He studied business and then law at George Washington University and then graduated from Emory University School of Law in Atlanta, Georgia, in 1972. At the time of his death he held the title of adjunct professor at Emory. Barnes had served as a city judge and a magistrate before his appointment by Governor Zell Miller to the Fulton Superior Court in 1998.

Barnes was murdered in his courtroom on March 11, 2005, by Brian Nichols, who was convicted for the crime and sentenced to life imprisonment. Nichols attacked a sheriff's deputy and was able to take her gun, and then went to the courtroom and shot Judge Barnes, his court reporter, and later a sheriff's deputy and a federal agent, all of whom died of their injuries. Nichols was taken into custody at an apartment complex in Duluth, Georgia, the following day.
