You can find this on the 7/3 cell ping thread.
The male was Sean D. He took Casey by G&C's right after Casey got her tattoo on 7/3. Brian B. is confused about the date, IMHO.
In fact, this is the visit that Casey called Cindy and told her to meet she & Caylee @ Universal so that Cindy would be outta the house. After Cindy returned she was so upset she penned her MySpace, "Caylee is missing..." epistle...and sent Lee chasing Casey down @ the clubs that night, IIRC. I believe Cindy may have been on vacation that week. Was speculated on the tattoo thread Casey may have wanted to get some different bras (e.g. x-back) that wouldn't irritate the new tattoo on her shoulder...just spec though. Interestingly, I don't believe Sean D. is on the witness list...so, whatever he had to say about this trip doesn't seem to be too relevant by inference.
The cell pings track all of the above, and coincide w/ (a) Troy's statement 'bout tattoo guy w/ common name picking up Casey before her tattoo, (b) a pic of Sean D.'s small dark-colored pickup from an onld myspace pic another WS found.
Hope this helps.
