The reduction means Darius L. Morgan, 19, will be eligible for parole during his 10-year sentence. Morgan, who pleaded guilty in Richmond County Superior Court, will serve 10 years on probation after his release.
Morgan and 15-year-old Naquan D. Cox were indicted on armed robbery charges in the May 24 attack on a young man.
The charge is still pending against Cox. Parole isn’t possible on armed robbery convictions, which carry a mandatory minimum prison sentence of 10 years.
