Detective: I can see the criminal record

Gao Tong's case has come to an end, and the new case has returned to the state that Cen Lian is most familiar with.

I know the answer, but the process of solving the problem is a bit rough.

It's time to use his reverse reasoning ability again!

Cen Lian got used to the computer at his new work station that looked to be no more than five years old, and chose to check Yang Xu's household registration information.

Before retiring, this murderer worked as an ideological and political teacher in the junior high school of the No. 5 Middle School in Gaoyang City, Kaizhou Province, a neighboring province in Yunling Province. In the photo, he looks human-like, and someone who doesn’t know can say that he has a good temperament.

But after knowing the crime he committed, he could only be described in two words in Cen Lian's eyes - Lao Deng.

However, judging from his past experience, this Yang Xu really doesn't look like someone who can do such a thing.

He even obtained the title of special teacher before retiring. It can be said that he is also a famous figure in the world.

Cen Lian retrieved cases named after several other victims and found that the four victims were both male and female, and they were not in the same province. In addition to the age of the victims, they were all violated but had internal organs. Aside from the fact that no bodily fluids were left behind, there aren't many similarities between the time and place of the cases.

Even the cause of death of the deceased is different.

For example, Chu Yulin, the deceased in Case 1022, according to the analysis of the forensic autopsy report, he was directly beaten to death with irregular hard objects such as stones after being controlled by the murderer.

It can be seen from the choice of murder weapons that Yang Xu prefers to kill people directly by using handy tools that can be found at the scene.

Of the previous deaths, one was strangled to death by a half-section of wires thrown into the wasteland, and the other was directly stabbed to death by a half-section of steel bars near the construction site.

The only time he missed, the victim was hit in the forehead by a broken pottery vat from the waste recycling bin, causing brain damage. Although the person was still alive, he suffered the sequelae of lifelong disability and has not been able to regain normal language and thinking functions. , resulting in the police being unable to get any clues from him.

After looking at several cases, Cen Lian also realized that it would be very difficult to have conclusive evidence to arrest Yang Xu in this case.

At least for now, their investigation direction is unlikely to yield results.

The murderer Yang Xu was not a native of Kang'an City. The previous cases, including this one, were committed across provinces.

Cen Lian first sorted out these cases and put them aside. Tang Hua has already obtained the surveillance cameras brought back by other teams this time and is reviewing them in detail.

In the middle of the night, it was too late to go to the factory dormitory to investigate.

Wang Yuanteng is also watching the surveillance. If he can find a positive face from the infinite surveillance, it will be of great help in solving the case.

Qi Yan, who had been silent on the road, suddenly raised his head.

"I saw him going outside the park." Qi Yan marked a new point on the map pasted on the whiteboard in the office area, "This direction is towards the city!"

At this time, there are seven or eight locations marked sporadically on the map, all of which are places where the man in black has appeared.

"This path is not like that of workers who have lived in the factory dormitories in the park for a long time." Cen Lian took the opportunity to guide their thoughts, "You see, the location where he first appeared in the surveillance was already in the center of the park, and he appeared several times after that. It was near the crime scene. After leaving the crime scene, he kept moving toward the exit of the park and then disappeared between two surveillance cameras."

"You want to say that he changed clothes before entering the park and after leaving the park." Qi Yan frowned, "But there are no suspicious characters in other surveillance near the park."

Cen Lian didn't quite understand the concept of this suspicious person.

"When you conducted previous investigations, what was the age range of the murderer?" he asked hesitantly.

"18 to 55." Wang Yuanteng said without thinking.

Their movements finally caught the attention of the other two groups.

Liang Xuan walked to the whiteboard and frowned to observe carefully.

"This age range is indeed narrow. It is relaxed to 14 years old downwards and 70 years old upwards." She quickly made a judgment and "rescreened within this age range."

Qi Yan returned to the computer suspiciously and reopened the surveillance video.

Liang Xuan turned to look at Cen Lian.

"I think you seem to have other ideas." Her tone was quite firm.

Cen Lian suddenly felt like he had been seen through. Although Liang Xuan was a few years older than him, her sharp eyes resembled his high school teacher.

You can tell where he hides his phone at a glance.

Cen Lian said calmly: "I just found a few similar cases. I'm not sure if they were done by the same person."

Liang Xuan stared more closely.

Cen Lian remained calm-faced. After all, no matter how sharp his eyes were, his high school teacher could never find where he hid his cell phone.

Liang Xuan looked at several cases he printed out, and her face gradually became serious.

"The criteria for your screening are assault and homicide cases that do not leave any bodily fluids and have the tendency to kill intentionally." Liang Xuan looked at it carefully and said: "Although there are no conditions for merging the cases, you can open your mind in this direction. If these few If the case is committed by the same murderer, then he must not be from Kang'an City."

As a result, the previous investigation direction was somewhat biased.

"I'm going to find Captain Tan." Liang Xuan felt that under the current situation, it was not enough to continue investigating the factory workers.

Tang Hua approached Cen Lian with confusion after Liang Xuan left.

"How did you find these cases?" If he remembered correctly, it had only been a few hours.

Of course, Cen Lian cannot say that he searched directly based on the list of victims.

"I found it based on my intuition when I was looking for murder cases related to assault." Cen Lian's face was full of casualness.

"I believe you." Of course Tang Hua didn't believe it, but he couldn't think of any other reason, so he had to go back and watch the surveillance.

After working overtime all night, there were no results. Cen Lian returned to the dormitory arranged for them by the branch in the early morning to sleep. As soon as his head touched the bed, he immediately lost consciousness.

Early the next morning, he was woken up by Tang Hua's phone call.

"Get up, we should go out and continue the investigation." Tang Hua's voice on the other end of the phone was a little unclear, and he was obviously not too sleepy.

Cen Lian rubbed his eyes and got up, his mind full of how to make all the evidence point to the murderer Yang Xu.

It's too difficult. None of the existing evidence can implicate him.

After meeting Tang Hua and Wang Yuanteng, Cen Lian was somewhat surprised to find that Qi Yan was not there.

"Don't look, it's just the three of us," Wang Yuanteng yawned, "Qi Yan and the others went to check the surveillance of the hotel near the park."

It seems that thanks to his efforts last night, Team Tan has successfully found a new direction.

"Then let's set off," Cen Lian yawned and finally woke up a little under the cold wind at the end of October. "Maybe we can try our luck and find some new clues."
