There were a bunch of arrests, most of whom were immediately released. I remember one guy was arrested 6 times in one day for starting fires. I also recall seeing the pics of the fires reaching to the Canadian border, and none on the Canadian side. The chief government agent of the state fire control apparatus resigned after taking a hard line on the arsonists, and stated he had personally overstepped his authority by searching one of his employees home for bodies, so they would't have to do it themselves.
I was on a different computer then, which isn't spun up, or I'd share a few pics and memes to satisfy your curiosity.
