Well it's not like it's not getting news (ABC News) and it's not like no one is looking (FBI is involved).
They spend over half the article talking about the complaints of a double-standard, when if that was me in that case and my daughter/sister was missing I would rather let the police do their job and would prefer to keep it a more private matter rather than wanting Nancy Grace to give her opinion and theories.
Sure there is a double-standard, no doubt, but is this the kind of case where you really want to point that out? The odds of someone watching it on the news and going "oh yeah, I have information on that" is far outweighed by the insuation, true or not, that the victims families just want 15 minutes of fame and a monetary award from a civil suit.
