Mine is kinda boring, but I would ask for timeline clarification, if possible, just so I can get the story straight in my mind...
Yes that is a good question, there is a lot of unclear and conflicting info regarding timeline
One question is whether she might have had a phone with her considering she had multiple phones. What was the date of the last call to her on the phone police took? When was the last call or text on her phone that Payne has?
I don't know much about cellphone triangulation and location tracking, but couldn't the FBI get a timeline of when and WHERE she was at the time of her calls?
I do realize that Crestone is a bit remote, but a new cell tower was just put up in Moffat a couple of years ago. Moffat is only 15 miles away.
Kristal was also involved with a band around that time - have they been questioned?
