Let you be a policeman and arrest the chief

After hearing that the only evidence at the scene of the seven murders was the same fingerprint, whose owner had died, Wang Mohan, Zhang Tianfang, and Ma Weiqiang looked at each other in bewilderment.

Zhang Tianfang wanted to speak, but Wang Mohan stopped him.

After all, this group represented the Longjiang Provincial Department, and Zhang Tianfang's head was full of mud. He couldn't embarrass himself in front of outsiders.

Family disgrace should not be made public.

Although Ma Weiqiang was born a gangster, he has matured a lot now. He analyzed: "Is it confirmed that it is the same fingerprint?"

Cheng Zishan rolled his eyes at Ma Weiqiang and straightened his back, but it was obvious that he had a herniated disc on his waist. He quickly held his waist and said: "Humph, are you questioning my professional level?"

Ma Weiqiang said no, Cheng's forensic doctor's skills would never be wrong.

"Humph, you can say it. You are a Longjiang policeman, you don't know me at all," Cheng Zishan said, but his face looked much better.

Gao Dun said helplessly: "Old Cheng, our colleagues from Longjiang are here to assist us."

Cheng Zishan stopped talking, but he was obviously not convinced.

Ma Weiqiang coughed and said: "Since it is the same fingerprint, that is to say, the murderer has kept this fingerprint for a long time, and then kept putting it at the crime scene, then what is his purpose? I mean, who is the owner of this fingerprint? Is it worth the murderer to go to so much trouble?"

Wang Mohan also coughed, and Ma Weiqiang finally asked a question that was a bit nutritious, but he looked at Cheng Zishan, "Director Cheng, I think the owner of this fingerprint died abnormally."

Gao Dun looked at Gao Yang, probably thinking that among your subordinates, only this person is more reliable.

Gao Yang smiled slightly, Wang Mohan is indeed Gao Yang's number one general.

It's not that the others are not good, but their skills are in other aspects.

Cheng Zishan nodded gently, because he saw that Wang Mohan was a big shot, and said, "Yes, a policeman."

"Policeman?" Wang Mohan asked in surprise, "How did he die?"

Gao Dun said, "He jumped into the river, the Qiantang River."

Gao Yang knew that the Qiantang River tide entered the sea at Yuhang Bay.

Then, Gao Dun recalled with a tone of recollection, "His name is Zhu Hongxue, the deputy captain of the criminal investigation team of the Qiantang County Bureau. He was investigated for suspected rape, but he committed suicide the night he was summoned."

Du Xiaoxi frowned, "But after his death, his fingerprints appeared at the scene of the serial murder. Why?"

Cheng Zishan said unhappily, "If we knew why, we would have caught him."

Forensic doctors are generally a bit weird. After all, they face corpses every day, and forensic doctors are indispensable for police to solve cases, so everyone tolerates it.

But Du Xiaoxi's personality is not tolerable. Because she was also a forensic doctor, she shrugged: "I don't know, you are so confident, Old Cheng, your ability is all in the lumbar disc protrusion, there is nothing protruding on the neck."

Cheng Zishan was furious, "My lumbar disc has nothing to do with my ability! Besides, who are you, a yellow-haired girl with hair that has not grown out yet."

Du Xiaoxi sneered: "You don't even know whether it has grown out yet, you went to the junior high school physiology and hygiene class for nothing."

Gao Yang coughed and stopped the two people from bickering.

Du Xiaoxi looked at Cheng Zishan with disdain, and the latter sat down angrily, tilting his head and not looking at Du Xiaoxi.

Gao Yang smiled: "This is Du Xiaoxi, the director of the Forensic Department of the Longjiang Provincial Department. She is the same as Director Cheng, and we are in the same industry."

Cheng Zishan was stunned, and then puzzled: "Her? A director-level forensic doctor?"

Du Xiaoxi snorted: "Yes, a director-level or not, the key is good technology."

Wang Mohan looked at Gao Dun: "Director Gao, this Zhu Hongxue seems to be the key to the case. You must have investigated his crimes."

Gao Dun was in no mood to joke. Obviously, this case put a lot of pressure on him. He nodded; "Zhu Hongxue was in a serious drunken state when he jumped into the river. There was no external injury, and the water in his stomach was consistent with drowning. He was accused of raping a girl in the boarding school, and before that, someone did report that a girl in the boarding school was sexually assaulted."

Du Xiaoxi held her chin, "Minor?"

Gao Dun nodded solemnly.

Du Xiaoxi angrily asked, "Did this Zhu Hongxue do it?"

When it comes to evidence, Cheng Zishan couldn't help but say, "The DNA information extracted from the girl's body matches that of Zhu Hongxue."

Zhang Tianfang added, "So it was him? Then it would be natural for him to jump into the river. After all, a second-in-command of criminal investigation would be ashamed to do such a thing. Suicide would be reasonable."

Gao Yang waved his hand and turned to Gao Dun, "Did the person who reported the case at the boarding school say who sexually assaulted him when he reported the case?"

Gao Dun nodded, "Yes."

Gao Yang pointed to the file, "But this person is not Zhu Hongxue!"

Gao Dun was stunned. This file did not record it. He blurted out, "How do you know?"
