This is my first post, but I've been visiting since the Lisa Irwin case.
I've been thinking about the whole paddle boater as abductor scenario. We've got statements that indicate that the girls possibly went to the edge of the water (since it's not really been confirmed as fact). If they were taken by a paddle boater, or led to a nearby home after crossing the water, shouldn't there be a scent trail at the exit point at some other spot on the lake? From what the SAR experts have stated, even if the perp carried the girls, they would still likely leave a scent trail. Do we have any idea if they actually took the dogs around the entire perimeter of the lake? Unless there was a back and forth trail (a path to and from the lake) in the same vicinity, the lack of searching for an exit trail would make me think that either a) someone dropped the ball or b) there wasn't a true hit on a trail there. Just my inexperienced opinion.
Interesting...can a paddle boat pull right up to the shore, or does it have to pull up to a dock?
