Those go go bars (and there's more than one) in the area where she worked is very close to a Naval Shipyard. There are plenty of sailors that live on ship and in the area surrounding it. I would assume that some may frequent the go go bars (otherwise why would they put all in one area?). I think I or someone else had mentioned before that it would be easy for someone in the military to somewhat disappear after her murder/disappearance. I so hope they find out what happened to her.
I mentioned the fact that if they were in the military, they might have received orders taking them out of the area or they might have even gotten out of the military moved back where they were from originally. I know a few others had that thought as well.
