I’m curious - where have you seen posts from her “boyfriend” about her being missing? I’m putting boyfriend in quotes because I think you are referring to the father of Monica’s children, but I don’t think he was currently her boyfriend.
Unfortunately, I’m not able to answer any of your other questions. Though, when I look back at the Kelsey Berreth case as an example, and how her “Missing” pages (those run by family and non-family) turned into a circus of drama and rumors- some fact based, and some not... I wonder if the family has been urged not to start a “Missing” page based on what they (the family and LE) already know, that we are not aware of.
In other words, maybe getting the word out to the general public, would hinder rather than help their investigation. I think they ONLY need to hear from those who know Monica and could give specific information regarding WHEN or WHERE they last physically saw her or talked to her. I have my own ideas causing this line of thinking, but they are only based on my own personal hunches.
This is definitely an unusual case, but things may become more clear as LE gathers crucial information. But it may be a long time before we, as the public, are privy to that information.
