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.

DECATUR, Ga. -- A DeKalb County man has been sentenced to eight life sentences plus 135 years in prison for raping or trying to rape five women.

Gary Mincey's sentence was handed down Tuesday in DeKalb County Superior Court. He was found guilty of stalking and attacking women outside a Publix and two other businesses in 2011.

"These women's lives have forever been changed by the heinous acts of a serial rapist. We hope this guilty verdict and sentence will bring some form of relief to each one of our victims and loved ones," DeKalb County Chief Assistant D.A. Nicole Marchand Golden said in a statement.

"Mincey will never live another day as a free man because of the jury's verdict and today's sentence," Golden added. "There is a monster who no longer roams the streets of DeKalb County."

DEKALB COUNTY, Ga. -- A DeKalb County man faces more than 200 years in prison after being found guilty of human trafficking.

Darryl Curry will be sentenced Mar. 26. A DeKalb County jury found him guilty Monday of 13 felony counts, including trafficking, pimping and sexual exploitation of children.

"(Curry) is a monster who preyed upon young and impressionable girls for his own personal and financial gain," DeKalb County District Attorney Robert James said in a statement.

Police began investigating Curry in October 2011, when one of his victims called them. Investigators eventually found a second victim and uncovered evidence against Curry, including videos of him instructing others on how to become pimps and get rich by exploiting women.
