Simple facts guys..we first learn of Randy via Michael saying his name in a dream/nightmare he will not talk about...then , when Tanya is taken...the zom dragging her away is described first as having "long hair, and a beard"...immediately following that Michael identifies him as Randy. Now in this case I would see it less as an oddity among the undead and more as an oddity for people in general..at least in current (2009) L.A. A man with long hair and a beard will stand out far more prominently than a regular dude...this comes from a guy with a shaved head and big beard...so I may know something about uh...follicle profiling
