I can't accept this theory because the girls were supposedly headed toward the lake weren't they? How would this person know to discard them there? Just by coincidence?
No they were not necessarily headed to the lake. Only the lawn watering guy supposed saw them go by, and that timeframe is shaky. They were headed west on Brovan and there are no credable sitings after that. Zero. Somebody would have seen them at some point going that distance. My gut is that they never made it there. Too far ,too fast, without being noticed???
