It is especially sad that despite his being highly educated he did not recognize his mental condition and did not turn to a specialist .
In our town there was a similar case .The mad student was running with a knife in the town after killing some next door guys . He had recognized before that he was not OK and asked help from a psychiatrist from a state clinics where the specialist could not care less ...his complaint was that he was attracted to weapons and to the idea of killing too much ... and he was let go home with some pills
If high standard psychiatric treatment were widely available then there might have been less untreated psychos walking among us .
