(AP) — The parents of a 6-year-old Philadelphia boy who starved to death after returning to their care have been sentenced to 30 to 60 years in prison.

A prosecutor Tuesday called the slow, torturous death of Khalil Wimes “a crime against humanity.”

Khalil had thrived with relatives who raised him until age 3. But Tina Cuffie and Latiff Hadi won him back despite losing custody of five other children.

Common Pleas Judge Barbara McDermott called Khalil nothing but a pawn to them.

She had convicted them of third-degree murder after hearing they locked Khalil in a room, beat him, and made him run laps the day before he died.

Hadi says he keeps a picture of his son in his cell. And Cuffie, the mother of 11 children, says other inmates call her “mom.”
