He found out afterwards that she got fired from work and was pretending to leave for work every day. He worked third and he and the kids were sleeping, he heard something and woke up, went outside. She had come into the house and gotten a 358 revolver and some hot 110 grain "woodchuck loads" and went out into the driveway and she herself in the head. The kids came outside with the guy and they all found her dead body.
Her former employer refused to provide any information as to why she had been fired.
