UPDATE: The FBI has since confirmed that the deceased boy found inside the car was Julian King.

The sad discovery of a young boy’s body may have put an end to an Illinois-area Amber Alert.

Earlier this morning, the Chicago Police Department were asked to check on a possible suspicious car. The white Chevy Surburban, which was parked on the city’s west side, matched the description included in Friday’s missing person report. Although a definitive ID has not yet been released, a body found inside is believed to be that of Julian King, Jennifer Hudson’s 7-year-old relative.

Just this past weekend, the Oscar-winner posted a plea on her MySpace page and offered up a $100,000 reward for the safe return of her nephew. Officers began looking for the boy shortly after the bodies of his grandmother and uncle were located late last week. Although he has not yet been charged with any crimes, Julian’s stepfather, William Balfour, has been in police custody since Friday night.

Relatives fearing the worse about King had reportedly scheduled a church vigil for noon today.
