The Search page was deleted because 1) it became obvious there was someone leaking information on search locations before the searches occurred and other sensitive information outside the group and family, 2) There was (and still is) real concern that the operations were infiltrated by one or more individuals who may have ties to possible abductor(s), and 3) After all the mud slinging and threats of lawsuits after the search on Constitution drive, many searchers and professional assets including myself decided to step away rather than risk being caught up in a legal mess.
In addition to the above, there was an individual who was a great liaison with PSP that was pushed aside by others with personal ambitions and the hard earned rapport with LE was lost due to a few individuals willy-nilly calling PSP with conflicting information to the point where PSP got sick of it.
And since I am an insider on the case from the beginning, I stand by the above.
