part-time profiler

Once there is a clue, things will move rapidly.

While Zhang Ke was searching for keywords, the field investigation team brought back news that Qin Chaoyang's key had been lost after a psychological counseling session.

The police quickly dispatched and brought Qin Chaoyang's psychological counselor back to the police station.

He is a graduate student in the Department of Psychology, named Qian Wei.

"Qian Wei, male, Han nationality, from Hubei Province, 30 years old," Zheng Lin posted his personal information on the clue board, and said in a deep voice, "Graduated from Ningbei University in 200X with a master's degree in psychology, and was admitted as a psychological counselor After obtaining the qualification certificate, he will operate his own psychological clinic in the southwestern district of our city."

"Qin Chaoyang suffered from bipolar disorder and bipolar disorder. He once had psychological counseling at Qian Wei's office. Later, at Qian Wei's suggestion, he left Ningbei and lived in other places for a long time." Zheng Lin stood in front of the clue board and looked into the big office. police officers.

"The psychological counselor matched the age and height." Yan Yan said in a low voice.

Yan Su stood beside him, shook his head, and said in a low voice, "It's not him."

Yan Yan took a deep breath.

The interrogator Xiao Liu walked out of the interrogation room and waved at Yan Yan: "Boss, I asked, Qian Wei didn't know about Qin Chaoyang's loss of keys at all, but Qin Zhaoyang did provide psychological counseling with him for a long time."

"Qin Chaoyang is Qian Wei's first long-term patient since he opened the psychological clinic." Xiao Liu said: "Qian Wei attaches great importance to the development of his condition."

"A graduate student who just graduated, the first patient." Yan Su muttered to himself: "If Qian Wei attached great importance to Qin Chaoyang's case, he would definitely discuss it with others or ask for advice on treatment methods. The person he is most likely to ask for advice is... ..."

Yan Su suddenly raised his head: "Who is Qian Wei's master tutor at school?"

Xiao Liu was stunned for a moment, glanced at Yan Yan, and rushed out of the big office: "I'll ask now!"

The truth seemed not far away, and the police officers were very excited.

Xiao Liu ran back quickly, but his expression was not excited, but dignified: "Boss, his mentor...the mentor is..."

"Zhang Zhenhai." Yan Su said suddenly.

Xiao Liu was stunned for a long time, and under the eyes of everyone who couldn't believe it, he nodded heavily.

Zheng Lin stepped forward and said, "Professor Zhang often goes in and out of the Municipal Bureau to provide psychological counseling for the public security personnel."

Shen Jia opened her mouth in shock: "Professor of the Department of Professional Psychology, married, no children, 1.8 meters tall, seems to be 50 years old this year."

Xiao Liu swallowed saliva and moistened his throat: "According to Qian Wei's description, Professor Zhang is very concerned about Qin Chaoyang's state. Zhang Zhenhai once suggested that Qin Chaoyang leave Ningbei and live in other places. Years ago, Professor Zhang gave Qin Chaoyang a psychological counseling alone. After that, Qin Zhaoyang's key was lost."

Zhang Ke ran over with a bitter face: "Boss, I have finished searching, and there is no one in our police that matches all the entries."

"Wait a minute," Yan Yan clenched his back molars, clenched his hands hanging by his sides into fists, his eyes were bright, and he said word by word, "Zhang Zhenhai, professor of psychology at Ningbei University."

Zhang Ke's eyes widened, and before he could say the damn thing, he heard Yan Yan order: "Immediately!"

"Why did Liu Bin go to Ningbei University to search, Shen Jia and Zheng Lin searched Zhang Zhenhai's house, and Gu Lei contacted the traffic control to block the entrances and exits of stations, airports, train stations, and expressways!" Yan Yan ordered: "Take action! The field team is out car!"

After a lightning search, the suspect Zhang Zhenhai did not come to school this morning. His wife said that her husband had not returned home for several months.

In the end, the police stopped Professor Zhang who was driving out of the city by himself at the intersection of the expressway, and brought him back to the Municipal Bureau in accordance with the regulations.

The result of Zhang Ke also came out, and Zhang Zhenhai completely matched the search keywords.

"Recently I'm working on a psychological topic of reproductive worship, and I'm divorced from his wife. Because of his testicular defect, he has been unable to have children with his wife. For this reason, he has been to the men's specialist hospital several times. His self-esteem is very strong. Except for his wife, No one knows about this. Colleague Mao Xuejun often takes care of Mao Xinyuan on behalf of the Mao family." Zhang Ke explained methodically.

"What did the police who caught him say?" Yan Su asked, "Has Mao Xinyuan been found?"

The scene fell into silence again, and the sudden question diluted the excitement and joy of catching the suspect.

"No." Zheng Lin slammed his fist into the desk: "No!"

Mao Xinyuan was not with Zhang Zhenhai, in other words, Zhang Zhenhai hid Mao Xinyuan.

"The fastest way at present is to find out the whereabouts of Mao Xinyuan through interrogation." Shen Jia looked at Yan Yan: "Boss."

The later one minute is, the more dangerous the little girl is.

Without further ado, after the police escorted Zhang Zhenhai to the Municipal Bureau, they passed the handover immediately, and the suspect Zhang Zhenhai was brought into the interrogation room by Shen Jia.

Shen Jia led Zhang Zhenhai through the corridor, Zhang Zhenhai kept his head down, he seemed shameless, his bald scalp was shiny, and his handcuffed hands were shaking violently.

When passing by Yan Su, he raised his head suddenly like some kind of telepathy, his eyes radiated a wolf-like light, staring at the expressionless Yan Su.

Yan Su showed no fear, and looked back at him calmly.Shen Jia threw Zhang Zhenhai into the interrogation room: "Cooperate, Professor."

"You have no evidence," Zhang Zhenhai was furious, and shouted loudly, "The police can't just arrest people!"

"You can tell Team Yan about this." Shen Jia slammed the iron door of the interrogation room from the outside.

Two hours later, Yan Yan still hadn't come out of the interrogation room, so Xiao Liu guessed, "It must have hit an iron plate."

Before he finished speaking, Yan Yan suddenly opened the iron door of the interrogation room, and walked out with an open face. Shen Jia, Zheng Lin and Xiao Liu Qi all surrounded him: "How do you say, is there any result?"

"The dead duck has a stubborn mouth. There is no physical forensic evidence to throw him in the face. I don't think he intends to speak." Yan Yan twisted his sore neck and asked, "Is the unidentified DNA in the staff dormitory consistent with the suspect's DNA?"

Shen Jia pouted: "There is no news from Liu Bin, and there is no result yet."

"We can wait for the result here with peace of mind, can Mao Xinyuan wait?" Zheng Lin was anxious like ants on a hot pot.

Yan Yan lowered his eyes and pondered, Yan Su, who had been silent all along, suddenly said, "Can I try?"

Everyone turned their heads and turned their eyes to him.

Xiao Liu has a spirit of humor, and commented with a smile: "Hey, iron plate against dead ducks."

Yan Yan ignored the joke, squinted his eyes and looked at Yan Su, as if considering the feasibility of having Yan Su interrogate Zhang Zhenhai.

After a while, the 1.9-meter criminal police detachment captain stepped aside and said with a half-smile, "Please."

Yan Su walked to the door of the interrogation room, turned around and said, "No one else should go in except me and Zhang Zhenhai."

Yan Yan narrowed his long eyes, and Zheng Lin stopped him: "No, this is against the rules."

Yan Yan raised his hand and stopped Zheng Lin who was coming forward to stop him. His eyes were always on Yan Su, and he asked in a low voice: "Well, I'll go in. Me, you and Zhang Zhenhai, and the others are waiting outside. Boss Yan, Can you see it?"

Yan Su's eyes dodged a little, and after a long time, he nodded subtly.

The two went in together.

Zhang Zhenhai was wearing handcuffs on both hands and feet, sitting on the iron chair opposite the iron table, looking at Yan Su and Yan Yan with his eyes.

When he saw Yan Su, he was visibly shaken, and the panic expression disappeared for a moment, then he looked back and looked straight ahead.

Zhang Zhenhai clasped his hands on the table with a straight face.

Yan Yan pulled out the chair and signaled Yan Su to sit on the side of the interrogator. After Yan Su sat down, he slowly stuffed his tall body between the narrow chair and the iron table, spread out the black leather interrogation record book, and held the index finger of his right hand. Twist the gel pen quickly with your thumb. "The results of the DNA test and fingerprint comparison have come out," Yan Su said, "The DNA and fingerprints extracted from the crime scene all show that they match you."

"Hehe." Zhang Zhenhai smiled calmly.

"I know you won't tell us Mao Xinyuan's whereabouts." Yan Su said calmly.

Yan Yan frowned, turned his head to look at Yan Su, the incandescent light shone on the young man's side cheeks, and his skin exuded a jade-like moist light.

Yan Su is always calm, Yan Yan knows that he should not be distracted during the work process, but at this moment, a certain thought can't be restrained in his mind, is this person always so clean-eyed?

Yan Sucai doesn't care whether you are a professor, the captain of the criminal police detachment or any other high-ranking person, he seems to be unable to let anyone in his eyes, his beautiful face maintains a noble posture, calm and unwavering, and his eyes are clean.

It seems that showing the slightest change of mood for mortals has tarnished his identity.

What identity?

Yan Yan lowered his eyelids, staring at the rapidly spinning gel pen in his hand.

"Professor," Yan Su took out the phone from his pocket, "We don't want to waste time."

Zhang Zhenhai looked at him strangely, probably not knowing what Yan Su was doing with his phone, and Yan Yan also looked at him curiously.

"Listen to a song." Yan Su said with a relaxed tone.

Yan Yan: "..."

Zhang Zhenhai: "..."

"Boss Yan, when is this?" Yan Yan wondered.

Yan Su turned on the player by himself, Yan Yan noticed out of the corner of his eye that he had chosen a local song, the title of which was a long string of English letters and numbers.

Then Yan Su put the phone out of Zhang Zhenhai's reach, stood up and took half a step back, staring at him expressionlessly.

Said it was a song, to Yan Yan's ears, it sounded more like an inexplicable howling of wolves and ghosts. Yan Yan suspected that he had heard it wrong, so he couldn't help but pierced his ears.

Immediately, something strange happened.

To Yan Yan and Yan Su, the innocuous noise pierced Zhang Zhenhai's ears like the shriek of an evil ghost, like the god of death wielding a huge and terrifying scythe, full of rotten blood, and strangled straight caught his throat.

In an instant, Zhang Zhenhai seemed to be choked by an invisible evil spirit, his face turned from red to purple, his eyes were wide open, his eyeballs almost popped out of their sockets, and he scratched with all his strength on the iron table with his hands. Across the iron table, there was a creepy and sharp sound.

Yan Yan stood up suddenly and shouted angrily: "Yan Su!"

Yan Su's face was also not very good-looking. He leaned his back against the wall, ignoring the furious Yan Yan at all, and fixed his eyes on Zhang Zhenhai who was struggling in pain on the verge of death. His voice sounded like a bell, hitting everyone's heart. He asked loudly: "Where is Mao Xinyuan!?"

Zhang Zhenhai couldn't breathe, stared at Yan Su's ordinary mobile phone, his face was full of despair, the veins on his forehead were bulging, and his face was distorted: "My child, of course, wants to accompany me, go to hell..."

Yan Yan gasped, and reached for Yan Su's cell phone, Yan Su pushed him away abruptly, Yan Yan staggered back two steps.

"Let me ask you," Yan Su said sternly, "Where is Mao Xinyuan?"

Zhang Zhenhai finally had no strength to resist. He bumped his head against the table, as if he was suffering from a thousand catties of pain. He wished he could die. He didn't even look like a professor he was half familiar with.

The middle-aged man explained in embarrassment: "In, in the east of the city, unfinished buildings..."

Yan Su quickly grabbed the phone, turned off the player, and turned to Yan Yan, who was still in a daze, and said, "Tell your people, don't let him die, start now, and save Mao Xinyuan!"
