After reading the interrogation transcripts of Wang Hai and others, Su Yan had a general understanding of the poisoning process of the Zhu brothers.
Zhu Jian is the eldest brother of the Zhu family. He bought a salted duck from Luji today. When he came back, he met Wang Hai and the others and showed off, saying that he had eaten Lvji salted duck today.
The two sides joked with each other, and Zhu Jian took the salted duck home.
When Wang Hai went home and finished his meal, he came to chat with the Zhu brothers, only to find that Zhu Jian and Zhu Guo had been poisoned.
When Wang Hai saw him, he hurriedly called his neighbors and sent his brother to the hospital, but in the end he could not be saved.
After Su Yan read the transcript, he asked Sun Fuli: "Have you put away the remaining salted duck?"
Sun Fuli was startled, then shook his head and said: "When we arrived at the scene, we didn't see the remaining salted duck, not even the bones, only this Lu Ji packaging bag."
With that said, Sun Fuli opened the evidence bag and took out a Lu Ji packaging bag.
"Didn't you find the remaining salted duck?" Zhao Yang couldn't help being surprised and asked.
Sun Fuli said firmly: "No."
"You didn't ask the neighbors next door who might have cleaned the scene?" Zhao Yang asked again.
If someone took away the remaining salted duck and disposed of the scene, then he would be the most suspect, as he was obviously destroying evidence.
There was a hint of embarrassment on Sun Fuli's face. He thought this case was the same as other poisoning cases, so he didn't investigate it carefully at all.
When Zhao Yang saw Sun Fuli's expression, his heart sank. He and Su Yan exchanged glances, and Zhao Yang immediately said to his subordinates: "Immediately ask the next door neighbor again to see who may have taken the remaining salted duck?"
Sun Fuli thought about making up for his mistake and immediately said: "I will take you there."
More than a dozen people from the criminal police team and several people from the police station immediately went out to retrieve the transcripts from the relevant persons.
This time Zhao Yang personally led the team, and Su Yan did not go with him.
After everyone left, he picked up the Lu Ji packaging bag and looked at it carefully.
"Is there anything different about this packaging bag?" Cheng Qingli, who was standing next to him, saw Su Yan holding the packaging bag for a long time and walked up to him and asked.
"Oh? It's nothing, I just looked at the wrinkled packaging bag and thought it was a little strange." Su Yan put down the packaging bag and replied.
Cheng Qingli nodded: "Lvji is a famous brand store, so they shouldn't use old packaging bags. They pay great attention to details and reputation."
Su Yan smiled and said, "Do you know Lu Ji very well? Have you ever eaten their salted duck before?"
Cheng Qingli smiled slightly and said: "I spent my childhood in Jiangning City. At that time, my grandpa and grandma often bought Luji salted duck, so I know a little about them."
"Are you from Jiangning City?" Su Yan only knew that Cheng Qingli was from the provincial department, but he didn't know about the others. Now that he heard it, he was very surprised that Cheng Qingli was from Jiangning City.
"I'm half from Jiangning City. I lived with my grandpa and grandma since I was a child. When my grandma passed away after I graduated from elementary school, I went back to the provincial capital to study in junior high school."
Cheng Qingli explained.
"Oh." Su Yan nodded.
"We are about the same age. Which primary school in Jiangning City did you graduate from?" Su Yan asked casually.
"Jiangning Xinghua Primary School." Cheng Qingli replied.
"Really?" Su Yan said in surprise: "I also graduated from Xinghua Primary School. I graduated from the 14th class. What about you?"
"What a coincidence." When Cheng Qingli heard this, he couldn't help but smile in surprise: "I am also in Class 14, and I am in Class 3."
"Class 3? I know, the teacher of Class 3 is Mediterranean, and his surname seems to be Xu."
"Yes, yes, he is bald, and he likes to cover it with his side hair. Whenever the wind blows, his hair stands up and blows in the wind." Cheng Qingli couldn't help laughing.
"I also know that he has a very loud voice and likes to yell at people. Whenever your class has a class meeting, his yelling is transmitted to our class. I am in Class 7."
"I know that your class teacher is Teacher Zhang in Class 7. He is soft-spoken and the exact opposite of our class teacher!"
…
Neither of them expected that they were alumni of the same class. Suddenly there were many topics to talk about, and they both recalled the past with great interest, and their relationship suddenly became much closer.
While they were talking, Zhao Yang and others came back one after another outside.
"Let's have a good chat some other time, and maybe we'll have some classmates we know in common."
Seeing Zhao Yang and others coming back, Su Yan said to Cheng Qingli.
"Xiao Su, we have obtained the records of the relevant persons again. The matter is as you previously judged. The deaths of the Zhu brothers were strange!"
With that said, Zhao Yang put all the records on the table and asked Su Yan to read them.
Su Yan sat down at the table and started reading all the transcripts.
He flipped through it as quickly as ever, and when he finished reading it, he frowned.
According to the owner's record, Zhu Jian went home after buying Lu Ji's salted duck and showing it off to Wang Hai and others.
When Wang Hai came to chat with them after dinner, he found that the door of their house was not closed, and both brothers were lying on the ground, already poisoned.
Wang Hai called several neighbors to take them to the hospital.
As for the whereabouts of the remaining salted duck, Zhao Yang and the others focused on asking this time, but the neighbors next door gave the same answer. When they arrived at the scene, they did not see the remaining salted duck.
Su Yan thought for a while and read through the transcript again.
It was around 11:50 when Zhu Jian came back from buying salted duck, and it was around 12:20 when Wang Hai came to chat with them after dinner.
Su Yan put down the note and said to Zhao Yang: "The Zhu brothers were poisoned between 11:50 and 12:20!"
Zhao Yang nodded: "According to the transcript, it should be this time period."
Su Yan nodded and tapped his fingers on the recording paper: "During this period, no neighbors noticed anyone coming from the Zhu family."
Zhao Yang smiled bitterly: "Everyone was eating at home at that time, and indeed no one noticed that there were outsiders coming to the Zhu family!"
"Eleven to fifty-twelve: twenty?" Su Yan frowned slightly, "If the suspect takes away the remaining salted duck, or even bones and other impurities, it will take him a while to clean up the scene. So, time can tell Push forward until 12:15.”
Zhao Yang and others all nodded in agreement.
"This is strange." Su Yan raised his eyebrows, "The first person who was poisoned was confirmed at the hospital at 12:10, which means that within five minutes, the criminal suspect got the news and was ready. Metaphosphoric acid poisoning and a series of action plans implemented?”
"This is impossible. The time is too short. No matter how coincidental it is, even if the suspect already possesses metaphosphoric acid, he cannot complete this series of actions."
Everyone present shook their heads thoughtfully.
Regarding the time issue, Su Yan and Zhao Yang had previously discussed it at Lu Ji, but this time they checked again and found that there were many restrictions.
In other words, the previous discussion was inaccurate.
"The time was wrong, but the suspect actually carried out the action and poisoned the Zhu brothers to death!" Someone scratched their scalp in confusion.
Su Yan was speechless, and his eyes fell on the Lu Ji packaging bag again.
"We may have gone in the wrong direction." Su Yan thought for a moment and said suddenly.
Zhao Yang and others immediately looked at Su Yan.
Su Yan looked at everyone and said word for word: "So far, no one can confirm whether what Zhu Jian bought is Lu Ji's salted duck!"
