Wu Hui got up and started investigating the case again.

This secret room case is quite troublesome.

Generally speaking, there are three ways to create a secret room. First, after completing the crime, the murderer forges the secret room and leaves the secret room. Second, after completing the crime, the murderer stays in the secret room and leaves with others after the secret room is opened. Third, he does not enter the secret room.

In a secret room, people rely on traps or poison to kill people.

Of course, these three methods are very unsafe and the evidence can easily be found.

After all, the secret room is a delicate thing. The more delicate it is, the easier it is to be destroyed. If you are not careful, you will leave evidence.

But in addition to evidence, players also need to analyze the modus operandi. If Wu Hui's tricks are clear about the modus operandi, but others cannot find the evidence. Then this case is like a murder case where the evidence may be found, but the modus operandi cannot be found.

Hard to find.

In addition, Xiao Ming’s case was difficult to find in the past. Wu Hui’s final crack was due to a lot of luck and scare factors.

It was really good luck to be able to find that eyebrow and scare Xiao Ming. There are a lot of hairs in the sports warehouse. I checked one by one and found Xiao Ming's hair within one day. What else is it but luck?

The criminal's level was so high, his style was ruthless and bold yet thorough, which made Wu Hui very suspicious that he was the Marquis of Snake Sword.

Of course, he couldn't see anything in the secret room in front of him for the time being.

The deceased was a woman living alone. She was lying in bed when she died. The cause of death was an overdose of sleeping pills.

The floor is on the seventh floor, and there are no signs of climbing on the windows.

The door is closed, and there is surveillance footage of the corridor at the door.

The sleeping (harmony) medicine was bought by the deceased himself. If it had been anyone else, it would have been treated as a suicide case.

However, it is impossible for the player to believe the theory of suicide when investigating the case. After all, if it is suicide, it is not a crime. The time of death was the morning of the 14th, and the last person to enter and exit the room was the best friend of the deceased who came to see the deceased on the afternoon of the 13th.

The name of the deceased was Xiaohong, 24 years old, single, at least on the surface, an ordinary company employee.

Wu Hui quickly identified the suspect.

First, my best friend. The last one to enter and leave the room, suspected of committing a crime.

Secondly, the landlord has the key and knows the condition of the house very well. He may have some special ways to get in and out.

Finally, Xiaohong's male colleague is said to be pursuing Xiaohong. But he was rejected many times. He was once seen saying that Xiaohong was ignorant or something, and he had a motive for committing the crime. And there was no alibi for the 13th and 14th.

.

Speaking of which, in a poisoning case like this, according to statistics, there is a high probability that the murderer is a woman. Men seem to be more inclined to commit violent crimes. But this cannot be used as evidence.

…

…

The 13th, morning.

Today is a big day, the day when I see my lover for the last time.

I brought her favorite red wine and came to her room. She looked into my eyes, a little sad, as if she had a premonition of something.

"Have you had insomnia recently?" I looked at the dark circles under her eyes and asked nonsense.

She didn't say anything, she just took the initiative to hug me and kiss me. I had just smoked a cigarette earlier and there was still a taste in my mouth, but she didn't dislike it.

It's so good, I can't bear to kill her.

…

…

The first thing Wu Hui checked was whether there were any other entrances and exits in the room.

Doors, balconies, windows. The doors are monitored, so it is impossible. There are no signs of climbing on the windows and balconies. If you want to go up and down on the seventh floor, you will definitely need to use tools.

In other words, regular entrances and exits are basically impossible.

If there is no secret passage, then we have to consider two possibilities: the murderer stayed at the scene after committing the crime, or the murderer did not appear at the scene at all.

Considering the poisoning and the fact that the deceased showed no signs of resistance during his lifetime, Wu Hui felt that it was more likely that the murderer did not appear at the scene at all.

There are many murders in the world that you don’t need to go to in person. An overdose of sleeping (harmony) pills... According to the situation at the scene, the deceased used red wine to prepare the medicine. What if the murderer’s medicine was directly inside the red wine?

But the red wine and sleeping (harmony) medicine were bought by the murderer himself. Hmm... It seems that the only one who had the opportunity to drug him was his best friend?

But the 13th was the last time that my best friend entered the room, and Xiaohong died on the 14th. And there is no evidence to prove that she did not commit suicide.

There are really few clues available, but if Wu Hui wants to be suspicious, he still has to suspect this best friend first. At the same time, check the communication records and chats of the deceased to see if there are any other suspects.

The suspect was identified, but no method was deduced and no evidence was found. Not to mention that the suspect was not legally established, Wu Hui himself did not recognize it.

I can only say that my best friend is the most suspicious at the moment.

The murderer must have entered the room, and the murderer and the deceased had a relatively close relationship.

Judging from all the suspects found so far, only the best friend meets this condition. However, there is no evidence, and the best friend still looks sad and gives a flawless confession.

That's why Wu Hui guessed that there were other suspects that he had not discovered.

Of course, it's also possible that his best friend is just acting with him. Wouldn't it be simple for the player's clone to act out a drama?

"There are no other people's fingerprints on the wine glass, nor on the medicine bottle. But that doesn't mean anything. Players have too many ways to remove fingerprints." Wu Hui rubbed his brows, "Are we going to pry into a confession again?"

He succeeded last time by luck. He wants to do it again this time? It doesn't feel very reliable.

"Let's start with the techniques... There is too little evidence at the moment. Then check the interpersonal relationships. Did the deceased usually drink red wine and take sleeping (harmony) pills?" Wu Hui suddenly thought of something.

Sleeping (harmony) medicine is not an ordinary drug. Because taking too much will kill you, it has always been a prescription drug. Therefore, you must have a prescription from a doctor before you can buy it. Ordinary people can usually buy some melatonin at most, which is not addictive.

It won't kill anyone.

Wu Hui found the doctor who prescribed the medicine, but the doctor denied that he had prescribed medicine to the deceased.

In other words, the sleeping (harmony) medicine was not bought by the deceased through normal channels. Did someone else buy it in the name of the deceased? Or what was she buying it for?

Of course, the police would have regarded this as evidence of suicide.

After thinking about it, Wu Hui turned back to find his best friend: "Did the deceased usually suffer from insomnia?"

…

…

Insomnia has always been a problem that bothers her. Faced with this question from her lover, she yawned: "It's okay."

"I bought you a bottle of sleeping pills, remember to take them." Her lover looked at her tenderly and put down the red wine: "Today is the weekend, do you have any plans to go somewhere?"

She tilted her head and thought for a while: "Well, why not go to your house?"

Go to my house? It’s best not to, you have to die in your own home. My lover didn’t say anything, he just smiled and said okay.
