The woman accused of helping plan the armed robbery of a postal worker has been indicted on federal charges, the U.S. Attorney's Office said Thursday.

LaTonya Evans, indicted by a federal grand jury on conspiracy and armed robbery charges, is the third defendant to be indicted for the robbery that led to the near-fatal shooting of the driver, U.S. Attorney Sally Quillian Yates said.

"Evans is charged with exploiting her inside knowledge of the Postal Service for personal profit," Yates said in an emailed statement. "The conspiracy she is charged with participating in resulted in the near-death of a fellow postal worker whom Evans knew. The indictment charges that he was shot, bound, and left for dead by Evans' co-defendants."

Evans helped to develop the scheme to rob a postal truck, and worked with co-defendants Kendrick Watkins and Charles Jackson to carry out the plan, Yates said. Watkins, of Rex, and Jackson, of Griffin, were indicted in February.

On Dec. 20, a postal truck driver conducting a routine mail pick-up in DeKalb County was approached by two robbers, later identified as Watkins and Jackson, who demanded the truck's keys before shooting the victim in the torso, leaving him critically injured, according to investigators. After shooting the driver, Jackson and Watkins also allegedly bound the man's feet and took his cell phone before driving away in the postal truck, investigators said. The victim crawled several hundred feet to the nearest road, where he flagged down a passerby for help.

Trial dates have not yet been announced.
