Episodes 507-508: The Dead End in the Karaoke Booth★★

I find it totally unreasonable that Conan suspects Eisuke Hondou. He suspected him because the victim was an FBI agent, and Eisuke said he dislikes being restrained, which led to him being suspected of murder. But would an FBI agent be so easily killed by someone who might bump into a utility pole while walking down the street? The victim deserved it too, getting involved in a previous kidnapping case. This time, he was stalking Sonoko. I don't really understand why someone who wants to kidnap people would keep taking secret photos. And since they kidnapped a child before, why did they suddenly shift their focus to a high school girl walking with everyone else? Maybe they knew Sonoko's family was wealthy. The method of murder was quite clever, using coins stuffed in socks as a weapon and even using a vending machine to spend all the money. However, when someone later tried to get a refund or the vendor came to collect the money, they would have found a pile of blood-stained coins and figured out how the murder was committed. It was a gamble; if someone else had been around when the act was committed, they would have been caught immediately. In the end, the culprit tried to make excuses, but Conan, using Sonoko's voice, pointed out that no one mentioned the victim's gender. Yet, the killer knew the victim was male. I was stunned when I saw that. Isn't it obvious from the body that it's a man? (Or did I misunderstand the plot?)
