I think the backpack (the where and the why it was placed there) is very vital piece to the puzzle. :twocents:
I seriously cannot wrap my mind around it. Maybe some angles to look at would be the who:
1) if placed there by the perp how and why was it placed there?
2) if placed there by someone else how and why?
It may have been placed there as a diversionary tactic.
It was found 6 miles from where Jessica went missing, correct?
Maybe wanting to throw LE off that the perp or Jessica is in that area when she nor the perp is in that area.
IMO
Guess, the backpack may have been placed in the subdivision as a calculated attempt to buy additional time. While investigators were expanding their search area. The predator may have continued on up the road to Wyoming, to prey on his next unsuspecting innocent victim..
Only time will tell...
