The woman has a current conceal carry permit.
From an article:
When officers arrived, they found a 22-year-old woman outside holding her child and administering first aid.
The child had sustained a gunshot wound to his lower abdomen area. EMS arrived, and the child was taken by Lifeflight helicopter to Vanderbilt University Medical Center in Nashville in critical but stable condition.
Detective Ronald Parrish investigated, and, based on preliminary information, determined that the 22-year-old woman, who has a handgun carry permit, took off her Kel Tec .380 handgun and left it unattended on a couch, Knoll said.
Her son was eating at a table in a different area of the apartment. The woman sat down with her back to the couch and was working on the computer when she heard the gunshot.
She looked to see if there was a hole in the ceiling and then saw her son crying and holding his abdomen, Knoll said.
Every gun in the hands of a child must first pass through the hands of an adult.
