Thomas Narron, Sr., 44, of Rebecca pleaded guilty to making threatening communications.
Prosecutors said Narron made several calls to a Wal-Mart store in Rabun County last year, during which he impersonated a federal officer looking for an store employee. Narron then called the same store and said there was a pipe bomb in the parking lot. The store was evacuated but no bomb was found.
The case was investigated by the federal Bureau of Alcohol, Tobacco, Firearms and Explosives. Narron, who was sentenced today by U.S. District Court Judge William C. O'Kelley, will undergo three years of supervision following his release from prison and must pay a fine of $1,000.
