I just read some interviews with the former high school principal in the suburb of Dayton, where the shooter resided (apparently with his parents). The former principal recalled suspending the shooter for writing a “hit list.” A former classmate also recalled him and the hit list, recalled that he had been “bullied” in high school, and when she first heard of the massacre, she said his name was the first one which occurred to her.
A former friend said the shooter was quiet and seemed normal…except for the hit list incident, which he (obviously) never thought of as anything other than a prank. The former friend said he had spoken with the shooter c. 10 months ago and had a normal conversation with him about everyday things.
One of his victims in the area was his own sister, who seems to have ridden with him to the area! Dayton Police know of nothing about any catalyst for the shooting. No racist rants, nothing. Parents are upper-middle class with a very nice suburban house.
6 Dayton policemen combined to blow him away. He carried 50-bullet magazines for the rifle, all legal here in Ohio…
The mentally ill, in my experience with them (limited, but possibly more than usual I think), are often able to mask all of their symptoms: that would seem to be the case here. Who knows whether he experienced hallucinatory voices, images, etc.?
