Don't shut down the thread now. The hours before a presser often produce leaks.
Just another thought: Maybe LE has too many suspects? I had one case where a couple was killed. Police had a whole row of suspects: people who the couple owed money to for dope, people who were "swinging" with the couple, even a guy who was hiding items from his bankruptcy case on their property. It was years ago, and no one has ever been charged. To the outside world, this couple seemed like regular people with regular occupations.
It doesn't seem that MT would have anything that crazy in her life, but you never know -- there could be a handful of acquaintances who, for one reason or another, have drawn the interest of LE. Maybe they just need a little bit more to get a search warrant, or a little bit more to narrow in on someone.
The fact that they haven't asked the public for help finding a certain type of vehicle, or help finding someone who was wearing certain clothing, or perhaps even help finding a person in a sketch, makes me think the investigators are doing just fine on their own -- or they have zilch.
One thing for sure: If she's alive, she didn't leave voluntarily. She would have at least logged into her social media by now to check things out, and LE would know it.
