For me, finding out the RV was playing “Downtown” before the explosion cements in my mind that this bomber had no real agenda other than killing himself in the most interesting way possible. I think he was intelligent, depressed, and mentally unstable. He decided to kill himself but made a sort of game of it. All of us were looking for projects and things to do during the pandemic. This is the project his sick mind came up with. The challenge of getting the bomb together, how and where to detonate it. What “fun” putting the plan all together. Coming up with the warning broadcast...hoping it would lessen others getting hurt, but not really caring if it happened. Probably got a chuckle out of including the song “Downtown” in it. I think he was probably dead in the RV when the bomb exploded. Either shot himself in one of those gunshots people heard at the start of this all, or overdosed on some medication. Or at least heavily sedated himself. Gave his property away because he wasn’t going to be needing it.
Just my thoughts.
