I said this same thing in my posts, that I hope they have investigated much, much more than has been disclosed thus far, i.e. luminol done in the homes where she'd been staying, the homes where the parties went on, at the club, in the cars of all the roommates and the folks who were coming and going, the cadaver dogs used in all these places and the grounds and dumpsters around them, to include Sutton Place, Glenwood, Lake Vaj, the Oviedo house, Sawgrass, the other complex where TL was looking into moving, etc, and flight manifests of all those flights the friends took here and there, etc. If it were me, also computer records from everyone. I mean, usually if a child is missing , they do investigate all the mother's associates, it seems like that's a given in an investigation. Don't they?
And if they suspect the child is deceased, so much more reason to do all the above.
