I think LE should focus on the two pieces of evidence that they do have - the bikes and the purse.
Pretty sure this is all LE has at the moment, IMO.
What sticks out to me is this; I watch CNN daily, from AM to PM, and was able to see the interview on Anderson Cooper. Both parents LOOKED exhausted, mentally and emotionally just whipped.
However, I believe it was Lyric's mother than said "We taught both girls how to fight off a predator. To scream, to kick, to bite, to scratch.
We taught them that from a very young age."
(I am editing what I remember, the wording above isn't EXACT.)
What LE should be putting out is the same thing they did in Mickeys case:
Has anyone sold/painted a car lately. Or washed it after the girls went missing?
Has anyone left town, or skipped work around the times the girls went missing?
Does anyone in the area have marks consistent to being scratched or hit around the time the girls went missing?
I think this lake is going to be the Achilles Heel in this case, I really do.
The only conclusion I can come up with revolves around where the people we know were around the time the children went missing. Then migrant workers, or movers, or utility men, etc. etc.
I do believe, though, LE should release something related to the "possible" attacker. Scratch marks, IMO, are huge because it plays off of what Lyric's mom brought to the table.
But then again, we have the element of the girls getting into a vehicle, or leaving with someone they KNEW. My gut is screaming this for some reason.
