Chapter 464 Clues

"Pan Zhaoqing went to the laboratory this morning," Deng Yaojun explained, scratching his head. "The school didn't let us in, so we had to stay downstairs."

After that, he pointed to the tall building in the distance.

"He is participating in a high-risk classified experiment. There is currently no evidence that can restrict his personal freedom. But we have been staying here and we haven't seen Pan Zhaoqing come out."

Meng Hua answered: "There are four South China Political and Legal Experimental Buildings, and he often goes to Building 2. According to the investigation, there are a large number of dangerous chemicals inside."

"Slow down, Pan Zhaoqing is a law student, right? How can he get involved with chemistry?"

Gao Jinyang was confused.

Jiang Yang answered for him: "Because his undergraduate major is investigative science, which involves some basic chemistry. Pan Zhaoqing only took the law major as a graduate student."

"In addition to chemistry, toxicology testing is also a key subject."

"If you focus on criminal science and technology, chemistry is one of the core courses."

Two of the four victims of the N2 poisoning case were also detectives.

"We'll talk about the subjects later. Come with me to arrest them."

As Jiang Yang walked towards the laboratory building, he contacted the headquarters and asked his superiors to issue a search warrant.

The crime radar flickered faintly, and when it approached the detection range of 740 meters, a small crimson dot suddenly appeared.

[Pan Zhaoqing, 26 years old, was involved in intentional poisoning and murder, stealing banned high-risk chemicals, instigating multiple crimes, and falsifying experimental data...]

The detailed crimes are listed one after another, clearly recording the past of this top student.

The first time he showed his criminal tendencies was when he was in junior high school, when he encouraged his father, Pan Kuang, to publish negative remarks on the Internet to expand his influence. After the success, it was suggested that Pan Kuang would sell the illegally obtained obscene videos in the form of CDs.

But his father had no other options, so he gave up at this time.

In college, Pan Zhaoqing guided Li Liang to exploit legal loopholes and make profits from them.

Including Liu Wude and the police's guerrilla-style extortion, it was also his work.

Looking closely at Pan Zhaoqing's methods, each item is related to what he has learned.

"Instigation" is derived from the combination of investigative psychology and intelligence science.

Jiang Yang's face darkened and he quickened his pace.

"Hey! What are you doing! The laboratory building does not allow idlers to enter... Officer Jiang?"

From a distance, the security guard of the building saw more than a dozen figures approaching menacingly, with their hands on the walkie-talkies around their waists. When they got closer, they saw that it was the famous Jiang Yang!

He suddenly became excited and laughed out loud.

"Is there anything I can do to help? Officers."

Jiang Yang produced a search warrant and asked Pan Zhaoqing which laboratory he was in.

"Oh, Teacher Pan is on the twelfth floor. But you need to swipe the key card to enter. I will take you there!"

The security guard was so excited that he walked quickly ahead without forgetting to report to the school leaders.

"You go up the stairs. Brother Liu and Brother Liang will lead people to guard the exits of the laboratory building. Don't let anyone escape."

Jiang Yang turned his head and whispered instructions.

Everyone received the task and split up.

When the security guard opened the glass door of the laboratory, Jiang Yang and Yu Jing rushed to the front.

"Police measures, please cooperate with the investigation, sit in your seats and don't move!"

There were about twenty students in the laboratory, staring blankly at the uninvited guest who suddenly came in.

Jiang Yang and Yu Jing exchanged glances. The former glanced at Pan Zhaoqing who was standing in the corner.

The latter worked with other police officers to calm the students who were at a loss and arranged for them to take statements one by one.

"Mr. Pan, after investigation by the police, it is now suspected that you are related to multiple criminal crimes and a campus poisoning case. Please come back with us to assist in the investigation."

Jiang Yang showed his ID again, took out the handcuffs and stepped forward.

"I recognize you, Jiang Yang, who was promoted to the Provincial Public Security Bureau from Rongcheng City."

Pan Zhaoqing was very calm, not at all panicked.

He even smiled at Jiang Yang.

"I really want to cooperate with the police to solve the case as soon as possible, but the project I am currently working on is a confidential task of the national discipline. Do you have tangible evidence to prove that the case is related to me? Otherwise, you cannot arrest him by force."

Pan Zhaoqing was confident and looked at Jiang Yang with sarcasm hidden in his eyes.

"There are a total of nineteen experimental groups at South China University of Political Science and Law that can apply for N-dimethylnitrosamine."

Jiang Yang said coldly: "It has been verified that only the laboratory you participated in consumed more N2 than the standard this month. Another point is that I received a report that your experimental data was distorted, and it has been further confirmed by the superior quality inspection department, chemistry teaching and research staff, etc. Forensic investigation.”

He finished speaking calmly, and saw a hint of confusion on Pan Zhaoqing's face.

"Are you scared?"

"You probably haven't contacted your undergraduate college teacher for a while, right?"

"Why?"

Jiang Yang pressed forward step by step, getting closer to him.

"Is it because your civil law course teacher joined other students to report your misconduct many times while you were studying at South China University of Political Science and Law? Mr. Pan, I advise you to give up your resistance and take the initiative to confess."

Pan Zhaoqing submitted a doctoral candidate application to the dean of Kyoto University School of Law at the beginning of the year.

However, it was rejected within two months.

The reason for the dean's reply was that the number of people was full.

Not long after, the list of proposed candidates under the dean's name was announced, and one of them was Zhang Junde.

As for Chen Yang, the civil law teacher who bravely reported the case, his nephew was one of the poisoned victims, Yang Yifan.

This part is an investigation of the social relations of the four victims that Mao Yi sent one after another.

"Your motive for committing the crime is clear, which is to take revenge on the teacher who once reported you and the classmate who competed with you for the postgraduate position. You have successfully instigated and instigated your father, Li Liang, and Liu Wude to commit crimes and escape legal sanctions by sticking to the red line, which made you more and more daring and designed poisoning and murder."

"You have studied investigation and law for so many years, and you really think you are good enough to take advantage of loopholes, right?"

Jiang Yang stood in front of Pan Zhaoqing and suddenly pulled him over and held him down.

The silver handcuffs "clicked" on the other's wrist, and the cold touch immediately stimulated Pan Zhaoqing to come back to his senses.

"You can't arrest me! I'm one of the researchers of a national secret project! You are not qualified to arrest me! Let me go! I didn't do anything! It's all your wishful thinking! The police don't have any substantial evidence at all!"

"Jiang, you just want to torture me into confessing!"

"Don't think I don't know your interrogation process, help! Help me! The police are beating me!"

Pan Zhaoqing yelled incoherently, struggled madly, and kept hitting Jiang Yang with his hands and feet.

"What other evidence do you want?"

"Surveillance from the school canteen? Or the forensic report on the body fluid test of the deceased?"

"You bought a dozen Cokes in the laboratory a week before the incident because you knew Yang Yifan and Zhang Junde loved to drink them, and deliberately induced them to drink the poisoned Coke you put in. Is that true?"

Jiang Yang raised his voice and punched him in the back of his waist, knocking him down, with one leg across Pan Zhaoqing's chest.

"I, I didn't! You're talking nonsense!"

"Bang!"
