A deputy with the Rockdale County Sheriff's Office resigned after being arrested Saturday for driving drunk and injuring three passengers.

Frances Farmer, of Conyers, resigned from the Rockdale County Sheriff's Office Sunday afternoon after arrest charges were made early Saturday morning.

Around 3:10 a.m. Saturday, a vehicle driven by Farmer left the roadway near 2818 Zingara Road and crashed, injuring three people. RCSO deputies responding to the crash learned that the driver was an off-duty RCSO deputy and that she was apparently under the influence of alcohol. Georgia State Patrol was requested to conduct the accident investigation, since it involved an off duty Rockdale deputy.

Farmer was arrested by the GSP for driving under the influence and transported to the Rockdale County Jail. She bonded out late Saturday afternoon.

At least one passenger was transported to Atlanta Medical Center for their injuries and the other two injured passengers had visible injuries.

Chief Deputy Scott Freeman said, "In any case where we have an RCSO deputy that has been involved in an accident, especially with the suspicion of DUI, we request the GSP to investigate in order to ensure complete transparency and objectivity."

Farmer was placed on administrative leave after she bonded out from jail Saturday and an internal investigation, with the RCSO's Office of Professional Standards, was conducted with a hearing on Sunday. During the hearing, Farmer reportedly requested to resign.

Freeman said, "This is an unfortunate incident in which one our deputies made some very poor decisions, but we are very fortunate that no one was killed. Despite the fact that this incident involved a RCSO deputy, the on scene supervisor that responded to the scene quickly dealt with the situation. By having the GSP conduct the investigation, we have ensured the citizens of Rockdale County that the RCSO is committed to total transparency at all levels inside and outside of the RCSO, and that we are going to hold ourselves to a higher standard."
