After Su Yan and others had eaten, the group left the food stall and came to Lu Ji's Salted Duck Restaurant.
They did not enter through the front door, but entered the store through the back door.
After entering, Su Yan glanced around and found that there were a large number of police officers busy at the scene. There were police officers of all types, some of whom Su Yan knew and some whom he did not recognize.
"Brothers, you go to eat, leave this place to us for now."
Zhao Yang shouted to the policeman who stayed behind.
It turned out that the scene was divided into two groups, one group stayed behind and the other group went to eat.
The police who stayed behind handed the scene over to Zhao Yang and others, and they went to eat one after another.
The Lu Ji workers and their families were detained at the scene. After Su Yan entered, he glanced at them and found that everyone was pale. Apparently they all realized that something big had happened.
After Su Yan withdrew his gaze, he said to Zhao Yang: "Zhao Da, take me to see the place where ducks are slaughtered."
Zhao Yang agreed and took Su Yan to the slaughterhouse next door.
This is a large, empty house with several faucets connected around it, and there is a fishy smell in the air.
Except for the front door, the windows all around the house are very narrow and more than two meters high. It is obviously impossible to climb in through the windows.
"When we came, all traces of the scene were destroyed, and the technicians did not extract any valuable evidence."
Regarding the destruction of the scene, Zhao Yang shook his head with an ugly expression.
"What kind of poison has it been found out?" Su Yan turned around and asked Zhao Yang when he saw that there was indeed no clue or evidence at the scene.
"Further testing is still ongoing. It should be a dilutable poison. The suspect poisoned the duck through injection." Zhao Yang replied.
Su Yan nodded. Since he still doesn't know what the poison is, if he wants to trace its source, he has to wait for the results to come out.
However, this case has a huge impact and time waits for no one. It seems that now we can only start with Lu Ji.
Su Yan: "What steps does the salted duck go through from purchase to shipment?"
"Lu Ji ducks are always purchased from a farm in the suburbs. There are three fixed people who purchase the ducks every day. After they are purchased, they are slaughtered and plucked by seven workers, and then marinated by the Lu family."
"Does that mean that in addition to the Lu family, the three people who bought the ducks and the seven workers who slaughtered the ducks are also suspected?" Su Yan asked.
Zhao Yang nodded: "We have focused on interrogating these ten people, but we have not found any doubts or evidence."
After saying that, he remembered something and said again: "According to the person who inspected the poison, the poison is very toxic. If it is injected directly into a living animal, the living animal will not survive, so the three people who bought the live duck should not be suspicious." .”
Su Yan understood what Zhao Yang meant. Since the three purchasers brought back live ducks, their suspicion was indeed low.
"Lv Ji has been braised salted duck for decades. You should be able to find differences in the duck injected with poison? Why didn't you notice anything unusual about the duck this time?"
Su Yan asked.
When Zhao Yang heard this, he couldn't help but smile bitterly: "The boss of Lu Ji is called Lu Jialiang. He drank too much in the morning and worked in a daze, so he didn't notice anything unusual about the duck."
"Drinking so early in the morning?" Su Yan shook his head, "This Lu Jialiang is quite confused."
"Now his intestines are full of regret, but it doesn't help anymore." Zhao Yang was also quite angry at Lu Jialiang's confusion. If he hadn't been greedy, this thing might not have happened.
"I'll look at the interrogation transcripts of the seven slaughtering workers."
Seeing that nothing was found at the scene, Su Yan asked Zhao Yang.
"Okay, they've finished recording their transcripts, I'll give them to you!"
Zhao Yang took Su Yan to a box in Luji Banya. The table in the box was piled with materials, and several policemen were studying it.
They saw Su Yan and Zhao Yang coming in and greeted them.
"Show Xiao Su the interrogation records of the seven workers who slaughtered and processed the ducks." Zhao Yang said to one of them.
The policeman picked up seven transcripts on the table and handed them to Su Yan.
Su Yan saw that each transcript spanned several sheets of paper. It was obvious that the interrogator had done a lot of work and the interview should be very detailed.
Holding these seven transcripts, Su Yan sat aside and read them alone.
Zhao Yang made a cup of tea for Su Yan, then winked at everyone and told them to move gently and not to disturb Su Yan.
Everyone at the scene knew that Su Yan was very capable in solving crimes, so they all immediately became cautious and deliberately did not make any noise.
Su Yan read the transcript very quickly, almost reading the entire transcript at a glance, and immediately raised his eyebrows.
"Have you finished reading?" Zhao Yang asked in surprise.
Su Yan nodded.
"Can you find out which of the seven people is the most suspicious?" Zhao Yang asked.
Su Yan did not answer, but asked Zhao Yang: "There are one hundred and eight salt ducks, how many of them can you know where they are now?"
Zhao Yang didn't answer this time, and the policeman next to him immediately said: "According to the notices and investigations from various police stations, we just sorted it out and found that currently all 108 salt ducks have been accounted for, and only 27 were poisoned. It’s not expanding.”
When Su Yan heard that all 108 salt ducks were missing, he immediately said: "That means the poisoner poisoned twenty-seven salt ducks."
Everyone nodded.
Su Yan immediately pulled out two of the seven transcripts. He tapped the two transcripts with his hand: "These two people are very suspicious!"
Zhao Yang took a look at the two transcripts and found that the people being questioned were named Zhou Fen and Li Yunxia.
"Why are they the most suspicious?" Zhao Yang and others asked at the same time in shock.
They had read the transcripts of the seven workers more than once, and they were already familiar with the contents, but they did not find any doubts.
Su Yan just took a quick look and came to a conclusion?
Even Zhao Yang couldn't help but be confused this time.
Su Yan replied: "I read the transcript just now. Lu Ji calculated their wages as piece-rate wages, which means that each person will be paid as much as they handle the number of ducks."
Zhao Yang and others nodded, they also knew this.
"In addition, each person is responsible for delivering the ducks he handles to boss Lu Ji for further processing, so it is difficult for criminal suspects to secretly inject poison into other people's ducks."
Zhao Yang and others nodded again, it was indeed the case.
"The clues will come out like this." Su Yan said with bright eyes.
"What clue?" Everyone still didn't understand.
"These seven people each handled more than a dozen or twenty ducks, but none of them manually handled more than twenty-seven ducks. In other words, if there was only one suspect, she would not be able to inject twenty-seven ducks."
"But it's a coincidence that this week Fen and Li Yunxia handled exactly twenty-seven ducks. In this case, it's worth our vigorous pursuit of these two."
Good guy!
When Zhao Yang and others heard this, they couldn't help but take a breath.
During their previous interrogation, they only thought that the suspect might be the same person, but they never thought that they were jointly committing the crime.
In addition, Su Yan used workers to handle the number of ducks, thereby focusing the criminal suspects on Zhou Fen and Li Yunxia. This investigation method and idea are also unique!
