A Tennessee mother is mourning the death of her daughter — who died when a gun in the woman’s purse fired as she searched for her keys.

Police in Nashville say that DeAnn Radley reported the fatal shooting of her daughter, 13-year-old Dearria Radley, as an accident.

“Midtown Hills Precinct officers responded to the 9:58 p.m. 911 call and rendered immediate aid to Dearria prior to her being transported by ambulance to Vanderbilt’s Pediatric Emergency Room where she died of a single gunshot,” the Metropolitan Nashville Police Department said in a press release Monday. “In an interview at police headquarters, Dearria’s mother told detectives that her unholstered .40 caliber semi-automatic pistol was in her purse with other items. She said it went off as she was attempting to retrieve her keys from the purse.”
