A Houston woman faces up to life in prison after pleading guilty to the neglect-related death of her 9-year-old daughter, whose emaciated body was found in a refrigerator.

Amber Keyes pleaded guilty Friday to felony injury to a child by omission. The 36-year-old Keyes remains in custody pending sentencing by a judge in March.

Keyes was charged a year ago in connection with the death of her daughter, Ayahna Comb, who had cerebral palsy.

Ayahna weighed 14 pounds when some children looking for food found her body in Keyes' refrigerator in June 2014. An autopsy determined Ayahna died of malnutrition and dehydration.

Keyes has said she found Ayahna unresponsive in January 2014, couldn't revive her, wrapped the girl in a blanket and put her body in the refrigerator.
