Thanks for you answers, but in some episode she loses a data of something on PC, what was that data? something related to the drug or something else? , I have more questions xD, http://www.mangareader.net/139-8047-33/detective-conan/chapter-1.html
1.)Kudo saw the guy who gave the BO money, so instead of chasing BO why doesn't he chase that guy? it's easier also safer moreover if he catches that guy he can get to BO through him.
2.)That guy seems like he knows about the BO actions he says "Shut up compared to the stuff you guy do we are..." so does that man have any contact with the BO?
