Some here post with an authoritarial tone that has the effect of giving great weight to their words. One might construe from those posts that LE doesn't suspect the parents at all in this case; that LE doesn't have any idea what happened to Isabel Celis; and that LE is, in fact, completely supportive of the parents and their actions.
But the record says otherwise. We remember the times LE has questioned the parents' behavior and called them out for their lack of concern; we remember that the father in this case is not allowed contact with his other children based on info that came to light in the investigation of his daughter's disappearance; we remember LE's comments, both on and off the record, about the Celis' lack of candor under questioning. We recall LE's actual statements that the parents lacked "a sense of urgency" about Isabel's "abduction," and when they released the 911 call, we heard that lack of urgency with our own ears. When looking at the facts in this case (all documented here in these very threads), it becomes clear that LE are focused on the parents as the "perps."
IMO, for LE, this is not a "who done it" case but rather a "we know who done it and we've removed the only children who might be in harm's way from having it happen again." LE is in "sit tight" mode until the parents produce the child because they believe, as do many others, that she is not dead; and that she is being used as a pawn in a money and publicity-making scheme cooked up by her parents.
They're not looking for her because this is not an abduction.
They're acting as responsible stewards of the public's money, knowing they have massive leverage over the parents with the no contact order. In other words, they know the parents will have to produce her at some point if Dad ever wants to see his sons.
That such a massive fraud could be prepetrated on the public for money and fame is sure to outrage the citizens of Tuscon, and these parents face unprecedented charges.
