Graveyard Shift

"Hindsight is twenty-twenty," Kazemian says. "There were people who'd say things like, 'He always sat in one chair, like it was his own little domain.' I don't claim to be a trained professional psychologist--I'm a professional engineer and manager--but I never saw a problem. He was the hardest worker I had here."

Tempers have cooled since the homicide, but the violence that shook the agency has left its mark. Today there are not one, but two security guards on the graveyard shift at Wastewater Management. Both of them are armed.
