A former Fulton County deputy sheriff who took more than $2,000 in bribes linked to drug deliveries was sentenced to 3 1/2 years in federal prison Tuesday following his conviction on drug and bribery charges.

Marvie Trevino Dingle Jr., 36, of Lithonia pleaded guilty in November to attempted possession with intent to distribute cocaine and to accepting bribes to facilitate cocaine distribution, according to U.S. District Attorney Sally Quillian Yates.

On March 21, 2011, Dingle accepted $700 from an undercover agent to deliver 7 grams of a substance he believed to be cocaine to an inmate inside the Fulton County jail, where he was employed as a deputy sheriff, according to Yates and court testimony. The following month, Dingle accepted $1,500 from an undercover agent to assist in delivering a kilogram of a substance he believed to be cocaine to a man in the Dunwoody area.

"This former deputy sheriff is headed to prison because he chose to profit from the illegal drug trade instead of protecting and serving the people of Fulton County," Yates said in an emailed statement. "He used his uniform and badge to make money by delivering drugs to inmates at the jail and to protect a significant cocaine transaction on the streets."

Dingle's prison sentence will be followed by supervised release for two years.
