Return to 1983 and be a detective

Just when Xu Shan was looking for Mr. Zhou while taking over his property, a major case occurred in a small county in Linzhou.

The case was relatively simple. The house where a family of five people lived was locked and then set on fire.

There were old people, children, and pregnant women in this house, and eventually they all died.

It can be said to be very miserable.

The impact was also very bad, and the superiors quickly assigned the case to Long Shui Criminal Investigation.

The explosion case in Longshui Criminal Investigation's own building has not been solved yet. For the time being, everyone can only work in the temporary house prepared by Xu Shan.

In front of a whiteboard, Xu Shan began to draw a guide for everyone.

Nowadays, the maps used by everyone to analyze the case are unified and standardized, and everyone can understand them clearly at a glance.

After Xu Shan finished the painting, he continued to analyze: "There are several doubts about this case. First of all, the house was locked and the fire was outside, but there seemed to be no trace of anyone passing by outside. And the family of five who died , usually be kind to others, and don’t even have any enemies. Another thing is the identity of this family. It is said that they are just tea farmers who grow tea in the village, but they have moved to a small courtyard with a single family in the county. How did they get their money. "

Li Yanzi immediately asked: "So Master Xu, what you want is for us to investigate separately. One is to investigate the financial sources, the other is to investigate the interpersonal relationships, and the other is to look for the ignition point to see if there are any arsonists left behind. Traces?"

Xu Shan nodded: "Yes, that's what it means. We are going to divide our troops into three groups now. There are eight of you, plus one of me, which is exactly nine people. Let's just share one point. Who wants to join my group? ?”

The members of the new eighth group rushed to raise their hands, and everyone wanted to be in the group with Xu Shan.

Xu Shan coughed twice: "Don't rush to grab it. My main focus now is on the explosion case in our criminal investigation building, but I don't have much energy to investigate this arson case."

"Master Xu, please don't underestimate yourself. Although we are now able to stand alone, we still have many ideas that we haven't caught up with. I hope to get some guidance and inspiration from you." Su Jing said.

Others agreed.

Xu Shan felt a little helpless when he saw them like this: "Well, I really didn't expect that I am so popular. In this case, I will just name them, Ma Qing, Gu Dahai, you two follow me to investigate the source of the fire. As for the other six people, you are divided into groups, one is to investigate interpersonal relationships, and the other is to investigate financial sources."

Soon the Xinba Group followed Xu Shan to a place called Kaibing County in Lin Province.

This place is also a small county town under Xiyang. The place is small and the county town is not big. It belongs to a mountainous area.

The county is small and has a small population, so there is a nursery rhyme left from ancient times: A small Kaibing County, two tofu shops, a spanking in the city can be heard outside the city.

Although it is now a period of rapid economic development, due to the limited geographical location of Kaibing County, it is far inferior to Longshui.But the more people live in a place like this, the more honest they are.

After everyone arrived in Kaibing County, they immediately launched an investigation.

Xu Shan was different from the others, but he took Ma Qing and Gu Dahai to eat all the snacks in Kaibing County.

What kind of steam cakes, fried green snails, and clear water fish? The two of them were a little doubtful about life.

Ma Qing kept asking Xu Shan: "Master Xu, they are working hard to investigate the case there, but we are here eating and drinking. Is this really okay?"

Xu Shan glanced at him: "What do you want to express?"

"I mean, should we also investigate the case?"

Gu Dahai on the side also nodded repeatedly. He also looked forward to learning from Xu Shan, but Xu Shan didn't seem to be anxious at all.

Didn't he say that he still had to solve the explosion in the criminal investigation building?Why doesn't he seem to be in any hurry now?If he was not in a hurry, the other two would be so anxious as if the emperor was not anxious and the eunuchs were anxious.

"You don't understand," Xu Shan leaned lazily on a chair in the hotel, "I am actually leading you to solve the case now."

"Can this be called solving a case? Master Xu, I don't have much education, so don't lie to me."

Gu Dahai was very puzzled.

Don’t lie to me because I don’t have much education. In fact, it’s just something Xu Shan brings out when he talks.

"Look at you, do you know what haste makes waste? What is the most important thing in solving a case? In fact, it is to have a normal mind. The more nervous and anxious you are, the more often you miss some things. And we The things being investigated are actually related to fire, and the focus is on investigating the source of the fire. Let me ask you, what was the ignition substance at the fire point at the scene?"

"Isn't it tea oil?"

"Yes, it's tea oil. Think about it again, what is tea oil used for?"

"Of course it's for cooking."

"Then what are the characteristics of the hotels we are looking for now?"

"They all seem to be restaurants that cook with camellia oil."

"That's right. Generally speaking, we use rapeseed oil for cooking. This thing is relatively easy to obtain. Just grow rapeseed. As for camellia oil, it takes a long time to grow tea seed trees, so generally speaking, we use camellia oil for cooking. There are still relatively few places.”

"No wonder, I heard you keep asking the boss where you bought the oil. Are you trying to find out the origin of this camellia oil?"

"exactly."

"But you can just call them over and ask them. It seems very inefficient." Ma Qing was puzzled.

"Efficient? No, no, I am not pursuing efficiency. You must pay attention to this in your work in the future. Although we do pursue efficiency in solving crimes, we must not use this as the goal. In the process of solving crimes that pursues efficiency, Among them, it is easy to make your own omissions, which will lead to unjust, false and wrongful convictions. This is a stain that our criminal investigators will not be able to wash away for several lifetimes. It can be said that even if you solve a thousand major cases, you will end up arresting the wrong one. If you kill one person and cause an unjust, false or wrongful verdict, then the merits of these thousand major cases cannot be equal to this wrongful verdict."

Ma Qing and Gu Dahai rarely saw such a serious Xu Shan, and they couldn't help but feel shuddering: "Master Xu, let's remember that we will never let go of our normalcy for the sake of efficiency. But let's get back to this case. Secondly, is the source of camellia oil really so important? Couldn’t it be that they squeezed it out from the oil mill themselves?”

Xu Shan glanced at the two people: "Yes, that's it. I was just asking about how many oil mills there are in Kaibing County. Now the results of the investigation have come out. There are three oil mills in Kaibing County, all tea seed oil They all come from these three oil mills, now let’s go to these three oil mills and take a look.”
