The test results confirmed that seven groups of fingerprints were found in the old newspaper. One group belonged to Chen Yayan, the other group belonged to Zhang Baonan, and the other group was found in the fingerprint library. This person once had a criminal record and is now released from prison after being sentenced. The police went to his residence to find him and confirmed that he was a hawker selling department stores on the street.

The vendor was taken back to the criminal investigation team, and he kept shouting unjustly, "It's my fault to buy randomly, but it's not necessary for your criminal investigation team to arrest me, right?"

The criminal detective put the murderous knife in front of him and asked, "Look, do you sell this knife?"

The vendor looked at it and said, "I don't only sell this kind of fruit knife, but there are many ten-yuan stalls." The so-called ten-yuan stalls he called were to take a lot of department stores, all kinds of gadgets piled up in front of stalls, and people could choose them all for ten yuan each. And these fruit knifes also cost ten yuan each.

"Do you know this newspaper? This newspaper has your fingerprints and it is found that this newspaper once included this fruit knife. Remember carefully whether this knife was sold from your stall." The agent added another intimidating sentence, "I warn you, you'd better think clearly. This is a murder case, and your fingerprints are on the knife and on the newspaper. If you can't explain it clearly, we have to sue you for murder."

Wei Keliang glanced at the agent and reminded him to pay attention to the way he asked.

The agent looked up and smiled at Wei Keliang, then lowered his head and stared at the vendor fiercely.

When the hawker heard the agent say this, he was so scared that he was trembling all over. He had been inside, but he was beaten to death and was unwilling to go back to prison. What's more, he has always been obedient and never done anything illegal after he was released from prison. Of course, being a hawker is illegal at most and not illegal. This has always been clearly distinguished in his heart.

He racked his brains to think for a moment, then looked at the newspaper again. When his eyes fell on the yellow marks on the newspaper, his mind suddenly flashed and he hurriedly said, "I remember, this knife was bought by a woman."

Wei Keliang looked at the agent, and the agent asked, "Are you so sure?"

"Of course, it was definitely the time when the woman came to buy the knife at around 7 o'clock in the evening. Uncle Liu, who sold durian next door, invited me to eat durian. We also talked for a while and said that business was not good recently and it was difficult to do it. When the woman came to buy the knife, I just finished eating durian, so I picked up a newspaper and wiped it. Later, when the woman bought the knife, I still wrapped the fruit knife with the newspaper that had wiped my hand. The woman even asked me to change another one with disgust. Who knew that the urban management came at this time, and I quickly urged her to give the money and pack up the things. The woman later scolded me for being crazy. I was busy packing things, but I didn't even pay back."

The agent said loudly: "Who are you lying to? The urban management team has come to you and can you clean up the stalls of such a large one? I'm afraid that before you have finished halfway, the urban management team will help you get all of them into their cars."

The vendor remembered the source of the knife and felt relaxed. He smiled and said, "They won't really take our things, they just came over to do it. They came with a camera and said that they wanted to enforce the law now. You can ask the urban management in the East District. That day their camera probably took the woman down."

The agent snorted, "Of course we will go to investigate. If I know you are lying, I will not spare you."

The vendor said, "I haven't done it before, you can't wrongly accuse me."

Wei Keliang took out two photos, put them on the interrogation table, and asked, "Look, which of these two women is the one who went to buy a fruit knife?"

The vendor pointed to one of the photos and said, "It's her, it's her, I recognized it at a glance."

Wei Keliang put away the photo and said, "Well, thank you for cooperating with the police investigation, you can leave."

The vendor jumped out of the door three times. After leaving the door, he looked back proudly and asked the agent, "What case are you investigating? Did the knife I sold to kill someone?"

"You seem to be very happy!" The agent glanced at him, "Do you want to go in and squat for a few more days?"

The vendor waved his hands repeatedly and said, "I won't go. I am now law-abiding and a good citizen."

"Hmph, a hawker who blocks the streets, is so embarrassed to say that he is law-abiding? A good citizen? Forget it, don't be too proud and be a human being with your tail between your legs." The agent warned him.

The vendor was scolded with a gun and a stick, and left in shame.

After receiving a call from Wei Keliang, Jing'er and Lin Lefeng were on their way to the hospital.

"You are so efficient in your work. You brought people back for a question in such a short time." Jing'er praised.

Wei Keliang said: "Isn't this easy? I can only say that this time we have a good fortune and meet a knife seller with a criminal record. Otherwise, the sea is vast and I really don't know where to investigate! The vendor recognized that Chen Yayan was the one who bought the knife. Then, the accusation of intentional murder is basically unfair.

"Thank you!" Jing'er smiled.

"I thank you. This, to thank you, why don't I treat you to a meal, just tonight, okay? Don't push me away." It's not a matter of "coveting" Jing'er for a day or two, and everyone in the bureau knows it.

Jing'er glanced at Lin Lefeng. Lin Lefeng drove the car with a buzzing look, his eyes squinted over, carrying a raging fire.

"Okay, please call me after you set a time and place." Jing'er quickly agreed. It was time to explain it to Wei Keliang tonight.

Wei Keliang seemed very happy. After hanging up the phone, he immediately called to order a table.

In the hospital, Jing'er and Lin Lefeng came into contact with Zhang Baonan's parents. They were deceived by Yang Ruhai to the office and said they wanted to talk to them about Zhang Baonan's situation.

When they realized that Jing'er wanted to ask Chen Yazhu, both old men sighed, and Zhang Baonan's mother said, "Although Yazhu almost killed Baonan this time, we two old men did not blame her. Who told Baonan to do such a thing? Both of them regard Yayan as a child, and who expected that such a thing would happen?"

The double betrayal is a fatal blow to Chen Yazhu. Whether it is the elderly Zhang Baonan and his wife, Jing'er and his wife who are out of trouble, and the very happy Yang Ruhai, they can understand Chen Yazhu's pain by just a little imagination or even thinking from the perspective of others. Outsiders can't do such a thing to hurt Chen Yazhu, why does her own sister Chen Yayan kill her without leaving any room for her? Even after hurting her, she even falsely accused her of intentional murder, as if she didn't die, and she would be uneasy.

"What kind of person is Chen Yazhu usually like?" Jing'er asked the two old men.
