Looks like him. Fits some traits, compulsive, needs to talk about, condescending, seems to have inside info, I mean I wrote a profile about this, and looked at pics, but he's pointing out tire tracks and points of entry. The first Reddit killer. And he's not even trying to point away, he's pointing towards himself, he can't help it.
Killers in other generations would attend memorials, call in tips, involve themselves somehow, all he has to is post on Reddit. I wonder if this moves anything at Reddit about content.
