The Georgia Bureau of Investigation confirmed it has completed its investigation into suspected inappropriate spending and use of cars owned by the Douglas County District Attorney’s Office.

The findings of the Douglas investigation, which District Attorney David McDade requested last May, are not known. The Attorney General’s Office, which would prosecute any crimes the GBI discovered, declined to comment because it is an “open investigation.”

Channel 2 Action News is reporting that McDade’s attorney will announce at a news conference this afternoon that McDade is retiring. WSB TV also reported that attorney Drew Findling will announce that the GBI’s findings on McDade will not be presented to a grand jury.

If a grand jury considered whether criminal charges should be brought against McDade, Georgia law says McDade, as a prosecutor, would have the right to appear before the grand jury. McDade has been in poor health since late last year, when he was hospitalized, and it would be difficult, if not impossible, for him to come to a grand jury.
