Return to 1983 and be a detective

While Zhang and Ma were still investigating the scene over and over again, Xu Shan and the others arrived.

When he saw Xu Shan, Zhang Chengan's face dropped again: "Why are you coming back? Aren't you not cooperating with our work?"

Xu Shan was also quite helpless: "I am not the one who wants to come back. Director Zhang escorted me back again."

Hearing these three words, Director Zhang, Zhang Chengan was extremely angry: "That's nonsense, get out of here, or I'll sue you for obstructing official duties... Old Ma, handcuff him."

Before he finished speaking, he heard Zhang Mingwu's powerful voice: "Who dares?"

Hearing this voice, Zhang Chengan shivered, and then his eyes showed grievance and unwillingness: "Uncle... Director Zhang, why did you invite an outsider to help solve the case?"

Zhang Mingwu glanced at him and expressed considerable dissatisfaction with this guy's actions. "Assist? No, I asked him to teach you a lesson."

"He? He came to teach me? Why?"

"Don't ask why, just cooperate with Comrade Xu Shan's work honestly... Lao Ma, give Xiao Zhang the notebook and let him study hard."

Ma Yunfeng smiled helplessly and handed the work diary in his hand to Zhang Chengan.

Zhang Chengan took it angrily, poked it a few times with the pen, and said to Xu Shan: "Hurry up, don't waste everyone's time."

Xu Shan glanced at Zhang Cheng'an: "I don't know who delayed whom, Zhang Bureau, if you sincerely invited me to come to class, then I think there is no need to attend this class today. The students are not interested in listening, and neither is the teacher. I’m telling you, why don’t you let me go..."

Zhang Mingwu frowned at Zhang Chengan: "If you can learn, then learn. If you can't, don't be a policeman. Do you understand?"

Zhang Chengan was yelled at, but he stood at attention and replied loudly: "I understand."

Zhang Mingwu changed his face to a smiling face again: "Comrade Xu Shan, please forgive me, you are not only teaching him, but also teaching us. We are all your students. I hope you can give me some advice."

Reach out and don't hit the smiling man.

And Xu Shan didn't feel that at his level, he was really qualified to refuse Zhang Mingwu's request.

He could only sigh: "Okay, I'll try my best. But don't let this happen again in the future. If one person delays everyone for one minute, then I won't teach this class again."

He walked to Lan Qingping's body, took out a cigarette from his pocket, folded it into two pieces, stuffed it into his nostrils, turned around and asked Zhang Cheng'an, "Do you have any extra gloves?"

Zhang Chengan has a deep hostility towards Xu Shan: "Gloves? You're not a forensic doctor. What kind of gloves do you want? What are you pretending to be?"

Xu Shan glanced at him rudely: "That means there isn't one? Then why are you investigating? The dead body is the most important thing. In the end, you didn't even inspect the corpse. Isn't it just a show and wasting time in vain? ?”

The policeman named Xiao Song next to Zhang Mingwu took out a pair of rubber gloves and handed them to Xu Shan.

Xu Shan took it and put it on, stuffed the two cigarettes in his nostrils, clasped his hands together, bowed to Lan Qingping's body, and began to inspect the body.

"The deceased was a female, about 1.6 meters tall, with long hair... There were signs of rope strangulation on the neck of the deceased. It was initially inferred that she died of mechanical suffocation. The tools of the crime were unknown. The time of death was approximately between [-] a.m. and [-] noon. …”

As he spoke, he pinched the corpse's cheek and looked at her mouth. After this pinch, the blood in the mouth flowed out.

Zhang Chengan, who was watching on the side, could not help but frown, his stomach churning.Fortunately, he had taken general physical education classes at the Criminal Police Academy. Although he had never experienced a scene like this, he could still hold back from vomiting.

Xu Shan didn't care at all, and continued the inspection calmly: "Preliminary judgment is that the deceased had eaten before death. There were food residues in his mouth. What are you doing standing there in a daze? Quickly record it..."

After saying that, Xu Shan went down to check again. He checked very carefully, leaving Zhang Chengan on the side stunned.

Although he has also learned some forensic examination, it is only superficial. The Jinwu Public Security Bureau is different from the Longshui Public Security Bureau. The Longshui Bureau does not have a forensic doctor, but the Jinwu Bureau has a forensic doctor, so there is no need for him to do the examination.

Generally speaking, as long as he inspects the scene, gets the autopsy report from the forensic doctor, makes a comprehensive analysis, and then conducts an investigation. He has never seen criminal investigators conduct an autopsy in person.

"The deceased's abdomen was swollen and she seemed to be pregnant. Further anatomy is needed to confirm..."

Zhang Chengan reasoned while remembering: "Pregnant? Is it a murder of love?"

Xu Shan didn't answer his words. Anyway, this kind of reasoning was common to everyone and there was no particularly constructive conclusion, so he ignored it and took off Lan Qingping's pants.This move scared Zhang Chengan and quickly turned his head: "What do you want to do..."

"Of course it's an examination. An important step in the autopsy is to examine the private parts of the female deceased. Please, please be more professional. If you can't overcome this psychological barrier, how can you grow up to be a responsible detective? Well, the private parts of the deceased It seems that there are traces of life just now. Whether there are any bodily fluids left by the suspect need to be further extracted and sent for examination..."

Zhang Chengan recorded it one by one, and the more he listened, the more frightened he became. Then he became more certain: "I didn't run away. It must have been a love killing."

Even though he had investigated the scene so many times, while Xu Shan had simply conducted an autopsy, the information he got was vastly different.

He also felt some admiration in his heart. No wonder Zhang Mingwu asked Xu Shan to help solve the case. This guy did such a meticulous job.

But his admiration was only momentary. He thought disdainfully, I can do it just by working carefully.

Xu Shan poured cold water on it: "When inspecting the scene or obtaining evidence, you must not make any subjective assumptions, so as not to miss any information. If you have preconceived notions, it is easy to fall into the trap of the murderer. If you handle the wrong case, let the real culprit go, and arrest the wrong person, it will be a huge crime."

Zhang Mingwu has always been on the side. He is also an experienced criminal investigator. His ability to solve cases is quite outstanding, and he also has a set of experiences that he has practiced. However, his set of experiences can only be understood and cannot be expressed in words, otherwise he would not have to push himself. His nephew sent it to Xu Shan for guidance.

When Xu Shan said this, he couldn't help but nod his head and praised: "It's really well said. Indeed, many people tend to make this mistake. They have preconceived notions, just like suspecting a neighbor of stealing an ax, and surrounding themselves. If you speculate and look for evidence, you end up looking for evidence just to prove your speculation, and lose the original intention of solving the case."
