Chapter 81 Couple Butcher: Suspect Arrested

"How do you know?" Fang Rui asked.

"My sister is now a lecturer in the Department of Psychology at Jiangzhou University. The head of the department told my sister that the school was short of a teacher to teach psychological therapy, so my sister took a part-time job. She had to work hard to make money to support me."

Mu Mian explained: "Some time ago, my sister took me to that school to play, and I secretly visited their laboratory. Their laboratory is so simple, they are so poor."

After lunch, Fang Rui and Mu Mian drove to Jiangzhou University again.

With the help of Shen Xinyin, they soon found out the whereabouts of the two devices. In the past two years, the department replaced a batch of psychological experimental equipment, and the two old equipment were sold as scrap.

Fang Rui asked the lab manager about the conductive paste again, "Since you have changed the equipment, why is your lab still using the previous conductive paste?"

"Well... this one is easier to use. The quality of domestic conductive paste is very poor, and its ability to reduce resistance is very weak, which can easily invalidate experimental data."

Looking at the manager's embarrassed face, Fang Rui felt that there was something fishy going on. Could it be that they were taking kickbacks from medical companies, so they kept buying expensive imported products?

"Who is in charge of purchasing equipment for your laboratory? We want to ask him something."

"The person in charge of purchasing is Director Zhou."

"Is his last name Zhou?" Fang Rui suddenly remembered the suspect Zhou Junwei from the previous investigation, and he asked, "Does this Director Zhou have a son named Zhou Junwei?"

"Yes. His son is also a lecturer in our school. If it weren't for Mr. Zhou's relationship, how could his son teach in our school." The administrator showed a contemptuous expression. Although he himself was also a related customer, he just couldn't stand Director Zhou's useless son.

"Please take us to see Director Zhou. I want to ask him something."

Director Zhou is in his fifties. He wears glasses and looks gentle, but when he sees Fang Rui and the others, he looks a little impatient. "If you have anything to say, just ask me now. I'm very busy!"

"You bought two NeurOne EEG devices ten years ago. Where did those two devices go?" "

They were sold. The two devices have been scrapped, so we sold them as scrap." Director Zhou replied impatiently.

"Which scrapyard did you sell it to?"

"How can I remember? Even if I tell you, you may not be able to find that scrapyard."

"How do you know we can't find it? Please tell us which scrapyard you sold it to. The owner will definitely remember it after purchasing such large equipment."

Director Zhou had lost his patience. He said to the manager, "Can you please stop bothering me with such trivial matters? You deal with them. I'm leaving."

"Director Zhou, I think it's better for you to tell me the truth. Otherwise, if we continue to investigate, we may find more things. For example, the fact that you took kickbacks." Fang Rui stopped him.

Director Zhou's face turned pale instantly. He asked the administrator to leave first, and then said to Fang Rui: "I sold those two devices. My son helped me sell them for tens of thousands of yuan. As for who the buyer was, I don't know."

"Did Zhou Junwei help you sell them?"

"Yes. Do you know my son?"

"Did he offer to help you sell them?"

"Yes, he said his classmate's school wanted to buy them. So I asked him to take the equipment away."

"Okay. Thank you for your cooperation." Fang Rui felt that Zhou Junwei was most likely the murderer. But strangely, he had an alibi.

Just after leaving the psychology department's office, Fang Rui saw Zhou Junwei staring at him and Mu Mian on the stairs not far away.

Noticing Fang Rui was looking at him, Zhou Junwei smiled at them, then went upstairs and left.

Zhou Junwei's smile made Fang Rui feel very uncomfortable. It seemed to be a mockery, and it seemed to be a provocation. His eyes seemed to say: You can't catch me at all.

Fang Rui investigated Zhou Junwei's information again. He was a native of Jiangzhou. When he was in high school, he sexually harassed a male classmate in the class. After being persuaded by the school to drop out, he was sent to Linzhou to study in high school, and later also in Linzhou to study in college.

He originally studied medicine in college, but changed his major to computer science in the second semester

of his freshman year. Fang Rui sent the experienced Lao Zhang to watch him for 20 hours. Although there is no evidence to prove that he is the murderer, keeping a close eye on him can prevent him from committing crimes again.

After returning to the bureau, Fang Rui received a text message from Captain Li:

"Fang Rui, save me! Why is this old guy Sun Guangtian so difficult to deal with? It's been three days. I haven't been home for three days. My wife suspects that I'm having an affair. Find an excuse to get me out of the task force."

Fang Rui poured a glass of water, but before he drank it, Xiao Zhang ran over and said, "Boss, Captain Sun and his team have caught the murderer!"

"Who is the suspect?" Fang Rui took a sip of water and asked calmly, "Is there any evidence?" "

The suspect is a sanitation worker in his fifties. Captain Sun checked a lot of surveillance videos and finally found the vehicle that seemed to be transporting the body of the deceased, thus locking in the suspect."

Fang Rui quickly learned from Song Haiyang about their investigation. It was similar to what Xiao Zhang described.

Team Sun discovered through surveillance that the sanitation workers at the gate of Jiangzhou University have a fixed cleaning time: once a day, between 8:00 and 10:00 p.m.

There is surveillance at the gate of Jiangzhou University, and there is also surveillance at the intersection 2,000 meters away from the gate of Jiangzhou University, but the area between the two surveillances is a blind spot, and the entrance to the forest is just in this blind spot.

On the evening of the 28th, an electric three-wheeled garbage truck appeared in the intersection surveillance at 6:11 p.m., but it was not until 8:13 p.m. that the truck appeared at the school gate. Then the sanitation worker got off the car to clean.

Captain Sun keenly discovered that in the surveillance at the intersection, there were no dead leaves and lavender fruits stuck to the wheels of the car, but in the surveillance at the school gate, these things were stuck to the wheels of the car - this proved that the car had been to the Koelreuteria forest during the time it disappeared.

The front of the garbage truck was completely closed, and it was impossible to tell whether there was anything hidden inside.

Captain Sun locked on the suspect through the car.

Fang Rui felt that Captain Sun's analysis made sense, but how could a sanitation worker think of such a complicated way to kill people?

"Haiyang, can I go with you to interrogate the suspect?" Fang Rui asked.

"This... I can't make the decision. Captain Sun needs to agree."

Fang Rui came to the task force's office with a bag of milk tea and midnight snacks.

The members of the task force had dark circles under their eyes and their hair was messy. They probably hadn't rested for many days. Sun Guangtian's dark circles were even more serious. Fang Rui suspected that he hadn't slept for the past few days.

When Captain Li saw Fang Rui coming, he felt like he had seen a savior. He silently accused Sun Guangtian of destroying them with his eyes.

Captain Li felt that Fang Rui was smart. He had quarreled with Sun Guangtian early and escaped from his clutches. Unlike him, he had been firmly grasped by the other party and allowed the other party to flatten and twist him.

Fang Rui distributed the food he bought to everyone. Everyone put down their work and the atmosphere became relaxed.

Sun Guangtian glanced at Fang Rui coldly. This kid is quite a good person.

Fang Rui handed Sun Guangtian a cup of milk tea, "Captain Sun, you should also pay more attention to your health. It's not good to stay up late like this often."

"I don't drink this stuff! Are you implying that I'm older?"

"Young people can't stand this either."

Several young people in the office nodded frantically. Captain Li was even more tearful. Fang Rui was really his good brother. In order to save him, he dared to confront Sun Guangtian.

Sun Guangtian took out half a pack of cigarettes from his pocket. He took out a cigarette and handed one to Fang Rui, "Have one to refresh yourself."

"Sorry, I don't smoke."

"This is a good habit. You should smoke less." Sun Guangtian put the cigarette back in his pocket, "Tell me, what do you want to talk to me about?"

"Captain Sun, can I interrogate the suspect with you?"

Sun Guangtian smiled at Fang Rui, "You kid can't investigate any further, so you come to me for inspiration?"

"I suspect that the suspect is not the real murderer." Fang Rui said.

Sun Guangtian blew out a smoke ring, "Okay, come with me to interrogate him."
