I tend to agree. Hopefully he is not the active shooter being reported at Wright Patterson AFB right now in Ohio.
Selling the guns, to me, screams "trying to make cash to help fund my life on the lam..." vs selling weapons before committing suicide. They say he texted someone to say he was going to commit suicide. I don't doubt he might do it if cornered by the police, but I have to think with 20 years of grudge he had ample time to set aside cash, resources, a new identity, etc, in Mexico or Central America or some other place he'd like to live. It is slightly odd to me that he hung around for a few days before disappearing, but it could've been he was just seeing if he could get away with it. Maybe something happened to tip him off, or when the video was released he realized he was more identifiable and decided it was time to activate "Plan B" and leave.
It seems to me that nursing the 20 year grudge, he was either waiting until he was at a point in his life where he would accept a final exit (ie. suicide) vs being captured and going to jail, so he waited until his father died and perhaps his own health took a turn, or it was just a long simmering planning that he waited until he had trained and trained and planned for a variety of contingencies. He reminds me in some ways of someone I know who is very intelligent, yet also somewhat obsessive and has some difficulties interacting with other people and forming attachments in society. No spouse, no kids, extremely meticulous (the yard, the house, all the planning) described as being chivalrous and kind / helpful, almost to a fault, yet also capable of bouts of rage and anger, and has difficulty getting over perceived slights or injustices no matter how minor, such that something like this could fester for decades. I don't know the name for this particular psychology but I've sort of seen this pattern before.
I have to think the text is almost a distractor to police while he bikes off into the sunset to catch a plane to Mexico or otherwise flee to his new life. I'd be curious if he ever traveled much or had a favorite place to vacation. I could also see him relocating to the mountains or somewhere in the middle of nowhere Arizona / Utah where he could do firearms training under an assumed identity and keep to himself.
