Authorities say they are preparing a first-degree murder charge against a Mississippi grandmother after her 20-month-old granddaughter was found stabbed and burned inside an oven.

Bolivar County Sheriff Kelvin Williams Sr. tells The Associated Press that the grandmother was taken into custody after the child was found dead Monday night at a home in Mississippi Delta town of Shaw.

Williams says he won't release the names of the grandmother or the toddler until the filing of the murder charge is completed.

Mississippi Department of Public Safety spokesman Warren Strain says officials are still investigating the cause of the girl's death, as well as when she died and whether that was before she was placed in the oven. Williams says autopsy results weren't yet complete Tuesday afternoon.

Williams says the grandmother's brother found the body on Monday night and called police.
