After the analysis and reasoning of the previous paragraph, as well as the self-report of the main suspect, the truth of the hotel homicide case has roughly surfaced, and the only thing that has not been answered is when did Wei Guigui arrive at the hotel? Was it before or after Hong Huijian?

The words before Hong Huijian seemed impossible on the surface, because there was a conflict with the time on the plane. And Yun Yeyao proved that he heard the same person's voice from the time he got on the plane to the time he left the plane.

But let's not forget that before getting on the plane, Yun Yeyao didn't know Wei Guigui at all. So although he can be sure that the person on the plane has always been the same, he can't be sure that the person who got on the plane in the first place is Wei Guigui.

According to the police investigation, Wei Guigui did take the same plane as Yun Yeyao on April 30, and his identity information and so on were his own. Moreover, the surveillance footage of the aircraft door and in the aisle showed that there was indeed a person who was extremely similar to Wei Guigui and got on and off the plane at the right time.

During the entire flight, he did not reappear under the surveillance footage, indicating that he remained in his seat and did not move except to go to the bathroom. But the surveillance footage is not very clear, so the police can't be completely sure if it's the same person.

Mo Haiyou had actually thought of this layer before this, Wei Guigui might use a stand-in to complete the 'task' given to him by Hong Huijian, and in fact, he himself might return to S City in advance to monitor Hong Huijian's actions. It is precisely because of this that Mo Haiyou asked the police to investigate Wei's round-trip trip within 10 days, not on April 30.

The scope of the survey was relaxed to 10 days so that nothing was missed. Wei has a complex relationship, and he is a freelance journalist who often flies back and forth between major cities. To determine whether he used any trickery on the flight schedule, it is necessary to broaden the scope of the investigation.

On the surface, it seems that he is helping Hong Huijian investigate the background of his accomplices and victims, but in fact, no one can guarantee that there is no Hong Huijian among the subjects of his investigation. Besides, finding out the relationship between Bian Benyi and the manager of the Arden Hotel, and guessing that Hong Huijian was going to do something at the Arden Hotel, is not difficult for a reporter who has been wandering among people at all levels all year round to get information for money.

But on that day, that is, the specific time when Hong Huijian killed on April 30, Wei Guigui had no way to determine, let his wife come to the hotel to monitor? This is also unrealistic, maybe if you are not careful, Hong Huijian even killed his wife, Wei Guigui loves his wife very much, so he will never take this kind of risk.

Then the only way is for him to go to the hotel in advance to determine the time of Hong Huijian's move, and leave evidence that he thinks will attract the police.

The police did not find any clues on the flight timetable on April 30, but it was different on April 29, Wei Guigui left S City by plane at 5:30 in the evening, this plane went directly to the city, there was a stop on the way, that is, the stop for refueling, the location was located in the city of S and the city of L in the middle of the city, and the stop time was about 35 minutes.

In those 35 minutes, there was exactly one flight from L to S, which was less than 15 minutes off from the previous plane. And according to the police's investigation of the passengers and surveillance, there was indeed a person on this plane who was very similar to Wei Guigui's figure.

But the identity information he uses is someone else's. Later, when the plane to the city took off again, the surveillance video on the cabin door and aisle did not see anyone similar to Wei Guigui boarding the plane, and the plane arrived in the city and did not see anyone who looked like Wei Guigui leaving the plane.

This shows that it is possible that Wei Guigui did not arrive in the city at all, but returned to S City in the middle of the night on April 29, and the time when the plane returning halfway arrived in S City was more than 9:00 in the morning, and at this time Wei Guigui was completely sure that Hong Huijian had not yet arrived at the Arden Hotel, and he could take his wife directly to the Arden Hotel to ambush and wait for Hong Huijian.

To sum up, it can be inferred that Wei Guigui used a stand-in he knew or hired to take the plane on April 30 instead of himself to complete the task assigned to him by Hong Huijian. In fact, he himself had already returned to S City on the morning of April 30. If they want to prove this fact, the police only need to find the person who sat behind Yun Yeyao in place of Wei Guigui at that time, which does not take much effort, and it will soon be investigated.

If Wei Guigui wants to complete the evidence that he left to the police to expose Hong Huijian's murder, he must grasp the specific time when Hong Huijian killed people in the hotel.

With his means, if the relationship between the hotel manager and Bian Benyi can be investigated, he can completely know the existence of the special nature of room 205, then it is logical to let his wife rent room 204 in advance before Hong Huijian arrives, because room 204 is the easiest to monitor room 205.

At that time, it was very likely that after Fan Xin'er rented room 204, Wei Guigui hid somewhere in the room, and when Hong Huijian entered room 204 to check Fan Xin'er's luggage, he did not carefully check every corner of the entire room, including the bathroom and the bottom of the bed.

Hong Huijian thought that he could use the time period when he infiltrated room 204 to avoid everyone's attention and go directly to the next door to implement the murder plan, in fact, during the entire process of his operation, Wei Guigui in the dark could see it clearly, which is why not long after Hong Huijian finished killing people, Wei Guigui suddenly appeared and took Fan Xin'er to the main station to check out.

As the beginning of the whole murder, although the time of its description is after the murder at the Roquehouse, it has taken enough pen and ink, and after summarizing the final doubts in this chapter, it will not be mentioned in the future.

After cracking the last drug trafficking stronghold of the Midnight Bar and several main suspects have dictated all the facts of the crime, this film will also come to an end. The next reasoning "The Secret of the Treacherous House", which still features Yun Yeyao, Mo Haiyou and Xie Yunmeng, will continue to look forward to your reading. Thank you all for your support so far, and the author would like to express his deep gratitude.
