Decatur, Georgia (CNN) -- A former Georgia sheriff's deputy convicted of murder in the slaying of his wife and a day laborer in 2008 was sentenced Friday to two consecutive life sentences plus five years in prison. 

That means that Derrick Yancey, 51, will have to serve at least 60 years before he is eligible for parole. 

He stared straight forward and showed no emotion as a Superior Court judge imposed the sentence for the murders of Linda Yancey, 44, who was also a sheriff's deputy, and Marcial Cax-Puluc, 23, a day laborer from Guatemala. 

Referring to Linda Yancey, Judge Linda Hunter said, "She was an officer, she was a wife, she was a mother, she was a daughter, she was a sister, she was a friend. Mr. Cax-Puluc, who had barely began to live his life, he died that day. It's not lost on the court, and probably yourself, that today an officer has fallen because you were a law enforcement officer entrusted with so many responsibilities." 

Hunter and the defendant, who both worked at the Dekalb County Courthouse, knew each other, prosecutors have said. 

Yancey was convicted earlier this month of two counts of murder and two counts of possession of a firearm during the commission of a crime. 

Cax-Puluc and Linda Yancey were shot multiple times in the Yanceys' home in Stone Mountain. 

The defendant told police that he shot Cax-Puluc in self-defense after the day laborer had shot his wife. Prosecutors argued that Yancey was the lone gunman and that he hired Cax-Puluc as part of an elaborate plan to kill his wife.
