I’m sure they are being given vague details, but it’s tough to say for sure if there has been a pivot here towards foul play. It does seem that they are easing the family and public in that direction, and that website did use the word “recovery” (ominous) and used words to the effect of “potential foul play.” Their words at the press conference were more of the same however, and they have characterized Mollie’s disappearance as just that, as they have in the past.
So basically the words said at the press conference, didn’t jibe with the language used on that website. Whether this is relevant or not, I’m not sure. Although I think most of us have assumed foul play from the beginning, and thus, an unhappy ending at some point.
