Chicago Police: Body Found in SUV Is Hudson's Missing Nephew

Chicago Police say the body they found in an SUV Monday on Chicago's West Side has been identified as Jennifer Hudson's missing nephew, seven-year-old Julian King.

Hudson identified the body Monday afternoon. An autopsy was scheduled for Tuesday.

Julian had been the subject of a frantic search since Hudson's mother and brother were found dead in their Chicago home Friday.

MyFOXChicago reported Monday that police located the SUV, which is believed to be the getaway vehicle driven by William Balfour, a suspect in the murders of the family members of Oscar-winning actress and singer Hudson.

Chicago police confirmed Monday that the vehicle was in fact the white 1994 Chevy Suburban that authorities had been searching for, as the license plates matched the Amber Alert issued in the search for King.

According to Internet reports, the Amber Alert for Julian was called off early Monday afternoon.

Chicago officers located the vehicle at about 7 a.m. Monday morning about 13 miles northwest of the Hudson home. It was later removed by a tow truck with the body inside.

The Amber Alert listed William Balfour, the estranged husband of Julia Hudson, as a suspect in a "double homicide investigation." Balfour, 27, has not been charged in the slayings. He is not the boy's father.

Police said they did not have a motive for the killings but called the case "domestic related."

The medical examiner's office confirmed Hudson identified the bodies of her mother, Darnell Donerson, 57, and 29-year-old brother, Jason Hudson. Their deaths were ruled homicides.

Hudson, 27, who won an Academy Award in 2007 for her role in "Dreamgirls," offered a $100,000 reward Sunday for the safe return of her nephew, who is the son of her sister, Julia Hudson.

Balfour was married to Hudson's sister, Julia, for several years but they were separated, his mother, Michele Balfour said. She said Donerson had ordered him to move out of the family's home last winter.
