Conan: The Self-cultivation of Fake Wine

If his guess was correct, the murderer's method of killing was just like that.

The only discrepancy is the step of delivering the key to the deceased.

According to the nature of scientific cases, the murderer must have used some tool to accomplish his crime.

Throwing it directly would seem too reckless and lack technical skills.

So what would that tool be?

The distance between the air vent and the bed is four meters.

Could it be a stick that is thin enough and long enough?

Insert the stick through the air vent, place one end against the palm of the deceased, let the keyhole pass through the stick, and then slide the stick all the way to the palm of the deceased.

That's fine.

But this would definitely not withstand a search. The crime happened at four o'clock, and Maori and his friends got up at five o'clock.

The murderer could not destroy the stick in a short period of time, so even if he discarded it, he could only discard it nearby.

Because if the place where he abandoned the things was too far away and he couldn't come back in time, it was very likely that people would find out that he was not at home at that time.

This is a bit too suspicious.

Lu Ren is more inclined to believe that the murderer quickly returned to his room after committing the crime.

In this case, the murder weapon must be placed in the murderer's room, or simply on his body.

And it must withstand inspection.

Lu Ren then thought of something that might be used as a tool to commit the crime.

The wire inside a woman's bra.

If this is really the case, then the only female among the three suspects must be the murderer.

But...can the steel wire be that long?

This is nearly four meters long...

Lu Ren temporarily listed it as a backup option.

Or maybe the murderer doesn't have to succeed in one go as he thinks.

The murderer could actually try multiple times.

All you need is a magnet and a short piece of string.

Throw the key into the deceased's hand through the air vent. Even if it fails once, you can use a magnet tied to a rope to suck the key back and throw it again.

As long as there is a magnet in the deceased's home, you can just put the magnet back after the incident.

As for the rope tied to the magnet, it may not be a rope in the conventional sense.

It can be a four-meter-long string, and you can burn it with a lighter afterwards. You can eat the ashes left after the fire.

But if this is true, we must first confirm two points.

First, there really is a magnet in the deceased’s home.

Second, the murderer must have a certain degree of accuracy.

Even with the backup of a magnet, the murderer can make multiple attempts.

But the number of times is always limited.

The time for committing the crime should be as short as possible, otherwise something unexpected will happen.

Although it was four o'clock in the morning, there was a chance that someone might have passed by the deceased's house and seen a neurotic person standing at the air vent door in the courtyard.

If that were really the case, we would be doomed.

Not only does the accuracy in throwing the keys have to be high enough, but the accuracy in retrieving the keys and throwing the magnets also has to be high enough.

There are always other metal objects in the room.

If it is attracted by the magnet and makes a noise, then everything will be in vain.

Lu Ren thought this method was feasible, but for a newbie, the risk was still a bit high.

Lu Ren began to observe the entire crime scene again.

The deceased's bedroom is actually different from an ordinary bedroom. It is more like a room in a high-end hotel.

There are not only guest rooms and private bathrooms, but also a kitchen.

There is a coffee machine on the marble countertop in the kitchen.

Lu Ren walked closer and found that there was still some coffee liquid left at the bottom of the coffee machine.

It is believed that the deceased died of poisoning after drinking coffee mixed with potassium cyanide.

The situation at that time can be roughly divided into two types.

1. When the murderer knocked on the door and entered the room, the victim had not yet started making coffee.

2. The deceased had already brewed the coffee and poured it into the cup.

If it's the latter, there's only one way the murderer could poison the cup.

The former has an additional option, which is to poison the coffee machine.

But the risk of poisoning the coffee machine might be a little high.

For example, if the murderer made the coffee for the deceased, the deceased might invite the murderer to drink it together.

This is not impossible. There are a large number of cups stored in the storage cabinet above the kitchen.

Lu Ren remembered what Mao Li had just said, that the deceased had severe obsessive-compulsive disorder.

Then it is very likely that the time he drinks coffee is fixed.

The murderer calculated this exactly and chose this time to knock on the door.

There was a tray with coffee cups on the deceased's bedside table.

It is very likely that the murderer put the potassium cyanide into the coffee cup while it was still on the tray.

It's not difficult to do this.

A normal person would not open the door with a cup of hot coffee when hearing a knock on the door. Instead, he or she would put the cup on the tray at hand.

In this way, after entering the house, the murderer can find an excuse to distract the victim and easily poison him.

This method of killing does not leave many loopholes.

When you knock on the door, no fingerprints are left.

When poisoning, no fingerprints will be left because the hands will not directly touch the coffee cup.

After the deceased dies, it will be even less likely that he will leave fingerprints if he puts on gloves at this time.

The next step is to create a secret room. After leaving the room, lock the doors and windows, and throw the key into the hands of the deceased through the air vent.

It is not yet known what tools the murderer used in this process.

At present, the only flaw that exists at this stage is that the murderer put on the ring upside down in a panic.

There are two possibilities for this as well.

One is what Maori said, the murderer swapped the ring for money.

Lu Ren thought about it carefully for a while and felt that this possibility was not high.

Because real rings are hard to hide.

Whether it is placed in the room or on the body, it will easily be discovered by the police.

Of course, he could also have just thrown it in the yard, betting that the police wouldn't find it.

And even if they really found it, they would not be able to identify the suspect through the ring thrown in the yard.

Even so, Lu Ren still felt that it was not worth it.

Suppose the police really did not find the real ring at that time, allowing the murderer to succeed in his plan.

But how to sell this ring is another problem.

First of all, it is not the kind of ring that only has a large gemstone inlaid on the ring face.

This type of ring is easy to sell. Just remove the gemstone and sell it directly.

The deceased's ring was inlaid with a large amount of bricks and stones.

The moment you buy bricks and stones, their value quickly depreciates. You can't sell them at a high price.

Unless it is bricks and stones with a relatively large carat weight, the deceased's inlays are all made of broken diamonds.

It would be hard to sell the bricks and stones for much money, unless the murderer himself or someone very close to him was engaged in the jewelry processing industry.

It’s probably better to make it and then sell it.

If the bricks and stones are not removed, the entire ring can be sold directly.

The risk is too high and it is extremely easy to expose yourself.

Also, there is the ring that the deceased is wearing on his hand.

This "fake" ring is so well made that it is difficult to tell the authenticity with the naked eye.

The difficulty of imitation is naturally very high.

There are probably not many places in Tokyo that are capable and willing to do this.

By checking one by one, you can find the counterfeiter and learn from him who the client is.

Unless the client is not the murderer himself, but a stranger commissioned by the murderer.

He didn't know the murderer and didn't know why he wanted to customize the ring.

Or maybe the murderer had planned this many years ago and copied the ring somewhere else in Japan.

Wait……

Lu Ren realized something was wrong. "What does 100th mean? What does it represent?"

The curly-haired female editor replied, "This is Mr. Zhukou's work in commemoration of his 100th work."

"Just finished writing it?"

"Ah."

"So the ring was also custom-made not long ago?"

The curly-haired girl continued to nod.

Okay, the plan made many years ago can be passed.

If the ring was switched, the killer either had to use a middleman or have a jeweler with whom he had a good enough relationship to ensure that he would not betray him.

As for the former, Lu Ren felt that the murderer probably didn't have the brains to do that...

The latter just needs to check the interpersonal relationships among the three people.

In general, the total value of the ring is not high. And from the whole process of imitation to disposal, the risk is still quite high.

Add to that the risk of murder, and it's really not worth it for a ring like this.

So in Lu Ren's opinion, although the possibility of package substitution exists, it is not very high.

At this time, we have to consider the second possibility: the murderer did not switch the ring, he just took the ring off the victim's hand for some purpose and put it back on.

In the process, he accidentally put the ring on backwards.

Lu Ren looked at the body shape of the deceased. Mr. Zhukou was a little fat, with a big belly and short and thick fingers like carrots.

Especially the ring is not removable.

It is not easy to take the ring off your hand. It will be quite strenuous.

Therefore, the murderer must have had some special purpose in taking the ring off the victim's hand.

It is not enough to take it off, it is put back on the deceased.

Lu Ren took off the ring on his hand and put it back on again. He tried to understand why the murderer did this by repeating the process.

First of all, it can be confirmed that this behavior has nothing to do with the method of murder or poisoning.
