As for the murder weapon, it should be a poisonous needle clamped in the cigarette. Pretend to take out the cigarette and press the bottom of the soft cigarette box to let the cigarette stick out without touching the cigarette with your fingers. Then just hold the cigarette box and use the needle clamped in the cigarette.

Stinging the deceased with a poisonous needle will not leave fingerprints on the cigarette. After that, stick the chewed gum on the cigarette, wrap it in paper, and throw it on the ground. When someone walks by and steps on it, you can take the murder weapon with you.

"No," Conan couldn't help but interrupt. If he didn't say a few words to indulge his addiction to reasoning, he might not have the chance later. "He chewed gum in front of the police because he was worried that if this method was seen through, he would become a suspect.

The subject used reverse thinking to make people think that if he was the murderer, he would not be able to expose chewing gum in front of the police. Therefore, I think he probably picked up the chewing gum and cigarettes from the ashtray, even if it was mixed with his saliva.

"So that's it," Judy was not stupid, and she also reacted. "The clerk took out the coins from the game machine before, but now there are not many coins in the game machine. As long as the police investigate, they can find him on the coins he put in for the deceased.

There was no way for him to say that the fingerprints were the coins he put in when he played before, because after the clerk cleaned the coin box, the deceased had been sitting in front of the game machine, and only the deceased could put coins in..."
