"Xiao Su, could it be a coincidence that you previously concluded that the number of ducks killed by Zhou and Fen was a coincidence?"
Although others also thought that Su Yan's previous inference might be a coincidence, they couldn't ask directly.
Zhao Yang has collaborated with Su Yan many times, and they have a very good relationship, so Zhao Yang asked more directly.
Su Yan thought for a while, shook his head and said, "It can't be a coincidence, otherwise it would be too coincidental. They happened to slaughter twenty-seven ducks, and there were also twenty-seven poisoned ducks."
"But Zhou Fen and I have admitted that they only poisoned six animals in total." Zhao Yang said helplessly.
Su Yan flicked his fingers on the table again, and then stopped suddenly: "I guess it may be the second poisoner who is framing these two people."
"For some purpose, this person was also planning to poison, and he happened to be aware of Zhou Fen's poisoning operation, so he simply poisoned the other twenty-one ducks."
"If we hadn't discovered the relationship between the number of poisoned ducks, then they would have been fine. If we had discovered it, we could have put all the responsibility on Zhou and Fen."
When Zhao Yang and others heard this, they couldn't help but nod.
"Xiao Su's analysis is very reasonable. It seems that this second or second batch of poisoners are extremely cunning!" Zhao Yang frowned again.
"Da Qiang, please immediately take someone to check the bags of other suspects to see if there is residual venom in them too!"
Zhao Yang wanted to follow Su Yan's previous findings and use the same method to find out the second suspect.
The policeman who was summoned to Daqiang immediately agreed and went out to take action.
Su Yan asked Zhao Yang at this time: "Why did Zhou Fen and Li Yunxia poison themselves? What was their motive?"
Zhao Yang handed the two records on the table to Su Yan: "According to the two people's confessions, someone was prepared to buy Lu Ji's salted duck recipe at a high price, but Lu Jialiang was unwilling to sell it."
"That person secretly colluded with Zhou Fen and asked them to poison him to ruin Lu Ji's reputation, so he could buy it again."
Su Yan took the transcript and read it quickly, and couldn't help but wonder: "Zhou and Fen don't know the origin of that person? They don't even know the other person's last name? It's really stupid to believe what he said!"
Zhao Yang sighed: "Money can make people stupid. When Zhou Fen and Zhou Fen saw money, they were easily fooled."
"I have asked people to take Zhou Fen back to the city bureau to make criminal portraits, and reported the matter to Bureau Dai. He said that he would immediately ask all police stations to investigate this person." Zhao Yang added.
Su Yan nodded slightly. Although he knew the general appearance of this person based on the two people's descriptions, it was not easy to find him in the vast sea of people.
He read the transcripts of Zhou Fen and the others again, and frowned again: "That person also gave the venom to Zhou Fen and the others. They didn't even know what the venom was, so they dared to poison them."
Zhao Yang and others all had cold expressions on their faces, obviously very angry at Zhou Fen's stupidity.
"Does Lu Jialiang know some information about the instigator?" Su Yan asked Zhao Yangdao again.
Zhao Yang said: "When we first took over this case, we suspected that someone was poisoning after failing to buy it, so we specifically asked Lu Jialiang if there was such a person, but he said that several people would come to buy it every month, but he refused. Some people I don’t even know.”
"But now that we have this appearance and appearance, we can ask Lu Jialiang to ask."
With that said, Zhao Yang asked someone to call Lu Jialiang again.
After a while, Lu Jialiang followed the police who called him.
Lu Jialiang's usually well-maintained face turned almost earth-colored at this time, and his face was full of worry, making him look much older all of a sudden.
"Boss Lu, there is such a person. Let me describe it to you and see if you recognize him?"
Zhao Yang described the appearance of the person who instigated Zhou Fen and Li Yunxia.
Lu Jialiang thought for a long time, but shook his head heavily: "I don't know him. Although there are many people who want to buy my store, I have no impression of this person."
"oh"!
Although they had expected that the person would not be exposed so easily, everyone was still disappointed when they heard Lu Jialiang's denial.
Zhao Yang waved his hand and signaled Lu Jialiang to leave.
Before Lu Jialiang left, he asked worriedly: "Da Zhao, can my case be solved?"
Zhao Yang understood his mood at this time and comforted him: "Don't worry, we will do our best."
Lu Jialiang nodded. Although he thanked him, his eyes were dim, and he obviously didn't believe what Zhao Yang said.
After Lu Jialiang left, someone asked Su Yan: "Officer Su, could the second or second batch of poisoners be instigated by this person?"
Su Yan said: "There is currently no evidence or clues. No one is sure about this."
Everyone nodded in understanding. After all, Su Yan was not a god who could make calculations with his fingers. Any inferences and analyzes of the case were based on existing facts.
Even a clever woman cannot make a meal without rice!
While everyone was discussing the case, Daqiang ran in panting.
"Da Zhao, Officer Su, we checked everyone's bags and found no residual venom!"
When Chaoyang and others heard this, they all showed a hint of disappointment.
Only Su Yan seemed to have expected it. He nodded and said: "It seems that the second person's poisoning method is different from Zhou Fen and others."
After Zhao Yang and others were disappointed, they took the transcripts of the remaining five criminal suspects and studied them again.
The seven people who slaughtered the ducks are all suspected. Now, excluding Zhou Fen, there are only five people left.
Will the second poisoner be among these five people?
With this question in mind, everyone began to study it silently.
After some research, everyone finally shook their heads. The number of ducks killed by the remaining five people could not be twenty-one no matter how they were combined.
"Maybe someone didn't poison all their ducks." Someone speculated.
Zhao Yang nodded and said: "It is possible, but in this case, it will be difficult to find the second poisoner through this method!"
Everyone couldn't help but sigh.
Just as everyone was discussing the next action plan, Zhao Yang's police call suddenly rang.
After he got through, his face lit up. After hanging up the police call, he told Su Yan and others: "The technicians have already figured out what the venom is!"
"What kind of poison is it?" Su Yan and others asked immediately.
"Phosphorus pentoxide!" Zhao Yang said slowly.
Although everyone at the scene did not know much about various poisons, they had been dealing with technicians for a long time and knew what phosphorus pentoxide was.
This phosphorus pentoxide dissolves in water and forms metaphosphoric acid, which is extremely toxic.
Everyone was shocked when they heard that the poisoner used this poison.
"Were all the poisoned people poisoned by phosphorus pentoxide?" Su Yan asked Zhao Yang.
Zhao Yang nodded: "It's all this kind of poison."
Su Yan flicked his fingers on the table and suddenly said: "This is strange. How could Zhou Fen and the second or second batch of poisoners be so coincidental and use the same poison?"
Everyone was shocked, Zhao Yang's eyes lit up, and he immediately said: "Didn't this second person temporarily notice the two's behavior, but already knew that they were going to poison, and thus prepared the same poison as them?"
