Detective: I can see the criminal record

"This evidence will be very helpful for us to find other victims," ​​Cen Lian thought of the young girl who dared not tell them directly about the crime scene. "We can expand the scope of the investigation."

Lan Shengdong's previous visits to several nearby villages were not very effective. He could also see that some people should know something but were unwilling to tell them. Now that he has obtained the evidence, he needs to spend more time persuading these victims. Report the crime.

"I took a look, and the locations in these videos and photos were mainly in a room on the third floor." Ququhan looked around, "I haven't been inside, maybe I can find something."

Wu Qiushan heard this and walked over silently carrying the survey box.

"Wait a minute, the board is still with me." Tang Hua hugged the transparent acrylic board and chased after him.

Cen Lian can clearly feel Wu Qiushan's eagerness to solve this case. It is not that the case itself is difficult to solve, but that this kind of case that already knows who the murderer is, but cannot be solved due to the lack of some evidence is really disturbing. irritable.

Even a usually calm person like Wu Qiushan couldn't help but speed up the case handling when faced with this situation.

"I'm going to help communicate with the victims." Ququhan looked at it and found that his job was done, so he took the initiative to ask for help. "There are more female victims this time. The female police officers and internal staff of the Heyuan Police Station are probably not enough. ”

Cen Lian nodded. There is no need for network security to participate here for the time being.

"Everything will be fine if we can find the murder weapon. If we want to directly convict him of death with the evidence we have now, we will probably have to deal with the prosecution for a long time." Wang Yuanteng is obviously very experienced in this. "The biggest problem with the current evidence chain is the motive for committing the crime. And the method of committing the crime, if Chen Yong himself does not confess and we cannot provide clear evidence to prove that Chen Yong committed murder, it will be difficult to convict him of intentional homicide. "

For a person to be sentenced to death in court, it is not just a simple word from the public security organ. What is required is a complete chain of evidence and the approval of the prosecutor.

"I think Lan University can help us solve this problem soon." Cen Lian recalled the location described by the girl just now. It was obvious that she had seen the crime scene. "There is a witness who may have seen Chen Yong kill Chen Yong." Chen Xiaoxiao’s whole process.”

Wang Yuanteng looked around and confirmed that only the two of them were left in the room before he said, "I guess we can't be counted on for this case. All kinds of technologies are available. If Chen Yong was really involved in this case more than four years ago, I found a stone on the side of the road as the murder weapon, but I definitely can’t find it now.”

This kind of thing is only suitable for talking in private, but Cen Lian actually agrees with his statement.

The police are not omnipotent, and technical conditions are also limited. Not all cases can be easily solved using technical means. This is the case in front of you.

"Fortunately, there are witnesses." Wang Yuanteng felt a lot more relaxed after knowing that someone might have seen the crime scene. "Otherwise, we would have had to grind Chen Yong's confession."

Compared to interrogating a stone in a latrine, Wang Yuanteng still hopes that there will be witnesses who can directly prove his guilt.

"Forget it, let me see if I can find any clues in these videos." Cen Lian did not dwell on this issue anymore. Anyway, the victims who appeared in the videos and photos have been compiled into a list and handed over to Lan Shengdong. In his hands, whether he can find witnesses depends on Captain Lan's ability.

Cen Lian found some unexpected clues in a large number of videos shot by Chen Yong.

In one of the videos of a girl being brutally assaulted, he saw a crack in the door that had been pushed open a little. There was a figure behind the crack, holding up a mobile phone to take pictures quietly.

Based on the clothes that could be seen vaguely in the gap, Cen Lian was basically sure that the person holding the phone and secretly filming should be Chen Xiaoxiao.

"Brother Wang, come and take a look!" Cen Lian immediately enlarged the screenshot of the video, "The one secretly filmed through the crack of the door looks like Chen Xiaoxiao."

Upon hearing this, Wang Yuanteng immediately got closer and observed carefully, "This clothes seems to be what she was wearing when she was killed. It matches the remaining clothes we found on her body."

Cen Lian found the time when this video was taken and made a simple calculation in his mind.

The criminal record on Chen Yong's head shows the specific time when he killed Chen Xiaoxiao, just four days after this video was shot.

According to Chen Yong's criminal record, he violated the woman named Chen Mei four days before he killed Chen Xiaoxiao, which was the day the video was shot.

Therefore, the girl who was violated in the video was Chen Mei, and Chen Xiaoxiao took this opportunity to obtain evidence that Chen Yong violated Chen Mei.

From this point of view, Chen Xiaoxiao probably found the opportunity to escape from home four days after shooting the video. As a result, Chen Yong discovered that she was taking the evidence, and he killed her before she escaped from Xianghe Village.

This is the most reasonable explanation that Cen Lian can think of so far.

"If Chen Xiaoxiao really filmed evidence that Chen Yong violated other victims, then the motive for the murder would be very clear," Wang Yuanteng stood up straight, "Chen Yong's purpose of killing her was to silence her."

Just the number of minor victims confirmed from the videos stored on his computer is enough to give him an unlimited start. Once Chen Xiaoxiao calls the police, the police will definitely find his computer and the files stored in it like they do now. Things on the computer, so Chen Yong must not give Chen Xiaoxiao any chance to call the police.

"I don't know if the mobile phone Chen Xiaoxiao was using can still be found," Cen Lian thought, "but since Chen Yong killed Chen Xiaoxiao, there is no way he could keep that mobile phone."

"Now we have to see if Chen Xiaoxiao can think of any way to back up the videos she took." Wang Yuanteng looked at the notebook that Qu Han took in Cen Lian's hand, "It seems that Xiao Qu left early, and she can't get off work for the time being. ”

Ququhan, who had just left not long ago, was called back by Cen Lian's phone call.

"Social platform?" Ququhan immediately shook his head after hearing what the two said, "This kind of video cannot be uploaded. Even if it is sent privately to other people using chat software, it may be blocked. If she thought of saving this thing, The most likely possibility is to compress it and put it on your own cloud disk.”

Chen Xiaoxiao only has a junior high school education, and more complex computer operations are not practical for her, so Ququhan said the simplest way, "Or she secretly sends the video to someone else via Bluetooth and asks that person to help She saved it, but Chen Yong couldn’t give her a chance to touch the computer, even if she wanted to put it in the USB disk.”

"If I were her, I would ask Chen Mei to back up this video for me." Cen Lian put himself into Chen Xiaoxiao's situation at that time.

But Chen Mei was less than fourteen years old at the time, and she didn't know if she had the ability to help Chen Xiaoxiao preserve the evidence.
