ATLANTA - A Georgia death row inmate convicted of murder in the slaying of a store clerk who was scheduled to testify against his son is to be executed next month, the state attorney general's office said Tuesday.

Tommy Lee Waldrip is set to die at 7 p.m. on July 10 at the state prison in Jackson, Attorney General Sam Olens' office said in a news release. A Dawson County jury in October 1994 convicted him and recommended the death penalty for the April 1991 killing of Keith Evans.

His execution date comes on the heels of the June 17 execution of death row inmate Marcus Wellons, which was the first in the United States since a botched April execution in Oklahoma.

Evans was a store clerk in Forsyth County and had testified in the 1990 armed robbery trial of Waldrip's son, John Mark Waldrip. The younger Waldrip was convicted, but he was granted a new trial and released on bond, according to Georgia Supreme Court records from Tommy Lee Waldrip's case.
