When Su Yan identified the two suspects Zhou Fen and Li Yunxia, everyone suddenly became excited.
One of them asked: "Officer Su, do we need to interrogate the two of them directly now?"
Su Yan thought for a while, and finally shook his head and said: "This is just my inference. Without relevant evidence, they will not confess easily."
Zhao Yang and others nodded. Without evidence, it is indeed not easy to get a criminal suspect to confess honestly.
"Did you find the syringe?"
It can poison ducks, especially dead ducks, and can only be injected with a syringe.
That's why Su Yan specifically asked this question.
When Zhao Yang heard this, he couldn't help but smile bitterly: "We searched the entire Lu Ji Salted Duck Store several times, but we didn't find any syringes at all."
Su Yan frowned. He had just observed that Lu Ji's Banya Store had sewers and toilets. If the criminal evidence was destroyed through these two places, it would indeed be impossible to find it.
Flicking his fingers on the table, Su Yan suddenly raised his eyebrows.
He turned to look at Zhao Yang and said with piercing eyes: "Zhao Da, please immediately have Zhou Fen and Li Yunxia's bags checked. There should be residual poison in their bags."
Zhao Yang and others were stunned.
Seeing that they didn't understand, Su Yan explained: "It's not easy to put a syringe on your body. If you are not careful, you may hurt yourself. In addition, if the venom is temporarily applied, there will be many people at the time, which is definitely unrealistic."
"So the two of them should have filled the syringes with venom before they came, and probably put them in their carry-on bag so they could be used whenever they could."
"If the syringe is placed in the bag, it will definitely pierce the surface of the bag, so there must be residual venom in their bag."
When everyone heard Su Yan's explanation, it was like waking up from a dream.
"Technician Lin." Zhao Yang immediately shouted to a criminal technician: "Immediately follow me to get Zhou Fen's wallets, and then inspect them on the spot!"
At this time, Zhao Yang was so excited that he even spoke with vibrato.
Su Yan's discovery was so important that as long as the two suspects had residual venom in their bags, they would never deny it.
At that moment, everyone hurried to the banya restaurant lobby.
At this time, all the employees of the Ban Ya Restaurant were in the hall. Zhao Yang glanced at them with a cold gaze, and then said: "Who are Zhou Fen and Li Yunxia, come forward!"
As soon as he shouted, the expressions of the two women changed.
Su Yan and others immediately focused their attention on them.
Under the gaze of everyone, Zhou Fen and Li Yunxia knew they couldn't hide it, so they had to stand up tremblingly.
When Zhao Yang saw that they all had leather bags in their hands, his eyes couldn't help but reveal a hint of joy, but his expression remained stern.
He winked at several of his subordinates, who immediately walked over and reached for Zhou Fen's bags.
"Hey, what are you doing with my bag?" Both of them were startled.
Apparently they had not thought that the police had identified them as poisoners and that there might be evidence in their bags.
Several policemen ignored them at all. After taking the bag, they handed it over to technicians for inspection.
As the technician took out the inspection tools and began to examine the leather bag carefully, Zhou Fen and Li Yunxia seemed to think of something at the same time, and their expressions suddenly changed.
They also tried to take back the bag, but several policemen who were watching eagerly nearby would not allow them to move.
"You'd better stay still, otherwise we'll use police equipment!"
Faced with the warnings of several police officers, Zhou Fen and Zhou Fen did not dare to move any more, but their expressions further changed and turned pale.
At this time, although other people in Luji Banya Restaurant didn't understand what was going on, they saw that Zhou Fen and Zhou Fen had something wrong on their faces, so they all vaguely guessed something.
The inspection didn't take long. Soon, technician Lin finished inspecting one bag, and then started inspecting another bag with a solemn expression.
At this time, the scene was silent, and everyone stared at technician Lin's inspection with wide eyes.
This time the time was shorter. After inspecting the second man's bag, he immediately raised his head and nodded to Zhao Yang: "There are venom residues in both bags!"
"Okay, okay!"
When Zhao Yang heard this, he excitedly said three good words in a row.
He stared at Zhou Fen and Li Yunxia, and ordered his subordinates with a cold face: "Take them away separately for further interrogation!"
When Zhou Fen and Li Yunxia heard that technician Lin said there was residual venom in their bags, their bodies couldn't help but tremble. Li Yunxia couldn't even stand still and almost sat on the ground.
Because the evidence was solid, Su Yan did not participate in the interrogation, but stayed in the hall with everyone to wait for the outcome of the interrogation.
The comrades who had gone to eat just now also received news that there was a major development in the case. They hurried back without even finishing their meal.
The entire Banya restaurant was full of people waiting for news. Although there were many people, everyone held their breath.
It didn't last long, but half an hour later, there was a sound of hurried footsteps, and Zhao Yang and his people appeared in the hall again.
When everyone looked at Zhao Yang's face, they couldn't tell whether he was happy or worried, and there was even something weird on his face.
"Police officers, are Zhou Fen and Li Yunxia really the poisoners?"
Before anyone else could ask, Lu Jialiang, the boss of Lu Ji, couldn't wait to ask.
Zhao Yang coughed, looked at everyone and said loudly: "Zhou Fen and Li Yunxia just confessed. They did poison the salted duck."
"well!"
"ah?"
When the police from the city bureau heard this, they all cheered happily.
But the employees of Lu Ji's Banya Restaurant all opened their mouths in shock. Apparently they didn't expect that the people who poisoned them were Zhou Fen and Li Yuxia.
"These two people usually seem to be honest, how could they do such a thing? I have no enmity with them, why are they trying to harm me?" Lu Jialiang shook his head in confusion.
Su Yan remained silent at the side. He saw that when Zhao Yang announced that Zhou Fen and Zhou Fen were the poisoners, his expression did not show any joy, but became more solemn.
Seeing Su Yan looking over, Zhao Yang nodded to him.
Su Yan understood and followed Zhao Yang back to the next box.
"Zhao Da, is there something wrong? Aren't Zhou Fen the two poisoners?" There were several other comrades who followed. They also saw that Zhao Yang's expression was wrong at this time, and they all asked hurriedly.
Zhao Yang looked at Su Yan and others and said word for word: "Zhou Fen and the others did poison, but they only admitted to poisoning six of the ducks, and they did not admit to the other twenty-one!"
"What?"
This time not only others, but also Su Yan were surprised.
"So, there are other people who poisoned the salted duck today?" Su Yan frowned.
Zhao Yang nodded gloomily: "It is indeed true. Zhou Fen and Zhou Fen must not have lied. There are other people who poisoned me!"
"Ah, is there another poisoner?"
When everyone heard the conversation between Su Yan and the two, they all gasped in disbelief!
Previously, Su Yan deduced the number of poisoned ducks and concluded that Zhou Fen and Zhou Fen were the poisoners. Is it a coincidence?
