On the night of Jin Yishuo's arrest, song Jingan, Cao Wei and Zhang Mingcheng interrogated him overnight. Even Yang detachment attached great importance to him and went to the monitoring room to watch them interrogate.

But no matter what they asked, Jin Yishuo kept silent. When it came to the critical moment, he laughed wildly.

After more than an hour's interrogation, they didn't ask anything. Zhang Mingcheng slapped down the table angrily: "Jin Yishuo, don't think that if you don't speak now, we can't convict you. From the mobile phone you found, you can see the emails you sent to us. And today, you pretend to be a delivery man and enter our song team's house with a knife, He tried to attack Fu qihan. At last, he was stopped by one of our police officers, Tao Qixun, and you stabbed him. A charge of assaulting a police officer is enough for you. "

"The girls you killed are all of the same age as Hua. They have no grievances against you, but they have become your soul. Besides, have you ever thought about what your old mother should do after you have killed someone and been arrested? She adopted you since you were very young, so that you can kill someone when you grow up?" Cao Wei was also asked about Mao by his silence. He got up angrily, pointed at him and scolded him loudly.

Song Jingan was calmer. Although she was angry at his silent attitude, she was still rational. She said coldly, "it's all like this. Do you really intend not to say anything?"

Jin Yishuo looks at Song Jingan and is indifferent to Zhang Mingcheng and Cao Wei's words. But after hearing song Jingan's words, he laughs ferociously: "I have nothing to say. I can kill whoever I want. It depends on my mood. If I have a chance, I want to kill you. Officer song, ha ha ha ha ha!"

"Say it again, you son of a bitch." After hearing this, Zhang Mingcheng red eyes, rushed over and grabbed his collar.

"Ming Cheng, come back." Seeing this, song Jingan looks at Zhang Mingcheng and calls him back.

Zhang Mingcheng was very unwilling to let go of Jin Yishuo and returned to his seat.

Song Jingan glared at Jin Yishuo's eyes deeper and deeper, played with the pen in her hand, and snorted: "Jin Yishuo, a person of your profession, should be confident and proud. In fact, the relationship between you and your mother is not as good as it seems, right? You're estranged from your mother, aren't you? "

Song Jingan knew that since she couldn't cut in from the case itself, she had to go around with him and hold the point he cared about most.

"Ha ha ha! She doesn't love me at all. What she loves is only herself. She's the one who's harmed me when I'm like this. If I knew that I would be like this, I might as well hope that she didn't adopt me at the beginning. All motherhood and filial piety are farts, ha ha ~! "

Song Xian'an squinted. Seeing that Jin Yishuo was finally willing to speak, she continued to ask around this question, and gradually approached the topic of the case itself.

Looking at the whole process of Yang detachment in the monitoring room and song Jingan's ingenious interrogation method, he nodded with satisfaction: "it's better for her to be more skillful. Mingcheng and Cao Wei are too anxious. They are short of some heat. We have to have a good experience with her. We are police officers, In the future, we will definitely face more suspects like Jin Yishuo or those who are more reluctant to speak. We have to start with what they care about to win at one stroke. "

When Jin Yishuo was interrogated at more than two o'clock, song Jingan, Zhang Mingcheng and Cao Weicai came out of the interrogation room and said, "Mingcheng, go and sort out Jin Yishuo's confession. Cao Wei, go to the traffic police brigade and drag the two cars that Jin Yishuo has just given to the team for inspection." With that, song looked at Tian Yan in front of her and waved to her: "Tian Yan, now go to the inspection department and the forensic department to see if the inspection report has come out. After forming a chain of evidence, submit it to the procuratorate as soon as possible. Today, the inspection department and the forensic department are working overtime. I'll go to the Yang detachment."

"Good."

Zhang Mingcheng, Cao Wei and Tian Yan went to work after listening.

And song Jingan went all the way to Yang's office and told him about the interrogation results of the night: "do you mean that the tips of the two emails he sent us say that the next target is Fu qihan?"

Song Jingan nodded: "this is our negligence. We've always set the scope on Jin Yishuo's killing other girls. We completely forget that Han Han is also his target. According to the tips he gave, it's true that there is a very big apple retailer near my home, and Jiang is very close to my home, which is just two roads away."

"Team Yang, I have an invitation."

"You said

"I want to ask a psychologist to see Jin Yishuo."

"What do you mean? Suspect him of mental illness? "

"That's not true. He's in a normal spirit and his logical thinking is extraordinary. I just think... His heart is very distorted. He's not on the same channel as normal people when he looks at problems. Moreover... According to the last visit to his mother, he often buys live fish and chickens to kill, especially after the fourth case, During the period when we monitored him in all aspects so that he could not commit a crime, the old lady said that he would buy two live chickens or fish to kill in a week. She said that there were a lot of chickens and fish left in the refrigerator, but he still bought them. I think... He was a bit twisted in his heart, or even addicted to killing. "

"The addiction to killing?" After listening to these four words, Yang detachment could not help but feel chilly: "this kind of thing should be rare! It shouldn't be

"I'm not sure, so I want to see a psychologist tomorrow."

"Well, it's up to me."

Song Jingan nodded: "well, after the psychiatrist has diagnosed him tomorrow, I will be able to write the closing report, and he has also told me the process. The evidence is solid, and without any accident, I will be able to submit all the information to the procuratorate tomorrow."

"OK, that's good. This serial homicide case has finally been solved. I'll go to the Bureau tomorrow and invite you to eat Haidilao tomorrow evening."

"Well, I'll thank Yang detachment for the team first."

"By the way, how is Tao Qixun's injury? I heard that he was still in hospital. Is it serious? "

"Mingcheng said that the wound was very big and had been sutured. But the doctor said that he would have to observe in the hospital for a few days. He said that it was about an hour from the stab wound to the hospital. He didn't say a word. He was bleeding too much and his face was very pale. So I asked him to take good care of his injury and give him sick leave. I'll go to the hospital to see him after the case is finished tomorrow."

Yang's detachment nodded: "in this way, I'll apply for his medical expenses. After all, he was injured when he was on duty. It's a work-related injury. Moreover, he made great contributions to the arrest of Jin Yishuo and let him rest for a few more days. Although Tao Qixun is a newcomer, he is not familiar with any old criminal police. Tomorrow, when you are finished, come to my office and I'll go shopping, You bring it to him for me. "

"Team Yang, no, we're going to..."

"It's like I'm not your own person. I assigned Tao Qixun when he entered your team. Now he's injured. Although I don't have time to visit him, I always have to buy something with my heart. Otherwise, I'm too embarrassed to be a leader."

"Well, I'll thank Yang detachment for Qixun first."

Yang detachment waved his hand with a smile: "since the serial homicide appeared, your team has not had a good rest. It's the last time. It's good to be busy. It's hard for you."

"Team Yang is polite. Doesn't team Yang often stay up late with our team? I ask you many times. You will try your best to help me

"What you said, you are the people I brought out, and they are related to the case. Of course, you have to do your best."

"Thank you, team Yang, for your trouble. It's not too early at this time. Go back and have a rest as soon as possible! I'll go back to the team first

"Well, go! Pay attention to your body, too, you know? "

"Well, all right."

All night long, song's team had another sleepless night. All of them were busy with the case of Jin Yishuo. They were completely indifferent to the ground.

At about 10 o'clock the next morning, the psychiatrist arranged by Yang detachment arrived. Song Jingan arranged a small room for them, and let the psychiatrist and Jin Yishuo one-on-one. In order to have a better effect, song Jingan and Cao Wei stood outside the one-way glass window and looked at the situation inside.

Because Jin Yishuo is quite special, in order not to let him hurt the psychiatrist, they also put his hands and feet on a fixed chair.

Song Jingan is watching outside. In the psychotherapy of the psychiatrist, Jin Yishuo often laughs ferociously, sometimes he is very quiet, and even covers his face and cries in the middle of the way. It can be seen that she and Cao Wei are confused and completely confused.

Cao Wei also said a sarcastic remark: "I didn't expect that Jin Yishuo would cry. Last night, the evil force and ruthless force disappeared. This psychologist is really powerful. I suddenly want to experience it. Team song, is this psychologist charged by the hour? How much is an hour? I also feel that I've been tortured by Jin Yishuo for a long time. I feel that I can't bear it any more. I have to find a psychologist to explain it. "

Song Jin'an smell speech, cold eye pass past, can't help but turn his one eye, in the vision is permeating continuously cold fierce.

Seeing that Cao Wei's back was shining, he quickly gave her a smile, waved his hand and said, "ha ha, I'm kidding. Song team, don't take it seriously and don't look at me like this. I've got goose bumps."

Song takes her eyes back indifferently and finds that the one-on-one diagnosis is over. She gives Cao Wei a color and walks to the door together. Cao Wei and another young male police officer press Jin Yishuo to return to the detention room. Song goes to the psychologist and makes a "please" gesture to her.

"Dr. Jiang, this way, please. Go to my office and talk about it."

"All right."

As she approached her office, when Tian Yan came to the door, song stopped and said to the psychiatrist, "Dr. Jiang, please understand. We have regulations that more than two people must be involved in the investigation."

"No harm, Captain song is polite." Dr. Jiang is also a young woman with extraordinary temperament and great manners. He smiles at Song Jingan and walks into the office.

After they were seated, song asked, "Dr. Jiang, how is Jin Yishuo?"

"Jin Yishuo's heart is extremely distorted, which may be caused by his family environment. He is extremely eager to be recognized and loved. Moreover, in the process of chatting with him, he said that he likes the pleasure of killing animals, especially when he plunges into a fresh life and sees the dark red blood suddenly emerge, he will have a great sense of achievement, He called the girls he killed and all the creatures works. According to our psychology, action / state orientation, he filled his empty and extremely loveless heart through such behavior. "

"Why, such a pervert?" After listening to Dr. Jiang, Tian Yan felt that he had goose bumps, rubbed his arm, and smashed his mouth.

Dr. Jiang smiled and nodded: "according to the thinking of normal people, this is really a more abnormal kind."

Later, Dr. Jiang talked with them about Jin Yishuo's illness. After more than half an hour, Dr. Jiang got up and took out a business card from his bag and gave it to her: "if there's nothing wrong, I'll go first. If there's anything wrong, Captain song can contact me at any time. This is my business card."

Song Jingan nodded, showing a faint smile: "well, today is really thanks to Dr. Jiang."

"Captain song is polite. That's what I should do."

"Tian Yan, go and see Dr. Jiang off."

"No, no, I'll just go by myself. You are all busy people, so I won't delay you."

"Well, Dr. Jiang, take your time."

After seeing Dr. Jiang leave, song Jingan sighed, but Tian Yan sighed: "I think Jin Yishuo is both pitiful and hateful. Because of his twisted heart, he has killed so many innocent lives. It's just appalling."

"Well, this case has finally come to an end, and I can rest assured to write the closing report. You and Mingcheng and Cao Wei say that after a tired night, you will take a hot bath and have a good sleep."

"That means, can we get off work now?"

"Well."

"Yes! I haven't been off duty so early for a long time. Just now Mingcheng and Cao Wei are still talking about going to see Qixun at noon. "

"Well, I'll go back in the afternoon. I'll write a closing report later, and I'll report the end of the case with Yang detachment."

"OK, I'll go out first. Song team, you should finish your work earlier and go back to rest!"

"Well."

Tian Yan happily steps out of the office. Song Jin'an gets up and walks to her desk, takes her cup to the water dispenser, and pours herself a cup of warm water. After two drinks, she sits in her chair, typing on the computer, ready to make a closing report on the case.

After he was busy, he asked another policeman in the team to send all the information and reports related to Jin Yishuo's case to the procuratorate. Of course, Jin Yishuo was also detained to the procuratorate.

It's only half an hour since Jin Yishuo was taken away. The news that the serial murderer was arrested exploded on the Internet and on TV. Looking at those reports, song Jingan suddenly thought of Jin Yishuo's old mother. She pursed her lips and wiped her deep meaning through her eyes.

At noon, song Jingan went back to her apartment. Looking at the scene of the fight, she sighed and began to clean it up. She didn't clean it up until about one o'clock. She ordered the takeout and took a hot bath. The takeout just arrived. She took a nap for more than an hour. After getting up, she went out again and drove to the zijingyuan community, Jin Yishuo's family visited his elderly mother. When he passed a fruit shop on the way, he bought some fruits. Especially when he saw the apples, he looked awe inspiring. After a few seconds, he chose some apples.

It was already half past three when he arrived at Jin Yishuo's home. A middle-aged woman came to open the door. Song Jingan was stunned. The middle-aged woman nodded and asked, "Hello, who are you looking for?"

"Is Mrs. king at home?" Song Jingan came back and asked in a low voice.

"The old lady is here. Who are you?"

Song Jinan took out a black certificate from her pocket and opened it for her to see: "police, I have something to say to the old lady. Come and see her by the way."

"Come in, please. The old lady is having tea in the living room."

When song Jingan came into the room, the middle-aged woman took the two bags in her hand and went to the living room: "old lady, Youwei police have come to see you. They say they have something to tell you."

When the old lady heard the speech, she looked sideways and saw that it was song Jin'an, with an easy-going smile. She also noticed that the middle-aged woman still had two bags in her hand: "it's officer song. Officer song is here. How can she spend so much money?"

"There's nothing to spend." Song Jingan sat on the single sofa: "but I'm bothering the old lady again."

"Officer song, you're welcome." The old lady looked at the middle-aged woman: "Mei Fen! Please pour a cup of tea for song police

"Yes."

The middle-aged woman pours a cup of hot tea for song. Song reaches for it and says "thank you." then the middle-aged woman goes to the kitchen instead of staying in the living room.

"Old lady, was that

"Oh! Officer song means Mei Fen! She's my new nanny. She's looking for my food and daily life. You know, I'm old and my legs are not very sharp. I've got a cold today. I can't walk straight now. "

Looking at the old lady's sad face, song asked tentatively, "old lady, have you seen the news? About Jin Yishuo. "

The old lady raised her hand to stop her from going on. She nodded and said sadly, "after reading the news, I can't get up directly. At noon, the family doctor came to see me. It's better to have an injection and take medicine."

Song Zian pursed her lips, and she could see that the sadness and sadness of the old lady's eyes were true. She asked curiously, "old lady, can I ask, what's the difference between Jin Yishuo and you?"

"This is a long story. When he was a child, he was very obedient. He was very good. He was always the first in class. He looked handsome. At that time, I was trying to spell his career. I didn't have much time to control him and let him live in lodging. As a result, he was subjected to campus violence in school. When he was fourteen years old, he was wounded in hospital with his classmates. I was in the field at that time. I didn't go back in time because of my work. I went back on the third day of his hospitalization, but at that time he began to be silent and didn't like to talk to me. The estrangement was only at that time. I regret it! If I had known that my little action could cause him so much damage, I would have taken it with me even if I lost my job. " With that, the old lady began to wipe her tears, her eyes full of remorse.

After hearing this, song Jingan also understood why the psychiatrist said that Jin Yishuo was extremely insecure and cared for. It turned out that at that time, he closed himself up and felt that he was adopted, which was not so important. Everyone didn't love him, and the psychological distortion also came from that time!

"Officer song, can I ask, how many years will Yishuo be sentenced if he is arrested?"

Looking at the old lady, song Jin'an looked serious and serious: "this kind of thing is not what we police say. It needs to be judged by the court, but... He has four days of young life on his back, and the nature of the case is extremely bad, especially the last girl, who is only 17 years old, was killed on the way back from cram school, If she didn't die, she would be a college student next year. "

"Yes! Yes! Yes After listening to this, the old lady felt very sad, trembled and nodded: "one life pays for one life, which has always been the case since ancient times, not to mention four lives. It is said that there is a girl who is seriously injured in the hospital. After all, I can't wait for him if my body is half buried."

"Please take care of yourself, old lady."

"Thank you for your concern."

"Officer song, can I see Yishuo? He's been away for ten days and a half months. It's the last time I've seen him. "

"This... Person has been sent to the procuratorate today. I can't be the master."

"Well! That's embarrassing officer song. "

Looking at the old lady's sad appearance, song Jin'an got up slowly and didn't plan to sit for a long time: "old lady, you have a good rest. I'll go first and come to see you another day."

"Well, thank you, officer song, for coming to see me." The old lady wiped away her tears and nodded: "Mei Fen! Come out and see officer song off. "

After leaving Jin Yishuo's home, song Jingan directly took the elevator to the first floor. When she came out of the corridor hall, she just walked out of the corridor hall with a touch of familiar Wei'an Junying. Song Jingan's step at her feet made her face a little stunned.

Fu Jinheng, who just came out, quickly saw song Jingan. He stepped on her high-grade shoes and stopped. His handsome outline rose, and he put his hand into his pocket. He glanced at the building behind her and deliberately lengthened the ending: "Hi, song police officer, what a coincidence!"
