On the way to the hospital to investigate the clues, the first criminal investigation team was not idle.

Although the whereabouts of the nutrient solution have not been traced, they still have the nutrient solution as their main target.

The point is that there are too few clues now, and a breakthrough needs to be found.

Zhao Zicheng, as the captain, found the list of recent nutrient solutions and searched for them one by one to see if there were any fish caught in the net.

It was easy to formulate, but extremely cumbersome to implement.

"Captain, this list is some years old, some people have died or moved, and there is no trace of it."

Zhao Zicheng accepts other people's bitterness, but he will never allow him to give up.

"Does Zhao Yinsheng live here?"

"I am."

An old man with gray hair slowly opened the door, saw a group of young men standing in the doorway, pushed his eyes to identify, and found that he did not know, "Who are you?" ”

"Policeman, I'm here to ask you something."

Zhao Yinsheng turned sideways and let them in, "Come in and talk about it." ”

Zhao Zicheng took the others to sit on the sofa, "I heard that you can make nutrient solution?" ”

"Yes." The old man put on a pair of reading glasses, "I am a retired professor, and my specialty in school is in this regard, you can rest assured, it is absolutely safe, and there are no side effects." ”

He seemed very afraid that the police would not let him sell it, because the nutrient solution requires medical records to sell, and he has violated the bottom line of the law.

"In the beginning, I was treating my lover." Zhao Yinsheng thought that they were going to confiscate the nutrient solution, "Although I had money, I didn't cure it, so I left." ”

"And now?" Zhao Zicheng asked, "Your lover is dead, who are you selling nutrient solution to?" ”

"Poor." The old professor's voice was low, with the breath of twilight, and his cloudy eyes stared blankly ahead, "Vegetative." ”

"She died, and just when I wanted to give up, those people came to me."

"The nutrient solution in the hospital is too expensive, and I can't buy it for a long time, and in terms of efficacy, I have the same as the pharmacy here."

The old professor still clearly remembers that many family members wept and begged him to continue.

This is no longer for himself, a person's life even depends on his nutrient solution to survive.

"I can't refuse them." The old professor covered his face and sighed sadly, "They are all hard-working people." ”

No one thought of this answer, thinking that the old professor later relied on selling nutrient solution to make a huge profit to ensure a source of income, but the selling price was far lower than the market price, which can be said to be free charity, which greatly reduced the burden and brought a lot of new hope to the patients and their families who were emptied of money by the disease.

This result made everyone sigh.

Finally, the old professor took them to the place where the nutrient solution was made.

"It's all regular equipment and medicine."

The old professor introduced them one by one, each of them was a very important item to him, and now it may be confiscated soon, although he is very reluctant in his heart, but there is still no way.

From the moment he promised the vegetative family, he had already expected this outcome, and it was just a matter of time.

Zhao Zicheng looked over, the environment was clean and tidy, and the corners were regularly disinfected, which looked very formal.

After learning some information again, Zhao Zicheng asked, "Is there a list of nutrient solutions for sale?" ”

"Yes, yes."

The old professor hurriedly rummaged through, "I sell all old customers, so I am more assured, and the records are all there." ”

Handing over the somewhat worn notebook to Zhao Zicheng, the old man had already accepted the reality and was waiting for the final trial.

Zhao Zicheng was silent for a long time, and waved his hand to several other people behind him, "Found it, let's go." ”

A few people passed by the old man like this.

Back in the police car, someone asked Zhao Zicheng, "Captain, did you let him go like this?" ”

"Send someone to keep an eye on the situation." Zhao Zicheng rubbed his eyebrows, "Contact the community to protect him." ”

After making sure that everything is correct, they check one by one according to the list provided by the elderly.

There are a lot of people involved, but what the old professor said is not wrong, they are all family members of vegetative people to buy.

intensified the investigation, and finally locked down a middle-aged man named Liu Yi.

"Captain, he bought the nutrient solution, but there are no vegetative people at home."

Someone was overjoyed and finally found the suspect.

Zhao Zicheng immediately had people arrested, and Liu Yi was immediately taken to the interrogation room.

"What do you buy nutrient solution for?"

Liu Yi's psychological quality is not good, and after hearing the question, he replied, "Just use ......"

"For whom?" Zhao Zicheng stood up with his hands on the table, "Don't think about quibbling and lying, since we can bring you, it means that we have the evidence." ”

"I bought it for someone else!" Liu Yi panicked all of a sudden, he didn't know why he was helping someone buy something, and he was arrested for some reason.

He didn't want to carry this pot, and immediately explained the matter clearly.

"Someone approached me and asked me to help buy two bottles of nutrient solution." Liu Yi swore, "I didn't tell half a lie. ”

"The person's name, and other information."

Liu Yi couldn't answer all these questions.

"It was very dark, and I was walking in a small alley, and the man suddenly stopped me."

"I'm usually nosy, so I help when I have time."

Liu Yi said briefly, "There are no street lights in the alley, and the person is dressed in black, I can only hear that it is a man." ”

The killers were more cautious than they thought.

"How was the money given to you, do you have an account?"

"Nope." Liu Yi replied honestly, "After he asked me to buy it, I waited for him to meet at the same time in this place." ”

"The guy handed me cash too, twice as much as normal."

Liu Yi regrets it very much now, but he didn't expect to be involved in a case because of this.

After confirming that the other party was not lying, Zhao Zicheng warned, "Now it's a murder case, the person who asked you is the murderer, if he used some tricks at that time and wanted to kill people, you don't know where to lie now." ”

Liu Yi was frightened, and then he really felt afraid, he didn't expect that it had something to do with the murder, and hurriedly promised that he would never help others blindly in the future.

"This murderer is too cunning."

The police officer who made the transcript couldn't help but sigh, "He even prepared so much cash, just to prevent others from leaking it." ”

"It's a good luck thing for this man." Zhao Zicheng said, "At least it gives us a clue." ”

What he said to Liu Yi just now was not all intimidation, and he was indeed very lucky to survive under the hands of a murderer with extremely high psychological quality.
