Everything seems to point to "______ or Walkway."
The money points to "Suicide or Walkaway."
The clandestine meeting points to "Foul Play or Walkaway."
And as you noted, the bloodhound points to "Foul Play or Walkaway"
Witnesses indicate he may have met one or more individuals in Lewisburg.
At one point, he had an extended wait time.
He disposed of a County owned computer and hard drive in the river after removing the hard drive from the computer.
He was deceptive towards this significant other. This was grossly unfair to his significant other and
may have been one of the causes of his acting unusual...guilt.
He left no record with his office about a meeting with anyone. It the meeting had been one of an official matter, he would have left a note or informed someone were something to occur, so I think we can safely surmise that it was an "off the books" meeting, and to a degree, deceptive as he took a day off for the meeting.
He was acting unusual prior to the Lewisburg trip. Was the time period he appeared to be acting unusual between the first attempt at the lake and the Lewisburg trip?
It appears he attempted to dispose of the computer prior to the Lewisburg trip. This tells me that
what was on the computer was more critical than
where he disposed of it, as long as it was in water and would not be discovered for some time. Searches about hard drive data destruction support this. Not having this task performed by a professional, to me indicates more deception. When the first attempt failed, he picked a more remote spot and adjusted his plan accordingly.
I wonder if he would have made the Lewisburg trip had he been able to dispose of the computer at the first attempt? To me the route taken to Lewisburg indicates wanting to take an enjoyable last drive in the Mini. I know that if I was going to take my last ride on my Harley, I would pick a very nice stretch of road where I could safely open it up, and where I would have some wonderful views of the countryside.
