i already knew that nishitani was the culprit because conan went to the mens bathroom and said "im sure that 'he'is the culprit" (mouri and conan are exceptions then the only man in that place is nishitani right) 😏

Conan's hint: Ring

Filler

Ok yeah it's pretty obvious who the killer is when Conan starts talking about the thing he found outside the mens bathroom.

I think that it what Kogoro deserves for trying to eat an entire fish whole.

I hope they’ll send the son to jail

They do

well,they send the criminals to jail (incase you dont know, watch the scene after the ending song,its on that part of the anime where they arrests the criminal,or mostly say their opinions and stuff)
