Early that morning, after Xiao Su and I first came to the police station, before we could enter the office, the captain called and issued an order: set off collectively, there is a murder case......

After arriving at the scene of the crime, I saw that a cordon had been set up in a vacant lot on the outskirts of the city, and several forensic and forensic doctors were stepping on the deceased in a car and conducting an autopsy on the spot......

Xiao Su and I hurriedly went to inquire about the situation.

"Chief, deceased, male. His name is Bai Peng, he is 36 years old, he is the owner of this car, and there is a driver's license and some registration information of the vehicle in the car. The temple area was hit continuously by a hammer-like metal object, and he died of bleeding to death in the back seat of the car. There was no money in the car or on the deceased. According to the forensic measurement of liver temperature, the time of death was between 11 o'clock last night and 2 o'clock this morning. Xiao Su briefly reported the situation at the scene to the captain.

I found a piece of grass on the deceased's clothes, which looked very special, so I asked my colleague who stepped on the certificate to put the grass away......

According to the past practice, Xiao Su's report is just a routine. And often after Xiao Su reports, the captain usually says: Collect the team, go back to the meeting to talk about the case!

Sure enough, after listening to Xiao Su's words, the captain was silent for less than five minutes, and said: "I can't find anything at the scene, close the team and go back to the police station to talk about the case." ”

After hearing the captain call for the team, I began to sort out some of the details I had just observed......

After returning to the police station, they began to meet again to discuss the case.

In the conference room, Xiao Su said: "I have checked, the deceased was an ordinary black car driver, and he usually relied on this southeast car that he bought for 20,000 yuan and did not know how many hands he had, and no money or property was found on the deceased or in the car, which shows that it was obviously a robbery and murder." Normally, the murderer will get on the bus in the form of a taxi, and then wait for the car to drive to a remote place and do it directly. ”

After Xiao Su finished speaking, the captain nodded and said, "Very good, Xiao Su, you have been improving faster and faster recently." The analysis is completely consistent with the captain's thoughts, but anyone can see such a simple scene, what we have to do is to find the murderer and solve the case. ”

I listened to the words of the captain and Xiao Su, frowned and said, "Boss, I'm afraid it's not that simple, right?" This time it shouldn't be a simple robbery and murder. ”

As soon as I finished speaking, the captain shouted to me, "Can you change your problem, you always don't say everything, and if you have any different opinions, just say it." You're going against others. ”

After I listened to the captain's words, I said to him, "The scene is not a crime scene at all, but a scene of abandoned corpses." ”

As soon as my words fell, Xiao Su interjected and asked, "How can you be sure that it is the scene of the abandoned corpse?" ”

I smiled and explained to her: "The driver died in the back seat, but I observed at the time, and there was no sign of a fight around the car, as evidenced by the report. This shows that the murderer put the deceased in the back seat after the murder, and then the murderer himself drove the deceased to the outskirts of the city. Also, I watched the last count of the dashcam in this car, which showed 20.9 kilometers, and I think that somewhere 20.9 kilometers away from where we found the deceased was the real first crime scene. ”

After I finished speaking, Xiao Su lowered his head and thought about something, and the captain also fell into his pretended meditative state......

After a short time, the captain said: "I seem to understand a little, you mean that the kilometers of the dash cam can be used to calculate where the murder scene is?" ”

I smiled and nodded, "Well, it's as simple as that." But the range is a bit wide, after all, we don't know where this 20.9 kilometers is, so if you check it comprehensively, I'm afraid it ......"

Before I could finish speaking, the captain interrupted me: "Okay, don't be afraid, you can hurry up and count 20.9 kilometers." ”

When I heard this, I immediately asked, "Am I counting?" ”

The captain lit a cigarette and said to me, "Aren't you talking nonsense, don't you pay me back?" If you are a newcomer, you have to teach you according to your aptitude! Go ahead. ”

The captain adjourned the meeting, and I could only do arithmetic in my office......

20.9 kilometers is not a long distance, but the earth is round, and I don't know which direction it is in.

Just when I couldn't determine which direction, Xiao Su came in with a report and said to me: "Here, the grass you gave them is a kind of alfalfa." It is mainly an additional nutrient made into animal feed, which is used to feed livestock. ”

After listening to this, I thought for a while and said, "Aren't all alfalfa grown in the mountains?" How could it be possible for the deceased to have this thing on them? ”

After listening to my words, Xiao Su thought for a while and said, "Yes, the deceased was found on the outskirts of the city, but there is no mountain near there at all." It seems that there are no mountains according to what you said about 20.9 kilometers. ”

After Xiao Su finished speaking, I seemed to think of a little, so I immediately turned on the computer and began to search for livestock farms within 20.9 kilometers of the scene where the deceased was found......

It didn't take long for me to find out that there were three farms in the search area. Xiao Su looked at my search results and said, "You mean to assume that the first site is in the farm?" You found it out on the Internet, but what if there are some small farms that you can't find? You can't go looking for it on your legs, can you? ”

As soon as Xiao Su finished speaking, I shook my head and said to her: "The deceased was a black car driver, and it is impossible to go to the farm for no reason." In this way, don't you know the background of the deceased, you go and check the social relations of the deceased, and see if there are any people who are related to the farm. ”

After Xiao Su heard what I said, he looked at me with eyes and said, "Why did I go to check?" Why are you going? ”

I smiled awkwardly and said, "Work hard, I've been doing math problems all afternoon, and my brain is so tired." Just let me relax. ”

After Xiao Su pinched me the waist, I went out to investigate the deceased's social relations. And I was overused by my brain, so I was ready to make up for it in the office......

After a few hours of investigation, Xiao Su came back to me and said, "Do you see if there is a Beichen Farm in your search area?" ”

As soon as I finished listening, I turned on my computer. Sure enough, within 20.9 kilometers of the discovery of the deceased, there was indeed a Beichen livestock farm. Since Xiao Su said the name of this farm, it seems that there must be something wrong with this farm. Xiao Su and I are going to go to the farm immediately to investigate......
