However, on the fourth day, there was no so-called fourth deceased, and although it is uncertain whether there will be new deceased in the future, we re-analyzed the case as we watched the case reach a stalemate step by step. The first is the victim, Gong Xiaohuan, Lu Qi and Ou Na, what they have in common is that they all worked in the same company, and they all complained because they framed their predecessors. The relationship between them is also complicated, Ou Na and Lu Qi have maintained an ambiguous relationship with Gong Xiaohuan for a while, and there is no absolute trust between the three of them, and they can even frame each other because of interests, Ou Na is the victim of the struggle between them. After that, the three died one after another, and the number was written in Gong Xiaohuan's blood next to the corpse, coupled with the murderer's excess wound marks on Gong Xiaohuan and Ou Na, it can be judged that the murderer's attitude towards the three people is obviously different. For Gong Xiaohuan and multiple scratches on Ou Na's wrist, it can be seen that the murderer's hatred for the two of them is obviously more than his hatred for Lu Qi.

Pharmaceutical ingredients were found in the stomachs of the three of them, and the residues of sleeping drugs were found in the stomachs of Gong Xiaohuan and Ou Na, and the residues of ****** were found in Lu Qi's stomachs. Therefore, Lu Qi was poisoned with one blow, but Gong Xiaohuan and Ou Na chose to be tortured to death.

Because of the use of drugs, we speculate that the murderer may be a woman, and poisoning is generally the usual method of female killers, because of Henry's restrictions, if the victims who are stronger than them resist, they can easily escape from their control, so female killers will be more accustomed to using drugs to stun the victim and then kill, or directly kill the victim with poison. So we analyzed at the time that the murderer was likely to be a woman.

In addition, because it was used in the homicide case, we speculated that the murderer should have worked in a hospital or a chemical laboratory, because the drug residues detected in the autopsy report, even if they were sleeping pills, were prescription drugs that needed to be prescribed by a doctor. In addition, ****** is a highly toxic drug, except for some companies related to the chemical industry, it is impossible for ordinary people to buy it outside. Based on these two judgments, we speculated that the killer might have been a female employee of a chemical plant, but we also retained the possibility of a hospital worker. After all****** can also be used to euthanasia. So we also speculate that the killer may have come from a veterinary hospital.

Although no suspicious person was seen when Gong Xiaohuan died, it is not ruled out that someone took advantage of the vulnerability of damaged monitoring equipment. But Liu Yiyi, the only suspect Gong Xiaohuan's wife, provided an alibi, and Ou Na also died unexpectedly, and there was no proof of death.

Lu Qi found ****** residue in the honey water she drank leftover. When the honey was tested in the real yàn room, no ****** residue was found in it, so there was no problem with the honey itself and the spoon from which the honey was scooped, so the problem was in the cup containing the honey water. It is a white spherical hard lump, which can be ground into a seat powder, which is very soluble in water, and it is likely that the murderer placed more than 50 mg of ****** powder in the cup that Lu Qi usually uses to drink water in advance, and killed her in the office without even knowing it, and there was no need for an alibi at all.

When poisoned, there will be a brief convulsion, at that time, Lu Qi did hear the sound of Lu Qi's office at the same time, because the sound appeared very short, so the surrounding colleagues thought that she was losing her temper as usual, so they retreated from his office, trying not to get close, knowing that the new colleague ventured in to deliver information with the determination to die, only to find that Lu Qi died.

We checked the photos of Lu Qi's death scene and found that there were many cups in his office, and he seemed to be a cup collector, but according to the inspection of the police personnel, except for the reason for the cup containing honey water ****** the residue of ingredients, the poison test of other cups was negative, which means that the murderer only added ****** to that cup. However, in the repeated questioning by the police, an employee who has worked in the company for a long time revealed that although Lu Qi has a habit of collecting cups, Lu Qi has always used a health cup that is not very good-looking. It is said that it is because Lu Qi stubbornly believes that the inside of the cup that has been used for a long time has been washed out for a long time, so the toxic substances in the cup material have disappeared and can be used with peace of mind. Even though someone had reminded her that her theory was completely unfounded, Lu Qi still used the old cup as she should. However, when talking about customers, Lu Qi often uses those beautiful cups to show her taste, so most of the trusted employees don't know such things, and Lu Qi often sits in her office, so it is difficult for ordinary employees to see her usual appearance.

The old employee also told the police who went to investigate that Lu Qi usually cherishes his life and pays great attention to health, and even the honey he often eats goes to the countryside to buy it in person. In this way, the murderer is a person who knows Lu Qi very well, and even knows that he can't frame the person who sells honey to escape the police's suspicion of himself. The murderer knows Lu Qi's situation well, but he can avoid the suspicion of others, this person should not be an employee of Lu Qi's company, at least not a rookie in the workplace who knows nothing. But if it weren't for the employee of this company, his appearance in Lu Qi's office would definitely be particularly noticeable, after all, Lu Qi is a rather high-profile store in the company, her daily life is in plain sight, if a little unfamiliar factor appears on the scene, it will definitely be impressive.

Ouna, who died in the bathtub, thought Nei had been murdered in her own home, and the only person with the keys to her house and the motive for the crime was ruled out.

The numbers that appear next to the three people represent the order of death of the three people, and the three numbers are all written by Gong Xiaohuan's blood, which means that the murderer either drew Gong Xiaohuan's blood when he died, or Gong Xiaohuan's blood was already retained. Ban Que and I were more inclined to have it already preserved, because no traces of talent were found on Gong Xiaohuan's body, and if blood was collected at the time of assassination, traces of collection tools would also be left at the scene or on the corpse, but there were no such traces in the photos taken by the investigators, and the forensic doctor did not find any corpse spots caused by the collection tools staying on the corpse during the autopsy. So before Gong Xiaohuan was killed, he provided the murderer with his own blood sample for some reason.

After combing through the situation of the three victims, we roughly profiled the murderer. The murderer has a relationship with these three people, and the relationship is very close, he can make an appointment with Gong Xiaohuan to the hotel, and he can enter and leave Lu Qi's office at will without arousing suspicion, could this person be an old employee in the company? Ban Que denied my idea at the time, combined with the clues provided by the drunken staff and the old employee, because of Lu Qi and Gong Xiaohuan's unorthodox behavior before and Lu Qi's later unreasonable domineering, almost no one in the company was close to them. Especially Lu Qi, no one will know his living habits at all, and if there is ****** residue in each cup, it is still possible to infer that it is someone in the company. But only the ****** residue appeared in the cup she often used, which shows that the murderer is a person who knows Lu Qi very well.

When we said this, the two of us had an idea at that time, except for the fact that it appeared in Lu Qi's office, which did not meet the clues provided by the old employees, the other candidates who met the conditions turned out to be the third question about the deceased Ou Na. Because of the previous intimate relationship, Gong Xiaohuan can be smoothly crossed to the express hotel that he is familiar with, and only Ou Na is the only one who has gotten along with Lu Qi and knows enough about his living habits. Coupled with the fact that she was out of the internal struggle of the small group before, and because she was caught by Lu Qi to guide her own marriage breakdown, Ou Na's hatred for these two people is obvious. Especially for Gong Xiaohuan, Ou Na tried to win him over wholeheartedly, but was betrayed by the backwater in the end, this hatred is obviously greater than the anger of being kicked out because of insufficient strength, so Ou Na can definitely do something to assassinate Gong Xiaohuan several times to relieve his anger.

The motive is found, and the next thing we solve is the mystery of how O Na entered Lu Qi's office.

We were puzzled as to how O Na was able to enter Lu Qi's office without anyone else knowing. At first, we were puzzled, but then it was a special coincidence that the day of Changsheng's question happened to be the 100th anniversary of my relationship with Ban Que, when the gift I ordered online happened to be delivered to my home by the courier, and the two of us figured out the previous question at once. (When I said this, I could ignore the question that Li Jing had been trying to interrupt and ask if I was living with Ban Que at the time)

After the postman left, I pointed to Ban Que to the package that had been delivered, and then to the direction in which the postman had left, and Ban Que also understood my thoughts. I think it's possible that O Na entered Lu Qi's office posing as a courier. Ban Que found the drunk employee who knew about the situation again, probably because after Ban Que laughed drunk again last time, he helped the little brother arrange a place to stay, and paid the room fee for him in advance, and left him an antidote medicine by the way, the little brother had a very good impression of Ban Que, and when he heard that Ban Que lied to him that he would soon join the company, Ban Que thought twice according to his authority. Banque knocked on the side and asked some questions about whether the company can receive express delivery, and the result is that the express delivery is generally issued after receiving it by the company's front desk, because the company has more people, if it is too frequent to receive express delivery, it will cause the complaint of the little girl at the front desk, so the general staff is rarely express mail to the company. However, for the company's senior management, the front desk is happy to help send and receive express mail, and personally hand it over to these bosses. However, for those large items that are difficult to carry, the little girl at the front desk will accompany the courier to deliver the package to the manager's office.

After getting the courier allowed to enter and leave the office, Banque confirmed my suspicions even more. After that, he didn't bring up the topic again, until the company employee was drunk again and couldn't control his own thoughts, and Ban Que began to ask him in detail about Lu Qi. But at first, I just pretended to be curious about the case. It may be that after drinking, he couldn't control his thoughts, and the little brother soon began to babble and abuse their Manager Lu, and it can be seen that for this Manager Lu, ordinary employees really don't have a good impression of him, and suddenly mentioned the situation on the day she was murdered.

On the day of Lu Qi's death, he received a very large package, and the delivery of the package coincided with Lu Qi's morning meeting for some project employees, their company went to work at 9 o'clock, and the regular meeting generally started at 9:15, and the duration ranged from a quarter of an hour to half an hour, and the courier arrived at the office front desk at 9:20 in the morning. It happened to be stuck at the beginning of the morning meeting, the package was very large, and it looked very heavy, it was difficult for the little girl at the front desk to carry it alone, but no one at the front desk girl was even willing to help her send the courier into Lu Qi's office, although she would not be scolded directly, but she was afraid of being reprimanded for suddenly asking about work, so few people were willing to go to her office. But the little girl knew that if she suddenly appeared in the back office and disturbed the morning meeting, Hermes would be indispensable, so she played a trick and gave the courier a general direction, and let the courier send it in by herself.

When Lu Qi had a meeting, he saw the courier going in and out of the office alone and was about to get angry, but the courier asked Lu Qi where his office was. I continue to hold meetings with my employees. Originally, everyone was still secretly praying for the little girl to be scolded very miserably in the future (after all, let the person with the worst temper in the company show himself in public), but more than an hour later, the news of Manager Lu's death came out. However, it felt that everyone was not sorry after hearing the news of her death, but breathed a long sigh of relief, secretly glad that she was finally free from the subsequent devil's sanction.

After dealing with the oldest company employee again, Ban Que came back and confirmed our speculation with me, that Erna was probably pretending to be a courier staff and sneaking into Lu Qi's office to put ****** into Lu Qi's health cup. She knew that Lu Qi would have a regular morning meeting, and she also knew that Lu Qi would treat it differently when she learned that it was her own fast, and let the courier send it directly to her office, and she also knew that Lu Qi would not hesitate to accept it even if she was not sure whether the courier was her own. There was no further confirmation at all, so she first stated her intentions and then entered Lu Qi's office to find an opportunity to poison her. As for the voice, it was not in ancient societies, pre-recording, or using the voice change period, there were too many electronic devices capable of constructing a woman's voice to transform into a man. As long as you enter Lu Qi's office, the plan behind can be implemented smoothly. (To be continued.) )
