In the afternoon, the criminal investigation detachment, the toxicology laboratory.

"Of the seven bottles of medicine you brought back, four of them were rat-poisoning." The forensic doctor in charge of the toxicology test said: "The other three bottles are also banned by the state from being produced and used. ”

After a pause, he said again: "As for the packs of so-called 'Miao Medicine' you bought, they are fake, useless, and add a lot of messy things, which are harmful if you don't do it well."

I do not deny that 'Miao Medicine', 'Mongolian Medicine', 'Tibetan Medicine' and 'Traditional Chinese Medicine' do have their own unique features, and I have personally studied them and quite appreciated many of them.

But the problem is that there are too many people who swagger and deceive under these banners, as well as brainless blowing, and the combination of the two has brought fatal damage and destruction to these traditional medical skills. ”

"The key is to intensify the crackdown." Brother Song followed his words, and then quickly diverged and said, "You are busy first, I have to quickly arrange for someone to arrest these seven illegal traders who sell highly toxic substances that are prohibited from production and use, so as not to leak the news." ”

"Okay, there you go."

……

In the evening, the seven suspects were brought back to the criminal investigation detachment, where they were interrogated one by one and given a set of photographs for them to identify.

Brother Song and Qi Yuan interrogated the little brother who claimed to be a Miao person.

"What's your name?"

"Song Zucong."

"Age?"

"Thirty-four."

"Origin."

"A native of Ludi Quancheng, Han nationality."

"Didn't you say you were a Miao?"

Song Zucong stiffened his neck: "If you don't say that, can people believe the Miao medicine I sell?"

What can I do, people don't believe it if they are good businessmen, as soon as they say that they are from the Miao family, they have a lot of brains, and they sell very well. ”

"Why is it strong to sell poisonous rats?" Qi Yuan rolled his eyes and asked.

"What rat poison is strong?"

Qi Yuan took out a bag of evidence, which contained the medicine he sold: "This thing, poisonous rats, is highly poisonous, and it has been strictly forbidden to produce, sell and use it many years ago. ”

"What the hell? I don't know, people didn't tell me when they bought it, they just said that the special medicine was particularly useful. He panicked and said, "You ...... You guys are fishing for law enforcement! ”

"You can complain," Brother Song said lightly: "Your phone is still on you, and I can also report the complaint phone to you." ”

"You...... You are so rampant that you are not even afraid to complain......"

"All of our actions are within the scope of legal permission, and there are even video recordings throughout the whole process, but you didn't find out, why be afraid?" Brother Song said softly: "Fishing law enforcement, we fish first, inducing you to commit a crime, naturally you are not allowed, you are not guilty in this situation."

But the fact is that you committed the crime first, and we set up a trap only to arrest, not to convict, and we don't need the objective fact that 'you sold contraband to us' as evidence, naturally......

Forget it, if I don't explain to you, your culpability is not serious, and it is estimated that it will not be long before you can wait for a speedy trial, and then there will be a public prosecution lawyer to defend you, if you have doubts, ask him directly. ”

After speaking, without giving him a chance to refute, he took out another stack of photos: "Okay, don't quibble, the facts are clear and the evidence is complete, so you can't quibble." Now do us a favor and strive for the opportunity to make meritorious contributions, and maybe we can reduce our sentence. ”

His eyes rolled: "What do you want me to do?" ”

"Let's see if any of these people you have seen or bought medicine with you." Brother Song said: "Something happened to the medicine in his hand, you have to be able to recognize him and give you a great credit." Of course, if you say it in advance, whether you can be punished lightly doesn't matter, and it depends on you whether you cooperate or not.

Look carefully, think about it, don't talk nonsense, otherwise it will not only be useless, but also a major demerit, and the sin will be added to the first degree. ”

"Then I'll try." He rolled his eyes again, no longer defending himself, and nodded.

The photos are put down one by one, divided into several groups, each group of ten, ten after the end of the ten to ask him if he knows, if not directly, if there is one, then sweep to the side and continue to put.

After several sets of photos, only one group had people he thought he was familiar with, so Brother Song took this group of photos again, unfolded them one by one, and finally asked him to choose which one he knew.

He launched a photo.

"Cao Xian?" Qi Yuan glanced at the photo, was slightly stunned, and thought to himself: "Isn't this the resident doctor whose ex-fiancé gambled on a lot of debts and finally pushed the contract to break up and change his personality greatly?" ”

Brother Song was also a little surprised, but quickly asked, "How did you know her?" ”

"Last week, she came to me to buy medicine."

"What medicine to buy?"

"As for the one you bought, she said that there were rats in the house, and she couldn't kill them cleanly, so she asked me if I had anything powerful, so I gave her this."

"Poisonous rats are strong." Brother Song pursed his lips and glanced at Qi Yuan, Qi Yuan understood, and immediately sent a message to Su Ping.

……

Nine o'clock, evening meeting.

There were still a few criminal policemen who had not arrived, so Xun Mu decided to wait for a while, so he communicated privately with the few people present first.

"It's not Cao Xian's poison," Su Ping said, "She did buy rat poison, but she didn't open it, and she didn't have time to use it."

And she does have a lot of rats in her house, after all, the environment is not very good, in the urban village, and she doesn't know what kind of medicine she bought, she just bought it home with the idea of giving it a try, and then forgot about it, it was never useful, so she was not very suspicious.

The most important thing is that the toxicology laboratory has examined it, although the bottle is the same, it looks very similar, it is all white powder, with a little crystal, but it is not strong in the poisonous rat, but cholecalciferol.

In fact, it is vitamin D3, which is not a strictly controlled drug, nor is it a prescription drug, although it can also be used as a rodenticide, but it is not very widely used.

It is estimated that it should be a guy named Song Zucong, in addition to the problem of the purchase channel, it is estimated that he did not tell him what kind of medicine he was selling, but only told him that it must be effective, so cholecalciferol and rat poison were mixed and sold to him.

Therefore, Cao Xian's suspicion can almost be ruled out here. ”

Brother Song wondered: "Since it's not Cao Xian, who could it be?" Of the seven vendors, three recognized Cao Xian, but none of the others. ”

"It means that the murderer didn't buy the medicine at that farmer's market." Xun Mu took over and said, "Or maybe I didn't go today." Itinerant vendors are not fixed, and the market administrator collects rent on a daily basis, and it is normal for a day not to pass.

In short, there are already eyebrows, your thinking should be correct, continue to investigate, the breakthrough of the source of poison should be opened soon. ”

"What about the rest?" Brother Song asked again: "Zhang Haiming still has the patient's family sealed, have the two most suspecting people made breakthroughs in other aspects?" ”
