Jennifer Hudson's publicist says the Oscar-winning actress and her family are offering a $US100,000 ($NZ174,367.91) reward for the safe return of her missing seven-year-old nephew.
Hudson's nephew, Julian King, has been missing since the Friday shooting deaths of her mother and brother at the family's home on Chicago's South Side.
Hudson publicist Lisa Kasteler issued a statement on Sunday evening saying the actress and her family would offer the reward. The family asks that any information be given to the Chicago Police Department.
The reward came the same day police ramped up search efforts for Julian and transferred custody of a "person of interest" in the killings to state authorities.
