Police said they found a checklist at Marx’s home in Cumming, Georgia, that matched the items inside the rented silver Nissan SUV used in Friday’s mid-morning attack. Marx had a number of bags and buckets holding homemade and commercial explosive devices that could be clipped to hostages; a gas mask; two handguns; zip ties and two bulletproof vests, police said. They said Marx, 48, wore one of the vests and clipped a hand grenade and wire to himself as a booby trap.

“All the items were checked off,” Forsyth County Sheriff’s Office Deputy Doug Rainwater said. “So this was a very deliberate planned assault on the Forsyth County courthouse.”
