McDonald tested positive for alcohol with a .087 level, but he was not arrested because he was not found intoxicated while driving.
“The lieutenant took his keys and gun and took him home,” Wheatley said.
Grovetown is west of Augusta, about 135 miles from Atlanta.
McDonald’s Georgia Peace Officer Standards and Training Council profile shows he changed jobs about every two years after being fired from the Columbia County Sheriff’s Office in 2009.
He had been an officer for more than 20 years, having left his first police job in 1989. He worked as an officer for the Wrens Police Department, which is in Jefferson County.
