don't disagree with any of the above posts...
the "story" is consistent with a child going to a game with her family...sits in the stands, sees friends, runs around behind the bleachers, checks in with mom, goes to the concession stand, checks in with mom, goes to the bathroom, runs around the sidelines, et cetera...when she doesn't check in (or is sighted by a parent) for a period of time (1 minute, 5 minutes, 10 minutes), parents ask for a 'missing child check' by the announcer to find her.
not putting words in freesafety's mouth, but the timeline from there doesn't sit well with me either. not on the perp's part, he/she/they panic when they hear the loudspeaker and "finish" or "abandon" the crime in progress. within 25 minutes, on a large campus with tons of parking lots, buildings, and woods/brush to comb through, one or more persons "happen" upon a body. the flood lights from the field would NOT reach that area. no one in their right mind would go in the dark of night to that remote a property considering all the other places she could be 'hiding' (inside the school, a car, an outbuilding, a port-a-potty). it's a miracle one or a group out of a 100 or so people would find her that quickly.
i say 100 because even if there were 500 there, that includes infants, toddlers, elderly, and out-of-towners who wouldn't run 200 feet much less 200 yards in any direction they weren't familiar with.
so maybe it's just that, a miracle...or not. freesafety has a good point.
