I remember asking early in the case but never found out, were any of her pings consistent with any stops by the Lake Vaj house? (On any dates really in June-July, sorry to be so vague)
Also, the "loops by the remains site"-- could she just have been driving by Lee's thinking of going there, looking to see if he was home, or actually spending any time at Lee's, or scoping out her parents' house with thoughts of going in for some of her clothes or other things if she could get in and out without them hassling her, etc? (or for gas for example, from either Lee's or her parents' home). What else is in that ping area? Kio's parents house is there, don't know if Kio was there at the time (I only mention because of Kio's first story to LE about having gotten back in touch with Casey, Casey needing to borrow money, the discussion of let me know where to meet you with the money, etc, of course later recanted by Kio and she gave different dates anyway, July 9 I think, but anyway), what else is within that ping area, the house at the end of the street (the F. Gonzales house, the one that backs to the remains site) was it already for sale then, was it vacant? The Brackenwood house.... just trying to remember what all is within that ping area
If Casey is the killer, I wouldn't doubt if she did loop by the remains site--whoever the killer is, Casey or otherwise, I wouldn't be surprised if they returned to the scene MOO
