There's also a couple things I want to bring to our attention. After reading updates and listening to interviews, especially the one with bio mom and NG, it was mentioned that the witness in the hot tub that was an older guy said he saw someone who looks like Karlie holding a piece of paper. 6:30 or 6:45am it's still dark. Unless this older gentleman has amazing eyesight whose to say it wasn't someone else walking with a piece of paper? <modsnip - not victim friendly>
If you have been to this area, you know that's it's not THAT easy to get lost. The community backs up to the White Mountains but the mountains are very unique and are easy to navigate with the help of the adjacent Sierra Mountains especially Mt. Tom.
Even though they can be easy to navigate, there are a ton of old abandoned mines up in the White Mountains. Has search and rescue attempted to look in them with a drone of some sort? If she was scared and paranoid, what if she tried to hunker down in a mine and got injured or fell into a mine shaft? I only mention this since the dad stated he found her footprints up in the mountains, right? Food for thought here.
