Professor Qin's wife covered her face and cried, Professor Qin hugged her comfortingly, and whispered in her ear: "I don't blame you, I really don't blame you." ”

Li Jing looked at Professor Qin comforting his wife, he sighed, and then said, "Looking at your current situation, it should be impossible to continue, then I will continue to explain the rest of the matter." Speaking of this, he turned to Aunt Wang again, "Aunt Wang, one last question." Did you have a physical examination a few months before Jin Fengxia's accident? ”

Aunt Wang thought for a while: "Ah! That's right, we had a medical check-up 3 months before her accident. ”

"When and where is the medical report?"

Aunt Wang was vague: "It seems to have been given to us one month after the physical examination." ”

Li Jing thought for a moment: "Then did she talk about her cancer?" ”

"Nope." Aunt Wang waved her hand without hesitation, "Absolutely not." Although she always took time off work because of her stomach pain at that time, she never told us about her cancer. We all knew about it when she was released on medical parole after her accident. ”

"Thank you." Li Jing smiled politely, and he turned to us, "This is Jin Fengxia's motive. ”

"Motivation?" I asked.

"Yes, there are two motives in this case." Li Jing drew it with his hand, "One motive comes from Professor Qin, this is the motive for the murder of Xu Zilong, I will explain it later." The other is Jin Fengxia's motive for killing, and this motive is the question I just asked about Jin Fengxia's illness. ”

Except for Mr. Lu and Team Xiao, we all had confused expressions, and we didn't know what tongue twisters Li Jing was talking about.

Li Jing looked at Professor Qin: "Professor Qin's motives also start from 20 years ago, when you had a sister to be married, but your sister died suddenly 21 years ago. The explanation you gave was that it was a death, and I went to check the police records with the attitude of giving it a try, only to find out the real cause of your sister's death in the file left by the medical examiner. Your sister died by suicide with lacerations on her lower body, and she was judged to have been violated before committing suicide. At the place where the family signed the autopsy report presented by the police, you did not prosecute anyone, refused to be pursued by the police, and quietly arranged for your sister's burial. Half a year later, Xu Zilong died, and I handed over the DNA of the remnants of your sister's lower body extracted from the death report and the DNA recorded in Xu Zilong's death report to the technical department for comparison again, and found that both DNA copies belonged to the same person, so your sister committed suicide because she was violated by Xu Zilong. That's when your father starts to get confused. ”

Professor Qin kept his eyes red and didn't speak.

Li Jing shifted his gaze and looked at us: "If my guess is correct, since that time, Professor Qin has been planning to take revenge on Xu Zilong, but because you still have your own family to maintain, you can't really implement your plan. But you stumble upon the news that your neighbor Jin Fengxia is suffering from cancer. A plan is formed from your head. You take advantage of Jin Fengxia's love for her son, Jin Fengxia knows that she has cancer, but she is worried that she will have no one to take care of her son Jin Yuan after her history. So you took this opportunity to discuss with Jin Fengxia, let Jin Fengxia kill Xu Zilong for you, avenge your sister, in exchange, you will take care of her child for Jin Fengxia, but if it is only your husband and wife who come to talk about this child, it is very likely that outsiders will see the clues. In order to avoid arousing the suspicion of others, you found an adoptive family for Jin Yuan with the same conditions as yours. Xu Zilong usually bullied Jin Fengxia's mother and son, providing enough motivation for Jin Fengxia to kill. ”

Everyone's eyes were fixed on Professor Qin, but everyone's eyes were complicated when they looked at him, mixed with anger and pity.

However, there was still one thing I still had doubts, so I asked Li Jing: "But why did they wait so long to turn themselves in?" You can turn yourself in directly after killing someone. ”

"Blurring the time of death." Li Jing turned his gaze to Professor Qin, "I don't think there should have been just an episode on the day of the incident. It is very difficult to kill a man who often does hard work with the strength of a woman, and it is difficult to do it alone without helpers. So Xu Zilong's murder was done in two parts. It was Jin Fengxia who gave the fatal injury, but it was you who subdued Xu Zilong. So in order to make a perfect alibi for yourself, you need Jin Fengxia to help you confuse Xu Zilong's time of death. You are a university engaged in biological research, for temperature changes in the temperature and characteristics of corpses. You use the cold air of the refrigerator to delay the stiffening of the body, after which you leave the scene of the incident and take your wife to the hospital to make yourself a perfect alibi. After you returned home, you happened to receive a call from Jin Fengxia to tell you about Jin Yuan. You went to school in a hurry, because your university usually has public exhibitions, or free extracurricular classes aimed at cultivating children's interests, and you have many legitimate reasons to enter the school and use the phone number of the teacher's office to confuse the police to collect evidence in the later stage. Because it happened suddenly, you left a handle for the future. After dealing with these things, you go back to the place where the incident happened, close the refrigerator door, take care of the scene, and go back to your own home. Waiting for Jin Fengxia to play the follow-up things. ”

Professor Qin let out a long sigh of relief: "There are some words that I have always planned to bury in the loess with me, but now it seems that it is really impossible. That's right, I asked Feng Xia to help me kill Xu Zilong back then. ”

"No, it's not." His wife opened her mouth to deny, "It's me." ”

"Don't say it, Xiaoyun." Professor Qin interrupted his wife's words, "I am the one who thought of this plan, and I am the one who will implement it in the end." You don't always blame yourself for all your sins. Besides, didn't you stop me then? I was bent on using Jin Fengxia to kill Xu Zilong to avenge my sister. ”

Hearing Professor Qin say this, everyone present gasped.

"But if I could go back in time." Professor Qin's wife wet her eyes as she spoke.

"That's none of your business." Professor Qin looked at his wife, and then at us: "21 years ago, my little sister went to my house as a guest, and met Xu Zilong in the courtyard. Xu Zilong followed my sister to my door. My wife and I were at work at the time, no one was home, and by the time we got home, my sister had already committed suicide at home. My wife was working overtime at school that day to do research, and she had been blaming herself for all these years that if she had been there, it might not have happened. But there's nothing we can do to change the past, can we? When Professor Qin said this, he first asked us, and then he seemed to be talking to himself.

Professor Qin paused for a moment before he slowly spoke again: "I just didn't say anything because I wanted to leave my sister with the last dignity, and I promised my father that I would definitely avenge my sister." After burying my sister, I have been looking for an opportunity to kill Xu Zilong quietly, but I have never found a suitable opportunity. Then one day, my wife was not feeling well, and when I took her to the hospital, I accidentally saw Fengxia crying. We didn't think about it, but we didn't know why, we just couldn't help but want to get close to her, probably because of the same sad mood. Feng Xia didn't tell us about herself at first, but maybe she needed to talk too much, so she finally told us about her cancer. When I heard that she was worried about Jin Yuan's future care, I suddenly wanted her to help me with all my plans. I didn't expect her to say yes so happily, I underestimated the power of a mother. She can really make any sacrifice for the sake of her children. She killed Xu Zilong according to my plan. In the early morning of the day of the incident, Xu Zilong returned to his home, Feng Xia knocked on her door, Xu Zilong was lustful, and let her enter the door without thinking about it, Feng Xia pretended to help him close the door, but in fact he just covered the door, and I then entered Xu Zilong's house. subdued Xu Zilong, and Feng Xia killed him. Feng Xia didn't blink her eyes when she killed him, maybe it was out of hatred for Xu Zilong, or maybe it was out of protection for Jin Yuan, because the first thing she said after killing Xu Zilong was to ask me, 'When will you help Yuan Yuan go through the adoption procedures'. Speaking of this, Professor Qin choked up.

I saw that Grandma Li's eyes were also red.

After a pause, Professor Qin said again: "The next thing is basically the same as what Li Jing said. Because a lot of water will flow out of the refrigerator door for a long time, I specially set up Xu Zilong's body lying flat on a chair, spread plastic sheeting on the chair to prevent unnecessary marks, and finally I disposed of the ground. Because it was a weekday morning, no one paid attention to me. After a pause for a few seconds, Professor Qin sighed deeply, "Hey. After that incident, there was not a day when our whole family was not tortured in the depths of our hearts, my father knew that Feng Xia was dead when he was in a trance, and before he passed away, he still told me on the sickbed that the most regrettable thing in this life was to listen to my words in a moment of confusion and kill two people. And my wife, who blames herself every day for everything that happened back then, and has been suffering from depression ever since. I myself regret what happened back then every day, after Jin Fengxia was imprisoned, I didn't go to see Jin Fengxia, I didn't dare to look her eyes, and I didn't even dare to look at the eyes of his son Jin Yuan. I didn't have the courage to face my cowardice and selfishness back then, and I used her child as a bargaining chip to use an innocent woman to kill someone. We found a colleague couple as his adoptive parents, on the one hand, so that we would no longer be involved in Xu Zilong's death, and on the other hand, we really couldn't face that child. Every time we see him, we are reminded of our mistakes and cruelty back then. ”

After speaking, Professor Qin lowered his head again, and Mrs. Qin was still sobbing. We looked at them, but we couldn't say anything.
