Theory on the shrinking effect of APTX4869

[jimmy_kud0_tv2]

(I don't recall if her cause of death was established)

It was not. Both were ruled as "unclear". However there were clear signs of struggle in Kouji's case. (File 948)

Besides, as we've seen, he forgets the names and faces of those who's killed so he forgot about Shinichi a long time ago.

I had forgotten about that part. How come you remember all of this, But yeah, Gin CONSIDERED shinichi to be dead, hence left him. But since we don't know what happened 17 years ago, everything is just a theory, who knows Rum was send to kill Kohji becuase he refused to give "Protection Money" which the Organisation asked. And while killing him, Amanda interrupted and he killed her as well knowing the fact that she had ties with FBI and CIA, and had seen him then and there killing Kohji.

There are a lot of things in that case that don´t make much sense.
First Amanda goes to Kohji´s room, they have a cup of tea and a snack, then se returns to her room and dies, while Kohji is assasinated too in his room.

We don´t even know if Amanda was meant to be killed.
Actually, she might passed away naturally, she was really old after all. Although all indicates she was murdered by Rum.

But...who was murdered in first time¿? By logic it should be Amanda because killing her after escaping of Kohji´s room it´s really
improbable.

First, the police report stated that both Amanda and kohji's death was caused by "unknown" reason (natural death isn't unknown reason).
Second, Kohji was in the list of APTX.
Third, Rum involved in that case.

Isn't that mean RUM used APTX/Silver bullet?

Considering both of victim condition... Amanda was death with no external wound and Kohji had a lot of bruise in his body... so, i suppose Amanda died first.

@tantei san
i mean she only know that while she was checking kudo's house... After she saw that Shinichi's kid cloth was missing. Then it can be explained why she changed his status in the list as "death" because at least she already have some thought about shinichi's shrunken body. If you read the conversation between ai and shinichi in manga vol 18 (sorry i don't know the number of file it is... Because i'm not read the DC in internet except the recent volume) You will know what i mean if you read Ai's deduction about shinichi.

A random stupid idea, what if Rum gave the drug to Kouji and he shrank instead of dying, and became his btother Shukichi? Or took his identity. And now he lives normal life undercover.

I think you forgot, Kohji's body was found by the police, and since he was on the APTX list, means even BO confirmed he was dead. So, your idea is random and stupid

I don't have a lot of facts to back up the theory, but I think the shrinking effect is tied to Conan's blood type. Conan has a blood type of AB-, which is pretty rare, just like the shrinking effect of APTX4869. And yes, that is all that this theory is based on and yes, I am aware it's nothing but one big assumption without solid evidence, but it is a possibility.

EDIT: I thought it through, and realized that this theory IS backed up by a fact: Pretty much all members of the BO have no idea such a side-effect even exists. This means that between APTX4869 being forced down Shinichi's throat and APTX4869 being taken by Shiho, nobody else shrank after being given the poison (assuming that the poison has been given to other people)

EDIT 2: My bad, I thought it specified the blood type Conan had, but it did not. All that was said was that it's a rare blood type.

What do you think?

I think this is quite logical. Quite apart from what Conan's blood type actually is, it makes sense for the effects to differ according to blood type or some other properties in the blood, or immune system. There is also the comment made by Haibara (when Conan asked why Haneda Kohji's name came after his in the list of people who were given aptx) that maybe the list was not chronological but rather by blood type or something. That suggests that someone in the BO has an inkling that the victims' blood type is significant.

Is there a possibility that :
- RUM was only meant to kill Kohji, using APTX which was why Kohji's name was in the list
- During the time they were having tea perhaps RUM sneaked the drug in, but accidentally killed Amanda instead. She was never meant to be drugged using APTX and perhaps her name is deleted from the list because it would be bad to admit that the boss' second in command made a mistake.
Not to mention RUM must have confirmed that she was dead while on the scene, so maybe they felt it was okay to omit her.
