Okay, I have a theory I'm tossing around now, because of this:
TB "an aunt to both girls, said all the signs were pointing to a stranger — possibility a pedophile — abducting them from the area near the lake where their bikes were found."
Lyric and her cousin, TB's daughter, were so late a few days before the disappearance, the family was so worried about there whereabouts that they called the Waterloo PD. They had reportedly been at the park at one point while they were gone.
TB, according to Gracelin's thoughts, may have interrupted something involving one of her daughters plans on the day the girls went missing.
TB was the one whose lightbulb went on when she said they needed to go to the lake to find the girls, when GMA returned with her from Waterloo the day the girls went missing.
When she says, "from the area near" where the bikes were found...that is really specific. I think that sounds like the (Maiden Lane) woods...where she says the dogs scent led.
It could even mean a house nearby, but she says "area" and she stressed the scent went into the "forest", etc.
So...I'm thinking that TB's gut feeling was based on connecting some dots.
I think those are some of "the signs".
I don't think she knows who that person is, but she may have an idea and if she does, I'm sure LE is following that lead.
MOO
