Good thinking, nice catch. I don't think anyone would have accessed the recording prior to the discovery of the bodies. Had the parents or anyone gotten a hold of that recording I think the area would have been flooded with LE immediately, that night. Probably a tactical group with thermal imaging goggles and scopes as to not destroy evidence in the dark but they would have been out there immediately. They would have sectioned the whole area off immediately as well, volunteers wouldn't have been conducting the search, I think it would have been all LE had they known what they were dealing with.
I do think the calling off of the search the night before was a tragic mistake. Even if the girls hadn't been met with foul play, it was February in Indiana. I think they would have had a tough time surviving the night out there in the woods with no shelter or way to keep warm even if they were just lost. Which really makes me question the decision to call off the search at dark. It gets dark here in February around 6 pm which means by the time searchers got started they probably only had an hour or so to work. I think dogs could have found them very easily also, regardless of the dark. It might not have changed anything but I know rumors are one of the girls survived most of the night and had only died within hours of being found. How much truth there is to that who knows. It would have given LE a 15 hour jump on BG regardless. And if the girls had really just been lost it would have very likely saved their lives.
Hindsight is 20/20, I just don't understand why they called off the search when they thought the girls were lost out there in the cold.
I suppose they might not have actually thought the girls were lost out there, they might have figured 12-13 year old girls probably had just gone to a friends house, bf's house, something.
Unless/until this thing goes to trial we won't know much of anything that went on. if/when it goes to trial some pretty horrific stuff is probably going to be brought to light also.That recording will likely have to be unveiled during the course of a trial. I don't even want to imagine what that contains. Life changing horror I'm sure.
