A McMinn County teen is dead after she was accidentally shot by a gun her brother was handling.

The McMinn County Sheriff's Office said the incident happened off County Road 278 near Niota around 8:45 p.m. Saturday.

The 17-year-old girl was sitting across from her 13-year-old brother when the .223 rifle he was attempting to unload discharged, striking her.

911 dispatchers tried to talk the 13-year-old through performing CPR, but the girl was pronounced dead by first responders when they arrived.

Sheriff Joe Guy extended his condolences to the family.

The investigation is continuing, and no names are being released yet in this incident.
