The three returned to the police station with no results.

As soon as Fang Jinan arrived at the police station, he went directly to the data room.

Su Ran knew that he had something on his mind, but Fang Jinan didn't want to say it, and she wouldn't ask.

It was He Yang who felt that Fang Jinan was very strange, so he asked Su Ran, "What's the matter with Fang Jinan?" ”

Su Ran sighed and shrugged his shoulders, with an expression that I didn't know about.

He Yang glanced at his mouth, "Let him go." ”

Fang Jinan is also He Yang's apprentice, he naturally knows Fang Jinan's temperament, don't look at his usual hippie smile, in fact, he is a very delicate person in his heart, and his head is very hard, if he thinks it is right, it is useless for others to persuade him, unless he tries it himself, he will know.

In the archives, Fang Jinan flipped through a case four years ago.

It is also a case of a mentally disabled person who was stabbed with an iron rod in the lower body, but the person who was stabbed was not as lucky as Chen Gang, she died.

And he knew her.

The deceased man's name was Kim so-lian, who was born with an intellectual disability and could not speak.

When she was a child, Fang Jinan lived in the same town as her.

Jin Xiulian usually doesn't like to stay at home honestly, she likes to run out and stumble blindly on the road, Fang Jinan avoids her every time she sees her.

But Jin Xiulian didn't know what it meant to be annoying, and every time she looked at Fang Jin'an, she smiled at him.

Fang Jin'an's house is an inconspicuous small county, there are all kinds of people, especially the gangsters are particularly rampant, once he came home from the Internet café, and was suddenly intercepted by three or five gangsters, asking him to take out all the money on his body.

Fang Jin'an's family background is not particularly good, he knows that it is not easy to make money, he is stubborn, and he is unwilling to give money to those gangsters.

As a result, those gangsters were annoyed and punched and kicked him, who knew that halfway to kill Cheng bit Jin, Jin Xiulian took a basin of water and poured it towards the group of gangsters.

Everyone here knew that she was crazy, and whoever provoked her would get dirty, and the thugs scattered when they saw her.

Who said she was stupid? Since that time, Fang Jinan feels that she is not stupid at all!

But the good times didn't last long, and Jin Xiulian died of illness.

This illness was silent, so it came, and it took her away.

A few days before she died, her family took her to the hospital for an examination and found that there were 30 centimeters of steel bars in her pelvis.

It turned out that Kim Xiulian was sick because of a deep infection, and there was tetanus, and it didn't last long before Kim Xiulian died.

She was 40 years old when she died.

Fang Jinan was not at home at the beginning, but only learned about it when he came back from other places.

At that time, the police tried to find out, but they could not find any clues, and the only witness was that Kim Xiulian herself was also dead.

Except for the two clues of steel and wooden sticks, there are no other clues left.

The case was put on hold.

After four years, he became a police officer, and now he has discovered a case with the same modus operandi, which is an eye-opener.

The length and diameter of the wooden stick on the data are exactly the same as the one inserted into Chen Gang.

It cannot be ruled out that the same person committed the crime.

Although the motive for the crime is unknown, this person's goal is very simple, specifically targeting people with intellectual disabilities.

Fang Jinan flipped out the map of Ningjiang District and specially checked the distance between his hometown Wenyuan Town and Zhaicui Village.

Not very far apart.

If this span is not far away, the probability of the same person committing a crime is relatively high. If the span is far, it is not excluded that the crime will be committed through the channeling route.

Fang Jinan was looking seriously, and suddenly there was two knocks on the door of the archive room.

Before Fang Jinan could ask who it was, the door opened half by itself with a "creak", revealing half of Su Ran's body.

Fang Jinan turned his head to look at her with a puzzled expression.

Su Ran pushed the door open entirely, clasped his hands to his chest and said, "Team He convened a meeting to discuss." ”

Fang Jinan closed the case file in his hand, "It's here." ”

With that, he followed Su Ran.

In general, in major criminal cases, there will be a lot of people in the meeting, because society puts pressure on the superiors, and the superiors exert pressure on the people under them. There was no fatal case like this, there was no serious impact on the social panic, and few people even knew about it, only a few people were sitting scattered in the conference room.

Fang Jinan handed the materials brought from the archives to He Yang.

He Yang looked at him, then took the information from his hand and looked at it.

Su Ran saw He Yang's brows slowly furrowed, and vaguely felt that the information that Fang Jinan showed to He Yang was related to Chen Gang's case, Su Ran was able to go over it, He Yang just finished reading it, and directly stuffed the information into Su Ran's hand.

Su Ran looked at this case, it turned out that such a technique had happened four years ago.

"Is it the same person who committed the crime?" Su Ran raised his head from the information and asked.

Fang Jinan pursed his lips, "It's possible, the place where this case happened is near my hometown, I just checked the map, and my hometown is not far from Zhaicui Village." ”

He Yang's expression was solemn, staring ahead in a daze, not knowing what he was thinking.

After a while, He Yang instructed Su Ran to print out a few copies of the materials and send them to the few people in the meeting to read.

"Okay." Su Ran immediately trotted towards the printer.

The information was distributed, and Fang Jinan and Su Ran sat down.

He Yang then spoke: "This is a case four years ago, the deceased Jin Xiulian's body was also inserted into a wooden stick of about the same size, because the time is too long, we have no way to know whether the wooden stick taken out of Chen Gang's body is the same as the wood or from the same place, but at least it can explain two issues, first, this murderer is only aimed at disabled people." Second, the information from four years ago was not as widespread as it is now, and few people knew about this case, if it was not the same person, then he should have known about it and imitated it. If it is an imitation of the crime, then this person may have stayed in Wenyuan Town for a period of time before, and then it is very likely that he moved to Zhaicui Village. ”

He Yang pasted the information on the blackboard and continued: "Now let's go to Zhaicui Village to investigate whether anyone has just moved to Zhaicui Village in the past four years. ”

As soon as the order was issued, no one dared to slack off.

They all stood up and walked towards the police car outside the door.

Su Ran and Fang Jinan had investigated in Zhaicui Village before, and they were also familiar with the environment over there, so they got out of the car, and the two of them took their own people to act separately.

He Yang walked around the village alone.

As I walked, I noticed that a family seemed to be isolated from the village.

The houses in Zhaicui Village are all lined up, one after the other, but this low house is alone opposite this row of village houses.

Could it be that they moved here later?
