What I would advise if holding off a while until you have some memory of him that sticks in your mind more than others, then try to adapt that to a design you like. You can get initials with it or whatever but if you pick a good image it'll say a hell of a lot more than a name.
Getting it inked somewhere that can be concealed isn't a bad idea but it's up to you. At the very least you may have to conceal it if an employer asks you (if you're thinking about on-your-arm-somewhere), or at the most you may have to hide your identifying marks from the cops
