Let you be a policeman and arrest the chief

Gao Yang packed up his things and prepared to guide the Qiantang serial murder case.

He knew that this case was very difficult because the murderer had been killing people for thirteen consecutive years, but there were few clues so far.

The vice governor and director of the Public Security Department of Yuhang Province was called Gao Dun, who was Du Dayong's classmate and good friend.

Du Dayong told Gao Yang that Gao Dun was a reliable person and he would try his best to help Gao Dun solve the case.

However, Du Dayong also said that this case was very unusual.

Back then, the murderer killed six people in a row and disappeared.

This time, the murderer was silent for a few years and appeared again, killing people again. Now is the Internet age, the news spreads very quickly, causing a sensation across the country. Gao Dun had no choice but to find Du Dayong.

Du Dayong asked Gao Yang for his opinion and warned Gao Yang that this case was a big unsolved case.

"Why do you say it is an unsolved case? And you have to add a big word?" Gao Yang instantly became interested.

Gao Yang was slightly surprised by Du Dayong's words. Du Dayong said in a serious tone: "Because the only murderer has been ruled out as a suspect."

This is what Du Dayong told Gao Yang, and Du Dayong also said: "If you are not sure, you can choose not to go. If you can't solve the case, your reputation as a detective will be ruined."

Gao Yang became more interested.

Given the degree of trust Du Dayong has in Gao Yang, he actually said such "disheartening" words. It can be seen that this case is indeed difficult.

Therefore, Gao Yang must go.

But before leaving, I don't know how Du Xiaoxi got the news and insisted on going.

Her reason was to exercise. She wore a sweetheart collar sweater and said to Gao Yang gently: "I heard that there are many beautiful women in Yuhang, and they are as gentle as water. I want to learn how to be gentle."

Gao Yang originally refused, but when he thought about handling the case locally, how could he do it without his own people.

Although Du Xiaoxi is lustful, she is only good at her own lust after all, and she is good at forensics and physical evidence investigation.

So Gao Yang applied to the ministry and brought Wang Mohan, Zhang Tianfang, Ma Weiqiang and Du Xiaoxi with him.

When they arrived at the Yuhang Provincial Department by plane, Director Gao Dun personally greeted them.

Gao Dun was tall and strong, handsome and very capable. It was said that his father-in-law was the top leader in Lin'an, a vice-ministerial level official.

Gao Yang saw at a glance that Gao Dun was also an expert.

"Welcome Director Gao. We've been waiting for you!" Gao Dun shook hands with Gao Yang, "Do you want to take a break or go straight to the case?"

Gao Yang waved his hand: "Just investigate directly."

Du Xiaoxi smiled: "Director Gao, you look very anxious."

Gao Dun asked everyone to sit down, then glanced at Gao Yang and then looked at the others.

Gao Yang knew that he was worried about inconvenience, so he said: "Don't worry, they are all my people."

Gao Dun nodded, "Director Gao, you are a criminal investigation expert in the department, and you are well-known. I won't say that I admire you. You should have heard about this case."

Gao Yang said: "It's just a part. I heard that it is a serial murder case, and the only suspect has been ruled out?"

Hearing Gao Yang's somewhat contradictory words, Gao Dun smiled bitterly, "You can say that. The file is here, take a look first."

Gao Yang took the file and quickly browsed it.

Du Xiaoxi came to Gao Yang and frowned: "In the past thirteen years, a total of seven people were killed? The last one turned out to be a NPC representative?! No wonder the public opinion was so strong. But is there only so much in the file?"

As he was talking, there was a knock on the door, and a middle-aged man wearing glasses came in. He had messy hair and wore a white coat. He was obviously a forensic doctor.

Although Gao Dun was the director, he stood up when he saw this person and said, "This is the director of the provincial department's forensic department, Cheng Zishan. He is the most experienced forensic doctor in our province. Old Cheng, please introduce the situation."

Cheng Zishan said with the arrogance and calmness unique to forensic doctors, "Who is Director Gao Yang?"

Gao Yang stood up and smiled, "I am."

Cheng Zishan frowned, a little surprised, but concealed it well, saying, "Director Gao is younger than I thought, but you are famous, I think you have already seen it."

Gao Yang nodded and told the information he saw: "Seven people were killed, but there was no physical evidence at the scene. The murderer avoided all surveillance and his anti-reconnaissance ability was top-notch. There is no human evidence, but..."

Gao Yang paused.

Du Xiaoxi pointed to the conclusion on the file and whispered, "But the same fingerprint was left at the scene."

Zhang Tianfang was confused: "This solves the case. Although it is very troublesome to check fingerprints."

Du Xiaoxi shook his head, showing a deep confusion: "But the owner of this fingerprint died thirteen years ago."
