Julian King discovered in a white SUV

The body of a child found on the back seat a white Chevy Suburban has been identified by police as that of Jennifer Hudson‘s nephew, Julian King.

The 7-year-old had suffered multiple gunshot wounds, say US reports.

An Amber Alert to find Julian was issued on Friday – after his grandmother and uncle were found murdered at their Chicago home.

Jennifer, 27, had offered a $100,000 reward for the safe return of the little boy.

On Saturday, her sister Julia made a tearful plea to ‘whoever was holding’ Julian.

‘My greatest fear has already happened, my greatest hope is for having my child. I just want my son,’ Julia said. ‘That’s all I have to say. Just let my baby go.’

Julia’s estranged husband (Julian’s stepdad), William Balfour, is in police custody.
