JACKSON, Tenn. (AP) -- A Jackson man has been charged with first-degree murder in the fatal stabbing of his aunt.
Jackson police say a Madison County grand jury indicted 19-year-old Caleb Mullins on Monday in the death of 43-year-old Karen Mullins.
Mullins originally had been charged with second-degree murder after his arrest Nov. 12 in Louisville, Ky., where authorities say they found him with his aunt's sport utility vehicle.
Karen Mullins' body was found on the kitchen floor of her home in Jackson the day before the arrest.
Investigators said they found a knife and bloody clothes during a search of a trash bin at apartments where the victim and her nephew formerly lived.
Caleb Mullins was extradited to Tennessee in December. The Associated Press could not determine if he had a lawyer Monday.
