A white, former police officer who fatally shot an unarmed, naked black man is scheduled to make a court appearance on Friday.
Former DeKalb police officer Robert Olsen was indicted earlier this year on a number of charges, including felony murder, aggravated assault and making false statements.
Authorities said he shot and killed 27-year-old Anthony Hill in March 2015.
He pleaded not guilty in June and in DeKalb County Superior Court on Friday, his attorney will ask a judge to overturn the indictment and dismiss the charges.
Olsen's attorney, Don Samuel, filed a motion saying there were at least a dozen people, including a witness and a court reporter, who did not belong in the courtroom when the grand jury heard the case.
Samuel wrote that this compromised the guarantee of secrecy for the jury.
But the district attorney's office responded to the motion and said the people in question were associated with the prosecution and had a legal right to be there.
If the judge rules in Olsen's favor, the indictment could be overturned.
Last March, Olsen responded to a call regarding a naked man acting erratically near an apartment complex.
Hill was an Air Force veteran who, according to his family, suffered from a mental health illness.
Olsen resigned from the DeKalb County Police Department in January.
Disclosure: Defense attorney Don Samuel is related to WABE reporter Molly Samuel.
