There are many candidates and most of them have self portrayed them to the world they are original creator of bitcoin but didn't have any valid evidence to prove themselves against their fake claims so in my opinion we should not look for some connections and disturb the personal life of people and making them in whole media coverage if they deny the fact and let this mystery as it is because we all are satoshi in the end.
Maybe they are not even there anymore, maybe they passed away, we do not know. Plus, I feel like it doesn't even matter, we shouldn't really look for satoshi because in the end satoshi doesn't even matter, I personally believe that the best thing he ever did was to remove himself from the calculation, that allowed him to continue existing without caring about what could happen to him, and allowed us to not be worried about the owner doing something silly.
Even satoshi "saying" something bad, would cause bitcoin to crash, it has nothing to do with bitcoin itself, but just because he is the creator, that would be bad. Hence, it's best we do not know who they are.
