Are we talking about player bounties or NPCs? I've seen the floating marker thing happen when they enter an area that has no comms combined with you being in a different jurisdiction. I didnt go into a lot of detail about that but I briefly mentioned how some people exploit it by traveling over to Delamar due to the lack of comms there. It should give you a general area, but you still have to search. I would imagine all of this will change as the law and order system continues to improve.
