I don't recall who pointed out the "C" thing to me before, but, yes...that could've very well been what happened.
Too bad Casey didn't fill out the form herself, eh?
If 4/17 is correct, then, we have something we can work with...
I'm prolly sounding like a broken record at this point, but, we know the same, real ZG that visited Sawgrass had a boyfriend that got a tat recently per video on his MySpace site...and that same bf, Jonathan, listed CIT as one of his friends on MySpace. We know Casey frequents CIT and is very close friends w/ at least one, Sean, if not a couple or so of the employees. Sean & his roomates (brother John, and Lake Vaj owner, Iassen) also all hang @ CIT. All are friends w/ Dante who is a Sawgrass resident. CIT seems to me to be the most likely nexus of ZG & Casey. I'm thinkin' ZG came into CIT w/ Jonathan...and...Casey may have been there. ZG and/or Jonathan mention looking for apt's while gettin' inked...someone says...Dante likes Sawgrass...and they should check it out...and *shazam* the whole thing is born.
All of this would mean Casey needed/wanted an alias back around April 17. I don't think Casey's long-term prowess is well enough established that she woulda recalled all of this in June.
IIRC, JWG posted somethin' bout the April date and the computer search context at the time.
