It's a little too convenient that they've tagged both shootings to this on e guy. He might have had a beef with the MIT prof, but why did he shoot the kids at Brown?
And of course, considering the scientist that was killed was one of the leading minds in the nuclear fusion area, it's not hard to see there's a lot more to it
@Reggie_Essent -- possibly the fusion guy was targeted, and once the guy committed that murder, he knew he was cooked, so got in some personal revenge on Brown before he offed himself.
