Who does online searches to find out how to destroy their hard drive, calls their significant other to tell them they need to feed the dog because they may not be there to do it, then decides to drive far away to look at antiques -- in my opinion, someone who has been planning to get out of dodge for a while, and who has been carefully setting up the "escape." I have a funny feeling this is a man who kept many things hidden inside, and did not want to share those thoughts and feelings with others. He had his "public" side, and his "real" side -- and maybe, the "real side" said, "I'm sick of living like this, I'm getting older, so I may as well go for it now while I'm young enough and healthy enough." Mr. Gricar is a smart, good looking, (probably charming?) man -- I imagine he could make good for himself just about anywhere. So why stay in Bellefonte when there could be other more interesting places for him to be. And as many others before him have done, he may have decided it was better to just roll on down the highway rather than face all the questions and emotions from friends/family/etc. Once he made the decision to split, he may not have felt like handling all the ensuing pleas to stay, etc. Maybe he just wanted out, and rather than worrying about the reactions of those he was going to leave behind, all he felt was relief. Just trying to get inside his mind and follow what he may have been thinking in the years/months leading up to his disappearance.
