After receiving the clues, everyone immediately screened the factories that excluded the eligibility.

Sure enough, a steel mill that had closed down half a year ago due to environmental concerns was discovered, and the police quickly arrived here to search the surrounding reeds.

The police officers soon found some residual blood stains in the grass here, and Lao Ji preliminarily judged that the time of death of the deceased was very close to the time of death based on the dryness of these blood stains.

The group then searched along the trail marks and eventually found many intricate footprints under a tree. Everyone looked at the traces of struggle on the ground, and it was hard to imagine how helpless and desperate the girl was when she encountered the murderer in this deserted place.

After searching the nearby factory, Cuong accidentally found the deceased's mobile phone and underwear inside. In this way, the murderer should have abducted the deceased here, and then dragged the deceased into the factory to commit the crime.

But Lao Ji was very puzzled, this place was at least more than 100 meters away from the gate of the factory, why did the murderer take the trouble to drag Ma Shasha into the factory again?

Later, Xiao He got the news again, he asked the police to investigate the yellow shipment record, and unexpectedly found that Wang Wei's mother only bought the dress back on Saturday night. This also shows that Wang Wei wore this yellow coat to see Ma Shasha on the day of the crime.

got a clue, Lao Ji and the others took advantage of Wang Wei's school to come to her house, and her parents seemed to be very unwelcoming of their arrival. Lao Ji directly told her daughter's relationship with this case, and in order to clear the child of suspicion, her mother told Wang Wei to say whatever she knew, so that the police would not come to her again.

Wang Wei said that at about 5 o'clock in the afternoon on Sunday, she suddenly received a call from Sasha, and she felt as if Sasha was crying. But no matter how much she asked, Sasha wouldn't tell what had happened, just asked him to find her and remember to bring her a coat.

She didn't think much of it when she hung up the phone, but when she got there according to the location, she found that it was an abandoned factory. When she came in, she saw Sasha curled up on the ground in the corner, and she also felt that Sasha was a little abnormal, but she just didn't say what happened.

Later, she said she was going to do something important, and the two separated. As soon as Wang Wei's words fell, her father issued an eviction order.

After coming to the car, Lao Ji still felt that there was something wrong with Wang Wei's confession, if Ma Shasha called Wang Wei after being violated, then she must have had a lot of scratches on her body at that time, so how could Wang Wei lightly separate from her good friend.

Xiao He suspected that Wang Wei should have some things that she hadn't told the police, but why did she hide it?

When I returned to the technical department of the police station, I sent Ma Shasha's mobile phone repair data, but I found that Ma Shasha had been chatting frequently with a boy named Qian Xiaoshuai in the past two months. And the last thing they chatted about was to go to the factory where the crime occurred to take pictures.

But the strange thing is that judging from the photos in the album, this Qian Xiaoshuai seems to have a closer relationship with Wang Wei. Coupled with Wang Wei's previous baby's lying behavior, Xiao He wondered if it would be Qian Xiaoshuai who committed the crime against Ma Shasha with the help of Wang Wei.

After hearing this, Lao Ji thought that this speculation was very bold, but he could not rule out this possibility, so he immediately asked him to investigate in this direction.

Since the other party is still a student, Ah Qiang suggested that Xiao He should not startle the snake first, he wanted to get Qian Xiaoshuai's saliva for comparison first, and then judge his suspicion after the results came out.

After Qian Xiaoshuai came in, Xiao He first asked very politely, the relationship between him and the two girls, Qian Xiaoshuai looked relieved after hearing it.

He said that Wang Wei was the person he liked, and because Ma Shasha and Wang Wei were good friends, the three of them often played together. However, he thinks that Ma Shasha's conditions are not good and he has low self-esteem, so he and Ma Shasha rarely communicate. Xiao He found that Qian Xiaoshuai's answer was very contradictory to the content of Ma Shasha's mobile phone, but Xiao He did not rush to demolish him, but just asked him to drink some water and relax.

Before this, Ah Qiang had already done some investigation on him, and because Qian Xiaoshuai's family was very advantageous, he was sent abroad by his parents to study very early. It wasn't until half a year ago that he transferred to this school because of his father's work problems, and he is also very good-looking, so he is very popular with girls at school.

Judging from Qian Xiaoshuai's answer just now, he seems to be full of superiority over his own conditions. After sending Qian Xiaoshuai away, Ah Qiang immediately took the cup he had just used for a laboratory test, and unexpectedly the results showed that the traces in the deceased's body were from Qian Xiaoshuai.

In this way, it is likely that he took the opportunity to commit a crime against the deceased while taking pictures. Now that the evidence is conclusive, the police immediately brought Qian Xiaoshuai back to the police station again.

But when Lao Ji questioned him with the inspection report, Qian Xiaoshuai thought that this didn't mean anything, and he insisted that Ma Shasha, who had a bad family background, liked him, so he took the initiative to seduce him when taking pictures. And he felt that between them was just a matter of your willingness, which was not a crime.

As for the murder, Qian Xiaoshuai resolutely denied it. Lao Ji was very annoyed when he came out of the interrogation room, he did not expect that this boy with a delicate appearance would not only be very dirty in his heart, but also slander the deceased in the face of ironclad evidence.

In order to get more evidence, Lao Ji and Sister Xi came to Qian Xiaoshuai's house to investigate, but after the two entered his room, the first thing they saw was a cabinet full of trophies and medals.

Lao Ji found Qian Xiaoshuai's camera when he inspected the house, but after opening the camera, he didn't find a memory card inside. The two of them did their own search of the house, and Lao Ji noticed that something was wrong with the cabinet where the trophies were placed.

Judging from the neat arrangement inside, this should be the place where Qian Xiaoshuai shows his trophies. But in such a place that is not satisfied with honor, why is there a toy car that is out of place.

Lao Ji took it down for his own inspection, but unexpectedly found the camera's memory card inside, so it seems that Qian Xiaoshuai regarded the content he shot as his own trophy, and all of them were placed together with the trophy.
