part-time profiler

Professor Zhang, an old acquaintance, often comes to the Municipal Bureau for psychological investigation and counseling.

Yan Yan turned around and asked Shen Jia: "Professor Zhang came to give psychological counseling to the anti-drug police, is he still in the bureau?"

Shen Jia put her hips on her hips, shook her ball head, and replied: "Leaving early, I bumped into him when I was going out. I walked in a hurry and said something happened at school."

"Oh, yes." Yan Yan lowered his eyes, thoughtful.

There was unrest in the reception room.

The sudden ringing of the mobile phone pierced the quiet air. Mao Xuejun took out the mobile phone and saw the anonymous number. He jumped up excitedly and pointed at his mobile phone tremblingly: "Kidnapper, kidnapper!"

Zhang Kesa ran back to the office and returned to the communication tracking equipment. Mao Xuejun trotted over, and everyone squeezed into the narrow office.

"Hang up." Yan Yan ordered.

"What?" Mao Xuejun couldn't believe it, Shen Jia simply grabbed his phone and pressed to hang up.

"If the mouse is in a hurry to ask for money, it will definitely call a second time immediately." Shen Jia explained in a simple manner, and said simply: "Don't worry, listen to our boss!"

After the debugging of the communication tracking equipment was completed quickly, Zhang Ke raised his head and made an OK gesture.

When the anonymous number was dialed in again, Mao Xuejun's hands trembled, and he looked at the expressionless Yan Yan with asking and begging eyes.

Yan Yan folded his arms and nodded: "Pick it up, remember to prolong the call as long as possible."

Shen Jia held a small whiteboard and a black watercolor pen: "I'll write the answer here."

Mao Xuejun pressed the call button.

"Do you fucking want your daughter? Then hang up on me! I'm going to kill this son of a bitch!"

Mao Xuejun's hands trembled, the phone almost fell to the ground, he frantically held it steady, and looked at Shen Jia for help.

Shen Jia quickly wrote on the whiteboard: Busy.

As expected of a high-level intellectual, Mao Xuejun still has some IQ. He understood quickly, and immediately argued with the mouse: "Didn't I just have something to do? There are a lot of things in school recently, and the end of the term is coming. How can you judge the grades of the students?" Wait, wait, I will definitely save my daughter, and I am also collecting money, the key is 400 million in cash, and I won't be able to get it out for a while..."

Mao Xuejun still wanted to continue talking, but the mouse interrupted him impatiently: "Don't talk nonsense, you called the police, don't fucking think I don't know, just tell you that I know every move. 800 million, in cash, isn’t your wife rich enough to start a company, she has to get it all together the day after tomorrow, hand over the money to the person, don’t play tricks with me!”

Shen Jia took a pen and wrote on the whiteboard: Too late.

Mao Xuejun swallowed, and called to the mouse before he hung up: "Don't, brother, didn't you say 400 million last time, cash, who will get it in a while, you want 800 million, doubled, Even if my wife is running a company, she can’t produce so much cash in two days. Brother, can you accommodate me for a few more days? I’m not in a hurry to ask for money. Let’s talk about the police..."

Yan Yan shook his head.

Mao Xuejun turned back abruptly: "Besides, I sincerely want to save Yuanyuan. I'm just such a daughter. Aren't I afraid? The child's mother is also in a hurry. We are really nervous..."

The mouse scolded angrily: "I'm in a hurry, why aren't I in a hurry?! Damn it, I hate you all acting like dogs and doing dirty things behind your back, bah!" The mouse spat and hung up the phone.

The beep sounded.

Mao Xuejun was paralyzed and fell to the ground. Wang Hui covered her lips and asked nervously and painfully: "What should I do? What should I do? 800 million..."

He Wei leaned over, patted Mao Xuejun on the shoulder, and helped him up.

Yan Yan asked Zhang Ke: "How?"

Zhang Ke was discouraged, sat up straight and leaned back, shaking his head: "Mouse has a strong anti-reconnaissance awareness, and the call time is too short, so I haven't confirmed the exact location, but it must be in Ningbei City."

Wang Hui burst into tears. Mao Xuejun's cell phone rang again, and he received a multimedia message. He opened it and saw that his body that had just stood upright fell to the ground again.

Shen Jia took away his mobile phone, a photo, and a bloody little finger.

"Ah—" Wang Hui screamed, "Yuanyuan's——"

"Boss, what should we do now?" He Wei looked at Yan Yan.

Zheng Lin, who had been silent all this time, suddenly said, "It's a bit strange."

Yan Yan raised his head and looked at Zheng Lin, and they saw the same thoughts in each other's eyes.

"What's so strange?" Liu Bin wondered.

"It's just started, and the mouse needs 400 million. He didn't say the time and place of the transaction, and his tone was not as urgent as this time." Yan Yan explained: "But this time, the mouse was obviously angry. He was in a hurry and asked for three days to meet With 800 million in cash, the ransom has also doubled, this time, he really wants the money."

Shen Jia had a flash of inspiration: "Boss, are you saying that he didn't ask for money so urgently for the first time, or that asking for money was not the main purpose."

Yan Yan nodded, thought for a while and said, "Miaozi said that he knows every move of the police. We guess that he has an accomplice within the police. The original words of the mouse are that he looks like a dog on the surface, at least it shows that the accomplice's social status is not low."

"In the investigation of the disappearance scene, it was discovered that someone was supposed to pick up Mao Xinyuan on Friday night, and the adult who was going to pick up Mao Xinyuan was most likely the rat's accomplice."

"Then why didn't the mouse ask for money the first time, but the second time? The ransom was doubled." He Wei asked.

"Having an accomplice means an accomplice committing a crime. The criminals don't always have the same purpose. I guess the main purpose of the accomplice is not money, but another purpose, and the rat..." Yan Yan raised his eyebrows: "I really want money."

"So there is a conflict between the two." Zheng Lin took up his words: "The reason why the mouse dared to kidnap Mao Xinyuan on the second day of the arrest operation must be inseparable from the help of the accomplice."

Shen Jia nodded: "Understood."

"This person is among the police, and he may be by our side. At the same time, he is also a friend of Professor Mao or President Wang." Yan Yan knocked on Zhang Ke's computer desk: "Cross-compare our city's editorial and temporary public security personnel with Mao Xinyuan Parents' circle of friends."

Zhang Ke scratched the back of his head and supported the glasses frame: "Boss, this workload is a bit heavy."

Yan Yan shrugged and smiled: "It's time to show your real skills."

Zhang Ke replied with the same smile: "Yes, sir. The overtime salary for this month has been approved quickly."

Comrade Yan Yan said OK.

A group of people walked out of the technical investigation office, and Zheng Lin suddenly turned around and asked, "Is there still a shortage of money after graduating from Massachusetts?"

Zhang Ke thought for a while, and replied earnestly and sadly: "Studying has made the family poor, and the loan has not been repaid until now. The US book is 100 million a year. Listen to me, Brother Zheng, don't play it to your death in the future." Sending children to study in capitalist countries is a pit, a huge pit!"

"Oh," Zheng Lin showed an exaggerated expression and spread his hands, "Evil capitalism."

Zhang Ke kept smiling: "Socialism is good."

Yan Yan drove to Ningbei University without stopping.

Professor Zhang is teaching graduate students.

Ningbei University has an open style of study, and students from other majors can also attend the postgraduate classes.

Yan Yan entered the small teaching classroom. There were more than ten students in the classroom. Zhang Zhenhai stood on the podium with a projection screen hanging behind him. It was his teaching PPT, the classroom theme, Criminal Minds: Analysis of the Causes of Paedophilia.

Yan Yan was sitting behind the classroom. Professor Zhang saw him and nodded to him. Yan Yan nodded in return. The students occasionally turned their heads to look at the sudden tall man. Listening to the class, thinking that such a handsome person is not a student.

Professor Zhang's voice is very gentle, and he said: "We say that mental illness is usually related to childhood experiences, and pedophilia is no exception. It may be due to the disharmony in the family relationship in childhood, which leads to the combination of adults. Loss of interest, that's one. And second, there are social factors, like major emotional setbacks, that turn the focus on the children..."

Yan Yan waited until Professor Zhang dismissed get out of class.

Zhang Zhenhai didn't bring textbooks, just a USB flash drive. He pulled it out from the main computer and put it back in his pocket. Yan Yan got up, and the two of them walked out of the classroom together and walked along the lawn behind the school teaching building.

"Is there a big case?" Zhang Zhenhai asked softly, Yan Yan took a deep breath and nodded: "The suspect in the cross-border child trafficking case, Mouse, you know."

Zhang Zhenhai nodded, Yan Yan smiled wryly: "Run away again."

Zhang Zhenhai patted him on the shoulder to show comfort, Yan Yan asked him in a chatty tone, "Are you busy recently?"

"It's okay, as always, I take the subject to attend class, and occasionally go to the police station." Zhang Zhenhai suddenly asked: "I don't go to the Three Treasures Hall for nothing. Team Yan came to the school to find me in person. What's the matter?"

"Oh, that's it. I want to ask, do you know Mao Xinyuan?" Yan Yan observed his expression.

Zhang Zhenhai was taken aback for a moment. He probably didn't expect him to ask this suddenly. He nodded and said, "Yes, Lao Mao's daughter. What's the matter?"

Yan Yan hissed and sighed: "It's nothing. Have you seen her recently?"

"No, speaking of it, I haven't seen that girl for a long time, she's quite smart," Zhang Zhenhai sighed, "It's just that her parents have a bad relationship, and that girl has suffered a lot of grievances."

Yan Yan bowed his head and remained silent. After a while, he changed the subject and said half-jokingly and half-seriously: "You have studied psychology for so many years and taught criminal psychology courses. How many talents should we train? The Criminal Psychology Research Office has just been established, and Lao Zhao wonders if he can't recruit anyone."

Zhang Zhenhai laughed loudly, and clapped his hands and said: "Everything is difficult at the beginning. Criminal psychology research is still in the development stage in our country. The application is not deep enough, and there are not many studies. Your city bureau opened a criminal psychology laboratory and asked me to do it. What about training?"

Yan Yan echoed him with a smile: "The professor is great, Lao Zhao asks you to guide, it should be."

Zhang Zhenhai sighed: "Speaking of which, I have taught for so many years, and the most talented students I have met are not my own students."

"Oh?" Yan Yan became interested: "How do you say that?"

"I saw you at the study meeting last time." Zhang Zhenhai pointed at him and shook his finger, and said mysteriously: "You have been staring at the kid next to me, right?"

Yan Yan was startled, smiled, and did not deny it: "What does this have to do with what we just said?"

"As soon as that kid came, everyone stared at him. He is beautiful, and everyone likes it, regardless of gender." Zhang Zhenhai had an insight into people's hearts. He thought that Yan Yan kept staring at others because of Yan Su's good looks.

Yan Yan didn't explain the reason, but answered yes vaguely.

"It's just him. If he comes to the criminal psychology class, he will keep the full score of the exam." Zhang Zhenhai stopped and turned to face Yan Yan.

The two stood still under the shade of the tree, and the breeze was blowing.

Zhang Zhenhai thought for a moment, and suggested: "If you are short of someone, you can ask him, his name is Yan Su."
