Criminal Investigation Detachment, Interrogation Room.

Xun Mu and Su Ping sat side by side, looking at Su Kaiyong opposite.

Like most of the suspects detained, he kept his head down, looking left and right from time to time, occasionally rolling up and down in his Adam's apple and swallowing a few mouthfuls of saliva.

"Why did you steal thallium sulfate?" Xun Mu flipped through the investigation report, put it down, and asked softly.

"Earn ...... Make hay. He swallowed and salivaed: "That thing is always valuable, a big bag of palms, can be mixed out of thousands of bottles of pesticides, a bottle of ten yuan is ten thousand dollars, just such a pack, they are not easy to find out no, the risk is low......"

"The risk of fart is low!" Su Ping slapped the table: "I lost more than 600 grams of highly toxic substances, our Yuqiao, Huzhou, and thousands of police officers from the public security in the two places have been transferred, and the whole city will be locked down and strictly investigated, you tell me that the risk is low?" ”

"I didn't expect you to take this thing so seriously."

"Still quibbling?" Su Ping snorted coldly: "From your home, only eight hundred bottles of pesticides were found, and 404 grams of thallium sulfate were extracted, where did the two hundred grams go?" ”

"I, I sold it." His eyes rolled.

"Sold to whom?"

"How do I know, if someone pays for it, I'll buy it."

"What about the money from the sale?"

"Spent. I owe a lot of debt, and I pay it back as soon as I have the money. ”

"To whom?"

"Give it back...... Give it back to ......" He got stuck.

"Still!" Su Ping clenched his fists: "Didn't you check your running water?" The more than 200 grams of thallium sulfate were poured into Su Haohu's seasoning box by you, right? ”

"It's not! I didn't! He waved his hand again and again: "He is my eldest nephew, how can I do this?" Don't talk nonsense, there's no such thing. Those 200 bottles of pesticides were really sold by me. ”

His eyes rolled again, and he suddenly said: "Fanchang Township, Dahu County, where it is sold, you go to ask, go to check, you should be able to find it!" ”

After a pause, he said again: "Hey, no, where did I get 600 grams, I stole a bag of medicine, 500 grams, don't slander me." I sold 200 bottles, and the first half of each bottle was about half a gram, which added up to just over 100 grams. ”

Su Ping frowned slightly.

Looking at his determined appearance, it doesn't seem to be a fake, but he can't tell where the money from the business has gone......

In addition, since he has admitted that he stole thallium sulfate, there is no essential difference between 500 grams and 600 grams, so where did the 100 grams that he denied go?

Or, he knew how Su Haohu died, so he deliberately said that he didn't know about this 100 grams of thallium sulfate? Speaking of which, there is not much thallium sulfate left in Su Haohu's food box, and it is estimated that it is exactly about 100 grams if you count the ones eaten by those workers......

After thinking about it, Su Ping spoke again: "I'll check, but now, you still have to tell me a good story, what's going on with this money?" You said that you paid off the debt, so, tell me, to whom? What can't be said about this? Could it be that you are also involved in other criminal activities? ”

"No, I didn't!" He said quickly, then lowered his head again, and squirmed.

Xun Mu looked at him, suddenly thought of a possibility, couldn't help but reach out to support his forehead, and asked, "You won't take it to prostitution, right?" ”

Su Kaiyong opened his mouth and stared at him in disbelief, then quickly lowered his head and said nothing.

"Hey, you!" Su Ping's eyes widened: "The family is in such difficulty, you still go to prostitution?" ”

Looking at his appearance, Su Ping only felt angry, patted the table, gritted his teeth and scolded: "No wonder your wife wants to divorce you!" Just like you, follow you, how can you live? ”

……

At the same time, the bear pesticide plant.

Brother Song and Qi Yuan were about to leave, but suddenly received a call from Xiao Gao.

After saying a few words, he frowned slightly, immediately hung up the phone, and at the same time called the criminal police of the Qihua County Criminal Investigation Brigade, and said, "Wait, I just found two pieces of information." ”

"Oh? How so? ”

"First, this pesticide factory did obtain the production and wage increase of thallium sulfate in the early stage, but the validity period has expired and has not been submitted for approval again.

You should be well aware that even if you have obtained the production qualification, the pesticide itself needs to be submitted for approval separately, and each product must be registered. However, they may find the procedures cumbersome and do not apply for a review after the expiration date. ”

The middle-aged captain nodded slightly, but this matter involved quite a lot, and it was related to many departments, and he felt a big head when he thought about it, so he continued to ask: "What about other than that?" What's the other news? ”

"We did find a pesticide containing thallium sulfate from Su Kaiyong's house, but after rapid distillation to extract the drug, we found that there were only 404 grams of thallium sulfate, and in addition, he admitted that 100 grams of it was sold by him with water, but the other 100 grams refused to admit it......

In short, he gritted his teeth and concluded that he had only stolen five hundred grams of thallium sulfate. ”

"What?" The captain was taken aback, and then forced himself to calm down: "I guess it's because someone was poisoned, he wants to quibble, right?" ”

"This possibility cannot be ruled out, but it is also not ruled out that more than one person stole thallium sulfate." Brother Song said solemnly: "I'm afraid we can't leave yet." ”

The captain frowned, and after a while, he gritted his teeth: "Cheng!" 100 grams of thallium sulfate is not a trivial matter, it is true that there can be no mistakes at all, and it must be checked clearly. ”

"Fortunately, there is good news." After thinking about it, Brother Song added: "Combined with the concentration of thallium sulfate in the body of the victim and the poisoned patient, the approximate intake is calculated, plus the remaining thallium sulfate in the seasoning box of the victim Su Haohu's house, which happens to be in the early 100 grams.

In other words, even if another thief exists, there is no thallium sulphate in his hand, and the theft is unlikely to have other worse effects. ”

When the captain heard this, he was obviously relieved, and said that it would be good, thought about it, and said: "I have already called the people of the detachment back, since the situation will not develop in a more serious direction, I will not let them come over again, right?"

In addition, if there is anything else you need help with, just say it, we will fully cooperate. ”

The words "help" and "cooperate", he said a little lightly, and seemed to be a little weak-hearted.

Brother Song glanced at him and nodded slightly, although he saw that he was shirking responsibility at this time, they were not responsible if something happened, and they were just helping to solve the case as a cooperating party, but they didn't solve it, at this time, it was good to be able to take the initiative to cooperate, and it was difficult to ask for too much.

Of course, the premise is that the 600 grams of stolen thallium sulfate have been directly or indirectly locked, otherwise, it will be their local criminal police's turn to be nervous.

"So, let's continue the monitoring. How many days does the plant monitor storage? ”

"Forty-five days." The detective replied: "It's a while, I'm afraid it won't be over." ”

"Let's divide it," the captain thought for a moment and said, "according to the time, it is divided into nine equal parts, and each person is responsible for five days of monitoring, screening out all those who have the conditions to come into contact with thallium sulfate." ”
