A Georgia golf pro was killed on the 10th hole of a country club over the weekend ... and witnesses say the scene was absolutely terrifying.
Gene Siller -- the director of golf at Pinetree Country Club in Kennesaw -- was working Saturday when someone drove a white pickup truck onto the course before stalling near one of the hole's greens.
Witnesses tell WXIA when Siller showed up to the hole to investigate ... he was shot and killed by the driver.
