Among the items found in his house ringed with security cameras are several kinds of acid, as well as hexamethylene triperoxide diamine (HMTD) and pentaerythritol tetranitrate (PETN), homemade grenades, blasting caps, firearms and 50 pounds of hexamine.

Is Hexamine a realistic explosive ingredient? I used it as a fuel source for hiking, but I didn’t realize it could be explosive. Produces a lot of heat for a long time in a small package, though. I made the mistake of testing one full bar with my homemade camp stove setup in my kitchen once, and almost had to pull out a fire extinguisher, the flames were going so high.
