Could you share your theory using generality rather than specifics, so that we can discuss it? If you think it's family you could say someone close to them, if you think it's a witness say someone in the community, if you think it is someone not yet mentioned you could say unknown perp.
I just find it helpful to discuss theories, it can really be an eye opener.
No worries, as long as I'm not going to get beaten up again for doing so.
Trying to walk a fine line here with TOS but here goes -
First of all you can totally disregard all paddleboats, puppies, fishing boys, horses, campers, Craigs Listers, online boyfriends, empty houses, second hand sightings.
The witnesses we know about are not involved apart from being honest citizens.
I believe the girls arrived home that day, shortly after 12, as expected. I believe they went back out again on a "mission" of some sort.
I believe they COULD have been to the lake earlier on this mission, were not successful, and had to go back a second time, and quickly!
I believe they were captured either right at or very near the lake. By a white van.
I believe TG saw the bikes when he said he did, (maybe about 12.23) and Mr C saw the girls at about 12.18 but has been told to be vague.
I believe they were then intercepted by someone they knew with a story, such as, gramma has taken ill, drop your bikes, quick lets get to the hospital.
I believe the girls may well have been still in the wooded area when Mr G biked past.
I believe there was an older male perp and a younger male perp.
I believe that IF the bikes were staged, it was done by the younger perp under instructions, who then left on foot therefore was not noticed.
IF they were staged, the younger perp went so far as to drag items of their clothing around the scene to confuse the scent, as he had been instructed.
I believe the girls were first taken to Elk Run Heights...perhaps a property, perhaps just a meet up with another perp/vehicle.
From there they were taken God knows where.
I believe the original plan was merely to hide them (motives I cannot discuss) but the main instigator has done a back flip and actually murdered them on the day...he had always planned it this way unbeknownst to his co-conspirators, some of whom had no clue this was part of his plan.
I believe the motive is not sexual but money, and/or another benefit, and I believe this part of the plan has worked out as hoped.
This was VERY well planned, and not random.
All my humble opinion and not intended to replace fact.
I could well do a 360 if other evidence comes to light but based on what we have, that is what I believe happened.
