Among the nineteen waiters, one of the waiters' confession mentioned that he was not supposed to be on duty that night, but an acquaintance came to serve him, and he was called in by name, so he was called temporarily.

Ye Fan looked at the profile photo of the waiter, who was the young man in a down jacket who appeared in the surveillance at the back door at 9:12.

Because he was called on the fly, his name was not on the schedule.

Under normal circumstances, there should be thirty-one people, but there is one person missing, and this person is the cleaner.

However, judging from the surveillance video, during this time, two cleaners appeared, one came out to throw garbage and went back, and the other pushed the cleaning tools back to the cleaning room and never went out at all.

It was a waiter who really left, and it was the male waiter on the computer monitor.

That's the problem.

The two security guards at the back door, their confession was that no suspect was found that night, and the employees who came in and out were familiar with Sheng Hao, and they could prove to each other.

Because there was no difference between the schedule and the actual number of people before, the police did not find this suspicion, and there was no abnormality from the surveillance.

Ye Fan glanced at the time, it was almost early in the morning, she recorded the analysis of the case, and several suspicious photos were also filed and sent to the regular team, and asked him to find the two security guards at the back door that night, the waiter who had passed there temporarily, and two cleaners to ask to see who the cleaner who was missing on the duty schedule was.

After the Chang team sent her the information of the investigation, he had been waiting for her information, and sure enough, he lived up to his expectations, and really let her find the suspicion.

Ye Fan looked at the surveillance of the back door passage again, and this time, it was almost frame by frame, and the dark eyes reflected the dark light of the computer flickering and dimming, which was unfathomable.

The third document sent by the Chang team was an investigation of Xie Qi's information, and the information on his information from within the system was very detailed, and his family background and study and work history were all at a glance.

Xie Qi is three years Chinese New Year's Eve old today, he is a native of the capital, his parents are divorced, he grew up with his grandmother in the countryside of City C, and ten years ago, after his grandmother passed away, he lived alone.

He has good academic performance since he was a child, and various awards are very eye-catching, he does not need to take the college entrance examination, and he is directly escorted to a famous university in country M, and he has been invited by many foreign research institutions and medical systems before graduation.

Six years ago, he had just entered an international scientific research institution for further study, and suddenly, without warning, he gave up the project he had just started, gave up his high-paying job and bright future, ran back to China, turned down all invitations, and became an ordinary clinical professor of medicine at University A, and has since disappeared from the public.

Looking at these materials, Ye Fan really couldn't imagine that Xie Qi, who looked ordinary and was considered unworthy of Lin Yanyan, actually had such a brilliant resume and was such a high-IQ genius.

"Xie Qi's entry record was on August 24 six years ago?" Ye Fan looked at Xie Qi's return date on the data, she had a good memory, and she remembered very clearly that Bai Xingyue's death date was August 23 six years ago, which was the day before he returned to China.

After Xie Qi was escorted abroad, he spent most of his time in country M, but it can be seen from the entry and exit records that he basically returns to China every year, mostly around June.

This time is the time of summer vacation in China, which seems to be normal, but the time in foreign countries is different from that in China, and he took leave at school when he returned to China at this time.

She remembered that Bai Xingyue's birthday was June 8, which was the day he returned to China every year.

To say that this is a coincidence, it is really too much of a coincidence.

The information is all found in the internal system, his information resume from childhood to adulthood, family background, but this kind of official information, in addition to the official spouse, he has made many girl friends, and there is no interpersonal communication, and a deeper investigation is needed.

In the message sent to her, it has been said that it will take a lot of time to find someone to investigate, but because citizens have the right to privacy, it is estimated that it will take a lot of time to investigate if they are not suspects.

One of his hobbies includes sports, basketball, mountain climbing and rock climbing.

It's just that on the list of the Y family, there is no name on it.

Looking at the names of the other six flowers on the list excluding Hong Yi, Ye Fan thoughtfully, picked up his mobile phone, and sent a message to someone on WeChat.

Ye Fan looked through the information and analyzed the suspicious points, the light in the study was continuous all night, and two intimate figures were reflected under the light, busy and warm.

**

The next day, when the Nine Souls of the Dead returned to the Flower Soul World, Ye Fan ordered takeout, left a day's worth of food for Zhu Shengyang, and drove to the police station.

Sheng Hao's two security guards, two cleaners, the temporary worker, and the manager called back to the police station to record a statement.

Ye Fan and Chang Team stood in the observation room, listening to the confessions of the two security guards in the interrogation room, and under detailed questioning, he pointed to everyone who appeared in the surveillance video to identify.

The first cleaner at 6:10, although wearing masks, knew each other well, and they recognized each other at once, and both of them called out the name of the cleaner at the same time.

Ye Fan looked down at a list in the document in his hand, raised his head, his eyes were bright, and he looked at Chang Team and said, "The name of the cleaner he said was on the schedule that night, but it was not one of the two cleaners in the bureau. ”

"That's the one that's missing. Team Chang nodded and instructed one of the officers in the observation room, "Go check the information of this cleaner." ”

The officer took the order and left.

In the interrogation room, in the surveillance video played, the cleaner who went out to throw out the garbage came back ten minutes later, and He Pingfei, who was inquiring, pressed the pause to let the two security guards admit it.

The security guard was strange and said that this was not the one who had just gone out?

He Pingfei got Ye Fan's instructions in his ears and asked them to recall, were they really sure it was her, and what did she say to them before entering the door?

"She's right. ”

He didn't say anything, just raised his hand and signaled, everyone is so familiar that they don't need to check in and out. ”

The two security guards repeatedly confirmed that it was the cleaner who went in and went out.

"Judging from the surveillance, this person came out and went in, and there was no flaw in his walking movements at all, if the person who went in behind him had really become a murderer, this person's ability to imitate disguise was too strong. ”

Team Chang sighed, since Ye Fan told him about the problems he found last night, he looked back and forth with the monitoring no less than ten times, and he really couldn't see that the six people who appeared in the monitoring had any problems.
