The Tennessee Bureau of Investigation says a fatal shooting at an East Tennessee plant occurred while an employee was meeting with his supervisors. TBI spokeswoman Susan Niland said on Friday that the investigation indicates 45-year-old Ricky Swafford became upset while talking with two supervisors at the Thomas & Betts Corp. plant and left the building before returning a short time later with a gun and fatally shooting 44-year-old James Zotter and 68-year-old Sandra Cooley.
