Let you be a policeman and arrest the chief

Gao Yang analyzed, "If the reporter named Zhu Hongxue, then Zhu Hongxue probably wouldn't have time to escape or commit suicide. The criminal police team would also catch him. Of course, if he knew the news in advance, with his criminal investigation experience, he wouldn't have to commit suicide. And there is".

Gao Yang deliberately paused and said, "If a person wants to jump into the river, why get drunk? That will greatly increase the failure rate of jumping into the river. Especially since he is a criminal policeman, he can't drink alcohol on weekdays."

Cheng Zishan nodded when he heard this: "You mean, he didn't commit suicide?"

Everyone looked at Gao Yang, all showing a look of surprise.

If Zhu Hongxue didn't commit suicide, then how did he die?

Gao Yang waved his hand to deny: "I just made an inference. The case happened thirteen years ago, but after Zhu Hongxue's death, there were seven consecutive murders. The only evidence at the scene was him, a dead policeman. This is also the only direction for solving the case at present."

Zhang Tianfang held his head and asked puzzledly: "Why did the murderer leave Zhu Hongxue's fingerprints? Obviously not to frame someone."

Everyone looked at Zhang Tianfang with approval in their eyes, saying "You are so smart."

Zhang Tianfang also knew that he had said the wrong thing. He scratched his head and tried to save his image. "Of course it's not to frame someone. That would disrupt the direction of the investigation!"

Gao Dun shook his head: "With the anti-detection ability of this murderer, if he didn't leave any fingerprints at all, we would have no way to investigate."

Wang Mohan pondered; "Leaving fingerprints, or a dead policeman, there are only two meanings. First, Zhu Hongxue was wronged, and the murderer was provoking, or mocking the police; second, he wanted the police to investigate the cause of Zhu Hongxue's death."

Zhang Tianfang was stunned: "In order to let the police investigate the cause of Zhu Hongxue's death, he didn't hesitate to kill seven people? It's a bit of a fantasy, isn't it?"

Gao Dun looked at Wang Mohan approvingly, "Director Wang makes sense."

Zhang Tianfang still shook his head, saying that he didn't believe there was really such a person.

At this moment, Du Xiaoxi suddenly discovered something and said, "Three of the dead have criminal records? What about the other four?"

Gao Dun said, "It should be said that the first six are suspected of crimes to varying degrees. As for the seventh person, there is no evidence that she has a criminal record."

"If the first six are all suspects, then the murderer may be playing the role of the executioner of death to maintain the so-called justice." Wang Mohan frowned, "But who is the seventh person?"

Cheng Zishan interrupted at this moment, a little impatient: "You should take a look at the case file, the seventh is a teacher."

Gao Yang also saw it, "The deceased is Zhou An, a teacher at Jiangda, and he looks innocent."

Gao Dun nodded: "Yes, he was killed half a month ago, in the elevator of Jiangda, and no one saw how he got in."

"There is no surveillance?" Wang Mohan was puzzled.

Gao Dun nodded again: "Just like other cases, the murderer avoided surveillance and erased the traces of murder, but there are traces of oil at the crime scene, which is the same as other crime scenes: the victims died in different ways, poisoning, stabbing, strangulation, but there are Zhu Hongxue's fingerprints and a little oil at the scene, right in the center of the forehead of the body."

"Oil?!" Zhang Tianfang found the case more and more strange, "The fingerprints of the dead policeman, oil, what is the relationship between these two?"

Gao Yang looked at Gao Dun, who didn't say much.

Gao Yang thought for a while and said: "Since the last case is different from the previous victims, it is obvious that the murderer encountered a different situation. I think this is a breakthrough point."

Gao Dun agreed, "Director Gao, please help us. Our Yuhang Provincial Department will fully cooperate."

Gao Yang nodded: "Thank you, I want to see the body, the body of the university teacher named Zhou An."
