There are much better quality video images available. They were shared in the beginning of this thread.
If that is the case, why do many people think he was carrying a "folder" then?
The video still that I posted was enhanced strictly to show Steven was carrying a backpack, NOT a folder. It was enhanced to show the details of the Back Pack Steven was carrying by adjusting the brightness and contrast of the video still that I have posted.
Its my IMO that whatever Steven was carrying in that backpack is the reason why Steven is not here today. Steven was expecting to go back to Utah because he offered to cover for his friend at church, and bought presents along the way of his mysterious travels.
And whatever was in that backpack Steven was carrying IMO was meant to be delivered to someone.. IMO Steven was not having a sleepover, going camping, or going to a "show n' tell" with whatever the contents of this backpack he was carrying.
Steven was picking up something and delivering something among his mysterious travels.. and somebody was paying him for the gas... and agreed price of these trips, IMO.
