Interesting to see someone whose decision making is so disordered that they manage to carry out a shot from 200 meters and then disappear. That looks more like a carefully planned crime than madness.
I think that's the mixup. You can be insane but still perform some very calculated plots.
The shooter is also in custody already and captured thankfully.
The first person of interest was detained, but released.
FBI director says a suspect is in custody. That governor says a person of interest is in custody. Local police say the shooter is still at large. This is what Reuters was reporting as of 1 hour ago.
