LATEST: Jennifer Hudson is "distraught" after police investigating the disappearance of her nephew found the body of a child.
Seven-year-old Julian King went missing on Friday (24Oct08) following the murder of Hudson's mother Darnell Donerson and her brother Jason Hudson at their home in Chicago, Illinois.
The child, son of Hudson's sister Julia, was staying with his grandmother when the shooting took place, and he has not been seen since.
The Dreamgirls star offered a $100,000 (GBP64,100) cash reward for the youngster's safe return and authorities issued an Amber Alert in the search for the missing boy, launching a statewide campaign to find him.
But now the body of an African-American child has been discovered inside a 1994 white Chevy Suburban car in Chicago - believed to be owned by Jason Hudson - leading to fears that Julian King may already be dead.
Hudson's personal assistant, identified only as Jay, called Fox News shortly after the discovery was announced, insisting that the singer/actress is devastated by the possibility that her young nephew may have perished, saying: "She is so distraught she cannot talk."
The car was found on Monday (27Oct08) and has now been removed from the scene in Chicago by authorities. The body had not been identified as WENN went to press.
The vehicle is said to have been reported missing on Friday (24Oct08) and neighbours in the area where it was found reportedly told police it had been parked there since Saturday.
The gruesome find was just a few miles from where Julia's estranged husband, William Balfour, was arrested by police, according to TMZ.com. He is currently being quizzed by cops over the slayings, and authorities have described him as "a person of interest".
