I followed one because I saw the ghost get into a cab that I wanted to talk to, so the cab finally stopped in the middle of no where, ghost got out, which wasn't the one I wanted, and walked to the beach and poof, was gone. Others that I have seen, get out of the cab, go to a nearby house and just dissappear.
You're right about the ghost's name and I didn't realize until you said something that it was a youth. Very interesting.
