The Franklin County coroner's office has ruled the case of the woman shot and killed by an undercover Columbus police officer this year as a homicide.
23-year-old Donna Castleberry died of a gunshot wound to the chest. She was shot by Andrew Mitchell during a prostitution sting on the west side after police say she attacked Mitchell with a knife. The coroner's report says Castleberry was shot three times and had cocaine and fentanyl in her system. Mitchell is the focus of a separate criminal investigation, and has been relieved of duty.
