Some thoughts:
So, its been bugging me, the latest release from the Sheriff stating "After a massive and exhaustive search in a several mile radius around Diana Alveres’s home it has been determined that there is no evidence to suggest that she is in the area." It reminded me of another case, this virtually exact phrasing, I've been trying to remember for the life of me where I heard this before...it hit me in the middle of the night: Malik Drummond. Remember they searched every nook and cranny, despite their hinky meters probably on full alert with the dirtbag dad (who by the way was just sentenced; different type of case, I know...).
Now, why is this possibly significant? Well, I know there has been a massive search by LE and their resources, but this is also swampy land, alligators, and many private homes, etc, so just because they have not found her, does not mean imo that she can't still be in the area. What I'm getting at is this: LE has not stated once that there could be a predator, for people to keep an eye out, walk in groups, etc, and for the community to "remain vigilant", as they often do in abduction cases. My guess here is that they either have leads that they are still following up on, which indicate she is not in the area. Hard to explain, what I'm trying to say is I'm not getting the feeling from LE that they are leaning towards a "random" predator. And if they are, they've got their eyes on him and don't need the public's help.
Also, I realize it takes time for evidence seized from the home to be processed. I'm guessing they didn't find anything to indicate something might have happened in the home yet, as nobody has been arrested? Actually I take this back, they would need time to put their ducks in a row (say hypothetically if they found blood in the home, etc.).
