In a release sent to WSB-TV, Assistant District Attorney Lauryn Perry, who prosecuted the case, said, "Mr. Haynes committed three armed robberies in about 24 hours. The first occurred in Gwinnett County, the second one in Cobb County and the last one in Gwinnett County. He showed a lack of compassion for his victims and a streak of violence that the state believes is reflected in his sentence."
Haynes was previously convicted in Gwinnett County for the two related armed robberies there and was sentenced to life in prison.
In addition to the life in prison sentence, the Cobb County judge also added a mandatory five years to serve in prison on the firearms charge. Haynes’ sentence will run concurrently with the sentence imposed in Gwinnett.
Barnes, 25, pleaded guilty to charges in both counties. He was sentenced in Cobb County to 20 years, with 10 years to be served in prison.
