Attorneys clashed before a trial jury Tuesday over whether a former prosecutor abused her power to try to protect the men who chased and killed Ahmaud Arbery in the streets of a quiet Georgia neighborhood nearly five years ago.

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.

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.

Officials have summoned more than 200 potential jurors to a Georgia courthouse where a former prosecutor will stand trial on charges she meddled with police investigating the 2020 killing of Ahmaud Arbery.

Jackie Johnson has been charged with violating her oath of office, a felony, and a misdemeanor count of hindering police as they investigated Arbery’s killing.
