MIAMI, Okla. (AP) -- Ottawa County prosecutors have charged a Missouri prison inmate with first-degree murder in the death of her infant daughter nearly five years ago.
Kristina Ann Grannis is accused in the Dec. 30, 2001, suffocation death of her 11-week-old daughter, Jacqueline Vincilione.
District Attorney Eddie Wyant said Wednesday he is considering the death penalty for Grannis, 29.
Wyant said her former boyfriend, Jacques Vincilione, also was charged with accessory to first-degree murder.
Wyant alleges that Vincilione confessed to authorities in December that Grannis suffocated the child by pushing her face into the cushion and keeping it there until the baby quit moving.
Vincilione also told authorities he manipulated the crime scene by moving the baby from the couch to her crib where authorities found the baby, Wyant said.
At the time of the infant's death, the autopsy report listed the cause of death as unknown. The report later was amended to homicide, he said.
The baby's body wasn't exhumed.
Grannis is an inmate at Eastern Women's Correctional Facility in Vandelia, Mo., where she is serving an 18-year sentence for assaulting her 3-month-old son, Wyant said.
She doesn't have custody of that child or three of her children.
