Thomas Eugene Bradford, 43, is accused of fatally shooting 38-year-old Raymond V. Lee, of Grovetown, at a Martinez wastewater treatment plant.

Authorities say Bradford, a driver for Thomson-based Hudsons Grassing Co. Inc., and Lee argued at the Reed Creek Water Pollution Control Plant in Martinez on April 1. Witnesses said that during the argument and physical fight between the men, Bradford brandished a pistol and shot Lee.

Bradford called 911 and waited at the scene until he was arrested.
