……

After listening to Taiyi's question, Miwako Sato also felt extremely puzzled, after all, in the process of the trip, he was staring at the whole time, and it was impossible for a knife to hide in his arms.

"Yes~~ He's not a trickster, a suspect who is being escorted by the police, to hide a knife without attracting the attention of the police, it's too impossible."

"This man is not a trickster." Conan's child said that he had already seen through all this, but in order not to let everyone treat it as a guinea pig, he pretended to be ignorant and said.

"This uncle is a samurai! Did you see the knife that fell to the ground? ”

"The knives have fallen like this, which means that the knife was originally facing upwards, so he should be like a samurai, holding the knife in his hand, sticking it in his stomach and then pulling it out."

"Officer Takagi?!! How did the suspect hold the knife when he stabbed himself in the abdomen again? ”

It wasn't clear what was going on. After Miwako Sato, after mentioning this point, Officer Takagi finally thought that there was something wrong with this.

"This person, I remember very clearly, at that time he held the knife with his backhand, so it was easier to commit suicide."

"Hehe~~~" Taiyi thinks that in this way, this case is much more interesting. "This drug dealer used a backhand knife when he committed suicide, but when he pulled out the knife, he did do it smoothly, which is a bit too strange."

Just these people in this, everyone is not stupid, after Conan mentioned this, it is also clear that there must be an inside story in this.

"Is it difficult~~~" Miwako Sato stroked her chin and fell into a state of thinking. "It's someone else who pulled this knife out."

"How is this possible?!!!"

I have been hit by this matter, and I think back to my arrival in Tokyo, how to explain to Officer Takagi, who is already completely masterless, and subconsciously began to refute in his mouth, but before he could finish speaking, Conan grabbed his hand and said.

"If there's anything wrong with it, there's something wrong with this blood."

"Look at this uncle, all the blood that is sprayed around, and all the blood on the knife is like a clotted jelly, one after another. But the blood stuck to his hands hasn't clotted yet. ”

"It's like ordinary water, it's ticking."

Officer Takagi was completely stunned at this time, and he looked at the blood in his hand, which was still flowing, and said in disbelief.

"It's hard to be, these are not blood on his hands, but this color, no matter how you look at it, it looks like blood."

"This is heparin~~~" Miwako Sato knew what it was, "There may be heparin in this blood." ”

"You mean the anticoagulant ?!!?"

After Miwako Sato's remarks, Officer Takagi also thought about what she was talking about.

"Yes, what about the blood after a period of time? Generally speaking, it will coagulate and be transported, which will naturally cause inconvenience, but if heparin is mixed and placed in a sealed bag, the original appearance of the plasma can be easily maintained. ”

"Keeping the plasma in its original ?!!" At this moment, Officer Takagi finally realized what mistake he had just made.

"That's right, if someone hid the blood plasma and this knife in this toilet of this train, then this is a homicide case!"

"The murderer should have caused a commotion with a bomb in the back of the car before committing the murder." Just by contacting the front and back, Miwako Sato can easily come up with the whole story of this matter.

"After I rushed to the scene again, it was when Officer Takagi didn't notice. The suspect was instructed to go to the toilet in the front of the car. ”

"The next thing is to use the knife and plasma hidden in the toilet to create the illusion that the suspect committed suicide. In this case, Officer Takagi would loosen the handcuffs and run over to me himself. ”

"At this time, the murderer, after seeing that Officer Takagi had indeed left the suspect, immediately went to this bathroom, and then officially killed the suspect."

“……………”

After listening to this, after Miwako Sato said this, Taiyi nodded suddenly with realization, and finally understood what kind of method this murderer used, but then again, this seems to be related, and the whole thing is not too much to do!

However, Officer Takagi, who was standing on the side, seemed to understand something, but his face still looked very puzzled and raised a question.

"The wound of the knife I looked at was very deep, especially since I came to check it first after I entered this toilet, and I found no traces of the knife or plasma."

"As far as I can judge, that knife is probably a blade, a retractable switchblade." Miwako Sato she saw at a glance that this little trick was a trick.

"As for the knife, where is it hidden? I think this is probably the inside of the movable rack for changing the baby's diaper. ”

Miwako Sato replaced. The white glove, the carefully opened shelf. "I think the killer should have put the instructions, the plasma, and the knife in here, and then put the movable rack back, and then you won't find out."

"I didn't expect there to be instructions? This murderer is even more high-level. ”

After listening to Taiyi's words, Miwako Sato nodded lightly, "I think it's beauty, it should be a trick used to deceive the suspect and make a false move, after he planted the bomb, he used the suicide illusion created by the plasma and the knife to scare you away." ”

"I think the next thing to do is to instruct the drug dealer to cut off the handcuffs and escape from here while everyone is in a commotion because of the bomb."

"Uh~~~" After listening to what Miwako Sato said, Taichi felt that it was quite complicated, but after thinking about it, he looked at Officer Takagi with the eyes of the mentally retarded.

"Then again, didn't you have a phone at the time, why don't you use a mobile phone and call Officer Sato."

"No~~~" After listening to Taiyi's words, Officer Takagi could clearly see that kind of contemptuous eyes, and hurriedly defended himself.

"At that time, it was because the car had just entered the tunnel..............."
