The director of the Georgia Bureau of Investigation is stepping down after less than a year on the job.

GBI Director Mike Register said he’s accepted an offer to serve as public safety director for Cobb County in metro Atlanta. County commissioners scheduled a Tuesday vote to formally hire him.

Georgia Governor Brian Kemp appointed Register, a former police chief, to lead the GBI and its nearly 1,000 employees last August. The agency helps local law enforcement agencies investigate murders and other serious crimes. Its agents investigate almost all shootings by police officers. The GBI also performs autopsies and runs the state’s crime lab.

“It has been an honor to be the director of the GBI and serve under one of Georgia’s greatest governors, Brian Kemp,” Register said in a news release. “I leave a great law enforcement agency with some of the most dedicated and competent professionals I have ever worked with. I look forward to leading the tremendous men and women who make up public safety in Cobb County and once again serve a great community.”
