According to Tang Donger's and Tang Jishui's descriptions, we basically learned that the number of participants in these two family gatherings was about ten people, and everyone ate and drank together, and there was nothing special about it. However, after the party, it happened that some people were fine, while the other part had stomach pain, vomiting, and feeling sick!

"This part of the people has had a conflict with Jixing? In other words, the target chosen for poisoning is targeted? I touched my chin and began to think about the crux of the matter.

At the same time, Xu Jiaqi and Tang Lin had already turned on their respective computers, one began to describe the scene at that time according to Tang Donger's description, and the other began to sort out and analyze various key points.

Now let's review these two poisoning cases. First, seven days ago, Wang Xiaomei celebrated her 40th birthday and had dinner with a few friends at home, and then everyone stayed to play cards and chat. After that, everyone dispersed, and that night, one group of people had symptoms such as vomiting and stomach pain.

The second was a family gathering of Tang Zhong'an four days ago. After everyone had dinner, Tang Zhongan and some people drank tea and chatted with people in the private room of the family restaurant he opened. At the end of the meeting, some people also experienced vomiting and stomach pain.

"In these two poisoning cases, did anyone go to the hospital to check and find out what kind of poison they were in?"

Tang Donger shook his head and said: "Because the poisoning is only for a moment, and the people in the village are generally reluctant to go to the hospital for minor illnesses and disasters, at most, they will take an injection and take a medicine in the village clinic, drop a water, and everyone will no longer have symptoms the next day, so there is no specific investigation, why is there nothing going on?" ”

Tang Sen said: "According to your description just now, the few people who were poisoned basically showed symptoms after returning home, so at this time, they didn't know that there were other people who were poisoned." It is almost impossible for a group hysteria to exist. Could it be that they are lying? ”

"It's not a lie, most of them have symptoms, and their families have confirmed that they are indeed uncomfortable." Tang Donger added.

That's weird. Everyone dispersed, and in the absence of continued intersection, how could there be a large-scale collective hysteria? Isn't it collective hysteria? It's really poisoning!

"In the two poisoning cases, did they collectively come into contact with anything?"

"Except for eating and drinking, you don't see any problems?"

Townsend looked at me, wondering what I was thinking. And at this time, how else can you think about it? Leaving aside the ghosts that can't be explained, the only thing that can be explained is the food and what they have drunk. It's just that they eat and drink together, why do some people have stomach aches and others are fine?

Xu Jiaqi pondered: "Could it be that someone is poisoning in a targeted manner, for example, putting drugs that cause abdominal pain in the cups of some specific people?" ”

"It's also less likely, because I've learned that what they eat and drink is not prepared separately. Even the teacups and rice bowls are put together, and everyone chooses them at will before eating and drinking! ”

Wang Xiaomei's birthday party, under normal circumstances, it is naturally impossible to leave surveillance pictures at home, and we can only rely on some mobile phone videos and photos taken by everyone at that time to provide judgment.

I asked everyone to immediately collect all the videos, photos or materials about these two poisoning cases, and Tang Jishui also asked Tang Minyun to assist us as agreed, and soon got some useful information.

Thankfully, Tang Zhong'an's hotel box did have a surveillance camera, but as soon as this picture was released, we were completely blind. First of all, the picture of the box was not clear, and secondly, because there were more people at that time, we couldn't distinguish the behavior of some people, so I could only completely hand over this video to Xu Jiaqi and let him do the picture processing.

Until the next day, we were still having a headache for those poor videos and photos, Xu Jiaqi and Tang Lin worked together, and it was so hard that they analyzed the box picture frame by frame.

From the hotel where we stayed, we could hear the noise outside. As Tang Yi said, if this matter is not immediately concluded, this Tangjia Village can really turn the sky upside down.

We specially rented a small conference room in the hotel, and everyone has been immersed in the analysis. Tang Minyun, a female policeman, couldn't help much, so she could only serve us tea and water and buy some snacks. When I thought that the servant of the people had finally become a servant of the people, this time, hey, let's help the servant figure this matter out.

We've watched these videos dozens of times, and to be honest, we really can't find anything to do, but what else can we do? If you had to get everyone in two meetings to come in and interview them individually, it would be a lot of work. Moreover, what should be asked, in fact, Tang Minyun and other policemen have also helped us ask, these records, can help us, there is no for the time being!

The bored Xie Lei was already yawning, even Tang Minyun couldn't support it, holding his head, his face expressionless, from morning to three o'clock in the afternoon, we have been watching repeatedly, the question, where is it?

The food is eaten and the water is drunk, and through the video and introduction, even the container is not specially prepared for some people, so if someone is poisoned, where will it start?

Tick-tock, the clock is reminding us of the passage of time。。。。。

"Linlin!"

"Uh, what's wrong?" Tang Lin suddenly looked back at me, I don't know why I broke the silence!

"You take the picture of pouring water just now, zoom in, slow down, and put it aside!" I had risen from my seat, and Townsend followed me to the front of the screen.

Tang Lin didn't know what to do, but she still did what I instructed. Each of them stared at the hand of the person who poured the water, trying to see if she had put something into the glass, but, after looking at it countless times, the waitress had not put anything in it at all.

"What do you think of?" A smile suddenly appeared at the corner of Tang Sen's mouth.

I understand that he has already seen the problem: "It is indeed artificial, and it is relatively intelligent, but this is not the first time that such a method has appeared!" Somewhere, she must have learned it! ”

"Hey, what the hell are you two talking about?" Xu Jiaqi opened her mouth puzzled.

Tang Minyun also rubbed his eyes and said, "Do you know how you committed the crime?" ”

Townsend and I pointed to the person in the video at the same time, and one by one, "Bring this person here." ”

"At the same time, bring up this person's information!"

Everyone was staring at the scene, and none of them understood what was going on, except for me and Townsend.

What Tang Sen and I were referring to was the waitress who poured water, but she really didn't have any extra movements!

"You two, could you be mistaken about something?" Xu Jiaqi's eyes widened vigorously, wanting to see if she had missed it. It's just that she did not miss it, but the people in this room were deceived by appearances!
