"Then you say, how did the murderer get into this house at that time?"

The monkey asked, lighting a cigarette.

Hearing this, everyone focused their attention on the scene, trying to deduce the murderer's situation from the clues.

I walked to the door and saw the answer, it was very simple, the murderer must be someone the victim trusted.

And there was a cup of water in the living room that had been drunk, when the victim's family was eating, and the murderer came to visit, and this glass of water was evidence of greeting guests.

Strangers, the owner of the house will not let him in easily, and I saw some soot from the ground, it seems that the conversation was very pleasant at the time, but I don't know why this tragedy happened later.

The scene is so immaculately preserved that almost no one has been in since the incident.

After sorting out my thoughts, I said, "First, find out who I am gay with Zhang Hai. Second, keep an eye on Nangong Lian, his girlfriend Nangong Lian, who was bisexual before his death, had a boyfriend and girlfriend, and now he can't find a boyfriend, so he can only keep an eye on his girlfriend. ”

Lin Yan'er said: "The murderer must hate the police very much, or the murderer hates the people of our criminal investigation team, find out if we have offended anyone?"

The monkey took over: "Who have you offended? Over the years, we have personally sent in not 1,000 but 800 people, how can we find out?"

Lin Yan'er said: "It's very simple, every time the case is closed, there is a great possibility that the person who shouts wronged, they may be really wronged, maybe they are falsely wronged, if he is really innocent, the first thing he will do after coming out is revenge." ”

The monkey nodded and said, "What you said will be done later, but the main thing now is to find evidence related to the suspect from this scene." ”

Kuroko took out a wide footprint lamp and a UV fingerprint explorer, intending to extract the murderer's footprints and fingerprints, and if he was lucky, he could even extract the murderer's DNA data from a hair and a cigarette butt.

After a circle, everyone's faces gradually became solemn.

The monkey had a gloomy face: "The murderer is definitely a policeman, he eliminated the fingerprints and footprints at the scene, leaving no clues, and even the cigarette butts he smoked were taken away by him, this case is a bit tricky." ”

The criminal investigation brigade is not omnipotent, and there are times when the murderer is very professional, maybe it was the police who committed the crime, and he knows in his heart the process of solving the criminal investigation brigade.

"What should I do?"

The man next to him furrowed his brows.

"If you don't have a clue, you have to find a clue for me. ”

The monkey said angrily, planning to stay at the scene all night, and he will never stop if he can't find a trace, as long as it is a human who commits the crime, then no matter how smart he is, he will leave some evidence.

Then I told them the conclusion of the previous investigation, as the saying goes, three stinkers beat Zhuge Liang, including the victim's conversation before his death.

After listening, everyone's legs were so angry that they kept trembling: "As a policeman, it doesn't matter if you don't cooperate to solve the case, you still conceal information, I don't think they want to continue to do it." ”

I signaled them not to be angry yet, saying, "It's okay to hide it alone, but the key is that everyone in the office doesn't want to solve the case." ”

In this way, we can't take those people, what's the secret in this, and let those police defend the murderer.

Who knew that they said in an almost roaring tone: "That means that everyone in the police station in that jurisdiction knows who the murderer is, and we don't have the slightest clue now?"

I nodded, so to speak, it was a public murderer, and almost everyone knew about it.

They defended this person, violated their pre-entry declaration, and were even more ashamed of the police uniform.

"The murderer has two identities, the first is a policeman, he has not yet been hired after a variety of training, if you want to kill, this will be an unsolved case, the second is a criminal, every crime can allow him to accumulate some experience, a habitual criminal, anti-reconnaissance ability is definitely not under the professional police. ”

Hearing the monkey say this, I nodded, "I'm more inclined to have the killer a police officer." ”

Before I could finish my sentence, the monkey looked at me, "Hmph, how can that not be a criminal?" ”

I smiled and said, "Would a person up and down the police station defend a criminal, rather than a colleague who has a deep relationship with him?"

"The murderer is in that police station, and what we need to do now is to find sufficient evidence. ”

These are reasoning that seem reasonable, but we all know that many cases are often reasonable and unexpected.

Until definitive evidence is found, these reasoning are nothing but fucking nonsense.

In one day, we found a total of several clues at the scene of the crime, which further confirmed our previous reasoning.

First, among the trembling marks around the table, a blue fiber was found, which according to the laboratory was a thread that had fallen off from the police uniform.

Second, the murderer was an acquaintance, and the victim did not have any precautions against him before his death, and the reason why there were signs of trembling at the scene may be that the murderer and the suspect had some quarrel behind him.

Third: After committing the crime, the murderer erased all traces that could identify him.

The third point is the most important point, the perfect crime scene allows us to confirm his identity, smart and confused, this simple question is ignored by him.

All that's left is for the county police to do it, and this crime scene has no value to us anymore.

Next, we visited the autopsy of the victim together, and on the way, Kuroko turned red and ran to the bathroom with a breath.

I resisted the vomiting.

The monkey's face was calm.

The forensic doctor who dissected the corpse, Ou Ye, chewed gum and blew a bubble out of his mouth from time to time.

The whole process was completely torturous for me, and when I saw the stitched corpse being re-cut one by one, there was always an indescribable depression in my heart.

Because the corpse was pounded three times and twice during the freeze, there was already some stench of decay, but it was not obvious.

"The biggest impression I had during the first autopsy was the hatred of the murderer at that time, I have also read a lot of reports on the deceased before his death, and I know some of the circumstances, it stands to reason that the family is approachable, and the murderer should not have such a big hatred?"

Ou Ye analyzed her own opinion while dissecting it, but she looked quite calm, as if what she was in front of was just a prop, and as long as she finished dissecting the corpse, she could get off work and eat.

"I did a DNA comparison of the hair in the child's belly, and the report was from one of the female corpses, which showed that the white dot was the mother of the child. ”

Ou Ye frowned, and when he dissected the boy's body, his face was a little unpleasant.

The murderer was completely inhuman, even the children were spared.

I don't know why such a perverted murderer still has anyone to shield him?

The monkey suddenly said: "The murderer should be a two-faced person, he has two personalities, just like we play with computers, he has a violent personality on the Internet, and he sprays when he sees unpleasant remarks, but in reality, a troll on the Internet is not good to say that he is a gentle and elegant doctor, an approachable employee." ”

"And that murderer may be a good guy in front of his colleagues and friends, but on the dark side he is a pervert. ”

I nodded and said, "I know all this, but have you ever thought that since you are a colleague, you must know him, and the person who shielded the murderer must know that the murderer has two personalities, but they still don't care about anything to shield the murderer?"

This case is a bit peculiar, the police committed the crime, and the whole office went to cover up the murderer.

"Ou Ye, can you analyze the extent of the damage to the corpse, how did the murderer pour strong sulfuric acid into the stomach of the victim without struggling?"

That's what I want to know most.

Ou Ye took a breath, raised the victim's hands and feet, and said, "Don't struggle? Who told you that the victim didn't struggle, and did you see the above binding marks? From the degree of bruises on the wrists and feet, it can be concluded that it was the wire that tied the victim's family. ”

"The victims were tied up with wire so that no matter what kind of pain the victim suffered, it was clear from the corroded cheeks of the corpses that the victims were struggling as hard as they could, but they could only twist their heads to the sides, so the sulfuric acid corroded the cheeks of the corpses. ”

"The murderer is a professional person, he has a strong psychological quality, do you say that ordinary murderers can calmly pinch the victim's mouth open and pour strong sulfuric acid without hurrying? There are a total of five corpses, that is, the murderer repeated five such processes, and in the process of the victim's struggle and begging for mercy, he looked at him coldly. ”

"It is impossible for such a person to be able to calmly clean up the traces of the scene afterwards without professional training. ”

Ou Ye's analysis sounds very reasonable, but I found a problem from her words, it is true that the traces of the first scene were cleaned up by the murderer, but this matter is only known to the five of us in the criminal investigation team, and no one has told her.

So how did she know that the traces of the first scene had been cleaned up by the murderer?

Seeing me looking at myself vigilantly, Ou Ye smiled and said, "The reason is quite simple, if you can find clues from the crime scene, will you let me dissect the corpse a second time?"

Ou Ye then added: "I suggest you go and stalk the victim's closest friend, who probably knows more than anyone else. ”

The monkey said, "Why?"

Ou Ye waved his hand to tell us not to waste time in the dissection room, and he only said, "Intuition." ”

There was no clue to the autopsy, and everything that could be found was issued in the first autopsy report, and it seems that if you want to solve the case, you can't just sit in the office and reason and analyze.

Even the autopsy report was reviewed many times, and in the end we were very disappointed, and the clues we could know were very limited.

As soon as they came out of the dissection room, the monkey and Kuroko trotted over with anxious faces.

Before I could speak, the monkey said with an extremely ugly face: "Nangong is in love with death." ”

For us, this news is no less than five thunderstorms.

The only clue is broken.

According to our logical thinking, the murderer deduced that we would start with Nangong Lian, so he killed Nangong Lian.
