Boy's body found in Chicago, might be Jennifer Hudson's nephew

As of yet, there has been no confirmation on the identity of the body.

The Cook County Medical Examiner's office and Chicago Police Department sent officials to the scene of a white SUV on the city's West Side Monday.

Julian King, 7, has been missing since Hudson's mother and brother were found dead in their home Friday. He was described as being 4-feet-11 and 130 pounds and was last seen wearing a striped brown polo shirt and khaki pants, according to an Amber Alert released by police.

Over the weekend, Oscar-winning actress Hudson offered a $100,000 reward for the safe return of her nephew.

"Thank you all for your prayers and your calls. Please keep praying for our family and that we get Julian King back home safely," Hudson said in a posting on her MySpace page Sunday.

"If anyone has any information about his whereabouts please contact the authorities immediately."

Hudson's mother Darnell Donerson and her older brother, Jason Hudson, were murdered in Chicago on Friday afternoon.

Police confirm they have taken a person into custody but are not saying who.

News reports, however, say that person is Hudson's brother-in-law, William Balfour. Balfour's mother has also acknowledged her son has been questioned about the shootings.
