A seven-year-old girl kept prisoner by her mother and mother's partner died after being starved for weeks or months, a court has heard.
Khyra Ishaq died of an infection, Birmingham Crown Court was told.
Prosecutors allege it was murder because the couple intended to cause Khyra serious harm.
Khyra's mother Angela Gordon, 34, and Junaid Abuhamza, 30, both of Leyton Road, Handsworth, Birmingham, deny murdering Khyra on 17 May last year.
Jurors have been told UK doctors had rarely seen such a severe case of malnutrition.
Khyra's body mass index at the time of her death was so low that it did not register on available medical charts, the court was told.
Jesus. Or Mohammed, by the sounds of it.
The court heard a lock had been fitted high up on the kitchen door to keep Khyra, and five other children in the care of the couple, away from the food in the home.
Mr Raggatt said if the children were caught stealing food they were made to stand outside in the cold, beaten with a cane, or made to overeat until they were sick.
Jurors were told that Khyra's life changed after her natural parents split up and Ms Gordon and Mr Abuhamza became a couple.
My flabber is ghasted. A mother turned into a complete vicious bitch after meeting up with a Mr Abuhamza, treated her kids like shit?
Khyra was removed from school and Miss Gordon refused to admit visitors to the house - including school staff and police a short time later.
Looks like those lessons have been learned better than ever, really.
