I really, really would like to know who found the bikes at 2:00 p.m., and what else they may have seen! Were the bikes still on the trail, or had they been moved off the trail? Were was Elizabeth's purse?
My thought is that someone noticed the bikes at 2:00 but didn't think anything of it, until they heard about the girls later in the day. That would explain how the bikes could be found at 2:00 and then "found" again by a searcher at approx. 4:00 that afternoon. The witness probably didn't report it to LE until later that day, after hearing about Lyric and Elizabeth on the news. JMO.
