Zhou Nan told the whole story of the incident. Gu Yanzhi frowned: "I know."

In the afternoon, the police summoned him, and Gu Yanzhi accompanied Zhou Nan to the police station.

Knowing that Gu Yanzhi had come with him, the director of the sub Bureau rushed out to meet him. Gu Yanzhi said without expression: "I just accompany my girlfriend to make a record, so I won't delay the director's time."

"It's all right. No delay. We're just making routine inquiries. Please don't blame the vice brigade."

"No, you're business as well."

"Thank you very much for your understanding. When Miss Zhou is taking notes, let's have a cup of tea in my office."

"No, I'm waiting for her outside the interrogation room."

"Good, good."

They all stood outside the interrogation room, looking at Zhou Nan through the glass.

Zhou Nan is She was very experienced, and the police on the other side had a very friendly attitude. She also comforted her for a moment: "we just ask a few questions on a regular basis. You don't have to be nervous."

"I'm not nervous."

"What is your relationship with the victim?"

"She's my father's second wife, but they divorced some time ago."

"How is your relationship with her?"

"It's never been good."

"Where were you on the day of the crime..."

……

Outside the interrogation room, Gu Yanzhi was also asking the director, "is there any progress in the case?"

"Yes, our people didn't find any tools at the scene of the crime before. But yesterday, Zhou Zhihai accompanied Zhou Nan, the daughter of the deceased, to the police station and handed over a willing dagger, which was stained with blood and Xie Rong's fingerprints."

"Only Xie Rong's fingerprints?"

"Yes, Zhou Ying took the knives carefully and wrapped them in cloth, so they didn't get fingerprints from other people."

"So, Zhou Ying has hidden important evidence. Where is she now?"

"Well, because it was her mother, she was out of her wits at that time, so she took the dagger by the way. She didn't know the law and handed it in later..."

"Oh? So she fooled the whole police system in a few words? "

"After all, the dead is her mother."

"The dead is her mother, so she can be extrajudicially grateful. Did she hide the dagger unintentionally or tried to draw it from others? Didn't you have a specific interrogation?"

"I'm sorry, deputy brigade. We'll review it again."

"If the dagger had been there in the beginning, and my girlfriend's fingerprints were not found on the dagger, then the bloodbath on the Internet would not be as serious as it is now. You are dereliction of duty."

"I'll have Zhou Ying brought back to the police station for detailed interrogation."

Gu Yanzhi waved his hand: "go."

After the director left, one of Gu Yan's companions was the leader of the first criminal investigation team. Gu Yanzhi said coldly, "is there any progress in the case now? Have you checked the cameras and everything? "

"By comparing the angle and depth of the wound by forensic medicine, suicide has been ruled out. Although the murderer tried hard to imitate the angle of suicide, there was still some deviation. However, there was only a fingerprint of the dead person on the dagger, indicating that the murderer was wearing gloves. According to the angle of the knife edge and the judgment of blood stains, it can be inferred that the height of the murderer is about 175."

Gu Yanzhi put his hands around his chest and looked indifferent: "about 175, so why do you want Zhou Nanlai to accept the record? She doesn't fit in, she doesn't have 175.
