As Art Harris explains, coworkers had heard Williams make deadly threats before.</s>ART HARRIS, CNN CORRESPONDENT (voice-over): It was described as a war zone. Mass murder in Mississippi. Armed with a pump shotgun and a semi-automatic rifle, Doug Williams, age 48, started picking off fellow workers. By the time it was over, five were dead, the killer had committed suicide, eight others were wounded and a town in shock was asking why. Some employees tell police they were afraid of the gunman, a 20 year employee at the plant.</s>SHERIFF BILLY SOLLIE, LAUDERDALE COUNTY, MISSISSIPPI: Speaking on a limited number of employees that I've read their statements, there were some employees that possibly felt uneasy.</s>HARRIS: And police tell CNN some employees suggest Williams had made violent comments before and disliked blacks. Williams was white. One murder victim's husband...</s>BOBBY MCCALL, HUSBAND OF VICTIM: She said he made a threat against black people.</s>HARRIS: But the sheriff says the shootings appeared random and the race of the victims doesn't add up to the racial motive. Police talked to the gunman's family.</s>SOLLIE: And we have had investigators speak. They did indicate that he was an angry man.</s>HARRIS: The root of his anger will be part of the investigation, says the sheriff, along with employee interviews and Williams' personnel file.</s>HARRIS: But even if police do find race the motive, officials say that won't undermine community harmony.
