Penny Forrest, the wife of Mayor Megan Barry’s former head of security Rob Forrest, has filed for divorce. Court documents show the complaint was filed on Feb. 23 and cites irreconcilable differences and inappropriate marital conduct. According to the divorce complaint, Penny Forrest would show that her husband “has been guilty of inappropriate marital conduct as to render further cohabitation unsafe and improper.”

Rob Forrest’s attorney David Raybin, released a statement on his behalf.

“Mr. Forrest is aware he will shortly be served with divorce papers. He deeply regrets that his conduct will cost him his marriage. Given the intensely personal nature of a divorce, Mr. Forrest asks for privacy for his family at this difficult time. Mr. Forrest and I will have no further statement.”

Mayor Barry last month publicly admitted to a two-year affair with former Metro Police Sgt. Rob Forrest, who was the head of her security detail until he resigned on January 31. The divorce filing states Rob and Penny Forrest separated February 1. Several criminal and ethics investigations have been launched, though Mayor Barry denies breaking any laws or violating policies.
