Chapter 15： suddenly... uneasy

"First, the bloodstained graffiti of the on-site investigation are not disordered, but wild roses." Chen Yan shared his findings as soon as possible.

"In the two murders, the crime scene is almost the same. This is the murderer's message to the outside world."

"The cross symbolizes redemption, kneeling symbolizes repentance, and there is a saying in the flower language of wild roses that it is repentance!"

"...So, it is initially determined that this is a well-planned revenge murder case!"

Shock!

Everyone's eyes looking at Chen Yan are full of shock!

In such a strange murder case with no clue, Chen Yan actually sorted out the clues in such a short period of time, and preliminarily determined the murderer's motive!

You must know that it is very important to deduce the motive of the murderer based on the clues. This is the key information point to lock the target group of the murderer.

And Chen Yan, in one day, not only found the gloves used by the murderer, but also deduced the motive of the crime, which is simply incredible!

"Right now, the most crucial clue is the relationship between the two victims. Since it is a revenge murder case, the relationship between the two is very important... Team 1, contact the technical department to obtain all the social chat software records of Lin Chao and Wang Xuefeng."

"Team 2, make every effort to investigate the use of the drug succinylcholine in Liancheng... Focus on investigating whether the medical department of Lianhai University has access to use or extraction conditions."

"Team 3, check to see if there have been any recent criminal or civil cases involving Lianhai University students or teachers."

…

Twenty minutes later, a team completed the retrieval of the social chat software records of the two victims.

"Team Leader Chen, the two's social software is mainly WeChat and QQ, and neither of them found much abnormality."

Nothing too unusual?

Chen Yan frowned: "What do you mean there is nothing too abnormal?"

"That is, the two added friends once two years ago, but they deleted it after only a week."

Chen Yan's eyes lit up: "Quick, immediately arrange for someone to search Lin Chao and Wang Xuefeng's computers, especially Wang Xuefeng's computers, including personal computers and the computers he uses in school."

Wang Xuefeng is a graduate student majoring in computer science. Of course, he is the focus of Chen Yan's research in computer research.

The speed of the detective team is still very fast.

In just an hour, the two team members ran in sweating profusely.

"Team leader! Team leader!"

"Major clues!"

"It turns out that the two deceased people knew each other. Wang Xuefeng developed a simple chat software on the school's server called Soul Hotel. They are all members of this hotel!"

"Team leader, here is the list of members and chat records."

Chen Yan took the list and looked at it carefully.

"Team leader, the case you asked us to investigate about Lianhai University has also come out. There are a total of 12 cases involving Lianhai University in one year."

"Eight of them were teachers' family disputes, two were students suing teachers for sexual assault, and two were student suicides."

"Suicide?" Chen Yan raised his head: "What's the name of the deceased?"

"Yang Xiaoxiao and Xu Chang!"

As soon as the two names came out, Chen Yan looked at the sky outside the window.

"Captain, hurry up!"

"Send someone to Lianhai University to find Li Hai from the Department of Architecture and Sun Feng from the Department of Mathematics!"

"Others, arrest Yang Xiaoxiao and Xu Chang's father immediately!"

…

Although Zhang Yunhu doesn't quite understand what's going on, Chen Yan is now the leader of the task force, and executing orders is the first criterion.

Shut down the video that has been connected with the superior, and immediately organized the police to set off for Lianhai University.

However, Chen Yan and others were still a step too late.

Li Hai and Sun Feng disappeared.

Yang Xiaoxiao and Xu Chang's father were not at home either, so the arresting officers rushed to nothing.

"Team leader, what should I do now?" Liu Qingshan is no longer called Chen Yanxiaochen.

In the police force, the premise of talking about seniority is that you are better than others, but when your ability is not as good as others, you have to follow the rules.

Take Zhang Yunhu, for example, there are more than a dozen people in the detective team, including Liu Qingshan, who are older than him.

But which meeting is not respectful and honest, who dares to put on the pedigree of the predecessors?

This is the impact of competence and position.

And Chen Yan, now is the ability outstanding!

Chen Yan's face was ashen.

The murderer is more cunning than imagined...and more decisive.

Moreover, Chen Yan now realizes that the other party has no intention of escaping the punishment of the law at all.

He... No, everything they did was to delay time.

Delayed until all four were killed.

Actually, after reading the chat records of the Soul Hotel, Chen Yan wanted to help the two murderers, the fathers of the two suicide girls.

However, the duty of the police prevented Chen Yan from doing so.

Even if Lin Chao, Wang Xuefeng, Li Hai and Sun Feng deserve to die, they should be punished by the law.

No one has the right to take another person's life away.

"Room 301 in the third teaching building, and classroom 202 in the ninth teaching building, send someone immediately!"

Yang Xiaoxiao and Xu Chang are classmates and classmates of Lin Chao.

There are only four places where they take classes.

Apart from classrooms 204 and 306 in the twelfth teaching building where two murders just happened, there are only classrooms 301 in the third teaching building and 202 in the ninth teaching building.

Yang Xiaoxiao and Xu Chang have a good relationship, and they sit together every class.

One of the profile photos brought back by the three teams was taken during class by Yang Xiaoxiao and Xu Chang.

The orientation of the two is the direction that Lin Chao and Wang Xuefeng's human skins and corpses are facing!

This time, the two teams arrived at the two teaching buildings on time.

"You guys came much earlier than I thought." Yang Chenghan didn't hysteria, he didn't resist, and he didn't kidnap Li Hai.

He just scratched Li Hai's face with a knife the moment he turned around.

…

trial room.

Chen Yan sat opposite Yang Chenghan.

The other party insisted on seeing him.

"You are much younger than I thought." Yang Chenghan, sitting in the interrogation chair, did not have a trace of brutality as a murderer.

Instead, he is like an intellectual, elegant and easy-going.

In fact, Yang Chenghan is also an intellectual.

Lianhai University's top professor of computer science, Yang Xiaoxiao's father, is also Wang Xuefeng's mentor.

And Xu Chang's father, Xu Bin, was a colleague with Yang Chenghan, and he was the deputy dean of the Medical Department of Lianhai University. He extracted succinylcholine.

When the two murdered, they injected succinylcholine into the victim's body, so that the other party was unable to resist or cry out.

After that, the people were bled, the wild roses were drawn, and then they were pinned on the blackboard and peeled little by little.

After the victim fainted, he sprinkled the wound with strong alcohol to stimulate the victim to wake up, and continued until the victim's skin was completely peeled off without breathing.

This is why the scene smells of alcohol.

Watching that his skin was peeled off, UU reading www.uukanshu. com can imagine how much fear the victim endured.

"How did you find out?" Chen Yan sighed.

Yang Chenghan knew that Chen Yan was asking, how did he and Xu Bin find out the reason for his daughter's suicide

"Why didn't you delete the chat room?" Chen Yan knew that, as a professor in the School of Computer Science, if he deleted the chat software created by Wang Xuefeng in advance, he would not be able to find out.

It is impossible to solve the case so quickly.

"There is always something left. Death is too cheap for them."

"does it worth?"

A professor, a vice dean...

Yang Chenghan helped his glasses and leaned forward slightly: "Officer Chen, if you also had a daughter who had the same experience as mine, what would you do?"

Chen Yan was slightly startled.

For some reason, the shadow of Shen Yunyi appeared in Chen Yan's mind.

Chen Yan did not answer Yang Chenghan's words.

He is a little... afraid

Chen Yan would let the man know that death is actually the happiest thing in the world.

And, he swore, no one could catch him.

The interrogation went very smoothly, and the video cable was also broken by the two of them working together.

Yang Chenghan touched the honey on it, and the medical test rat brought from Xu Bin bit it off, creating the illusion of an unexpected malfunction.

The purpose is to delay the police's handling of the case.

In fact, the two of them had discussed it. If the police didn't solve the case, they would turn themselves in.

However, they didn't expect the police to arrive so quickly!

Now, although it is not complete, neither Li Hai nor Sun Feng were killed, but both of them have been disfigured, and after such a period of experience, I believe that these two will not have a good night's sleep in this life.

Revenge... done.
