The Times of Gainesville reports that Stacey Schoeck on Monday pleaded guilty to murder malice with forethought and was sentenced to life without parole.
Authorities have described the case as a murder-for-hire plot.
Authorities say 42-year-old Richard Schoeck of Snellville was killed as he waited for his wife, Stacey, at a park in the small town of Lula to exchange gifts.
Reginald Coleman and Lynitra Ross previously pleaded guilty to their parts in the shooting death of Richard Schoeck. Authorities say Coleman was paid $10,000 to kill Richard Schoeck.
