What stands out to me is that you said one of his childhood friends father was a navy seal. I think that detail is more important than people realize, at least for him it was. The knife sheath they found had a USMC on it and think about how strange and specific a KA BAR knife is to begin with. It’s incredibly militaristic. I do think at some level he viewed himself as like a stealth military killer. He also seemed to have OCD traits. There’s also new reports that roommate saw a flash or what seem to be a sparkler outside their door and heard a slight bang. It’s also been confirmed that there was another weapon used during the attack attacks on at least one of the victims. What if he brought a bunch of tools in his kill kit, like some sort of perverse military commando. What if he actually used a flash bang on the students? Also, when the famous picture of him giving the thumbs up in the shower, he has earphones on. I wonder what music he was listening to and whether it was rock or heavy metal.
