Derrick Yancey was charged with murder after police accused him of shooting 44-year-old Linda Yancey and 20-year-old Marcial Cax Puluc in the summer of 2008.
Puluc was an immigrant hired to work at Yancey's Stone Mountain home. Yancey earlier told investigators that Puluc had killed his wife and that he killed Puluc in self-defense. WAGA-TV reports that Yancey's son is expected to testify against his father.
Yancey resigned from the sheriff's department shortly before he was indicted on murder charges. Authorities said he cut off an ankle monitor, fled the country and was apprehended in Belize.
