So, guy gets fired in the morning, goes home, sulks, and instead of taking responsibility, he decides to go back to work with his gun, and is stopped by the police on the way (Who know nothing about him getting fired) and he goes ballistic. I have been at work several years ago when a disgruntled worker came in with a gun, shot 4 people, and then killed himself. The four people lived.
He just got the source for his drug money cut off....then got stopped by police.....he was on a downward spiral to begin with....
People with drug issues often loose their jobs.
