Initially upon her disappearance, LE set focus on Peter (guy at the other hotel in MB) and his friends, and then of course the other set of friends that Britanee actually went to MB with who ended up isolating her from the rest of their group for whatever reason. They were really interested in Peter and his friends, not only because he was one of the last people to see Brittanee before she vanished, but because they suddenly checked out of their room in the middle of the night, and booked it back to Rochester to lawyer up. Brittanee's mother has said that his story has changed multiple times as to why they felt the need to leave right at that second, and she thinks that obviously if he was being truthful about the situation, the story shouldn't change. LE doesn't see it that way. LE hasn't said much about any of these kids, other than they believe they aren't involved. They said that they have all been completely cooperative with the investigation conducted. They don't elaborate on that statement, though. They've never said anything about checking any of their phone records or questioning their behavior prior to and following Brittanee's disappearance. The only information we've been given is LE saying they're not involved.
Brittanee's mother has heard over and over from LE that they don't believe any of the friends know or have any information regarding her disappearance. Yet, she is still so set on the fact that they "know something more". A lot of people say she's in denial, but I'm not so sure that's the case. Dawn continues to say "they know more", but she can never elaborate or mention anymore information because the investigation is on-going. It's strange and so aggravating because I think that there's more to the story here, too, but we may never find out what it is, IF it is anything at all.
For anyone who isn't familiar with Brittanee's case, the logical theory/explanation would be that most likely a sex offender snatched her without anyone seeing- it happens all the time now-a-days. Alright, so here we have a sex offender (Moody) who clearly fits the profile and is a habitual offender. Not to mention there's the speeding ticket to prove he was in the same area less than 24 hours after she vanished! They search what was once his residence at the time of her disappearance and then say that not only is he the POI in Brittanee's case, but also in another missing woman's case from a few years earlier (Crystal Soles). Dawn is highly aware of all of this information, but when she's asked about Moody or asked in general what she believes happened to Brittanee or where she is, Dawn always goes back to this group of kids.
Personally, from the information we've gathered and been given, I think the RSO stranger abduction theory is most plausible in this situation.. but I'm not 100% convinced that these kids don't know more. They may not be directly responsible for whatever has happened, but judging from Dawn's behavior, it makes me think they're withholding information to cover their own butts for whatever reason is left.
