I know a lot of people have a theory of how the abductor would use the paddle boat to lure the girls. I have a hard time with it though. If it was of such great interest at the beginning of the case, wouldn't LE have checked for fingerprints or other evidence on the boat itself. My problem is, if the boat came back clean for unknown prints (those other than the owners), we have to assume the abductor wiped it down thoroughly after kidnapping the girls. Who would have time to do this other than the owners? (Not implying they did it at all). The person who used it had to take it, paddle it across the lake (alone?), get two girls into it, paddle someplace and bring it back without the owners seeing ... how would he/she know when they would be returning? Also, being in the middle of a lake with two girls in a boat is leaving you in plain sight for as long as it takes you to get to your destination. I would think someone committing a crime wouldn't want to be out and about for very long. In college, I was in a rowboat with a few friends, two of whom decided to smoke an illegal substance. I remember seeing a police car on one of the nearby streets and I yelled at them, "If they see you, idiots, we're in trouble! It's not like we can row away and hide!"
