Investigators found that Fadhil’s brother was playing with a rifle, and didn’t realize it was real.

The parents, who were home at the time of the shooting, told police they weren't aware there was a firearm in their home, and told officers that a teenager who lives in the home may have bought it without their knowledge.

Police are working with ATF to track where that rifle came from.

Child Protective Services was called to the scene.

This shooting was one of three reported in North Texas on Sunday that involved a child being shot by another child.

Earlier in the day, Arlington police were notified about an 8-year-old who had been shot in the buttocks.

In Fort Worth, police say a 4-year-old girl was fatally shot by her sibling.
