The toddler’s body was found Monday night by Jones’ brother, Williams said. He called local police and the Bolivar County Sheriff’s Office was in turn called for assistance.
Mississippi Department of Public Safety spokesman Warren Strain told The AP investigators are working to determine when the toddler died and if it was before she was placed in the oven.
The child’s body was transported to the crime lab for an autopsy.
Jones is in jail with bond set at $500,000.
