I don't know if it was a slip. He was being asked about Dylan's phone. Of course they would be checking his father's too, at least one would hope.
Exactly, IDK know if it was slip either, but it does make me wonder if their targeted area on a certain part of the lake, may not just be because of the cadaver dog. They did state the big search was not because of a tip. IF MR lost it & Dylan's cell phone was smashed & went off the radar, did Mr's get shut off too soon after? Personally, I doubt it.
