I found an article indicating they're aware of the possibility and don't think it's him:

That was a great find!
From what that article reports the police as saying, I can't see real obstacles to matching the UID with Scott. I realize Scott left a suicide note, but there doesn't seem to be any evidence he actually killed himself. Perhaps he just wanted to disappear permanently? And had just gone to the woods to hang out for a while until he could make decisions and move on?
To me, several features of Scott's case complement UID's, e.g. UID's car has never been found, but Scott's car has.
It would help our case if the police had said whether:
-Scott had backpacking experience
-Scott was a heavy smoker
-there was a "Lib" in Scott's life
-Scott had damage to his back, or if he was taking painkillers perhaps not knowing what the problem was
-Scott liked to play games, e.g. Battleships
-Scott owned a pair of Sharper Image binoculars
-Scott had a pair of boots with a hole (although this could have happened on the trip, or these could belong to a thief)
-there was non-backpacking clothing in Scott's car, or other detritus that gets left over while packing for a backpack trip
-if that pack was purchased in Grand Junction (there's an REI there, and other outdoor stores); I'll bet several of the other items (e.g. the filter and bear spray) were bought at the same time
-Scott had credit cards with him, and were credit card purchases tracked to see if backpacking equipment had been purchased (that Jansport pack really sticks out to me)
It's interesting how little information LE seems to have on Scott!
