CHICAGO (AP) - Police searching for Jennifer Hudson's missing 7-year-old nephew say they've found the body of a young black boy in an SUV. There is no confirmation on the identity of the body.

A spokesman for the Cook County Medical Examiner's office says they've sent investigators to the scene. A spokeswoman for the Chicago Police Department refused to comment Monday.

Julian King hasn't been seen since Friday. That's when Hudson's mother and brother were found shot to death in their home.

Authorities issued an Amber Alert for the 7-year-old and were looking for a 1994 white Chevrolet Suburban. The Oscar-winning actress offered a $100,000 reward for his safe return.

Julian is the son of Jennifer Hudson's sister, Julia Hudson.

Police on Sunday transferred custody of a "person of interest" in the killings to state authorities.
