Okay, let's just say, hypothetically, that someone nabbed the girls in town, and decided to put the bikes at the lake to deflect attention away from themselves.
How would they get the bikes to that specific location? They couldn't drive them in very closely. They would need to park in a hidden location and then walk the bikes there.
Does that sound feasible or possible or even likely?
Would 2 people ride them there and then abandon them? They would have to walk away and then get picked up?
It has been speculated that a vehicle could back into the wooded area nearby, but would still have to get the bikes over the 8ft fence. A purse was found on the lake side of the fence, the bikes on the trail side. It has also been speculated that someone else, perhaps local teens, could have come across the bikes and raced down the trail to that secluded area, which would provide them some cover while they checked the contents of the purse. They would then not be seen just abandoning the bikes. However, given the timeline and the sighting of the bikes on the path by a cyclist, that would mean that they would have to have left their bikes, the bikes get found, the bikes get ridden and abandoned, then the cyclist spots them w/o riders, all within 10 minutes.
