According to the conclusion of the preliminary autopsy at the scene, the nature of this case is infinitely close to love homicide, so it becomes particularly important who the deceased had emotional entanglements with during his lifetime.

Lin Zifan had already learned about the family situation of the deceased Bai Chuyue, and had a preliminary understanding of Bai Chuyue's social relations.

"Does Bai Chuyue have any emotional entanglements?" Lin Zifan suddenly asked.

Bai Chuyun hadn't recovered from his sister's murder yet, and looked at Lin Zifan with some sneer.

"Whether it is before or during marriage, or after the death of her husband, does anyone pursue Bai Chuyue?" Lin Zifan accentuated his tone and asked again.

Under Lin Zifan's repeated questioning, Bai Chuyun retrieved the answer to the question in a blank brain.

She opened her blank eyes, looked at Lin Zifan in a daze, and said slowly: "It seems that the supermarket manager she works for is very good to her, but if she is not pursuing her, I don't know." ”

Looking at Bai Chuyun's current state, she couldn't ask any valuable clues, so she could only investigate and inquire here for the time being, and then re-investigate her after her emotions gradually stabilized.

A large number of clues were found at the scene, and after we conducted an on-site investigation, we returned to the bureau with a large amount of physical evidence, and various departments immediately carried out inspection work.

In the office of the Serious Crime Unit, we immediately held a meeting to analyze the case.

Gushui Town is a quaint town, and almost all of the town's residents live here. The people are simple, every family knows each other, and the relationship is very good.

Now, there has been a serious homicide in Gushui Town, which has spread for a while, and the social impact is extremely serious, and the residents of Gushui Town feel that everyone is in danger.

As long as everyone mentions this murder, they will have a chill down their spines, and everyone will not dare to go out at night, and the doors and windows will be closed. For a while, Gushui Town, which was extremely lively, turned out to be crowded.

This not only has a serious impact on the psychology of the people, but also forms a serious obstacle to the normal operation of Gushui Town in all aspects.

The burden on our shoulders is immensely heavy.

"In this homicide case, the murderer's methods were very cruel, using a fruit knife to connect the deceased with more than ten knives, and then stabbing him in the lower body, the nature of this case is likely to be a love killing." I spoke slowly, presided over the case analysis meeting, and spoke first.

Lin Zifan nodded, and immediately added: "The deceased's sister Bai Chuyun said that the deceased Bai Chuyun was introverted, weak and timid, never quarreled with others, and had no enemies outside, so vendetta can be preliminarily ruled out." At the scene of the crime, there were no traces of the deceased's home being rummaged through, and the deceased's mobile phone, cash, gold and silver jewelry were not lost. ”

"The murderer used a fruit knife to stab the deceased continuously, which was enough to cause death. The murderer also used a fruit knife to repeatedly stab the deceased's lower body, which is an act of revenge, and the murderer and the deceased must have emotional entanglements. Li Meng also very much agrees that the nature of this case is a love killing.

"The police said that when she came to the scene of the crime, the gate was hidden, and after the on-site investigation by the technical team, there were no traces of damage to the doors and windows, and the murderer entered through the gate, and it should be an acquaintance who committed the crime." Xue Hang said lightly.

Based on the search found at the scene of the crime, we have summarized and have an obvious framework understanding of this case.

As long as the person who is emotionally entangled with the deceased is found, with the assistance of DNA and other biological samples, the murderer can be locked.

At this moment, Lin Zifan suddenly frowned and mentioned a past incident to us: "Do you remember the serial murder case of a bar man we solved before?" The murderer also smashed the deceased's lower body after the killing, which is also an act of revenge, but the victims are all men. ”

I pondered for a moment, slowly raised my head to look at him, and asked seriously: "So you suspect that this case may be a random murder by the murderer?" ”

Lin Zifan nodded and said to us: "It is very likely that the murderer has a specific standard for his target, and it was raining heavily on the night of the crime, and there was a power outage, so it is very likely that he pretended to be a circuit maintenance worker and broke into the house to kill people." ”

"But how to explain the cigarette butts left at the scene? It can't be that the deceased smoked it himself, we didn't find any cigarettes at the scene of the crime, not even the lighter and ashtray. And the sister of the deceased also said that the deceased was a non-smoker. Xue Hang thought about it and expressed his opinion to him.

Until there are sufficient clues and evidence to establish the nature of the case, either case may be the truth of the case.

And this case does have the same murder modus operandi as the bar serial murder case we solved before, and the murderer also carried out a crazy revenge attack after the killing.

But can a murderer really break into a house and kill someone?

After pondering for a while, Li Meng was very puzzled, she took over and said in a deep voice: "Although the two cases are somewhat similar, I think this case is very different. According to criminal psychology, if the murderer is hostile to a type of person and has the idea of killing, then it will most likely be a serial murder. Every time a murderer kills someone, he will have a great sense of accomplishment and satisfaction in his heart, and this psychology will drive him to continue to commit murder. ”

Li Meng paused and continued: "The core of the serial murder case is whether the murderer can complete multiple crimes before being caught by the police. Therefore, after committing the murder, the murderer of the serial murder will carefully clean up the scene to ensure that he does not leave too many clues for the police, and only this time, the murderer can continue to kill. ”

Xue Hang nodded, and let out a somewhat puzzled voice: "At the scene of the crime this time, there are too many clues left by the murderer, and almost all of them have appeared at the scene of the crime." But I always find it a little strange, even if the cigarette butts and footprints were left in a hurry, why did the murderer leave the murder weapon fruit knife at the scene of the crime? ”

Xue Hang's words went straight into my heart, and I always felt that this matter was a little strange.

After being silent for a long time, I suddenly said, "Have you noticed that there were only cigarette butts at the scene of the crime, and no ashes were found?" ”

When we heard this, we all turned our eyes to me.

"The deceased did not smoke, so there was no ashtray at home, so this cigarette butt could only be left by the murderer. If the murderer smoked at the scene of the crime, whether it was before or after the killing, he would definitely leave traces of cigarette ash. And it was very good for the murderer to leave the cigarette butt at the scene of the crime, so ...... said, "I said and didn't continue.

Because this is just a doubt, how to explain this doubt, I haven't thought about it for the time being.

"Therefore, it is very likely that this cigarette butt was not left by the murderer, and a total of two people entered the scene of the crime on the night of the crime." Li Meng suddenly spoke.
