A 5-year-old victim of arson has died, police sources told News On 6.

The child was inside the home on Tuesday when police say Steven Clement, who is behind bars, set the fire after an argument with the boys' mother.

Sources told us the child was taken off life support this weekend.

An 11-year-old boy also was inside the home and is in critical condition. A 19-year-old and 9-year-old were on the porch when firefighters arrived to the scene at 31st Street and the Broken Arrow Expressway, investigators said.

Clement, 35, was arrested outside of the home for child abuse and arson.

We are waiting to see if he will face additional charges after the child's death.
