If I put myself in Beth's shoes, the first thing I would do is track down the person my daughter was last known to be with....
In reference to post 1361:
I thought somebody had mentioned NH rented a cell phone on the island because hers didn't work there..maybe one of the Holloway party had called the number when BH was at the house Tuesday morning and she heard it ring
It is possible that one of the Holloway party including Beth had called the cell number at the time Beth H showed up at the VD home the next day after her daughter disapeared..If Beth heard a phone ring at the time she was at the VD home it could have made her suspicious..When I misplace my cell phone I call the number and listen for the ring
