Manager Wang transferred the surveillance very quickly. Within ten minutes, he called Jiang He and asked him to take Tang Huanxi and others to the surveillance room.
The monitor in the monitoring room showed the deceased’s activities in the hotel at different times.
According to Manager Wang, the deceased was a side dish cook in the kitchen. Because he received a call from Jiang He at noon, he arrived at the hotel at around two o'clock.
During this period, he worked in the kitchen almost all the time, and the video was also recorded. He only went out a few times, always to the toilet.
While going to the toilet, I didn't come into contact with anyone.
Except for the chefs in the kitchen, these chefs have been controlled by Jiang He's people and are being interrogated.
Therefore, it is still extremely difficult to obtain some information from surveillance videos.
"Uncle Ma, can you deduce the approximate time of poisoning from the time of death of the deceased?"
Tang Huanxi frowned and stared at the surveillance camera, then suddenly turned around and asked.
Ma Wenqing pondered for a moment, then looked at his watch: "It is now half past eight in the evening. Judging from the vomit I found in the deceased's mouth, the onset time of this medicine should be about three hours."
"In other words, around five o'clock in the afternoon was the time when the deceased was poisoned."
"Adjust the video to 4:30 and watch 6:00 at 10x speed. Quick."
Tang Huanxi's tone was urgent. She now knew very well that time was life. If the source of the poisoning and the poisoner were found a second earlier, there would be more hope for the lives of thousands of employees on the site.
Soon, the staff quickly played back the video, fixed the starting time at 4:30, and played it at ten times speed.
"stop!"
At 4:58, Tang Huanxi suddenly stopped.
At this time, the deceased in the picture had just walked out of the bathroom, walked quickly through the passage, and walked into the kitchen.
"Go back and freeze it when he first came out."
Tang Huanxi spoke.
"good."
When the staff called back frame by frame and fixed the scene in the men's bathroom when the figure of the deceased had just appeared, Tang Huanxi suddenly pointed his finger at his face:
"If I remember correctly, after he left the bathroom this time, no one used the bathroom at the back, and no one came in or out."
"But if you look at his face when he came out, he looked back and looked uncertain when he went out. There must have been other people in the bathroom at that time, but this person never left through the front door."
Under everyone's shocked gazes, Tang Huanxi said in a deep voice: "Exactly three and a half hours, the bathroom, the invisible stranger, and this person's sudden death..."
"I suspect that he was the one who poisoned the kitchen, but for some unknown reason, he accidentally came into contact with the poison and died prematurely."
"Switch the surveillance video to the morning, 20 times the speed, from the morning until before he enters the bathroom."
"During this period, someone must have gone in and never come out again."
As she said that, she looked at Zhang Zihao: "Now in Nandu, Bai Qiming and the others need to be responsible for guarding the research room. They can only rely on you here."
Zhang Zihao understood, nodded, stopped talking, turned around and rushed out.
At the same time, a figure slowly emerged from the surveillance video, attracting everyone's attention.
A middle-aged man.
"It's him, it's him!"
"The leader of the Ma Family Poison Hall, Ma Wenfeng!"
After seeing this person, Ma Wenqing and his wife screamed out in shock.
