Interesting question,
@Rosegold68 -- MOO -- am thinking that the suspect is either a "people-type" worker (think: EMT, clergy, local community volunteer/volunteer leader, etc.), OR is directly related to someone who is.
Thus, the suspect received "insider" information
very early on (i. e., info. that everyday Delphi residents would
not know, short of knowing/being related to an "insider" who
leaked that information).
Just "me", here, but am wondering,
If I were DC, would I be feeling frustrated -- and betrayed -- to have shared "insider" information with a "people helper"-type person who was part of the Feb. 13 & 14, 2017 searches and community efforts, all to come to realize that the "insider" is someone who is either a friend/spouse/parent(s) of the suspect? And -- that the "insider" has unwittingly passed along that private information?
You bet.
