After finishing the transcript, Han Bin returned to the meeting room.

Tian Li, Li Hui, and Sun Xiaopeng compare the dishes eaten by the poisoned and non-poisoned guests, and classify and sort them.

Han Bin sits and drinks tea. This is the advantage of being a leader. When he wants to do it, he will do it, and when he doesn't want to do it, he will move his lips and tell others to do it.

After Han Bin drank a cup of hot tea, Tian Li and the three also finished sorting it out.

Li Hui stretched his waist and said, "Oh, so many delicious foods make me hungry."

"Team Zheng called just now and a poisoned person was not rescued." Han Bin said.

Li Hui "..."

"Cough..." Zhao Ming coughed lightly: "I've decided. I will eat instant noodles at noon today."

Han Bin didn't mind joking, and asked, "How is your investigation?"

Tian Li handed the document of her classification to Han Bin, who was sitting in front, and said: "According to our sorting out, almost all the poisoned people have eaten dishes with beef; and those who are not poisoned are just fine. Eat beef."

"In other words, it's not that which dish is poisonous, but the beef that is used for cooking is poisonous." Han Bin's expression was serious.

The problem is probably more serious than he thought.

If it is only poisoning inside the restaurant, then as long as the Wells restaurant is sealed, it will not cause harm to the people, but if the raw materials are poisonous, then the toxic ingredients may enter the people's table.

"We think so too." Tian Li said.

"This clue is very important and must be confirmed as soon as possible." Han Bin responded and called Zhou Yanjun. He wanted to interrogate Xu Weiming again.

...

Five minutes later, the interrogation room.

Xu Weiming was taken to the interrogation chair, looked at Han Bin, then at Zhao Ming, and asked: "Officer Han, what are you looking for?"

"Have Xu Weiming heard the phrase'be lenient in confession and strict in resistance'?"

"I've heard, Officer Han, I am willing to cooperate with the police in the investigation, and I will never conceal anything." Xu Weiming said.

"I have always heard people say that in order to recover the cost, the buffet will use some inferior and stale ingredients. Is there such a situation?" Han Bin asked.

"No, absolutely not. I'm a person who is good at doing things and will never be shoddy. We earn clean money and steady money. As long as the ingredients are fresh and taste good, there will be more customers, and I can make money." Xu Weiming said .

"Then why does Wells Restaurant buy poisonous beef?" Han Bin asked.

"This is impossible."

"We have asked people who are poisoned, and almost all have eaten beef-related dishes; while customers who are not poisoned have basically never eaten beef, how do we explain?" Han Bin said.

"Will someone poison beef?" Xu Weiming broke into cold sweat.

Being poisoned and purchasing poisoned beef are completely different in nature and he does not want to go to jail.

"There are at least seven or eight dishes made with beef, and the beef parts used in each dish are also different. Tell me how to poison it?" Han Bin asked back.

If a certain dish is poisonous, it is likely that poison is directly put into the dish, but now every beef dish is poisonous, it means that there is a problem with the beef.

"Could someone apply poison to the surface of beef?" Xu Weiming guessed.

"It's better to put that effort into the salt."

Han Bin snorted, "I have sent someone to check the beef stored in your restaurant. Don't take a fluke, understand?"

"Officer Han, I treat the restaurant as a lifelong career. I can't deceive consumers with inferior ingredients. That doesn't mean I smashed my own sign." Xu Weiming scratched his hair and continued:

"The beef in our shop is not lower than 26 yuan a catty at the forward price. Now the price of meat has risen. The purchase price of beef is at least 30 yuan a catty. Our family never buys inferior ingredients. They are the best. "

"When did the beef come in this time?" Han Bin asked.

"It seems to be yesterday morning."

"How much did you get in?"

"Half head."

"Where did you get in?"

Xu Weiming scratched his head: "I can't remember the specific location anymore."

"You didn't enter the beef yourself?"

"Our restaurant has a manager who is responsible for purchasing. He is responsible for purchasing the ingredients, and the chef is responsible for checking and accepting. I take care of a lot of things, and sometimes I can't take care of them." Xu Weiming said.

"Tell me the names and contact information of the manager and chef responsible for purchasing." Han Bin said.

"The purchasing manager's name is Wu Xiaohai, and the chef's name is Wang Biao. I can't remember the phone numbers, they are all stored in my phone."

"Where do the two of them live?"

Xu Weiming thought for a moment: "Wang Biao, I am not sure; Wu Xiaohai lives in Room 204, Unit 3, Building 6, Ziwei Home."

Han Bin touched his nose and asked: "Wu Xiaohai's address, how can you remember it so clearly."

"He is my brother-in-law."

Han Bin asked a few more questions, and then left the interrogation room.

Tian Li, Li Hui, and Sun Xiaopeng also walked out of the observation room on the side.

Han Bin glanced at the people: "You have heard the interrogation just now. My guess is that the cattle had eaten Tetramine before they died, so the place where the poisoning was done was not in the restaurant, but in the slaughterhouse or the farmer’s house. The source of the poisoned beef must be ascertained as soon as possible, otherwise, if the remaining poisoned beef is circulated and consumed in the market, more people will be food poisoned.

"Mother, these people are too wicked, and they dare to sell poisonous beef." Li Hui scolded.

"These people dare not do anything for money." Tian Li hummed.

"The domestic regulation of food is relatively lax. If he is abroad, he would have been punished early. Who would dare?" Zhao Ming said with emotion.

"Okay, stop complaining, I will arrange the task."

Han Bin interrupted the crowd and ordered: "Tian Li, Zhao Ming, please check the mobile phone number and address of chef Wang Biao, and summon him to the police station for interrogation."

"Brother Bin, do you want to apply for a warrant first?" Zhao Ming asked.

"I will call Team Zheng to apply for custodial summons, but this case is special. Poisonous beef may flow into the market at any time. Once more people eat poisoned beef, more people will be poisoned. Find Wang Biao's address, immediately arrest the person, and make up the formalities." Han Bin exhorted.

"Yes."

"Li Hui, Xiaopeng, follow me to arrest Wu Xiaohai. He is the head of the purchasing department and must know the source of the poisoned beef."

"Yes.

Subsequently, Han Bin and others acted separately.

In the car rushing to the Ziwei home, Han Bin called Zheng Kaixuan, reported the progress of the investigation, and told Zheng Kaixuan of his guess.

The ideas of Zheng Kaixuan and Han Bin coincide. There is nothing more important than the lives of the people. As long as the source of the poisoned beef can be ascertained as soon as possible, and more poisoned beef can be seized in the first time, all procedures can be completed.

No one knows how much poisonous beef is. This is the most terrifying thing.
