"In some cases, the person no longer wishes to remain in contact with her/his loved ones. When this happens, police have to respect the missing person’s decision. In most cases, the
searching family is notified that the missing person has been located but no further details are shared without the missing person’s consent."
Nothing about notifying the public. I'm beginning to believe that any mandates regarding missing persons favour the missing's privacy over the public's curiosity. If she had done something that had motivated her family to state "you're not in trouble," it may not be something that she's want exposed publicly. If LE had found something to suggest she'd gone on her accord, though not located her, I don't think they'd announce this to the public without her consent, and definitely not if it's something that may be seen by some as "trouble."
Again, I don't think they've found her, I just think they might suspect it's not foul play and are acting accordingly. Or they're waiting for someone to slip up. Either way, they're not obligated to notify us if they're taking either direction.
