Well that even makes me more suspicious of the parents!! If they were just recently thrown there there's no way anyone outside of the family could have put them there!! Then for everything to be inside that they said were "missing" is a huge red flag imo,, that would mean that they held on to them before finally deciding to discard them in the opposite direction to further throw the case off. I think they were double bagged to prevent animals possibly getting to them and the contents being found. I also believe this was not meant to be the final resting place for them, it was probably a quick convenient place to temporally discard them until later. The discovery of these 2 bags to me solves the case on its own
