Typically, a case like this would head toward trial if the parties can’t reach an agreement. Findling could not be immediately reached to discuss next steps for his client.

The new indictment adds to 11 other felony counts Bickers faces as part of the wide-ranging probe of alleged City Hall bribery. Those charges, filed in April, include conspiracy to commit bribery, money laundering, wire fraud, tampering with a witness or informant and filing false tax returns.

Bickers' role has loomed large in the federal investigation. She was a powerful ally of former Atlanta Mayor Kasim Reed and her get-out-the-vote skills have been credited with helping him win in 2009. The next year, she was director of the city's human services department, which she ran until 2013.

Prosecutors allege that while at City Hall she set up a cash-for-contracts scheme that continued after she left the post. The scheme allegedly included snow removal and sidewalks contracts and prosecutors also are looking into any connections with Hartsfield-Jackson International Airport and the city's watershed department.

The bribery charge connected to Jackson, Miss., alleges that in 2014 and 2015, Bickers sought contracts with that city’s mayor and other officials by paying for parties, food, airline flights and hotels. She also is being investigated for unsuccessful efforts to win a contract for a convention center hotel project in Jackson as well as part of a program management services contract for the city’s Wastewater department.

“On or about May 2015, Bickers represented to a public employee that the mayor promised she would receive a government contract with the city of Jackson and Bickers simply needed to ensure that the paperwork looked good enough to justify the award,” according to the indictment.

Tony Yarber, who was mayor during this period, is not named or charged in the indictment.

At the time of her arrest in April, Bickers was working as a chaplain with the Clayton County Sheriff's Office.
