Authorities said 49-year-old Robert Wayne Holsey was declared dead at 10:51 pm yesterday at the state prison in Jackson.
Holsey received the death sentence for the December 17, 1995, killing of sheriff's deputy Will Robinson. A jury convicted Holsey in 1997.
Prosecutors said Holsey robbed a Milledgeville convenience store and the clerk immediately called police, describing the suspect and his car.
According to court documents, Robinson pulled Holsey over minutes later and Holsey fired on the deputy as he approached the car. Robinson died of a fatal head wound.
