Has anyone thought about Shinichi's parents? What if THEY are the heads of the BO? Since the BO wanted to supposedly find Shinichi to kill him, but got orders to find him and bring him in ALIVE and UNHARMED then they would go around just looking for him. They would not be told Shinichi is a kid (Conan) now or Shinichi would wonder who told them, since they dont know what he looks like now. He would deduce there are only a few people that now know of his secret, and they would have to have told the BO where he is, etc. to get him. Only his parents fit that profile. Since his parents are oversesa a lot, they could be the heads of the BO in America. The BO henchmen are looking for Shinichi, but since they did not know he was the son of the Boss, they figured they should use the drug on him to kill him at the beginning. Now it got complicated, the heads of the BO (Parents) find that Shinichi was shrunk to child size, and realise that their orginisation in Japan did it. They need Vodka and Gin to find Shinichi (because they think he is alive and well, thank to the prof.)
