The one-time Georgia prosecutor accused of using her office to impede the investigation into Ahmaud Arbery’s killers is set to stand trial more than four years after the Black 26-year-old’s death fueled nationwide protests over racial injustice.

More than 200 potential jurors were summoned Tuesday to a Georgia courthouse for questioning about whether they can serve impartially in the trial of a former prosecutor accused of meddling with police as they investigated the 2020 killing of Ahmaud Arbery.

At the time Ahmaud Arbery was killed, Jackie Johnson had served for a decade as district attorney for the Brunswick Judicial Circuit. Greg McMichael worked in her office as an investigator before retiring in 2019.
