The Commercial Dispatch reports that James "Chuck" Newell was convicted Friday in Lowndes County Circuit Court in the slaying of Adrian Boyette.
Circuit Judge Lee Coleman set sentencing for Sept. 7.
Newell faces up to 20 years in prison.
Newell, of Vernon, Ala., had been convicted of manslaughter in 2009, but the Mississippi Supreme Court overturned the verdict and sent the case back for retrial.
Authorities say Boyette was shot to death after an altercation outside the Slab House, a bar on the outer limits of Lowndes County, near the Alabama state line.
Newell claimed self-defense in the slaying.
