do you have a source for the footprints?
On a video, which I cannot locate, a person being interviewed described a searcher finding a set of footprints that he/she followed which led to the discovery of the girls' bodies. During the interview, the person also stated that the searcher could tell right away that there was foul play.
And only this in print:
<snip> Sources tell Call 6 Investigates that a set of footprints are what led volunteers to the area the bodies were found.
