Yes, it could be that he is still around you. Do you know of a good medium in your area? If so, make an appointment with him/her. IMO, it would well be worth the money. If you don't know any good mediums, one way to find one is to google "Psychics (then put in your hometown)". You should find some references that way. A good medium should be able to communicate with your father and find out what is happening. It may well turn out that none of this is even connected to your father but you won't know for sure until you talk to a medium.
