ATLANTA -- The Supreme Court of Georgia has unanimously upheld Derrick Yancey's murder conviction.
Yancey, a former DeKalb County deputy sheriff, was found guilty in November 2010 of killing his wife Lynda and a day laborer. He received two consecutive life sentences.
Yancey appealed the conviction, saying several critical errors were made during his trial. That appeal was overturned Monday.
According to information presented in court, Yancey shot his wife and 19-year-old Marcial Puluc, a native of Guatamala he hired to do work at his home, in June 2008. He staged the crime scene to make it look like Puluc tried to rob Lynda Yancey, and claimed that he was forced to shoot Puluc in self-defense after Puluc killed Lynda.
