The murderer's method of murdering O Na has already been guessed by us, so the alibi was also debunked by us, in fact, we could have told the police about our speculation at that time. But.

"But you lack evidence." Li Jing looked at me coldly, "So you only told Gong Xiaohuan's parents about the results of the investigation at that time." ”

"You know the case." I stared at Li Jing in surprise.

Li Jing nodded: "I saw it when I was sorting out the unfinished files, and I felt very suspicious when I saw it, but I haven't made time to study it, but I didn't expect you to have a connection with this case." Indeed, Wan Xue's murder plan misled the entire direction of the investigation. Because the blade fell on the inside of the bath, all the fingerprints on it were washed. It is precisely because of this, but it can only be identified as a murder weapon based on the bloodstains on it, and the scar on Ou Na's wrist is completely consistent with the shape of the murder weapon, and there is no reason to deny the possibility that it is a murder weapon. After falling into the blood, only Ona's own DNA remained on the blade. But it was because all the signs indicated that the blade that fell in the bathtub was a murder weapon, which made us feel very good, as if the murderer had deliberately placed it inside. and the Arabic numeral '3' written in Gong Xiaohuan's blood on the bathtub tiles at that time made people think that it was the same killer, so he was treated as a serial murder case at that time. And didn't the fourth deceased Liu Yiyi be found in the end? So who is Wan Xue allied with to commit the murder? Li Jing sneered and looked at me.

I don't want to be a flash, I have always had a strong sense of guilt about that case. I didn't finish talking just now, for Liu Yiyi's death, Ban Que and I have always blamed ourselves for our own decisions at that time. After we investigated the truth of the first three cases, we did not notify the police directly, but took the results of the investigation to find Gong Xiaohuan's parents. Did you know that once the human heart becomes greedy, it becomes even more terrible than the devil? No amount of excuse can explain the fact that we sold the results of the investigation to Gong Xiaohuan's parents in order to get more remuneration, causing Liu Yiyi's death.

Whenever I think of this case, the uneasiness in my heart becomes more and more intense, although we didn't do it, but it was indeed our cause that led to Liu Yiyi's death later. Li Jing and I became demons, neither of us wanted to say the first word, I knew it was an unforgivable mistake, and I also knew that Li Jing was struggling in his heart, and after we investigated privately, we sold the results of the investigation to the victim's family, causing new deaths, and Ban Que and I were mainly responsible, and Li Jing should hate me very much.

After ten minutes of silence, Li Jing finally spoke, but it was not the scolding I imagined: "You haven't explained Liu Yiyi's death yet." Although the police closed the case, according to Liu Yiyi's suicide note, Liu Yiyi was sentenced to be beaten by Gong Xiaohuan many times, so he murdered the first three deceased. The suicide note was written by Liu Yiyi herself, and a handwriting appraisal was done. But the police still attributed him to an unsolved case because Liu Yiyi mentioned her husband Gong Xiaohuan and the other two deceased killed by hired killers, and then couldn't stand the condemnation in her heart and chose to understand her own life. But because the killer written in Liu Yiyi's will has not been found, the police have not closed the case. According to the results of your investigation at that time, it seems that Liu Yiyi took all the charges off. But since he doesn't have any doubts about him, and Liu Yiyi is relieved after her husband's death, she can start a new life, why should she choose to commit suicide? He could have gone to another city, or even another country, and lived a new life, instead of turning himself into another victim with his husband's blood again. ”

"There's no way she's going to kill herself." I shook my head, "She has already completed the procedures for going abroad, and she is ready to flee abroad as soon as things cool down, she should want to live incognito abroad." So he had no intention of committing suicide at all, and when I asked about it, I felt guilty about his death. I can't say that I am trying to bring the murderer to justice, after all, as I said earlier, we sold the results of the investigation to Gong Xiaohuan's parents at a high price, after all, they have been desperate to find out the cause of their son's death. But we didn't think about letting Liu Yiyi die. We just wanted to make money, and we didn't even think about killing people. When I bought it for his parents, I was already waiting downstairs at Liu Yiyi's house for the moment when Gong Xiaohuan's parents knew the truth, and when I went to find Liu Yiyi's theory, I called the police to notify the police to stop things from getting worse. After that, Liu Yiyi was interrogated, and the truth of the matter would naturally be revealed, after all, we did not have any evidence in our hands, and telling the truth would only be ridiculed as whimsical madmen, and the victims' families would not pay attention to these at all. We took advantage of other people's feelings, so in the end, Banque and I suffered retribution. In fact, taking this case, it was like a trial for me and Ban Que in the dark, we used other people's feelings to get rich, and then God brought retribution to my relationship with Ban Que, and cut off our feelings with death, so I don't need to get other people's sympathy at all when I think about it, but it's all my own doing.

I looked at Li Jing, he didn't speak, and after a while, I realized that I seemed to be off topic again. I glanced at Li Jing apologetically, and then talked about the rest of the matter.

After Ban Que sold the results of the investigation to Gong Xiaohuan's parents, Gong Xiaohuan's parents took a bunch of relatives and ran to Liu Yiyi and Gong Xiaohuan's residence that night to avenge their son. When I saw Gong Xiaohuan's parents at that time, I felt in my heart that I could educate that kind of scumbag son, and sure enough, the parents themselves had problems. Gong Xiaohuan betrayed Liu Yiyi and became a scumbag playing with women, his parents actually ignored their son's scumbag behavior and attributed the fault to others, even if Liu Yiyi was really the murderer of their son, they also needed to apologize to Liu Yiyi, after all, it was Gong Xiaohuan who did something very excessive to his wife Liu Yiyi, and for his son beating Liu Yiyi, Ban Que said that Gong Xiaohuan's parents did not feel any guilt for their son's bastard and lack of tutoring. But even if Ban Que doesn't say it, as long as I see the rude attitude of them who appeared in the Liu Yiyi community at that time, I can guess a few points.

I hid in a more private corner, waiting for them to enter the apartment building, so I called the police, and the police arrived quickly, when Gong Xiaohuan's parents were about to kick in the door, but before the police successfully went up to stop them, I heard Gong Xiaohuan's mother's shrill screams, and then I saw several men who came with Gong Xiaohuan's parents running down the stairs in a panic. Because the movement in the apartment building was too big, it also attracted many residents in the apartment to see the excitement, and then the ambulance also came, and soon the medical staff carried out several stretchers. At that time, I didn't realize that something was wrong, I just thought that Liu Yiyi and Gong Xiaohuan's parents had a fight and caused harm.

But I thought it was unscientific, and when I looked at the people on the stretcher covered with white cloths, I was dumbfounded, and then, when Gong Xiaohuan's mother and several other female elders and family members of Gong Xiaohuan who went to make trouble were also carried out, I heard the fact that Liu Yiyi had died from the mouths of the people around me who were watching the excitement.

I was really stupid at the time, and I thought it was because we gave Gong Xiaohuan's parents the results of the investigation, and Liu Yiyi, who directed it, died. But the dead end is still more terrible than I imagined, the reason why I heard Gong Xiaohuan's mother's screams. In fact, when Gong Xiaohuan's parents rushed to Liu Yiyi's apartment, Liu Yiyi had already committed suicide in the apartment, and a big Arabic numeral '4' was written in Gong Xiaohuan's blood on the wall of the room where he committed suicide.

Although everyone thinks that Liu Yiyi committed suicide, and Liu Yiyi carried all the entourage on herself, I always felt that something was wrong, the number '4' appeared very weird and redundant, as if someone deliberately pushed everything to Liu Yiyi. Although you say that the artistic handwriting has been determined to be written by Liu Yiyi herself, in fact, this does not completely prove that Liu Yiyi's death was a suicide. She doesn't need to disguise herself as the last victim, just leave a suicide note, why do she write a number upwards in one fell swoop, and she actually used art to change the direction of the investigation in another direction, obviously hiding Wan Xue's traces, is he really that good with Wan Xue? Can you use death to fight all the crimes for Wan Xue? I don't think so, Liu Yiyi has already prepared the soup bowl before Brother Mingming.

"So you re-investigated the case." Li Jingdi gave me a glass of water and a few pills.

I looked at him quizzically.

She frowned and was a little impatient: "The doctor asked you to eat, not me, you don't have to be aunty, I will drug you, if I suppress the pressure and am afraid of putting you Liu Ziang around, do you think you can escape a few times before?" ”

I no longer doubted it, obediently took the medicine and continued to talk about the later investigation.

In fact, there is still a particularly big suspicion in the first three homicide cases that we didn't find, that is, the numbers left on the wall, and another common feature of these numbers is that the paint written is from Gong Xiaohuan's blood. We have not investigated the source of this pigment, and neither Liu Yiyi nor Wan Xue has direct evidence that the blood came from them. So the source of the blood became the focus of our investigation at that time.

Gong Xiaohuan is not a big person, no one will buy his blood, so there is no channel to buy it. Some people in the underworld will be able to help buyers get the blood of some non-big people, in order to test whether the blood can be successfully matched with the blood that the buyer needs. So there are still purchase channels. I did find a bag in the black market at that time, hoping to get a channel to buy it for my studies, but the asking price for us was very high, even more than what we got from this case investigation. Don't think of us as the Virgin, we are not good people, even if we are ashamed, but if we lose money to do business, we absolutely cannot allow it. So we gave up on buying channel sources at that time. Bao inquired to see that the business was about to end, so he thought about talking about the price again. As a result, I didn't take the things in my hand at that time, so that Wan Xue's photo flew out of the notepad, and when Bao inquired and saw Wan Xue's photo, his expression was very unnatural.

Ban Que asked Bao if he knew Wan Xue, and Bao asked us anyway, and he could see that he wanted to leave, so he no longer negotiated the price with us. Ban Que and I didn't threaten him, we just let him go, you know, in a place like the black market, it's useless to threaten people, and it can even cause trouble. We just want to know the truth, so there is no need to entangle with the black stone, but after the windfall of 'Wan Xue once came to the black market', the subsequent investigation has been much smoother.

Although we are not sure if Wan Xue came to the black market to buy Gong Xiaohuan's blood and wrote the numbers left at the crime scene, we are sure that it must be related to Gong Xiaohuan's case. No matter what happens in this world, there are some invisible transactions, such as the underground human organ trading market, and there will always be some inhumane bloody and terrorist transactions in these places. If Bao Inquire has indeed seen Wan Xue, and if Playing Snow has indeed bought Gong Xiaohuan's blood, then even if we don't have access to the black market, we can still get the news we want in this underground market.

Even now, selling blood is one of the most basic ways for some poor people who are desperate to get a living. We went to the slums of this city. Most of the people living here are incapacitated old people, and children under the age of twelve, their shabby clothes cover their skinny bodies, they look at you in rags, but they have absolutely no intention of reaching out to you to ask for money, they retain their only remaining dignity. It's just that when they hear the word 'sell blood', you can find that especially those old people, there seems to be some more light in their dim eyes because of these two words, which is one of their few incomes. It was only when we mentioned the place where blood was sold that the old men fell silent again, and some of the children wanted to sue us, but they were all reprimanded by the old men. We know he's afraid that we're journalists or whatever, and they're not willing to cut off their income.

After we repeatedly assured that we were inquiring about buying blood, the expressions of these people became gentle again, and some people even asked me what kind of blood type I needed, and the blood type of Gong Xiaohuan I had seen before popped up in my mind. After learning about our needs, they set us up and went to an underground blood buying station in the hope of being able to trade directly. When we went to the underground exchange with them, I saw a doctor, and I was impressed because it was a doctor in the hospital where we had been an alibi before. He didn't know us because we had been quietly investigating, but she still had a wary look on her face when she saw us, maybe we really didn't look like the people who had come to buy plasma. Ban Que had to lie that his mother was seriously ill, and when the blood bank was in an emergency, he deliberately looked for an underground market to buy it, and the doctor calmed down. And after making an appointment with us to come and buy, we came out of the underground market.

After giving the old man who brought us some money, the old man stopped us and said that he knew that our roots were not customers who came to sell blood, but I thought he would expose us, we were not far from the black market, and we were afraid that the old man had already notified the bodyguards of the black market, and if someone came around at that time, I am afraid that we would be very lucky.

But the old man didn't do that, but asked us what we were here for. The old man stared at the money in his hand and said that he was not a beggar, so he would not accept alms from others for no reason, except that the doctor would sell us blood, and he would also think that the extra money would be paid for his work, and he would not get it for nothing.

I exchanged ideas with Ban Que at that time, and then agreed to the old man's request, so I took out a photo of playing in the snow and asked the old man if he had seen Wan Xue. The old man shook his head and said that he had not seen the woman on the sign, but promised that we could help us to ask the others, but in exchange we would help a few of the children near his house find a school. After the quid pro quo was met, we got new information on the day we bought blood.

The old man told us that someone in the slum had seen the woman in the picture here and the doctor who used to buy blood (the one we saw last time) had obtained a test tube with blood in it, and left in a hurry. Then the old man gave us back the money, saying that since we did not come to sell blood, there was no need for him to covet our money, and he said that his blood should be reserved for those who really needed it, and that he could not buy it for long, and that he could not waste it on us, but he could not take our money in vain. In the end, at the insistence of the old man, we still took the money back, although we are not good people, but we are not completely inhuman. After that case, we did help some of the children there find schools and welfare institutions that were suitable for them, but that's for another time.

After we got the news from the old man, we confirmed that Wan Xue had purchased Gong Xiaohuan's blood, and the blood was only stored for a maximum of 35 days, and the ingredients in the preservation solution had to be controlled, so if the juice was an ordinary person with little experience, the blood should be kept in their hands for less than 21 days, plus Gong Xiaohuan had no record of massive blood loss for several weeks before his death, so at that time, we locked our eyes on the physical examination that Gong Xiaohuan participated in the day before he was killed. And according to the old man's description, Wan Xue's tubular container is indeed very similar to the anticoagulant tube used to draw blood during the hospital examination, and if the anticoagulant tube is used, because it is a small dose of blood, taking out an extra tube will not have any effect on Gong Xiaohuan at that time.

So it also explains the mystery of the numbers that appeared at the scene, all the blood was obtained from Wan Xue's hands, and the same is true of Liu Yiyi's death scene, so we are more certain that Liu Yiyi's death is likely to be directly related to Wan Xue. Wan Xue is likely to be the murderer of Liu Yiyi, but we don't have any evidence to support our speculation. Especially the suicide note found by the police at the scene of Liu Yiyi's death, as you said, even the handwriting was written by Liu Yiyi himself after identification, and our speculation is likely to be completely overturned.

"So you didn't say anything to the outside world, and let Wan Xue go unpunished until today?" Li Jing's expression looked very bad.

I hesitated for a moment before saying, "No." ”

Li Jing frowned slightly, as if he didn't understand what I was talking about: "No?" ”

"Wan Xue is dead." I pondered my words, "We were going to borrow this case so late." But when we were awesome when the kids contacted the school, the old man inadvertently asked us if the problem was solved, and we didn't call for a while. The old man didn't know that the late school in the photo had anything to do with the murder, but he was a little worried and asked if our girl's patient had not recovered. ”

The old man probably thought that Wan Xue was buying blood on the black market to confirm that it was paired with his own blood, so the old man's idea was not unusual, but it attracted another conjecture between me and Ban Que. Most people go to the black market to buy blood to buy plasma, but it is indeed possible to buy anticoagulant tubes to determine the blood type pairing. And the operator is indeed a doctor in the hospital, and even has a very familiar relationship with Liu Yiyi, Liu Yiyi and Wan Xue are friends, will they also have a relationship with Liu Yiyi? Wan Xue was really sick, and then deceived the doctor's trust on the grounds that Liu Yiyi said that her husband and Wan Xue's blood type seemed to be the same, so that the doctor could find the source of her husband Gong Xiaohuan's blood, and then use the reason for her illness to cover up and get Gong Xiaohuan's blood?

After Ban Que and I had this idea, we found Wan Xue's medical records, and sure enough, as we guessed, Wan Xue was diagnosed with sudden hemophilia a year ago, accompanied by complications from Yan zhòng. We later found Wan Xue in the hospital room, and Wan Xue was not surprised by our arrival. She turned pale and weakly asked us if we wanted to know something about Liu Yiyi and the other deceased.

We nodded and said our conjecture, he didn't refute our guess, but just made some additions, such as his acquaintance with Ou Na, also because of Gong Xiaohuan. Ou Na and Gong Xiaohuan have not been in the company for a long time, and her father is a very important person, and he doesn't even have family photos in his wallet. Naturally, few people knew that she was her father's child. So it is easy for her to hide her identity and avenge her father.

She first figured out Gong Xiaohuan's scumbag preferences, and then became a secret lover with Gong Xiaohuan, and then approached Ou Na as Gong Xiaohuan's underground lover, and then fabricated Gong Xiaohuan's threat to cause uncontrollable consequences, only after winning Ou Na's cleverness, she began to plot with Ou Na to kill Gong Xiaohuan. However, Ou Na can't trust others lightly, and she agrees to kill Lu Qi in exchange. But Ou Na has been forced by Gong Xiaohuan to have no way out, but Gong Xiaohuan has been forcing Ou Na to divorce her husband, so Ou Na very much wants to solve Gong Xiaohuan in person, and for what Lu Qi said to Ou Na's own husband, Ou Na has always been angry, so they reached an agreement soon, Ou Na and Wan Xue killed each other's enemies, and made alibi for each other. It may be that Ou Na can't bear Gong Xiaohuan's persecution, and she doesn't even suspect that he is acting according to the plan. When Wan Xue told the fact that she had framed her father with Lu Qi after seeing Ou Na kill Gong Xiaohuan, Ou Na found out that she had entered the trap that Wan Xue had laid a long time ago. But it's too late, in the face of Wan Xue's threat to him, Oni deserves to choose to obey. (To be continued.) )
