Or, they were planting evidence, like a flip flop, closer to the pond so that Krista could be recovered. If this was an accident and a cover-up by her friends, they would have been relieved that the baby was found quickly but might have been freaking out that LE hadn't recovered Krista after a few days (and Nancy Grace was all over it; the devastated family giving interviews...). Upthread it was reported that the friend of the brother said they were at the scene on Tuesday night because police hadn't searched well enough and they were searching for Krista (and a fort). How did he know the police hadn't searched well enough unless he knew Krista was not abducted from the area where the car and the baby were found?
I think the two men were there when something went down, or they were told all about it...What their involvement is, IDK, but they could have been at the scene to aid in the discovery of Krista, or in attempt to hinder the investigation by tampering with evidence (or innocently searching for a friend, as they claimed, I guess)... I will be following this case; interested to find out how interviews with possible POIs play out and very interested in what the toxicology report reveals. RIP Krista...
