On Monday Doug Williams, a Mississippi factory worker, killed five coworkers before taking his own life in a shooting rampage. Coworkers said that Williams was angry about being passed over for promotions and felt that black people were given unfair advantages. Williams was said to have made offensive comments and threats against other black employees. Over the years, employees had expressed their concerns about Williams to management, and Williams did undergo anger management training for some time.
