, Fang Qing opened the door and said, "According to the portrait you said, we have already checked nearly a hundred people, and no fingerprints are right."
Bo Jinyan replied: "That shows that the scope of your investigation is not complete."
Fang Qing glanced at the information on the table: "Do you suspect that the Yao family has anything to do with this case?"
Bo Jinyan only replied: "They should also be under investigation."
