My first thought, early on, about what happened to the daughter was right. Every time they try and lead you to a different suspect you know that they are trying to fool you. Could have done a better job explaining what happened to the other female on the boat at some point. And why is it dozens of cops are around day and night, but never there when the husband and wife are out at night? And how can they escape in that huge RV and the cops not chase them down easily? This had the makings of a solid movie, but they seemed to drop the ball every chance they got.
