An argument in the home shared by a divorced Knox County couple has apparently ended in gunfire.

The Knox County Sheriff's Department says a Phyllis Campbell was shot twice in the home she shared with her ex-husband on Pioneer Trail, but she appears to have non-life-threatening injuries. She went to the hospital Sunday evening for treatment.

Sheriff's investigators say an aggravated assault charge is pending against the woman's ex-husband, Ronnie Campbell, for the shooting.
