To some degree we will never know what set him off but I have seen people who were pushed and pushed and then they admitted to wanting to kill but never did it. Just wanting to kill does not mean "mental illness". It means that the person was "f'ed" with. He may have run out of money and that was the trigger to push him into despair. We also know that governments are not honest and they will not truly tell the truth in dealing with personnel matters regardless of the person's skin color. In some ways I think he is already dead and that he committed suicide but that is just from reviewing similar typed events. I just hope they find his body alive or dead soon.
