Ou Na invited Gong Xiaohuan to the theme room of the hotel, which was in trial operation, and he knew that Gong Xiaohuan was a member, so he specially asked him to book the room on the fourth floor. Later, as we speculated, the fourth floor of surveillance equipment was destroyed. As for why he chose the fourth floor, Ban Que thought that it was in a state of trial operation, and there would be very few guests on the fourth floor, and Ou Na would not be seen when she retreated; Moreover, members can only make appointments in person, so it is not easy for the police to find out the identity of another guest when the police investigate. Later, on the day of the crime, Ou Na did not enter from the hotel gate to the 4th floor according to the normal distance, but entered the hotel through the back door after dressing up in disguise. Because the hotel is her client, Onia knows all the surveillance cameras, and she is able to get past the surveillance and enter the staff lounge area.

He knows this hotel, he knows the time of the night shift here, after the peak period of stay, she knows this hotel, and can even dress up as a hotel service staff or maintenance staff to enter the hotel through the back door, and enter the fourth floor through the secret passage of the staff rest area, even if it is seen, it will be considered a service staff, and will not be suspected by others. After that, as long as Gong Xiaohuan can take sleeping drugs, he can assassinate Gong Xiaohuan when Gong Xiaohuan is powerless to resist or even call for help. Gong Xiaohuan was too confident that he could control Ou Na with his handle, but he didn't know that Ou Na had already planned to kill him, and then after a revenge like venting his anger, Gong Xiaohuan died of blood loss. Because of the divorce by agreement, no one will care if she returns home, and Ona has plenty of time to deal with the scene, including cleaning up any traces she may have left on the scene without destroying it.

But those are just our speculations, the motive and modus operandi have been clear, but we still have no clue how Erna got the auxiliary drugs used in the crime. Even if you can get a prescription to buy sleeping drugs. However****** this is not available on the market, we have checked Ou Na's family, whether it is her family or she herself has nothing to do with the hospital, to be honest, we even checked the pet hospital, and still did not find any connection. To tell you the truth, we even went to the underground black market at that time to inquire about any recent ****** and buyers' information, but what we got still had nothing to do with the case. Ona hasn't been to the black market.

When Li Jing heard me say this, he shook his head and asked me if I had neglected some special circumstances.

I nodded and admitted that we had made a mistake at the time, that we had ignored the surroundings around Ona. So after we re-combed through the information of the two people's mobile phones, we even felt for a moment that our previous speculations were wrong. You know I'm not a particularly optimistic person, but Ban Que is, and Ban Que's character is the kind of persistence that doesn't hit the south wall and doesn't look back, sometimes even if he hits the south wall, he still won't look back, until he hits it. Anyway, he has confidence in his own judgment. So although I have been wondering if the two of us are wrong, Ban Que is convinced that he is right, and he no longer focuses on the source of the medicine, but goes to explore the truth about Ona's death. And I, because of those unsolved mysteries, are here to investigate separately from Banque.

Like you said, I always felt that I had missed some particularly important details, since her relatives did not work in the hospital or in the real room, but we ignored the purpose of Erna to kill - revenge because we pursued her access to medicine too much. If we see this purpose clearly, it is easy to find another group that we ignore, people who are dissatisfied with Gong Xiaohuan and Lu Qi like Ou Na, and those company seniors who were framed by them.

I later checked the company's resignation records from three years before the case to the time of the case, and the company they joined later, and finally let me find out another thing that has puzzled us for a long time, why Liu Yiyi's car appeared in the community where Ou Na lived on the day of O'Na's death.

Aggressiveness may really force people to death, and that case made me really understand this sentence. That's right, Liu Yiyi lent the car to Wan Xue, but if you know the intricate relationship between Liu Yiyi, Wan Xue, and Ou Na, as well as the countless coincidences between them, you will find that the phrase 'no coincidence makes no book' is really not a joke.

It is true that Wan Xue and Liu Yiyi are friends, they are considered to have a small relationship, and Liu Yiyi has enough motives to cause Ou Na to die, and even Liu Yiyi has a motive to kill Lu Qi, but when these two people had an accident, Liu Yiyi had a clear alibi, but when Ou Na died, Liu Yiyi's alibi was also used to prevaricate the investigation with medical treatment like Ou Na. While there is evidence that seems as indestructible as medical records, on closer scrutiny, it is a flawed piece of evidence. The medical insurance card can prove that Liu Yiyi was not at the scene, and the medical insurance card can also prove that Liu Yiyi was at the first scene of Ou Na's death.

You know, this kind of small card that can be logged in and leave traces as long as it is put on the machine, in fact, does not prove that Liu Yiyi went to the hospital that day, after all, as long as the gender is the same and the age is similar, it is very simple to impersonate. So it's not an infallible piece of evidence, and the rest of the speculation is logical after overturning this evidence.

However, there is still a question, that is, why did Wan Xue help Liu Yiyi, even if the relationship was good, it would not be good enough to help him kill people. But if Liu Yiyi wants to kill Ou Na, there is only one way to get through Guò Wan Xue, so Wan Xue is the key to the whole case. This is also why I had no experience at all when I found out that Wan Xue's name appeared among Ou Na's relatives, and I even had a feeling of being stunned.

Wan Xue herself has no direct relationship with Ou Na, but Wan Xue's father has a very special relationship with Ou Na. I don't mean the relationship between Ou Na and Wan Xue like the intimate relationship between Ou Na and Gong Xiaohuan, on the contrary, at the beginning, it can be said that the relationship between Wan Xue's father and Ou Na is extremely bad.

Wan Xue's father is a senior of the company who was once suppressed by Lu Qi, and Wan Xue's father did not find a new job smoothly after leaving the company, to be precise, Wan Xue's father was taken away by the police. I checked that Wan Xue's father was accused of stealing company secrets, and was called to the police by the company for leaking the company's information during the bidding. After that, all the unfavorable evidence pointed to Wan Xue's father, and the end was that Wan Xue's father was sued by the company, not only in prison for two years, but also compensated the company a large amount of money. I checked the time when Wan Xue's father was sued, and found that it was when the clerk and Ban Que said that Lu Qi's trio were like fish in water, and Wan Xue's father was an old-timer who had taken Lu Qi, and Lu Qi and Ou Na were also involved in the bidding of that project at that time, and when the accident finally happened, the two of them did not receive any suspicion. According to reason, if there is a problem with envy, it must be that everyone in charge of the project is responsible, just how much is responsible, but in the end, only Wan Xue's father was prosecuted for that project, and in the evidence provided by the company, Lu Qi and Ou Na were both witnesses, according to the information collected by Ban Que before, Lu Qi and Wan Xue are definitely trying to protect themselves, not only to join forces (although their previous state was also joint) to commit perjury, but also to frame what they did to Wan Xue's father, Later, I asked someone to check the court records at that time, and found that in the court, Wan Xue's father had always denied that he had never contacted competitors or provided them with any company information. But the other party insisted on the information bought from Wan Xue's father, and finally thought that Wan Xue's father lacked evidence to prove his innocence, and was sentenced to prison. After that, Wan Xue's father died of illness in prison before he could be released from prison due to physical reasons.

In this case, it makes sense to avenge his father and unite with Liu Yiyi to kill people. And when I found Wan Xue, Wan Xue herself worked in an electronic precision instrument company, and one of the uses of ****** you know is etching, and now in the semiconductor process, time is an indispensable technology. It's very convenient to get a little ****** in their company. A ****** of 50 milligrams to 100 milligrams can kill someone, and even by taking a little bit at a time, Wan Xue can take the ****** she needs out of the company without being noticed.

As for sleeping drugs, after Wan Xue's father died in prison, Wan Xue's mother suffered a mental blow because of the blow, and she needed sleeping drugs every day to fall asleep, and taking a few tablets from her mother's medicine could make people fall into a deep sleep. Although on the surface it seems that Wan Xue is the most suspicious, but I have found out that when several victims died, Wan Xue seems to have deliberately made an alibi for herself, since the day of Gong Xiaohuan's death, Wan Xue can't wait to appear in the crowd every day, Tong Guò was photographed by surveillance, to attend various activities, Wan Xue has created countless alibi for herself.

Although he knew that he was suspicious, he could not find any evidence that could refute it. But the auxiliary medicine is in her hands, and it is impossible for him not to have a connection with the case. So I took the clues I found and did a second analysis with Ban Que.

Ban Que was excited when he saw me, and he said that although he had not found the source of the medicine, he already knew who had killed Ou Na and how he had done so. And I brought her the answer about the drug.

Ban Que is the kind of person who is very passionate, and there are many differences from me before, he will first make wild conjectures, and then verify his own conjectures, although he will always be verified for the errors of the conjectures, but he can find a lot of useful information in the verification process that we have ignored before. But even if he is slapped in the face by reality, he will insist on the correctness of his conjecture. "In terms of conceit, he is better than you." Speaking of which, I looked at Li Jing and joked, "You are very similar in personality, maybe that's why I felt that you were familiar from the beginning." ”

Li Jing don't overdo it, I know this sentence hurts his self-esteem.

"But he died of his own conceit in the end, so I hope you can break this habit and live well." I shook Li Jing's arm slightly, "I have never treated you as a class, although you two are equally conceited and annoying, but you are still different from her, you have never been him." Whether it is in my right heart or in my heart to restore my memory, you are a different kind of existence, like walking a long night road, and when you are lost, you see the dawn sun, which makes me feel that my whole life is full of hope again. So I hope you can live a long and healthy life, and you can save a lot of people, both lives and hearts. ”

"What do you mean?" Li Jing's expression suddenly became nervous.

I stretched for a moment before saying, "It's not interesting, I just hope you can get rid of your character stinky faults, stop making the same mistakes as Ban Que again, and don't ruin your good life like my boyfriend." Okay, I'll move on to the story of the year. ”

However, this time the conceit helped us a lot, although he did not find direct evidence, he analyzed what might have happened after Ou Na's death eat. He didn't name the suspect, but said that the murderer was someone that Ou Na trusted very much, and that Ou Na was in a state of anxiety after the murder, and the wind and grass would make her panic like a frightened bird. The person she could meet at this time must be someone he trusted very much, so Banque speculated that this person was most likely her accomplice. Even if she didn't want to meet the accomplice, she was probably influenced by some special factor, or threatened, so he had to let the murderer into his room. But Ou Na has always been wary of this murderer, so that she has not been able to succeed, the murderer finally used Ou Na's method of killing Gong Xiaohuan, first biting down Ou Na, and then dragging Ou Na into the bathtub, probably because he was afraid that Ou Na's potential survival consciousness could not completely kill Ou Na, and finally cut Ou Na's wrist, so that Ou Na died of blood loss.

There is also a situation that the murderer first killed Gong Xiaohuan and Lu Qi under the pretense of Ou Na's hand, and then killed Ou Na in the same way, in view of the murderer's appearance of cutting Ou Na several times, Ban Que judged that he may be full of hatred for the previous two victims like Ou Na, and even full of hatred for Ou Na herself. And the murderer used sleeping pills again, which shows that Ou Na's currency is also a woman, and the murderer's body shape should be similar to Ou Na, or even thinner than Ou Na, so that she can be full of unconfidence in the direct assassination of Ou Na, so she understands Ou Na's life in combination with drugs.

And he has a disagreement with Ou Na in his analysis, he can take Ou Na's life by drowning after killing several times, and Liu Yiyi is the only one who is suspected of this and can do such a ferocious method. (To be continued.) )
