Since Kim and Crystal didn't know each other, I wonder why Kim cared?--maybe they share the same pimp?--
I thought I'd read they were from two different escort services, but that doesn't mean they don't have the same pimp. Some of those guys operate more than one agncy.
I don't think Kim wanted to be involved with Mangum, but maybe she has enough of a conscience that she didn't want to just leave her there in that kind of condition either.
Something occurred to me - I wonder if Nifong has looked at Mangum's cell phone activity during the time period she was supposedly being raped? If she was trying to call her pimp/BF during the time she was supposedly being raped, Nifong is going to have one of those big, "Whoops!" moments coming to him, lol!
