David Wayne Moore, 30, was one of the workers killed in a calculated workplace attack at the R.E. Phelon lawn-mower parts plant in Aiken, South Carolina, on September 15, 1997. A tool-and-die machinist with close ties to his fiancée, church and extended family, he was shot at his workstation during a barrage of gunfire unleashed by a former employee who had been fired weeks earlier.

The assailant arrived with a semi-automatic pistol and multiple magazines, shot the plant’s security guard and personnel manager, tore out phone lines, and moved through the building firing into work areas. Co-worker Ernest Leonard Filyaw was also killed; several other employees were wounded, including Lucius Corley and John Mitchell. The shooter was found semi-conscious after ingesting insecticide and taken into custody at the scene.

The sequence of events — disabling communications, targeting a former supervisor, then moving through production areas — raises questions about the attacker’s planning and his route through the plant. If anyone worked at the plant or knew David’s routines that day, please share what might still help explain how this unfolded.
