Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 517 Finding Evidence
Zhang Hui saw the chilled wild puffer fish that Liang Yuancheng talked about in the back kitchen of the hotel.

They are indeed pufferfish that have been skinned and their internal organs removed.

"Comrade police, if you don't believe it, I can eat it right now and show you. There is absolutely no toxin left in this food."

Inside the hotel, there are several live puffer fish in the display window at the entrance. According to Liang Yuancheng, they are all farmed puffer fish, which is usually what guests eat when they come.

Only some regular customers come here to order chilled wild puffer fish.

But even those old customers will not see the original appearance of these chilled pufferfish. They are all prepared directly by the kitchen and served.

Zhang Hui checked the hotel's purchase and shipment records.

How many items have been purchased, how many items have been sold, and how many items are left, the recent shipment and purchase records can be matched.

After leaving Hao and coming back to Huaiyang Cuisine Restaurant, Zhang Hui knew that this clue was basically broken.

According to Liang Yuancheng, he is the only place in Haizhou City that sells chilled wild puffer fish.

There is no live or chilled food anywhere else.

The reason why Liang Yuancheng was able to get this kind of puffer fish is because one of his cousins ​​in the production area is a chef who specializes in puffer fish slaughtering.

So there will be some quota for him there.

After all, this thing can't be caught at any time, and the quantity is not very large.

Moreover, the method of fishing for wild puffer fish is also quite special. It is impossible to touch it directly with human hands using ordinary fishing methods. In that case, you will just wait to die.

While Zhang Hui found nothing, Sun Jun's side was just the opposite, and great progress was made in the detection of the case.

The old man who jumped to his death at a construction site a month ago was named Zhang Guicheng, and his son, who had leukemia, was named Zhang Guojun.

The clue that led to a major turning point in the case was Sun Jun's discovery that Zhang Guojun entered the construction site half a month ago and worked as a laborer tying steel bars.

Zhang Guojun has been diagnosed with leukemia and has only a few days to live. How could he still come to the construction site to work?

And I think of Zhang Guojun's father jumping to his death at the construction site a month ago...

The possibility of Zhang Guojun retaliating and poisoning is... very high!
In the northwest corner of the construction site, Sun Jun saw Zhang Guojun who was tying steel bars.

Zhang Guojun is not tall, only about 1 meters tall. He is very thin and pale. At first glance, he looks unhealthy.

"Zhang Guojun?"

Zhang Guojun didn't look back and just kept tying the steel bars.

Sun Jun thought that the other party did not hear his voice, so he took a step forward and made his voice louder.

"Zhang Guojun?"

"Well, I heard you."

Zhang Guojun's voice was weak and hoarse. He stopped what he was doing and took off his gloves: "You are a policeman, right?"

"You know me?"

Zhang Guojun shook his head: "I don't know you. I heard from my coworkers that the police are investigating food poisoning."

"what can I do for you?"

Sun Jun nodded: "My name is Sun Jun, I am a criminal police officer from the Criminal Investigation Detachment. I came to you to ask you to cooperate in the investigation of food poisoning in the canteen at the construction site."

Zhang Guojun seemed to be tired of tying steel bars. He sat on the pile of steel bars on the ground, took out a cigarette from his jacket pocket and lit it.

cough cough.

Perhaps it was because he had smoked too hard, Zhang Guojun coughed violently, and his face became paler.

"I have nothing to say about this matter. I also ate there in the morning, but luckily I didn't drink vegetable soup, so I'm fine."

Sun Jun's expression suddenly changed.

If he had come to see Zhang Guojun just now because he suspected that Zhang Guojun was poisoning in revenge for his father's death, now, this suspicion is confirmed.

Because no one has ever said that only vegetable soup is poisonous, but steamed buns are not poisonous.

This was the result that Lu Chuan discovered this afternoon when he was doing a test at the Criminal Investigation Detachment.

But why did Zhang Guojun say that he was not poisoned because he didn't drink the vegetable soup? How did he know that the vegetable soup was poisonous but the steamed buns were not? "Zhang Guojun, how do you know that only vegetable soup is poisonous?"

Zhang Guojun was stunned for a moment, his expression changed, and then he pretended to be nonchalant: "Oh, I guessed it."

Guess what?

"Zhang Guojun, you were the one who poisoned the canteen, right?"

"I?"

Zhang Guojun wiped out the cigarette butt that had burned to the butt of the cigarette: "Comrade police, you are most concerned with evidence when handling cases. If there is no evidence, you will accuse me of poisoning?"

"evidence?"

"Zhang Guojun, if I say that I was only suspicious of you, but after you revealed the poisonous information in the vegetable soup, it proved that you are definitely the murderer."

"I just made a guess. Just a random guess...can't be considered a crime."

"Okay, comrade police, if you have evidence, you can take me away. If you don't have evidence, I will still have to work."

After Zhang Guojun finished speaking, he stood up and tied the steel bars, ignoring Sun Jun's inquiry.

"You guys are watching here."

After Sun Jun spoke to the two detectives behind him, he turned and left.

Now it can basically be determined that Zhang Guojun is the real culprit of the poisoning.

First, in terms of the motive for committing the crime, it is reasonable that his father died at the construction site a month ago and Zhang Guojun poisoned him in retaliation.

Secondly, Zhang Guojun himself suffers from blood cancer, and it is still in the advanced stage. He has not much life left. To him, even if he is sentenced to death for poisoning and killing, the probability is that it will not matter.

The third thing is what Zhang Guojun accidentally let slip just now, about the poison in the vegetable soup.

The entire construction site didn't know what kind of food in the canteen caused the poisoning?

They didn't even know what they were poisoned with.

Why did Zhang Guojun know that the vegetable soup was poisonous?

This is not something he can just guess with a casual guess.

But even if it can be confirmed that Zhang Guojun is the poisoning suspect, Zhang Guojun is right, where is the evidence?

There was no surveillance room in the canteen where the incident occurred, and no one else saw Zhang Guojun poisoning. There was no surveillance, no video, and no witnesses.

Where is the evidence to arrest Zhang Guojun?

Criminal investigation detachment meeting room.

Sun Jun is reporting on the investigation.

"Judging from the current clues, Zhang Guojun is suspected of committing a major crime, but there were no witnesses during his poisoning. There is no evidence to prove that he poisoned. There is insufficient evidence for his arrest now."

"I have sent two brothers from my team over there to keep an eye on him. He will definitely not be able to escape."

"The key now is to find evidence that he poisoned."

Zhang Hui followed Sun Jun's words: "I have checked here and found that there is only one Huaiyang restaurant selling wild puffer fish in Haizhou City, and the wild puffer fish they sell has been processed in the place of origin and has no toxins. Came here."

"In addition, Lu Chuan found some pufferfish skins and remnants of internal organs in the vegetable soup. This means that when poisoning, the other party should have thrown part of the wild pufferfish directly into the vegetable soup, thus causing food poisoning. .”

"From this logic, as long as we find Zhang Guojun, how can we get the evidence of wild puffer fish to convict him."

Everyone listened and nodded.

It is true that no one saw the poisoning process by Zhang Guojun, and no evidence can be found in this regard. Logically speaking, as long as it is proved that Zhang Guojun had pufferfish poison, it can be proved that he did the poisoning.

As for how to find tetrodotoxin in Zhang Guojun's hands, it is relatively simple.

Zhang Guojun's father died a month ago, and Zhang Guojun's poisoning was directly related to his father's death.

So as long as we figure out Zhang Guojun's itinerary one month after his father's death, we can probably find evidence of how he obtained the wild puffer fish.
